Overview

We are aclinical-stage biopharmaceutical company developing novel, immune-modulating cancer therapies based on our T-win technology platform. Our product candidates are designed to induce the immune system tosimultaneously target and disrupt multiple pathways that regulate tumor-induced immunosuppression. We believe this represents a paradigm shift in the management of cancer and that our product candidates have the potential to become cornerstones ofthe treatment regimens of multiple solid tumors. Our lead product candidate, IO102-IO103, is designed to target the immunosuppressive mechanisms mediated by key immunosuppressive proteins such as Indoleamine 2,3-dehydrogenase (IDO) and programmeddeath ligand (PD-L1). In a single-arm Phase 1/2 clinical trial (the MM1636 trial) of 30 patients with metastatic melanoma with the primary objective to investigate safety and tolerability, secondary objective to investigate immunogenicity andtertiary objective to investigate clinical efficacy, IO102-IO103, in combination with nivolumab, demonstrated an ability to induce meaningful tumor regression and establish durable antitumor response while achieving a manageable tolerability profilefor patients. The clinical efficacy endpoints in this trial include objective response (OR), progression free survival (PFS) and overall survival (OS). In this trial, we have observed a confirmed overall response rate (ORR) of 73% and a completeresponse (CR) rate (CRR) of 47%. Based on the results from this trial, IO102-IO103, in combination with pembrolizumab was granted Breakthrough Therapy Designation (BTD) by the U.S. Food and Drug Administration (FDA) for treatment ofunresectable/metastatic melanoma and we are currently planning a potentially registrational Phase 3 trial for IO102-IO103 in combination with pembrolizumab.

Our T-win Technology Platform

Our T-win platform is a novel approach to cancer immunotherapy designed to activatenaturally occurring T cells to target immunosuppressive mechanisms. Our T-win product candidates are designed to employ a dual mechanism of action: (1) direct killing of immunosuppressive cells, including bothtumor cells and genetically stable cells in the tumor microenvironment (TME), that express key immunosuppressive proteins such as IDO and PD-L1, and (2) modulation of the TME into a more pro-inflammatory, anti-tumor environment. Our T-win technology is built upon our team’s deep understanding of both the TME and a tumor’s ability to evadesurveillance and destruction by the immune system. Our approach is in contrast to previous methods that have sought to either block single immunosuppressive pathways or to direct the immune system against specific identified antigens expressed bytumor cells.

Our Immunotherapy Pipeline

We are developing a pipeline of product candidates that leverage our T-win technologyplatform to address targets within the TME. In addition to a potentially registrational Phase 3 trial in melanoma, we are planning two Phase 2 basket trials in additional solid tumors and treatment settings. Basket trials involve a singleinvestigational drug or drug combination studied across multiple cancer populations defined by disease stage, histology, number of prior

therapies, genetic or other biomarkers, or demographic characteristics. We are also developing earlier stage product candidates that target additional immunosuppression-related targets that areexpressed in a broad range of solid tumors. We expect to use these earlier stage product candidates in combination with our existing pipeline candidates. Our pipeline of product candidates is summarized in the table below.

Our Lead Product Candidate: IO102-IO103

Our lead product candidate, IO102-IO103, combines our two fully-owned, novel immunotherapeutics, IO102 and IO103, which aredesigned to target IDO and PD-L1 expressing cells, respectively. IDO and PD-L1 are often dysregulated and over-expressed in a wide range of solid tumors, and result in the inhibition of the body’s naturalpro-inflammatory anti-tumor response within the TME. IO102-IO103 is designed to employ our novel dual mechanism of action approach, leading to killing of cells expressing IDO and PD-L1 and modulation of theTME into an enhanced pro-inflammatory environment. This is in contrast to previous approaches which have sought to block single immunosuppressive pathways or to direct the immune system against specific identified antigens expressed by tumor cells.By combining IO102 and IO103 in a single treatment regimen, we also aim to provide a synergistic effect on tumors.

OnDecember 14, 2020, the FDA granted us BTD for IO102-IO103 in combination with an anti-programmed cell-death protein 1 (PD-1) monoclonal antibody for the treatment of patients with unresectable ormetastatic melanoma based on data from the MM1636 Phase 1/2 clinical trial. BTD enables us to solicit guidance from the FDA as to how to conduct an efficient development program for IO102-IO103. The MM1636 trial is an investigator initiated, single-arm Phase 1/2 trial of 30 anti PD-1/PD-L1 naïve patients with metastatic melanoma receiving IO102-IO103 and nivolumab, an anti-PD-1 monoclonal antibody. In this trial, investigators initially observed an ORR of 80% (24 out of 30 patients); however, two of 24 patients in which a response wasobserved progressed before subsequent radiological confirmation, which resulted in a confirmed ORR of 73%. In addition, 47% of patients achieved a CR, or complete elimination of their tumors based on Response Evaluation Criteria in Solid Tumors(RECIST) 1.1 definitions. While a total of five patients (17%) experienced a high-grade

adverse event (grade 3-5), as further discussed in the section titled “Business—Our Product Candidates—Dual Epitope IO102-IO103—Development of Dual Epitope IO102-IO103 in theFirst-line Setting—Tolerability,” based on the 17% discontinuation rate of treatment with both nivolumab and IO102-IO103, data from this trial suggests a manageable tolerability profile for patients. In addition, we have observedtreatment-induced infiltration of CD3/CD8 T cells into the tumor site in responding patients and detected IO102+IO103-specific T cells in tumors after treatment in correlative biomarker data where this was analyzed. We are currentlyplanning a Phase 3 potentially registrational trial for IO102-IO103 in combination with pembrolizumab, which we expect to initiate by the end of 2021. While the MM1636 trial investigates IO102-IO103 in combination with nivolumab, we have madethe commercial decision to investigate IO102-IO103 in combination with pembrolizumab in the upcoming Phase 3 trial. Nivolumab and pembrolizumab are both IgG4 subclass antibodies that target the PD-1 receptor. In a comparative data analysis by Moser(Annals of Oncology 2020), researchers found no difference between the effectiveness of frontline pembrolizumab and nivolumab in patients with advanced melanoma. The Phase 3 trial will include a concurrent evaluation of the initial participants toallow for an assessment of safety, or safety run in. The pembrolizumab for this trial will be supplied by Merck & Co., Inc. (Merck) pursuant to a Clinical Trial Collaboration and Supply Agreement that we entered into in September 2021.

We plan to broaden the development of IO102-IO103 to several other first-line solid tumor indications. We intend to conduct aPhase 2 basket trial, the IOB-022 trial, that will enable us to investigate multiple first-line solid tumor indications in anti PD-1/PD-L1 treatment naïve patientswith metastatic disease. This planned basket trial will investigate the safety and efficacy of IO102-IO103 in combination with pembrolizumab in non-small cell lung cancer (NSCLC) with PD-L1 ³50%, squamous cell carcinoma of the head and neck (SCCHN), and urothelial bladder cancer (UBC). In addition to first-line cancer indications, we also plan toinvestigate IO102-IO103 when used before or after curatively intended surgery as a neo-adjuvant/adjuvant therapy. As with our targeted first-line cancer indications, we plan to conduct a Phase 2 basket trial,the IOB-032 trial, that will enable us to investigate multiple first-line solid tumor indications in anti PD-1/PD-L1 naïve settings focused initially on melanomaand SCCHN.

Our development of IO102-IO103 is based on our prior separate development of IO102 and IO103. IO102 is ourfully-owned novel product candidate containing a single IDO-derived peptide sequence designed to engage and activate IDO-specific human T cells. This contrasts to smallmolecule IDO inhibitors that aim to address tumors by inhibiting IDO pathways. IDO small molecule inhibitors have shown clinical potential in combination with PD-1 antibodies in early clinical trials, but have not demonstrated the same level ofefficacy in later-stage clinical trials. Our Phase 1 non-randomized trial of IO101, our first generation IDO therapy, in NSCLC resulted in proof of concept for our approach, with 47% of patients displaying clinical benefit and an OS of 26 months inthe treatment arm compared to 8 months in the group receiving standard of care. There were no grade 3 or higher adverse events in this trial. IO102 is currently being evaluated in a randomized Phase 1/2 trial in combination with pembrolizumab in thefirst-line treatment of patients with metastatic NSCLC. IO103 is our fully-owned, novel product candidate containing a single PD-L1-derived peptide designed to engageand activate PD-L1 specific human T cells. Continued clinical development of IO102 and IO103 will be focused on their use in our dual- and multi-antigen approaches.

Our Earlier Stage Product Candidates

IO112 is our fully-owned, novel product candidate containing a single Arginase1-derived peptide designed to engage and activate Arginase 1-specific human T cells. IO112 is designed to target T cells that recognize epitopes derived from Arginase 1,an immunoregulatory enzyme highly expressed in difficult-to-treat tumors associated with high levels of myeloid-derived suppressor cells (MDSCs) including colorectal,breast, prostate and pancreatic and ovarian cancers. Arginase overexpression is a well-documented tumor escape mechanism. We plan to file an Investigational New Drug/Clinical Trial Application (IND/CTA) for IO112 in the first half of 2022 and moveinto a Phase 1/2 trial in mid-2022 in combination with IO102 and IO103.

Table of Contents

In addition to IO102, IO103 and IO112, we are evaluating additionalcandidates that we believe have potential for use in solid tumors. All our compounds in preclinical development are designed to target well-documented immunosuppressive molecules that are known to be overexpressed in the TME across a wide range oftumors. These targets provide additional opportunities across multiple cancer indications.

Our History and Team

We were established in December 2014 as a spin-off of the National Center for CancerImmune Therapy at Herlev University Hospital in Denmark. We have assembled a seasoned management team and board of directors with extensive experience in developing novel oncology therapies, including advancing product candidates from preclinicalresearch through to clinical development and ultimately to regulatory approval. Our team is led by our founder and Chief Executive Officer, Mai-Britt Zocca, Ph.D., who has close to 20 years of experience as abiotech executive. Keith Vendola, M.D., M.B.A., our Chief Financial Officer, has more than 20 years of experience in healthcare corporate finance as an executive, adviser, and investment banker working on over 50 financing and strategictransactions. Eva Ehrnrooth, M.D., Ph.D., our Chief Medical Officer, is a clinical oncologist and has more than 20 years of experience in oncology and drug development. Mads Hald Andersen, Ph.D., our scientific founder and advisor, is a Professorand director at the National Center for Cancer Immune Therapy, Herlev University Hospital and an internationally recognized immunology researcher. Muhammad Al-Hajj, Ph.D., our Chief Scientific Officer, is awell-respected scientific leader with a proven-track record in the field of immuno-oncology and expertise in translational medicine and biomarker discovery. Our board of directors has deep expertise in the fields of immuno-oncology, business andfinance.

Our Strategy

To achieve our goals, we aim to leverage our T-win platform to transform cancertreatment by creating a broad portfolio of immuno-oncology therapies focused on targets within the TME.

The key elementsof our strategy are to:

 

  

Advance our lead product candidate, IO102-IO103, toward approval in combination with anti-PD-1 therapy in first-line treatment of advanced melanoma;

 

  

Broaden clinical development of IO102-IO103 into other first-line solid tumors settings through baskettrials in the first line metastatic and neo-adjuvant/adjuvant treatment settings;

 

  

Leverage our T-win technology platform to design and advance aportfolio of novel immunotherapy compounds, including IO112 and additional future product candidates;

 

  

Strengthen our position in the immunotherapy field through the continuous innovation and expansion of our T-win platform;

 

  

Maximize the value of our product candidates and pipeline by selectively entering into strategiccollaborations; and

 

  

Build a leading immuno-oncology company while maintaining a strong culture of innovation, valuing diversityand putting patients at the center of everything we do.

Recent Developments

In satisfaction of certain investors’ funding obligations under the Class C Investment Agreement entered into in January2021, which provided for a milestone closing in the event that we met certain development milestones before April 2022, upon the public filing of this registration statement, $84.1 million will be released from escrow to the Company.

Implications of being an Emerging Growth Company and a Smaller Reporting Company

The Jumpstart Our Business Startups Act (the JOBS Act) was enacted in April 2012 with the intention of encouraging capitalformation in the United States and reducing the regulatory burden on newly public companies that qualify as emerging growth companies. We are an “emerging growth company” within the meaning of the JOBS Act. We may take advantage of certainexemptions from various public reporting requirements, including the requirement that we provide more than two years of audited financial statements and related management’s discussion and analysis of financial condition and results ofoperations, and that our internal control over financial reporting be audited by our independent registered public accounting firm pursuant to Section 404 of the Sarbanes-Oxley Act of 2002 (the Sarbanes-Oxley Act). In addition, the JOBS Actprovides that an “emerging growth company” can delay adopting new or revised accounting standards until those standards apply to private companies. We intend to take advantage of these exemptions until we are no longer an emerging growthcompany. We have elected to use the extended transition period to enable us to comply with new or revised accounting standards that have different effective dates for public and private companies until the earlier of the date we (1) are nolonger an emerging growth company and (2) affirmatively and irrevocably opt out of the extended transition period provided in the JOBS Act. As a result, our financial statements may not be comparable to companies that comply with new or revisedaccounting pronouncements as of public company effective dates.

We will cease to be an emerging growth company upon theearliest of (1) the end of the fiscal year following the fifth anniversary of this offering; (2) the last day of the fiscal year during which our annual gross revenues are $1.07 billion or more; (3) the date on which we have,during the previous three-year period, issued more than $1.0 billion in non-convertible debt securities; and (4) the end of any fiscal year in which the market value of our common stock held by non-affiliates exceeded $700.0 million as of the end of the second quarter of that fiscal year.

Additionally, we are a “smaller reporting company meaning that the market value of our stock held by non-affiliates plus the proposed aggregate amount of gross proceeds to us as a result of this offering is less than $700 million and our annual revenue was less than $100 million during the most recentlycompleted fiscal year. Smaller reporting companies may take advantage of certain reduced disclosure obligations, including, among other things, providing only two years of audited financial statements in our Annual Report on Form 10-K, and, similar to emerging growth companies, smaller reporting companies have reduced disclosure obligations regarding executive compensation. We will remain a smaller reporting company until the last day of thefiscal year in which (i) the market value of our common stocks held by non-affiliates exceeds $250 million as of the end of that year’s second fiscal quarter, or (ii) our annual revenuesexceeded $100 million during such completed fiscal year and the market value of our common stocks held by non-affiliates exceeds $700 million as of the end of that year’s second fiscal quarter.To the extent we take advantage of such reduced disclosure obligations, it may also make comparison of our financial statements with other public companies difficult or impossible.

See the section titled “Risk Factors—Risks Relating to Our Initial Public Offering and Ownership of Our CommonStock—We are an “emerging growth company” and a “smaller reporting company,” and the reduced disclosure requirements applicable to emerging growth companies and smaller reporting companies may make our common stocks lessattractive to investors.”

RISK FACTORS

Investing in our common stock involves a high degree of risk. You should consider and read carefully all of the risks anduncertainties described below, as well as other information included in this prospectus, including our financial statements and related notes appearing at the end of this prospectus, before making an investment decision. The risks described beloware not the only ones facing us. The occurrence of any of the following risks or additional risks and uncertainties not presently known to us or that we currently believe to be immaterial could materially and adversely affect our business, financialcondition or results of operations. In such case, the trading price of our common stock could decline, and you may lose all or part of your investment. This prospectus also contains forward-looking statements and estimates that involve risks anduncertainties. Our actual results could differ materially from those anticipated in the forward-looking statements as a result of specific factors, including the risks and uncertainties described below.

Risks Related to Limited Operating History, Financial Position and Capital Requirements

We have a limited operating history, have incurred net losses since our inception, and anticipate that we will continueto incur significant losses for the foreseeable future. We may never generate any revenue or become profitable or, if we achieve profitability, may not be able to sustain it.

We are a clinical-stage biopharmaceutical company with a limited operating history that may make it difficult to evaluate thesuccess of our business to date and to assess our future viability. Our operations to date have been limited to organizing and staffing our company, business planning, raising capital, developing and optimizing our technology platform, identifyingpotential product candidates, undertaking research, preclinical studies and clinical trials for our product candidates, establishing and enhancing our intellectual property portfolio, and providing general and administrative support for theseoperations. IO102-IO103 is in early clinical development and IO112 is in preclinical development, and none of our product candidates have been approved for commercial sale. We have never generated any revenue from product sales and have incurred netlosses each year since we commenced operations. For the years ended December 31, 2019 and 2020, our net losses were $10.7 million and $12.0 million, respectively, and for the six months ended June 30, 2020 and 2021, our net losseswere $6.0 million and $45.5 million, respectively. We expect that it will be several years, if ever, before we have a product candidate ready for regulatory approval and commercialization. We expect to incur increasing levels of operating lossesover the next several years and for the foreseeable future as we advance our product candidates through clinical development. Our prior losses, combined with expected future losses, have had and will continue to have an adverse effect on ourstockholders’ deficit and working capital.

To become and remain profitable, we must develop and eventuallycommercialize a product or products with significant market potential. This will require us to be successful in a range of challenging activities, including completing preclinical studies and clinical trials of our product candidates, obtainingmarketing approval for these product candidates, manufacturing, marketing and selling those products for which we may obtain marketing approval and satisfying any post-marketing requirements. We may never succeed in these activities and, even if wesucceed in commercializing one or more of our product candidates, we may never generate revenue that is significant or large enough to achieve profitability. In addition, as a young business, we may encounter unforeseen expenses, difficulties,complications, delays and other known and unknown challenges. If we do achieve profitability, we may not be able to sustain or increase profitability on a quarterly or annual basis and we will continue to incur substantial research and developmentand other expenditures to develop and market additional product candidates. Our failure to become and remain profitable would decrease the value of the company and could impair our ability to raise capital, maintain our research and developmentefforts, expand our business or continue our operations. A decline in the value of our company could also cause our stockholders to lose all or part of their investment.

Even if this offering is successful, we will need to obtainsubstantial additional funding to complete the development and commercialization of our product candidates. If we are unable to raise this capital when needed, we may be forced to delay, reduce or eliminate our product development programs or otheroperations.

Since our inception, we have used substantial amounts of cash to fund our operations and expect ourexpenses to increase substantially during the next few years. The development of biopharmaceutical product candidates, especially immune-oncology product candidates, is capital intensive. As our product candidates enter and advance throughpreclinical studies and clinical trials, we will need substantial additional funds to expand our clinical, regulatory, quality and manufacturing capabilities. In addition, if we obtain marketing approval for any of our product candidates, we expectto incur significant commercialization expenses related to marketing, sales, manufacturing and distribution. Furthermore, upon the completion of this offering, we expect to incur additional costs associated with operating as a public company.

As of June 30, 2021, we had $54.8 million in cash and cash equivalents. Based upon our current operating plan, we estimatethat our existing cash and cash equivalents as of the date of this prospectus, together with the estimated net proceeds from this offering, will be sufficient to fund our operating expenses and capital expenditure requirements for        . However, the expected net proceeds from this offering may not be sufficient to fund any of our product candidates through regulatory approval, and we may need to raise substantial additional capitalto complete the development and commercialization of our product candidates.

We have based these estimates on assumptionsthat may prove to be incorrect or require adjustment as a result of business decisions, and we could utilize our available capital resources sooner than we currently expect. Our future capital requirements will depend on many factors, some of whichare outside of our control, including:

 

  

the initiation, design, progress, timing, costs and results of drug discovery, preclinical studies andclinical trials of our product candidates, and in particular the clinical trials for IO102-IO103;

 

  

the number and characteristics of product candidates that we pursue;

 

  

the number of clinical trials needed for regulatory approvals from the FDA, the European Commission (based onrecommendation from the European Medicines Agency (EMA)), and any other regulatory authority;

 

  

the length of our clinical trials, including, among other things, as a result of delays in enrollment,difficulties enrolling sufficient subjects or delays or difficulties in clinical trial site initiations;

 

  

successfully complete ongoing pre-clinical studies and clinicaltrials;

 

  

the outcome, timing and costs of seeking regulatory approvals from the FDA, the European Commission, and anyother regulatory authority;

 

  

the costs of manufacturing our product candidates, in particular for clinical trials in preparation formarketing approval and in preparation for commercialization;

 

  

the costs of any third-party products used in our combination clinical trials that are not covered by suchthird party or other sources;

 

  

the costs associated with hiring additional personnel and consultants as our preclinical, manufacturing andclinical activities increase;

 

  

the receipt of marketing approval and revenue received from any commercial sales of any of our productcandidates, if approved;

 

  

the cost of commercialization activities for any of our product candidates, if approved, including marketing,sales and distribution costs;

Table of Contents
  

the emergence of competing therapies and other adverse market developments;

 

  

the ability to establish and maintain strategic collaboration, licensing or other arrangements and thefinancial terms of such agreements;

 

  

the extent to which we in-license or acquire other products andtechnologies;

 

  

the amount and timing of any payments we may be required to make pursuant to our current or future licenseagreements;

 

  

the costs involved in preparing, filing, prosecuting, maintaining, expanding, defending and enforcing patentclaims, including litigation costs and the outcome of such litigation;

 

  

our need and ability to retain key management and hire scientific, technical, business, and medical personnel;

 

  

our implementation of additional internal systems and infrastructure, including operational, financial andmanagement information systems;

 

  

or costs associated with expanding our facilities or building out our laboratory space;

 

  

the effects of the recent disruptions to and volatility in the credit and financial markets in the UnitedStates and worldwide from the COVID-19 pandemic, including any additional costs to our operations related to any future COVID-19 outbreaks; and

 

  

the costs of operating as a public company.

We will require additional capital to achieve our business objectives. Additional funds may not be available on a timelybasis, on favorable terms, or at all, and such funds, if raised, may not be sufficient to enable us to continue to implement our long-term business strategy. Further, our ability to raise additional capital may be adversely impacted by potentialworsening global economic conditions and the recent disruptions to and volatility in the credit and financial markets in the United States and worldwide resulting from the ongoing COVID-19 pandemic. If we areunable to raise sufficient additional capital, we could be forced to curtail our planned operations and the pursuit of our growth strategy.

Raising additional capital may cause dilution to our stockholders, including purchasers of common stock in thisoffering, restrict our operations or require us to relinquish rights to our technologies or product candidates.

Until such time, if ever, as we can generate substantial product revenue, we expect to finance our operations through equityofferings, debt financings or other capital sources, including potentially grants, collaborations, licenses or other similar arrangements. To the extent that we raise additional capital through the sale of equity or convertible debt securities, ourstockholders’ ownership interest will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect the rights of holders of our common stock. Additional debt financing, if available, mayinvolve agreements that include covenants further limiting or restricting our ability to take specific actions, such as further limitations on our ability to incur additional debt, make capital expenditures or declare dividends.

If we raise funds through collaborations or licensing arrangements with third parties, we may have to relinquish valuablerights to our technologies, future revenue streams, research programs or product candidates or grant licenses on terms that may not be favorable to us. If we are unable to raise additional funds when needed, we may be required to delay, limit,reduce or terminate our product development or future commercialization efforts or grant rights to develop and market product candidates that we would otherwise prefer to develop and market ourselves.

We have identified a material weakness in our internal control overfinancial reporting. If we are unable to remedy our material weakness, or if we fail to establish and maintain effective internal controls, we may be unable to produce timely and accurate financial statements, and we may conclude that our internalcontrol over financial reporting is not effective, which could adversely impact our investors’ confidence and our stock price.

Prior to this offering, we were a private company and had limited accounting and financial reporting personnel and otherresources with which to address our internal controls and related procedures. In connection with the audit of our financial statements for the years ended December 31, 2020 and 2019, we and our independent registered public accounting firmidentified a material weakness in our internal control over financial reporting. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting as defined under the Securities Exchange Act of1934, as amended (the Exchange Act) and by the Public Company Accounting Oversight Board (United States), such that there is a reasonable possibility that a material misstatement of our annual or interim financial statements will not be prevented ordetected on a timely basis. The material weakness relates to our financial statement close process, primarily related to the lack of required finance capacity, knowledge or expertise to perform the financial statement close in a timely and accuratemanner or to account for certain complex areas of U.S. Generally Accepted Accounting Principles (GAAP).

We are in theprocess of implementing measures designed to improve our internal control over financial reporting to remediate this material weakness. For example, we recently hired a new Chief Financial Officer. We also plan to design and implement improvedprocesses and internal controls, including ongoing senior management review and audit committee oversight. Additionally, we plan to further develop and implement formal policies, processes and documentation procedures relating to our financialreporting, including the oversight of third-party service providers. The actions that we are taking are subject to ongoing executive management review and will also be subject to audit committee oversight. We expect to incur additional costs toremediate this material weakness, primarily external consulting fees. We cannot assure you that the measures we have taken to date, together with any measures we may take in the future, will be sufficient to remediate the control deficiency that ledto the material weakness in our internal control over financial reporting or to avoid potential future material weaknesses. In addition, neither our management nor an independent registered public accounting firm has ever performed an evaluation ofour internal control over financial reporting in accordance with the provisions of the Sarbanes-Oxley Act because no such evaluation has been required. Had we or our independent registered public accounting firm performed an evaluation of ourinternal control over financial reporting in accordance with the provisions of the Sarbanes-Oxley Act, additional material weaknesses may have been identified. If we are unable to successfully remediate our existing or any future material weaknessin our internal control over financial reporting, or if we identify any additional material weakness, the accuracy and timing of our financial reporting may be adversely affected, we may be unable to maintain compliance with securities lawrequirements regarding timely filing of periodic reports in addition to applicable stock exchange listing requirements, investors may lose confidence in our financial reporting, and our stock price may decline as a result. We also could becomesubject to investigations by Nasdaq, the U.S. Securities and Exchange Commission (the SEC), or other regulatory authorities.

Risks Related to theDiscovery, Development and Regulatory Approval of Our Product Candidates

Our development efforts are in theearly stages. All of our product candidates are in clinical development or in preclinical development. if we are unable to advance our product candidates through clinical development, obtain regulatory approval and ultimately commercialize ourproduct candidates, or experience significant delays in doing so, our business will be materially harmed.

There isno assurance that clinical trials of IO102-IO103, or any other future clinical trials of our product candidates, will be successful or will generate positive clinical data and we may not receive marketing approval from the FDA, European Commission,or other regulatory authorities for any of our product candidates. With have limited experience submitting INDs to the FDA. IO112 is in initial clinical development, currently being

 

14


Table of Contents

studied in an ongoing investigator initiated study. There can be no assurance that the FDA will permit any of our future INDs, including any IND for IO112, to go into effect in a timely manner orat all. Without an IND for a product candidate, we will not be permitted to conduct clinical trials in the United States of such product candidate.

Biopharmaceutical development is a difficult, long, time-consuming, expensive and uncertain process, and delay or failure canoccur at any stage of any of our clinical trials. Failure to obtain regulatory approval for our product candidates will prevent us from commercializing and marketing our product candidates. The success in the development of our product candidateswill depend on many factors, including:

 

  

timely and successful completion of preclinical studies;

 

  

sufficiency of our financial and other resources to complete the necessary preclinical studies and clinicaltrials;

 

  

obtaining and maintaining patent, trademark and trade secret protection and regulator exclusivity for ourproduct candidates and otherwise protecting our rights in our intellectual property portfolio;

 

  

submission of INDs and CTAs for and receipt of allowance to proceed with our planned clinical trials or otherfuture clinical trials;

 

  

initiating, enrolling, and successfully completing clinical trials;

 

  

obtaining positive results from our preclinical studies and clinical trials that support a demonstration ofefficacy, safety, and durability of effect for our product candidates;

 

  

receiving approvals for commercialization of our product candidates from applicable regulatory authorities;

 

  

the outcome, timing and cost of meeting regulatory requirements established by the FDA, European Commission(based on recommendation from the EMA), and other regulatory authorities;

 

  

establishing sales, marketing and distribution capabilities and successfully launching commercial sales of ourproducts, if and when approved, whether alone or in collaboration with others;

 

  

maintaining a continued acceptable safety, tolerability and efficacy profile of any approved products;

 

  

setting acceptable prices for our product and obtaining coverage and adequate reimbursement from third-partypayors;

 

  

acceptance of our products, if and when approved, by patients, the medical community and third-party payors;manufacturing our product candidates at an acceptable cost; and

 

  

maintaining and growing an organization of scientists, medical and clinical professionals and business peoplewho can develop and commercialize our products and technology.

Many of these factors are beyond ourcontrol, including the time needed to adequately complete clinical testing, the regulatory submission process and potential threats to our intellectual property rights. It is possible that none of our product candidates will ever obtain regulatoryapproval, even if we expend substantial time and resources seeking such approval. If we do not achieve one or more of these factors in a timely manner or at all, or any other factors impacting the successful development of biopharmaceuticalproducts, we could experience significant delays or an inability to successfully develop our product candidates, which would materially harm our business.

The results of preclinical studies and early clinical trials are not always predictive of future results. Any productcandidate that we advance in clinical trials, including IO102-IO103, may not achieve favorable results in later clinical trials, if any, or receive marketing approval.

The research and development of drugs and biological products is extremely risky. Only a small percentage of product candidatesthat enter the development process ever receive marketing approval. Before obtaining

 

15


Table of Contents

marketing approval from regulatory authorities for the sale of our product candidates, we must conduct extensive clinical trials to demonstrate the safety and efficacy of the product candidatesin humans. The outcome of clinical testing is uncertain. We may face unforeseen challenges in our product candidate development strategy, and we can provide no assurances that we will ultimately be successful in our current and future clinicaltrials or that our product candidates will be able to receive regulatory approval. The results of preclinical studies and early clinical trials of our product candidates may not be predictive of the results of later-stage clinical trials. Forexample, it is not uncommon for product candidates to exhibit unforeseen safety or efficacy issues when tested in humans despite promising results in preclinical animal models. In particular, while with IO102-IO103 in combination with an anti-PD-1 monoclonal antibody has been investigated in a Phase 1/2 trial in 30 metastatic melanoma patients at University Hospital of Copenhagen, we do not know howIO102-IO103 will perform in the upcoming Phase 3 clinical trial combining IO102-IO103 with an anti-PD-1 monoclonal antibody in first line treatment of advancedmelanoma patients or in other future clinical trials, including the planned Phase 2 clinical trial with IO102-IO103 in basket trials of solid tumors and any future trials of IO112. Future results of preclinical and clinical testing of ourproduct candidates are also less certain due to the novel and relatively untested nature of the approach of our T-win technology platform. In general, clinical trial failure may result from a multitude offactors including flaws in study design, dose selection, patient enrollment criteria and failure to demonstrate favorable safety or efficacy traits. As such, failure in clinical trials can occur at any stage of testing. A number of companies in thebiopharmaceutical industry, including immune-oncology companies, have suffered setbacks in the advancement of clinical trials due to lack of efficacy or adverse safety profiles, notwithstanding promising results in earlier trials.

Our product candidates are based on novel technologies that target the highly immunosuppressive tumor microenvironment,which makes it difficult to predict the results, timing, and cost of product candidate development and likelihood of obtaining regulatory approval.

We have concentrated our research and development efforts on product candidates using ourT-win technology platform, and our future success depends on the successful development of this approach. Our product candidates target the tumor microenvironment which is highly immunosuppressive. We have notyet succeeded and may not succeed in demonstrating efficacy and safety for any product candidates based on our platform technologies in clinical trials or in obtaining marketing approval thereafter, and use of our platform technologies may not everresult in marketable products. We may also experience delays in developing a sustainable, reproducible and scalable manufacturing process or transferring that process to commercial partners or establishing our own commercial manufacturingcapabilities, which may prevent us from completing our clinical trials or commercializing any products on a timely or profitable basis, if at all.

In addition, the clinical trial requirements of the FDA, and other regulatory authorities and the criteria these regulatorsuse to determine the safety and efficacy of a product candidate vary substantially according to the type, complexity, novelty and intended use and market of the potential products. The regulatory approval process for novel product candidates such asours can be less predictable, more expensive and longer than for other, better known or extensively studied pharmaceutical or other product candidates.

There is no assurance that the approaches offered by our products will gain broad acceptance among doctors or patients or thatgovernmental agencies or third-party medical insurers will be willing to provide reimbursement coverage for proposed product candidates. Since our current product candidates and any future product candidates will represent novel approaches totreating various conditions, it may be difficult, in any event, to accurately estimate the potential revenues from these product candidates. Accordingly, we may spend significant capital trying to obtain approval for product candidates that have anuncertain commercial market. The market for any products that we successfully develop will also depend on the cost of the product. We do not yet have sufficient information to reliably estimate what it will cost to commercially manufacture ourcurrent product candidates, and the actual cost to manufacture these products could materially and adversely affect the commercial viability of these products. If we do not successfully develop and commercialize products based upon our approach orfind suitable and economical sources for materials used in the production of our products, we will not become profitable, which would materially and adversely affect the value of our common stock.

The immuno-oncology industry is also rapidly developing, and our competitorsmay introduce new technologies improving the immune response to cancer that render our technologies obsolete or less attractive. New technology could emerge at any point in the development cycle of our product candidates.

We plan to initiate clinical trials with IO102-IO103 in melanoma and other solid tumors, and our third productcandidate, IO112, targets an immune resistance pathway known as Arginase 1 which is highly expressed in solid cancer indications. If our product candidates do not show any functionality in the solid tumor microenvironment our development plans,financial position, results of operations and prospects may be materially adversely affected.

While we plan todevelop product candidates for use in solid tumors, including IO102-IO103 and IO112, our product candidates may not show any functionality in the solid tumor microenvironment. The cellular environment in which solid tumor cells thrive is generallyhostile to T cells due to factors such as the presence of immunosuppressive cells, humoral factors and limited access to nutrients. Our product candidates may not be able to access the solid tumor, and even if they do, they may not be able to exertanti-tumor effects in a hostile tumor microenvironment. In addition, the safety profile of our product candidates may differ in a solid tumor setting. As a result, our product candidates may not demonstrate efficacy in solid tumors. If we are unableto make our product candidates function in solid tumors, our development plans, financial position, results of operations and prospects may be materially adversely affected.

We may experience delays or difficulties in the enrollment and/or retention of patients in clinical trials, which coulddelay or prevent our receipt of necessary regulatory approvals.

Successful and timely completion of clinicaltrials will require that we enroll a sufficient number of patients. Patient enrollment, which is an important factor in the timing of clinical trials, is affected by many factors, including the size and nature of the patient population andcompetition for patients eligible for our clinical trials with competitors which may have ongoing clinical trials for product candidates that are under development to treat the same indications as one or more of our product candidates, or approvedproducts for the conditions for which we are developing our product candidates.

Trials may be subject to delays as aresult of patient enrollment taking longer than anticipated or patient withdrawal. In particular, enrollment for our upcoming Phase 3 potentially registrational trial may take longer than anticipated due to other monotherapies and combinationtherapies being investigated in the first-line setting at this time. We may not be able to initiate or continue clinical trials for our product candidates if we are unable to locate and enroll a sufficient number of eligible patients to participatein these trials as required by the FDA, EMA, or comparable foreign regulatory authorities. We cannot predict how successful we will be at enrolling subjects in future clinical trials. Subject enrollment is affected by other factors including:

 

  

the severity and difficulty of diagnosing the disease under investigation;

 

  

the eligibility and exclusion criteria for the trial in question;

 

  

the size of the patient population and process for identifying patients;

 

  

our ability to recruit clinical trial investigators with the appropriate competencies and experience;

 

  

the design of the trial protocol;

 

  

the perceived risks and benefits of the product candidate in the trial, including relating to cell therapyapproaches;

 

  

the availability of competing commercially available therapies and other competing therapeuticcandidates’ clinical trials for the disease or condition under investigation, including for melanoma and other cancers in a first-line setting;

 

  

the willingness of patients to be enrolled in our clinical trials;

 

17


Table of Contents
  

the efforts to facilitate timely enrollment in clinical trials;

 

  

potential disruptions caused by the COVID-19 pandemic, includingdifficulties in initiating clinical sites, enrolling and retaining participants, diversion of healthcare resources away from clinical trials, travel or quarantine policies that may be implemented, and other factors;

 

  

the patient referral practices of physicians;

 

  

the ability to monitor patients adequately during and after treatment; and

 

  

the proximity and availability of clinical trial sites for prospective patients.

Our inability to enroll a sufficient number of patients for clinical trials would result in significant delays and couldrequire us to abandon one or more clinical trials altogether. Enrollment delays in these clinical trials may result in increased development costs for our product candidates, which would cause the value of our company to decline and limit ourability to obtain additional financing. Furthermore, we expect to rely on contract research organizations (CROs) and clinical trial sites to ensure the proper and timely conduct of our clinical trials and we will have limited influence over theirperformance.

Interim “top-line” and preliminary results from ourclinical trials that we announce or publish from time to time may change as more patient data become available and are subject to audit and verification procedures that could result in material changes in the final data.

From time to time, we may publish interim top-line or preliminary results from ourclinical trials. Interim results from clinical trials that we may complete are subject to the risk that one or more of the clinical outcomes may materially change as patient enrollment continues and more patient data become available. Preliminary ortop-line results also remain subject to audit and verification procedures that may result in the final data being materially different from the preliminary data we previously published. As a result, interimand preliminary data that we report may differ from future results of the same trials, or different conclusions or considerations may qualify such results, once additional data have been received and fully evaluated, and should be viewed withcaution until the final data are available. Differences between preliminary or interim data and final data could significantly harm our business prospects and may cause the trading price of our common stock to fluctuate significantly.

The regulatory approval processes of the FDA, European Commission (based on recommendation from the EMA), and comparableforeign authorities are lengthy, time consuming and inherently unpredictable. if we are not able to obtain required regulatory approval for our product candidates, our business will be substantially harmed.

The time required to obtain approval or other marketing authorizations by the FDA, European Commission (based on recommendationfrom the EMA), and comparable foreign regulatory authorities is unpredictable, and it typically takes many years following the commencement of clinical trials and depends upon numerous factors, including the substantial discretion of the regulatoryauthorities. In addition, approval policies, regulations, and the type and amount of clinical data necessary to gain approval may change during the course of a product candidate’s clinical development and may vary among jurisdictions. We havenot obtained regulatory approval for any product candidate, and it is possible that we may never obtain regulatory approval for any product candidates we may seek to develop in the future. Neither we nor any current or future collaborator ispermitted to market any drug product candidates in the United States until we receive regulatory approval of a biologics license application (BLA) from the FDA, and we cannot market it in the European Union (EU) or United Kingdom (UK) until wereceive a marketing authorization approval (MAA) from the European Commission (based on recommendation from the EMA) or other required regulatory approval in other countries. To date, we have had only limited discussions with the FDA and EuropeanCommission (based on recommendation from the EMA) regarding clinical development programs or regulatory approval for any product candidate within the United States and EU, respectively. In addition, we have had no discussions with other comparableforeign authorities regarding clinical development programs or regulatory approval for any product candidate outside of those jurisdictions.

Prior to obtaining approval to commercialize any drug product candidate inthe United States or abroad, we must demonstrate with evidence from well-controlled clinical trials, and to the satisfaction of the FDA, European Commission (based on recommendation from the EMA), or other foreign regulatory authorities, that suchproduct candidates are safe and effective for their intended uses. Results from preclinical studies and clinical trials can be interpreted in different ways. Even if we believe the preclinical or clinical data for our product candidates arepromising, such data may not be sufficient to support approval by the FDA, the European Commission (based on recommendation of the EMA), and other comparable foreign regulatory authorities. The FDA or European Commission (based on recommendationfrom the EMA) may also require us to conduct additional preclinical studies or clinical trials for our product candidates either prior to or after approval, or it may object to elements of our clinical development programs.

Our product candidates could fail to receive regulatory approval for many reasons, including the following:

 

  

the FDA, EMA, or comparable foreign regulatory authorities may disagree with the design or implementation ofour clinical trials, or with our interpretation of clinical trial results;

 

  

we may be unable to demonstrate to the satisfaction of the FDA, EMA, or comparable foreign regulatoryauthorities that a product candidate is safe and effective for its proposed indication;

 

  

the results of clinical trials may not meet the level of statistical significance required by the FDA,European Commission (based on recommendation from the EMA), or comparable foreign regulatory authorities for approval;

 

  

we may be unable to demonstrate that a product candidate’s clinical and other benefits outweigh itssafety risks;

 

  

the FDA, European Commission (based on recommendation from the EMA), or comparable foreign regulatoryauthorities may fail to approve the manufacturing processes or facilities of third-party manufacturers with which we contract for clinical and commercial supplies; and

 

  

the approval policies or regulations of the FDA, European Commission EMA, or comparable foreign authoritiesmay significantly change in a manner rendering our clinical data insufficient for approval.

Of thelarge number of products in development, only a small percentage successfully complete the FDA, European Commission (based on recommendation from the EMA), or foreign regulatory approval processes and are commercialized. The lengthy approval andmarketing authorization process as well as the unpredictability of future clinical trial results may result in our failing to obtain regulatory approval and marketing authorization to market our product candidates, which would significantly harm ourbusiness, financial condition, results of operations and prospects.

In the EU, EMA’s Committee for AdvancedTherapies, (CAT), is responsible for assessing the quality, safety, and efficacy of advanced therapy medicinal products (ATMPs). ATMPs include gene therapy medicines, somatic-cell therapy medicines and tissue-engineered medicines. The role of theCAT is to prepare a draft opinion on an application for marketing authorization for a gene therapy medicinal candidate that is submitted to EMA’s Committee for Medicinal Products for Human Use (CHMP) for final adoption. In the EU, thedevelopment and evaluation of ATMPs follow relevant EU guidelines. European Commission or EMA may issue new guidelines concerning the development and marketing authorization for ATMPs and require that we comply with these new guidelines.

We have invested a significant portion of our time and financial resources in the development of our clinical and preclinicalproduct candidates. Our business is dependent on our ability to successfully complete preclinical and clinical development of, obtain regulatory approval for, and, if approved, successfully commercialize IO102-IO103, IO112 and any future productcandidates in a timely manner.

Even if we eventually complete clinical testing and receive approval of a BLA or othercomparable foreign marketing application for IO102-IO103, IO112 or any future product candidates, the FDA, European Commission (based on recommendation from the EMA) or other comparable foreign regulatory authorities may

Table of Contents

grant approval or other marketing authorization contingent on the performance of costly additional clinical trials, including post-marketing clinical trials. The FDA, European Commission (basedon recommendation from the EMA) or other comparable foreign regulatory authorities may also approve or authorize for marketing a product candidate for a more limited indication or patient population than we originally request, and the FDA, EuropeanCommission (based on recommendation from the EMA) or other comparable foreign regulatory authorities may not approve or authorize the labeling that we believe is necessary or desirable for the successful commercialization of a product candidate. Anydelay in obtaining, or inability to obtain, applicable regulatory approval or other marketing authorization would delay or prevent commercialization of that product candidate and would materially adversely impact our business and prospects.

In addition, the FDA, European Commission (based on recommendation from the EMA), or other comparable foreign regulatoryauthorities and regulatory review committees described above may change their policies, issue additional regulations or revise existing regulations, or take other actions, which may prevent or delay approval of our future products under developmenton a timely basis. Such policy or regulatory changes could impose additional requirements upon us that could delay our ability to obtain approvals, increase the costs of compliance or restrict our ability to maintain any marketing authorizations wemay have obtained.

Our preclinical studies and clinical trials may fail to demonstrate the safety and efficacy ofour product candidates, or serious adverse or unacceptable side effects may be identified during the development of our product candidates, which could prevent, delay or limit the scope of regulatory approval of our product candidates, limit theircommercialization, increase our costs or necessitate the abandonment or limitation of the development of some of our product candidates.

To obtain the requisite regulatory approvals for the commercial sale of our product candidates, we must demonstrate throughlengthy, complex and expensive preclinical testing and clinical trials that our product candidates are safe and effective for use in each target indication. These trials are expensive and time consuming, and their outcomes are inherently uncertain.Failures can occur at any time during the development process. Preclinical studies and clinical trials often fail to demonstrate safety or efficacy of the product candidate studied for the target indication, and most product candidates that beginclinical trials are never approved.

We may fail to demonstrate with evidence from adequate and well-controlled trials,and to the satisfaction of the FDA, European Commission (based on recommendation from the EMA), or comparable foreign regulatory authorities, that our product candidates are safe and effective for their intended uses.

Possible adverse reactions and adverse side effects that could occur with immuno-oncology treatments can be severe. Forexample, we have reported to FDA some serious and unexpected suspected adverse reactions from the IO102-112 trial to FDA, which involved pulmonary tuberculosis, enterocolitis, hypovolaemic shock, and diabeticketoacidosis. Depending on an evaluation of the available data, we may decide or be required to perform additional preclinical studies or to halt or delay further clinical development of our product candidates or to limit their development to morenarrow uses or subpopulations in which the undesirable side effects or other characteristics are less prevalent, less severe, or more acceptable from a risk-benefit perspective, which may limit the commercial expectations for the product candidate,if approved.

Our clinical trials could also be suspended or terminated and the FDA, EMA, or comparable foreign regulatoryauthorities could order us to cease further development of, or deny approval of, our product candidates for any or all targeted indications. Even if this does not occur, reports of serious reactions could affect patient recruitment or the ability ofenrolled patients to complete the trial. Moreover, if we elect, or are required, to not initiate, delay, suspend or terminate any future clinical trial of any of our product candidates, the commercial prospects of such product candidates may beharmed and our ability to generate product revenues from any of these product candidates may be delayed or eliminated. Any of these occurrences may harm our ability to develop other product candidates, and may harm our business, financial conditionand prospects significantly.

Table of Contents

If our product candidates are associated with side effects in clinicaltrials or have characteristics that are unexpected, we may need to abandon their development or limit development to more narrow uses in which the side effects or other characteristics are less prevalent, less severe or more acceptable from arisk-benefit perspective. The FDA, EMA, an institutional review board (IRB)/ethics committee (EC), which are local institutional boards or committees, as applicable, that review, approve and oversee basic and clinical research conducted as theinstitution participating in the clinical trial, or comparable foreign regulatory authorities, may also require that we suspend, discontinue, or limit our clinical trials based on safety information, or that we conduct additional animal or humanstudies regarding the safety and efficacy of our product candidates which we have not planned or anticipated. Such findings could further result in regulatory authorities failing to provide marketing authorization for our product candidates orlimiting the scope of the approved indication, if approved. Many product candidates that initially showed promise in early stage testing have later been found to cause side effects that prevented further development of the product candidate.

As an organization, we have never conducted pivotal clinical trials, and we may be unable to do so for any productcandidates we may develop.

We will need to successfully complete clinical trials meeting requirements for approvalof the FDA or comparable foreign regulatory authorities, known as pivotal trials, to market IO102-IO103, IO112, or any future product candidate. Carrying out pivotal clinical trials is a complicated process. As an organization, we have notpreviously conducted any later stage or pivotal clinical trials. In order to do so, we will need to expand our clinical development and regulatory capabilities, and we may be unable to recruit and train qualified personnel. We also expect tocontinue to rely on third parties to conduct our pivotal clinical trials. Consequently, we may be unable to successfully and efficiently execute and complete necessary clinical trials in a way that leads to BLA submission and approval ofIO102-IO103, IO112, or future product candidates. We may require more time and incur greater costs than our competitors and may not succeed in obtaining regulatory approvals of product candidates that we develop. Failure to commence or complete, ordelays in, our planned clinical trials, could prevent us from or delay us in commercializing our product candidates.

Some data for product candidates comes from clinical trials conducted outside the United States, EU and the UK, and theFDA, EMA, or comparable foreign regulatory authorities may not accept data from such trials.

Although we believethat the patient population in the phase 1/2 trial with IO102-IO103 in combination with an anti-PD-1 monoclonal antibody in 30 metastatic melanoma patients is representative of the population for which we intend to label our IO102-103 productcandidate in the United States, the trial was conducted in Europe, and we may conduct additional trials in the future outside of the United States, Europe and the UK. The acceptance of data from clinical trials conducted outside the United States oranother jurisdiction by the FDA may be subject to certain conditions or may not be accepted at all. Similarly, the EMA, and other equivalent foreign regulatory authorities may not accept data from trials conducted outside their jurisdiction. Incases where data from foreign clinical trials are intended to serve as the basis for marketing approval in the United States, the FDA will generally not approve the application on the basis of foreign data alone unless (i) the data areapplicable to the U.S. population and U.S. medical practice; and (ii) the trials were performed by clinical investigators of recognized competence and pursuant to good clinical practice (GCP) regulations. In general, the patient population forany clinical trials conducted outside the United States must be representative of the population for whom we intend to label the product candidate in the United States. Additionally, the FDA’s clinical trial requirements, including sufficientsize of patient populations and statistical powering, must be met. Many foreign regulatory authorities have similar approval requirements for clinical trials. In addition, such trials would be subject to the applicable local laws of the foreignjurisdictions where the trials are conducted. There can be no assurance that the FDA, EMA, or any comparable foreign regulatory authority will accept data from trials conducted outside of the applicable jurisdiction. If the FDA, EMA, or anycomparable foreign regulatory authority does not accept such data, it would result in the need for additional trials, which could be costly and time-consuming, and which may result in product candidates that we may develop not receiving approval forcommercialization in the applicable jurisdiction.

Breakthrough therapy designation by the FDA for any product candidatemay not lead to a faster development or regulatory review or approval process, and it does not increase the likelihood that the product candidate will receive marketing approval

IO102-IO103 combined with an anti-PD-1monoclonal antibody in first line metastatic melanoma patients has been granted breakthrough therapy designation from the FDA. We may also, in the future, apply for breakthrough therapy designation, or the equivalent thereof in foreign jurisdictions(where available), for our product candidates or programs. A breakthrough therapy is defined as a product candidate that is intended, alone or in combination with one or more other drugs, to treat a serious or life-threatening disease or condition,and preliminary clinical evidence indicates that the product candidate may demonstrate substantial improvement over existing therapies on one or more clinically significant endpoints, such as substantial treatment effects observed early in clinicaldevelopment. For product candidates that have been designated as breakthrough therapies, interaction and communication between the FDA and the sponsor of the trial can help to identify the most efficient path for clinical development whileminimizing the number of patients placed in ineffective control regimens. Product candidates designated as breakthrough therapies by the FDA are also eligible for priority review if supported by clinical data at the time of the submission of theBLA.

Designation as a breakthrough therapy is within the discretion of the FDA. Accordingly, even if we believe that oneof our product candidates meets the criteria for designation as a breakthrough therapy, the FDA may disagree and instead determine not to make such designation. In any event, the receipt of a breakthrough therapy designation for a product candidate,including the breakthrough therapy designation of IO102-IO103 combined with an anti-PD-1 monoclonal antibody in first line metastatic melanoma patients, may not resultin a faster development process, review or approval compared to product candidates considered for approval under conventional FDA procedures and it would not assure ultimate approval by the FDA. In addition, even after a product candidate qualifiesas a breakthrough therapy, the FDA may later decide that the product candidate no longer meets the conditions for qualification or it may decide that the time period for FDA review or approval will not be shortened.

Even if we receive regulatory approval for any of our product candidates, we will be subject to ongoing regulatoryobligations and continued regulatory review, which may result in significant additional expense. Additionally, our product candidates, if approved, could be subject to post-market study requirements, marketing and labeling restrictions, and evenrecall or market withdrawal if unanticipated safety issues are discovered following approval. In addition, we may be subject to penalties or other enforcement action if we fail to comply with regulatory requirements.

If the FDA, the European Commission (based on recommendation from the EMA), or a comparable foreign regulatory authorityapproves any of our product candidates, the manufacturing processes, labeling, packaging, distribution, storage, advertising, promotion, import, export, recordkeeping, monitoring, and reporting for our product will be subject to extensive andongoing regulatory requirements. These requirements include submissions of safety and other post-marketing information and reports, establishment registration and listing, as well as continued compliance with current Good Manufacturing Practicerequirements (cGMPs) and GCP requirements for any clinical trials that we conduct post-approval. Any regulatory approvals that we receive for our product candidates may also be subject to limitations on the approved indicated uses for which theproduct may be marketed or to the conditions of approval, or contain requirements for potentially costly post-marketing studies, including Phase 4 clinical trials, and surveillance to monitor the safety and efficacy of the product.

The FDA may require a risk evaluation and mitigation strategy (REMS) in order to approve our product candidates, which couldentail requirements for a medication guide, physician communication plans or additional elements to ensure safe use, such as restricted distribution methods, patient registries and other risk minimization tools. Later discovery of previously unknownproblems with a product, including adverse events of unanticipated severity or frequency, or with our third-party manufacturers or manufacturing processes, or failure to comply with regulatory requirements, may result in, among other things:

 

  

restrictions on the marketing or manufacturing of the product, withdrawal of the product from the market, orvoluntary or mandatory product recalls;

 

22


Table of Contents
  

revision to the labeling, including limitations on approved uses or the addition of additional warnings,contraindications or other safety information, including boxed warnings;

 

  

imposition of a REMS, which may include distribution or use restrictions;

 

  

requirements to conduct additional post-market clinical trials to assess the safety of the product;

 

  

fines, warning letters or other regulatory enforcement action;

 

  

refusal by the FDA to approve pending applications or supplements to approved applications filed by us;

 

  

product seizure or detention, or refusal to permit the import or export of products; and

 

  

injunctions or the imposition of civil or criminal penalties;

In the EU, the European Commission (based on recommendation from the EMA) may require an equivalent risk management plan(RMP). The FDA’s, European Commission’s, EMA’s, and other comparable foreign regulatory authorities’ policies may change and additional government regulations may be enacted that could prevent, limit or delay regulatory approvalof our product candidates. If we are slow or unable to adapt to changes in existing requirements or the adoption of new requirements or policies, or if we are not able to maintain regulatory compliance, we may lose any marketing approval that we mayhave obtained, which would adversely affect our business, prospects and ability to achieve or sustain profitability.

We anticipate that our current product candidates and any future product candidates will be used in combination withthird-party drugs or biologics, some of which are still in development, and we have limited or no control over the supply, regulatory status, or regulatory approval of such drugs or biologics.

Our T-win technology targets both immune suppressive host and tumor cells in the TMEinitiating a dynamic process of activating the host immune system, which response can be further exploited by concurrent or subsequent therapies as checkpoint inhibitors such as the dominant PD-1 monoclonalantibodies, pembrolizumab and nivolumab. Accordingly, it is expected that our product candidates, if approved, would be used in combination with third-party drugs or biologics. For example, IO102-IO103 in combination with an anti-PD-1 monoclonal antibody was recently investigated in a Phase 1/2 trial in 30 metastatic melanoma patients at University Hospital of Copenhagen, and we are planning aPhase 3 clinical trial, the IOB-013/KN-D18 trial, combining IO102-IO103 with an pembrolizumab in first line advanced melanoma patients. Our ability to develop and ultimately commercialize our current product candidates and any future productcandidates used in combination with pembrolizumab, nivolumab, or any other checkpoint inhibitor immunotherapies will depend on our ability to access such drugs or biologics on commercially reasonable terms for the clinical trials and theiravailability for use with the commercialized product, if approved. We cannot be certain that current or potential future commercial relationships will provide us with a steady supply of such drugs or biologics on commercially reasonable terms or atall.

Any failure to maintain or enter into new successful commercial relationships, or the expense of purchasingcheckpoint inhibitor immunotherapies or other comparator therapies in the market, may delay our development timelines, increase our costs and jeopardize our ability to develop our current product candidates and any future product candidates ascommercially viable therapies. If any of these occur, our business, financial condition, results of operations, stock price and prospects may be materially harmed.

Moreover, the development of product candidates for use in combination with another product or product candidate may presentchallenges that are not faced for single agent product candidates. We are currently developing IO102-IO103 and IO112 and may develop other future product candidates for use in combination with checkpoint inhibitors and may develop IO102-IO103 andIO112, or any future product candidates for use with other therapies. The FDA, EMA, or comparable foreign regulatory authorities may require us to use more complex clinical trial designs in order to evaluate the contribution of each product andproduct candidate to any observed effects. It is possible that the results of such trials could show that any positive previous trial results are

 

23


Table of Contents

attributable to the combination therapy and not our current product candidates and any future product candidates. It is also possible that trial results for our product candidates may differsignificantly if our product candidates are investigated with different combination therapies in different trials - for example, if we were to investigate our product candidates with one anti-PD-1 monoclonal antibody in one trial and a differentanti-PD-1 monoclonal antibody in another. Moreover, following product approval, the FDA, EMA, or comparable foreign regulatory authorities may require that products used in conjunction with each other be cross labeled for combined use. To the extentthat we do not have rights to the other product, this may require us to work with a third party to satisfy such a requirement. Moreover, developments related to the other product may impact our clinical trials for the combination as well as ourcommercial prospects should we receive marketing approval. Such developments may include changes to the other product’s safety or efficacy profile, changes to the availability of the approved product, quality, manufacturing and supply issues,and changes to the standard of care.

In the event that any of our collaborators or suppliers cannot continue to supplytheir products on commercially reasonable terms, we would need to identify alternatives for accessing such checkpoint inhibitor immunotherapies. Additionally, should the supply of products from any collaborator or supplier be interrupted, delayed orotherwise be unavailable to us, our clinical trials may be delayed. In the event we are unable to source an alternative supply, or are unable to do so on commercially reasonable terms, our business, financial condition, results of operations, stockprice and prospects may be materially harmed.

We may expend our limited resources to pursue a particular productcandidate or indication and fail to capitalize on product candidates or indications that may be more profitable or for which there is a greater likelihood of success.

Because we have limited financial and managerial resources, we must prioritize our research programs and will need to focus ourdiscovery and development on select product candidates and indications. Correctly prioritizing our research and development activities is particularly important for us due to the breadth of potential product candidates and indications that webelieve could be pursued using our platform technologies. As a result, we may forego or delay pursuit of opportunities with other product candidates or for other indications that later prove to have greater commercial potential. Our resourceallocation decisions may cause us to fail to capitalize on viable commercial products or profitable market opportunities. Our spending on current and future research and development programs and product candidates for specific indications may notyield any commercially viable products. If we do not accurately evaluate the commercial potential or target market for a particular product candidate, we may also relinquish valuable rights to that product candidate through collaboration, licensingor other royalty arrangements in cases in which it would have been more advantageous for us to retain sole development and commercialization rights to such product candidate.

If we fail to develop additional product candidates, our commercial opportunity could be limited.

We expect initially to focus on the development of our lead dual epitope IO102-IO103, as well as our third product candidate,IO112. A key part of our strategy, however, is to continue to pursue clinical development of additional product candidates utilizing our T-win technology platform. Developing, obtaining marketing approval for,and commercializing any future product candidates will require substantial additional funding beyond the net proceeds of this offering and will be subject to the risks of failure inherent in drug product development. We cannot assure you that wewill be able to successfully advance any future product candidates through the development process.

Even if we obtainapproval from the FDA, European Commission (based on recommendation from the EMA) or comparable foreign regulatory authorities to market any future product candidates for the treatment of tumors, we cannot assure that any such product candidateswill be successfully commercialized, widely accepted in the marketplace, or more effective than other commercially available alternatives. If we are unable to successfully develop and commercialize additional product candidates our commercialopportunity may be limited and our business, financial condition, results of operations, stock price and prospects may be materially harmed.

Difficulty in enrolling patients could delay or prevent clinical trials ofour current product candidates and any future product candidates. We may find it difficult to enroll patients in our ongoing clinical trials or any subsequent trials we may conduct and our receipt of necessary regulatory approvals could be delayedor prevented.

Identifying and qualifying patients to participate in clinical studies of our current product candidatesand any future product candidates is critical to our success. The timing of completion of our clinical trials depends in part on the speed at which we can recruit patients to participate in testing our current product candidates and any futureproduct candidates, and we may experience delays in our clinical trials if we encounter difficulties in enrollment or patient retention due to other unforeseen factors. We may not be able to initiate or continue clinical trials for our currentproduct candidates and any future product candidates if we are unable to locate and enroll and retain a sufficient number of eligible patients to participate in these trials as required by the FDA, EMA, or comparable foreign regulatory authoritiesoutside the United States. For example, the COVID-19 pandemic may impact our ability to initiate clinical sites and recruit, enroll and retain patients or may divert healthcare resources away from clinicaltrials. In addition, some of our competitors have ongoing clinical trials for product candidates that treat the same indications as our current product candidates, and patients who would otherwise be eligible for our clinical trials may insteadenroll in clinical trials of our competitors’ product candidates or future product candidates.

In addition to thecompetitive trial environment, the eligibility criteria of our planned clinical trials will further limit the pool of available study participants as we will require that patients have specific characteristics that we can measure to assure theircancer is either severe enough or not too advanced to include them in a study. Additionally, the process of finding patients may prove costly. We also may not be able to identify, recruit and enroll a sufficient number of patients to complete ourclinical studies because of the perceived risks and benefits of the product candidates under study, the availability and efficacy of competing therapies and clinical trials, the proximity and availability of clinical trial sites for prospectivepatients, and the patient referral practices of physicians. If patients are unwilling to participate in our studies for any reason, the timeline for recruiting patients, conducting studies and obtaining regulatory approval of potential products maybe delayed.

The enrollment of patients further depends on many factors, including:

 

  

the size of the patient population and process for identifying patients;

 

  

the eligibility criteria for the clinical trial in question;

 

  

the availability of an appropriate screening test, as necessary;

 

  

the perceived risks and benefits of the product candidate under study;

 

  

the efforts to facilitate timely enrollment in clinical trials;

 

  

the proximity and availability of clinical trial sites for prospective patients;

 

  

the design of the clinical trial;

 

  

our ability to recruit clinical trial investigators with the appropriate competencies and experience;

 

  

our ability to obtain and maintain patient consents;

 

  

reporting of the preliminary results of any of our clinical trials; and

 

  

the risk that patients enrolled in clinical trials will drop out of the clinical trials before clinical trialcompletion.

In addition, our clinical trials will compete with other clinical trials for productcandidates that are in the same therapeutic areas as our current product candidates and any future product candidates, and this competition

will reduce the number and types of patients available to us because some patients who might have opted to enroll in our clinical trials may instead opt to enroll in a clinical trial beingconducted by one of our competitors. Since the number of qualified clinical investigators is limited, we expect to conduct some of our clinical trials at the same clinical trial sites that some of our competitors use, which will reduce the number ofpatients who are available for our clinical trials at such clinical trial sites. Furthermore, even if we are able to enroll a sufficient number of patients for our clinical trials, we may have difficulty maintaining enrollment of such patients inour clinical trials.

If we experience delays in the completion of, or termination of, any clinical trial of our currentproduct candidates and any future product candidates, the commercial prospects of our current product candidates and any future product candidates will be harmed, and our ability to generate product revenue from such product candidates could bedelayed or prevented.

Our future growth depends, in part, on our ability to penetrate multiple markets in which wewould be subject to additional regulatory burdens and other risks and uncertainties.

Our future profitability willdepend, in part, on our ability to continue to commercialize our products and, if approved, our product candidates, in markets in the United States, Europe , the UK, and other countries where we maintain commercialization rights. As we continue tocommercialize our products and begin to commercialize our product candidates, if approved, in multiple markets, we are subject to additional risks and uncertainties, including:

 

  

foreign currency exchange rate fluctuations and currency controls;

 

  

economic weakness, including inflation, or political instability in particular economies and markets;

 

  

uncertainties related to Brexit, including potential impacts on costs, exchange rates, flow of goods,manufacturing and operations;

 

  

potentially adverse and/or unexpected tax consequences, including penalties due to the failure of tax planningor due to the challenge by tax authorities on the basis of transfer pricing and liabilities imposed from inconsistent enforcement;

 

  

the burden of complying with complex and changing regulatory, tax, accounting and legal requirements, many ofwhich vary between countries;

 

  

different medical practices and customs in multiple countries affecting acceptance of drugs in themarketplace;

 

  

differing payor reimbursement regimes, governmental payors orpatient self-pay systems and price controls;

 

  

tariffs, trade barriers, import or export licensing requirements or other restrictive actions;

 

  

compliance with tax, employment, immigration and labor laws for employees living or traveling abroad;

 

  

workforce uncertainty in countries where labor unrest is common;

 

  

reduced or loss of protection of intellectual property rights in some foreign countries, and relatedprevalence of generic alternatives to therapeutics; and

 

  

becoming subject to the different, complex and changing laws, regulations and court systems of multiplejurisdictions and compliance with a wide variety of foreign laws, treaties and regulations.

These andother risks associated with international operations may adversely affect our ability to attain or maintain profitable operations. Future sales of our products or our product candidates, if they are approved, will be dependent on purchasingdecisions of and reimbursement from government health administration authorities,

distributors and other organizations. As a result of adverse conditions affecting the global economy and credit and financial markets, including disruptions due to political instability orotherwise, these organizations may defer purchases, may be unable to satisfy their purchasing or reimbursement obligations, or may affect milestone payments or royalties for our products or any of our product candidates that are approved forcommercialization in the future. Should any of these risks materialize, this could have a material adverse effect on our business, prospects, financial condition and results of operations.

Risks Related to Manufacturing and Commercialization

The manufacture of our product candidates is complex and we may encounter difficulties in production, particularly withrespect to process development or scaling-out of our manufacturing capabilities. If we encounter such difficulties, our ability to provide supply of our product candidates for clinical trials or our productsfor patients, if approved, could be delayed or stopped.

We have not yet manufactured or processed our productcandidates on a commercial scale and may not be able to do so for any of our product candidates. We may encounter difficulties in production, particularly in scaling up or out, validating the production process, and assuring high reliability of themanufacturing process. These problems include delays or break-downs in logistics and shipping, difficulties with production costs and yields, quality control, and product testing, operator error, lack of availability of qualified personnel, as wellas failure to comply with strictly enforced federal, state and foreign regulations.

Furthermore, if contaminations arediscovered in our supply of product candidates or in the manufacturing facilities, such manufacturing facilities may need to be closed for an extended period of time to investigate and remedy the contamination. We cannot assure you that any of theseor other issues relating to the manufacture of our product candidates will not occur in the future. Any delay or interruption in the supply of clinical trial supplies could delay the completion of clinical trials, increase the costs associated withmaintaining clinical trial programs and, depending upon the period of delay, require us to begin new clinical trials at additional expense or terminate clinical trials completely.

Manufacturing facilities also require commissioning and validation activities to demonstrate that they operate as designed,and are subject to government inspections by the FDA, EU Member States, coordinated by the EMA, and other comparable foreign regulatory authorities. If we are unable to reliably produce products to specifications acceptable to the regulatoryauthorities, we may not obtain or maintain the approvals we need to manufacture our products. Further, manufacturing facilities may fail to pass government inspections prior to or after the commercial launch of our product candidates, which wouldcause significant delays and additional costs required to remediate any deficiencies identified by the regulatory authorities. Any of these challenges could delay completion of clinical trials, require bridging clinical trials or the repetition ofone or more clinical trials, increase clinical trial costs, delay approval of our product candidate, impair commercialization efforts, increase our cost of goods, and have an adverse effect on our business, financial condition, results of operationsand growth prospects.

Changes in product candidate manufacturing or formulation may result in additional costs ordelay.

As product candidates are developed through preclinical studies to later-stage clinical trials towardsapproval and commercialization, it is common that various aspects of the development program, such as manufacturing methods and formulation, are altered along the way in an effort to optimize processes and results. Any of these changes could causeour current product candidates or any future product candidates to perform differently and affect the results of planned clinical trials or other future clinical trials conducted with the altered materials. Such changes may also require additionaltesting, or notification to, or approval by the FDA, European Commission, EMA, or a comparable foreign regulatory authority. This could delay completion of clinical trials, require the conduct of bridging clinical trials or studies, require therepetition of one or more clinical trials, increase clinical trial costs, delay approval of our current product candidates and any future product candidates and/or jeopardize our ability to commence product sales and generate revenue.

Even if any of our product candidates receives marketing approval, itmay fail to achieve the degree of market acceptance by physicians, patients, third-party payors and others in the medical community necessary for commercial success.

Even if we obtain marketing approvals from the FDA, European Commission (based on recommendation from the EMA), or othercomparable foreign regulatory agencies and are able to initiate commercialization of our clinical-stage product candidates or any other product candidates we develop, the product candidate may not achieve market acceptance among physicians,patients, hospitals, including pharmacy directors, and third-party payors and, ultimately, may not be commercially successful. The degree of market acceptance of our product candidates, if approved for commercial sale, will depend on a number offactors, including:

 

  

the clinical indications for which our product candidates are approved;

 

  

physicians, hospitals, cancer treatment centers, and patients considering our product candidates as a safe andeffective treatment;

 

  

the potential and perceived advantages of our product candidates over alternative treatments;

 

  

the prevalence and severity of any side effects;

 

  

product labeling or product insert requirements of the FDA, European Commission, EMA, or other comparableforeign regulatory authorities;

 

  

limitations or warnings contained in the labeling approved by the FDA, European Commission, EMA, or othercomparable foreign regulatory authorities;

 

  

the timing of market introduction of our product candidates as well as competitive products;

 

  

the cost of treatment in relation to alternative treatments;

 

  

the amount of upfront costs or training required for physicians to administer our product candidates;

 

  

the availability of coverage, adequate reimbursement from, and our ability to negotiate pricing with,third-party payors and government authorities;

 

  

the willingness of patients to payout-of-pocket in the absence of comprehensive coverage and reimbursement by third-party payors and government authorities;

 

  

relative convenience and ease of administration, including as compared to alternative treatments andcompetitive therapies; and

 

  

the effectiveness of our sales and marketing efforts and distribution support.

Our efforts to educate physicians, patients, third-party payors and others in the medical community on the benefits of ourproduct candidates, if approved, may require significant resources and may never be successful. Such efforts may require more resources than are typically required due to the complexity and uniqueness of our product candidates. Because we expectsales of our product candidates, if approved, to generate substantially all of our product revenue for the foreseeable future, the failure of our product candidates to find market acceptance would harm our business and could require us to seekadditional financing. Even if our product candidates, if approved, achieve market acceptance, we may not be able to maintain that market acceptance over time if new products or technologies are introduced that are more favorably received than ourproducts, are more cost effective or render our products obsolete.

We may not be able to successfully commercializeour product candidates, if approved, due to unfavorable pricing regulations or third-party coverage and reimbursement policies, which could make it difficult for us to sell our product candidates profitably

Obtaining coverage and reimbursement approval for a product from a government or other third-party payor is a time-consumingand costly process, with uncertain results, that could require us to provide supporting

scientific, clinical and cost effectiveness data for the use of our products to the payor. There may be significant delays in obtaining such coverage and reimbursement for newly approvedproducts, and coverage may not be available, or may be more limited than the purposes for which the product is approved by the FDA or other comparable foreign regulatory authorities. Moreover, eligibility for coverage and reimbursement does notimply that a product will be paid for in all cases or at a rate that covers our costs, including research, development, intellectual property, manufacture, sale and distribution expenses. Interim reimbursement levels for new products, if applicable,may also not be sufficient to cover our costs and may not be made permanent. Reimbursement rates may vary according to the use of the product and the clinical setting in which it is used, may be based on reimbursement levels already set for lowercost products and may be incorporated into existing payments for other services. Net prices for products may be reduced by mandatory discounts or rebates required by government healthcare programs or private payors, by any future laws limiting drugprices and by any future relaxation of laws that presently restrict imports of product from countries where they may be sold at lower prices than in the United States.

There is significant uncertainty related to the insurance coverage and reimbursement of newly approved products. In the UnitedStates, there is no uniform policy among third-party payors for coverage and reimbursement. Third-party payors often rely upon Medicare coverage policy and payment limitations in setting reimbursement policies, but also have their own methods andapproval process apart from Medicare coverage and reimbursement determinations. Therefore, one third-party payor’s determination to provide coverage for a product does not assure that other payors will also provide coverage for the product.

Coverage and reimbursement by a third-party payor may depend upon a number of factors, including the third-partypayor’s determination that use of a product is:

 

  

a covered benefit under its health plan;

 

  

safe, effective and medically necessary;

 

  

appropriate for the specific patient;

 

  

cost-effective; and

 

  

neither experimental nor investigational.

We cannot be sure that reimbursement will be available for any product that we commercialize and, if coverage andreimbursement are available, what the level of reimbursement will be. Our inability to promptly obtain coverage and adequate reimbursement rates from both government-funded and private payors for any approved products that we develop could have amaterial adverse effect on our operating results, our ability to raise capital needed to commercialize products and our overall financial condition.

Reimbursement may impact the demand for, and the price of, any product for which we obtain marketing approval. Even if weobtain coverage for a given product by a third-party payor, the resulting reimbursement payment rates may not be adequate or may require co-payments that patients find unacceptably high. Patients who areprescribed medications for the treatment of their conditions, and their prescribing physicians, generally rely on third-party payors to reimburse all or part of the costs associated with those medications. Patients are unlikely to use our productsunless coverage is provided and reimbursement is adequate to cover all or a significant portion of the cost of our products. Therefore, coverage and adequate reimbursement are critical to a new product’s acceptance. Coverage decisions maydepend upon clinical and economic standards that disfavor new products when more established or lower cost therapeutic alternatives are already available or subsequently become available.

For products administered under the supervision of a physician, obtaining coverage and adequate reimbursement may beparticularly difficult because of the higher prices often associated with such drugs. Additionally, separate reimbursement for the product itself may or may not be available. Instead, the hospital or

 

29


Table of Contents

administering physician may be reimbursed only for providing the treatment or procedure in which our product is used. Further, from time to time, the Centers for Medicare & MedicaidServices (CMS), the federal agency responsible for administering the Medicare program, revises the reimbursement amounts paid to health care providers, including the Medicare Physician Fee Schedule and Hospital Outpatient Prospective Payment System,which may result in reduced Medicare payments.

We expect to experience pricing pressures in connection with the sale ofany of our product candidates due to the trend toward managed healthcare, the increasing influence of health maintenance organizations, and additional legislative changes. The downward pressure on healthcare costs in general, particularlyprescription medicines, medical devices and surgical procedures and other treatments, has become very intense. As a result, increasingly high barriers are being erected to the successful commercialization of new products. Further, the adoption andimplementation of any future governmental cost containment or other health reform initiative may result in additional downward pressure on the price that we may receive for any approved product.

Outside of the United States, many countries require approval of the sale price of a product before it can be marketed, andthe pricing review period only begins after marketing or product licensing approval is granted. To obtain reimbursement or pricing approval in some of these countries, we may be required to conduct a clinical trial that compares thecost-effectiveness of our product candidate to other available therapies. In some foreign markets, prescription pharmaceutical pricing remains subject to continuing governmental control even after initial approval is granted. As a result, we mightobtain marketing approval for a product candidate in a particular country, but then be subject to price regulations that delay our commercial launch of the product, possibly for lengthy time periods, and negatively impact the revenue, if any, we areable to generate from the sale of the product in that country. Adverse pricing limitations may hinder our ability to recoup our investment in one or more product candidates, even if such product candidates obtain marketing approval.

Reimbursement and healthcare payment systems vary significantly by country outside the US, and many countries have institutedprice ceilings on specific products and therapies. In the EU and the UK, similar political, economic and regulatory developments may affect our ability to profitably commercialize our product candidates, if approved. In addition to continuingpressure on prices and cost containment measures, legislative developments at the EU, UK or at a EU Member State level may result in significant additional requirements or obstacles that may increase our operating costs. The delivery of healthcarein the EU and the UK, including the establishment and operation of health services and the pricing and reimbursement of medicines, is almost exclusively a matter for national, rather than EU, law and policy. National governments and health serviceproviders have different priorities and approaches to the delivery of health care and the pricing and reimbursement of products in that context. In general, however, the healthcare budgetary constraints in most EU Member States and the UK haveresulted in restrictions on the pricing and reimbursement of medicines by relevant health service providers. Coupled with ever-increasing EU and national regulatory burdens on those wishing to develop and market products in these countries, thiscould prevent or delay marketing approval of our product candidates, restrict or regulate post-approval activities and affect our ability to commercialize our product candidates, if approved.

We cannot predict the likelihood, nature or extent of government regulation that may arise from future legislation oradministrative action in the US, the EU, UK or any other jurisdiction. If we, or any third parties we may engage are slow or unable to adapt to changes in existing requirements or the adoption of new requirements or policies, or if we or such thirdparties are not able to maintain regulatory compliance, our product candidates may lose any regulatory approval that may have been obtained and we may not achieve or sustain profitability.

If the regulatory authorities in such jurisdictions set prices or make reimbursement criteria that are not commerciallyattractive for us or our collaborators, our revenues and the potential profitability of our products in those countries would be negatively affected.

If the market opportunities for any of our product candidates aresmaller than we believe they are, our revenue may be adversely affected, and our business may suffer.

We arefocused on the development of treatments for cancer. Our projections of addressable patient populations that have the potential to benefit from treatment with our product candidates are based on estimates, including estimated incidence rates ofspecific forms of cancer. If any of our estimates are inaccurate, the market opportunities for any of our product candidates could be significantly diminished and have an adverse material impact on our business.

If any of our product candidates are approved for marketing and commercialization and we are unable to establish salesand marketing capabilities or enter into agreements with third parties to sell and market our product candidates, we will be unable to successfully commercialize our product candidates if and when they are approved.

We have no sales, marketing or distribution capabilities or experience. To achieve commercial success for any approved productfor which we retain sales and marketing responsibilities, we must either develop a sales and marketing organization, which would be expensive and time consuming, or outsource these functions to other third parties. In the future, we may choose tobuild a focused sales and marketing infrastructure to sell, or participate in sales activities with our collaborators for, some of our product candidates if and when they are approved.

There are risks involved with both establishing our own sales and marketing capabilities and entering into arrangements withthird parties to perform these services. For example, recruiting and training a sales force is expensive and time consuming and could delay any product launch. If the commercial launch of a product candidate for which we recruit a sales force andestablish marketing capabilities is delayed or does not occur for any reason, we would have prematurely or unnecessarily incurred these commercialization expenses. This may be costly, and our investment would be lost if we cannot retain orreposition our sales and marketing personnel. Factors that may inhibit our efforts to commercialize future products on our own include:

 

  

our inability to recruit and retain adequate numbers of effective sales and marketing personnel;

 

  

the inability of sales personnel to compliantly obtain access to physicians or educate adequate numbers ofphysicians on the benefits of prescribing any future products;

 

  

the lack of complementary products to be offered by sales personnel, which may put us at a competitivedisadvantage relative to companies with more extensive product portfolios; and

 

  

unforeseen costs and expenses associated with creating an independent sales and marketing organization.

If we enter into arrangements with third parties to perform sales, marketing and distribution services,our product revenue or the profitability of these product revenue to us are likely to be lower than if we were to market and sell any products that we develop ourselves. In addition, we may not be successful in entering into arrangements with thirdparties to sell and market our product candidates or may be unable to do so on terms that are favorable to us. In entering into third-party marketing or distribution arrangements, any revenue we receive will depend upon the efforts of the thirdparties and we cannot assure you that such third parties will establish adequate sales and distribution capabilities or devote the necessary resources and attention to sell and market any future products effectively. If we do not establish sales andmarketing capabilities successfully, either on our own or in collaboration with third parties, we will not be successful in commercializing our product candidates.

Regulatory approval by the FDA, European Commission (based onrecommendation from the EMA) or comparable foreign regulatory authorities is limited to those specific indications and conditions for which approval has been granted, and we may be subject to substantial fines, criminal penalties, injunctions, orother enforcement actions if we are determined to be promoting the use of our products for unapproved or “off-label” uses, or in a manner inconsistent with the approved labeling, resulting in damageto our reputation and business.

We must comply with requirements concerning advertising and promotion for anyproduct candidates for which we obtain marketing approval. Promotional communications with respect to therapeutics are subject to a variety of legal and regulatory restrictions and continuing review by the FDA or comparable foreign regulatory andgovernmental authorities, Department of Justice, Department of Health and Human Services’ (HHS) Office of Inspector General, state attorneys general, members of Congress, and the public. When the FDA or comparable foreign regulatory authoritiesissue regulatory approval for a product candidate, the regulatory approval is limited to those specific uses and indications for which a product is approved. If we are not able to obtain FDA or comparable foreign regulatory authority approval fordesired uses or indications for our current product candidates and any future product candidates, we may not market or promote them for those indications and uses, referred to as off-label uses, and ourbusiness, financial condition, results of operations, stock price and prospects will be materially harmed. We also must sufficiently substantiate any claims that we make for our products, including claims comparing our products to othercompanies’ products, and must abide by the FDA or a comparable foreign regulatory or governmental authority’s strict requirements regarding the content of promotion and advertising.

While physicians may choose to prescribe products for uses that are not described in the product’s labeling and for usesthat differ from those tested in clinical trials and approved by the regulatory authorities, we and any third parties engaged on our behalf are prohibited from marketing and promoting the products for indications and uses that are not specificallyapproved by the FDA or comparable foreign regulatory authorities. Regulatory authorities in the United States generally do not restrict or regulate the behavior of physicians in their choice of treatment within the practice of medicine. Regulatoryauthorities do, however, restrict communications by biopharmaceutical companies concerning off-label use.

If we are found to have impermissibly promoted any of our current product candidates and any future product candidates, we maybecome subject to significant liability and government fines. The FDA and other agencies actively enforce the laws and regulations regarding product promotion, particularly those prohibiting the promotion ofoff-label uses, and a company that is found to have improperly promoted a product may be subject to significant sanctions. The federal government has levied large civil and criminal fines against companies foralleged improper promotion and has enjoined several companies from engaging in off-label promotion. The FDA has also requested that companies enter into consent decrees or permanent injunctions under whichspecified promotional conduct is changed or curtailed.

In the United States, engaging in the impermissible promotion ofour products, following approval, for off-label uses can also subject us to false claims and other litigation under federal and state statutes. These include fraud and abuse and consumer protection laws, whichcan lead to civil and criminal penalties and fines, agreements with governmental authorities that materially restrict the manner in which we promote or distribute therapeutic products and conduct our business. These restrictions could includecorporate integrity agreements, suspension or exclusion from participation in federal and state healthcare programs, and suspension and debarment from government contracts and refusal of orders under existing government contracts. These False ClaimsAct lawsuits against manufacturers of drugs and biologics have increased significantly in volume and breadth, leading to several substantial civil and criminal settlements pertaining to certain sales practices and promoting off-label uses. In addition, False Claims Act lawsuits may expose manufacturers to follow-on claims by private payors based on fraudulent marketing practices. This growth inlitigation has increased the risk that a biopharmaceutical company will have to defend a false claim action, pay settlement fines or restitution, as well as criminal and civil penalties, agree to comply with burdensome reporting and complianceobligations, and be excluded from Medicare, Medicaid, or other federal and state healthcare programs. If we do not lawfully promote our approved products, if any, we may become subject to such litigation and, if we do not successfully defend againstsuch actions, those actions may have a material adverse effect on our business, financial condition, results of operations, stock price and prospects.

Table of Contents

In the United States, the promotion of biopharmaceutical products aresubject to additional FDA requirements and restrictions on promotional statements. If after one or more of our current or future product candidates obtains marketing approval the FDA determines that our promotional activities violate its regulationsand policies pertaining to product promotion, it could request that we modify our promotional materials or subject us to regulatory or other enforcement actions, including issuance of warning letters or untitled letters, suspension or withdrawal ofan approved product from the market, requests for recalls, payment of civil fines, disgorgement of money, imposition of operating restrictions, injunctions or criminal prosecution, and other enforcement actions. Similarly, industry codes in foreignjurisdictions may prohibit companies from engaging in certain promotional activities and regulatory agencies in various countries may enforce violations of such codes with civil penalties. If we become subject to regulatory and enforcement actionsour business, financial condition, results of operations, stock price and prospects will be materially harmed.

Furthermore, the use of our products for indications other than those approved by the FDA or comparable foreign regulatoryauthorities may not effectively treat such conditions. Any such off-label use of our product candidates could harm our reputation in the marketplace among physicians and patients. There may also be increasedrisk of injury to patients if physicians attempt to use our products for these uses for which they are not approved, which could lead to product liability suits that that might require significant financial and management resources and that couldharm our reputation.

Even if we obtain FDA or European Commission (based on recommendation of the EMA) approval anyof our product candidates in the United States or EU, we may never obtain approval for or commercialize any of them in any other jurisdiction, which would limit our ability to realize their full market potential

In order to market any products in any particular jurisdiction, we must establish and comply with numerous and varyingregulatory requirements on a country-by-country basis regarding safety and efficacy.

Approval by the FDA in the United States or the European Commission (based on recommendation of the EMA) in the EU does notensure approval by regulatory authorities in other countries or jurisdictions. However, the failure to obtain approval in one jurisdiction may negatively impact our ability to obtain approval elsewhere. In addition, clinical trials conducted in onecountry may not be accepted by regulatory authorities in other countries, and regulatory approval in one country does not guarantee regulatory approval in any other country.

Approval processes vary among countries and can involve additional product testing and validation and additionaladministrative review periods. Seeking foreign regulatory approval could result in difficulties and increased costs for us and require additional preclinical studies or clinical trials which could be costly and time consuming. Regulatoryrequirements can vary widely from country to country and could delay or prevent the introduction of our products in those countries. We do not have any product candidates approved for sale in any jurisdiction, including in international markets, andwe do not have experience in obtaining regulatory approval in international markets. If we fail to comply with regulatory requirements in international markets or to obtain and maintain required approvals, or if regulatory approvals in internationalmarkets are delayed, our target market will be reduced and our ability to realize the full market potential of any product we develop will be unrealized.

Risks Related to Reliance on Third Parties

Some of our product candidates may be studied in clinical trials sponsored by organizations or agencies other than us,or in investigator-initiated clinical trials, which means we will have minimal or no control over the conduct of such trials.

We have and may continue to supply and otherwise support third party research, including investigator-initiated clinicaltrials. Investigator-initiated clinical trials pose similar risks as those set forth elsewhere in this “Risk Factor” section relating to our internally-sponsored clinical trials, but because we are not be the sponsors of these trials, wehave less control over the protocols, administration or conduct of these trials, including follow-up with patients and ongoing collection of data after treatment. The conduct or findings of these trials may have a negative impact on our developmentprograms notwithstanding that we have little involvement or control over these trials. As a result, we are subject to additional risks associated with the way investigator-initiated trials are conducted. In particular, we may be named in lawsuitsthat would lead to increased costs associated with legal defense. Additional risks include difficulties

Table of Contents

or delays in communicating with investigators or administrators, procedural delays and other timing issues and difficulties or differences in interpreting data. Third-party investigators maydesign clinical trials with clinical endpoints that are more difficult to achieve, or in other ways that increase the risk of negative clinical trial results compared to clinical trials that we may design on our own. Negative results ininvestigator-initiated clinical trials could have a material adverse effect on our efforts to obtain regulatory approval for our product candidates and the public perception of our product candidates. As a result, our lack of control over theconduct and timing of and communications with the FDA and other regulatory authorities regarding investigator-sponsored trials may expose us to additional risks and uncertainties, many of which are outside our control, and the occurrence of whichcould adversely affect the commercial prospects for our product candidates.

We rely on third parties to conduct,supervise, and monitor our clinical trials and perform some of our research and preclinical studies. If these third parties do not satisfactorily carry out their contractual duties or fail to meet expected deadlines, our development programs may bedelayed or subject to increased costs, each of which may have an adverse effect on our business and prospects.

Wedo not have the ability to conduct all aspects of our preclinical testing or clinical trials ourselves. As a result, we are and expect to remain dependent on third parties to conduct our current and future preclinical studies and clinical trials.CROs that manage our preclinical studies and clinical trials as well as clinical investigators, including in investigator-initiated clinical trials, and consultants play a significant role in the conduct of our preclinical studies and clinicaltrials and the subsequent collection and analysis of data. The timing of the initiation and completion of these studies and trials will therefore be partially controlled by such third parties and may result in delays to our development programs.Nevertheless, we are responsible for ensuring that each of our preclinical studies and clinical trials is conducted in accordance with the applicable protocol, legal requirements, and scientific standards, and our reliance on the CROs and otherthird parties does not relieve us of our regulatory responsibilities. We and our CROs are required to comply with Good Laboratory Practice (GLP) and GCP requirements, which are regulations and guidelines enforced by the FDA, the EMA, and comparableforeign regulatory authorities for all of our product candidates in clinical development. Regulatory authorities enforce these GLP and GCP requirements through periodic inspections of preclinical study sites, trial sponsors, clinical trialinvestigators and clinical trial sites. If we or any of our CROs or clinical trial sites, including clinical trial sites in investigator-initiated clinical trials, fail to comply with applicable GLP or GCP requirements, the data generated in ourpreclinical studies and clinical trials may be deemed unreliable, and the FDA, EMA, or comparable foreign regulatory authorities may require us to perform additional preclinical or clinical trials before approving our marketing applications. Inaddition, our clinical trials must be conducted with product produced under cGMP regulations. Our failure to comply with these regulations may require us to stop and/or repeat clinical trials, which would delay the marketing approval process.

There is no guarantee that any such CROs, clinical trial investigators or other third parties on which we rely will devoteadequate time and resources to our development activities or perform as contractually required. These risks are heightened as a result of the efforts of government agencies and the CROs themselves to limit the spread of COVID-19, including quarantines and shelter-in-place orders. If any of these third parties fail to meet expected deadlines, adhere toour clinical protocols or meet regulatory requirements, otherwise performs in a substandard manner, or terminates its engagement with us, the timelines for our development programs may be extended or delayed or our development activities may besuspended or terminated. If any of our clinical trial sites terminates for any reason, we may experience the loss of follow-up information on subjects enrolled in such clinical trials unless we are able totransfer those subjects to another qualified clinical trial site, which may be difficult or impossible. In addition, clinical trial investigators for our clinical trials or investigator-initiated clinical trials may serve as scientific advisors orconsultants to us from time to time and may receive cash or equity compensation in connection with such services. If these relationships and any related compensation result in perceived or actual conflicts of interest, or the FDA or any comparableforeign regulatory authority concludes that the financial relationship may have affected the interpretation of the trial, the integrity of the data generated at the applicable clinical trial site may be questioned and the utility of the clinicaltrial itself may be jeopardized, which could result in the delay or rejection of any marketing application we submit by the FDA or any comparable foreign regulatory authority. Any such delay or rejection could prevent us from commercializing ourproduct candidates.

Furthermore, these third parties may also have relationships with other entities, some of which maybe our competitors. If these third parties do not successfully carry out their contractual duties, meet expected deadlines

or conduct our clinical trials in accordance with regulatory requirements or our stated protocols, we will not be able to obtain, or may be delayed in obtaining, marketing approvals for ourproduct candidates and will not be able to, or may be delayed in our efforts to, successfully commercialize our products.

We rely on third parties to manufacture our product candidates, and we expect to continue to rely on third parties forthe clinical as well as any future commercial supply of our product candidates and other future product candidates. The development of our current and future product candidates, and the commercialization of any approved products, could be stopped,delayed or made less profitable if any such third party fails to provide us with sufficient clinical or commercial quantities of such product candidates or products, fails to do so at acceptable quality levels or prices or fails to achieve ormaintain satisfactory regulatory compliance.

We do not currently have, and we do not plan to build, theinfrastructure or capability internally to manufacture current product candidates or any future product candidates for use in the conduct of our clinical trials or, if approved, for commercial supply. We rely on, and expect to continue to rely on,contract manufacturing organizations (CMOs). Reliance on third-party providers may expose us to more risk than if we were to manufacture our product candidates ourselves. We do not control the manufacturing processes of the CMOs we contract with andare dependent on those third parties for the production of our product candidates in accordance with relevant applicable regulations such as cGMP, which includes, among other things, quality control, quality assurance and the maintenance of recordsand documentation.

In complying with the manufacturing regulations of the FDA and other comparable foreign regulatoryauthorities, we and our third-party suppliers must spend significant time, money and effort in the areas of design and development, testing, production, record-keeping and quality control to assure that the products meet applicable specificationsand other regulatory requirements. The failure to comply with these requirements could result in an enforcement action against us, including the seizure of products and shutting down of production. We and any of these third-party suppliers may alsobe subject to inspections by the FDA, EU Member States, coordinated by the EMA, or comparable foreign regulatory authorities. If any of our third-party suppliers fails to comply with cGMP or other applicable manufacturing regulations, our ability todevelop and commercialize our product candidates could suffer significant interruptions.

Our failure, or the failure ofour third-party manufacturers, to comply with applicable regulations could result in sanctions being imposed on us, including clinical holds, fines, injunctions, civil penalties, delays, suspension or withdrawal of approvals, license revocation,seizures or recalls of product candidates or drugs, operating restrictions and criminal prosecutions, any of which could significantly and adversely affect supplies of our products.

Any disruption, such as a fire, natural hazards or vandalism at our CMOs, or any impacts on our CMOs due to the COVID-19 pandemic, could significantly interrupt our manufacturing capability. We currently do not have alternative production plans in place or disaster-recovery facilities available. In case of a disruption, wewill have to establish alternative manufacturing sources. This would require substantial capital on our part, which we may not be able to obtain on commercially acceptable terms or at all. Additionally, we would likely experience months ofmanufacturing delays as we build facilities or locate alternative suppliers and seek and obtain necessary regulatory approvals. If this occurs, we will be unable to satisfy manufacturing needs on a timely basis, if at all. If changes to CMOs occur,then there also may be changes to manufacturing processes inherent in the setup of new operations for our product candidates and any products that may obtain approval in the future. Any such changes could require the conduct of bridging studiesbefore we can use any materials produced at new facilities or under new processes in clinical trials or, for any products reaching approval, in our commercial supply. Further, business interruption insurance may not adequately compensate us for anylosses that may occur and we would have to bear the additional cost of any disruption. For these reasons, a significant disruptive event of any CMOs could have drastic consequences, including placing our financial stability at risk.

Our product candidates and any drugs that we may develop may compete with other product candidates and drugs for access tomanufacturing facilities. There are no assurances we would be able to enter into similar commercial arrangements with other manufacturers that operate under cGMP regulations and that might be capable of manufacturing for us. Any performance failureon the part of our existing or future manufacturers could delay clinical development or marketing approval.

If we were to experience an unexpected loss of supply of or if any supplierwere unable to meet our clinical or commercial demand for any of our product candidates, we could experience delays in our planned clinical studies or commercialization. For example, the COVID-19 pandemic mayimpact our ability to procure sufficient supplies for the development of our current and future product candidates, and the extent of such impacts will depend on the severity and duration of the spread of the virus and the actions undertaken tocontain COVID-19 or treat its effects. We could be unable to find alternative suppliers of acceptable quality and experience that can produce and supply appropriate volumes at an acceptable cost or onfavorable terms. Moreover, our suppliers are often subject to strict manufacturing requirements and rigorous testing requirements, which could limit or delay production. The long transition periods necessary to switch manufacturers and suppliers, ifnecessary, would significantly delay our clinical trials and, for any product candidates that reach approval, the commercialization of our products, which would materially adversely affect our business, financial condition and results of operation.

We depend on third-party suppliers for materials that are necessary for the conduct of preclinical studies andmanufacture of our product candidates for clinical trials, and the loss of these third-party suppliers or their inability to supply us with sufficient quantities of adequate materials, or to do so at acceptable quality levels and on a timely basis,could harm our business.

Manufacturing our product candidates requires many reagents, which are substances used inour manufacturing processes to bring about chemical or biological reactions, and other specialty materials and equipment, some of which are manufactured or supplied by small companies with limited resources and experience to support commercialbiologics production. Further, our product candidates are typically administered with an adjuvant, such as Montanide. We currently depend on a limited number of vendors for certain materials and equipment used in the manufacture of our productcandidates. For example, we currently use facilities and equipment at external CMOs, as well as supply sources internal to the collaboration for vector supply. Our use of CMOs increases the risk of delays in production or insufficient supplies as wetransfer our manufacturing technology to these CMOs and as they gain experience with our supply requirements. Some of these suppliers may not have the capacity to support clinical trials and commercial products manufactured under cGMP bybiopharmaceutical firms or may otherwise be ill-equipped to support our needs. We also do not have supply contracts with many of these suppliers and may not be able to obtain supply contracts with them onacceptable terms or at all. Accordingly, we may experience delays in receiving key materials and equipment to support clinical or commercial manufacturing.

For some of these reagents, equipment, and materials, we rely and may in the future rely on sole source vendors or a limitednumber of vendors. The supply of the reagents and other specialty materials and equipment that are necessary to produce our product candidates could be reduced or interrupted at any time. In such case, identifying and engaging an alternativesupplier or manufacturer could result in delay, and we may not be able to find other acceptable suppliers or manufacturers on acceptable terms, or at all. Switching suppliers or manufacturers may involve substantial costs and is likely to result ina delay in our desired clinical and commercial timelines. If we change suppliers or manufacturers for commercial production, applicable regulatory agencies may require us to conduct additional studies or trials. If key suppliers or manufacturers arelost, or if the supply of the materials is diminished or discontinued, we may not be able to develop, manufacture and market our product candidates in a timely and competitive manner, or at all. An inability to continue to source product from any ofthese suppliers, which could be due to a number of issues, including regulatory actions or requirements affecting the supplier, adverse financial or other strategic developments experienced by a supplier, labor disputes or shortages, unexpecteddemands or quality issues, could adversely affect our ability to satisfy demand for our product candidates, which could adversely and materially affect our product sales and operating results or our ability to conduct clinical trials, either ofwhich could significantly harm our business.

As we continue to develop and scale our manufacturing process, we expectthat we will need to obtain rights to and supplies of certain materials and equipment to be used as part of that process. We may not be able to obtain rights to such materials on commercially reasonable terms, or at all, and if we are unable toalter our process in a commercially viable manner to avoid the use of such materials or find a suitable substitute, it would have a material adverse effect on our business. Even if we are able to alter our process so as to use other materials orequipment, such a change may lead to a delay in our clinical development and/or commercialization plans. If such a change occurs for product candidate that is already in clinical testing, the change may require us

to perform both ex vivo comparability studies and to collect additional data from patients prior to undertaking more advanced clinical trials. These factors could cause the delay of studies ortrials, regulatory submissions, required approvals or commercialization of product candidates that we develop, cause us to incur higher costs and prevent us from commercializing our product candidates successfully.

Our reliance on third parties requires us to share our trade secrets, which increases the possibility that a competitorwill discover them or that our trade secrets will be misappropriated or disclosed.

Because we rely on thirdparties to research and develop and to manufacture our product candidates, we must share trade secrets with them. We seek to protect our proprietary technology in part by entering into confidentiality agreements and, if applicable, material transferagreements, consulting agreements or other similar agreements with our advisors, employees, third-party contractors and consultants prior to beginning research or disclosing proprietary information. These agreements typically limit the rights of thethird parties to use or disclose our confidential information, including our trade secrets. Despite the contractual provisions employed when working with third parties, the need to share trade secrets and other confidential information increases therisk that such trade secrets become known by our competitors, are inadvertently incorporated into the technology of others, or are disclosed or used in violation of these agreements. Given that our proprietary position is based, in part, on our know-how and trade secrets, a competitor’s independent discovery of our trade secrets or other unauthorized use or disclosure would impair our competitive position and may have a material adverse effect on ourbusiness.

In addition, these agreements typically restrict the ability of our advisors, employees, third-partycontractors and consultants to publish data potentially relating to our trade secrets, although our agreements may contain certain limited publication rights. For example, any academic institution that we may collaborate with will likely expect tobe granted rights to publish data arising out of such collaboration and any joint research and development programs may require us to share trade secrets under the terms of our research and development or similar agreements. Despite our efforts toprotect our trade secrets, our competitors may discover our trade secrets, either through breach of our agreements with third parties, independent development or publication of information by any of our third-party collaborators. A competitor’sdiscovery of our trade secrets would impair our competitive position and have an adverse impact on our business.

Wemay form or seek partnerships, collaborations or strategic alliances or enter into additional licensing arrangements in the future, and we may not realize the benefits of such partnerships, collaborations, alliances or licensing arrangements.

We may form or seek partnerships or strategic alliances, create joint ventures or collaborations, or enter intolicensing arrangements with third parties that we believe will complement or augment our development and commercialization efforts with respect to our product candidates and any future product candidates that we may develop. For example, we haveentered into a collaborative agreement with Merck pursuant to which they provide the pembrolizumab used in our “open-label”, randomized Phase 1/2 trial of IO102 in combination with pembrolizumab with or without chemotherapy as first-linetreatment for patients with metastatic NSCLC. Any of these relationships may require us to incur non-recurring and other charges, increase our near and long-term expenditures, require us to share the data withsuch collaborators or restrict our ability to utilize certain data arising out of these collaboration arrangements, issue securities that dilute our existing stockholders or disrupt our management and business.

In addition, we face significant competition in seeking appropriate strategic partners and the negotiation process istime-consuming and complex. Moreover, we may not be successful in our efforts to establish a strategic partnership or other alternative arrangements for our product candidates because they may be deemed to be at too early of a stage of developmentfor collaborative effort and third parties may not view our product candidates as having the requisite potential to demonstrate safety and efficacy and obtain marketing approval.

Further, collaborations involving our product candidates are subject to numerous risks, which may include the following:

 

  

collaborators have significant discretion in determining the efforts and resources that they will apply to acollaboration;

 

37


Table of Contents
  

collaborators may not pursue development and commercialization of our product candidates or may elect not tocontinue or renew development or commercialization of our product candidates based on clinical trial results, changes in their strategic focus due to the acquisition of competitive products, availability of funding or other external factors, such asa business combination that diverts resources or creates competing priorities;

 

  

collaborators may delay clinical trials, provide insufficient funding for a clinical trial, stop a clinicaltrial, abandon a product candidate, repeat or conduct new clinical trials or require a new formulation of a product candidate for clinical testing;

 

  

collaborators could independently develop, or develop with third parties, products that compete directly orindirectly with our product candidates;

 

  

a collaborator with marketing and distribution rights to one or more products may not commit sufficientresources to their marketing and distribution;

 

  

collaborators may not properly maintain or defend our intellectual property rights or may use our intellectualproperty or proprietary information in a way that gives rise to actual or threatened litigation that could jeopardize or invalidate our intellectual property or proprietary information or expose us to potential liability;

 

  

disputes, including contract disputes, may arise between us and a collaborator that cause the delay ortermination of the research, development or commercialization of our product candidates, or that result in costly litigation or arbitration that diverts management attention and resources;

 

  

collaborations may be terminated and, if terminated, may result in a need for additional capital to pursuefurther development or commercialization of the applicable product candidates; and

 

  

collaborators may own or co-own intellectual property covering ourproducts that results from our collaborating with them, and in such cases, we would not have the exclusive right to commercialize such intellectual property.

As a result, if we enter into additional collaboration agreements and strategic partnerships or license our productcandidates, we may not be able to realize the benefit of such transactions if we are unable to successfully integrate them with our existing operations and company culture, which could delay our timelines or otherwise adversely affect our business.We also cannot be certain that, following a strategic transaction or license, we will achieve the revenue or specific net income that justifies such transaction. Any delays in entering into new collaborations or strategic partnership agreementsrelated to our product candidates could delay the development and commercialization of our product candidates in certain geographies for certain indications, which would harm our business prospects, financial condition and results of operations.

Risks Related to Our Industry and Business Operations

The outbreak of COVID-19, or similar public health crises, could have a materialadverse impact on our business, financial condition and results of operations, including the execution of our planned clinical trials.

In December 2019, a novel strain of coronavirus,SARS-CoV-2, was identified. This virus has since spread globally, including within the United States and while cases and hospitalization are currently on the decline inthe United States, there can be no assurances they will not continue at the current rate or increase in the future especially in light of the number of variants that are emerging across the world. Governments in the United States and elsewhere havetaken and are continuing to take severe measures to slow the spread of COVID-19, including requiring that certain businesses close or conduct only the minimum necessary operations. The pandemic and governmentmeasures taken in response have also had a significant impact, both direct and indirect, on businesses and commerce, as worker shortages have occurred, supply chains have been disrupted, facilities and production have been suspended, and demand forcertain goods and services, such as medical services and supplies, has spiked, while demand for other goods and services, such as travel, has fallen. The extent to which COVID-19 will continue to impact ourbusiness and operating results will depend on future developments that are highly uncertain and cannot be accurately predicted, including new information that may emerge concerning COVID-19 and governmentmeasures taken in response.

Site initiation, participant recruitment and enrollment, participant dosing,distribution of clinical trial materials, study monitoring and data analysis for our planned clinical trials may be delayed due to changes in hospital or university policies, federal, state or local regulations, prioritization of hospital resourcestoward pandemic efforts, or other reasons related to the pandemic. Additionally, some participants and clinical investigators may not be able to comply with clinical trial protocols. For example, quarantines or other travel limitations (whethervoluntary or required) may impede participant movement, affect sponsor access to study sites, or interrupt healthcare services, and we may be unable to conduct its planned clinical trials. If the global effort to control the spread of COVID-19 and treat COVID-19 patients continues for an extended period of time, we risk a delay in activating sites and enrolling subjects as previously projected. Any suchdelays to our planned clinical trials for IO102-IO103 and any future clinical trials could impact the use and sufficiency of our existing cash reserves, and we may be required to raise additional capital earlier than it had previously planned. Wemay be unable to raise additional capital if and when needed, which may result in further delays or suspension of our development plans.

Further, infections and deaths related to COVID-19 are disrupting certain healthcareand healthcare regulatory systems globally. Such disruptions could divert healthcare resources away from, or materially delay review by, the FDA and comparable foreign regulatory agencies. It is unknown how long these disruptions could continue,were they to occur. Any elongation or de-prioritization of our clinical trials or delay in regulatory review resulting from such disruptions could materially adversely affect the development and study of itsproduct candidates.

We currently utilize third parties to, among other things, manufacture raw materials and our productcandidates, components, parts, and consumables, and to perform quality testing. If either we or any third-party in the supply chain for materials used in the production of its product candidates are adversely impacted by restrictions resulting fromthe COVID-19 pandemic, our supply chain may be disrupted, limiting our ability to manufacture product candidates for its clinical trials.

In response to the COVID-19 pandemic, we complied with applicable regulation andlimited required on-site staff to essential workers, with the balance of its employees continuing their work primarily outside of our offices. Due to shelter-in-place orders or other mandated local travel restrictions, third parties conducting clinical or manufacturing activities may not be able to access laboratory or manufacturing space, and our coreactivities may be significantly limited or curtailed, possibly for an extended period of time.

While the potentialeconomic impact brought by and the duration of the pandemic may be difficult to assess or predict, it has already caused, and is likely to result in further, significant disruption of global financial markets and the trading prices ofbiopharmaceutical companies have been highly volatile as a result of the COVID-19 pandemic, which may reduce our ability to access capital either at all or on favorable terms. In addition, a recession,depression or other sustained adverse market event resulting from the global effort to control COVID-19 infections could materially and adversely affect our business.

The ultimate impact of the current pandemic, or any other health epidemic, is highly uncertain and subject to change. We donot yet know the full extent of potential delays or impacts on our business, our planned clinical trials, healthcare systems or the global economy as a whole. However, these effects could have a material adverse impact on our business, financialcondition and results of operations.

Disruptions at the FDA, EMA, SEC and other government agencies and regulatoryauthorities caused by funding shortages or global health concerns could hinder their ability to hire and retain key leadership and other personnel, prevent new products and services from being developed or commercialized in a timely manner orotherwise prevent those agencies from performing normal governmental functions on which the operation of our business may rely, which could negatively impact our business.

The ability of the FDA, EMA, and other comparable foreign regulatory authorities to review and approve new products can beaffected by a variety of factors, including government budget and funding levels, the ability to hire and retain key personnel and accept the payment of user fees, and statutory, regulatory, and policy

changes. Average review times at regulatory authorities and government agencies have fluctuated in recent years as a result. In addition, government funding of the SEC and other governmentagencies on which our operations may rely, including those that fund research and development activities is subject to the political process, which is inherently fluid and unpredictable.

Disruptions at the FDA and other agencies such as the EMA following its post-Brexit relocation and resulting staff changes aswell as necessary COVID-19 prioritizations may also slow the time necessary for new products to be reviewed and/or approved by necessary government agencies, which would adversely affect our business. Forexample, in recent years, including in 2018 and 2019, the U.S. government shut down several times and certain regulatory agencies, such as the FDA and the SEC, had to furlough critical employees and stop critical activities. If a prolongedgovernment shutdown occurs, it could significantly impact the ability of the FDA to review and process our regulatory submissions, which could have a material adverse effect on our business. Further, upon completion of this offering and in ouroperations as a public company, future government shutdowns could impact our ability to access the public markets and obtain necessary capital in order to properly capitalize and continue our operations.

Separately, in response to the COVID-19 pandemic, on March 10, 2020 the FDAannounced its intention to postpone most inspections of foreign manufacturing facilities, and on March 18, 2020, the FDA temporarily postponed routine surveillance inspections of domestic manufacturing facilities. On July 10, 2020, the FDAannounced its intention to resume certain on-site inspections of domestic manufacturing facilities subject to a risk-based prioritization system. The FDA intends to use this risk-based assessment system toidentify the categories of regulatory activity that can occur within a given geographic area, ranging from mission critical inspections to resumption of all regulatory activities. Additionally, on April 15, 2021, the FDA issued a guidancedocument in which the FDA described its plans to conduct voluntary remote interactive evaluations of certain drug manufacturing facilities and clinical research sites. According to the guidance, the FDA intends to request such remote interactiveevaluations in situations where an in-person inspection would not be prioritized, deemed mission-critical, or where direct inspection is otherwise limited by travel restrictions, but where the FDA determinesthat remote evaluation would still be appropriate. Regulatory authorities outside the United States may adopt similar restrictions or other policy measures in response to the COVID-19 pandemic. If a prolongedgovernment shutdown occurs, or if global health concerns continue to prevent the FDA or other regulatory authorities from conducting their regular inspections, reviews, or other regulatory activities, it could significantly impact the ability of theFDA or other regulatory authorities to timely review and process our regulatory submissions, which could have a material adverse effect on our business.

The United Kingdom’s withdrawal from the EU may cause additional administrative burdens and strain on regulatoryauthorities in the EU, this may delay our ability to obtain regulatory approvals of our product candidates in the EU and may require us to incur additional expenses in order to develop, manufacture and commercialize our product candidates in the EU.

The United Kingdom formally exited the EU, commonly referred to as Brexit, on January 31, 2020. Under theterms of its departure, the United Kingdom entered a transition period (the Transition Period), during which it continued to follow all EU rules. The Transition Period ended on December 31, 2020. On December 30, 2020, the United Kingdomand EU signed the Trade and Cooperation Agreement (TCA), which includes an agreement on free trade between the two parties. The TCA does not contain wholesale mutual recognition of regulatory regimes for pharmaceuticals as was hoped. There is mutualrecognition of cGMP inspections of manufacturing facilities but it does not include reciprocal arrangements for the recognition of batch testing certification, in order to avoid unnecessary re-testing onimportation of products.

There is considerable uncertainty resulting from a lack of precedent and the complexity of theUnited Kingdom and the EU’s intertwined legal regimes as to how Brexit will impact the life sciences industry in Europe, including our company, including with respect to ongoing or future clinical trials. The impact will largely depend on themodel and means by which the United Kingdom’s relationship with the EU is governed

post-Brexit and the extent to which the United Kingdom chooses to diverge from the EU regulatory framework. For example, Great Britain is no longer covered by the centralized procedures forobtaining EU-wide marketing authorizations and our products therefore require a separate marketing authorization to allow us to market such products in Great Britain. It is unclear as to whether the relevantauthorities in the EU and the United Kingdom are adequately prepared for the additional administrative burden caused by Brexit. Any delay in obtaining, or an inability to obtain, any marketing approvals, as a result of Brexit or otherwise, wouldprevent us from or delay us commercializing our product candidates in the United Kingdom and/or the European Economic Area (EEA) and restrict our ability to generate revenue and achieve and sustain profitability. In the short term, there is a riskof disrupted import and export processes due to a lack of administrative processing capacity by the respective United Kingdom and EU customs agencies that may delay time-sensitive shipments and may negatively impact our product supply chain.

We may be exposed to significant foreign exchange risk.

We have operations in Denmark and we incur portions of our expenses, and may in the future derive revenues, in a variety ofcurrencies. As a result, we are exposed to foreign currency exchange risk as our results of operations and cash flows are subject to fluctuations in foreign currency exchange rates. Fluctuations in currency exchange rates have had, and will continueto have, an impact on our results as expressed in U.S. dollars. We currently do not engage in hedging transactions to protect against uncertainty in future exchange rates between particular foreign currencies and the U.S. dollar. We cannot predictthe impact of foreign currency fluctuations, and foreign currency fluctuations in the future may adversely affect our financial condition, results of operations and cash flows.

Our employees, principal investigators, consultants and commercial partners may engage in misconduct or other improperactivities, including non-compliance with regulatory standards and requirements and insider trading.

We are exposed to the risk of fraud or other misconduct by our employees, principal investigators, consultants and commercialpartners. Misconduct by these parties could include intentional failures to comply with the regulations of the FDA and other comparable foreign regulatory authorities, provide accurate information to the FDA and other comparable foreign regulatoryauthorities, comply with healthcare fraud and abuse laws and regulations in the United States, EU, UK, and in other jurisdictions, report financial information or data accurately or disclose unauthorized activities to us. In particular, sales,marketing and business arrangements in the healthcare industry are subject to extensive laws and regulations intended to prevent fraud, misconduct, kickbacks, self-dealing and other abusive practices. These laws and regulations may restrict orprohibit a wide range of pricing, discounting, marketing and promotion, sales commission, customer incentive programs and other business arrangements. Such misconduct could also involve the improper use of information obtained in the course ofclinical trials, which could result in regulatory sanctions and cause serious harm to our reputation. It is not always possible to identify and deter employee misconduct, and the precautions we take to detect and prevent this activity may not beeffective in controlling unknown or unmanaged risks or losses or in protecting us from governmental investigations or other actions or lawsuits stemming from a failure to comply with these laws or regulations. If any such actions are institutedagainst us those actions could have a significant impact on our business, including the imposition of significant civil, criminal and administrative penalties, damages, fines, disgorgement, imprisonment, exclusion from government funded healthcareprograms, such as Medicare and Medicaid, contractual damages, reputational harm, diminished profits and future earnings, additional reporting obligations and oversight if subject to a corporate integrity agreement or other agreement to resolveallegations of non-compliance with these laws, and the curtailment or restructuring of our operations.

We face potential product liability, and, if successful claims arebrought against us, we may incur substantial liability and costs. if the use of our product candidates harms patients or is perceived to harm patients even when such harm is unrelated to our product candidates, our regulatory approvals could berevoked or otherwise negatively impacted and we could be subject to costly and damaging product liability claims.

The use of our product candidates in clinical trials and the sale of any products for which we obtain marketing approvalexposes us to the risk of product liability claims. Product liability claims might be brought against us by consumers, healthcare providers, pharmaceutical companies or others selling or otherwise coming into contact with our products. There is arisk that our product candidates may induce adverse events. If we cannot successfully defend against product liability claims, we could incur substantial liability and costs. In addition, regardless of merit or eventual outcome, product liabilityclaims may result in:

 

  

impairment of our business reputation;

 

  

withdrawal of clinical trial participants;

 

  

costs due to related litigation;

 

  

distraction of management’s attention from our primary business;

 

  

substantial monetary awards to patients or other claimants;

 

  

the inability to commercialize our product candidates; and

 

  

decreased demand for our product candidates, if approved for commercial sale.

We believe our product liability insurance coverage is sufficient in light of our current clinical programs; however, we maynot be able to maintain insurance coverage at a reasonable cost or in sufficient amounts to protect us against losses due to liability. If and when we obtain marketing approval for product candidates, we intend to expand our insurance coverage toinclude the sale of commercial products; however, we may be unable to obtain product liability insurance on commercially reasonable terms or in adequate amounts. On occasion, large judgments have been awarded in class action lawsuits based on drugsor medical treatments that had unanticipated adverse effects. A successful product liability claims, or series of claims brought against us could cause our stock price to decline and, if judgments exceed our insurance coverage, could adverselyaffect our results of operations and business.

Patients with cancer and other diseases targeted by our product candidatesare often already in severe and advanced stages of disease and have both known and unknown significant pre-existing and potentially life-threatening health risks. During the course of treatment, patients maysuffer adverse events, including death, for reasons that may be related to our product candidates. Such events could subject us to costly litigation, require us to pay substantial amounts of money to injured patients, delay, negatively impact or endour opportunity to receive or maintain regulatory approval to market our products, or require us to suspend or abandon our commercialization efforts. Even in a circumstance in which we do not believe that an adverse event is related to our products,the investigation into the circumstance may be time-consuming or inconclusive. These investigations may divide the attention of our management team, interrupt our sales efforts, delay our regulatory approval process in other countries, or impact andlimit the type of regulatory approvals our product candidates receive or maintain. As a result of these factors, a product liability claim, even if successfully defended, could have a material adverse effect on our business, financial condition orresults of operations.

Our future success depends on our ability to retain key members of senior management and toattract, retain and motivate qualified personnel.

Our ability to compete in the highly competitivebiopharmaceutical industry depends upon our ability to attract and retain highly qualified management, research and development, clinical, financial and business development personnel. We are highly dependent on our management, scientific andmedical personnel,

Table of Contents

including Mai Britt Zocca, Ph.D., our Chief Executive Officer, Keith Vendola, M.D., M.B.A., our Chief Financial Officer, Eva Ehrnrooth, M.D., Ph.D., our Chief Medical Officer, and Muhammad Al-Hajj, Ph.D., our Chief Scientific Officer. Our senior management may terminate their employment with us at any time and will continue to be able to do so after the closing of this offering. We do not maintain“key person” insurance for any of our employees.

Recruiting and retaining qualified scientific and clinicalpersonnel and, if we progress the development of any of our product candidates, commercialization, manufacturing and sales and marketing personnel, will be critical to our success. The loss of the services of members of our senior management orother key employees could impede the achievement of our research, development and commercialization objectives and seriously harm our ability to successfully implement our business strategy. Furthermore, replacing members of our senior managementand key employees may be difficult and may take an extended period of time because of the limited number of individuals in our industry with the breadth of skills and experience required to successfully develop, gain regulatory approval of andcommercialize our product candidates. Our success also depends on our ability to continue to attract, retain and motivate highly skilled junior, mid-level and senior managers, as well as junior, mid-level and senior scientific and medical personnel. Competition to hire from this limited candidate pool is intense, and we may be unable to hire, train, retain or motivate these key personnel on acceptable termsgiven the competition among numerous pharmaceutical and biotechnology companies for similar personnel. We also experience competition for the hiring of scientific and clinical personnel from universities and research institutions. In addition, werely on consultants and advisors, including scientific and clinical advisors, to assist us in formulating our research and development and commercialization strategy. Our consultants and advisors may have commitments under consulting or advisorycontracts with other entities that may limit their availability to us. If we are unable to continue to attract and retain high-quality personnel, our ability to pursue our growth strategy will be limited.

We expect to expand our clinical development and regulatory capabilities and potentially implement sales, marketing anddistribution capabilities, and as a result, we may encounter difficulties in managing our growth, which could disrupt our operations.

As of June 30, 2021 we had 19 full-time employees. As our development progresses, we expect to experience significant growth inthe number of our employees and the scope of our operations, particularly in the areas of clinical product development, regulatory affairs, manufacturing and, if any of our product candidates receives marketing approval, sales, marketing anddistribution. To manage our anticipated future growth, we must continue to implement and improve our managerial, operational and financial systems, expand our facilities and continue to recruit and train additional qualified personnel. Due to ourlimited financial resources and the limited experience of our management team in managing a company with such anticipated growth, we may not be able to effectively manage the expansion of our operations or recruit and train additional qualifiedpersonnel. The expansion of our operations may lead to significant costs and may divert our management and business development resources. Any inability to manage growth could delay the execution of our business plans or disrupt our operations.

We face substantial competition, which may result in others discovering, developing or commercializing products morequickly or marketing them more successfully than us.

The development and commercialization of new products ishighly competitive. We expect to compete in the segments of the pharmaceutical, biotechnology and other related markets that pursue immuno-oncology treatments. Our commercial opportunity could be reduced or eliminated if our competitors develop andcommercialize products that are safer, more effective, have fewer or less severe side effects, are more convenient, or are less expensive than any products that we may develop. Our competitors also may obtain regulatory approval from the FDA orother comparable foreign regulatory authorities for their products more rapidly than we may obtain approval for ours, if ever, which could result in our competitors establishing a strong market position before we are able to enter the market or makeour development more complicated. Moreover,

with the proliferation of new drugs and therapies into oncology, we expect to face increasingly intense competition as new technologies become available. If we fail to stay at the forefront oftechnological change, we may be unable to compete effectively. Any product candidates that we successfully develop and commercialize will compete with existing therapies and new therapies that may become available in the future. The highlycompetitive nature of and rapid technological changes in the biotechnology and pharmaceutical industries could render our product candidates or our technology obsolete, less competitive or uneconomical.

Other products in a similar class as some of our product candidates have already been approved and other products in the sameclass are further along in development. As more product candidates within a particular class of biopharmaceutical products proceed through clinical development to regulatory review and approval, the amount and type of clinical data that may berequired by regulatory authorities may increase or change. Consequently, the results of our clinical trials for product candidates in those class will likely need to show a risk benefit profile that is competitive with or more favorable than thoseproducts and product candidates in order to obtain marketing approval or, if approved, a product label that is favorable for commercialization. If the risk benefit profile is not competitive with those products or product candidates, we may havedeveloped a product that is not commercially viable, that we are not able to sell profitably or that is unable to achieve favorable pricing or reimbursement. In such circumstances, our future product revenue and financial condition would bematerially and adversely affected.

Specifically, there are many companies that have commercialized or are developingimmuno-oncology treatments for cancer including large pharmaceutical and biotechnology companies such as Amgen Inc. (Amgen), AstraZeneca plc (AstraZeneca) and its subsidiary, MedImmune, LLC (MedImmune), Bristol-Myers Squibb Company (BMS), Merck,Novartis AG (Novartis), Pfizer Inc. (Pfizer) and F. Hoffman-La Roche AG (Roche), and its subsidiary Genentech, Inc. (Genentech). In melanoma specifically, the dominant market players are nivolumab, marketed byBMS and Ono Pharmaceutical Co., Ltd. (Ono), nivolumab & ipilimumab, marketed by BMS and Ono, and pembrolizumab, marketed by Merck. We are also aware of several companies testing their compounds in combination with nivolumab orpembrolizumab. Select programs in late stage development include lymphocyte activation gene-3 (LAG-3) assets from BMS (relatlimab) and modified interleukin-2 (IL-2) assets from Nektar Therapeutics bempegaldesleukin). In earlier stage development there are also BioNTech SE (BioNTech) withNEO-PV-01 and Karyopharm Therapeutics, Inc. (Karyopharm) with selinexor.

Many of our competitors, either alone or with their collaboration partners, have significantly greater financial resources andexpertise in research and development, preclinical testing, clinical trials, manufacturing and marketing than we do. Future collaborations and mergers and acquisitions may result in further resource concentration among a smaller number ofcompetitors. Smaller or early-stage companies may also prove to be significant competitors, particularly through collaborative arrangements with large and established companies. These competitors will also compete with us in recruiting and retainingqualified scientific and management personnel and establishing clinical trial sites and subject registration for clinical trials, as well as in acquiring technologies complementary to, or that maybe necessary for, our programs.

The key competitive factors affecting the success of all of our programs are likely to be efficacy, safety, and convenience.If we are not successful in developing, commercializing and achieving higher levels of reimbursement than our competitors, we will not be able to compete against them and our business would be materially harmed.

The tax authorities in the jurisdictions in which we operate may challenge our transfer pricing procedures.

We are a multinational business that operates in Denmark and other tax jurisdictions, and the tax laws of those jurisdictionsgenerally require that royalty and other payments between affiliated companies in different jurisdictions be the same as those between unrelated companies dealing at arm’s length, and that such prices are supported by contemporaneousdocumentation. While we believe that we operate in compliance with applicable

transfer pricing laws and intend to continue to do so, our transfer pricing procedures are not binding on applicable tax authorities. If tax authorities in any of these jurisdictions were tosuccessfully challenge our transfer prices as not reflecting arm’s length transactions, they could require us to adjust our transfer prices and thereby reallocate our income or deductions to reflect these revised transfer prices, which couldresult in a higher overall tax liability to us and possibly interest and penalties.

Additionally, tax authorities in thejurisdictions in which we operate may challenge our treatment of the Corporate Reorganization. No assets (either physical or intangible) are being transferred from Denmark to the U.S. pursuant to the Corporate Reorganization, nor are any existingbusiness functions or units operating from Denmark being transferred from IO Biotech ApS to IO Biotech, Inc. as part of the Corporate Reorganization to form part of our U.S. operations. Accordingly, we do not intend to treat the CorporateReorganization as a deemed sale of all or part of our business by IO Biotech ApS to IO Biotech, Inc. If Danish tax authorities were to disagree with our position and treat the Corporate Reorganization or any of our activities thereafter as a deemedsale, in whole or in part, of intellectual property rights and/or other assets owned by IO Biotech ApS to IO Biotech, Inc., we could be subject to a Danish tax, the current rate of which is 22%, on the gain realized calculated as the differencebetween the fair market value and the tax value of the assets, at the time of the deemed sale of the assets from Denmark as determined by the Danish tax authorities.

Finally, the nature of our operations can produce conflicting claims from tax authorities in different countries as to theprofits to be taxed in the individual countries. The jurisdictions in which we operate have double tax treaties with other jurisdictions, which provide a framework for mitigating the impact of double taxation on our revenues and capital gains.However, mechanisms developed to resolve such conflicting claims are largely untested, can be expected to be very lengthy, and do not always contain a mandatory dispute resolution clause. In recent years, tax authorities around the world haveincreased their scrutiny of company tax filings, and have become more rigid in exercising any discretion they may have.

In general, tax reform efforts, including with respect to transfer pricing, will require us to continually assess ourorganizational structure and could lead to an increased risk of international tax disputes, an increase in our effective tax rate and an adverse effect on our financial condition.

We have net operating losses to be carried forward, which may become devalued if we do not generate sufficient futuretaxable income, applicable corporate tax rates are reduced or if we experience an ownership change.

Our totalgross deferred tax assets as of December 31, 2020 were $5.4 million. Of that amount, $5.4 million relates to gross deferred tax assets in IO Biotech ApS. Our anticipated activities are also expected to result in future significant net operatinglosses in Denmark resulting in additional deferred tax assets. Utilization of most deferred tax assets is dependent on generating sufficient future taxable income in the appropriate jurisdiction and/or entity. The company has provided a valuationallowance of $5.4 million on our net deferred tax assets as of December 31, 2020, based on all available evidence, it is considered more likely than not that all the recorded deferred tax assets will not be realized in a future period.Additionally, most of our deferred tax assets are determined by reference to applicable corporate income tax rates in Denmark. Accordingly, in the event of a reduction of any such corporate income tax rates, the carrying value of certain of ourdeferred tax assets would decrease.

Moreover, our ability to use our net operating losses and other deferred tax assetsto offset future taxable income in Denmark may be limited if we experience an ownership change. We may experience ownership changes in the future as a result of this offering or subsequent shifts in our stock ownership, some of which are outside theCompany’s control.

For Danish income tax purposes, an ownership change will generally occur when one, or severalshareholders together, at once or successively, acquire shares representing more than 50 percent of the share

capital or voting power. Although such an ownership change entails no reduction of the amount of net operating losses to be carried forward, the utilization is restricted to exclude offsettingagainst positive net capital income (e.g. income from interest, dividend and royalty) on net operating losses incurred in a previous income year, where the ownership differs by 50 percent (under section 12D of the Danish Corporate Tax Act). Therestriction may limit future offsetting against net operating profits, when the ownership change is due to the listing on an exchange.

For U.S. federal income tax purposes, an ownership change will generally occur when the percentage of our stock (by value)owned by one or more “5% shareholders” (as defined in the U.S. Internal Revenue Code of 1986, as amended) has increased by more than 50% over the lowest percentage owned by such shareholders at any time during the prior three years(calculated on a rolling basis). We anticipate that we will incur losses in the United States in the foreseeable future related to our research and development activities. Due to potential ownership changes under Section 382 of the Code, we maybe limited in our ability to realize a tax benefit from the use of such losses, whether or not we attain profitability in future years.

In addition, our ability to utilize any future net operating losses may be limited by Pub. L.115-97, enacted in 2017 and commonly known as the Tax Cuts and Jobs Act of 2017 (TCJA). Under the TCJA, the amount of our net operating losses that we are permitted to deduct in any taxable year is limited to80% of our taxable income in such year, where taxable income is determined without regard to the net operating loss deduction itself, while allowing unused net operating losses to be carried forward indefinitely.

For these reasons, a material devaluation in our deferred tax assets due to insufficient taxable income, lower corporateincome tax rates or ownership change would have an adverse effect on our results of operations and financial condition.

We may be subject to current taxation on some of the income of our foreign subsidiaries even absent any cashdistributions.

Because we hold directly or indirectly all of the shares of our foreign subsidiaries, including IOBiotech ApS, such subsidiaries are treated as controlled foreign corporations (CFC) for U.S. federal income tax purposes. For U.S. federal income tax purposes, IO Biotech, Inc. will therefore need to include in its taxable income each year its“global intangible low-taxed income” and IO Biotech ApS’s “subpart F income”, if any, even if no distributions are made.

Our foreign subsidiaries may directly become subject to U.S. federal income tax and be subject to a branch profits taxin the United States, which could reduce our after-tax returns and the value of our shares.

We currently intend to conduct substantially all of our businesses and operations in a manner such that our foreignsubsidiaries will not be treated as engaged in a trade or business in the United States and will not be subject to additional U.S. income tax or branch profits tax. However, it is not entirely clear when a foreign subsidiary is treated as beingengaged in a trade or business in the United States for U.S. federal income tax purposes. Accordingly, we cannot assure you that the Internal Revenue Service (IRS) will not contend, perhaps successfully, that our foreign subsidiaries were engaged ina trade or business in the United States or are subject to more U.S. income tax than they currently incur. A foreign corporation deemed to be so engaged would be subject to U.S. federal income tax on its income that is treated as effectivelyconnected with the conduct of that trade or business, as well as to branch profits tax on its “dividend equivalent amount,” unless the corporation is entitled to relief under an applicable tax treaty, which is determined on an annualbasis.

Our business operations and current and future relationships withinvestigators, health care professionals, consultants, third-party payors and customers are subject, directly or indirectly, to federal and state healthcare fraud and abuse laws, transparency laws and other healthcare laws and regulations. If we areunable to comply, or have not fully complied, with such laws, we could face substantial penalties.

Healthcareproviders and others play a primary role in the recommendation and prescription of any products for which we obtain marketing approval. Although we do not currently have any products on the market, our operations and current and future arrangementswith investigators, healthcare professionals, customers and third-party payors, may be subject to various U.S. federal and state healthcare laws and regulations, including, without limitation, the U.S. federal Anti-Kickback Statute, the U.S. federalcivil and criminal false claims laws and the Physician Payments Sunshine Act and regulations. These laws may impact, among other things, our current business operations, including our clinical research activities, and proposed sales, marketing andeducation programs and constrain the business of financial arrangements and relationships with healthcare providers and other parties through which we may market, sell and distribute our products for which we obtain marketing approval. In addition,we may be subject to additional healthcare, statutory and regulatory requirements and enforcement by foreign regulatory authorities in jurisdictions in which we conduct our business. The laws that may affect our ability to operate include:

 

  

the U.S. federal Anti-Kickback Statute, a criminal law which prohibits, among other things, persons orentities from knowingly and willfully soliciting, offering, receiving or paying any remuneration (including any kickback, bribe or certain rebates), directly or indirectly, overtly or covertly, in cash or in kind, to induce or reward either thereferral of an individual for, or the purchase, lease, order or recommendation of, any good, facility, item or service, for which payment may be made, in whole or in part, under U.S. federal and state healthcare programs such as Medicare andMedicaid. A person or entity does not need to have actual knowledge of the statute or specific intent to violate it in order to have committed a violation;

 

  

the U.S. federal civil False Claims Act, which can be enforced through whistleblower actions, and which, amongother things, imposes significant civil penalties, treble damages, and potential exclusion from federal healthcare programs against individuals or entities for knowingly presenting, or causing to be presented, to the U.S. federal government, claimsfor payment or approval that are false or fraudulent, knowingly making, using or causing to be made or used, a false record or statement material to a false or fraudulent claim, or from knowingly making a false statement to avoid, decrease orconceal an obligation to pay money to the U.S. federal government. In addition, the government may assert that a claim resulting from a violation of the U.S. federal Anti-Kickback Statute, U.S. Federal Food, Drug and Cosmetic Act (FDCA), or otherlaw constitutes a false or fraudulent claim for purposes of the civil False Claims Act. There is also the federal criminal False Claims Act, which is similar to the federal civil False Claims Act and imposes criminal liability on those that make orpresent a false, fictitious or fraudulent claim to the federal government;

 

  

the U.S. federal Civil Monetary Penalties Law, which authorizes the imposition of substantial civil monetarypenalties against any person or entity that engages in activities including, among others (1) knowingly presenting, or causing to be presented, a claim for services not provided as claimed or that is otherwise false or fraudulent in any way;(2) arranging for or contracting with an individual or entity that is excluded from participation in federal healthcare programs to provide items or services reimbursable by a federal healthcare program; (3) violations of the federalAnti-Kickback Statute; (4) failing to report and return a known overpayment; or (5) offering or transferring any remuneration to a Medicare or Medicaid beneficiary if the person knows or should know it is likely to influence thebeneficiary’s selection of a particular provider, practitioner, or supplier of items or services reimbursable by Medicare or Medicaid, unless an exception applies;

 

  

the U.S. federal Health Insurance Portability and Accountability Act of 1996 (HIPAA) which imposes criminaland civil liability for, among other things, knowingly and wilfully executing, or attempting to

execute, a scheme to defraud any healthcare benefit program, or knowingly and wilfully falsifying, concealing or covering up a material fact or making any materially false statement, inconnection with the delivery of, or payment for, healthcare benefits, items or services; similar to the U.S. federal Anti-Kickback Statute, a person or entity does not need to have actual knowledge of the statute or specific intent to violate it inorder to have committed a violation;

 

  

the FDCA, which prohibits, among other things, the adulteration or misbranding of drugs, biologics and medicaldevices;

 

  

the U.S. federal Physician Payments Sunshine Act, enacted as part of the Affordable Care Act, and itsimplementing regulations, which requires certain manufacturers of drugs, devices, biologics and medical supplies that are reimbursable under Medicare, Medicaid or the Children’s Health Insurance Program to track and report annually to CMSinformation related to certain payments and other transfers of value provided to U.S.-licensed physicians (defined to include doctors, dentists, optometrists, podiatrists and chiropractors) and teaching hospitals, as well as ownership and investmentinterests held by the physicians described above and their immediate family members. Beginning in January 1, 2022, such obligations will include the reporting of payments and other transfers of value provided in the previous year to certainother healthcare professionals, including physician assistants, nurse practitioners, clinical nurse specialists, certified nurse anesthetists, anesthesiology assistants, and certified nurse midwives;

 

  

analogous state laws and regulations, including: state anti-kickback and false claims laws, which may apply toour business practices, including, but not limited to, research, distribution, sales and marketing arrangements and claims involving healthcare items or services reimbursed by any third-party payor, including private insurers; state laws thatrequire pharmaceutical companies to comply with the pharmaceutical industry’s voluntary compliance guidelines and the relevant compliance guidance promulgated by the U.S. federal government, or otherwise restrict payments that may be made tohealthcare providers and other potential referral sources; state laws and regulations that require drug manufacturers to file reports relating to pricing and marketing information, including information pertaining to and justifying price increases;state laws and regulations that prohibit various marketing-related activities, such as the provision of certain kinds of gifts or meals, or require the tracking and reporting of gifts and other remuneration and items of value provided to healthcareprofessionals and entities; and state and local laws requiring the registration of pharmaceutical sales representatives; and

 

  

European and other foreign law equivalents of each of the laws, including reporting requirements detailinginteractions with and payments to healthcare providers.

Ensuring that our internal operations andfuture business arrangements with third parties comply with applicable healthcare laws and regulations will involve substantial costs. It is possible that governmental authorities will conclude that our business practices, including certainarrangements with physicians who receive stock, warrants or stock options as compensation for services provided to us, do not comply with current or future statutes, regulations, agency guidance or case law involving applicable fraud and abuse orother healthcare laws and regulations. If our operations are found to be in violation of any of the laws described above or any other governmental laws and regulations that may apply to us, we may be subject to significant penalties, includingcivil, criminal and administrative penalties, damages, fines, exclusion from U.S. government funded healthcare programs, such as Medicare and Medicaid, or similar programs in other countries or jurisdictions, disgorgement, imprisonment, contractualdamages, reputational harm, diminished profits, additional reporting requirements and oversight if we become subject to a corporate integrity agreement or similar agreement to resolve allegations ofnon-compliance with these laws and the delay, reduction, termination or restructuring of our operations. Further, defending against any such actions can be costly and time-consuming, and may requiresignificant financial and personnel resources. Therefore, even if we are successful in defending against any such actions that may be brought against us, our business may be impaired. If any of the physicians or other providers or entities with whomwe expect to do business is found to not be in compliance with applicable laws, they may be subject to significant criminal, civil or administrative sanctions, including exclusions from government funded

healthcare programs and imprisonment. If any of the above occur, it could adversely affect our ability to operate our business and our results of operations.

Healthcare legislative reform measures may have a material adverse effect on our business and results of operations

The United States and many foreign jurisdictions have enacted or proposed legislative and regulatory changesaffecting the healthcare system that could prevent or delay marketing approval of our current product candidates and any future product candidates, restrict or regulate post-approval activities and affect our ability to profitably sella product for which we obtain marketing approval. Changes in regulations, statutes or the interpretation of existing regulations could impact our business in the future by requiring, for example: (i) changes to our manufacturing arrangements;(ii) additions or modifications to product labeling; (iii) the recall or discontinuation of our products; or (iv) additional record-keeping requirements. If any such changes were to be imposed, they could adversely affect theoperation of our business.

In the United States, there have been and continue to be a number of legislative initiativesto contain healthcare costs. For example, in March 2010, the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act of 2010 (collectively, the ACA), was passed, which substantially changed the wayhealthcare is financed by both governmental and private insurers, and significantly impacted the U.S. pharmaceutical industry. The ACA, among other things, subjected biological products to potential competition by lower-cost biosimilars, addressed anew methodology by which rebates owed by manufacturers under the Medicaid Drug Rebate Program are calculated for drugs and biologics that are inhaled, infused, instilled, implanted or injected, increased the minimum Medicaid rebates owed bymanufacturers under the Medicaid Drug Rebate Program and extended the rebate program to individuals enrolled in Medicaid managed care organizations, established annual fees and taxes on manufacturers of certain branded prescription drugs andbiologics, and created a new Medicare Part D coverage gap discount program, in which manufacturers must agree to offer 70% (increased from 50% pursuant to the Bipartisan Budget Act of 2018, effective as of 2019) point-of-sale discounts off negotiated prices of applicable brand drugs and biologics to eligible beneficiaries during their coverage gap period, as a condition for the manufacturer’s outpatient drugs orbiologics to be covered under Medicare Part D.

Since its enactment, there have been judicial, executive and Congressionalchallenges to certain aspects of the ACA. On June 17, 2021, the U.S. Supreme Court dismissed the most recent judicial challenge to the ACA brought by several states without specifically ruling on the constitutionality of the ACA. Prior to theSupreme Court’s decision, President Biden issued an executive order to initiate a special enrollment period from February 15, 2021 through August 15, 2021 for purposes of obtaining health insurance coverage through the ACAmarketplace. The executive order also instructed certain governmental agencies to review and reconsider their existing policies and rules that limit access to healthcare, including among others, re-examiningMedicaid demonstration projects and waiver programs that include work requirements, and policies that create unnecessary barriers to obtaining access to health insurance coverage through Medicaid or the ACA. It is unclear how other healthcare reformmeasures of the Biden administration or other efforts, if any, to challenge, repeal or replace the ACA will impact the ACA or our business.

In addition, other legislative changes have been proposed and adopted since the ACA was enacted. On August 2, 2011, theBudget Control Act of 2011 was signed into law, which, among other things, resulted in reductions to Medicare payments to providers of 2% per fiscal year, which went into effect on April 1, 2013 and, due to subsequent legislative amendments tothe statute, will remain in effect through 2030, with the exception of a temporary suspension from May 1, 2020 through December 31, 2021, unless additional Congressional action is taken. On January 2, 2013, the American TaxpayerRelief Act of 2012 was signed into law, which, among other things, reduced Medicare payments to several providers, including hospitals, and increased the statute of limitations period for the government to recover overpayments to providers fromthree to five years.

Further, there has been heightened governmental scrutiny in the UnitedStates of pharmaceutical pricing practices in light of the rising cost of prescription drugs. Such scrutiny has resulted in several recent congressional inquiries and proposed and enacted federal and state legislation designed to, among otherthings, bring more transparency to product pricing, review the relationship between pricing and manufacturer patient programs, and reform government program reimbursement methodologies for products. Although a number of these and other measures mayrequire additional authorization to become effective, Congress and the current U.S. administration have each indicated that it will continue to seek new legislative and/or administrative measures to control drug costs. Any reduction in reimbursementfrom Medicare and other government programs may result in a similar reduction in payments from private payors.

At thestate level, legislatures have increasingly passed legislation and implemented regulations designed to control pharmaceutical and biological product pricing, including price or patient reimbursement constraints, discounts, restrictions on certainproduct access and marketing cost disclosure and transparency measures, and, in some cases, designed to encourage importation from other countries and bulk purchasing. Legally mandated price controls on payment amounts by third-party payors or otherrestrictions could harm our business, results of operations, financial condition and prospects. In addition, regional healthcare authorities and individual hospitals are increasingly using bidding procedures to determine what pharmaceutical productsand which suppliers will be included in their prescription drug and other healthcare programs. This could reduce the ultimate demand for our product candidates, if approved, or put pressure on our product pricing, which could negatively affect ourbusiness, results of operations, financial condition and prospects.

We expect that the ACA, these new laws, and otherhealthcare reform measures that may be adopted in the future may result in additional reductions in Medicare and other healthcare funding, more rigorous coverage criteria, new payment methodologies and additional downward pressure on the price thatwe receive for any approved product. The implementation of cost containment measures or other healthcare reforms may prevent us from being able to generate revenue, attain profitability, or commercialize or product candidates, if approved.

We are subject to a variety of privacy and data security laws, and our failure to comply with them could harm ourbusiness.

We maintain a large quantity of sensitive information, including confidential business and personalinformation in connection with the conduct of our clinical trials and related to our employees, and we are subject to laws and regulations governing the privacy and security of such information. In the United States, there are numerous federal andstate privacy and data security laws and regulations governing the collection, use, disclosure and protection of personal information, including federal and state health information privacy laws, federal and state security breach notification laws,and federal and state consumer protection laws. The legislative and regulatory landscape for privacy and data protection continues to evolve, and there has been an increasing focus on privacy and data protection issues, including with respect toregulatory enforcement and private litigation, which may affect our business and is expected to increase our compliance costs and exposure to liability. In the United States, numerous federal and state laws and regulations could apply to ouroperations or the operations of our partners, including state data breach notification laws, state health information privacy laws, and federal and state consumer protection laws and regulations (e.g. Section 5 of the FTC Act), that govern thecollection, use, disclosure, and protection of health-related and other personal information. In addition, we may obtain health information from third parties (including research institutions from which we obtain clinical trial data) that aresubject to privacy and security requirements under HIPAA, as amended by HITECH and regulations promulgated thereunder. Depending on the facts and circumstances, we could be subject to significant penalties if we obtain, use, or disclose, or aresubject to an actual or alleged data breach regarding, individually identifiable health information in a manner that is not authorized or permitted by HIPAA.

In the EEA, we are subject to the EU General Data Protection Regulation (the EU GDPR), which took effect in May 2018. The EUGDPR governs the collection, use, disclosure, transfer or other processing of personal data (i.e., data which identifies an individual or from which an individual is identifiable), including clinical trial data,

 

50


Table of Contents

and grants individuals various data protection rights (e.g., the right to erasure of personal data). The EU GDPR imposes a number of obligations on companies, including inter alia:(i) accountability and transparency requirements, and enhanced requirements for obtaining valid consent; (ii) obligations to consider data protection as any new products or services are developed and to limit the amount of personal dataprocessed; and (iii) obligations to implement appropriate technical and organizational measures to safeguard personal data and to report certain personal data breaches to the supervisory authority without undue delay (and no later than 72 hourswhere feasible). In addition, the EU GDPR prohibits the transfer of personal data from the EEA to the United States and other jurisdictions that the European Commission does not recognize as having “adequate” data protection laws unless adata transfer mechanism has been put in place. In July 2020, the Court of Justice of the EU (CJEU) limited how organizations could lawfully transfer personal data from the EEA to the United States by invalidating theEU-US Privacy Shield for purposes of international transfers and imposing further restrictions on use of the standard contractual clauses (SCCs) including, a requirement for companies to carry out a transferprivacy impact assessment, which among other things, assesses laws governing access to personal data in the recipient country and considers whether supplementary measures that provide privacy protections additional to those provided under SCCs willneed to be implemented to ensure an essentially equivalent level of data protection to that afforded in the EEA. The European Commission subsequently issued new SCCs in June 2021 to account for the decision of the CJEU and recommendations made bythe European Data Protection Board and which are in turn relatively more onerous. The EU GDPR imposes substantial fines for breaches and violations (up to the greater of €20 million or 4% of consolidated annual worldwide gross revenue),and confers a private right of action on data subjects and consumer associations to lodge complaints with supervisory authorities, seek judicial remedies and obtain compensation for damages resulting from violations of the EU GDPR. Relatedly,following the United Kingdom’s withdrawal from the EU (i.e., Brexit), and the expiry of the Brexit transition period, which ended on December 31, 2020, the EU GDPR has been implemented in the United Kingdom (as the UK GDPR). The UK GDPRsits alongside the UK Data Protection Act 2018 which implements certain derogations in the EU GDPR into UK law. Under the UK GDPR, companies not established in the UK but who process personal data in relation to the offering of goods or services toindividuals in the UK, or to monitor their behavior will be subject to the UK GDPR – the requirements of which are (at this time) largely aligned with those under the EU GDPR and as such, may lead to similar compliance and operational costswith potential fines of up to £17.5 million or 4% of global turnover.

Compliance with these and any otherapplicable privacy and data security laws and regulations is a rigorous and time-intensive process, and we may be required to put in place additional mechanisms ensuring compliance with the new data protection rules. Furthermore, the laws are notconsistent, and compliance in the event of a widespread data breach is costly. In addition, states are constantly adopting new laws or amending existing laws, requiring attention to frequently changing regulatory requirements. For example,California enacted the California Consumer Privacy Act (the CCPA), which took effect on January 1, 2020, became enforceable by the California Attorney General on July 1, 2020, and has been dubbed the first “GDPR-like” law in theUnited States. The CCPA gives California residents expanded rights to access and delete their personal information, opt out of certain personal information sharing and receive detailed information about how their personal information is used byrequiring covered companies to provide new disclosures to California consumers (as that term is broadly defined) and provide such consumers new ways to opt-out of certain sales of personal information. TheCCPA provides for civil penalties for violations, as well as a private right of action for data breaches that is expected to increase data breach litigation. Further, the California Privacy Rights Act (the CPRA) recently passed in California. TheCPRA will impose additional data protection obligations on companies doing business in California, including additional consumer rights processes, limitations on data uses, new audit requirements for higher risk data, and opt outs for certain usesof sensitive data. It will also create a new California data protection agency authorized to issue substantive regulations and could result in increased privacy and information security enforcement. The majority of the provisions will go into effecton January 1, 2023, and additional compliance investment and potential business process changes may be required. Although the CCPA currently exempts certain health-related information, including clinical trial data, the CCPA and the CPRA mayincrease our compliance costs and potential liability. Similar laws have been adopted in other states (for example Nevada,

 

51


Table of Contents

Virginia and Colorado) or proposed in other states and at the federal level, and if passed, such laws may have potentially conflicting requirements that would make compliance challenging.

Any actual or perceived failure by us to comply with applicable privacy and data security laws and regulations could result inregulatory investigations, reputational damage, orders to cease/ change our processing of our data, enforcement notices, and/ or assessment notices (for a compulsory audit). We may also face civil claims including representative actions and otherclass action type litigation (where individuals have suffered harm), potentially amounting to significant compensation or damages liabilities, as well as associated costs, diversion of internal resources, and reputational harm.

Risks Related to Intellectual Property

If we are unable to obtain and maintain sufficient intellectual property protection for our platform technologies andproduct candidates, or if the scope of the intellectual property protection is not sufficiently broad, our competitors could develop and commercialize products similar or identical to ours, and our ability to successfully commercialize our productsmay be adversely affected.

We rely upon a combination of patents, know-howand confidentiality agreements to protect the intellectual property related to our products and technologies and to prevent third parties from copying and surpassing our achievements, thus eroding our competitive position in our market.

Our success depends in large part on our ability to obtain and maintain patent protection for our T-win technology platform, product candidates and their uses, as well as our ability to operate without infringing the proprietary rights of others. We seek to protect our proprietary position by filing patentapplications in the United States and abroad related to our novel discoveries and technologies that are important to our business. We cannot guarantee that our pending and future patent applications will result in patents being issued or that issuedpatents will afford sufficient protection of our product candidates or their intended uses against competitors, nor can there be any assurance that the patents issued will not be infringed, designed around, invalidated by third parties, or willeffectively prevent others from commercializing competitive technologies, products or product candidates.

Obtaining andenforcing patents is expensive and time-consuming, and we may not be able to file and prosecute all necessary or desirable patent applications or maintain and/or enforce patents that may issue based on our patent applications, at a reasonable costor in a timely manner, including delays as a result of the COVID-19 pandemic impacting our or our licensors’ operations. It is also possible that we will fail to identify patentable aspects of ourresearch and development results before it is too late to obtain patent protection. Although we enter into non-disclosure and confidentiality agreements with parties who have access to patentable aspects ofour research and development output, such as our employees, corporate collaborators, outside scientific collaborators, contract research organizations, contract manufacturers, consultants, advisors and other third parties, any of these parties maybreach these agreements and disclose such results before a patent application is filed, thereby jeopardizing our ability to seek patent protection.

Composition of matter patents for biological and pharmaceutical product candidates often provide a strong form of intellectualproperty protection for those types of products, as such patents provide protection without regard to any method of use. However, we cannot be certain that the claims in our pending patent applications directed to composition of matter of ourproduct candidates will be considered patentable by the United States Patent and Trademark Office (USPTO) or by patent offices in foreign countries, or that the claims in any of our issued patents will be considered valid and enforceable by courtsin the United States or foreign countries. Method of use patents protect the use of a product for the specified method. This type of patent does not prevent a competitor from making and marketing a product that is identical to our product for anindication that is outside the scope of the patented method. Moreover, even if competitors do not actively promote their product for our targeted indications, physicians may prescribe these products“off-label.” Although off-label prescriptions may

infringe or contribute to the infringement of method of use patents, the practice is common and such infringement is difficult to prevent or prosecute.

The patent position of biopharmaceutical companies generally is highly uncertain, involves complex legal, scientific, andfactual questions and has in recent years been the subject of much litigation, resulting in court decisions, including Supreme Court decisions, which have increased uncertainties as to the ability to enforce patent rights in the future. Thestandards that the USPTO and its foreign counterparts use to grant patents are not always applied predictably or uniformly. In addition, the laws of foreign countries may not protect our rights to the same extent as the laws of the United States, orvice versa.

The patent application process is subject to numerous risks and uncertainties, and there can be no assurancethat we or any of our potential future collaborators will be successful in protecting our product candidates by obtaining and defending patents. For example, we may not be aware of all third-party intellectual property rights potentially relating toour product candidates or their intended uses, and as a result the impact of such third-party intellectual property rights upon the patentability of our own patents and patent applications, as well as the impact of such third-party intellectualproperty upon our freedom to operate, is highly uncertain. Patent applications in the United States and other jurisdictions are typically not published until 18 months after filing or, in some cases, not at all. Therefore, we cannot know withcertainty whether we were the first to make the inventions claimed in our patents or pending patent applications, or that we were the first to file for patent protection of such inventions. As a result, the issuance, inventorship, scope, validity,enforceability and commercial value of our patent rights are highly uncertain. Our pending patent applications may be challenged in patent offices in the United States and abroad. The issuance of a patent is not conclusive as to its inventorship,ownership, scope, validity or enforceability. Even issued patents may later be found invalid or unenforceable or may be modified or revoked in proceedings instituted by third parties before various patent offices or in courts. For example, ourpending patent applications may be subject to third-party pre-issuance submissions of prior art to the USPTO or our issued patents may be subject to post-grant review (PGR) proceedings, oppositions,derivations, reexaminations, interference or inter partes review proceedings, in the United States or elsewhere, challenging our patent rights or the patent rights of others. An adverse determination in any such challenges may result in lossof exclusivity or in patent claims being narrowed, invalidated, or held unenforceable, in whole or in part, which could limit our ability to stop others from using or commercializing similar or identical technology and products, or limit theduration of the patent protection of our technology and products. In addition, given the amount of time required for the development, testing and regulatory review of new product candidates, patents protecting such candidates might expire before orshortly after such candidates are commercialized. The degree of future protection for our proprietary rights is uncertain. Only limited protection may be available and may not adequately protect our rights or permit us to gain or keep anycompetitive advantage. Any failure to obtain or maintain patent protection with respect to our product candidates or their uses could have a material adverse effect on our business, financial condition, results of operations and prospects.

In addition to the protection afforded by patents, we rely on trade secret protection and confidentiality agreements toprotect proprietary know-how that is not patentable, processes for which patents are difficult to enforce and any other elements of our discovery and development processes that involve proprietary know-how, information or technology that is not covered by patents. We may also rely on trade secret protection as temporary protection for concepts that may be included in a future patent filing. However, tradesecret protection will not protect us from innovations that a competitor develops independently of our proprietary know how. If a competitor independently develops a technology that we protect as a trade secret and files a patent application on thattechnology, then we may not be able to patent that technology in the future, may require a license from the competitor to use our own know-how, and if the license is not available on commercially-viable terms,then we may not be able to launch our product. Although we require all of our employees to assign their inventions to us, and require all of our employees, consultants, advisors and any third parties who have access to our proprietary know-how, information or technology to enter into confidentiality agreements, we cannot be certain that our trade secrets and other confidential proprietary information will not be disclosed or that competitors willnot otherwise gain access to our trade secrets or independently develop substantially equivalent information and

techniques. Furthermore, the laws of some foreign countries do not protect proprietary rights to the same extent or in the same manner as the laws of the United States. As a result, we mayencounter significant problems in protecting and defending our intellectual property both in the United States and abroad. If we are unable to prevent unauthorized material disclosure of our intellectual property to third parties, we will not beable to establish or maintain a competitive advantage in our market, and this scenario could materially adversely affect our business, financial condition and results of operations.

Intellectual property rights do not necessarily address all potential threats to our competitive advantage.

The degree of future protection afforded by our intellectual property rights is uncertain because intellectual property rightshave limitations and may not adequately protect our business or permit us to maintain our competitive advantage. For example:

 

  

others may be able to make product candidates that are the same as or similar to ours but that are not coveredby the claims of the patents that we own or have exclusively licensed;

 

  

we or our licensors or future collaborators might not have been the first to make the inventions covered bythe issued patent or pending patent application that we own or have exclusively licensed;

 

  

we or our licensors or future collaborators might not have been the first to file patent applications coveringcertain of our inventions;

 

  

others may independently develop similar or alternative technologies or duplicate any of our technologieswithout infringing our intellectual property rights;

 

  

it is possible that noncompliance with the USPTO and foreign governmental patent agencies requirement for anumber of procedural, documentary, fee payment and other provisions during the patent process can result in abandonment or lapse of a patent or patent application, and partial or complete loss of patent rights in the relevant jurisdiction;

 

  

it is possible that our pending patent applications will not lead to issued patents;

 

  

issued patents that we own or have exclusively licensed may be revoked, modified, or held invalid orunenforceable, as a result of legal challenges by our competitors;

 

  

our competitors might conduct research and development activities in countries where we do not have patentrights and then use the information learned from such activities to develop competitive products for sale in our major commercial markets;

 

  

we may not develop additional proprietary technologies that are patentable;

 

  

we cannot predict the scope of protection of any patent issuing based on our patent applications, includingwhether the patent applications that we own or in-license will result in issued patents with claims that directed to our product candidates or uses thereof in the United States or in other foreign countries;

 

  

there may be significant pressure on the U.S. government and international governmental bodies to limit thescope of patent protection both inside and outside the United States for disease treatments that prove successful, as a matter of public policy regarding worldwide health concerns;

 

  

countries other than the United States may have patent laws less favorable to patentees than those upheld byU.S. courts, allowing foreign competitors a better opportunity to create, develop and market competing product candidates;

 

  

the claims of any patent issuing based on our patent applications may not provide protection againstcompetitors or any competitive advantages, or may be challenged by third parties;

 

  

if enforced, a court may not hold that our patents are valid, enforceable and infringed;

 

54


Table of Contents
  

we may need to initiate litigation or administrative proceedings to enforce and/or defend our patent rightswhich will be costly whether we win or lose;

 

  

we may choose not to file a patent application in order to maintain certain trade secrets or know-how, and a third party may subsequently file a patent application covering such intellectual property;

 

  

we may fail to adequately protect and police our trademarks and trade secrets; and

 

  

the patents of others may have an adverse effect on our business, including if others obtain patents claimingsubject matter similar to or improving that covered by our patents and patent applications.

Should anyof these or similar events occur, they could significantly harm our business, results of operations and prospects.

If we fail to comply with our obligations imposed by any intellectual property licenses with third parties that we mayneed in the future, we could lose rights that are important to our business.

We may in the future require licensesto third-party technology and materials. Such licenses may not be available in the future or may not be available on commercially reasonable terms, or at all, which could have a material adverse effect on our business and financial condition. We mayrely on third parties from whom we license proprietary technology to file and prosecute patent applications and maintain patents and otherwise protect the intellectual property we license from them. We may have limited control over these activitiesor any other intellectual property that may be related to our in-licensed intellectual property. For example, we cannot be certain that such activities by these licensors will be conducted in compliance withapplicable laws and regulations or will result in valid and enforceable patents and other intellectual property rights. We may have limited control over the manner in which our licensors initiate an infringement proceeding against a third-partyinfringer of the intellectual property rights, or defend certain of the intellectual property that may be licensed to us. It is possible that the licensors’ infringement proceeding or defense activities may be less vigorous than if we conductthem ourselves. Even if we acquire the right to control the prosecution, maintenance and enforcement of the licensed and sublicensed intellectual property relating to our product candidates, we may require the cooperation of our licensors and anyupstream licensor, which may not be forthcoming. Therefore, we cannot be certain that the prosecution, maintenance and enforcement of these patent rights will be in a manner consistent with the best interests of our business. If we or our licensorfail to maintain such patents, or if we or our licensor lose rights to those patents or patent applications, the rights we have licensed may be reduced or eliminated and our right to develop and commercialize any of our product candidates that arethe subject of such licensed rights could be adversely affected. In addition to the foregoing, the risks associated with patent rights that we license from third parties will also apply to patent rights we may own in the future. Further, if we failto comply with our diligence, development and commercialization timelines, milestone payments, royalties, insurance and other obligations under our license agreements, we may lose our patent rights with respect to such agreement, which would affectour patent rights worldwide.

Termination of our current or any future license agreements would reduce or eliminate ourrights under these agreements and may result in our having to negotiate new or reinstated agreements with less favorable terms or cause us to lose our rights under these agreements, including our rights to important intellectual property ortechnology. Any of the foregoing could prevent us from commercializing our other product candidates, which could have a material adverse effect on our operating results and overall financial condition.

In addition, intellectual property rights that we in-license in the future may besublicenses under intellectual property owned by third parties, in some cases through multiple tiers. The actions of our licensors may therefore affect our rights to use our sublicensed intellectual property, even if we are in compliance with all ofthe obligations under our license agreements. Should our licensors or any of the upstream licensors fail to comply with their obligations under the agreements pursuant to which they obtain the rights that are sublicensed to us, or should suchagreements be terminated or amended, our ability to develop and commercialize our product candidates may be materially harmed.

In the future, we may need to obtain additional licenses ofthird-party technology that may not be available to us or are available only on commercially unreasonable terms, and which may cause us to operate our business in a more costly or otherwise adverse manner that was not anticipated.

We currently own intellectual property directed to our product candidates and other proprietary technologies, including our T-win technology platform. Other pharmaceutical companies and academic institutions may also have filed or are planning to file patent applications potentially relevant to our business. From time to time, in orderto avoid infringing these third-party patents, we may be required to license technology from additional third parties to further develop or commercialize our product candidates. Should we be required to obtain licenses to any third-party technology,including any such patents required to manufacture, use or sell our product candidates, such licenses may not be available to us on commercially reasonable terms, or at all. The inability to obtain any third-party license required to develop orcommercialize any of our product candidates could cause us to abandon any related efforts, which could seriously harm our business and operations.

The licensing or acquisition of third-party intellectual property rights is a competitive area, and several more establishedcompanies may pursue strategies to license or acquire third-party intellectual property rights we may consider attractive or necessary. These established companies may have a competitive advantage over us due to their size, capital resources andgreater clinical development and commercialization capabilities. In addition, companies that perceive us to be a competitor may be unwilling to assign or license rights to us. Even if we are able to obtain a license under such intellectual propertyrights, any such license may be non-exclusive, which may allow our competitors access to the same technologies licensed to us.

Moreover, some of our owned and in-licensed patents or patent applications or futurepatents may be co-owned with third parties. If we are unable to obtain an exclusive license to any such third-party co-owners’ interest in such patents or patentapplications, such co-owners may be able to license their rights to other third parties, including our competitors, and our competitors could market competing products and technology. In addition, we may needthe cooperation of any such co-owners of our patents in order to enforce such patents against third parties, and such cooperation may not be provided to us. Furthermore, our owned and in-licensed patents maybe subject to a reservation of rights by one or more third parties. Any of the foregoing could have a material adverse effect on our competitive position, business, financial conditions,results of operations and prospects.

If we are sued for infringing intellectual property rights of third parties,such litigation could be costly and time consuming and could prevent or delay us from developing or commercializing our product candidates.

Our commercial success depends, in part, on our ability to develop, manufacture, market and sell our product candidates withoutinfringing the intellectual property and other proprietary rights of third parties. Third parties may allege that we have infringed, misappropriated or otherwise violated their intellectual property. Litigation or other legal proceedings relating tointellectual property claims, with or without merit, is unpredictable and generally expensive and time consuming and, even if resolved in our favor, is likely to divert significant resources from our core business, including distracting ourtechnical and management personnel from their normal responsibilities. In addition, there could be public announcements of the results of hearings, motions or other interim proceedings or developments and if securities analysts or investors perceivethese results to be negative, it could have a substantial adverse effect on the market price of our common stock. Such litigation or proceedings could substantially increase our operating losses and reduce the resources available for developmentactivities or any future sales, marketing or distribution activities. We may not have sufficient financial or other resources to adequately conduct such litigation or proceedings. Some of our competitors may be able to sustain the costs of suchlitigation or proceedings more effectively than we can because of their greater financial resources and more mature and developed intellectual property portfolios. Uncertainties resulting from the initiation and continuation of patent litigation orother proceedings could have a material adverse effect on our

ability to compete in the marketplace. In addition, patent holding companies that focus solely on extracting royalties and settlements by enforcing patent rights may target us.

There is a substantial amount of intellectual property litigation in the biotechnology and pharmaceutical industries, and wemay become party to, or threatened with, litigation or other adversarial proceedings regarding intellectual property rights with respect to our product candidates. We cannot be certain that our product candidates and other proprietary technologieswe may develop will not infringe existing or future patents owned by third parties. Third parties may assert infringement claims against us based on existing or future intellectual property rights. If we are found to infringe a third party’sintellectual property rights, we could be forced, including by court order, to cease developing, manufacturing or commercializing the infringing candidate product or product. Alternatively, we may be required to obtain a license from such thirdparty in order to use the infringing technology and continue developing, manufacturing or marketing the infringing candidate product or product. However, we may not be able to obtain any required license on commercially reasonable terms or at all.Even if we were able to obtain a license, it could be non-exclusive, thereby giving our competitors access to the same technologies licensed to us. In addition, we could be found liable for monetary damages,including treble damages and attorneys’ fees if we are found to have willfully infringed a patent. A finding of infringement could prevent us from commercializing our investigational products or force us to cease some of our businessoperations, which could materially harm our business. Claims that we have misappropriated the confidential information or trade secrets of third parties could have a similar negative impact on our business.

We cannot guarantee that any of our or our licensors’ patent searches or analyses, including but not limited to theidentification of relevant patents, analysis of the scope of relevant patent claims or determination of the expiration of relevant patents, are complete or thorough. We may not be aware of patents that have already been issued and that a thirdparty, for example, a competitor in the fields in which we are developing our product candidates, might assert are infringed by our current or future product candidates, including claims to compositions, formulations, methods of manufacture ormethods of use or treatment that cover our product candidates. It is also possible that patents owned by third parties of which we are aware, but which we do not believe are relevant to our product candidates and other proprietary technologies wemay develop, could be found to be infringed by our product candidate. In addition, because patent applications can take many years to issue, there may be currently pending patent applications that may later result in issued patents that our productcandidates may infringe. Additionally, pending patent applications that have been published can, subject to certain limitations, be later amended in a manner that could cover our product candidates or the use of our product candidates. . Ourdetermination of the expiration date of any patent in the United States, Europe or elsewhere that we consider relevant may be incorrect, which may negatively impact our ability to develop and market our product candidates. Our competitors in boththe United States and abroad, many of which have substantially greater resources and have made substantial investments in patent portfolios and competing technologies, may have applied for or obtained or may in the future apply for and obtain,patents that will prevent, limit or otherwise interfere with our ability to make, use and sell our product candidates. The pharmaceutical and biotechnology industries have produced a considerable number of patents, and it may not always be clear toindustry participants, including us, which patents cover various types of products or methods of use. The coverage of patents is subject to interpretation by the courts, and the interpretation is not always uniform. If we were sued for patentinfringement, we would need to demonstrate that our product candidates, products or methods either do not infringe the patent claims of the relevant patent or that the patent claims are invalid or unenforceable, and we may not be able to do this.Proving invalidity may be difficult. For example, in the United States, proving invalidity in court requires a showing of clear and convincing evidence to overcome the presumption of validity enjoyed by issued patents, and there is no assurance thata court of competent jurisdiction would invalidate the claims of any such U.S. patent. Even if we are successful in these proceedings, we may incur substantial costs and the time and attention of our management and scientific personnel could bediverted in pursuing these proceedings, which could have a material adverse effect on our business and operations. Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation, there is arisk that some of our confidential information could be compromised by disclosure

during litigation. In addition, we may not have sufficient resources to bring these actions to a successful conclusion.

We may choose to challenge the enforceability or validity of claims in a third party’s U.S. patent by requesting that theUSPTO review the patent claims in an ex-parte re-exam, inter partes review or post-grant review proceedings. These proceedings are expensive and mayconsume our time or other resources. We may choose to challenge a third party’s patent in patent opposition proceedings in the European Patent Office (EPO), or other foreign patent office. The costs of these opposition proceedings could besubstantial, and may consume our time or other resources. If we fail to obtain a favorable result at the USPTO, EPO or other patent office then we may be exposed to litigation by a third party alleging that the patent may be infringed by our productcandidates or proprietary technologies.

We may become involved in lawsuits to protect or enforce our patents orother intellectual property, which could be expensive, time consuming and unsuccessful.

Competitors or other thirdparties may infringe our patents, trademarks or other intellectual property. To counter infringement or unauthorized use, we may be required to file infringement claims, which can be expensive and time consuming and divert the time and attention ofour management and scientific personnel. Our pending patent applications cannot be enforced against third parties practicing the technology claimed in such applications unless and until a patent issues from such applications. Any claims we assertagainst perceived infringers could provoke these parties to assert counterclaims against us alleging that we infringe their patents, in addition to counterclaims asserting that our patents are invalid or unenforceable, or both. In patent litigationin the United States, defendant counterclaims alleging invalidity or unenforceability are commonplace. Grounds for a validity challenge could be an alleged failure to meet any of several statutory requirements, including lack of novelty,obviousness, non-enablement or insufficient written description. Grounds for an unenforceability assertion could be an allegation that someone connected with prosecution of the patent withheld relevantinformation from the USPTO or made a misleading statement during prosecution. The outcome following legal assertions of invalidity and unenforceability is unpredictable. In any patent infringement proceeding, there is a risk that a court will decidethat a patent of ours is invalid or unenforceable, in whole or in part, and that we do not have the right to stop the other party from using the invention at issue. There is also a risk that, even if the validity of such patents is upheld, the courtwill construe the patent’s claims narrowly or decide that we do not have the right to stop the other party from using the invention at issue on the grounds that our patent claims do not cover the invention, or decide that the other party’suse of our patented technology falls under the safe harbor to patent infringement under 35 U.S.C. §271(e)(1). An adverse outcome in a litigation or proceeding involving our patents could limit our ability to assert our patents against thoseparties or other competitors and may curtail or preclude our ability to exclude third parties from making and selling similar or competitive products. Any of these occurrences could adversely affect our competitive business position, businessprospects and financial condition. Similarly, if we assert trademark infringement claims, a court may determine that the marks we have asserted are invalid or unenforceable, or that the party against whom we have asserted trademark infringement hassuperior rights to the marks in question. In this case, we could ultimately be forced to cease use of such trademarks.

Even if we establish infringement, the court may decide not to grant an injunction against further infringing activity andinstead award only monetary damages, which may or may not be an adequate remedy. Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation, there is a risk that some of our confidentialinformation could be compromised by disclosure during litigation. There could also be public announcements of the results of hearings, motions or other interim proceedings or developments. If securities analysts or investors perceive these resultsto be negative, it could have a material adverse effect on the price of shares of our common stock. Moreover, we cannot assure you that we will have sufficient financial or other resources to file and pursue such infringement claims, which typicallylast for years before they are concluded. Even if we ultimately prevail in such claims, the monetary cost of such litigation and the diversion of the attention of our management and scientific personnel could outweigh any benefit we receive as aresult of the proceedings.

Because of the expense and uncertainty of litigation, we may not be ina position to enforce our intellectual property rights against third parties.

Because of the expense anduncertainty of litigation, we may conclude that even if a third party is infringing our issued patent, any patents that may be issued as a result of our pending or future patent applications or other intellectual property rights, the risk-adjustedcost of bringing and enforcing such a claim or action may be too high or not in the best interest of our company or our stockholders. In such cases, we may decide that the more prudent course of action is to simply monitor the situation or initiateor seek some other non-litigious action or solution.

We may be subject toclaims that our employees, consultants, or independent contractors have wrongfully used or disclosed confidential information of third parties.

We employ and may employ individuals who were previously employed at other biotechnology or pharmaceutical companies, includingour competitors or potential competitors. Although we try to ensure that our employees, consultants and advisors do not use the proprietary information or know-how of others in their work for us, we may besubject to claims that we or our employees, consultants, or independent contractors have inadvertently or otherwise used or disclosed confidential information of our employees’ former employers or other third parties. We may also be subject toclaims that former employers or other third parties have an ownership interest in our future patents. Litigation may be necessary to defend against these claims. If we fail in defending any such claims, in addition to paying monetary damages, we maylose valuable intellectual property rights or personnel. There is no guarantee of success in defending these claims, and even if we are successful, litigation could result in substantial cost and be a distraction to our management and otheremployees.

Changes in patent law in the United States and other jurisdictions could diminish the value of patentsin general, thereby impairing our ability to protect our product candidates.

As is the case with otherbiopharmaceutical companies, our success is heavily dependent on intellectual property, particularly patents. Obtaining and enforcing patents in the biopharmaceutical industry involves both technological and legal complexity and is therefore costly,time consuming and inherently uncertain. Changes in either the patent laws or interpretation of the patent laws in the United States could increase the uncertainties and costs, and may diminish our ability to protect our inventions, obtain,maintain, and enforce our intellectual property rights and, more generally, could affect the value of our intellectual property or narrow the scope of our owned and licensed patents. Patent reform legislation in the United States and othercountries, including the Leahy-Smith America Invents Act (the Leahy-Smith Act), signed into law on September 16, 2011, could increase those uncertainties and costs surrounding the prosecution of our patent applications and the enforcement ordefense of our issued patents. The Leahy-Smith Act includes a number of significant changes to U.S. patent law. These include provisions that affect the way patent applications are prosecuted, redefine prior art and provide more efficient andcost-effective avenues for competitors to challenge the validity of patents. These include allowing third-party submission of prior art to the USPTO during patent prosecution and additional procedures to attack the validity of a patent by USPTOadministered post-grant proceedings, including post-grant review, inter partes review, and derivation proceedings. Further, because of a lower evidentiary standard in these USPTO post-grant proceedings compared to the evidentiary standard inUnited States federal courts necessary to invalidate a patent claim, a third party could potentially provide evidence in a USPTO proceeding sufficient for the USPTO to hold a claim invalid even though the same evidence would be insufficient toinvalidate the claim if first presented in a district court action. Accordingly, a third party may attempt to use the USPTO procedures to invalidate our patent claims that would not have been invalidated if first challenged by the third party as adefendant in a district court action. Thus, the Leahy-Smith Act and its implementation could increase the uncertainties and costs surrounding the prosecution of our patent applications and the enforcement or defense of our issued patents, all ofwhich could have a material adverse effect on our business, financial condition, results of operations and prospects.

After March 2013, under the Leahy-Smith Act, the United States transitionedto a first inventor to file system in which, assuming that the other statutory requirements are met, the first inventor to file a patent application will be entitled to the patent on an invention regardless of whether a third-party was the first toinvent the claimed invention. A third party that files a patent application in the USPTO after March 2013, but before we file an application covering the same invention, could therefore be awarded a patent covering an invention of ours even if wehad made the invention before it was made by such third party. This will require us to be cognizant going forward of the time from invention to filing of a patent application, but circumstances could prevent us from promptly filing patentapplications on our inventions. Since patent applications in the United States and most other countries are confidential for a period of time after filing or until issuance, we cannot be certain that we or our licensors were the first to either(i) file any patent application related to our product candidates and other proprietary technologies we may develop or (ii) invent any of the inventions claimed in our or our licensor’s patents or patent applications. Even where wehave a valid and enforceable patent, we may not be able to exclude others from practicing the claimed invention where the other party can show that they used the invention in commerce before our filing date. Thus the Leahy-Smith Act and itsimplementation could increase the uncertainties and costs surrounding the prosecution of our patent applications and the enforcement or defense of our issued patents, all of which could have a material adverse effect on our business, financialcondition, results of operations and prospects.

In addition, the patent positions of companies in the development andcommercialization of biologics and pharmaceuticals are particularly uncertain. The U.S. Supreme Court has ruled on several patent cases in recent years, either narrowing the scope of patent protection available in certain circumstances or weakeningthe rights of patent owners in certain situations. Depending on future actions by the U.S. Congress, the U.S. courts, the USPTO and the relevant law-making bodies in other countries, the laws and regulationsgoverning patents could change in unpredictable ways that would weaken our ability to obtain new patents or to enforce our existing patents and patents that we might obtain in the future. For example, in the 2013 case Assoc. for MolecularPathology v. Myriad Genetics, Inc., the U.S. Supreme Court held that certain claims to DNA molecules are not patentable. While we do not believe that any of the patents owned or licensed by us will be found invalid based on this decision, wecannot predict how future decisions by the courts, the U.S. Congress or the USPTO may impact the value of our patents.

Obtaining and maintaining patent protection depends on compliance with various procedural, document submissions, feepayment and other requirements imposed by governmental patent agencies, and our patent protection could be reduced or eliminated for non-compliance with these requirements.

Periodic maintenance fees, renewal fees, annuities fees and various other governmental fees on patents and/or patentapplications are due to be paid to the USPTO and foreign patent agencies in several stages over the lifetime of the patent and/or patent application. The USPTO and various foreign governmental patent agencies also require compliance with a number ofprocedural, documentary, fee payment and other similar provisions during the patent application process. While an inadvertent lapse, including due to the effect of the COVID-19 pandemic on us or our patentmaintenance vendors, can in many cases be cured by payment of a late fee or by other means in accordance with the applicable rules, there are situations in which noncompliance can result in abandonment or lapse of the patent or patent application,resulting in partial or complete loss of patent rights in the relevant jurisdiction. Non-compliance events that could result in abandonment or lapse of a patent or patent application include, but are notlimited to, failure to respond to official actions within prescribed time limits, non-payment of fees and failure to properly legalize and submit formal documents. If we fail to maintain the patents and patentapplications covering our product candidates, our competitive position would be adversely affected.

Patent termsmay be inadequate to protect our competitive position on our product candidates for an adequate amount of time.

The term of any individual patent depends on applicable law in the country where the patent is granted. In the United States,provided all maintenance fees are timely paid, a patent generally has a term of 20 years from

 

60


Table of Contents

its application filing date or earliest claimed non-provisional filing date. Extensions may be available under certain circumstances, but the life of apatent and, correspondingly, the protection it affords is limited. Even if we or our licensors obtain patents covering our product candidates, when the terms of all patents covering a product expire, our business may become subject to competitionfrom competitive medications, including generic medications. Given the amount of time required for the development, testing and regulatory review and approval of new product candidates, patents protecting such candidates may expire before or shortlyafter such candidates are commercialized. As a result, our owned and licensed patent portfolio may not provide us with sufficient rights to exclude others from commercializing products similar or identical to ours.

If we do not obtain patent term extension in the United States under the Hatch-Waxman Act and in foreign countries undersimilar legislation, thereby potentially extending the term of marketing exclusivity for our product candidates, our business may be harmed.

In the United States, a patent that covers an FDA-approved drug or biologic may beeligible for a term extension designed to restore the period of the patent term that is lost during the premarket regulatory review process conducted by the FDA. Depending upon the timing, duration and conditions of FDA marketing approval of ourproduct candidates, one or more of our U.S. patents may be eligible for limited patent term extension under the Drug Price Competition and Patent Term Restoration Act of 1984 (the Hatch-Waxman Act), which permits a patent term extension of up tofive years for a patent covering an approved product as compensation for effective patent term lost during product development and the FDA regulatory review process. A patent term extension cannot extend the remaining term of a patent beyond a totalof 14 years from the date of product approval, and only claims covering such approved drug product, a method for using it or a method for manufacturing it may be extended. In Europe, our product candidates may be eligible for term extensions basedon similar legislation. In either jurisdiction, however, we may not receive an extension if we fail to apply within applicable deadlines, fail to apply prior to expiration of relevant patents or otherwise fail to satisfy applicable requirements.Even if we are granted such extension, the duration of such extension may be less than our request. If we are unable to obtain a patent term extension, or if the term of any such extension is less than our request, the period during which we canenforce our patent rights for that product will be in effect shortened and our competitors may obtain approval to market competing products sooner. The resulting reduction of years of revenue from applicable products could be substantial.

We enjoy only limited geographical protection with respect to certain patents and we may not be able to protect ourintellectual property rights throughout the world.

Filing, prosecuting and defending patents covering our productcandidates in all countries throughout the world would be prohibitively expensive, and even in countries where we have sought protection for our intellectual property, such protection can be less extensive than those in the United States. Therequirements for patentability may differ in certain countries, particularly developing countries, and the breadth of patent claims allowed can be inconsistent. In addition, the laws of some foreign countries do not protect intellectual propertyrights to the same extent as federal and state laws in the United States. In-licensing patents covering our product candidates in all countries throughout the world may similarly be prohibitively expensive, ifsuch opportunities are available at all. And in-licensing or filing, prosecuting and defending patents even in only those jurisdictions in which we develop or commercialize our product candidates may beprohibitively expensive or impractical. Competitors may use our and our licensors’ technologies in jurisdictions where we have not obtained patent protection or licensed patents to develop their own products and, further, may export otherwiseinfringing products to territories where we and our licensors have patent protection, but where enforcement is not as strong as that in the United States or Europe. These products may compete with our product candidates, and our or ourlicensors’ patents or other intellectual property rights may not be effective or sufficient to prevent them from competing.

The laws of some jurisdictions do not protect intellectual property rights to the same extent as the laws or regulations inthe United States and Europe, and many companies have encountered significant difficulties in

 

61


Table of Contents

protecting and defending proprietary rights in such jurisdictions. Moreover, the legal systems of certain countries, particularly certain developing countries, do not favor the enforcement ofpatents, trade secrets or other forms of intellectual property, particularly those relating to biotechnology products, which could make it difficult for us to prevent competitors in some jurisdictions from marketing competing products in violationof our proprietary rights generally. Proceedings to enforce our patent rights in foreign jurisdictions, whether or not successful, are likely to result in substantial costs and divert our efforts and attention from other aspects of our business, andadditionally could put at risk our or our licensors’ patents of being invalidated or interpreted narrowly, could increase the risk of our or our licensors’ patent applications not issuing, or could provoke third parties to assert claimsagainst us. We may not prevail in any lawsuits that we initiate, while damages or other remedies may be awarded to the adverse party, which may be commercially significant. If we prevail, damages or other remedies awarded to us, if any, may not becommercially meaningful. Accordingly, our efforts to enforce our intellectual property rights around the world may be inadequate to obtain a significant commercial advantage from the intellectual property that we develop or license. Furthermore,while we intend to protect our intellectual property rights in our expected significant markets, we cannot ensure that we will be able to initiate or maintain similar efforts in all jurisdictions in which we may wish to market our productcandidates. Accordingly, our efforts to protect our intellectual property rights in such countries may be inadequate, which may have an adverse effect on our ability to successfully commercialize our product candidates in all of our expectedsignificant foreign markets. If we or our licensors encounter difficulties in protecting, or are otherwise precluded from effectively protecting, the intellectual property rights important for our business in such jurisdictions, the value of theserights may be diminished and we may face additional competition in those jurisdictions.

In some jurisdictions includingEuropean countries, compulsory licensing laws compel patent owners to grant licenses to third parties. In addition, some countries limit the enforceability of patents against government agencies or government contractors. In these countries, thepatent owner may have limited remedies, which could materially diminish the value of such patent. If we or any of our licensors are forced to grant a license to third parties under patents relevant to our business, or if we or our licensors areprevented from enforcing patent rights against third parties, our competitive position may be substantially impaired in such jurisdictions.

We may rely on trade secret and proprietary know-how which can be difficult totrace and enforce and, if we are unable to protect the confidentiality of our trade secrets, our business and competitive position would be harmed.

In addition to seeking patents for some of our technology and current product candidates or any future product candidates, wemay also rely on trade secrets, including unpatented know-how, technology and other proprietary information, to maintain our competitive position. Elements of our current product candidates or any futureproduct candidates, including processes for their preparation and manufacture, as well as our T-win technology platform, may involve proprietary know-how, information,or technology that is not covered by patents, and thus for these aspects we may consider trade secrets and know-how to be our primary intellectual property. Any disclosure, either intentional or unintentional,by our employees, the employees of third parties with whom we share our facilities or third party consultants and vendors that we engage to perform research, clinical trials or manufacturing activities, or misappropriation by third parties (such asthrough a cybersecurity breach) of our trade secrets or proprietary information could enable competitors to duplicate or surpass our technological achievements, thus eroding our competitive position in our market.

Trade secrets and know-how can be difficult to protect. We require our employees toenter into written employment agreements containing provisions of confidentiality and obligations to assign to us any inventions generated in the course of their employment. We enter into written agreements that include confidentiality andintellectual property obligations to protect each party’s property, potential trade secrets, proprietary know-how, and information. We further seek to protect our potential trade secrets, proprietary know-how, and information in part, by entering into non-disclosure and confidentiality agreements with parties who are given access to them, such as our corporatecollaborators, outside scientific collaborators, CROs, CMOs, consultants, advisors and

other third parties. With our consultants, contractors, and outside scientific collaborators, these agreements typically include invention assignment obligations. Despite these efforts, any ofthese parties may breach the agreements and disclose our proprietary information, including our trade secrets, and we may not be able to obtain adequate remedies for such breaches. Enforcing a claim that a party illegally disclosed ormisappropriated a trade secret is difficult, expensive and time-consuming, and the outcome is unpredictable. In addition, some courts inside and outside the United States are less willing or unwilling to protect trade secrets. If any of our tradesecrets were to be lawfully obtained or independently developed by a competitor or other third party, we would have no right to prevent them from using that technology or information to compete with us. If any of our trade secrets were to bedisclosed to or independently developed by a competitor or other third party, our competitive position would be harmed.

We may become subject to claims challenging the inventorship or ownership of our patents and other intellectualproperty.

We may be subject to claims that former employees, collaborators or other third parties have an interestin our patents or other intellectual property as an inventor or co-inventor. The failure to name the proper inventors on a patent application can result in the patents issuing thereon being unenforceable.Inventorship disputes may arise from conflicting views regarding the contributions of different individuals named as inventors, the effects of foreign laws where foreign nationals are involved in the development of the subject matter of the patent,conflicting obligations of third parties involved in developing our product candidates or as a result of questions regarding co-ownership of potential joint inventions. Litigation may be necessary to resolvethese and other claims challenging inventorship and/or ownership. Alternatively, or additionally, we may enter into agreements to clarify the scope of our rights in such intellectual property. If we fail in defending any such claims, in addition topaying monetary damages, we may lose valuable intellectual property rights, such as exclusive ownership of, or right to use, valuable intellectual property. Such an outcome could have a material adverse effect on our business. Even if we aresuccessful in defending against such claims, litigation could result in substantial costs and be a distraction to management and other employees.

Our licensors may have relied on third-party consultants or collaborators or on funds from third parties, such as the U.S.government, such that our licensors are not the sole and exclusive owners of the patents we may in-license in the future. If other third parties have ownership rights or other rights to our in-licensed patents, they may be able to license such patents to our competitors, and our competitors could market competing products and technology. This could have a material adverse effect on our competitiveposition, business, financial conditions, results of operations, and prospects.

In addition, while it is our policy torequire our employees and contractors who may be involved in the conception or development of intellectual property to execute agreements assigning such intellectual property to us, we may be unsuccessful in executing such an agreement with eachparty who, in fact, conceives or develops intellectual property that we regard as our own. The assignment of intellectual property rights may not be self-executing, or the assignment agreements may be breached, and we may be forced to bring claimsagainst third parties, or defend claims that they may bring against us, to determine the ownership of what we regard as our intellectual property. Such claims could have a material adverse effect on our business, financial condition, results ofoperations, and prospects.

If our trademarks and trade names are not adequately protected, then we may not be ableto build name recognition in our markets of interest and our business may be adversely affected.

Our current orfuture trademarks or trade names may be challenged, infringed, circumvented or declared generic or descriptive or determined to be infringing on other marks. We may not be able to protect our rights to these trademarks and trade names or may beforced to stop using these names, which we need for name recognition by potential partners or customers in our markets of interest. During trademark registration proceedings, we may receive rejections of our applications by the USPTO or in otherforeign jurisdictions.

 

63


Table of Contents

Although we would be given an opportunity to respond to those rejections, we may be unable to overcome such rejections. In addition, in the USPTO and in comparable agencies in many foreignjurisdictions, third parties are given an opportunity to oppose pending trademark applications and to seek to cancel registered trademarks. Opposition or cancellation proceedings may be filed against our trademarks, and our trademarks may notsurvive such proceedings. If we are unable to establish name recognition based on our trademarks and trade names, we may not be able to compete effectively and our business may be adversely affected. We may license our trademarks and tradenames tothird parties, such as distributors. Although these license agreements may provide guidelines for how our trademarks and tradenames may be used, a breach of these agreements or misuse of our trademarks and tradenames by our licensees may jeopardizeour rights in or diminish the goodwill associated with our trademarks and trade names.

Moreover, any name we haveproposed to use with our product candidate in the United States must be approved by the FDA, regardless of whether we have registered it, or applied to register it, as a trademark. Similar requirements exist in Europe. The FDA typically conducts areview of proposed product names, including an evaluation of potential for confusion with other product names. If the FDA (or an equivalent administrative body in a foreign jurisdiction) objects to any of our proposed proprietary product names, itmay be required to expend significant additional resources in an effort to identify a suitable substitute name that would qualify under applicable trademark laws, not infringe the existing rights of third parties and be acceptable to the FDA.Furthermore, in many countries, owning and maintaining a trademark registration may not provide an adequate defense against a subsequent infringement claim asserted by the owner of a senior trademark. At times, competitors or other third parties mayadopt trade names or trademarks similar to ours, thereby impeding our ability to build brand identity and possibly leading to market confusion. In addition, there could be potential trade name or trademark infringement claims brought by owners ofother registered trademarks or trademarks that incorporate variations of our registered or unregistered trademarks or trade names. If we assert trademark infringement claims, a court may determine that the marks we have asserted are invalid orunenforceable, or that the party against whom we have asserted trademark infringement has superior rights to the marks in question. In this case, we could ultimately be forced to cease use of such trademarks.

Risks Related to Common Stock and this Offering

There has been no prior public market for our common stock, the stock price of our common stock may be volatile or maydecline regardless of our operating performance and you may not be able to resell your shares at or above the initial public offering price.

There has been no public market for our common stock prior to this offering. The initial public offering price for our commonstock will be determined through negotiations between the underwriters and us and may vary from the market price of our common stock following this offering. If you purchase shares of our common stock in this offering, you may not be able to resellthose shares at or above the initial public offering price. An active or liquid market in our common stock may not develop upon the completion of this offering or, if it does develop, it may not be sustainable. Further, an inactive market may alsoimpair our ability to raise capital by selling shares of our common stock and may impair our ability to enter into strategic partnerships or acquire companies or products by using our shares of common stock as consideration. The market price of ourcommon stock may fluctuate significantly in response to numerous factors, many of which are beyond our control, including:

 

  

overall performance of the equity markets;

 

  

our operating performance and the performance of other similar companies;

 

  

the published opinions and third-party valuations by banking and market analysts;

 

  

results from our ongoing clinical trials and future clinical trials with our current and future productcandidates or of our competitors;

 

  

adverse results or delays in clinical trials;

 

64


Table of Contents
  

failure to commercialize our product candidates;

 

  

unanticipated serious safety concerns related to immuno-oncology or related to the use of our productcandidates;

 

  

changes in our projected operating results that we provide to the public, our failure to meet theseprojections or changes in recommendations by securities analysts that elect to follow our common stock;

 

  

any delay in our regulatory filings for our product candidates and any adverse development or perceivedadverse development with respect to the applicable regulatory authority’s review of such filings, including without limitation the FDA’s issuance of a “refusal to file” letter or a request for additional information;

 

  

regulatory or legal developments in the United States and other countries;

 

  

the level of expenses related to future product candidates or clinical development programs;

 

  

our failure to achieve product development goals in the timeframe we announce;

 

  

announcements of acquisitions, strategic alliances or significant agreements by us or by our competitors;

 

  

recruitment or departure of key personnel;

 

  

the economy as a whole and market conditions in our industry;

 

  

trading activity by a limited number of stockholders who together beneficially own a majority of ouroutstanding common stock;

 

  

the expiration of market standoff or contractual lock-up agreements;

 

  

the size of our market float;

 

  

political uncertainty and/or instability in the United States;

 

  

the ongoing and future impact of the COVID-19 pandemic and actionstaken to slow its spread; and

 

  

any other factors discussed in this prospectus.

In addition, the stock markets have experienced extreme price and volume fluctuations that have affected and continue toaffect the market prices of equity securities of many immuno-oncology companies. Stock prices of many immuno-oncology companies have fluctuated in a manner unrelated or disproportionate to the operating performance of those companies. The tradingprices for common stock of other biopharmaceutical companies have also been highly volatile as a result of the COVID-19 pandemic. In the past, stockholders have filed securities class action litigationfollowing periods of market volatility. If we were to become involved in securities litigation, it could subject us to substantial costs, divert resources and the attention of management from our business and adversely affect our business.

Our principal stockholders and management own a significant percentage of our stock and will be able to exertsignificant control over matters subject to stockholder approval.

As of June 30, 2021, our executive officers,directors, 5% stockholders and their affiliates beneficially owned approximately            % of our voting stock and, upon closing of this offering, that same group will beneficially ownapproximately            % of our outstanding voting stock, assuming no purchases of any shares of common stock in this offering pursuant to the contemplated directed share program orotherwise. Therefore, even after this offering, these stockholders will have the ability to influence us through their ownership positions. These stockholders may be able to determine all matters requiring stockholder approval. For example, thesestockholders, acting together, may be able to control elections of directors, amendments of our organizational

documents, or approval of any merger, sale of assets, or other major corporate transaction. This may prevent or discourage unsolicited acquisition proposals or offers for our common stock thatyou may believe are in your best interest as one of our stockholders.

Substantial amounts of our outstanding sharesmay be sold into the market when lock-up or market standoff periods end. if there are substantial sales of shares of our common stock, the price of our common stock could decline.

The price of our common stock could decline if there are substantial sales of our common stock, particularly sales by ourdirectors, executive officers and significant stockholders, or if there is a large number of shares of our common stock available for sale and the market perceives that sales will occur. After this offering, we willhave                outstanding shares of our common stock, based on the number of shares outstanding as of June 30, 2021. All of the shares of common stock sold in thisoffering will be available for sale in the public market. Substantially all of our outstanding shares of common stock are currently restricted from resale as a result of market standoff and lock-up agreements,as more fully described in the section of this prospectus titled “Shares Eligible for Future Sale.” These shares will become available to be sold 181 days after the date of this prospectus, in addition to shares issuable pursuant tooutstanding warrants. Shares held by directors, executive officers and other affiliates will be subject to volume limitations under Rule 144 under the Securities Act of 1933, as amended (the Securities Act) and various vesting agreements.

After the completion of this offering, certain of our stockholders will have rights, subject to some conditions, to require usto file registration statements covering their shares or to include their shares in registration statements that we may file for ourselves or our stockholders, subject to market standoff and lockup agreements. We also intend to register shares ofcommon stock that we have issued and may issue under our employee equity incentive plans. Once we register these shares, they will be able to be sold freely in the public market upon issuance, subject to existing market standoff or lock-up agreements. The underwriters of this offering may, in their discretion, permit our stockholders to sell shares prior to the expiration of the restrictive provisions contained in those lock-up agreements.

The market price of the shares of our common stock could decline asa result of the sale of a substantial number of our shares of common stock in the public market or the perception in the market that the holders of a large number of shares intend to sell their shares.

Delaware law and provisions in our amended and restated certificate of incorporation and bylaws could make a merger,tender offer or proxy contest difficult, thereby depressing the trading price of our common stock.

Our amended andrestated certificate of incorporation and bylaws contain provisions that could depress the trading price of our common stock by acting to discourage, delay or prevent a change of control of our company or changes in our management that thestockholders of our company may deem advantageous. These provisions include the following:

 

  

establish a classified board of directors so that not all members of our board of directors are elected at onetime;

 

  

permit the board of directors to establish the number of directors and fill any vacancies and newly-createddirectorships;

 

  

provide that directors may only be removed for cause and only by the affirmative vote of the holders of atleast a majority of the voting power of all then outstanding shares of our capital stock;

 

  

require super-majority voting to amend some provisions in our amended and restated certificate ofincorporation and bylaws;

 

66


Table of Contents
  

authorize the issuance of “blank check” preferred stock that our board of directors could use toimplement a stockholder rights plan;

 

  

prohibit stockholders from calling special meetings of stockholders;

 

  

prohibit stockholder action by written consent, which requires all stockholder actions to be taken at ameeting of our stockholders;

 

  

provide that the board of directors is expressly authorized to make, alter or repeal our bylaws;

 

  

restrict the forum for certain litigation against us to Delaware; and

 

  

establish advance notice requirements for nominations for election to our board of directors or for proposingmatters that can be acted upon by stockholders at annual stockholder meetings.

Any provision of ouramended and restated certificate of incorporation or bylaws or Delaware law that has the effect of delaying or deterring a change in control could limit the opportunity for our stockholders to receive a premium for their shares of our common stock,and could also affect the price that some investors are willing to pay for our common stock.

Our amended andrestated certificate of incorporation designates a state or federal court located within the state of delaware as the exclusive forum for substantially all disputes between us and our stockholders, which could limit our stockholders’ ability tochoose the judicial forum for disputes with us or our directors, officers or employees.

Our amended and restatedcertificate of incorporation provides that, unless we consent in writing to the selection of an alternative forum, to the fullest extent permitted by law, the sole and exclusive forum for (1) any derivative action or proceeding brought on ourbehalf under Delaware law, (2) any action asserting a claim of breach of a fiduciary duty owed by any of our directors, officers or other employees to us or our stockholders, (3) any action arising pursuant to any provision of the DelawareGeneral Corporation Law (DGCL), our amended and restated certificate of incorporation or bylaws, (4) any other action asserting a claim that is governed by the internal affairs doctrine, or (5) any other action asserting an “internalcorporate claim,” as defined in Section 115 of the DGCL, shall be the Court of Chancery of the State of Delaware (or, if the Court of Chancery does not have jurisdiction, the federal district court for the District of Delaware) in allcases subject to the court having jurisdiction over indispensable parties named as defendants. These exclusive-forum provisions do not apply to claims under the Securities Act or the Securities Exchange Act of 1934, as amended (the Exchange Act).

To the extent that any such claims may be based upon federal law claims, Section 27 of the Exchange Act createsexclusive federal jurisdiction over all suits brought to enforce any duty or liability created by the Exchange Act or the rules and regulations thereunder.

Section 22 of the Securities Act creates concurrent jurisdiction for federal and state courts over all suits brought toenforce any duty or liability created by the Securities Act or the rules and regulations thereunder. However, our amended and restated certificate of incorporation contains a federal forum provision which provides that unless the company consents inwriting to the selection of an alternative forum, the federal district courts of the United States of America will be the exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act.

Any person or entity purchasing or otherwise acquiring any interest in any of our securities shall be deemed to have notice ofand consented to this provision. This exclusive forum provision may limit a stockholder’s ability to bring a claim in a judicial forum of its choosing for disputes with us or our directors, officers or other employees, which may discouragelawsuits against us and our directors, officers and other employees. If a court were to find the exclusive forum provision in our amended and restated certificate of incorporation to be inapplicable or unenforceable in an action, we may incuradditional costs associated with resolving the dispute in other jurisdictions, which could harm our results of operations.

If you purchase our common stock in this offering, you will incurimmediate and substantial dilution.

The assumed initial public offering price is substantially higher than the proforma net tangible book value per share of our common stock of $            per share as of June 30, 2021. Investors purchasing common stock in this offering will pay a price per share thatsubstantially exceeds the book value of our tangible assets after subtracting our liabilities. As a result, investors purchasing common stock in this offering will incur immediate dilution of$            per share, based on the assumed initial public offering price of $            per share, which is the midpoint ofthe price range set forth on the cover page of this prospectus. This dilution is due to the substantially lower price paid by our investors who purchased shares prior to this offering as compared to the price offered to the public in this offering.See “Dilution.”

Future sales and issuances of our common stock or rights to purchase common stock,including pursuant to our equity incentive plans, could result in additional dilution of the percentage ownership of our stockholders and could cause our stock price to fall.

Additional capital will be needed in the future to continue our planned operations. To the extent we raise additional capitalby issuing equity securities, our stockholders may experience substantial dilution. We may sell common stock, convertible securities or other equity securities in one or more transactions at prices and in a manner, we determine from time to time. Ifwe sell common stock, convertible securities or other equity securities in more than one transaction, investors may be materially diluted by subsequent sales. These sales may also result in material dilution to our existing stockholders, and newinvestors could gain rights superior to our existing stockholders.

Pursuant to our 2021 Equity Incentive Plan (the 2021Plan), our management is authorized to grant stock options and other equity-based awards to our employees, directors and consultants, which equity-based awards would also cause dilution to our stockholders. The number of shares of our common stockreserved for issuance under our 2021 Plan will automatically increase on January 1 of each calendar year, starting on January 1, 2022 through January 1, 2031, in an amount equal to the lesser of(i)            % of the total number of shares of our common stock outstanding on the last day of the calendar month before the date of each automatic increase; or (ii) a lesser numberof shares determined by our board of directors prior to the applicable January 1st. If our board of directors elects to increase the number of shares available for future grant by the maximum amount each year, our stockholders may experienceadditional dilution, which could cause our stock price to fall.

We do not intend to pay dividends on our commonstock so any returns will be limited to the value of our stock.

We currently anticipate that we will retain futureearnings for the development, operation and expansion of our business and do not anticipate declaring or paying any cash dividends for the foreseeable future. Any return to stockholders will therefore be limited to the appreciation of their stock.

We are an “emerging growth company” and a “smaller reporting company,” and the reduceddisclosure requirements applicable to emerging growth companies and smaller reporting companies may make our common shares less attractive to investors.

We are an “emerging growth company” as defined in the Jumpstart Our Business Startups Act (the JOBS Act), and weintend to take advantage of some of the exemptions from reporting requirements that are applicable to other public companies that are not emerging growth companies, including:

 

  

being permitted to provide only two years of audited financial statements, in addition to any requiredunaudited interim financial statements, with correspondingly reduced “Management’s Discussion and Analysis of Financial Condition and Results of Operations” disclosure;

 

  

not being required to comply with the auditor attestation requirements in the assessment of our internalcontrol over financial reporting;

 

68


Table of Contents
  

not being required to comply with any requirement that may be adopted by the Public Company AccountingOversight Board regarding mandatory audit firm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements;

 

  

reduced disclosure obligations regarding executive compensation; and

 

  

not being required to hold a non-binding advisory vote on executivecompensation or obtain stockholder approval of any golden parachute payments not previously approved.

In addition, as an “emerging growth company” the JOBS Act allows us to delay adoption of new or revised accountingpronouncements applicable to public companies until such pronouncements are made applicable to private companies, unless we later irrevocably elect not to avail ourselves of this exemption. We have elected to use this extended transition periodunder the JOBS Act. As a result, our financial statements may not be comparable to the financial statements of issuers who are required to comply with the effective dates for new or revised accounting standards that are applicable to publiccompanies, which may make comparison of our financials to those of other public companies more difficult. We will remain an emerging growth company until the earlier of (i) the last day of the fiscal year (1) following the fifthanniversary of the completion of this offering, (2) in which we have total annual gross revenue of at least $1.07 billion or (3) in which we are deemed to be a large accelerated filer, which means the market value of our common stockthat is held by non-affiliates exceeds $700 million as of the prior June 30th and (ii) the date on which we have issued more than $1.0 billion innon-convertible debt during the prior three-year period.

We are also a“smaller reporting company meaning that the market value of our stock held by non-affiliates plus the proposed aggregate amount of gross proceeds to us as a result of this offering is less than$700 million and our annual revenue was less than $100 million during the most recently completed fiscal year. Smaller reporting companies may take advantage of certain reduced disclosure obligations, including, among other things,providing only two years of audited financial statements in our Annual Report on Form 10-K, and, similar to emerging growth companies, smaller reporting companies have reduced disclosure obligations regardingexecutive compensation. To the extent we take advantage of such reduced disclosure obligations, it may also make comparison of our financial statements with other public companies difficult or impossible. We will remain a smaller reporting companyuntil the last day of the fiscal year in which (i) the market value of our common shares held by non-affiliates exceeds $250 million as of the end of that year’s second fiscal quarter, or(ii) our annual revenues exceeded $100 million during such completed fiscal year and the market value of our common shares held by non-affiliates exceeds $700 million as of the end of thatyear’s second fiscal quarter.

Investors may find our find our common stock less attractive to the extent we willrely on these exemptions. If some investors find our common stock less attractive as a result, there may be a less active trading market for our common stock and our stock price may be more volatile.

Participation in this offering by our existing stockholders and/or their affiliated entities may reduce the public floatfor our common stock.

To the extent certain of our existing stockholders and their affiliated entities participatein this offering, such purchases would reduce the non-affiliate public float of our shares, meaning the number of shares of our common stock that are not held by officers, directors and controllingstockholders. A reduction in the public float could reduce the number of shares that are available to be traded at any given time, thereby adversely impacting the liquidity of our common stock and depressing the price at which you may be able tosell shares of common stock purchased in this offering.

General Risk Factors

We will incur significantly increased costs as a result of operating as a public company, and our management will berequired to devote substantial time to new compliance initiatives.

As a public company, we will incur significantlegal, accounting and other expenses that we did not incur as a private company. In addition, the Sarbanes-Oxley Act of 2002 (the Sarbanes-Oxley Act), as well as rules subsequently implemented by the SEC, and Nasdaq have imposed various requirementson public companies. In July 2010, the Dodd-Frank Wall Street Reform and Consumer Protection Act (the Dodd-Frank Act) was enacted. There are significant corporate governance and executive compensation related provisions in the Dodd-Frank Act thatrequire the SEC to adopt additional rules and regulations in these areas such as “say on pay” and proxy access. Recent legislation permits smaller “emerging growth companies” to implement many of these requirements over a longerperiod and up to five years from the pricing of this offering. We intend to take advantage of this new legislation but cannot guarantee that we will not be required to implement these requirements sooner than budgeted or planned and thereby incurunexpected expenses. Stockholder activism, the current political environment and the current high level of government intervention and regulatory reform may lead to substantial new regulations and disclosure obligations, which may lead to additionalcompliance costs and impact the manner in which we operate our business in ways we cannot currently anticipate. Our management and other personnel will need to devote a substantial amount of time to these compliance initiatives. Moreover, theserules and regulations will increase our legal and financial compliance costs and will make some activities more time-consuming and costlier. For example, we expect these rules and regulations to make it more difficult and more expensive for us toobtain director and officer liability insurance and we may be required to incur substantial costs to maintain our current levels of such coverage.

Failure to build our finance infrastructure and improve our accounting systems and controls could impair our ability tocomply with the financial reporting and internal controls requirements for publicly traded companies.

As a publiccompany, we will operate in an increasingly demanding regulatory environment, which requires us to comply with the Sarbanes-Oxley Act, the regulations of Nasdaq, the rules and regulations of the SEC, expanded disclosure requirements, acceleratedreporting requirements and more complex accounting rules. Company responsibilities required by the Sarbanes-Oxley Act include establishing corporate oversight and adequate internal control over financial reporting and disclosure controls andprocedures. Effective internal controls are necessary for us to produce reliable financial reports and are important to help prevent financial fraud. Commencing with our fiscal year ending the year after this offering is completed, we must performsystem and process evaluation and testing of our internal controls over financial reporting to allow management to report on the effectiveness of our internal controls over financial reporting in our Form 10-Kfiling for that year, as required by Section 404 of the Sarbanes-Oxley Act. Prior to this offering, we have never been required to test our internal controls within a specified period and, as a result, we may experience difficulty in meetingthese reporting requirements in a timely manner. Further, in connection with the audit of our financial statements for the years ended December 31, 2020 and 2019, we and our independent registered public accounting firm identified a materialweakness in our internal control over financial reporting.

We anticipate that the process of remediating the beforementioned material weakness in our internal control over financial reporting and building our accounting and financial functions and infrastructure will require significant additional professional fees, internal costs and management efforts. Weexpect that we will need to implement a new internal system to combine and streamline the management of our financial, accounting, human resources and other functions. However, such a system would likely require us to complete many processes andprocedures for the effective use of the system or to run our business using the system, which may result in substantial costs. Any disruptions or difficulties in implementing or using such a system could adversely affect our controls and harm ourbusiness. Moreover, such disruption or difficulties could result in unanticipated costs and diversion of management attention. In addition, we may discover weaknesses in our system of internal

Table of Contents

financial and accounting controls and procedures that could result in a material misstatement of our financial statements. Our internal control over financial reporting will not prevent or detectall errors and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system’s objectives will be met. Because of the inherent limitations in all controlsystems, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud will be detected.

If we are not able to comply with the requirements of Section 404 of the Sarbanes-Oxley Act in a timely manner, or if weare unable to maintain proper and effective internal controls, we may not be able to produce timely and accurate financial statements. If we cannot provide reliable financial reports or prevent fraud, our business and results of operations could beharmed, investors could lose confidence in our reported financial information and we could be subject to sanctions or investigations by Nasdaq, the SEC or other regulatory authorities.

Our disclosure controls and procedures may not prevent or detect all errors or acts of fraud.

Upon the completion of this offering, we will become subject to the periodic reporting requirements of the Exchange Act. Wedesigned our disclosure controls and procedures to reasonably assure that information we must disclose in reports we file or submit under the Exchange Act is accumulated and communicated to management, and recorded, processed, summarized andreported within the time periods specified in the rules and forms of the SEC. We believe that any disclosure controls and procedures or internal controls and procedures, no matter how well-conceived and operated, can provide only reasonable, notabsolute, assurance that the objectives of the control system are met.

These inherent limitations include the realitiesthat judgments in decision-making can be faulty, and that breakdowns can occur because of simple error or mistake. For example, our directors or executive officers could inadvertently fail to disclose a new relationship or arrangement causing us tofail to make any related party transaction disclosures. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people or by an unauthorized override of the controls. Accordingly, because of theinherent limitations in our control system, misstatements due to error or fraud may occur and not be detected.

Future changes in financial accounting standards or practices may cause adverse and unexpected revenue fluctuations andadversely affect our reported results of operations.

Future changes in financial accounting standards may causeadverse, unexpected revenue fluctuations and affect our reported financial position or results of operations. Financial accounting standards in the United States are constantly under review and new pronouncements and varying interpretations ofpronouncements have occurred with frequency in the past and are expected to occur again in the future. As a result, we may be required to make changes in our accounting policies. Those changes could affect our financial condition and results ofoperations or the way in which such financial condition and results of operations are reported. We intend to invest resources to comply with evolving standards, and this investment may result in increased general and administrative expenses and adiversion of management time and attention from business activities to compliance activities. See the section titled “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Recent AccountingPronouncements.”

Changes in tax laws or regulations that are applied adversely to us or our customers may havea material adverse effect on our business, cash flow, financial condition or results of operations.

New income,sales, use, or other tax laws, statutes, rules, regulations or ordinances could be enacted at any time, which could adversely affect our business operations and financial performance. Further, existing tax laws, statutes, rules, regulations, orordinances could be interpreted, changed, modified, or applied adversely to us. For example, the TCJA enacted many significant changes to the U.S. tax laws. Future guidance from the IRS and

Table of Contents

other tax authorities with respect to the TCJA may affect us, and certain aspects of the TCJA could be repealed or modified in future legislation. For example, the Coronavirus Aid, Relief, andEconomic Security Act modified certain provisions of the TCJA. In addition, it is uncertain if and to what extent various states will conform to the TCJA or any newly enacted federal tax legislation. Changes in corporate tax rates, the realizationof net deferred tax assets relating to our operations, the taxation of foreign earnings, and the deductibility of expenses under the TCJA or future reform legislation could have a material impact on the value of our deferred tax assets, could resultin significant one-time charges, and could increase our future U.S. tax expense.

In addition, the recent presidential and congressional elections in the United States could also result in significant changesin, and uncertainty with respect to, tax legislation, regulation and government policy directly affecting us and our business. For example, the United States government may enact significant changes to the taxation of business entities including,among others, a permanent increase in the corporate income tax rate, an increase in the tax rate applicable to the global intangible low-taxed income and elimination of certain exemptions, and the impositionof minimum taxes or surtaxes on certain types of income. The likelihood of these changes being enacted or implemented is unclear.

Unstable market and economic conditions may have serious adverse consequences on our business, financial condition andstock price.

As a result of the COVID-19 pandemic and actions taken toslow its spread, the global credit and financial markets have recently experienced extreme volatility and disruptions, including severely diminished liquidity and credit availability, declines in consumer confidence, declines in economic growth,increases in unemployment rates and uncertainty about economic stability. There can be no assurance that further deterioration in credit and financial markets and confidence in economic conditions will not occur. Our general business strategy may beadversely affected by any such economic downturn, volatile business environment or continued unpredictable and unstable market conditions. If the current equity and credit markets deteriorate, it may make any necessary debt or equity financing moredifficult, more costly and more dilutive. Failure to secure any necessary financing in a timely manner and on favorable terms could have a material adverse effect on our growth strategy, financial performance and stock price and could require us todelay or abandon clinical development plans. In addition, there is a risk that one or more of our current service providers, manufacturers and other partners may not survive an economic downturn, which could directly affect our ability to attain ouroperating goals on schedule and on budget.

We will have broad discretion in the use of the net proceeds of thisoffering and may not use them effectively or in ways that increase the value of our share price.

We cannot specifywith any certainty the particular uses of the net proceeds that we will receive from this offering. We will have broad discretion in the application of the net proceeds, including working capital and other general corporate purposes, and you andother stockholders may disagree with how we spend or invest these proceeds. The failure by our management to apply these funds effectively could adversely affect our business and financial condition. Pending their use, we may invest the net proceedsfrom our initial public offering in a manner that does not produce income or that loses value. These investments may not yield a favorable return to our investors.

Our internal information technology systems, or those of our third-party CROs or other contractors or consultants, mayfail or suffer security breaches, loss or leakage of data, and other disruptions, which could result in a material disruption of our product candidates’ development programs, compromise sensitive information related to our business or preventus from accessing critical information, potentially exposing us to liability or otherwise adversely affecting our business.

We are increasingly dependent upon information technology systems, infrastructure and data to operate our business. In theordinary course of business, we collect, store and transmit confidential information (including

 

72


Table of Contents

but not limited to intellectual property, proprietary business information and personal information). It is critical that we do so in a secure manner to maintain the confidentiality and integrityof such confidential information. We have also outsourced elements of our operations to third parties, and as a result we manage a number of third-party contractors who have access to our confidential information.

Despite the implementation of security measures, given their size and complexity and the increasing amounts of confidentialinformation that they maintain, our internal information technology systems and those of our third-party CROs and other contractors and consultants are potentially vulnerable to breakdown or other damage or interruption from service interruptions,system malfunction, natural disasters, terrorism, war and telecommunication and electrical failures, as well as security breaches from inadvertent or intentional actions by our employees, contractors, consultants, business partners, and/or otherthird parties, or from cyber-attacks by malicious third parties (including the deployment of harmful malware, ransomware, extortion, account takeover attacks, degradation of service attacks, denial-of-service attacks, “phishing,” or social engineering and other means to affect service reliability and threaten the confidentiality, integrity and availability of information), which maycompromise our system infrastructure or lead to data leakage. We have technology security initiatives and disaster recovery plans in place to mitigate our risk to these vulnerabilities, but these measures may not be adequately designed orimplemented to ensure that our operations are not disrupted or that data security breaches do not occur. To the extent that any disruption or security breach were to result in a loss of, or damage to, our data or applications, or inappropriatedisclosure of confidential or proprietary information, we could incur liability and reputational damage.

Hackers and datathieves are increasingly sophisticated and operate large-scale and complex automated attacks which may remain undetected until after they occur. We cannot assure you that our data protection efforts and our investment in information technology willprevent significant breakdowns, data leakages, breaches in our systems or other cyber incidents that could have a material adverse effect upon our reputation, business, operations or financial condition. For example, if such an event were to occurand cause interruptions in our operations, it could result in a material disruption of our programs and the development of our product candidates could be delayed. In addition, the loss of clinical trial data for our product candidates could resultin delays in our marketing approval efforts and significantly increase our costs to recover or reproduce the data. Furthermore, significant disruptions of our internal information technology systems or security breaches could result in the loss,misappropriation, and/or unauthorized access, use, or disclosure of, or the prevention of access to, confidential information (including trade secrets or other intellectual property, proprietary business information, and personal information), whichcould result in financial, legal, business, and reputational harm to us. Like all businesses we may be increasingly subject to ransomware or other malware that could significantly disrupt our business operations, or disable or interfere withnecessary access to essential data or processes. Numerous recent attacks of this nature have also involved exfiltration and disclosure of sensitive or confidential personal or proprietary information, or intellectual property, when victim companieshave not paid the cyber criminals substantial ransom payments. For example, any such event that leads to unauthorized access, use, disclosure, unavailability, or compromised integrity of personal or other sensitive or essential information,including personal information regarding our clinical trial subjects or employees, could harm our reputation directly, compel us to comply with federal and/or state breach notification laws and foreign law equivalents, subject us to mandatorycorrective action, increase the costs we incur to protect against such information security breaches, such as increased investment in technology, render key personnel unable to perform duties or communicate throughout the organization and otherwisesubject us to fines and other liability under laws and regulations that protect the privacy and security of personal information, which could result in significant legal and financial exposure and reputational damages that could potentially have anadverse effect on our business.

The costs of mitigating cybersecurity risks are significant and are likely to increase inthe future. These costs include, but are not limited to, retaining the services of cybersecurity providers; compliance costs arising out of existing and future cybersecurity, data protection and privacy laws and regulations; and costs related tomaintaining redundant networks, data backups and other damage-mitigation measures. We also cannot be certain that our existing insurance coverage will continue to be available on acceptable terms or in amounts sufficient to

 

73


Table of Contents

cover the potentially significant losses that may result from a security incident or breach or that the insurer will not deny coverage of any future claim.

Our operations as a global company subject us to various risks, and our failure to manage these risks could adverselyaffect our business, results of operations, cash flows, financial condition and/or prospects.

We face significantoperational risks as a result of doing business globally, such as:

 

  

fluctuations in currency exchange rates (in particular, U.S. dollars, Euros and Danish kroner);

 

  

potentially adverse tax consequences, including the complexities of foreign value-added tax systems, taxinefficiencies related to our corporate structure, and potential restrictions on the repatriation of earnings;

 

  

export restrictions, trade regulations and foreign tax laws;

 

  

customs clearance and shipping delays;

 

  

the burdens of complying with a wide variety of foreign laws and different legal standards; and

 

  

increased financial accounting and reporting burdens and complexities.

If one or more of these risks are realized, it could have a material adverse effect on our business, results of operations,cash flows, financial condition and/or prospects.

We or the third parties upon whom we depend may be adverselyaffected by earthquakes, fires or other natural disasters and our business continuity and disaster recovery plans may not adequately protect us from a serious disaster.

If earthquakes, fires, other natural disasters, terrorism and similar unforeseen events beyond our control prevent us fromusing all or a significant portion of our headquarters or other facilities, it may be difficult or, in certain cases, impossible for us to continue our business for a substantial period of time. We do not have a disaster recovery or businesscontinuity plan in place and may incur substantial expenses as a result of the absence or limited nature of our internal or third-party service provider disaster recovery and business continuity plans, which, particularly when taken together withour lack of earthquake insurance, could have a material adverse effect on our business. Furthermore, integral parties in our supply chain are operating from single sites, increasing their vulnerability to natural disasters or other sudden,unforeseen and severe adverse events. If such an event were to affect our supply chain, it could have a material adverse effect on our ability to conduct our clinical trials, our development plans and business.

We are subject to certain U.S. and foreign anti-corruption, anti-money laundering, export control, sanctions, and othertrade laws and regulations. We can face serious consequences for violations.

U.S. and foreign anti-corruption,anti-money laundering, export control, sanctions, and other trade laws and regulations (collectively, Trade Laws) prohibit, among other things, companies and their employees, agents, CROs, legal counsel, accountants, consultants, contractors, andother partners from authorizing, promising, offering, providing, soliciting, or receiving directly or indirectly, corrupt or improper payments or anything else of value to or from recipients in the public or private sector. Violations of Trade Lawscan result in substantial criminal fines and civil penalties, imprisonment, the loss of trade privileges, debarment, tax reassessments, breach of contract and fraud litigation, reputational harm, and other consequences. We have direct or indirectinteractions with officials and employees of government agencies or government-affiliated hospitals, universities, and other organizations. We also expect to continue our non-U.S. activities, which mayincrease over time. We expect to rely on third parties for research, preclinical studies, and clinical trials and/or to obtain necessary permits, licenses, patent registrations, and other marketing approvals. We can be held liable for the corrupt orother illegal activities of our personnel, agents, or partners, even if we do not explicitly authorize or have prior knowledge of such activities.

Table of Contents

If we fail to comply with environmental, health and safety laws andregulations, we could become subject to fines or penalties or incur costs that could have a material adverse effect on the success of our business.

We, and the third parties with whom we share our facilities, are subject to numerous environmental, health and safety laws andregulations, including those governing laboratory procedures and the handling, use, storage, treatment and disposal of hazardous materials and wastes. Each of our operations involve the use of hazardous and flammable materials, including chemicalsand biological and radioactive materials. Each of our operations also produce hazardous waste products. We generally contract with third parties for the disposal of these materials and wastes. We cannot eliminate the risk of contamination or injuryfrom these materials. We could be held liable for any resulting damages in the event of contamination or injury resulting from the use of hazardous materials by us or the third parties with whom we share our facilities, and any liability couldexceed our resources. We also could incur significant costs associated with civil or criminal fines and penalties.

Although we maintain workers’ compensation insurance to cover us for costs and expenses we may incur due to injuries toour employees resulting from the use of hazardous materials, this insurance may not provide adequate coverage against potential liabilities. We do not maintain insurance for environmental liability or toxic tort claims that may be asserted againstus in connection with our storage or disposal of biological, hazardous or radioactive materials.

In addition, we mayincur substantial costs in order to comply with current or future environmental, health and safety laws and regulations. These current or future laws and regulations may impair our research and development. Failure to comply with these laws andregulations also may result in substantial fines, penalties or other sanctions.

We could be subject to securitiesclass action litigation.

In the past, securities class action litigation has often been brought against a companyfollowing a decline in the market price of its securities. This risk is especially relevant for us because pharmaceutical companies have experienced significant stock price volatility in recent years. If we face such litigation, it could result insubstantial costs and a diversion of management’s attention and resources, which could harm our business.

Ifsecurities or industry analysts do not publish research or publish inaccurate or unfavorable research about our business, our stock price and trading volume could decline.

The trading market for our common stock will depend in part on the research and reports that securities or industry analystspublish about us or our business. Securities and industry analysts do not currently, and may never, publish research on our company. If no or only very few securities analysts commence coverage of us, or if industry analysts cease coverage of us,the trading price for our common stock would be negatively affected. If one or more of the analysts who cover us downgrade our common stock or publish inaccurate or unfavorable research about our business, our common stock price would likelydecline. If one or more of these analysts cease coverage of us or fail to publish reports on us regularly, demand for our common stock could decrease, which might cause our common stock price and trading volume to decline.

USE OF PROCEEDS

We estimate that the net proceeds to use from this offering will be approximately$             , based on an assumed initial public offering price of $             per share, which is the midpoint of the pricerange set forth on the cover page of this prospectus, after deducting estimated underwriting discounts and commissions and estimated offering expenses payable by us. If the underwriters fully exercise their option to purchase additional common stockin this offering, we estimate that our net proceeds will be approximately $            , based on an assumed initial public offering price of$             per share, which is the midpoint of the price range set forth on the cover page of this prospectus, after deducting estimated underwriting discounts and commissions andestimated offering expenses payable by us.

Each $1.00 increase (decrease) in the assumed initial public offering price of$             per share, which is the midpoint of the price range set forth on the cover page of this prospectus, would increase (decrease) the net proceeds from this offering by$            , assuming that the number of shares offered by us, as set forth on the cover page of this prospectus, remains the same and after deducting estimated underwriting discounts andcommissions and estimated offering expenses payable by us. Similarly, each 1 million share increase (decrease) in the number of shares offered by us would increase (decrease) the net proceeds from this offering by$            , assuming no change in the assumed initial public offering price per share and after deducting estimated underwriting discounts and commissions and estimated offering expensespayable by us. We do not expect that a change in the initial public offering price or the number of shares by these amounts would have a material effect on our uses of the proceeds from this offering, although it may accelerate the time when we needto seek additional capital.

We intend to use the net proceeds of this offering as follows:

 

  

approximately $             million to fund thecontinued development of IO102-IO103 in the planned Phase 3 trial in first line advanced melanoma;

 

  

approximately $             million to fundongoing development of IO102-IO103 in the planned Phase 2 “basket” trials;

 

  

approximately $             million to fundplanned development of IO112, including in a planned Phase 1/2 trial in combination with IO102 and IO103; and

 

  

the remainder for research and development and general and administrative headcount costs, cross-programresearch and development activities, and other general corporate purposes and working capital.

We mayalso use a portion of the net proceeds from this offering to in-license, acquire, or invest in complementary businesses, technologies, products or assets. However, we have no current plans, commitments orobligations to do so.

Based on our current plans, we believe that the net proceeds from this offering, together with ourexisting cash and cash equivalents, will be sufficient to fund our operations through             . The net proceeds of this offering, together with our existing cash and cash equivalents,will not be sufficient to complete development of IO102-IO103, IO112 or any other product candidate, and we will need to raise substantial additional capital to complete the development and commercializationof any product candidate.

Pending our use of the net proceeds from this offering, we intend to investor our net proceedsfrom this offering primarily in investment-grade, interest-bearing instruments.

The expected use of net proceeds fromthis offering represents our intentions based upon our current plans and business conditions. We cannot predict with certainty all of the particular uses for the net proceeds from this offering or that amounts that we will actually spend on the usesset forth above. The amount and timing of our actual expenditures will depend on numerous factors, including the results of our research and development efforts, the timing and outcome of any ongoing or future clinical studies, and the timing andoutcome of regulatory submissions. Accordingly, our management will have significant flexibility in applying the net proceeds of this offering. The timing and amount of our actual expenditures will be based on many factors, including cash flows fromoperations and the anticipated growth of our business.

CORPORATE REORGANIZATION

IO ApS

Currently, thecapital structure of IO ApS consists of three classes of equity interests: class A ordinary shares, class B preference shares and class C preference shares.

Corporate Reorganization

Prior to the completion of this offering, we intend to engage in a series of transactions, which we refer to collectively asthe Corporate Reorganization. As a result of the Corporate Reorganization, IO ApS will become a wholly-owned subsidiary of IO Biotech, Inc. and our consolidated financial statements will be reported from IO Biotech, Inc. IO Biotech is recentlyformed holding company with nominal assets and no liabilities, contingencies, or commitments, which will not have conducted any operations prior to this offering other than acquiring the entire issued and outstanding stock of IO Biotech ApS. We, IOApS, and the holders of all of the issued and outstanding equity interests of IO ApS have entered into a Share Contribution and Exchange Agreement, dated as of             , 2021, pursuantto which the Corporate Reorganization will be effected.

In May 2021, we formed IO Biotech, Inc. as a stand-alone entity.In the period from May 2021 to October 14, 2021, the company has been dormant. We believe the remaining steps to the Corporate Reorganization will include:

 

  

Each holder of IO ApS equity interests shall contribute, transfer, grant, assign and deliver to us all of itsright, title and interest in and to all IO ApS equity interests owned by such holder;

 

  

In exchange for each IO ApS class A share contributed by a holder, we will issue to such holder one share ofour Class A stock;

 

  

In exchange for each IO ApS class B preference share contributed by a holder, we will issue to such holder oneshare of our Series B preferred stock;

 

  

In exchange for each IO ApS class C preference share contributed by a holder, we will issue to such holder oneshare of our Series C preferred stock;

 

  

In exchange for each warrant to purchase an IO ApS class A share contributed by a holder, we will issue tosuch holder a warrant to purchase a share of our Class A stock; and

 

  

Any other steps necessary to affect our consolidated financial statements being reported from IO Biotech, Inc.going forward after the Corporate Reorganization.

Upon the closing of the offering, the issued andoutstanding shares of our Class A stock will then be converted into an aggregate of              shares of our common stock, and the issued and outstanding shares of our Series B preferredstock and Series C preferred stock will then be converted into an aggregate of              shares of our common stock, after which holders of all of the issued and outstanding equityinterest of IO ApS will have received 100% of our outstanding common stock upon the closing of the offering.

If you invest in our common stock in this offering, your ownership interest will be diluted to the extent of the differencebetween the initial public offering price per share of our common stock and the pro forma as adjusted net tangible book value (deficit) per share of our common stock immediately after this offering.

Our historical net tangible book value (deficit) per share as of June 30, 2021 is determined by dividing our totaltangible assets less our total liabilities and convertible preference shares, which are not included within stockholders’ equity (deficit), by the number of shares of common stock outstanding as of such date. Our historical net tangible bookvalue (deficit) was ($81.3 million), or ($1,626.18) per share as of June 30, 2021.

Our pro forma net tangible book value(deficit) as of June 30, 2021 was $             million, or $             per share. Our pro forma net tangible book value(deficit) per share represents the amount of our total tangible assets reduced by the amount of our total liabilities and divided by the total number of shares of our common stock outstanding as of June 30, 2021, assuming (i) the CorporateReorganization (ii) the automatic conversion of all outstanding shares of our Class A stock into an aggregate of              shares of our common stock, which conversion will occur uponthe closing of this offering, (iii) the automatic conversion of all outstanding convertible preference shares into an aggregate of              shares of common stock, which conversionwill occur upon the closing of this offering, and (iv) the closing of the sale and issuance of our second tranche Class C preference shares.

Our pro forma as adjusted net tangible book value (deficit) represents our pro forma net tangible book (deficit) value, plusthe effect of the sale of shares of common stock in this offering at an assumed initial public offering price of $             per share, the midpoint of the price range set forth on thecover page of this prospectus, after deducting estimated underwriting discounts and commissions and estimated offering expenses payable by us. Net tangible book value dilution per share to new investors represents the difference between the amountper share paid by purchasers of shares of common stock in this offering and the pro forma as adjusted net tangible book value per share of common stock immediately after completion of this offering. After giving effect to our sale of shares ofcommon stock in this offering at an assumed initial public offering price of $             per share, the midpoint of the price range set forth on the cover page of this prospectus, andafter deducting estimated underwriting discounts and commissions and estimated offering expenses payable by us, our pro forma as adjusted net tangible book value as of June 30, 2021 would have been$             million, or $             per share. This represents an immediate increase in net tangible book value of$             per share to existing stockholders and an immediate dilution in net tangible book value of $             per shareto purchasers of common stock in this offering, as illustrated in the following table:

Each $1.00 increase or decrease in the assumed public offering price of$             per share, which is the midpoint of the price range set forth on the cover page of this prospectus, would increase or decrease, as applicable, our pro forma as adjusted nettangible book value by $             million, or $             per share, and dilution per share to investors in this offering by$             per share, assuming that the number of shares offered by us, as set forth on the cover of this prospectus, remains the same, and after deducting estimated underwritingdiscounts and commissions, and estimated offering expenses payable by us. We may also increase or decrease

the number of shares we are offering. Each increase or decrease of 1.0 million shares in the number of shares we are offering would increase or decrease, as applicable, our pro forma asadjusted net tangible book value by $             million, or $             per share and would increase or decrease, asapplicable, dilution per share to investors in this offering by $             per share, assuming the assumed initial public offering price per share remains the same and after deductingestimated underwriting discounts and commissions, and estimated offering expenses payable by us.

If theunderwriters’ option to purchase additional shares from us is exercised in full, the pro forma as adjusted net tangible book value per share after this offering would be $            per share and would be decreased or increased, as applicable, accordingly by $             per share; the increase in pro forma as adjusted net tangible book value per share to existingstockholders would be $             per share; and the dilution to new investors purchasing shares in this offering would be$             per share.

The following table shows, as ofJune 30, 2021, on a pro forma as adjusted basis described above (but before deducting estimated underwriting discounts and commissions and estimated offering expenses payable by us), the differences between the existing stockholders and thepurchasers of shares in this offering with respect to the number of shares purchased from us, the total consideration paid, which includes net proceeds received from the issuance of common and convertible preference shares, cash received from theexercise of warrants, and the value of any stock issued for services and the average price paid per share (in thousands, except per share amounts and percentages):

The table above assumes no exercise of the underwriters’ option to purchase additionalshares in this offering. If the underwriters’ option to purchase additional shares is exercised in full, the number of shares of our common stock held by existing stockholders would be reduced to     % of the total number ofshares of our common stock outstanding after this offering, and the number of shares of common stock held by new investors participating in the offering would be increased to     % of the total number of shares of our commonstock outstanding after this offering.

The foregoing tables and calculations (other than the historical net tangible bookvalue (deficit) calculations) are based on              shares of common stock (including our Class A stock and convertible preferred stock on an as converted basis) outstanding as of            , and excludes:

 

  

             shares of common stock issuable uponexercise of outstanding warrants issued as of June 30, 2021, at a weighted-average exercise price of $             per share; and

 

  

             shares of common stock reserved forissuance pursuant to future awards under the 2021 Plan or the ESPP, plus any future increases in the number of shares of common stock reserved for issuance under the 2021 Plan or the ESPP pursuant to provisions thereof that automatically increasethe share reserve under the plan each year.

To the extent that any outstanding warrants are exercised,new options are issued under our stock-based compensation plans or we issue additional shares of common stock or convertible debt in the future, there will be further dilution to investors participating in this offering.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION

AND RESULTS OF OPERATIONS

You should read the following discussion and analysis of our financial condition and results of operations together withour financial statements and related notes appearing at the end of this prospectus. Some of the information contained in this discussion and analysis or set forth at the end of this prospectus, including information with respect to our plans andstrategy for our business and related financing, includes forward-looking statements that involve risks and uncertainties. As a result of many factors, including those factors set forth in the section entitled “Risk Factors,” our actualresults could differ materially from the results described in or implied by the forward-looking statements contained in the following discussion and analysis. You should carefully read the section entitled “Risk Factors” to gain anunderstanding of the important factors that could cause actual results to differ materially from our forward- looking statements. Please also see the section entitled “Cautionary Note Regarding Forward-Looking Statements and IndustryData.”

Overview

We are a clinical-stage biopharmaceutical company developing novel, immune-modulating cancer therapies based on our T-win technology platform. Our product candidates are designed to induce the immune system to simultaneously target and disrupt multiple pathways that regulate tumor-induced immunosuppression. We believe thisrepresents a paradigm shift in the management of cancer and that our product candidates have the potential to become cornerstones of the treatment regimens of multiple solid tumors. Our lead product candidate, IO102-IO103, is designed to target theimmunosuppressive mechanisms mediated by key immunosuppressive proteins such as IDO and PD-L1. In a Phase 1/2 clinical trial of 30 patients with metastatic melanoma, IO102-IO103, in combination withnivolumab, demonstrated an ability to induce meaningful tumor regression and establish durable antitumor response while achieving a manageable tolerability profile for patients. In this trial, we observed a confirmed ORR of 73% and a CR rate of 47%.Based on the results from this trial, IO102-IO103, in combination with pembrolizumab was granted BTD by the FDA for treatment of unresectable/metastatic melanoma and we are currently planning a potentially registrational Phase 3 trial forIO102-IO103.

Our ability to generate revenue from product sales sufficient to achieve profitability will depend heavilyon the successful development and eventual commercialization of one or more of our product candidates. Our operations to date have been financed primarily by aggregate net proceeds of $101.2 million from the issuance of convertible preferenceshares, convertible notes and ordinary shares, including the issuance of 505,520 Class C convertible preference shares for gross proceeds of $61.5 million in January 2021 and the issuance of 35,825 Class C convertible preferenceshares for net proceeds of $4.2 million in March 2021. As a result of entering into a collaboration agreement with Merck in September 2021, the number of class C preference shares issued in March 2021 was adjusted downward to 32,568 class Cpreference shares. Since inception, we have had significant operating losses. Our net loss was $45.5 for the six months ended June 30, 2021 and $12.0 million and $10.7 million for the years ended December 31, 2020 and 2019,respectively. As of June 30, 2021, we had an accumulated deficit of $83.9 million and $54.8 million in cash and cash equivalents.

Cash used to fund operating expenses is impacted by the timing of when we pay these expenses, as reflected in the change inour accounts payable and accrued expenses. We expect to continue to incur net losses for the foreseeable future, and we expect our research and development expenses, general and administrative expenses, and capital expenditures will continue toincrease. In particular, we expect our expenses to increase as we continue our development of, and seek regulatory approvals for, our product candidates, as well as hire additional personnel, pay fees to outside consultants, lawyers and accountants,and incur other increased costs associated with being a public company. In addition, if and when we seek and obtain regulatory approval to commercialize any product candidate, we will also incur increased expenses in connection withcommercialization and marketing of any such product. Our net losses may fluctuate significantly from quarter-to-quarter and year-to-year, depending on the timing of our clinical trials and our expenditures on other research and development activities.

Based upon our current operating plan, we believe that the net proceeds from this offering together with our existing cash andcash equivalents of $54.8 million as of June 30, 2021, and the $84.1 million of gross proceeds

 

85


Table of Contents

from the sale and issuance of our second tranche Class C preference shares in October 2021, will be sufficient to continue funding our development activitiesthrough                . We have based this estimate on assumptions that may prove to be wrong, and we could exhaust our available capital resources sooner than weexpect. To finance our operations beyond that point we will need to raise additional capital, which cannot be assured.

Todate, we have not had any products approved for sale and, therefore, have not generated any product revenue. We do not expect to generate any revenues from product sales unless and until we successfully complete development and obtain regulatoryapproval for one or more of our product candidates. If we obtain regulatory approval for any of our product candidates, we expect to incur significant commercialization expenses related to product sales, marketing, manufacturing and distribution. Asa result, until such time, if ever, that we can generate substantial product revenue, we expect to finance our cash needs through equity offerings, debt financings or other capital sources, including collaborations, licenses or similar arrangements.However, we may be unable to raise additional funds or enter into such other arrangements when needed or on favorable terms, if at all. Any failure to raise capital as and when needed could have a negative impact on our financial condition and onour ability to pursue our business plans and strategies, including our research and development activities. If we are unable to raise capital, we will need to delay, reduce or terminate planned activities to reduce costs.

In March 2020, the World Health Organization declared the COVID-19 outbreak apandemic. In order to mitigate the spread of COVID-19, governments have imposed unprecedented restrictions on business operations, travel and gatherings, resulting in a global economic downturn and otheradverse economic and societal impacts. The COVID-19 pandemic has also overwhelmed or otherwise led to changes in the operations of many healthcare facilities, including clinical trial sites. While we areconsidered an essential business under applicable regulations and continue to operate, the impacts of the COVID-19 pandemic initially placed significant strain on our clinical trial sites, have raised concernsaround monitoring patient safety, and caused enrollment to slow in the Phase 2 portion of the ongoing Phase 2 clinical trial of IO102. We are continuing to work closely with our clinical partners and have taken steps as necessary to adjust ourprotocols and timelines due to the impact of the COVID-19 pandemic. The COVID-19 pandemic and its impacts continue to evolve. We cannot predict the scope and severity ofany further disruptions as a result of COVID-19 or their impacts on us, but business disruptions for us or any of the third parties with whom we engage, including the collaborators, contract organizations,third-party manufacturers, suppliers, clinical trial sites, regulators and other third parties with whom we conduct business could materially and negatively impact our ability to conduct our business in the manner and on the timelines presentlyplanned. The extent to which the COVID-19 pandemic may continue to impact our business and financial performance will depend on future developments, which are highly uncertain and cannot be predicted withconfidence, including the scope and duration of the pandemic, the extent and effectiveness of government restrictions and other actions, including relief measures, implemented to address the impact of the pandemic, and resulting economic impacts. Weare unable to determine the extent of the impact of the pandemic on our clinical trials, operations and financial condition going forward. These developments are highly uncertain and unpredictable, and may materially adversely affect our financialposition and results of operations.

Components of Operating Results

Operating Expenses

Our operating expenses since inception have consisted primarily of research and development expenses and general andadministrative costs.

Research and Development

Our research and development expenses consist primarily of costs incurred for the development of our product candidates and ourdrug discovery efforts, which include:

 

  

personnel costs, which include salaries, benefits and equity-based compensation expense;

 

86


Table of Contents
  

expenses incurred under agreements with outside consultants and advisors, including their fees and relatedtravel expenses;

 

  

expenses incurred under agreements with third parties, including contract research organizations (CROs) thatconduct research, preclinical activities and clinical trials on our behalf as well as contract manufacturing organizations, (CMOs) that manufacture our product candidates for use in our preclinical and clinical trials and perform chemistry,manufacturing and control activities (CMC);

 

  

laboratory and vendor expenses related to the execution of preclinical studies and planned and ongoingclinical trials;

 

  

expenses related to research conducted by institutions, universities and hospitals as part of collaborations;

 

  

filing and maintenance of patents and intellectual property rights, including payment to third parties forassignment of patent rights and licensing fees and milestone payments incurred under product license agreements where no alternative future use exists;

 

  

laboratory supplies and equipment used for internal research and development activities; and

 

  

facility-related expenses, which include direct depreciation costs and allocated expenses for rent andmaintenance of facilities and other operating costs.

We expense all research and development costs inthe periods in which they are incurred. Costs for certain research and development activities are recognized based on an evaluation of the progress to completion of specific tasks using information and data provided to us by our vendors andthird-party service providers.

From time to time, we obtain grants from public and private funds for our research anddevelopment projects. The grant income for a given period is recognized as a cost reimbursement and is typically based on the time and the costs that we have spent on the specific project during that period.

We have historically met the requirements to receive a tax credit in Denmark of up to 5.5 million Danish Kroner per yearfor losses resulting from research and development costs of up to 25 million Danish Kroner per year. The tax credit is presented as a reduction to research and development expense in the statements of operations.

We use our personnel and infrastructure resources across multiple research and development programs directed towardidentifying and developing product candidates. We generally have not tracked our research and development expenses on a program-by-program basis. Substantially all ofour direct research and development expenses in the years ended December 31, 2020 and 2019 were on IO102-IO103 and consisted primarily of external costs, such as consultants, third-party contract organizations that conduct research anddevelopment activities on our behalf, costs related to production of preclinical and clinical materials, including fees paid to contract manufacturers, and laboratory and vendor expenses related to the execution of our ongoing and plannedpreclinical studies and clinical trials.

We expect our research and development expenses to increase substantially forthe foreseeable future as we continue to invest in research and development activities related to developing our product candidates, including investments in conducting clinical trials, manufacturing and otherwise advancing our programs. The processof conducting the necessary clinical research to obtain regulatory approval is costly and time-consuming, and the successful development of our product candidates is highly uncertain.

Because of the numerous risks and uncertainties associated with product development and the current stage of development ofour product candidates and programs, we cannot reasonably estimate or know the nature, timing and estimated costs necessary to complete the remainder of the development of our product candidates or programs. We are also unable to predict if, when,or to what extent we will obtain approval and generate

 

87


Table of Contents

revenues from the commercialization and sale of our product candidates. The duration, costs and timing of preclinical studies and clinical trials and development of our product candidates willdepend on a variety of factors, including:

 

  

successful completion of preclinical studies and of clinical trials for IO102-IO103, IO112, and our othercurrent product candidates and any future product candidates;

 

  

successful enrollment and completion of our planned Phase 3 clinical trial for IO102-IO103, Phase 2IO102-IO103 basket trials, and any clinical trials for future product candidates;

 

  

data from our clinical programs that support an acceptable risk-benefit profile of our product candidates inthe intended patient populations;

 

  

acceptance by the FDA, regulatory authorities in Europe, or other regulatory agencies of the IND applications,clinical trial applications and/or other regulatory filings for IO102-IO103, IO112, and our other current product candidates and any future product candidates;

 

  

expansion and maintenance of a workforce of experienced scientists and others to continue to develop ourproduct candidates;

 

  

successful application for and receipt of marketing approvals from applicable regulatory authorities;

 

  

obtainment and maintenance of intellectual property protection and regulatory exclusivity for our productcandidates;

 

  

arrangements with third-party manufacturers for, or establishment of, commercial manufacturing capabilities;

 

  

establishment of sales, marketing and distribution capabilities and successful launch of commercial sales ofour products, if and when approved, whether alone or in collaboration with others;

 

  

acceptance of our products, if and when approved, by patients, the medical community and third-party payors;

 

  

effective competition with other therapies;

 

  

obtainment and maintenance of coverage, adequate pricing and adequate reimbursement from third-party payors,including government payors;

 

  

maintenance, enforcement, defense and protection of our rights in our intellectual property portfolio;

 

  

avoidance of infringement, misappropriation or other violations with respect to others’ intellectualproperty or proprietary rights; and

 

  

maintenance of a continued acceptable safety profile of our products following receipt of any marketingapprovals.

We may never succeed in achieving regulatory approval for any of our product candidates. Wemay obtain unexpected results from our preclinical studies and clinical trials. We may elect to discontinue, delay or modify clinical trials of some product candidates or focus on others. A change in the outcome of any of these factors could mean asignificant change in the costs and timing associated with the development of our current and future preclinical and clinical product candidates. For example, if the FDA or another regulatory authority were to require us to conduct clinical trialsbeyond those that we currently anticipate will be required for the completion of clinical development, or if we experience significant delays in execution of or enrollment in any of our preclinical studies or clinical trials, we could be required toexpend significant additional financial resources and time on the completion of preclinical and clinical development.

Research and development activities account for a significant portion of our operating expenses. We expect our research anddevelopment expenses to increase for the foreseeable future as we continue to implement our

 

88


Table of Contents

business strategy, which includes advancing IO102-IO103 through clinical development and other product candidates further into clinical development, expanding our research and developmentefforts, including hiring additional personnel to support our research and development efforts, and seeking regulatory approvals for our product candidates that successfully complete clinical trials. In addition, product candidates in later stagesof clinical development generally incur higher development costs than those in earlier stages of clinical development, primarily due to the increased size and duration of later-stage clinical trials. As a result, we expect our research anddevelopment expenses to increase as our product candidates advance into later stages of clinical development. However, we do not believe that it is possible at this time to accurately project total program-specific expenses throughcommercialization. There are numerous factors associated with the successful commercialization of any of our product candidates, including future trial design and various regulatory requirements, many of which cannot be determined with accuracy atthis time based on our stage of development.

General and Administrative Expenses

Our general and administrative expenses consist primarily of personnel costs, depreciation expense and other expenses foroutside professional services, including legal fees relating to patent and corporate matters, human resources, audit and accounting services and facility-related fees not otherwise included in research and development expenses. Personnel costsconsist of salaries, benefits and equity-based compensation expense, for our personnel in executive, finance and accounting, business operations and other administrative functions. We expect our general and administrative expenses to increase overthe next several years to support our continued research and development activities, manufacturing activities, increased costs of expanding our operations and operating as a public company. These increases will likely include increases related tothe hiring of additional personnel, fees to outside consultants, lawyers and accountants, and increased costs associated with being a public company such as expenses related to services associated with maintaining compliance with Nasdaq listingrules and SEC requirements, director and officer insurance premiums and investor relations costs.

Other Expense,Net

Our other expense, net is comprised of:

 

  

Foreign exchange: Our functional currency is the Euro. Transactions denominated in currencies other than theEuro result in exchange gains and losses that are recorded in our statements of operations.

 

  

Fair value adjustments on convertible notes: We have elected to account for our convertible notes at fairvalue, with corresponding adjustments to fair value accounted for as gains and losses in our statements of operations.

 

  

Interest expense: For the years ended December 31, 2020 and 2019, we incurred interest expense on accountbalances with banks and vendors.

General and administrative expenses were $1.7 million for the year endedDecember 31, 2020, compared to $2.0 million for the year ended December 31, 2019. The decrease of $0.3 million was primarily related to a reduction in travel expenses related to conferences and business activities.

Other Expense, Net

Other expense, net for the years ended December 31, 2020 and 2019 were a net expense of $1.9 million and$0.8 million, respectively. The increase of $1.1 million was due to the following:

 

  

Net foreign exchange gains were $114,000 for the year ended December 31, 2020 and net foreign exchangelosses were $43,000 for the year ended December 31, 2019.

 

  

Fair value adjustments on our convertible notes were losses of $2.0 million and $0.8 million for theyears ended December 31, 2020 and 2019, respectively.

Liquidity and Capital Resources

Sources of Liquidity

Our operations to date have been financed primarily by aggregate net proceeds of $101.2 million from the issuance ofconvertible preference shares, convertible notes and class A ordinary shares, including the issuance of 505,520 shares of Class C convertible preference shares for $61.5 million in January 2021 and the issuance of 35,825 shares ofClass C convertible preference shares for $4.2 million in March 2021. As a result of entering into a collaboration agreement with Merck in September 2021, the number of class C preference shares issued in March 2021 was adjusted downwardto 32,568 class C preference shares. Since inception, we have had significant operating losses. Our net loss was $45.5 for the six months ended June 30, 2021 and $12.0 million and $10.7 million for the years ended December 31,2020 and 2019, respectively. As of December 31, 2020, we had an accumulated deficit of $83.9 million and $54.8 million in cash and cash equivalents. Our primary use of cash is to fund operating expenses, which consist primarily ofresearch and development expenditures, and to a lesser extent, general and administrative expenditures. Cash used to fund operating expenses is impacted by the timing of when we pay these expenses, as reflected in the change in our outstandingaccounts payable and accrued expenses.

We currently expect that our cash and cash equivalents of $54.8 million as ofJune 30, 2021, together with $84.1 million of gross proceeds from the issuance of second tranche Class C convertible preference shares in October 2021, together with the proceeds of this offering, will be sufficient to fund ouroperating expenses and capital requirements through                . However, additional funding will be necessary to fund our future clinical and pre-clinical activities and we do not currently have any. If we are unable to obtain funding, we could be forced to delay, reduce or eliminate our research and development programs, product portfolio expansion orcommercialization efforts, which could adversely affect our business prospects and our ability to continue operations.

Funding Requirements

Any product candidates we may develop may never achieve commercialization and we anticipate that we will continue to incurlosses for the foreseeable future. We expect that our research and development expenses, general and administrative expenses, and capital expenditures will continue to increase. As a result, until such time, if ever, as we can generate substantialproduct revenue, we expect to finance our cash needs through a combination of equity offerings, debt financings or other capital sources, including potentially collaborations, licenses and other similar arrangements. Our primary uses of capital are,and we expect will continue to be, compensation and related expenses; costs related to third-party clinical research, manufacturing and development services; costs relating to the build-out of our headquartersand other offices, our laboratories and our manufacturing facility; license payments or milestone obligations that may arise; laboratory expenses and costs for related supplies; clinical costs; manufacturing costs; legal and other regulatoryexpenses and general overhead costs.

Based upon our current operating plan, we believe that the net proceeds from thisoffering, together with our existing cash and cash equivalents of $54.8 million as of June 30, 2021, and the $84.1 million of gross proceeds from the sale and issuance of our second tranche Class C preference shares in October2021, will be sufficient to continue funding our development activities through                 . To finance our operations beyond that point we will need to raiseadditional capital, which cannot be assured. We have based this estimate on assumptions that may prove to be wrong, and we could utilize our available capital resources sooner than we currently expect. We will continue to require additionalfinancing to advance our current product candidates through clinical development, to develop, acquire or in-license other potential product candidates and to fund operations for the foreseeable future. We willcontinue to seek funds through equity offerings, debt financings or other capital sources, including potentially collaborations, licenses and other similar arrangements. However, we may be unable to raise additional funds or enter into such otherarrangements when needed on favorable terms or at all. If we do raise additional capital through public or private equity offerings, the ownership interest of our existing stockholders, including investors in this offering, will be diluted, and theterms of these securities may include liquidation or other preferences that adversely affect our stockholders’ rights. If we raise additional capital through debt financing, we may be subject to covenants limiting or restricting our ability totake specific actions, such as incurring additional debt, making capital expenditures or declaring dividends. Any failure to raise capital as and when needed could have a negative impact on our financial condition and on our ability to pursue ourbusiness plans and strategies. If we are unable to raise capital, we will need to delay, reduce or terminate planned activities to reduce costs.

Because of the numerous risks and uncertainties associated with research, development and commercialization of pharmaceuticalproducts, we are unable to estimate the exact amount of our operating capital requirements. Our future funding requirements will depend on many factors, including, but not limited to:

 

  

the progress, costs and results of our ongoing and planned clinical trials of IO102-IO103, as well as ourplanned trials for our other product candidates;

 

  

the scope, progress, results and costs of discovery research, preclinical development, laboratory testing andclinical trials for our product candidates, including our ongoing clinical trials of IO102-IO103;

 

  

the impacts of the COVID-19 pandemic;

 

  

the number of, and development requirements for, other product candidates that we pursue;

 

  

the costs, timing and outcome of regulatory review of our product candidates;

 

  

our ability to enter into contract manufacturing arrangements for supply of active pharmaceutical ingredient,or API, and manufacture of our product candidates and the terms of such arrangements;

 

  

our ability to establish and maintain strategic collaborations, licensing or other arrangements and thefinancial terms of such arrangements;

 

94


Table of Contents
  

the payment or receipt of milestones and receipt of other collaboration-based revenues, if any;

 

  

the costs and timing of any future commercialization activities, including product manufacturing, sales,marketing and distribution, for any of our product candidates for which we may receive marketing approval;

 

  

the amount and timing of revenue, if any, received from commercial sales of our product candidates for whichwe receive marketing approval;

 

  

the costs and timing of preparing, filing and prosecuting patent applications, maintaining and enforcing ourintellectual property and proprietary rights and defending any intellectual property-related claims;

 

  

the extent to which we acquire or in-license other products, productcandidates, technologies or data referencing rights;

 

  

enrollment for our upcoming Phase 3 registration trial, theIOB-013/KN-D18 trial;

 

  

the ability to receive additional non-dilutive funding, includinggrants from organizations, public institutions and foundations;

 

  

addition of operational, financial and management information systems and personnel, including personnel tosupport our drug development, any future commercialization efforts and our transition to a public company; and

 

  

the costs of operating as a public company.

Further, our operating plans may change, and we may need additional funds to meet operational needs and capital requirementsfor clinical trials and other research and development activities. Because of the numerous risks and uncertainties associated with the development and commercialization of our product candidates, we are unable to estimate the amounts of increasedcapital outlays and operating expenditures associated with our current and anticipated product development programs.

Contractual Obligations andCommitments

We enter into contracts in the normal course of business with third-party service providers for clinicaltrials, preclinical research studies and testing, manufacturing and other services and products for operating purposes. These contracts generally provide for termination upon notice of 30 to 90 days, and therefore, we believe that our non-cancelable obligations under these agreements are not material and we cannot reasonably estimate the timing of if and when they will occur. However, in the event of a termination of any contracts with CROs orother institutions and with respect to active patients enrolled in our clinical trials, we may be financially obligated for a period beyond the contractual termination notice periods. As of June 30, 2021, we had commitments of approximately$5.0 million with CROs and other institutions for the ongoing clinical trial services due within approximately 21 months. Additionally, upon the completion of this offering, we will be obligated to make payments to Herlev in the aggregateamount of approximately DKK 15.2 million (which is approximately $2.5 million based on the exchange rate of DKK 6.08 to one U.S. dollar on December 31, 2020).

We may also enter into additional research, manufacturing, supplier, lease and other agreements in the future, which mayrequire up-front payments and even long-term commitments of cash.

Critical Accounting Policies and SignificantJudgments and Estimates

Our management’s discussion and analysis of our financial condition and results ofoperations is based on our financial statements, which have been prepared in accordance with U.S. GAAP. The preparation of these financial statements requires us to make estimates and assumptions that affect the reported amounts of assets andliabilities and the disclosure of contingent assets and liabilities at the date of the financial statements, as well as the reported expenses incurred during the reporting periods. Our estimates are based on our historical experience

 

95


Table of Contents

and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilitiesthat are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. We believe that the accounting policies discussed below are critical to understanding our historical andfuture performance, as these policies relate to the more significant areas involving management’s judgments and estimates.

Going Concern

Our evaluation of our ability to continue as a going concern requires us to evaluate our future sources and uses of cashsufficient to fund our currently expected operations in conducting research and development activities one year from the date our financial statements are issued. We evaluate the probability associated with each source and use of cash resources inmaking our going concern determination. The research and development of pharmaceutical products is inherently subject to uncertainty.

Research and Development Costs

We incur substantial expenses associated with clinical trials. Accounting for clinical trials relating to activities performedby CMO’s, CRO’s and other external vendors requires management to exercise significant estimates in regard to the timing and accounting for these expenses. We estimate costs of research and development activities conducted by serviceproviders, which include, the conduct of sponsored research, pass-through costs, preclinical studies and contract manufacturing activities. The diverse nature of services being provided under CRO and other arrangements, the different compensationarrangements that exist for each type of service and the lack of timely information related to certain clinical activities complicates the estimation of accruals for services rendered by CROs and other vendors in connection with clinical trials. Werecord the estimated costs of research and development activities based upon the estimated amount of services provided but not yet invoiced and include these costs in the accrued and other current liabilities or prepaid expenses on the balancesheets and within research and development expense on the statements of operations. In estimating the duration of a clinical study, we evaluate the start-up, treatment andwrap-up periods, compensation arrangements and services rendered attributable to each clinical trial and fluctuations are regularly tested against payment plans and trial completion assumptions.

We estimate these costs based on factors such as estimates of the work completed and budget provided and in accordance withagreements established with our collaboration partners and third-party service providers. We make significant judgments and estimates in determining the accrued liabilities and prepaid expense balances in each reporting period. As actual costsbecome known, we adjust our accrued liabilities or prepaid expenses. We have not experienced any material differences between accrued costs and actual costs incurred since our inception.

Our expenses related to clinical trials are based on estimates of patient enrollment and related expenses at clinicalinvestigator sites as well as estimates for the services received and efforts expended pursuant to contracts with multiple research institutions, CMO’s and CROs that may be used to conduct and manage clinical trials, chemistry and testing andmanufacturing services on our behalf. We generally accrue expenses related to clinical trials based on contracted amounts applied to the level of patient enrollment and activity. If timelines or contracts are modified based upon changes in theclinical trial protocol or scope of work to be performed, we modify our estimates of accrued expenses accordingly on a prospective basis.

Equity-based Compensation

Prior to this offering, we issued equity-based compensation awards through the granting of warrants, which generally vest overa four-year period. We did not grant any warrants during the six months ended June 30, 2021 and the years ended December 31, 2020 and 2019. In July and August 2021, we granted 196,198 warrants with

 

96


Table of Contents

an exercise price of $69.54 to certain employees, board members and advisors. We account for equity-based compensation in accordance with ASC 718, Compensation-Stock Compensation (ASC718). In accordance with ASC 718, compensation cost is measured at estimated fair value and is included as compensation expense over the vesting period during which service is provided in exchange for the award.

We use a Black-Scholes option pricing model to determine fair value of our warrants. The Black-Scholes option pricing modelincludes various assumptions, including the fair value of class A ordinary shares, expected life of warrants, the expected volatility and the expected risk-free interest rate. These assumptions reflect our best estimates, but they involve inherentuncertainties based on market conditions generally outside our control. As a result, if other assumptions had been used, equity-based compensation cost could have been materially impacted. Furthermore, if we use different assumptions for futuregrants, share-based compensation cost could be materially impacted in future periods.

We will continue to use judgment inevaluating the assumptions utilized for our equity-based compensation expense calculations on a prospective basis. In addition to the assumptions used in the Black-Scholes model, the amount of equity-based compensation expense we recognize in ourfinancial statements includes warrant forfeitures as they occurred.

As there has been no public market for our class Aordinary shares to date, our board of directors, with input from management, has determined the estimated fair value of our class A ordinary shares as of the date of each warrant grant considering our then-most recently available third-partyvaluation of class A ordinary shares. Valuations are updated when facts and circumstances indicate that the most recent valuation is no longer valid, such as changes in the stage of our development efforts, various exit strategies and their timing,and other scientific developments that could be related to our valuation, or, at a minimum, annually. Third-party valuations were performed in accordance with the guidance outlined in the American Institute of Certified Public Accountants’Accounting and Valuation Guide, Valuation of Privately-Held-Company Equity Securities Issued as Compensation.

Theestimates of fair value of our class A ordinary shares are highly complex and subjective. There are significant judgments and estimates inherent in the determination of the fair value of our class A ordinary shares. These judgments and estimatesinclude assumptions regarding our future operating performance, the time to completing an initial public offering (IPO) or other liquidity event, the related valuations associated with these events, and the determinations of the appropriatevaluation methods at each valuation date. The assumptions underlying these valuations represent our best estimates, which involve inherent uncertainties and the application of management judgment. If we had made different assumptions, ourequity-based compensation expense, net loss and net loss per share applicable to class A ordinary shareholders could have been materially different.

Following the completion of this offering, we intend to determine the fair value of our common stock based on the closingprice of our common stock on the date of grant as reported on the Nasdaq Global Market.

Determination of the FairValue of Convertible Note and Class B Preference Shares

In July 2019, we issued convertible notes to existingrelated party investors for proceeds of $9.0 million. Upon issuance, we elected the fair value option to account for the convertible notes, with any subsequent changes in fair value being recognized through the statements of operations as otherincome (expense) until the convertible notes are settled. We have not recorded interest expense separate from those fair value adjustments.

We determine fair value of the convertible notes on issuance and at December 31, 2019 using a scenario-based valuationmethod and a Monte Carlo simulation model with inputs based on certain subjective assumptions, including (a) estimated conversion dates, (b) expected stock price volatility, (c) a risk-free interest rates, and (d) implied debtyields. This approach results in the classification of these securities as Level 3 of the fair value hierarchy.

Table of Contents

On conversion in April 2020, we determined the fair value of the convertiblenotes with reference to the class B preference shares into which the convertible notes were converted into (142,437 shares).

Income Taxes

Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between thefinancial statement carrying amounts of existing assets and liabilities and their respective tax bases, and operating losses and tax credit carry forwards. Deferred tax assets and liabilities are measured using enacted statutory tax rates expectedto apply to taxable income in the jurisdictions and years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the periodthat includes the enactment date.

Based on the level of historical operating results and projections for the taxableincome for the future, we have determined that it is more likely than not that our net deferred tax assets will not be realized. Accordingly, we have recorded a full valuation allowance to reduce our net deferred tax assets.

We recognize tax benefits from uncertain tax positions only if (based on the technical merits of the position) it is morelikely than not that the tax positions will be sustained on examination by the tax authority. The tax benefits recognized in the financial statements from such positions are measured based on the largest amount that is more than 50% likely to berealized upon ultimate settlement. We recognize interest and penalties related to unrecognized tax benefits within the provision for taxes in our statements of operations and comprehensive loss.

We operate in Denmark and may be subject to audits from various tax authorities. Management’s judgment is required indetermining our provision for income taxes, our deferred tax assets and liabilities, liabilities for uncertain tax positions, and any valuation allowance recorded against our net deferred tax assets. We will monitor the extent to which our deferredtax assets may be realized and adjust the valuation allowance accordingly.

Recently Adopted AccountingPronouncements

Refer to Note 2, “Summary of Significant Accounting Policies,” in the accompanyingnotes to our financial statements for the years ended December 31, 2020 and 2019 appearing elsewhere in this prospectus for a discussion of recent accounting pronouncements.

Off-balance Sheet Arrangements

During the periods presented, we did not have, nor do we currently have, anyoff-balance sheet arrangements as defined under SEC rules.

Quantitative and Qualitative Disclosures AboutMarket Risk

We are a smaller reporting company as defined by Item 10 of RegulationS-K and are not required to provide the information otherwise required under this item.

Emerging GrowthCompany Status

As an EGC under the JOBS Act, we may delay the adoption of certain accounting standards until such timeas those standards apply to private companies. Other exemptions and reduced reporting requirements under the JOBS Act for EGCs include presentation of only two years of audited financial statements in a registration statement for an IPO, anexemption from the requirement to provide an auditor’s report on internal controls over financial reporting pursuant to Section 404(b) of the Sarbanes-Oxley Act, an exemption from any requirement that may be adopted by the Public CompanyAccounting Oversight Board regarding mandatory audit firm rotation, and less extensive disclosure about our executive compensation arrangements.

Table of Contents

In addition, the JOBS Act provides that an EGC can take advantage of anextended transition period for complying with new or revised accounting standards. This provision allows an EGC to delay the adoption of some accounting standards until those standards would otherwise apply to private companies. We have elected touse this extended transition period for complying with new or revised accounting standards that have different effective dates for public and private companies until the earlier of the date we (i) are no longer an emerging growth company or(ii) affirmatively and irrevocably opt out of the extended transition period provided in the JOBS Act. As a result, our financial statements may not be comparable to companies that comply with new or revised accounting pronouncements as ofpublic company effective dates.

We may remain classified as an EGC until the end of the fiscal year following the fifthanniversary of this offering, although if the market value of our common stock that is held by non-affiliates exceeds $700 million as of June 30 of any year before that time, or if we have annualgross revenues of $1.07 billion or more in any fiscal year, we would cease to be an EGC as of December 31 of the applicable year. We also would cease to be an EGC if we issue more than $1.0 billion ofnon-convertible debt over a three-year period.

BUSINESS

Overview

We are aclinical-stage biopharmaceutical company developing novel, immune-modulating cancer therapies based on our T-win technology platform. Our product candidates are designed to induce the immune system to simultaneously target and disrupt multiplepathways that regulate tumor-induced immunosuppression. We believe this represents a paradigm shift in the management of cancer and that our product candidates have the potential to become cornerstones of the treatment regimens of multiple solidtumors. Our lead product candidate, IO102-IO103, is designed to target the immunosuppressive mechanisms mediated by key immunosuppressive proteins such as IDO and PD-L1. In a single-arm Phase 1/2 clinical trial of 30 patients with metastaticmelanoma with the primary objective to investigate safety and tolerability, secondary objective to investigate immunogenicity and tertiary objective to investigate clinical efficacy, IO102-IO103, in combination with nivolumab, demonstrated anability to induce meaningful tumor regression and establish durable antitumor response while achieving a manageable tolerability profile for patients. The clinical efficacy endpoints in this trial include OR, PFS and OS. In this trial, we haveobserved a confirmed ORR of 73% and a CRR of 47%. Based on the results from this trial, IO102-IO103, in combination with pembrolizumab was granted BTD by the FDA for treatment of unresectable/metastatic melanoma and we are currently planning apotentially registrational Phase 3 trial for IO102-IO103 in combination with pembrolizumab.

Our T-win platform is a novel approach to cancer immunotherapy designed to activate naturally occurring T cells to target immunosuppressive mechanisms. Our T-win productcandidates are designed to employ a dual mechanism of action: (1) direct killing of immunosuppressive cells, including both tumor cells and genetically stable cells in the TME, that express IDO and PD-L1and (2) modulation of the TME into a more pro-inflammatory, anti-tumor environment. Our T-win technology is built upon our team’s deep understanding of bothTME and a tumor’s ability to evade surveillance and destruction by the immune system. Our approach is in contrast to previous methods that have sought to either block singular immunosuppressive pathways or to direct the immune system againstspecific identified antigens expressed by tumor cells.

We are developing a pipeline of product candidates that leverageour T-win technology platform to address targets within the TME. In addition to melanoma, we plan to evaluate IO102-IO103 in multiple solid tumor indications to potentially expand the market opportunity forIO102-IO103. We are also focusing on additional targets that play key roles in immunosuppression and that are expressed in a broad range of solid tumors. Our pipeline of product candidates is summarized in the table below.

Table of Contents

Our lead product candidate, IO102-IO103, combines our two fully-owned, novelimmunotherapeutics, IO102 and IO103, which are designed to target IDO+ and PD-L1+ target cells, respectively. IDO and PD-L1 are often dysregulated and over-expressed ina wide range of solid tumors, and result in the inhibition of the body’s natural pro-inflammatory anti-tumor response within the TME. IO102-IO103 is designed to employ our novel dual mechanism of actionapproach. This is in contrast to previous approaches which have sought to block singular immunosuppressive pathways or to direct the immune system against specific identified antigens expressed by tumor cells. By combining IO102 and IO103 in asingle treatment regimen, we also aim to provide a synergistic effect on tumors.

On December 14, 2020, the FDAgranted us BTD for IO102-IO103 in combination with pembrolizumab for the treatment of patients with unresectable or metastatic melanoma based on data from the Phase 1/2 clinical trial, MM1636. BTD enables us to solicit more frequent and intensiveguidance from the FDA as to how to conduct an efficient development program for IO102-IO103. The MM1636 trial is an investigator initiated, single-arm Phase 1/2 trial of 30 antiPD-1/PD-L1 naïve patients with metastatic melanoma receiving IO102-IO103 and nivolumab, ananti-PD-1 monoclonal antibody. In this trial, investigators initially observed an ORR of 80% (24 out of 30 patients); however, two of 24 patients in which a response wasobserved progressed before subsequent radiological confirmation, which resulted in a confirmed ORR of 73%. In addition, 47% of patients achieved a CR, or complete elimination of their tumors based on RECIST 1.1 definitions. While a total of fivepatients (17%) experienced a high-grade adverse event (grade 3-5) as further discussed in the section titled “—Our Product Candidates—Dual Epitope IO102-IO103—Development of Dual Epitope IO102-IO103 in the First-lineSetting—Tolerability,” based on the 17% discontinuation rate of treatment with both nivolumab and IO102-IO103, data from this trial suggests a manageable tolerability profile for patients. In addition, we have observed treatment-inducedinfiltration of CD3/CD8 T cells into the tumor site in responding patients and detected IO102+IO103-specific T cells in tumors after treatment in correlative biomarker data where this was analyzed. We are currently planning a Phase 3potentially registrational trial for IO102-IO103, the IOB-013/KN-D18 trial, in combination with pembrolizumab, which we expect to initiate by the end of 2021. While theMM1636 trial investigates IO102-IO103 in combination with nivolumab, we have made the commercial decision to investigate IO102-IO103 in combination with pembrolizumab in the upcoming Phase 3 trial. Nivolumab and pembrolizumab are both IgG4subclass antibodies that target the PD-1 receptor. In a comparative data analysis by Moser (Annals of Oncology 2020), researchers found no difference between the effectiveness of frontline pembrolizumab and nivolumab in patients with advancedmelanoma. The Phase 3 trial will include a concurrent evaluation of the initial participants to allow for an assessment of safety, or safety run in. The pembrolizumab for this trial will be supplied by Merck pursuant to a Clinical TrialCollaboration and Supply Agreement that we entered into in September 2021.

We plan to broaden the development ofIO102-IO103 to several other first-line solid tumor indications. We intend to conduct a Phase 2 basket trial, the IOB-022 trials which will enable us to investigate multiple first-line solid tumor indications in antiPD-1/PD-L1 treatment naïve patients with metastatic disease. Our planned basket trial will investigate the safety and efficacy of IO102-IO103 in combination withpembrolizumab in NSCLC with PD-L1 ³50%, SCCHN, and UBC. In addition to first-line cancer indications, we also plan to investigate IO102-IO103 when used before orafter curatively intended surgery as a neo-adjuvant/adjuvant therapy. As with our targeted first-line cancer indications, we plan to conduct a Phase 2 basket trial, the IOB-032 trial, which will enable usto investigate multiple first-line solid tumor indications in anti PD-1/PD-L1 naïve settings focused initially on melanoma and SCCHN.

Our development of IO102-IO103 is based on our prior separate development of IO102 and IO103. IO102 is our fully-owned novelproduct candidate containing a single IDO-derived peptide sequence designed to engage and activate IDO-specific human T cells. IDO small molecule inhibitors have shownclinical potential in combination with PD-1 antibodies in early clinical trials, but have not been able to demonstrate the same level of efficacy in later-stage clinical trials. Our Phase 1 non-randomized trial of IO101, our first generation IDOtherapy, in NSCLC resulted in proof of concept for our approach, with 47% of patients displaying clinical benefit and an OS of 26 months in the treatment arm compared to 8 months in the group receiving standard of care. There were no grade 3 orhigher adverse events (AEs). IO102 is currently being tested in a randomized Phase 1/2 trial in combination with pembrolizumab standard-of-care in first-linetreatment of patients with metastatic

NSCLC. IO103 is our fully-owned, novel product candidate containing a single PD-L1-derived peptide designed toengage and activate PD-L1 specific human T cells. Continued clinical development of IO102 and IO103 will be focused on their use in our dual- and multi-antigen approaches.

IO112 is our fully-owned, novel product candidate containing a single Arginase1-derived peptide designed to engage and activate Arginase 1-specific human T cells. IO112 is designed to target T cells that recognize epitopes derived from Arginase 1,which is an immunoregulatory enzyme highly expressed in difficult-to-treat tumors associated with high levels of MDSCs including colorectal, breast, prostate andpancreatic and ovarian cancers. Arginase overexpression is a well-documented tumor escape mechanism. We plan to file an IND/CTA for IO112 in the first half of 2022 and move into a Phase 1/2 trial in mid-2022 in combination with IO102 and IO103.

In addition to IO102, IO103 and IO112, we are evaluating additional potential product candidates that we believe havepotential for use in solid tumors. All our compounds in preclinical development are designed to target well-documented immunosuppressive molecules that are known to be overexpressed in the TME across a wide range of tumors. These targets provideadditional opportunities across multiple cancer indications.

We were established in December 2014 as a spin-off of National Cancer for Center Immune Therapy at Herlev University Hospital in Denmark. We have assembled a seasoned management team and board of directors with extensive experience in developing noveloncology therapies, including advancing product candidates from preclinical research through to clinical development and ultimately to regulatory approval.

Our Strategy

To achieve our goals, we aim to leverage our T-win platform to transform cancertreatments by creating a broad portfolio of immuno-oncology therapies focused on targets within the TME.

The key elementsof our strategy are to:

 

  

Advance our lead product candidate, IO102-IO103, toward approval in combination with anti-PD-1 therapy in first-line treatment of advanced melanoma. We have been granted BTD by the FDA based on a confirmed ORR of 73% and CRR of 47% in MM1636, thePhase 1/2 clinical trial of IO102-IO103 in combination with nivolumab in first-line treatment of patients with melanoma. By the end of 2021, we plan to initiate a randomized, potentially registration-enabling Phase 3 trial, theIOB-013/KN-D18 trial, combining IO102-IO103 with an anti-PD-1 monoclonal antibody in first line advanced melanoma patients regardless of BRAF mutational status;

 

  

Broaden clinical development of IO102-IO103 into other first-line solid tumor settings through baskettrials in the first line metastatic and neo-adjuvant / adjuvant treatment settings. We plan to initiate a randomized Phase 2 basket trial, IOB-022, of IO102-IO103 in combination with pembrolizumab in the first line solid tumor setting. Thisbasket trial will enroll PD-1/PD-L1 treatment naïve patients with metastatic disease, including NSCLC, SCCHN and UBC. We expect to begin enrollment of patients expressing PD-L1 >= 50% in the NSCLC arm of this trial by the end of 2021. Wealso plan to initiate a randomized Phase 2 basket trial, IOB-032, of IO102-IO103 in combination with anti-PD-1 antibody therapy in the neo-adjuvant / adjuvant treatment setting. In this trial, combination therapy will be used

before and after curatively intended surgery. This basket trial will enable us to investigate multiple solid tumor indications in anti PD-1/ PD-L1 naive patients, and will focus initially onmelanoma and SCCHN. We expect to begin enrollment of patients in the melanoma arm of this trial in the first half of 2022. These two basket trials build on the data that we have generated from prior trials of our single epitope product candidates,IO102 and IO103, including the anti-tumor activity that we have observed with the use of our first generation IDO compound in NSCLC;

 

  

Leverage our T-win technology platform to design and advance aportfolio of novel immunotherapy product candidates, including IO112 and additional future product candidates. Since inception, our T-win platform has allowed us to rapidly identify and develop multiplepipeline candidates. Our next product candidate, IO112, targets Arginase 1 which is over-expressed in solid tumors where MDSCs are known to play key roles in immune resistance. In mid-2022, subject to clearance of an IND for IO112, we intend toinitiate a Phase 1/2 clinical trial in patients with advanced solid tumors. We are continuing to evaluate other targets within the TME and intend to leverage our T-win platform to bring additional productcandidates into the clinic over time which could be used alone or in combination with other candidates.

 

  

Strengthen our position in the immunotherapy field through the continuous innovation and expansion of our T-win platform. We have extensive knowledge about the characterization of immunosuppressive mechanisms in the TME and pharmacology. We plan to continue investing in our platform in order to stay at the forefrontof developments in the space. Our platform is supported by a strong patent portfolio consisting of 13 different families, filed in all major markets with a long exclusivity periods. We plan to continue investing in intellectual property to supportour platform and product candidates;

 

  

Maximize the value of our product candidates and pipeline by selectively entering into strategiccollaborations. We hold worldwide development and commercial rights to our pipeline of compounds, and we intend to commercialize our product candidates, if approved, in key geographies. We have, and may in the future, enter into collaborationsthat grant us access to certain compounds owned by third parties to enable therapeutic combinations that could enhance the clinical and commercial potential of our product candidates. For example, we have entered into a non-exclusive, clinical supply agreement with MSD International GmbH (MSDIG)/Merck, to evaluate IO102 in combination with pembrolizumab plus chemotherapy; and

 

  

Build a leading immuno-oncology company while maintaining a strong culture of innovation, valuing diversityand putting patients at the center of everything we do. We will continue to apply our deep understanding of the TME to the discovery and development of novel immuno-oncology therapies that have the potential to provide breakthroughs for cancerpatients who are currently underserved by available therapies. We place a high value on the diversity of our team – including gender, background and expertise – to foster this culture of innovation.

Our Approach to Cancer Immunotherapy

Our product candidates are designed to induce the immune system to simultaneously target and disrupt multiple pathways thatregulate tumor-induced immunosuppression. We believe this represents a paradigm shift in the management of cancer and that our product candidates have the potential to become cornerstones of the treatment regimens of multiple solid tumors. Our T-win technology is built upon our team’s deep understanding of both the TME and a tumor’s ability to evade surveillance and destruction by the immune system.

The Role of the Immune System in Fighting Cancer

The Immune System

The immune system is a dynamic and self-regulating network of cells and molecules that cooperate to help the body fightdisease. It is able to detect pathogens and can distinguish abnormal cells, such as tumor cells, from healthy tissue. The immune system has evolved to detect such dangers to the body through the detection of molecules or

 

103


Table of Contents

molecular structures called antigens. When exposed to pathogens or abnormal cells, the immune system responds by recognition of antigens and becomes activated to defend against them. The firstline of biological defense is a general, rapid response by the innate immune system which is essential for immediate recognition and attack of pathogens as well as tumor cells. This innate response then activates and triggers a more targetedresponse by the adaptive immune system. Through such adaptive immune responses, the body can develop long-term immunity, or immunologic memory, to specific pathogens and other threats. Immunologic memory is established through generation of specificB cells and T cells, equipping the body to recognize, counteract and neutralize pathogens and other threats, such as cancer cells.

The intricate system of how immune cells interact and propagate a signal to elicit an immune response in cancer is known astumor immune regulation. Successful antitumor immunity requires optimal interactions between immune and non-immune constituents of the TME. The immune system comprises both activating and suppressing functionsbuilt up by a myriad of different cell types. These various immune cells function to activate or suppress immune activity. We have described some of the key cellular factors contributing to anti-tumor immunity below and have classified them asimmune activators or immune suppressors. However, many of these cells types can differentiate and acquire distinct functions in response to changing circumstances, known as cellular plasticity, which allows cells to switch from being immuneactivating to immune suppressing, or the reverse, based on certain immune triggers.

The Key Immune Activators and Suppressors in Anti-tumor Responses

 

Cell types  Immune Activators  Immune Suppressors

Antigen Presenting Cells (APCs)

A group of immune cell types that mediate cellular immune responses by processing and presenting antigens to lymphocytes.

  

Macrophages and Dendritic cells

Both termed professional APCs, because of their ability to initiate a T cell response to novel antigens.

  

Tumor-associated macrophages (TAMs), tolerogenic DCs and myeloid-derived suppressor cells (MDSCs)

These are part of the heterogeneous population of APCs that inhibits T cell functions.

 

   

T cells / T lymphocytes

Specialized white blood cells that recognize and destroy infected or unhealthy cells, such as tumor cells.

  

Effector T cells

Effector T cells consists of two main groups:

 

CD4+ T Cells

Also known as helper T cells, CD4+ T cells produce cytokines and help maximize theexpansion of the CD8+ T cell population in a primary immune response and facilitate the generation of specific memory CD8+ T cells; and

 

CD8+ T Cells

Also known as cytotoxic T cells, CD8+ T cells kill tumor cells, as well as infected anddamaged cells. They express T cell receptors (TCRs), which recognize and bind to specific antigens expressed by cancer cells and infected cells which are presented on the surface of the cells.

 

 

  

Regulatory T cells (Tregs)

Tregs suppress activation, proliferation and cytokine production of CD4+ and CD8+ T cells and APCs.

The immune system has the capacity to detect tumor cells and employ a variety of biologicalmechanisms, or immune effector functions, to specifically target and destroy these cells. However, tumors are adept at undermining normal immune system functions allowing cancer cells to evade such detection and destruction.

The Tumor Microenvironment

Tumors can generate signals that promote tumor growth and suppress immune system functions. The TME is an immunosuppressiveenvironment that surrounds a tumor and includes blood vessels, immune cells, and signaling molecules. A significant portion of the immune reaction against tumors occurs within the TME. There is constant interplay between the TME and the tumoritself, as signals from the tumor can facilitate immunosuppression and tumor growth. In recent years, growing understanding of this interplay has led to the successful development of therapies that modulate specific immunosuppressive mechanismswithin the TME to activate the immune system against cancer cells.

Within the TME, several molecules have been identifiedthat play critical roles in regulating immune functions. These include:

 

  

PD-1/PD-L1: PD-1 and its ligand,PD-L1, are critical regulators of the immune system, known as immune checkpoints. The interactions between PD-1 with its ligandPD-L1 inhibit T cell effector functions against tumor cells. Tumor cells can upregulate PD-L1 to evade the attack of the immune system andPD-L1 expression is correlated with increased tumor aggressiveness and poor patient prognosis. PD-L1 expression has been reported for both hematological cancer and solidtumors;

 

  

IDO: IDO is a metabolic enzyme that regulates immune function through depletion of tryptophan, which isessential for T cell effector function, as well as production of immunosuppressive metabolites such as kynurenine. Such depletion of tryptophan and production of kynurenine is also known as canonical immune suppression. IDO also suppresses immunitythrough non-enzymic effects, known as non-canonical immunosuppression. IDO has been demonstrated to be a critical cellular factor contributing to the suppression of anti-cancer immunity. IDO is expressed in many solid tumors and hematologicalmalignancies and its activity has been shown to correlate with a poor prognosis and reduced survival; and

 

  

Arginase: Arginase 1 (arginase) is an enzyme that contributes to immune regulation by catabolizing andlimiting the availability of arginine, which is essential for immune effector cell survival and growth. Arginase overproduction by immunosuppressive cells such as MDSCs is a well-documented tumor escape mechanism. Arginase is highly expressed in difficult-to-treat cancers, including colorectal, breast, prostate, pancreatic and ovarian, and is associated with high levels of MDSCs.

These immune markers are often dysregulated and over-expressed in a widerange of cancers. The figure below shows the role of these molecules in immunosuppression within the TME:

Engaging the Immune System to Fight Cancer

In recent years, rapidly growing understanding of the interaction between cancer and the immune system, known asimmuno-oncology, has led to the development of a number of therapeutic approaches that aim to counter the tumor-driven immunosuppression in the TME, to allow the immune system to fight cancer. These approaches include:

 

  

Checkpoint Inhibitors: Checkpoint inhibitors include PD-1, PD-L1 Antibodies and CTLA-4 among others. PD-1 and PD-L1 antibodies block the immunoregulatory functions of PD-1 and PD-L1, respectively,allowing T cell-mediated immune responses against tumor cells. PD-1 and PD-L1 antibody therapies have shown significant clinical efficacy resulting in broad commercialsuccess. However, while such therapies are highly effective in certain subsets of patients with specific types of tumor, there are a significant number of cancer patients for whom these therapies are not effective;

 

  

IDO Inhibitors: IDO inhibitors aim to alleviate the immunosuppressive effects of the IDO protein byblocking one of its well-established biological functions, its enzymatic activity responsible for converting tryptophan (a desirable T cell metabolite) into kynurenine (a non-desirable T cell metabolite contributing to a hostile tumormicroenvironment). This is often referred to as the canonical immune suppressive function of IDO. However, there is also evidence demonstrating that the protein induces immune suppression of T-cells via a mechanism independent of tryptophanconversion, often referred to as the non-canonical immune suppressive functions of the IDO protein. Hence, blocking the immune suppressive activity of IDO will likely require blocking all its related functions. IDO inhibitors have shown clinicalpotential in combination with anti-PD1 antibodies in early-stage trials but have not been able to demonstrate the same level of efficacy in late-stage clinical trials.

Table of Contents
  

Peptide immunotherapies: These therapies are based on peptides which represent tumor antigens, piecesof a key protein, or surface markers on the cancer cell, and whose presentation to the adaptive immune system leads to a specific immunological response directed at that target. Their aim is to direct immune system effector functions, including CD8+ T cells, against antigens expressed on tumor cells. Although previous peptide immunotherapies have demonstrated attractive safety and tolerability profiles, they have only demonstrated modestclinical efficacy to date, likely reflecting (i) the ability of tumors to escape immune recognition by loss of antigens and (ii) the ability of tumors to orchestrate an immunosuppressive microenvironment. Collectively, these abilities arereferred to as tumor immune escape.

These immuno-oncology approaches have typically sought to blocksingle immunosuppressive pathways employed by tumors or to direct the immune system against antigens or neoantigens expressed by tumors cells. We believe that by directing the immune system against both tumor cells and other healthy cells within theTME that express immunosuppressive molecules such as PD-1 or IDO, we have the potential to drive significant benefits for patients by transforming the immune balance within the TME.

Our Approach: Targeting The TME With Our T-win Technology Platform

OurT-win platform is a novel approach to cancer immunotherapy designed to activate naturally occurring T cells to target immunosuppressive mechanisms. Our T-win productcandidates are designed to employ a dual mechanism of action: (1) direct killing of immunosuppressive cells, including both tumor cells and genetically stable cells in the TME, that express key immunosuppressive proteins such as IDO and PD-L1 and (2) modulation of the TME into a more pro-inflammatory, anti-tumor environment. This is in contrast to previous methods that have sought either to only blocksingular immunosuppressive pathways or to direct the immune system against specific identified antigens expressed by tumor cells. We believe that our dual mechanism approach has the potential to induce tumor regression, establishing lasting anddurable antitumor response, and to achieve manageable tolerability for patients.

T-win is based on the discovery of naturally occurring,pro-inflammatory T cells against immunosuppressive mechanisms mediated by key immunosuppressive proteins, such as IDO and PD-L1, that are present in the periphery andamong tumor-infiltrating lymphocytes of cancer patients and, to a lesser degree, in healthy individuals (Figure 2 below). When isolated and cultured in vitro, the self-reactive IDO- or PD-L1-specific T cells demonstrated proinflammatory and cytotoxic responses against IDO- or PD-L1-expressing target cells (Figure 3 below).

Key Components of Our T-win Technology Platform

Based on this discovery, we created our T-win technology platform to directthe immune system against cells, both tumor cells and genetically stable cells within the TME, that express immunosuppressive proteins, with the goal of transforming the immune balance within the TME.

The key elements of our T-win platform are:

 

  

Target selection: We select targets based on well-documented immunosuppressive proteins that are knownto be overexpressed in the TME across a wide range of tumors. Our target selection relies on the identification of T cell immunity against these key immune resistance pathways in the TME;

 

  

Epitope selection: After a target is selected, the ability of the immune system to attack cellsoverexpressing immunosuppressive molecules is confirmed by examination of intrinsic T cell immunity. The initial epitope selection process involves screening peptide antigens, which are designed using both an in silico algorithm and our know-how for T cell reactivity in peripheral blood mononuclear cells derived from cancer patients across several indications. Upon identification of an immunogenic peptide antigen, the functionality of reactive Tcells is then subjected to further testing to further evaluate whether activation leads to a favorable pro-inflammatory or anti-tumorigenic phenotype. Every T-winplatform product candidate is designed to contain both CD4+ and CD8+ T cell epitopes that can be recognized over a wide range of patientpopulation; and

 

  

Adjuvant: T-win peptide product candidates are administeredtogether with an adjuvant, such as Montanide. This provides protection to and facilitates effective release of our T-win peptide product candidates upon injection. It also causes local inflammation andfacilitates recruitment of immune cells. This enables the antigen to be captured by antigen presenting cells and presented to T cells to drive their activation.

T-win Mechanism of Action

Our product candidates are designed to drive to activation and expansion of T cells reactive to immunosuppressiveantigens. Upon trafficking of these T cells into the tumor site, effective anti-tumor response is induced by a dual mode of action:

 

  

Recognition and elimination of tumor cells; and

 

  

Recognition and elimination of immunosuppressive cells.

We believe T-win offers a novel approach that targets both tumor cells as well as genetically stable host immunosuppressivecells, in order to avoid immune escape. By attracting pro-inflammatory cells against immunosuppression within the TME, T-win product candidates are designed to alter the immunologically unfavorable TME environment into a pro-inflammatory milieu,thereby enhancing effective anti-tumor T cell responses. We believe that our T-win technology is the only existing platform that utilizes the intrinsic ability of cancer patients’ own T cells to target immunosuppression in the TME.

Administration of our T-win product candidates (Figure 4, step 1) selectivelyactivates and expands pre-existing CD4+ and CD8+ T cell responses against the T-win product candidate targeted antigen, such as those derived from IDO, in the draining lymph nodes (step 2). The resulting T cells migrate to the tumor sites, where target cells with elevated expression of T-win product candidate targeted antigens are found in the TME. Upon recognition and engagement of the targeted cells, the T cells either directly eliminate the cells by cytotoxic lysis or respond by the release ofproinflammatory cytokines (step 3). Elimination of immunosuppressive target cells and concomitant immune modulation of the TME into an inflamed environment results in net enhancement of T effector infiltration and enhanced anti-tumor responses (step4).

Advantages of the T-win Technology Platform

We believe ourT-win platform has the potential to pave the way for novel therapies with increased therapeutic effect and limited additional tolerability concerns. Potential advantages of ourT-win platform include:

 

  

Durability of response. T-win product candidates are designedto target not only tumor cells but also genetically stable healthy immunosuppressive cells, with the aim of avoiding immune escape. We believe that our approach of direct and indirect target killing may lead to immune memory, and thus sustainedanti-tumor effect over time;

 

  

Dual and Multi-Epitope Design. In our product candidates, we often seek to include dual or multipleepitopes. The rationale behind this approach is based on the complexity of cancer, where individual patients suffering from the same cancer indication may have a different expression of immunoregulatory antigens and as a result may not respond to asingle epitope treatment. We believe that an approach of targeting separate immune resistant pathways in the TME will enable our product candidates to address a larger pool of patients than currently available therapies;

 

  

Tolerability. Therapies based on subcutaneously injected peptides have been observed to bewell-tolerated in over 200 clinical trials. If T-win product candidates based on subcutaneously injected peptides are similarly well-tolerated, our product candidates could have the potential to be used as acomponent of combination therapy in early treatment settings;

 

  

Versatility. Our product candidates based on our T-win platformhave the potential to be used in combination with existing therapies such as checkpoint inhibitors, including the PD-1 monoclonal antibodies, pembrolizumab and nivolumab. As our product candidates target arange of immunosuppressive mechanisms mediated by proteins highly expressed among several cancer indications and the mechanism of action can potentially provide supplementary effect across different checkpoint inhibitors, we believe that the numberof cancer indications and combination opportunities of our product candidates are extensive;

 

  

Well-understood manufacturing process. The compounds necessary for the production of product candidatesbased on T-win technology are manufactured through well-known synthetic chemistry process. We believe this enables us to reproduce high quality product at an anticipated low cost of goods; and

 

  

Ease of administration. T-win product candidates are designedto be “off-the-shelf” treatments given subcutaneously on a flexible treatment schedule. These treatments can be adapted for specific cancer indications.

Our Product Candidates

We are developing a pipeline of product candidates that leverage our T-win technology platform to address targets within theTME. In addition to a potentially registrational Phase 3 trial in melanoma, we are planning two Phase 2 basket trials in additional solid tumors and treatment settings. We are also developing earlier stage product candidates that targetadditional immunosuppression-related targets that are expressed in a broad range of solid tumors. We expect to use these earlier stage product candidates in combination with our existing pipeline candidates.

Dual Epitope IO102-IO103

Our lead product candidate, IO102-IO103, combines our two fully-owned, novel immunotherapeutics, IO102 and IO103, which aredesigned to target IDO and PD-L1 expressing cells, respectively. IDO and PD-L1 are often dysregulated and over-expressed in a wide range of solid tumors, and result inthe inhibition of the body’s natural pro-inflammatory anti-tumor response within the TME. By combining IO102 and IO103 in a single treatment regimen, we aim to provide a synergistic effect on tumors. Weare currently planning a Phase 3 potentially registrational trial in advanced melanoma for IO102-IO103, the IOB-013/KN-D18 trial, in combination with pembrolizumab.

IO102 contains a single IDO-derived peptide sequence and is designed to engage andactivate IDO-specific T cells against IDO expressing cells within the TME. This contrasts to small molecule IDO inhibitors that aim to address tumors by inhibiting IDO pathways. IO103 contains a single PD-L1-derived peptide and is designed to engage and activate PD-L1 specific human T cells againstPD-L1 expressing cells. This is in contrast to PD-1/PD-L1 antibodies which aim to counter T cell inhibition by blocking the interaction between PD-1 and its ligand. Through the activation of both IDO and PD-L1 activated T cells, IO102-IO103 is designed to directly kill immunosuppressive cells, including both tumor cells and genetically stable cells within the TME, and to reduce immunosuppression within the TME, inorder to confer clinically meaningful and long lasting anti-tumor responses.

The following graphic illustrates the distinct approaches by which our T-winproduct candidates engage with IDO expressing cells versus other clinically tested IDO inhibitors.

On December 14, 2020, the FDA granted us BTD for IO102-IO103 in combination withpembrolizumab for the treatment of patients with unresectable or metastatic melanoma based on data from the MM1636 Phase 1/2 clinical trial. BTD enables us to solicit guidance from the FDA on generating the clinical evidence needed to supportapproval in a potentially expedited manner. The MM1636 trial is an investigator initiated, single-arm Phase 1/2 trial of 30 anti PD-1/PD-L1 naïve patients with metastatic melanoma receiving IO102- IO103 and nivolumab, an anti-PD-1 monoclonalantibody. In this trial, investigators initially observed an ORR of 80% (24 out of 30 patients); however, two of 24 patients in which a response was observed progressed before subsequent radiological confirmation, which resulted in a confirmed ORRof 73%. In addition, 47% of patients achieved a CR, or complete elimination of their tumors based on RECIST 1.1 definitions. Based on the 17% discontinuation rate of treatment with both nivolumab and IO102-IO103, we believe that the data from thistrial suggests a manageable tolerability profile for patients. In addition, we have observed treatment-induced infiltration of CD3/CD8 T cells into the tumor site in responding patients and detected IO102+IO103-specific T cells in tumors aftertreatment in correlative biomarker data where this was analyzed. We are currently planning a Phase 3 potentially registrational trial for IO102-IO103, the IOB-013/KN-D18 trial, in combination with pembrolizumab, which we expect to initiate by theend of 2021. The Phase 3 trial will include a safety run in.

IO102-IO103 specific T cells were found in the peripheralblood mononuclear cells (PBMCs) and at the tumor site.

Preclinical Development

We developed IO102 and IO103 to target two separate immune resistant pathways involving IDO andPD-L1, respectively. Key learnings from our preclinical development of these candidates include:

 

  

IO102 and IO103-targeted human T cells isolated from cancer patients have demonstrated proinflammatory andcytotoxic functions against IDO+ and PD-L1+ target cells in vitro, respectively;

 

  

Both IO102 and IO103 have demonstrated anti-tumor activities as monotherapy and controlled tumor growth inpreclinical models where IDO and PD-L1 respectively are expressed in the TME;

 

  

The combination of IO102 and 1O103 (dual epitope IO102-IO103) demonstrated additive anti-tumor activitybetween IO102 and IO103 treatment in a murine tumor model; and

 

  

There have been no health impairments in the two non-clinical toxicitystudies performed with the combination of IO102 and IO103 (dual epitope IO102-IO103).

IO102-IO103 isdesigned to target and expand intrinsic T cells found in cancer patients that are capable of directing the immune attack against IDO+ and PD-L1+ target cells. Such intrinsic immunity against IDO and PD-L1 has also been observed in mice, and an immunotherapeutic approach using murine IO102 (mIO102) and murine IO103 (mIO103) showed promising anti-tumor activities. Because the expression of IDO and PD-L1 inmelanoma patients has been reported in distinct cell populations in the TME, the anti-tumor activity of co-administration of mIO102 and mIO103 was tested in a syngeneic model (Figure 5 below). The combination of mIO102 and mIO103 treatments resultedin enhanced control of tumor growth in an additive fashion.

Figure 5: Anti-tumor Activity ofCo-administration of mIO102 and mIO103

Treatment with either mIO102 (IDO) or mIO103(PD-L1) alone reduced the tumor growth rate. When combined together, it further improved this anti-tumor activity in CT26 model. Mice were treated once with mIO102 and/or mIO103 peptides once, 7 days and 13days after tumor inoculation in a syngeneic model.

Melanoma

IO102-IO103 is currently being tested in the MM1636 trial in both treatment-naïve(cohort A) and PD-1/PD-L1 mAb refractory (cohorts B and C) patients with metastatic melanoma. Unresectable, metastatic melanoma is a serious and life-threatening diseasewith a clear unmet medical need. In the United States, it is expected that approximately 106,000 patients will be diagnosed with, and about 7,200 people will die from, melanoma in 2021. The incidence of cutaneous melanoma is increasing, and advancedmelanoma (unresectable or metastatic) is fatal if left untreated. According to Ascierto (JAMA Oncology 2019), Robert (New England Journal of Medicine 2019), and Larkin (New England Journal of Medicine 2019), the median OS in patients with

 

112


Table of Contents

stage IV melanoma (untreated) regardless of BRAF mutation status is between 37-39 months and five-year OS is approximately40-50%. Anti-PD-1 monotherapy leads to a five-year OS of approximately 43-51%, while anti-CTLA-4 and anti-PD-1 combination therapy can increase five-year OS to approximately 52%, but is associated withconsiderable toxicity. Accordingly, there is a clear unmet need for improved combination therapies with the potential to enhance anti-PD-1 efficacy without a significantincrease in toxicity.

Historical and Current Standard of Care

Historically, chemotherapy, with or without interferon-alpha (IFN-a) or IL-2, was offered to patients with advanced melanoma, with limited results. Although in the last decade, the treatment of advanced melanoma has improved with the approval of many novel agents, the current standardof care does not work for many patients. Before the availability of these treatments, according to Maio (Journal of Clinical Oncology 2015) and Garbe (The Oncologist 2011), patients with advanced melanoma had a median survival time of approximately10 months. According to Robert (New England Journal of Medicine 2019) and Larkin (New England Journal of Medicine 2019), the current long-term survival is at least 37 – 39 months for patients with advanced melanoma regardless of BRAF mutationalstatus based on current standard of care.

The currently approved novel agents can be divided into two main categories:

 

  

Immunotherapies – Immune checkpoint inhibitors (CIs) targeting CTLA-4, such as ipilimumab, and PD-1, such as nivolumab and pembrolizumab, indirectly activate the immune system. The immune system plays an important role in theregulation of melanoma and intravenously administered immunotherapies help overcome immune suppression; and

 

  

Targeted agents – Orally administered selective inhibitors of mitogen-activated proteinkinase (MAPK) directly inhibit the oncogene BRAF and MAPK pathway. According to Drummer (Lancet 2018), around 35-50% of advanced melanoma patients have a targetable BRAF mutation, and in approximately 90% ofthese cases, the mutation consists of valine substituted with glutamic acid at amino acid 600 (BRAF V600).

Recommended first-line treatment options for the treatment of unresectable or metastatic melanoma and for patients with orwithout BRAF-mutant advanced melanoma are summarized below:

 

  

Anti-PD-1 monotherapy (nivolumab or pembrolizumab);

 

  

Anti-CTLA-4 (ipilimumab) and anti-PD-1 (nivolumab) combination therapy;

 

  

Dabrafenib/trametinib combination targeted therapy if the activating BRAF-V600 mutation is present; and

 

  

Vemurafenib/cobimetinib + atezolizumab combination targeted therapy and immunotherapy if the activatingBRAF-V600 mutation is present.

For patients with tumors harboring a BRAF V600 mutation, treatment choices are between MAPK or CI therapy. Cross trialcomparisons indicate that combined MAPK or BRAF plus mitogen-activated protein kinase kinase (MEK) has proven to have higher response rates than CIs. Data from cross trial comparisons suggest that the responses to CIs are slower in onset but moredurable. For patients who are candidates for both treatments, standard of care guidelines recommend that CIs should be chosen as first-line therapy. Patients whose tumors are not progressing quickly and are not immediately threatening an importantorgan function, should be considered for CIs first, preserving MAPK for subsequent lines. However, American Society of Clinical Oncology guidelines do not recommend a specific order of therapies for patients with BRAF wild-type (WT) unresectable andmetastatic cutaneous melanoma.

As combination therapy with ipilimumab/nivolumab is associated with more severe toxicity,physicians must make a treatment decision between combination therapy and single agent anti-PD-1 antibody therapy after thorough evaluation regarding clinical activityand potential severe toxicity. Accordingly, we believe novel anti-PD-1 combinations with improved overall outcomes are needed for patients with advanced melanoma.

We are developing IO102-IO103 for potential treatment of patients with anti PD-1naïve in the advanced setting advanced melanoma who are candidates for CI monotherapy, regardless of PD-L1 expression and BRAF mutation status, except for patients with rapidly progressing disease. Wealso plan to test IO102-IO103 as a neo-adjuvant used before surgery, followed by adjuvant therapy after surgery, in patients with melanoma, in a basket trial, the IOB-032 trial, with multiple solid tumor indications.

Development of Dual Epitope IO102-IO103 in the First-line Setting

Summary

The MM1636 trial is currently evaluating IO102-IO103 in combination with an anti-PD-1 monoclonal antibody, nivolumab, in 30 anti-PD-1 naïve, first-line metastatic melanoma patients. A brief summaryof the MM1636 trial is below:

 

  

30 patients included in cohort A from the Copenhagen University Hospital Herlev Denmark;

 

  

Baseline characteristics were largely comparable with benchmark trials with the majority of patients havingone or more poor prognostic factors, such as negative tumor expression, M1c stage/visceral metastases and high lactate dehydrogenase (LDH);

 

114


Table of Contents
  

Investigators initially observed an ORR of 80% (24 out of 30 patients); however, two of 24 patients in which aresponse was observed progressed before subsequent radiological confirmation, which resulted in a confirmed ORR of 73%. CRR was 47% with duration of response not yet reached at a median follow up time of 27.3 months as of February 22, 2021;

 

  

Median PFS was 26 months and median OS had not yet been reached as of February 22, 2021;

 

  

Correlative biomarker data from the MM1636 trial support the mechanism of action of IO102-IO103 in treatedpatients, based on the following observations:

 

  

Induction of systemic therapy (IO102+IO103)-specific T cell response in blood;

 

  

Treatment-induced increased infiltration of CD3/CD8 T cells into the tumor site with enhanced immune effectorsignature in responding patients;

 

  

Detection of IO102+IO103-specific T cells in tumors post treatment; and

 

  

Ongoing enrollments of 10 patients each in cohort B (patients with anti-PD-1 de-novo refractory disease) andcohort C (patients with acquired anti-PD-1 resistance, meaning those who progressed after anti-PD-1 therapy).

MM1636Trial Design and Patient Characteristics

The MM1636 trial is a Phase 1/2 single arm, single center trial with theprimary objective to investigate safety and feasibility, secondary objective to investigate immunogenicity and tertiary objective to investigate clinical efficacy. While the size of the trial was deemed sufficient to evaluate safety, as a single armtrial, the MM1636 trial was not designed to provide statistically significant results in respect of its clinical efficacy endpoints. The MM1636 trial patients were treated with IO102-IO103 in combination with nivolumab for up to 47 weeks andthereafter continued with nivolumab treatment according to usual guidelines. Treatment consisted of 100 µg IDO long, 100 µg PD-L1 long1, 25 µl dimethyl sulfoxide (DMSO), 475 µl phosphate-buffered saline (PBS) and 500 µlMontanide. The treatment was administered biweekly for 6 weeks and then every 4 weeks for 41 weeks. Patients were given a maximum of 15 treatments during one year or until progression or undue adverse events. Nivolumab was administered according tothe approved label for melanoma (3 mg/kg bi-weekly for up to two years). Because of the preclinical data on IO102-IO103, which provided support for the combination effect of our IDO and PD-L1 targetedcandidates, IO102 and IO103, the MM1636 trial was not designed to evaluate the individual contributions of each component antigen.

A review of patient baseline characteristics presented in table 2 for the 30 anti PD-1naïve metastatic melanoma patients included in the MM1636 trial shows that the majority of patients had one or more poor prognostic factors; 43% PD-L1 negative, 60% visceral metastatic disease (M1c) and37% high LDH. The frequency of these poor prognostic factors indicates that the patient population was not subject to specific selection of good prognosis patients, as the baseline characteristics are largely similar to those in other trials.

Tolerability

In the MM1636 trial, 77% of patients developed Common Terminology Criteria for Adverse Events (CTCAE) grade 1 and 2injection site reactions that typically manifested as transient adverse events; 77% injection site tenderness, 63% granulomas, 23% redness, 13% pain, 13% pruritus, and 3% myalgia at the injection site, most likely related to the adjuvant Montanide.Two patients discontinued treatment after eight and 11 injections, respectively, due to granulomas, tenderness and pain that limited instrumental activities of daily living. Other CTCAE grade 1-2 AEs haveincluded rash (50%), fatigue (47%), arthralgia (37%), diarrhea (27%), nausea (23%), amylase increase (20%), dry skin (20%), pruritus (20%), infusion reaction (17%), xerostomia (17%) and myalgia (17%).

A total of five patients (17%) have experienced a high-grade adverse event (grade3-5); four patients (13%) experienced CTCAE grade 3-4 AEs, one patient with grade 3 maculopapular rash, one patient with grade 3 adrenal insufficiency and twopatients with grade 3 arthralgia. One patient died (CTCAE grade 5) due to urosepsis with multi organ failure and severe hyponatremia. In addition, the patient had experienced multiple AEs including grade 3 colitis, grade 2 pneumonitis, grade 3arthralgia, grade 2 vasculitis and grade 2 nivolumab induced infusion allergic reaction. The patient had symptoms of myocarditis at time of death with highly elevated troponin I. Bedside echocardiography showed an ejection fraction of 15%,which at baseline was 60%. The myocarditis was never confirmed pathologically. All the AEs leading to treatment discontinuation were considered by the investigator to be related to nivolumab. The rate of treatment-related adverse events leading todiscontinuation of both nivolumab and IO102-IO103 was 17%.

Response Rate

Results from the MM1636 trial, with a cut-off date of February 22, 2021, showed anORR of 80% (95% confidence interval (CI); 62.7-90.5%). Two of the 24 responding patients progressed before subsequent radiological confirmation, therefore the confirmed ORR was 73.3% (95% CI; 54.1% to 87.7%).The CRR was 46.7% (95% CI; 28.3% to 65.7%).

Comparison With Contemporary anti PD-1 TreatedPatients from the National Danish Metastatic Melanoma Database (DAMMED)

To address potential trial bias regardingtreatment effect through post-hoc exploratory analysis, patients in the MM1636 trial were matched with patients from the Danish Melanoma Database (DAMMED), which is a population-based database that retrospectively collects data on patients withmetastatic melanoma in Denmark.

 

  

938 patients who were treated with a PD-1 therapy monotherapycontemporaneously (January 2015 to October 2019) were extracted. 218 of these patients were eligible for comparison and matching (all parameters available). 60 DAMMED patients were found to match;

 

  

Patients were matched on age (£70, > 70), gender, LDH (normal,elevated), M-stage (M1a, M1b, M1c), BRAF status (Wildtype, mutated) and PD-L1 status (<1, ³ 1). An exact matchingalgorithm was used where patients in the MM1636 trial were matched with patients from DAMMED with exact same combination of variables;

 

  

29 patients from the MM1636 trial were matched with the exact combinations of the six variables. One patientcould not be matched. To secure balance of the calculations, control patients were weighted according to the number of patients for each MM1636 patient. Estimates for treatment effects were calculated by weighted logistic regression analyses andweighted Cox proportional hazard model. A weighted binary logistic regression model was used for comparing response rates in the two matched cohorts; and

 

  

Matched controls were identified for 29 patients and the ORR of 79.3% (95 CI:61.0-90.4%) observed in the MM1636 trial was found to be significantly higher (p<0.0012) compared to the matched control group where an ORR of 41.7% (95% CI:31.0-53.3%) was reached. Furthermore, of the 29 patients in the MM1636 trial, a significantly (p<0.0017) higher percentage of 41.4% (CI: 25.2-59.6%) patients achievedCR in the MM1636 trial, compared to 12% (CI: 6.3-21.6%) in the matched historical control group.

Table of Contents

The ORR was significantly higher in the patients from the MM1636 trial thanin the historical controls, suggesting that the high response rate and the long durability of response observed with the combination therapy approach are unlikely to be due to patient selection bias.

Tumor Shrinkage in Individual Patients

Data showing the percent change in target lesions from the baseline is shown in Figure 6. The effect was binary, as patientseither responded (24 out of 30) or progressed (six out of 30). No patients showed stable disease (SD). The icons describe melanoma risk factors. Green bars indicating CR that are not at 100% tumor reduction are in patients with lymph nodemetastases, as lymph nodes do not disappear but normalize in size. Blue bars at 100% indicate the disappearance of target lesions, whereas some non-target lesions may remain based on RECIST 1.1. definitions.Six of the 30 patients progressed (red bars).

Timing and Durability of Response in Individual Patients

The swimmer plot in Figure 7 presents individual patient-level data, including onset of PR, CR, PD and death. In addition,patients with ongoing responses are marked with an arrow. The majority of patients achieving a CR had one or more high risk factors (marked with icons) such as PD-L1 negative tumor expression, M1cstage/visceral metastases and high LDH as an indication severe disease. As of the February 22, 2021 cut-off date, response was still ongoing in 16 patients (indicated with arrows).

Because CRs have been observed as late as 15 months after initial treatment, the CRR may improve beyond 47% as the latestincluded patients had follow up time shorter than 15 months as of the February 22, 2021 cut-off date. We believe these data indicate good quality responses with a deep and durable response in most of thepatients (Figure 8).

The median duration of response (DOR) had not yet been reached as of the February 22, 2021 cut-off date in the MM1636 trial, but 20 of the 22 patients with a radiologically confirmed response (at 12 weeks after the first response) had a response lasting greater than 182 days providing a durable responserate of 66.7% (20/30). (Figure 7 and 9).

Potential Opportunities for Dual Epitope IO102-IO103

Proposed Registrational Trial in Melanoma Under BTD by FDA

Based on the results of the MM1636 trial to date, we plan to initiate a multicenter, international, open-label, randomized,two-arm Phase 3 potentially registrational trial of IO102-IO103, the IOB-013/KN-D18 trial, in combination with pembrolizumab as first-line treatment for patients with previously untreated unresectable or metastatic (advanced) melanoma. ThePhase 3 trial has a target enrollment of 300 patients randomized into either the experimental arm of IO102-IO103 in combination with pembrolizumab or the pembrolizumab control arm. All patients will receive pembrolizumab 200 mg intravenously everythree weeks for a maximum of 35 cycles, corresponding to approximately two years of treatment. Patients randomized to the control arm will also be given IO102-IO103 every three weeks with an additional dose given during the induction period onDay 8 of cycles 1 and 2. IO102-IO103 will thereafter be administered subcutaneously every three weeks during the maintenance

period. Each patient can be treated for a maximum of 37 administrations in total, corresponding to approximately two years of treatment. An interim analysis of ORR will be conducted by the end of2023. The primary endpoint at the final analysis will be progression free survival. The trial design and discussions with FDA are aimed at potentially pursuing accelerated approval, if the trial data are favorable, based on the interim analysis ofORR, supported by data on durable response rate, complete response rate and a descriptive summary of progression free survival. The Phase 3 trial will include a concurrent evaluation of the initial participants to allow for an assessment of safety,or safety run in. We anticipate initiating the trial by the end of 2021.

Lung Cancer

Lung cancer is the leading cause of cancer death according to the American Cancer Society (ACS). The two main types of lungcancer are NSCLC and small cell lung cancer. NSCLC is the most common type of lung cancer, accounting for about 84% of all cases. According to the ACS, the five-year survival rate for patients suffering from highly advanced, metastatic (Stage IV)lung cancers is estimated to be 6%. The NSCLC market is expected to generate $28.5 billion in revenue in 2021, growing to $48 billion in 2026.

There is a large unmet need for improved combination therapies enhancing anti-PD-1efficacy without a significant increase in toxicity. Until recently, the standard of care for patients with metastatic NSCLC was platinum-based chemotherapy. Recently,anti-PD-1 therapy, such as pembrolizumab, with or without chemotherapy, has changed the standard practice in first-line treatment of metastatic NSCLC. According to Mok(Lancet 2019) and Gandhi (New England Journal of Medicine 2018) the ORR with pembrolizumab monotherapy in patients with previously untreated metastatic NSCLC and a PD-L1 expression of 50% or higher was 39% andpembrolizumab in combination with chemotherapy 61%. In high PD-L1, approximately 40% of patients are alive after 30 months on pembrolizumab monotherapy. In low PD-L1,approximately 45% of patients are alive at 24 months on pembrolizumab plus chemotherapy.

Observations from a Phase 1trial of our first generation IDO compound, IO101, provided us foundational support for our IO102-IO103 development strategy. We are planning development of IO102-IO103 plus anti PD-1 in first-line treatmentof metastatic solid tumors with high PD-L1 expression. NSCLC is one of the indications in our basket trial.

First Generation IDO Compound

LU1006 was an investigator initiated Phase 1 single arm, first in human trial with the primary objective to investigate safetyand secondary objective to investigate immunogenicity and tertiary objective to investigate clinical benefit in patients with heavily pretreated human leukocyte antigen-A2 (HLAA2) positive stage III to IV NSCLC. Patients had stable diseaseafter standard therapy comprising of chemotherapy and targeted therapy. The trial was a non-randomized comparison against patients who had standard of care, chemotherapy, at the site and were HLAA2 negative.15 patients were treated with IO101 as subcutaneous injections formulated in 900 microliters Montanide and imiquimod ointment. The mean treatment duration was 7.9 months (95% CI: 4.6 –11.3).

Tolerability

In 90% of the patients, CTCAE grade 1 to 2, short-term, local injection site reactions (i.e., redness, swelling, or itching)were observed. Local treatments with steroid ointments removed the symptoms. High frequencies of fatigue, shortness of breath, coughing and haemoptysis were present at baseline in the 15 NSCLC patients. These were considered probably related to theunderlying lung cancer. Nausea and headache were observed in relation to the development of brain metastases, whereas dyspepsia, abdominal pain and diarrhea could be related to the treatment, as IDO is expressed in the epithelial cells in thegastrointestinal tract (Table 5). No grade 3 or higher AEs were observed in the 15 patients treated with IO101 monotherapy.

Clinical Benefit

Clinical benefit was defined as OR or SD for a minimum of 8.5 months after treatment initiation, corresponding to at least nineinjections and demonstration of SD on at least three consecutive CT scans. Based on this definition, seven of 15 (47%) patients had clinical benefit. One patient achieved a PR after 15 months treatment (ORR of 7%), and six patients obtained SD(40%).

Survival

PFS is provided in Figure 15 below, “censored” represents patients who are surviving without progression of disease.The median PFS was 5.2 months. Overall survival was 26 months in the 15 patients treated with IO101, compared to eight months in patients who received the hospitals standard of care, which included chemotherapy and targeted therapies. Theseobservations provided us foundational support for our IO102-IO103 development strategy.

Long Term Follow-Up

According to Kjeldsen (2018), three of 15 patients were still alive at a five-year follow up corresponding to a six-year overall survival of 20%. Two patients had continued monthly injections for five years (56 injections). One of these patients developed a PR 15 months after the first injection and remained in PR, withoutother subsequent anti-cancer therapy.

The other patient had a solitary distant metastasis in a retroperitoneallymph node at baseline which normalized during treatment. All on study CT scans were without signs of relapse. Treatment was well tolerated for up to five years with no long-term AEs registered. The third long-term surviving patient discontinuedtreatment after 11 months due to PD.

Second Generation IDO Compound (IO102)

Our second generation IDO compound, IO102, is currently being tested in an ongoing, fully recruited, open-label, randomizedPhase 1/2 trial in combination with pembrolizumab (Cohort A) or pembrolizumab with chemotherapy (Cohort B) as first-line treatment for patients with metastatic NSCLC. The trial has a Phase 1 safety run in and Phase 2 is randomized (Figure 18). Theprimary objectives are to investigate the safety and efficacy of IO102 as add on to standard of care versus standard of care. Primary endpoints are safety and ORR. Secondary endpoints include OS, PFS and biomarkers.

The trial is being conducted as part of a clinical collaboration with Merck.The clinical trial is sponsored by IO Biotech while Merck provides pembrolizumab for the trial. Merck and IO Biotech have joint rights to the study results. IO Biotech will maintain global commercial rights to IO102.

Results presented below are from an updated analysis of patients entered into the Phase 2 part of the study, with a datacutoff of August 11, 2021. At this data cut off, a total of 110 patients were included in the trial, of which 109 received treatment. Six patients each in Phase 1 cohort A and B; 32 patients in the experimental arm A1 (IO102 with pembrolizumab), 16patients in the control arm A2 (pembrolizumab); 33 in the experimental arm B1 (IO102 with pembrolizumab and chemotherapy) and 17 in the control arm B2 (pembrolizumab with chemotherapy) of which 16 were treated.

At the data cutoff, based on RECIST 1.1 definition, Phase 2 Cohort A patients in the experimental arm achieved ORR of 46.9%and 43.8% in the control arm. In Phase 2 Cohort B, patients in the experimental arm achieved ORR of 36.4% and 52.9% in the control arm.

In the NSCLC portion of the IOB-022 trial, we plan to investigate IO102-IO103 in patients expressing PD-L1 ³50%.

Table 6 summarizes the AEs reported as of the more recent data cutoff in August 2021.

All patients (100%), regardless of treatment allocation, had at least one treatment emergent adverse event (TEAE).

Cohort A (PD-L1³50%): 81% of patients in the experimental arm (A1) and 81% administered pembrolizumab (A2) had at least one treatment related AE. 69% of patients in A1 had AEs related toIO102. The corresponding number for treatment related AEs to pembrolizumab were 79% across both arms. Serious AEs (SAE) were reported in 41% and 31% of the patients and related treatment-related SAEs in 9% and 0%, respectively. High grade AEs (CTCAEgrade 3-4) were reported in 53% and 63% of patients, with 6% and 13%, respectively of the patients discontinuing any of the treatment due to TEAEs. Fatal (grade 5) AEs occurred in 3% and 6%, respectively.

Cohort B (PD-L1 <50%): 97% of patients in theexperimental arm (B1) and 100% administered pembrolizumab and chemotherapy (B2) had at least one treatment related AE. 67% of patients in B1 had AEs related to IO102. The corresponding number for treatment related AEs to pembrolizumab and were 82%across both arms. Serious AEs (SAE) were reported in 42% and 56% of the patients and related SAEs in 18% and 31%. High grade AEs (CTCAE grade 3-4) were reported in 73% and 94% with 33% and 19%, respectively,of the patients discontinuing any of the treatments due to TEAEs. Fatal (grade 5) AEs occurred in 9% and 0%, respectively.

The distribution of high-grade AEs (CTCAE grade 3 or higher, including fatal) is shown below.

Cohort A (PD-L1³50%): The most frequent high-grade AEs in cohort A1 (experimental, N=32), were infections, 18.8%, followed by vascular disorders, 15.6%. In A2 (control, N=16) the mostcommon high grade AE was infections and infestations reported in 25.0% of patients.

Cohort B (PD-L1 <50%): The most frequent high-grade AEs in cohort B1 (experimental, N=33), were blood and lymphatic system disorders, in 39.4% of patients with 62.5% in B2 (control, N=16).

When comparing the experimental treatment in Cohort A and B with the control treatment, the safety data appears largelycomparable, which suggests there was no increased frequency or severity of adverse events compared with the control arm.

Squamous Cell Carcinoma of the Head and Neck Cancer (SCCHN)

SCCHN includes cancers of the oral cavity, oropharynx, hypopharynx and larynx, and is one of the most common tumor typesworldwide. In the United States, cancers of the oral cavity, oropharynx, hypopharynx and larynx are expected to occur in more than 66,600 patients and more than 14,600 are expected to die. Locoregional SCCHN is treated with curative intent, but at acost of functional impairment and locoregional recurrence or metastatic disease.

Standard first-line treatment forrecurrent or metastatic (R/M) disease that is not amenable to local therapy was for more than a decade, cetuximab, an anti-epidermal growth factor receptor (EGFR) antibody, plus chemotherapy with

platinum and 5-fluorouracil (the EXTREME regimen), which provides a mOS of about 10 months and is associated with substantial adverse events, according toVermorken (New England Journal of Medicine 2008).

According to Burtness (Lancet 2019), in the KN-048 Phase 3 clinical trial, mOS with pembrolizumab was 12.3 months in patients with combined positive score (CPS) > 1% and 14.9 months in CPS > 20% versus 10.7 and 10.3 months with the EXTREME regimen. Inthe overall population, the mOS with pembrolizumab plus chemotherapy was 12.3 versus 10.7 months with EXTREME. Based on above pembrolizumab plus platinum and 5-fluorouracil is an appropriate first-linetreatment for R/M SCCHN and pembrolizumab monotherapy is an appropriate first-line treatment for PD-L1-positive recurrent or metastatic SCCHN. Pembrolizumab with orwithout chemotherapy did not improve the ORR versus EXTREME. ORR ranged from 17 to 23% with pembrolizumab versus 35-36% with EXTREME, pending on the CPS.

A significant number of cancer patients fail to respond to immunomodulatory agents regardless of PD-L1 expression, presumably because of tumor resistance mechanisms against immune attacks. According to Burtness (Lancet 2019), the two year OS in first-line R/M SCCHN ranged from 38% to 27%, pending on the CPS.Consequently, there is a large unmet need for improved combination therapies enhancing anti-PD1 efficacy without an increase in toxicity.

Besides anti-PD-1, investigations into theimmune landscape of SCCHN provide a strong rationale to test agents targeting other immunomodulatory pathways such as IDO and arginase, either as monotherapy or in combination with other therapies.

The head and neck cancer market is expected to generate $3 billion in revenue in 2021 and is expected to grow to$5.8 billion by 2026.

 

  

We are planning another development track in curative settings withneo-adjuvant (before surgery or radiotherapy)/adjuvant treatment (after surgery or radiotherapy). SCCHN may be one of these indications.

 

  

We are also considering investigating the dual epitope strategy in first-line setting of previously untreatedsolid tumors. R/M SCCHN may be one of these indications.

The ongoing and planned investigator-initiatedtrials will provide learnings that we can use in our own development of IO102-IO103, including in our planned first-line basket trial. See “—Additional trials in other first-line indications andneo-adjuvant and adjuvant settings” for additional details on these trials.

Developmentof Dual Epitope IO102-IO103 in Neo-Adjuvant/Adjuvant Settings

One ongoinginvestigator-initiated trial at the St Luc Hospital in Belgium (HN1901) is testing the effect of single epitopes (IO102 and IO103) and later dual epitopes (e.g. IO102-IO103) as neo-adjuvant therapy(before surgery) on the TME in a randomized Phase 2 Umbrella trial in patients with resectable SCCHN. Treatment is short term with up to 3-4 weekly injections and patients are randomized against no treatment(observation before surgery as standard of care).

The primary objective is to evaluate T cell epitope specificresponse in blood after injections and the secondary objectives include safety, tolerability and anti-tumor effects of the epitopes tested. Translational Research will also be investigated (see Table 10 below). As of an August 2021 data cutoff,seven patients were enrolled in the HN1901 trial – four in the IO102 single epitope treatment arm and three patients in the control arm (where no treatment prior to surgery is received). Among the four IO102-treated patients, one had twoprimary tumors, and two tumors changed from an intermediate to a high immunoscore, a measure of how well a body’s immune cells surround and enter a tumor, two tumors remained unchanged, and one tumor had a reduced immunoscore. In the controlarm, two patients maintained a stable immunoscore and one patient went from a high to intermediate immunoscore. In the IO102 treatment arm, only CTCAE grade 1-related adverse events were recorded. No serious adverse events related to the study drugwere reported. No delays in standard

treatment due to side effects were observed. Among the IO102-treated patients, diffusion imaging analysis showed a decrease in the median apparent diffusion coefficient (mADC) aftertreatment in patients ID05 (-11%) and ID06 (-14%) but not in patient ID01. One evaluable patient in the control arm (ID07) did not show changes in mADC.

Another investigator-initiated trial in SCCHN is planned at an academic site in the U.S. This trial will investigate dualepitope (IO102-IO103) therapy in combination with anti PD-1 as neo-adjuvant therapy before surgery followed by adjuvant therapy after surgery in patients with SCCHN.

Bladder Cancer

UBC is a common malignancy, and is expected to occur in almost 84,000 patients in the United States in 2021. It is expected toaccount for approximately 17,200 deaths in 2021. In the vast majority of patients, tumors are of the transitional cell subtype. Similar to other malignancies, UBC has a high rate of survival if diagnosed early (>90%); however, even regionalspread results in a decline in the five-year survival rate to under 50%. Approximately 75% of newly diagnosed cases of bladder cancer in the United States are early stage and non-muscle invasive disease. Lowgrade Ta lesions and high-grade T1 lesions have similar recurrence rates near 50%; however, high grade T1 lesions have a higher chance of progression than Ta lesions.

While a majority of cases treated with bladder cancer have a favorable prognosis,non-muscle invasive bladder cancer (NMIBC) represents a heterogenous group of diseases to which risk stratification is important to further prognosticate and guide management. Multiple efforts have been madeto risk stratify patients, and NMIBC is generally classified into low, intermediate, and high-risk (T1, high-grade Ta, or carcinoma in situ/Tis) groups (Table 8). Despite continued Bacillus Calmette-Guérin (BCG) therapy, high risk groupshave over a 30% recurrence risk at year one and an over 50% recurrence chance at year five. Moreover, disease progression rates are nearly 20% in high risk patients. Patients who do experience disease progression often must undergo radicalcystectomy, an invasive procedure with high mortality rates.

Atezolizumab and pembrolizumab are both approved first-lineagents in the metastatic setting and avelumab is approved as maintenance after first-line chemotherapy. Pembrolizumab furthermore has an indication in NMIBC refractory to BCG therapy, as previously discussed. Therefore, targeting the PD-L1 pathway is a clinically effective strategy in treating bladder cancer, including in the NMIBC, BCG-unresponsive setting.

We are considering investigating the dual epitope strategy in first-linesetting of previously untreated solid tumors. Muscle invasive bladder cancer may be one of these indications. An ongoing BCG shortage has officially been recognized by expert panels and professional societies as complicating therapeutic access forpatients with NMIBC. This poses a unique opportunity for us and our T-win platform.

Ongoing and planned investigator-initiated trials will provide learnings that we can use in our own development ofIO102-IO103, including in our planned first-line basket trial. See Tables 10 and 11 below for additional details on these trials. Based on the above, IO102-IO103 is planned to be tested in an investigator initiated trial at a U.S. academic sitein combination with anti PD-1 antibody in anti PD-1 naïve, BCG refractory non-muscle invasive bladder cancer.

Future Clinical Development in First-Line Indications

In addition to the ongoing clinical trials discussed above, we plan to conduct a Phase 2 basket trial, IOB-022, which will enable us to investigate multiple solid first-line tumor indications in anti PD-1/PD-L1 treatment naïvepatients with metastatic disease such as NSCLC, UBC, or SCCHN. In the NSCLC portion of the trial we plan to investigate IO102-IO103 in patients expressing PD-L1³50%, a patient population similar to Cohort A in our Phase 1/2 trial of IO102 in combination with pembrolizumab as first line treatment for patients with metastatic NSCLC. We plan to initiatethis trial by the end of 2021 and we are ready to begin enrollment for the NSCLC portion of the basket trial.

Our plannedbasket trial will be a non-comparative, open label, unblinded trial and investigate the safety and efficacy of IO102-IO103 in combination with pembrolizumab in each of the following metastatic first-line indications:

 

  

NSCLC with PD-L1 ³50%

 

  

SCCHN with CPS ³10%

 

  

UBC with CPS ³20%

We plan to first expand the sample size in Phase 2 and then pending the outcome move into a Phase 3 trial in one or more ofthese indications if a sufficiently strong efficacy signal is observed. The primary endpoints of the Phase 2 trial will be dual target of either ORR according RECIST 1.1. or PFS at six months by investigator assessment. Secondary outcome measureswill include PFS, duration of response, CRR, disease control rate, OS, time to response and safety reporting.

Future Clinical Development in Neo-Adjuvant /Adjuvant Setting

In addition to first-line cancer indications, we also plan to investigate the dual epitopeIO102-IO103 used before or after curatively intended surgery as a neo-adjuvant/adjuvant therapy. As with first-line cancer indications, we plan to conduct a Phase 2 basket trial, the IOB-032 trial, which willenable us to investigate multiple first-line solid tumor indications in anti PD-1/PD-L1 naïve settings. We plan to initiate this trial in the first half of 2022 andrecruitment is ongoing.

Our planned basket trial will investigate the safety and efficacy of IO102-IO103 in combinationwith anti-PD 1 in each of the below indications:

 

  

Melanoma

 

  

SCCHN

 

  

Additional indication(s)

Depending on the anti-PD-1 monoclonal antibody therapy we select to combine with IO102-IO103, this trial may include aPhase 1 component which would consist of an integrated concurrent flat dose safety run in. We plan to first expand the sample size in Phase 2 and then move into a Phase 3 trial in one or more of these indications if a sufficiently strongefficacy signal is observed and the tolerability data are generally consistent with previous clinical trials.

Additional Trials in Other First-Line Indications andNeo-Adjuvant and Adjuvant Settings

There are multiple potential indicationexpansion opportunities in various cancer settings with limited anti-PD-1 mAb efficacy or tolerability and toxicity concerns. Both IDO and PD-L1 are highly expressed innumerous other solid tumor indications where anti PD-1-mAb is also approved. Therefore, we believe the potential for the dual epitope IO102-IO103 product candidate in combination with anti PD-1-mAB is significant beyond first-line treatment of advanced melanoma—both as a first-line treatment, but also as a neo-adjuvant (before surgery)/adjuvant (aftersurgery) therapy. A series of investigator initiated trials have been completed and others are ongoing that will inform our own development, including our planned basket trials. Safety data from these trials is included in the tables below.

IO102 (IDO)

IO102 is our fully-owned novel product candidate containing a single IDO-derivedpeptide sequence designed to engage and activate IDO-specific human T cells. This is different from small molecule IDO inhibitors, such as epacadostat, which are designed to block IDO expression on cells.IO102 is the second generation IDO therapy investigated by us. The first IDO therapy we investigated, IO101, is a 9-amino acid peptide investigated in a Phase 1 trial in patients with metastatic NSCLC. TheIO101 peptide is an HLA-A2-restricted, IDO-derived CD8+ T cell epitope. IO102 comprises the original CD8+ T cell epitope encodedby IO101 but also contains additional CD8+ T cell epitopes as well as CD4+ T cell epitopes.

 

136


Table of Contents

IO102 is currently being tested in a randomized Phase 1/2 trial incombination with pembrolizumab standard-of-care in first-line treatment of patients with metastatic NSCLC.

Preclinical Development

IO102 is designed to selectively engage and activate cancer patients’ own T cells to attackIDO-expressing target cells. The activated T cells have demonstrated cytotoxic responses against IDO+ target cells (both tumor cells as well as immune cells) in vitro (Figure 21 below). Further, co-culture of IDO- specific T cells augments expansion of effector T cells against viral and/or tumor antigens such as cytomegalovirus (CMV) (Figure 22 below) and melanomaantigen recognized by T cells (MART-1), illustrating the immunomodulatory function of IDO-specific T cells.

The anti-tumor activity of murine IDO targeting peptide immunotherapy(mIO102) has been demonstrated in many syngeneic tumor models, with data supporting the mechanism of action and validating the treatment approach.

mIO102 treatment has demonstrated synergistic and durable anti-tumor activity in combination with aPD-1 in a preclinical model where IDO expression is confined to the immune cells in the TME (Figures 23 and 24 below).

 

 

LOGO  LOGO

The anti-tumor activity of mIO102 was accompanied by a substantial reduction of IDO1expression in TME (Figure 25 below). In contrast, animals treated with the IDO inhibitor, epacadostat, exhibited little changes in the IDO expression in TME with no durable responses, highlighting the differential MoA between IO102 and IDO smallmolecule inhibitors.

 

 

LOGO

This preclinical data generated for IO102 compared to epacadostat has informed our decisionto pursue our dual mechanism approach rather than an approach focused on small molecule inhibition of IDO.

Table of Contents

Finally, in an anti-PD-1 refractory, ‘cold’ tumor model (B16F10 melanoma), mIO102 treatment demonstrates synergistic anti-tumor activity when combined with tumor associated antigen (TAA) peptide immunotherapy(Figure 26). The anti-tumor activity v mIO102, but not TAA, correlates with the reduction of immunosuppressive, IDO+ myeloid cell types, as well as the reduction of regulatory T cells. Given thatmurine regulatory T cells do not themselves express IDO, the latter observation supports the notion that mIO102 treatment leads to modulation of the TME into a more proinflammatory environment. Finally, a concomitant increase in infiltratingantigen-specific T cells in the TME was observed in the treated animals (Figure 27 below).

Clinical Development of IO102

As described above, our second generation IDO compound, IO102, is currently being tested in an open-labelled, randomized Phase1/2 trial in combination with pembrolizumab with or without chemotherapy as first-line treatment for patients with metastatic NSCLC. Continued development of IO102 will be with IO103 and potentially with IO112 and other antigens as part ofmultiantigen approaches.

IO103 (PD-L1)

IO103 is our fully-owned, novel product candidate containing a single PD-L1-derived peptide designed to engage and activate PD-L1 specific human T cells.

PD-1 and its ligand PD-L1 constitute animportant immune regulatory pathway. The interaction between PD-1 and PD-L1 negatively regulates the proliferation and cytokine production of T cells. Accordingly,cancers upregulate PD-L1 to evade the host immune system and PD-L1 expression is correlated with increased tumor aggressiveness and poor prognosis. PD-L1 expression has been reported for both hematological cancer and solid tumors.

IO103 was tested in a single-arm Phase 2 trial assessing IO103 as a monotherapy inpatients with Basal Cell Carcinoma (BCC) of the skin.

Clinical Development of IO103

IO103 was investigated in a small, mechanism of action focused Phase 2a trial of 10 patients with resectable BCC on astandalone basis. IO103 has previously been investigated in a first in-human study in patients with multiple myeloma and in smoldering myeloma (Tables 9 and 10 above). The primary objective was to investigateobjective and relative (%) reduction of the target lesion as well as the tolerability and immunogenicity after treatment with IO103 in patients with BCC.

Ten patients with resectable BCC were treated with up to nine injections. Adverse events observed during each of the trialswere grade 1–2 and most of these grade 1-2 adverse events were injection site reactions. One patient had a history of decreased vision due to wet age-relatedmacular degeneration prior to inclusion in the trial. This adverse event was not deemed related to treatment with IO103.

All patients exhibited peptide specific immune responses in T cells and inskin-infiltrating lymphocytes. IO103’s continued development will be exclusively as part of the dual epitope candidate IO102-IO103 and potentially other dual epitope candidates combined with our antigens or multi-antigen developments.

IO112 (Arginase 1)

IO112 is our fully-owned, novel product candidate containing a single Arginase1-derived peptide designed to engage and activate Arginase 1-specific human T cells. IO112 is designed to target T cells that recognize epitopes derived from Arginase 1,which is an immunoregulatory enzyme highly expressed in difficult-to-treat tumors associated with high levels of MDSCs including colorectal, breast, prostate andpancreatic and ovarian cancers.

Arginase 1 contributes to immune regulation by catabolizing and limiting the availabilityof arginine, an essential amino acid for immune effector cell survival and growth. Arginase overproduction by immune suppressive cells like myeloid derived suppressor cells and tolerogenic dendritic cells is a well-documented tumor escape mechanism.Increased levels of arginase have been detected on tumor and immune cells in several solid tumor types.

We plan to filean IND/CTA for IO112 in the first half of 2022 and move into a Phase 1/2 trial with IO112 in mid-2022 as part of multi-epitope development with IO102-IO103.

Preclinical Development

IO112 is designed to selectively engage and activate cancer patients’ own T cells to attack Arginase 1-expressing target cells. Upon activation, T cells secrete proinflammatory cytokines such as IFNg and TNFa, therebycontributing to immune modulation of microenvironment.

Immunotherapeutic activity of murine Arginase 1 peptide therapy(mIO112) has been observed in multiple Arginase 1-expressing tumor models. Arginase 1 treatment resulted in a concomitant reduction of Arginase 1+ cells and an increased influx of T cells into the TME. Thetreatment approach enhanced the anti-tumor effect of an anti-PD-1 antibody treatment in a colon adenocarcinoma model, MC38.

Treatment combining Arginase 1 therapy and aPD-1 treatmentresults in synergistic response in a mouse colon cancer model, MC38 (A). In this model, mIO112 treatment (and in combination with aPD-1) results in increased influx of immune cells into TME while promotingenrichment of M1 macrophages (B). In another model (fibrosarcoma, MCA205), increased influx of T cells (CD3 staining) and reduction of Arginase 1-expressing cells in the TME was observed in mice treated withArginase 1 therapy (ovalbumin (OVA) used as irrelevant peptide control) (C).

Clinical Development of IO112

The next indications that we look to explore are difficult to treat cancers, and therefore IO112 is being tested in a singlearm first-in-human Phase 1 trial in patients with arginase-positive solid tumors conducted at Copenhagen University. No data is yet available from this trial. This is anexploratory safety study to determine if this product can be advanced together with IO102-IO103 or as a component of other multiantigen approaches.

We plan to file an IND/CTA for IO112 in the first half of 2022 and move into a Phase 1/2 trial with IO112 in mid-2022 as partof multi-epitope development with IO102-IO103. Longer term, we are considering investigating our product candidates in difficult to treat tumors which often express high levels of arginase, such as colorectal, breast, prostate, pancreatic andovarian cancer. These are all large indications with significant unmet medical need and large commercial potential.

Other Preclinical Compounds

In addition to IO102, IO103 and IO112, we are evaluating additional potential targets that we believe have potential for use insolid tumors. All our compounds in preclinical development target well-documented immunosuppressive molecules that are known to be overexpressed in the TME across a wide range of tumors. These targets are differentially expressed on tumors comparedto normal tissue and cover multiple cancer indications. For example, we are evaluating the potential anti-tumor effect of a novel immune-modulatory cancer therapy using TGF-ß-derived peptides (IO170) in murine tumor models. Transforming growthfactor-ß (TGF-ß) is one of the key molecules that contribute to immunosuppression and it is produced in large amounts in the TME by not only cancer cells but also by suppressive and regulatory cells.

Collaborations

Agreements with Herlev Hospital

Option Agreements with Herlev

We have entered into a number of agreements with Herlev and Gentofte Hospital (Herlev) in Denmark granting us options toacquire certain intellectual property rights related to our programs. The primary agreement governing these rights is Framework Assignment Agreement (the Framework Assignment Agreement) that we entered into with Herlev in May 2016. Under theFramework Assignment Agreement, Herlev grants us options to acquire licenses to data and assignments of patent rights in and to certain inventions related to activating or boosting T cells that react towards regulatory immune cells for the treatmentand prevention of cancer (the Field) developed by Drs. Mads Hald and Inge Marie Svane. We have a period of three months after disclosure by Herlev of any applicable invention to exercise our option with respect to such invention in the Field. Uponexercise of any option, we will negotiate in good faith with Herlev regarding the terms of an assignment agreement for such invention in the Field. If we are unable to agree to terms of such assignment within six months of exercise of the option,Herlev will have no further obligation to continue negotiations with respect to such invention.

The Framework AssignmentAgreement will continue until termination by either party. Under the Framework Assignment Agreement, either party may terminate the agreement (1) for convenience, upon six months’ prior written notice or (2) for the other party’suncured material breach. Termination of the Framework Assignment Agreement for any reason will not affect any assignment agreement entered into prior to such termination.

We have exercised our options granted under the Framework Assignment Agreement, and other option agreements with Herlev, andobtained assignments and licenses related to certain inventions, including inventions related to our lead product candidates, IO102, IO103 and IO112.

Assignment Agreements with Herlev

In January 2015, January 2017 and December 2018, respectively, we exercised options granted by Herlev, and acquiredHerlev’s rights and title in and to the patent applications related to Indoleamine 2, 3-dioxygenase based immunotherapies, PD-L1-based immunotherapies and PD-LI peptides for use in cancer vaccines, such as our T-win product candidates, and Arginase specific T cells. In connection with such acquisitions, Herlev has also granted usnon-exclusive licenses under any clinical data related to such patent rights arising at Herlev for the purpose of developing and commercializing the inventions and patent rights. The agreements pursuant towhich we have obtained these rights and licenses (the Assignment Agreements) are non-terminable.

Pursuant to the Assignment Agreements and other similar agreements with Herlev, we have to date paid Herlev an aggregate ofDKK 2.6 million and are obligated to pay future contingent payments and royalties, including upon achieving potential regulatory milestones and low single digit royalties on net sales from sales of products incorporating the acquired patent rightsand other revenues arising from the acquired patent rights. Upon the occurrence of a change of control, stock or asset sale or IPO, all outstanding milestone payments under

such agreements will become due immediately in the aggregate of approximately DKK 10.2 million (which is approximately $1.7 million based on the exchange rate of DKK 6.08 to one U.S. dollar onDecember 31, 2020). We have the right to buy-out all remaining payment obligations under the each Assignment Agreement at any time by paying DKK 20 million (for each of thePD-L1 technology and IDO technology) or DKK 10 million (for the Arginase technology) to Herlev.

Under the Assignment Agreements, we control all rights to the covered patents and, with respect to the PD-L1 and Arginase technology, are required to use our best reasonable efforts to manage, prosecute, maintain and enforce, and we are not permitted to abandon, the acquired patent rights certain markets, includingDenmark and certain other EU countries, the UK, the US, Canada, Japan and China.

Research Agreements with Herlev

In connection with the Framework Assignment Agreement, we entered into a Framework Cooperation Agreement (the FrameworkCooperation Agreement) with Herlev, in which we agreed to cooperate with Herlev, either through co-financed research or sponsored research, for certain agreed-upon research programs to develop therapies aimedat activating or boosting T cells that react towards regulatory immune cells for the treatment and prevention of cancer (the Field). Pursuant to the Framework Cooperation Agreement, we will have the option to acquire all intellectual property rightsin inventions developed in the course of any research program, under the terms of the Framework Assignment Agreement. The Framework Cooperation Agreement does not have a set expiration date, but may be terminated by either party (1) forconvenience, upon six months’ prior written notice, or (2) for the other party’s uncured material breach.

Each research program under the Framework Cooperation Agreement will be conducted under a separate cooperation agreement(each, a Cooperation Agreement). We are currently engaged in six co-financed or sponsored research programs in the Field, each under a separate Cooperation Agreement. Each Cooperation Agreement will continueuntil the completion of the applicable research program, and either party may terminate such Cooperation Agreement, (1) for convenience, upon three months’ prior written notice, or (2) for the other party’s uncured materialbreach.

Additionally, we have entered into a separate agreement with Herlev pursuant to which we will be obligated to paya cash fee in the amount of DKK 5.0 million (which is approximately $0.8 million based on the exchange rate of DKK 6.08 to one U.S. dollar on December 31, 2020) upon the occurrence of a change of control, stock or asset sale or IPO.

Clinical Trial Research Agreement with Cliniques Universitaires Saint-Luc

In November 2019, we entered into a Clinical Trial Research Agreement (the Clinical Trial Agreement) withCliniques universitaires Saint-Luc (Saint-Luc) in Belgium in order to conduct an investigator-initiated study regarding the activity and safety of peptide-basedimmunotherapy in the pre-operative setting for patients with squamous-cell carcinoma of the head and neck (the Saint-Luc Study). TheSaint-Luc Study is designed as an umbrella trial enabling the testing of multiple of our compounds, including IO102, IO103 and IO112, after initial testing of IO102 in a monotherapy setting. We are responsiblefor payment of costs associated with the Saint-Luc Study in accordance with an agreed-upon budget.

Saint-Luc is the sponsor of the Saint-LucStudy and owns all inventions arising from, and data and results generated in, the Saint-Luc Study, and has agreed to grant us an exclusive license to all data and results generated during the Saint-Luc Study. In addition, we have the exclusive right to evaluate, prepare, file, prosecute and maintain patent rights related to any inventions, and we will own all such patented inventions. Saint-Luc is required to take all actions necessary to assign rights in any such patents to us.

The Clinical Trial Agreement will continue for the term of the Saint-Luc Study, unlessterminated earlier by either party for convenience or the other party’s material breach, subject to applicable notice and cure periods. In addition, we have the right to terminate the Clinical Trial Agreement for various reasons related to theconduct of the Saint-Luc Study.

Competition

Our industry is intensely competitive and subject to rapid and significant technological change. While we believe that ourknowledge, experience and scientific resources provide us with competitive advantages, we face substantial competition from major pharmaceutical companies and biotechnology companies, academic institutions, government agencies and other public andprivate research organizations that conduct research, seek patent protection and established collaborative arrangements for the research, development, manufacturing and commercialization of cancer immunotherapies. Many of our competitors havesignificantly greater financial, technical and human resources. Smaller and early-stage companies may also prove to be significant competitors, particularly through collaborative arrangements with large and established companies. As a result, ourcompetitors may discover, develop, license or commercialize products before or more successfully than we do.

We facecompetition with respect to our current product candidates, and will face competition with respect to future product candidates, from segments of the pharmaceutical, biotechnology and other related markets that pursue immune-oncology treatments.

Specifically, there are many companies that commercialize or are developing immuno-oncology treatments for cancerincluding large pharmaceutical and biotechnology companies such as Amgen, AstraZeneca, BMS, Merck, Novartis, Pfizer and Roche, and its subsidiary Genentech.

Table of Contents

In melanoma specifically, the dominant market players are nivolumab,marketed by BMS and Ono, nivolumab & ipilimumab, marketed by BMS and Ono, and pembrolizumab, marketed by Merck. We are also aware of several companies testing their compounds in combination with nivolumab or pembrolizumab. Among those inlate stage development are Nektar Therapeutics (bempegaldesleukin) and BMS (relatlimab). In earlier stage development there are also BioNTech with NEO-PV-01 andKaryopharm with selinexor.

We are not aware of any human peptides targeting the TME that are currently in late stagedevelopment for melanoma, NSCLC, bladder cancer or other solid tumors.

Our competitors may obtain regulatory approval oftheir products more rapidly than we may or may obtain patent protection or other intellectual property rights that limit our ability to develop or commercialize our product candidates. Our competitors may also develop drugs that are more effective,more convenient, more widely used and less costly or have a better safety profile than our products and these competitors may also be more successful than us in manufacturing and marketing their products. Our competitors will also compete with us inrecruiting and retaining qualified scientific, management and commercial personnel, establishing clinical trial sites and patient registration for clinical trials, as well as in acquiring technologies complementary to, or necessary for, ourprograms.

Furthermore, we also face competition more broadly across the market for cost-effective and reimbursable cancertreatments. The most common methods of treating patients with cancer are surgery, radiation and drug therapy, including chemotherapy, hormone therapy and targeted drug therapy, or a combination of such methods. There are a variety of available drugtherapies marketed for cancer. In many cases, these drugs are administered in combination to enhance efficacy. While our product candidates, if any are approved, may compete with these existing drug and other therapies, to the extent they areultimately used in combination with or as an adjunct to these therapies, our product candidates may not be competitive with them.

Some of these drugs are branded and subject to patent protection, and others are available on a generic basis. Insurers andother third-party payors may also encourage the use of generic products or specific branded products. We expect that if our product candidates are approved, they will be priced at a significant premium over competitive generic, including brandedgeneric, products. As a result, obtaining market acceptance of, and a gaining significant share of the market for, any of our product candidates that we successfully introduce to the market will pose challenges. In addition, many companies aredeveloping new therapeutics, and we cannot predict what the standard of care will be as our product candidates progress through clinical development.

The acquisition or licensing of pharmaceutical products is also very competitive. If we seek to acquire or license products,we will face substantial competition from a number of more established companies, some of which have acknowledged strategies to license or acquire products and many of which are bigger than us and have more institutional experience and greater cashflows than we have. These more established companies may have competitive advantages over us, as may other emerging companies taking similar or different approaches to product licenses and/or acquisitions. In addition, a number of establishedresearch-based pharmaceutical and biotechnology companies may acquire products in late stages of development to augment their internal product lines, which may provide those companies with an even greater competitive advantage.

Manufacturing and Supply

Our compounds are linear peptides formulated as lyophilized powders to ensure long-term shelf-life and reconstituted with waterfor injection and emulsified with adjuvant prior to subcutaneously administration. The manufacturing process of our compounds has multiple advantages over other immuno-oncology compounds. The manufacturing process is based on well-understood processsolid state peptide synthesis and data has proven our compounds to be stable for long period at easy-to-administer temperatures. The cost of goods sold for both trialsand commercial use is expected to be relatively low.

Table of Contents

We currently do not own or operate any manufacturing facilities nor have anyplans do so in the foreseeable future. We rely on, and expect to continue to rely on, third-party contract development and manufacturing organizations (CDMOs) to continue the development and the optimization of our product candidates and to ensurethat suitable manufacturing processes are in place for both present scales and future commercial scales of production of our product candidates. This ensures that all products manufactured under our responsibility are done so in accordance withrelevant regulatory requirements and approval and includes those product materials intended for use in our preclinical and clinical testing, as well as commercial manufacture.

We believe that our strategy and workforce allow us to maintain an efficient infrastructure and ensure we do not need toinvest in expensive manufacturing facilities and equipment. The personnel within the organization enable us to focus our expertise and resources on the development of our product candidates and the management of third parties.

To date, we have obtained active pharmaceutical ingredients from qualified facilities with the relevant expertise tomanufacture our drug substances. Likewise, suitably qualified facilities with relevant experience have been used to manufacture our drug products. All third parties are assessed under our quality system and appropriate quality agreements to ensurecompliance are in place. We maintain agreements with our manufacturers and ensure that confidentiality and intellectual property provisions to protect our proprietary rights related to our product candidates are in place.

We are in the process of further optimizing and developing our supply chain for each of our product candidates to ensurecontinuity of supply and capacity for intended commercial scales.

Commercialization

We hold worldwide development and commercial rights to our pipeline of immuno-oncology programs, and we intend to commercializeour product candidates, if approved, in key geographies. We do not currently have our own marketing, sales, or distribution capabilities. To commercialize IO102-IO103, if approved for commercial sale, we would have to develop a sales and marketinginfrastructure.

Subject to receiving marketing approvals, we expect to commence commercialization activities by buildinga focused sales and marketing organization to sell our products. We believe that such an organization will be able to address the community of oncologists who are the key specialists in treating the patient populations for which our productcandidates are being developed. We may selectively enter into distribution and other marketing arrangements with third parties for any of our product candidates that obtain marketing approval if we believe these collaborations could maximize thevalue of our product candidates.

We also plan to build a marketing and sales management organization to create andimplement marketing strategies for any products that we market through our own sales organization and to oversee and support our sales force. The responsibilities of the marketing organization would include developing educational initiatives withrespect to approved products and establishing relationships with researchers and practitioners in relevant fields of medicine.

Intellectual Property

We strive to protect and enhance the proprietary technology, inventions, and improvements that are commerciallyimportant to our business, including seeking, maintaining, and defending patent rights, whether developed internally or assigned from third parties. We own the issued patents and patent applications relating to all compounds in our portfolio. Ourpolicy includes seeking to protect our proprietary position by, among other methods, filing patent applications, in the United States and in jurisdictions outside of the United States, directed to our proprietary technology, inventions,improvements, and product candidates that are important to the development and implementation of our business. We also rely on trade secrets and know-how relating to our

proprietary technology and product candidates, continued innovation, and in-licensing opportunities to develop, strengthen and maintain ourproprietary position in the field of immunotherapy. We also plan to rely on data exclusivity, market exclusivity, and supplementary protection certificates / patent term extensions (SPC/PTE) when available. Our commercial success will depend in parton our ability to obtain and maintain patent and other proprietary protection for our technology, inventions, and improvements; to preserve the confidentiality of our trade secrets and know-how; toobtain and maintain licenses to use intellectual property owned by third parties; to defend and enforce our proprietary rights, including any patents that we may own in the future; and to operate without infringing, misappropriating or otherwiseviolating the valid and enforceable patents and other proprietary rights of third parties. For more information, please see “Risk Factors—Risks Related to Intellectual Property.”

Government Regulation

The FDA and other regulatory authorities at federal, state and local levels, as well as in foreign countries, extensivelyregulate, among other things, the research, development, testing, manufacture, quality control, import, export, safety, effectiveness, labeling, packaging, storage, distribution, tracking, record keeping, approval, advertising, promotion, marketing,post-approval monitoring and post-approval reporting of biological products such as those we are developing. We, along with our vendors, collaboration partners, CROs and CMOs, will be required to navigate the various preclinical, clinical,manufacturing and commercial approval requirements of the governing regulatory agencies of the countries in which we wish to conduct studies or seek approval of our product candidates. The process of obtaining regulatory approvals of biologicalproducts and ensuring subsequent compliance with appropriate federal, state, local, and foreign statutes and regulations requires the expenditure of substantial time and financial resources.

In the United States, where we are initially focusing our product development, the FDA regulates biologics under the FDCA andthe Public Health Service Act (PHSA) and their implementing regulations. Biologics are also subject to other federal, state and local statutes and regulations. Our product candidates are early-stage and have not been approved by the FDA formarketing in the United States.

Our product candidates must be approved for therapeutic indications by the FDA through aBLA (Biologics License Application) before they may be marketed in the United States. The process generally involves the following:

 

  

completion of extensive preclinical studies in accordance with applicable regulations, including studiesconducted in accordance with GLP requirements;

 

  

submission to the FDA of an IND, which must become effective before clinical trials to be conducted in theU.S. may begin and must be updated annually or when significant changes are made;

 

  

approval by an IRB or independent ethics committee at each clinical trial site before each trial may beinitiated;

 

  

performance of adequate and well-controlled clinical trials in accordance with GCP requirements and otherclinical trial-related regulations to establish the safety and efficacy of the investigational biologic for each proposed indication;

 

  

preparation and submission to the FDA of a BLA, after completion of all pivotal trials;

 

  

payment of user fees for FDA review of the BLA;

 

  

potential review of the product application by an FDA advisory committee, where appropriate and if applicable;

 

  

a determination by the FDA within 60 days of its receipt of a BLA to file the application for review;

 

  

satisfactory completion of an FDA advisory committee review, if applicable;

 

152

satisfactory completion of one or more FDA pre-approval inspections ofthe manufacturing facility or facilities where the biologic will be produced to assess compliance with cGMP to assure that the facilities, methods, and controls are adequate to preserve the product’s identity and continued safety, purity, andpotency;

 

  

potential FDA audit of the preclinical and clinical trial sites that generated the data in support of the BLA;

 

  

FDA review and approval of the BLA, including consideration of the views of any FDA advisory committee, priorto any commercial marketing or sale of the product in the United States; and

 

  

compliance with any post-approval requirements, including the potential requirement to implement a RiskEvaluation and Mitigation Strategy (REMS) or to conduct a post-approval study.

Nonclinical andClinical Trials

Nonclinical Trials

Before testing any biologic product in humans, the product candidate must undergo rigorous nonclinical testing in vitro andin vivo. Such nonclinical in vitro and in vivo animal studies assess safety and in some cases to establish the rationale for therapeutic use. The conduct of nonclinical studies is subject to federal and state regulations and requirements,including GLP requirements for safety and toxicology studies. The results of the nonclinical studies, together with manufacturing information, a proposed clinical trial protocol, and analytical data must be submitted to the FDA as part of an INDprior to the start of clinical studies in humans. However, some long-term nonclinical testing may continue after the IND is submitted.

Clinical Trials

Clinical trials to evaluate therapeutic indications to support BLAs for marketing approval are typically conducted in threesequential phases, which may overlap.

 

  

Phase 1—Phase 1 clinical trials involve initial introduction of the investigational product into healthyhuman volunteers or patients with the target disease or condition. These studies are typically designed to test the safety, dosage tolerance, absorption, metabolism, distribution, and excretion of the investigational product in humans, evaluate theside effects associated with increasing doses, and, if possible, to gain early evidence of effectiveness;

 

  

Phase 2—Phase 2 clinical trials typically involve administration of the investigational product to alimited patient population with a specified disease or condition to evaluate the preliminary efficacy, optimal dosages and dosing schedule and to identify possible adverse side effects and safety risks. Phase 1 trials are sometimes combinedwith Phase 2 trials. These trials are known as Phase 1/2 trials. Generally, a Phase 1/2 trial is conducted as a single trial that has the characteristics of both a Phase 1 trial (as described above) and a Phase 2 trial. Multiple Phase 2 clinicaltrials may be conducted to obtain information prior to beginning larger and more expensive Phase 3 clinical trials. Phase 2 trials may be conducted as basket trials where a single investigational drug or drug combination is studied across multiplecancer populations defined by disease stage, histology, number of prior therapies, genetic or other biomarkers, or demographic characteristics.; and

 

  

Phase 3—Phase 3 clinical trials typically involve administration of the investigational product to anexpanded patient population to further evaluate dosage, to provide statistically significant evidence of clinical efficacy and to further test for safety, generally at multiple geographically dispersed clinical trial sites. These clinical trials areintended to establish the overall risk/benefit ratio of the investigational product and to provide an adequate basis for approval. Accordingly, these are generally known as registrational trials. Generally, two adequate and well-controlled Phase 3clinical trials are required by the FDA for approval of a BLA.

 

153


Table of Contents

Post-approval trials, sometimes referred to as Phase 4 clinical trials,may be conducted after initial marketing approval. These trials are used to gain additional experience from the treatment of patients in the intended therapeutic indication and are commonly intended to generate additional information regardingrisks, benefits, and optimal use of the product in a clinical setting. In certain instances, the FDA may mandate the performance of Phase 4 clinical trials as a condition of approval of a BLA.

Investigational New Drug — Authorization to Conduct Clinical Trials in US

An IND is a request for authorization from the FDA to administer an investigational biologic product to humans and to ship suchproducts in interstate commerce for use in investigational clinical trials. INDs must become effective before clinical trials in the U.S. may begin. The central focus of an IND submission is on the general investigational plan and the protocol(s)for clinical studies. The IND also includes results of animal and in vitro studies assessing the toxicology, carnicogenicity, formulation, pharmacokinetics, pharmacology, and pharmacodynamic characteristics of the product; chemistry, manufacturing,and controls information; any available human data or literature to support the use of the investigational product; and a proposed clinical trial protocol.

The IND automatically becomes effective 30 days after receipt of the submission by the FDA, unless the FDA, within the 30-day time period, raises concerns or questions about the conduct of the clinical trial, including concerns that human research subjects will be exposed to unreasonable health risks, and imposes a clinical hold. Insuch a case, the IND sponsor must resolve any outstanding concerns before the clinical trial can begin. Accordingly, submission of an IND may or may not result in FDA authorization to begin a trial. A separate submission to an existing IND must alsobe made for each successive clinical trial conducted during product development of a product candidate, and the FDA must grant permission, either explicitly or implicitly by not objecting, before each clinical trial can begin.

Clinical trials involve the administration of the product candidate to healthy volunteers or patients under the supervision ofqualified investigators, generally physicians not employed by or under the trial sponsor’s control in accordance with GCP requirements, which include the requirements that all research subjects provide their informed consent for theirparticipation in any clinical trial. Clinical trials are conducted under protocols detailing, among other things, the objectives of the clinical trial, dosing procedures, subject selection, and exclusion criteria, and the parameters and criteria tobe used in monitoring safety and evaluating effectiveness. Each protocol, and any subsequent amendments to the protocol, must be submitted to the FDA as part of the IND. Furthermore, each clinical trial must be reviewed and approved by an IRB foreach institution at which the clinical trial will be conducted to ensure that the risks to individuals participating in the clinical trials are minimized and are reasonably related to the anticipated benefits. The IRB also approves the informedconsent form that must be provided to each clinical trial subject or his or her legal representative, and must monitor the clinical trial until completed.

The FDA, the IRB, or the sponsor may suspend or discontinue a clinical trial at any time on various grounds, including afinding that the subjects are being exposed to an unacceptable health risk.

Some studies also include oversight by anindependent group of qualified experts organized by the clinical study sponsor, known as a data safety monitoring board, which provides authorization for whether or not a study may move forward at designated check points based on access to certaindata from the study and may halt the clinical trial if it determines that there is an unacceptable safety risk for subjects or other grounds, such as no demonstration of efficacy.

There also are requirements governing the reporting of ongoing clinical trials and completed clinical trials to publicregistries. Information about applicable clinical trials, including clinical trials results, must be submitted within specific timeframes to the National Institutes of Health (NIH) for publication on the www.clinicaltrials.gov website.

Progress reports detailing the results of the clinical trials, among other information, must be submitted at least annually tothe FDA and IND safety reports must be submitted to the FDA and the investigators within

fifteen days after the trial sponsor determines the information qualifies for reporting for serious and unexpected suspected adverse reactions, findings from other studies or animal or invitro testing that suggest a significant risk for human participants exposed to the drug or biological product, and any clinically important increase in the rate of a serious suspected adverse reaction over that listed in the protocol orinvestigator brochure. The sponsor must also notify the FDA of any unexpected fatal or life-threatening suspected adverse reaction as soon as possible, but in no case later than seven calendar days after the sponsor’s initial receipt of theinformation.

A sponsor who wishes to conduct a clinical trial outside of the United States may, but need not, obtain FDAauthorization to conduct the clinical trial under an IND. The FDA will accept a well-designed and well-conducted foreign clinical study not conducted under an IND if, among other things, the study was conducted in accordance with GCP, and the FDA isable to validate the data through an onsite inspection if deemed necessary.

FDA Review Process

Assuming successful completion of the required clinical testing, a BLA requesting approval to market the product for one ormore indications must be submitted to FDA. A BLA is a request for approval to market a new biological product for one or more specified indications. The BLA must include all relevant data available from pertinent nonclinical and clinical studies,including negative or ambiguous results as well as positive findings, together with detailed information relating to the product’s chemistry, manufacturing, controls, and proposed labeling, among other things. Data may come fromcompany-sponsored clinical trials intended to test the safety and efficacy of a product’s use or from a number of alternative sources, including studies initiated by investigators not from the company. To support marketing approval, the datasubmitted must be sufficient in quality and quantity to establish the safety, purity, and potency of the investigational biological product, to the satisfaction of the FDA. FDA approval of a BLA must be obtained before a product may be marketed inthe United States.

In addition, under the Pediatric Research Equity Act (PREA) certain BLAs and certain supplements to aBLA must contain data to assess the safety and effectiveness of the product candidate for the claimed indications in all relevant pediatric subpopulations and to support dosing and administration for each pediatric subpopulation for which theproduct is safe and effective, unless the sponsor has received a deferral or waiver. A sponsor who is planning to submit a marketing application for a product that includes a new active ingredient, new indication, new dosage form, new dosing regimenor new route of administration must submit an initial Pediatric Study Plan within 60 days after an end-of-Phase 2 meeting or as may be agreed between the sponsor andFDA. Unless otherwise required by regulation, PREA does not apply to a product for an indication for which orphan designation has been granted.

The FDA reviews all submitted BLAs before it accepts them for filing, and may request additional information rather thanaccepting the BLA for filing. The FDA must make a decision on accepting a BLA for filing within 60 days of receipt, and such decision could include a refusal to file by the FDA. Once the submission is accepted for filing, the FDA begins an in-depth substantive review of the application. The FDA reviews a BLA to determine, among other things, whether the product is safe and effective and whether the facility in which it is manufactured, processed,packaged or held meets standards designed to assure continued safety, quality and purity. Under the goals and polices agreed to by the FDA under the Prescription Drug User Fee Act (PDUFA) the FDA targets ten months, from the filing date, in which tocomplete its initial review of an original BLA and respond to the applicant, and six months from the filing date of an original BLA filed for priority review. The FDA does not always meet its PDUFA goal dates for standard or priority BLAs, and thereview process may be extended by FDA requests for additional information or clarification.

Further, under PDUFA, asamended, each BLA must be accompanied by a user fee and the sponsor of an approved BLA is also subject to an annual program fee. FDA adjusts the PDUFA user fees on an annual basis. Fee waivers or reductions may be available in certain circumstances,including a waiver of the application fee for the first BLA filed by a small business. Additionally, no user fees are assessed on BLAs for products designated as orphan drugs, unless the product applicant also seeks approval for a non-orphan indication.

The FDA may refer an application for a biologic product to anadvisory committee. An advisory committee is a panel of independent experts, including clinicians and other scientific experts, which reviews, evaluates and

 

155


Table of Contents

provides a recommendation as to whether the application should be approved and under what conditions. The FDA is not bound by the recommendations of an advisory committee, but it considers suchrecommendations carefully when making decisions.

Before approving a BLA, the FDA typically will inspect the facility orfacilities where the product is manufactured. The FDA will not approve an application unless it determines that the manufacturing processes and facilities are in compliance with cGMP requirements and adequate to assure consistent production withinrequired specifications. Additionally, before approving a BLA, the FDA may inspect one or more clinical trial sites to assure compliance with GCP, and other requirements, and the integrity of the clinical data submitted to the FDA.

The FDA also may require submission of a REMS (Risk Evaluation and Mitigation Strategy) as a condition for approving the BLAto ensure that the benefits of the product outweigh its risks. The REMS could include medication guides, physician communication plans, assessment plans, and/or elements to assure safe use, such as restricted distribution methods, patientregistries, or other risk-minimization tools.

After evaluating the application and all related information, including theadvisory committee recommendation, if any, and inspection reports regarding the manufacturing facilities and clinical trial sites, the FDA may issue an approval letter, or, in some cases, a Complete Response Letter. A Complete Response Letterindicates that the review cycle of the application is complete and the application is not ready for approval. A Complete Response Letter will usually describe all of the deficiencies that the FDA has identified in the BLA, except where the FDAdetermines that the data supporting the application are inadequate to support approval, and the FDA may issue the Complete Response Letter without first conducting required inspections, testing submitted production lots, and/or reviewing proposedlabeling. In issuing the Complete Response Letter, the FDA may recommend actions that the applicant might take to place the BLA in condition for approval, including requests for additional information or clarification. Even with submission of thisadditional information, the FDA ultimately may decide that the application does not satisfy the regulatory criteria for approval. If and when those conditions have been met to the FDA’s satisfaction, the FDA will typically issue an approvalletter. An approval letter authorizes commercial marketing of the product with specific prescribing information for specific indications.

Even if the FDA approves a biologic product, depending on the specific risk(s) to be addressed, the FDA may limit the approvedindications for use, require that contraindications, warnings or precautions be included in the approved labeling, require that post-approval studies, including Phase 4 clinical trials, be conducted to further assess a product’s safetyafter approval, require testing and surveillance programs to monitor the product after commercialization, or impose other conditions, including distribution and use restrictions or other risk management mechanisms under a REMS, which can materiallyaffect the potential market and profitability of the product. The FDA may prevent or limit further marketing of a product based on the results of post-marketing studies or surveillance programs. After approval, some types of changes to the approvedproduct, such as adding new indications, manufacturing changes, and additional labeling claims, are subject to further testing requirements and FDA review and approval.

Orphan Designation and Exclusivity

Under the Orphan Drug Act, the FDA may grant orphan drug designation (ODD) to a biologic product intended to treat a raredisease or condition, defined as a disease or condition with either a patient population of fewer than 200,000 individuals in the United States, or a patient population greater than 200,000 individuals in the United States when there is noreasonable expectation that the cost of developing and making available the drug or biological product in the United States will be recovered from sales in the United States of that drug or biological product. ODD must be requested before submittinga BLA. After the FDA grants ODD, the identity of the therapeutic agent and its orphan designation are disclosed publicly by the FDA.

A product that has received ODD and subsequently is the first FDA approved biologic product for the disease for which it hassuch designation, is entitled to orphan product exclusivity for the approved indication. The designation

 

156


Table of Contents

does not convey any advantage in, or shorten the duration of, the regulatory review or approval process. Orphan exclusivity means that the FDA may not approve any other applications, including afull BLA, to market the same drug or biological product for the same indication for seven years from the date of approval of the BLA, except in limited circumstances, such as a showing of clinical superiority to the product with orphan exclusivityor if the FDA finds that the holder of the orphan exclusivity has not shown that it can assure the availability of sufficient quantities of the orphan product to meet the needs of patients with the disease or condition for which the product wasapproved. Orphan exclusivity does not prevent the FDA from approving a different drug or biological product for the same disease or condition, or the same product for a different disease or condition. Among the other benefits of ODD are tax creditsfor certain research and a waiver of the BLA application user fee.

A product that has received ODD may not receive orphanexclusivity if it is approved for a use that is broader than the indication for which it received ODD. In addition, exclusive marketing rights in the United States may be lost if the FDA later determines that the request for designation wasmaterially defective or if the manufacturer is unable to assure sufficient quantities of the product to meet the needs of the patients with the rare disease or condition.

Expedited Development and Review Programs

The FDA maintains several programs intended to facilitate and expedite development and review of new biologic products toaddress unmet medical needs in the treatment of serious or life-threatening diseases or conditions. These programs include Fast Track designation, Breakthrough Therapy designation, priority review and Accelerated Approval.

A new biologic product is eligible for Fast Track designation if it is intended to treat a serious or life-threatening diseaseor condition and demonstrates the potential to address unmet medical needs for such disease or condition. Fast track designation applies to the biologic product, or combination of drugs and biologic products, and the specific indication for which itis being studied. Fast Track designation may provide increased opportunities for sponsor interactions with the FDA during preclinical and clinical development, in addition to the potential for rolling review once a marketing application is filed,meaning that the FDA may consider for review sections of the BLA on a rolling basis before the complete application is submitted, if the sponsor provides a schedule for the submission of the sections of the BLA, the FDA agrees to accept sections ofthe BLA and determines that the schedule is acceptable, and the sponsor pays any required user fees upon submission of the first section of the application. FDA may revoke the Fast Track designation if it believes that the designation is no longersupported by data emerging in the clinical trial process.

In addition, a new biologic product may be eligible forBreakthrough Therapy designation if it is intended to treat a serious or life-threatening disease or condition and preliminary clinical evidence indicates that the drug or biological product, alone or in combination with or more other biologicproducts, may demonstrate substantial improvement over existing therapies on one or more clinically significant endpoints, such as substantial treatment effects observed early in clinical development. Breakthrough Therapy designation provides allthe features of Fast Track designation in addition to intensive guidance on an efficient development program beginning as early as Phase 1, and FDA organizational commitment to expedited development, including involvement of senior managers andexperienced review and regulatory staff in a proactive, collaborative, cross-disciplinary review, where appropriate.

Anybiologic product submitted to the FDA for approval, including a product with Fast Track, or BTD designation, may also be eligible for priority review. A product is eligible for priority review if it is intended to treat a serious condition, and ifapproved, would provide a significant improvement in safety or effectiveness. For original BLAs, priority review designation means the FDA’s goal is to take action on the marketing application within six months of the 60-day filing date (compared with ten months under standard review).

In addition,biologic products studied for their safety and effectiveness in treating serious or life-threatening illnesses and that provide meaningful therapeutic benefit over existing treatments may be eligible for accelerated

approval and may be approved on the basis of adequate and well-controlled clinical trials establishing an effect on a surrogate endpoint that is reasonably likely to predict clinical benefit, oron a clinical endpoint that can be measured earlier than irreversible morbidity or mortality, that is reasonably likely to predict an effect on irreversible morbidity or mortality or other clinical benefit, taking into account the severity, rarity,or prevalence of the condition and the availability or lack of alternative treatments. As a condition of approval, the FDA may require a sponsor of such product receiving accelerated approval to perform post-marketing studies to verify and describethe predicted effect on irreversible morbidity or mortality or other clinical endpoint, and the product may be subject to accelerated withdrawal procedures. Products granted accelerated approval must meet the same statutory standards for safety andeffectiveness as those granted traditional approval. In addition, the FDA currently requires as a condition for accelerated approval pre-approval of promotional materials, which could adversely impact the timing of the commercial launch of theproduct.

Even if a product qualifies for one or more of these programs, the FDA may later decide that the product nolonger meets the conditions for qualification or decide that the time period for FDA review or approval will not be shortened. Fast Track designation, Breakthrough Therapy designation, priority review, and accelerated approval do not change thescientific or medical standards for approval or the quality of evidence necessary to support approval but may expedite the development or review process.

After a device is placed on the market, it remains subject to significant regulatory requirements. Medical devices may bemarketed only for the uses and indications for which they are cleared or approved. Device manufacturers must also establish registration and device listings with the FDA. Further, a medical device manufacturer’s manufacturing processes andthose of its suppliers are required to comply with the applicable portions of the quality system regulation (QSR), which cover the methods and documentation of the design, testing, production, processes, controls, quality assurance, labeling,packaging and shipping of medical devices. Domestic facility records and manufacturing processes are subject to periodic unscheduled inspections by the FDA. The FDA also may inspect foreign facilities that export products to the U.S.

Device manufacturers are also subject to FDA’s medical device reporting regulations, which require that a manufacturerreport to the FDA if a device it markets may have caused or contributed to a death or serious injury, or has malfunctioned and the device or a similar device that it markets would be likely to cause or contribute to a death or serious injury, if themalfunction were to recur, and FDA’s correction and removal reporting regulations, which require that manufacturers report to the FDA corrections or removals if undertaken to reduce a risk to health posed by the device or to remedy a violationof the FDCA that may present a risk to health. A medical device manufacturer’s manufacturing processes and those of its suppliers are required to comply with the applicable portions of the Quality System Regulation, which covers the methods anddocumentation of the design, testing, production, processes, controls, quality assurance, labeling, packaging and shipping of medical devices. Domestic facility records and manufacturing processes are subject to periodic unscheduled inspections bythe FDA. The FDA also may inspect foreign facilities that export products to the United States.

U.S. Post-approval Requirements

Biological products manufactured or distributed pursuant to FDA approvals are subject to pervasive and continuingregulation by the FDA, including, among other things, requirements relating to recordkeeping, periodic reporting, product sampling and distribution, reporting of adverse experiences with the product, complying with promotion and advertisingrequirements, which include restrictions on promoting products for unapproved uses or patient populations (known as “off-label use”) and limitations on industry-sponsored scientific and educationalactivities.

The FDA may impose a number of post-approval requirements as a condition of approval of a BLA. For example,the FDA may require post-market testing, including Phase 4 clinical trials, and surveillance to further assess and monitor the product’s safety and effectiveness after commercialization.

 

158


Table of Contents

In addition, product manufacturers and their subcontractors involved in themanufacture and distribution of approved products are required to register their establishments with the FDA and certain state agencies and are subject to periodic unannounced inspections by the FDA and certain state agencies for compliance withongoing regulatory requirements, including cGMP, which imposes certain procedural and documentation requirements upon us and our CMOs. Changes to the manufacturing process are strictly regulated, and often require prior FDA approval before beingimplemented. FDA regulations also require investigation and correction of any deviations from cGMP and impose reporting requirements upon the sponsor and any third-party manufacturers that we may decide to use. Accordingly, manufacturers mustcontinue to expend time, money and effort in the area of production and quality control to maintain compliance with cGMP and other aspects of regulatory compliance. Failure to comply with statutory and regulatory requirements can subject amanufacturer to possible legal or regulatory action, such as warning letters, suspension of manufacturing, product seizures, injunctions, and civil or criminal penalties. There is also a continuing, annual program fee for any marketed product.

The FDA may withdraw approval if compliance with regulatory requirements and standards is not maintained or if problems occurafter the product reaches the market. Later discovery of previously unknown problems with a product, including adverse events of unanticipated severity or frequency, or with manufacturing processes, or failure to comply with regulatory requirements,may result in mandatory revisions to the approved labeling to add new safety information, imposition of post-market studies or clinical trials to assess new safety risks, or imposition of distribution or other restrictions under a REMS. Otherpotential consequences include, among other things:

 

  

restrictions on the marketing or manufacturing of the product, complete withdrawal of the product from themarket or product recalls;

 

  

safety alerts, Dear Healthcare Provider letters, press releases or other communications containing warnings orother safety information about the product;

 

  

mandated modification of promotional materials and labeling and issuance of corrective information;

 

  

fines, warning letters, or untitled letters;

 

  

holds on clinical trials;

 

  

refusal of the FDA to approve applications or supplements to approved applications, or suspension orrevocation of product approvals;

 

  

product seizure or detention, or refusal to permit the import or export of products;

 

  

injunctions or the imposition of civil or criminal penalties; and

 

  

consent decrees, corporate integrity agreements, debarment or exclusion from federal healthcare programs.

The FDA closely regulates the marketing, labeling, advertising and promotion of biologics. A companycan make only those claims relating to safety and efficacy, purity and potency that are approved by the FDA and in accordance with the provisions of the approved label. The FDA and other agencies actively enforce the laws and regulations prohibitingthe promotion of off-label uses. Failure to comply with these requirements can result in, among other things, adverse publicity, warning letters, corrective advertising and potential civil and criminal penalties. Physicians may prescribe legallyavailable products for uses that are not described in the product’s labeling and that differ from those tested by us and approved by the FDA. Such off-label uses are common across medical specialties. Physicians may believe that such off-labeluses are the best treatment for many patients in varied circumstances. The FDA does not regulate the behavior of physicians in their choice of treatments. The FDA does, however, restrict manufacturer’s communications on the subject of off-labeluse of their products.

Biosimilars and Reference Product Exclusivity

The ACA includes a subtitle called the Biologics Price Competition and Innovation Act (BPCIA), which created an abbreviatedapproval pathway for biological products that are biosimilar to or interchangeable with an

 

159


Table of Contents

FDA-licensed reference biological product. The FDA has issued several guidance documents outlining an approach to review and approval of biosimilars.Biosimilarity, which requires that there be no clinically meaningful differences between the biological product and the reference product in terms of safety, purity, and potency, can be shown through analytical studies, animal studies, and aclinical study or studies, unless the Secretary of Health and Human Services waives a required element. Interchangeability requires that a product is biosimilar to the reference product and the product must demonstrate that it can be expected toproduce the same clinical results as the reference product in any given patient and, for products that are administered multiple times to an individual, the biological product and the reference product may be alternated or switched after one hasbeen previously administered without increasing safety risks or risks of diminished efficacy relative to exclusive use of the reference product. Complexities associated with the larger, and often more complex, structures of biological products, aswell as the processes by which such products are manufactured, pose significant hurdles to approval of biosimilar and interchangeable biosimilar products.

A reference product is granted 12 years of exclusivity from the time of first licensure of the reference product, and anapplication for a biosimilar product may not be submitted to the FDA until four years following the date that the reference product was first licensed by the FDA. In addition, the approval of a biosimilar product may not be made effective by the FDAuntil 12 years from the date on which the reference product was first licensed. During this 12-year period of exclusivity, another company may still market a competing version of the reference product if theFDA approves a BLA for the competing product containing that sponsor’s own preclinical data and data from adequate and well-controlled clinical trials to demonstrate the safety, purity and potency of the other company’s product.

At this juncture, it is unclear whether products deemed “interchangeable” by the FDA will, in fact, be readilysubstituted by pharmacies, which are governed by state pharmacy law.

A biological product can also obtain pediatricmarket exclusivity in the United States. Pediatric exclusivity, if granted, adds six months to existing exclusivity periods and patent terms. This six-month exclusivity, which runs from the end of otherexclusivity protection or patent term, may be granted based on the voluntary completion of a pediatric study, requested by the Secretary, in accordance with an FDA-issued “Written Request” for such astudy. However, extensions are not applicable if made later than 9 months prior to the expiration of such period.

Other Regulatory Matters

As further described below, manufacturing, sales, commercialization and promotion of product candidates following productapproval and other related activities of the company, where applicable, are subject to regulation by numerous regulatory authorities in the United States in addition to the FDA, which may include the CMS, other divisions of the Department of Healthand Human Services (HHS), the Department of Justice, the Drug Enforcement Administration, the Consumer Product Safety Commission, the Federal Trade Commission, the Occupational Safety & Health Administration, the Environmental ProtectionAgency and state and local governments and governmental agencies.

Other Healthcare Laws

Physicians, other healthcare providers, and third-party payors will play a primary role in the recommendation and prescriptionof any products for which we obtain marketing approval. Our business operations and any current or future arrangements with third-party payors, healthcare providers and physicians may expose us to broadly applicable fraud and abuse and otherhealthcare laws and regulations that may constrain the business or financial arrangements and relationships through which we develop, market, sell and distribute any drugs for which we obtain marketing approval. In the United States, these lawsinclude, without limitation:

 

  

The federal Anti-Kickback Statute, an intent-based, federal criminal statute which prohibits, among otherthings, persons and entities from knowingly and willfully soliciting, offering, paying, receiving or providing

 

160


Table of Contents
 

any remuneration (including any kickback, bride, or rebate), directly or indirectly, overtly or covertly, in cash or in kind, to induce or reward, or in return for, either the referral of anindividual for, or the purchase, lease, order or recommendation of, any item or service, for which payment may be made, in whole or in part, under a federal healthcare program such as Medicare or Medicaid. A person or entity need not have actualknowledge of the federal Anti-Kickback Statute or specific intent to violate it in order to have committed a violation. The term remuneration has been interpreted broadly to include anything of value. Further, courts have found that if “onepurpose” of the remuneration is to induce referrals, the federal Anti-Kickback Statute is violated. Violations may be subject to significant civil and criminal fines and penalties for each violation, imprisonment, and exclusion fromparticipation in federal healthcare programs. The federal Anti-Kickback Statute applies to arrangements between pharmaceutical manufacturers on the one hand and individuals, such as prescribers, patients, purchasers, and formulary managers on theother hand, including, for example, consulting/speaking arrangements, discount and rebate offers, grants, charitable contributions, and patient support offerings, among others. Although there are a number of statutory exceptions and regulatory safeharbors to the federal Anti-Kickback Statute that protect certain common industry activities from prosecution, these exceptions and safe harbors are narrowly drawn and arrangements may be subject to scrutiny or penalty if they do not fully satisfyall elements of an available exception or safe harbor;

 

  

The federal civil and criminal false claims laws, including the civil False Claims Act (FCA), which prohibitindividuals or entities from, among other things, knowingly presenting, or causing to be presented, to the federal government, claims for payment or approval that are false, fictitious or fraudulent; knowingly making, using, or causing to be made orused, a false statement or record material to a false or fraudulent claim or obligation to pay or transmit money or property to the federal government; or knowingly concealing or knowingly and improperly avoiding or decreasing an obligation to paymoney to the federal government. Manufacturers can be held liable under the FCA even when they do not submit claims directly to government payors if they are deemed to “cause” the submission of false or fraudulent claims. In addition, thegovernment may assert that a claim that includes items or services resulting from a violation of the federal Anti-Kickback Statute, FDCA, or other law constitutes a false or fraudulent claim for purposes of the FCA. The FCA also permits a privateindividual acting as a “whistleblower” to bring qui tam actions on behalf of the federal government alleging violations of the FCA and to share in any monetary recovery or settlement. Violations of the FCA may be subject tosignificant civil fines and penalties for each false claim, treble damages, and potential exclusion from participation in federal healthcare programs;

 

  

The federal civil monetary penalties laws, which impose significant civil fines against individuals andentities that engage in activities including, among other things, (1) knowingly presenting, or causing to be presented, a claim for services not provided as claimed or that is otherwise false or fraudulent in any way, (2) arranging for orcontracting with an individual or entity that is excluded from participation in federal healthcare programs to provide items or services reimbursable by a federal healthcare program, (3) violations of the federal Anti-Kickback Statute,(4) failing to report and return a known overpayment, or (5) offering or transferring any remuneration to a Medicare or Medicaid beneficiary if the person knows or should know it is likely to influence the beneficiary’s selection of aparticular provider, practitioner, or supplier of items or services reimbursable by Medicare or Medicaid, unless an exception applies;

 

  

The federal criminal statutes enacted under HIPAA, which impose criminal liability for knowingly and willfullyexecuting, or attempting to execute, a scheme to defraud any healthcare benefit program, including private third-party payors, or obtain, by means of false or fraudulent pretenses, representations, or promises, any of the money or property owned by,or under the custody or control of, any healthcare benefit program; knowingly and willfully embezzling or stealing from a healthcare benefit program; willfully preventing, obstructing, misleading, or delaying a criminal investigation of a healthcareoffense; and knowingly and willfully falsifying, concealing or covering up a material fact or making any materially false statements in connection with the delivery of or payment for healthcare benefits, items or services. Similar to the federalAnti-Kickback Statute, a person or entity need not have actual knowledge of the statute or specific intent to violate it in order to have committed a violation;

HIPAA, as amended by HITECH, and their respective implementing regulations, imposes, among other things,specified requirements on covered entities and their business associates relating to the privacy and security of individually identifiable health information including mandatory contractual terms and required implementation of technical safeguardsof such information. HITECH also created new tiers of civil monetary penalties, amended HIPAA to make civil and criminal penalties directly applicable to business associates in some cases, and gave state attorneys general new authority to file civilactions for damages or injunctions in federal courts to enforce the federal HIPAA laws and seek attorneys’ fees and costs associated with pursuing federal civil actions;

 

  

The federal Physician Payments Sunshine Act, enacted as part of the ACA, which imposes annual reportingrequirements for certain manufacturers of drugs, devices, biologics, and medical supplies for which payment is available under Medicare, Medicaid, or the Children’s Health Insurance Program, for certain payments and “transfers ofvalue” provided to U.S.-licensed physicians (defined to include doctors, dentists, optometrists, podiatrists and chiropractors) and teaching hospitals, as well as ownership and investment interests held by physicians and their immediate familymembers. Effective January 1, 2022, these reporting obligations will extend to include transfers of value made in the previous year to certain non-physician providers, including physician assistants,nurse practitioners, clinical nurse specialists, certified registered nurse anesthetists, anesthesiology assistants, and certified nurse midwives; and

 

  

Analogous state and foreign laws and regulations, such as state anti-kickback and false claims laws, which mayapply to sales or marketing arrangements and claims involving healthcare items or services reimbursed by non-governmental third party-payors, including private insurers, and may be broader in scope than theirfederal equivalents; state and foreign laws requiring pharmaceutical companies to comply with the pharmaceutical industry’s voluntary compliance guidelines and the relevant compliance guidance promulgated by the federal government or otherwiserestrict payments that may be made to healthcare providers; state laws and regulations that require disclosures to state agencies and/or commercial purchasers with respect to certain price increases that exceed a certain level as identified in therelevant statutes; and state and foreign laws that require drug manufacturers to report information related to payments and other transfers of value to physicians and other healthcare providers, and restrict marketing practices or require disclosureof marketing expenditures and pricing information; state and local laws that require the registration of pharmaceutical sales representatives; and state and foreign laws that govern the privacy and security of health information in somecircumstances and which may differ from each other in significant ways and often are not pre-empted by HIPAA and may therefore complicate compliance efforts.

The full scope and enforcement of each of these laws is uncertain and subject to rapid change in the current environment ofhealthcare reform. Federal and state enforcement bodies have continued to increase their scrutiny of interactions between healthcare companies and healthcare providers, which has led to a number of investigations, prosecutions, convictions andsettlements in the healthcare industry. It is possible that governmental authorities will conclude that our business practices, including certain arrangements with physicians who receive stock, warrants, or stock options as compensation for servicesprovided to us, do not comply with current or future statutes, regulations or case law involving applicable fraud and abuse or other healthcare laws and regulations. If our operations are found to be in violation of any of these laws or any otherrelated governmental regulations that may apply to us, we may be subject to significant civil, criminal and administrative penalties, damages, fines, imprisonment, disgorgement, exclusion from government funded healthcare programs, such as Medicareand Medicaid, reputational harm, additional oversight and reporting obligations if we become subject to a corporate integrity agreement or similar settlement to resolve allegations of non-compliance with theselaws and the curtailment or restructuring of our operations. If any of the physicians or other healthcare providers or entities with whom we expect to do business is found to be not in compliance with applicable laws, they may be subject to similaractions, penalties and sanctions. Ensuring business arrangements comply with applicable healthcare laws, as well as responding to possible investigations by government authorities, can be time- and resource-consuming and can divert a company’sattention from its business.

Coverage and Reimbursement

In the United States and markets in other countries, patients who are prescribed treatments for their conditions and providersperforming the prescribed services generally rely on third-party payors to reimburse all or part of the associated healthcare costs. Patients and healthcare providers are unlikely to use our products unless third-party payor coverage is provided andreimbursement by such payor is adequate to cover a significant portion of the cost of our products. Significant uncertainty exists as to the coverage and reimbursement status of products approved by the FDA and other comparable governmentauthorities. Thus, even if a product candidate is approved, sales of the product will depend, in part, on the extent to which third-party payors, including government health programs in the United States such as Medicare and Medicaid,commercial health insurers and managed care organizations, provide coverage, and establish adequate reimbursement levels for, the product.

In the United States, no uniform policy of coverage and reimbursement for drug products exists among third-party payors.Therefore, coverage and reimbursement for drug products can differ significantly from payor to payor. The process for determining whether a third-party payor will provide coverage for a product may be separate from the process for setting the priceor reimbursement rate that the payor will pay for the product once coverage is approved. Third-party payors are increasingly challenging the prices charged, examining the medical necessity, and reviewing the cost-effectiveness of medical productsand services and imposing controls to manage costs. Third-party payors may limit coverage to specific products on an approved list, also known as a formulary, which might not include all of the approved products for a particular indication.Moreover, for products administered under the supervision of a physician, obtaining coverage and adequate reimbursement may be particularly difficult because of the higher prices often associated with such drugs. Additionally, separate reimbursementfor the product itself may or may not be available. Instead, the hospital or administering physician may be reimbursed only for providing the treatment or procedure in which our product is used.

In order to secure coverage and reimbursement for any product that might be approved for sale, a company may need to conductexpensive pharmacoeconomic studies in order to demonstrate the medical necessity and cost-effectiveness of the product, in addition to the costs required to obtain FDA or other comparable regulatory approvals. Obtaining coverage and reimbursementapproval of a product from a government or other third-party payor is a time-consuming and costly process that could require us to provide to each payor supporting scientific, clinical and cost-effectiveness data for the use of our products on a payor-by-payor basis, with no assurance that coverage and adequate reimbursement will be obtained. Nonetheless, product candidates may not be considered medically necessary orcost effective. A decision by a third-party payor not to cover a product could reduce physician utilization once the product is approved and have a material adverse effect on sales, our operations and financial condition. Additionally, a third-partypayor’s decision to provide coverage for a product does not imply that an adequate reimbursement rate will be approved. Further, one payor’s determination to provide coverage for a product does not assure that other payors will alsoprovide coverage and reimbursement for the product, and the level of coverage and reimbursement can differ significantly from payor to payor. Third-party coverage and reimbursement may not be available to enable us to maintain price levelssufficient to realize an appropriate return on our investment in product development.

In addition, prices for drugs maybe reduced by mandatory discounts or rebates required by federal healthcare programs (such as the Medicaid Drug Rebate Program and the 340B Drug Pricing Program) or discounts and rebates requested by private payors. In addition, any futurerelaxation of laws that presently restrict imports of drugs from countries where they may be sold at lower prices than in the United States may also impact the pricing of drugs. It is difficult to predict how Medicare coverage and reimbursementpolicies will be applied to products for which the company receives marketing approval in the future and coverage and reimbursement under different federal healthcare programs is not always consistent. Further, private payors often follow thecoverage and reimbursement policies established under Medicare. If reimbursement is not available or is available only at limited levels, we may not be able to successfully commercialize our products for which we receive marketing approval.

The containment of healthcare costs also has become a priority of federal, state and foreign governments, and the prices ofproducts have been a focus in this effort. Governments have shown significant interest in

implementing cost-containment programs, including price controls, restrictions on reimbursement and requirements for substitution of generic products. Adoption of price controls andcost-containment measures, and adoption of more restrictive policies in jurisdictions with existing controls and measures, could further limit a company’s revenue generated from the sale of any approved products. Coverage policies andthird-party payor reimbursement rates may change at any time. Even if favorable coverage and reimbursement status is attained for one or more products for which a company or its collaborators receive regulatory approval, less favorable coveragepolicies and reimbursement rates may be implemented in the future.

Healthcare Reform

In the United States and some foreign jurisdictions, there have been, and likely will continue to be, a number of legislativeand regulatory changes and proposed changes regarding the healthcare system directed at broadening the availability of healthcare, improving the quality of healthcare, and containing or lowering the cost of healthcare. For example, in March 2010,the United States Congress enacted the ACA, which, among other things, included changes to the coverage and payment for products under government health care programs. The ACA included provisions of importance to our potential product candidatethat:

 

  

created an annual, nondeductible fee on any entity that manufactures or imports specified branded prescriptiondrugs and biologic products, apportioned among these entities according to their market share in certain government healthcare programs;

 

  

expanded eligibility criteria for Medicaid programs by, among other things, allowing states to offer Medicaidcoverage to certain individuals with income at or below 138% of the federal poverty level, thereby potentially increasing a manufacturer’s Medicaid rebate liability;

 

  

expanded manufacturers’ rebate liability under the Medicaid Drug Rebate Program by increasing the minimumrebate for both branded and generic drugs and revising the definition of “average manufacturer price,” or AMP, for calculating and reporting Medicaid drug rebates on outpatient prescription drug prices;

 

  

addressed a new methodology by which rebates owed by manufacturers under the Medicaid Drug Rebate Program arecalculated for drugs that are inhaled, infused, instilled, implanted or injected;

 

  

expanded the types of entities eligible for the 340B drug discount program;

 

  

established the Medicare Part D coverage gap discount program by requiring manufacturers to provide point-of-sale-discounts off the negotiated price of applicable brand drugs to eligible beneficiaries during their coverage gap period as a condition for themanufacturers’ outpatient drugs to be covered under Medicare Part D; and

 

  

created a new Patient-Centered Outcomes Research Institute to oversee, identify priorities in, and conductcomparative clinical effectiveness research, along with funding for such research.

Since its enactment,there have been judicial, executive and Congressional challenges to certain aspects of the ACA. On June 17, 2021, the U.S. Supreme Court dismissed the most recent judicial challenge to the ACA brought by several states without specifically ruling onthe constitutionality of the ACA. Prior to the Supreme Court’s decision, President Biden issued an executive order to initiate a special enrollment period from February 15, 2021 through August 15, 2021 for purposes of obtaining healthinsurance coverage through the ACA marketplace. The executive order also instructed certain governmental agencies to review and reconsider their existing policies and rules that limit access to healthcare, including among others, reexaminingMedicaid demonstration projects and waiver programs that include work requirements, and policies that create unnecessary barriers to obtaining access to health insurance coverage through Medicaid or the ACA. It is unclear how other healthcare reformmeasures of the Biden administration or other efforts, if any, to challenge, repeal or replace the ACA will impact the ACA or our business.

Other legislative changes have been proposed and adopted in the United States since the ACA was enacted to reduce healthcareexpenditures. These changes include the Budget Control Act of 2011, which, among other

 

164


Table of Contents

things, included aggregate reductions of Medicare payments to providers of 2% per fiscal year, which went into effect in April 2013 and, due to subsequent legislative amendments to thestatute, will remain in effect through 2030 unless additional Congressional action is taken, with the exception of a temporary suspension by Congress of the 2% cut in Medicare payments from May 1, 2020 through December 31, 2021 due to the COVID-19 pandemic. In January 2013, the American Taxpayer Relief Act of 2012 was signed into law, which, among other things, further reduced Medicare payments to several providers, including hospitals, imagingcenters and cancer treatment centers, and increased the statute of limitations period for the government to recover overpayments to providers from three to five years.

Moreover, payment methodologies may be subject to changes under new healthcare legislation and regulatory initiatives. Forexample, CMS may develop new payment and delivery models, such as bundled payment models. In addition, recently there has been heightened governmental scrutiny over the manner in which manufacturers set prices for their commercial products, whichhas resulted in several Congressional inquiries and proposed and enacted state and federal legislation designed to, among other things, bring more transparency to product pricing, review the relationship between pricing and manufacturer patientprograms, and reform government program reimbursement methodologies for pharmaceutical products. For example, included in the Consolidated Appropriations Act, 2021 were several drug price reporting and transparency measures, such as a newrequirement for certain Medicare plans to develop tools to display Medicare Part D prescription drug benefit information in real time and for group and health insurance issuers to report information on pharmacy benefit and drug costs to theSecretaries of Health and Human Services, Labor and the Treasury. Any future measures will require authorization through additional legislation or regulation to become effective, and it is uncertain whether Congress or the new Biden administrationwill seek new legislative and/or administrative measures to control drug costs. At the state level, individual states in the United States have also increasingly passed legislation and implemented regulations designed to control pharmaceuticalproduct pricing, including price or patient reimbursement constraints, discounts, restrictions on certain product access and marketing cost disclosure and transparency measures, and, in some cases, designed to encourage importation from othercountries and bulk purchasing. The implementation of cost containment measures or other healthcare reforms may prevent us from being able to generate revenue, attain profitability, or commercialize any product that is ultimately approved, ifapproved.

On May 30, 2018, the Right to Try Act was signed into law. The law, among other things, provides a federalframework for certain patients to access certain investigational new drug products that have completed a Phase 1 clinical trial and that are undergoing investigation for FDA approval. Under certain circumstances, eligible patients can seek treatmentwithout enrolling in clinical trials and without obtaining FDA permission under the FDA expanded access program. There is no obligation for a drug manufacturer to make its drug products available to eligible patients as a result of the Right to TryAct, but the manufacturer must develop an internal policy and respond to patient requests according to that policy.

Outside the United States, ensuring coverage and adequate payment for a product also involves challenges. Pricing ofprescription pharmaceuticals is subject to government control in many countries. Pricing negotiations with government authorities can extend well beyond the receipt of regulatory approval for a product and may require a clinical trial that comparesthe cost-effectiveness of a product to other available therapies. The conduct of such a clinical trial could be expensive and result in delays in commercialization.

In the European Union, pricing and reimbursement schemes vary widely from country to country. Some countries provide thatproducts may be marketed only after a reimbursement price has been agreed. Some countries may require the completion of additional studies that compare the cost-effectiveness of a particular product candidate to currently available therapies or so-called health technology assessments, in order to obtain reimbursement or pricing approval. For example, the European Union provides options for its EU Member States to restrict the range of products for whichtheir national health insurance systems provide reimbursement and to control the prices of medicinal products for human use. EU Member States may approve a specific price for a product or it may instead adopt a system of direct or indirect controlson the profitability of the company placing

the product on the market. Other Member States allow companies to fix their own prices for products, but monitor and control prescription volumes and issue guidance to physicians to limitprescriptions. Recently, many countries in the European Union have increased the amount of discounts required on pharmaceuticals and these efforts could continue as countries attempt to manage healthcare expenditures, especially in light of thesevere fiscal and debt crises experienced by many countries in the European Union. The downward pressure on healthcare costs in general, particularly prescription products, has become intense. As a result, increasingly high barriers are beingerected to the entry of new products. Political, economic and regulatory developments may further complicate pricing negotiations, and pricing negotiations may continue after reimbursement has been obtained. Reference pricing used by various EUMember States, and parallel trade, i.e., arbitrage between low-priced and high-priced EU Member States, can further reduce prices. There can be no assurance that any country that has price controls orreimbursement limitations for pharmaceutical products will allow favorable reimbursement and pricing arrangements for any products, if approved in those countries.

Compliance with Other Federal and State Laws or Requirements; Changing Legal Requirements

If any products that we may develop are made available to authorized users of the Federal Supply Schedule of the GeneralServices Administration, additional laws and requirements apply. Products must meet applicable child-resistant packaging requirements under the U.S. Poison Prevention Packaging Act. Manufacturing, labeling, packaging, distribution, sales, promotionand other activities also are potentially subject to federal and state consumer protection and unfair competition laws, among other requirements to we may be subject.

Further, the distribution of pharmaceutical products is subject to additional requirements and regulations, includingextensive record-keeping, licensing, storage and security requirements intended to prevent the unauthorized sale of pharmaceutical products.

The failure to comply with any of these laws or regulatory requirements may subject us to possible legal or regulatory action.Depending on the circumstances, failure to meet applicable regulatory requirements can result in criminal prosecution, fines or other penalties, injunctions, exclusion from federal healthcare programs, requests for recall, seizure of products, totalor partial suspension of production, denial or withdrawal of product approvals, relabeling or repackaging, or refusal to allow a company to enter into supply contracts, including government contracts. Any claim or action against us for violation ofthese laws, even if we successfully defend against it, could cause us to incur significant legal expenses and divert our management’s attention from the operation of our business. Prohibitions or restrictions on marketing, sales or withdrawalof future products marketed by us could materially affect our business in an adverse way.

Changes in regulations,statutes or the interpretation of existing regulations could impact our business in the future by requiring, for example: (i) changes to our sales and manufacturing arrangements; (ii) additions or modifications to product labeling orpackaging; (iii) the recall or discontinuation of our products; or (iv) additional record-keeping requirements. If any such changes were to be imposed, they could adversely affect the operation of our business.

European Union Drug Development

In the EU, our future products also may be subject to extensive regulatory requirements. As in the United States, medicinalproducts can only be marketed if a Marketing Authorization (MA) from a competent regulatory authority has been obtained and additionally, the various phases of preclinical and clinical research in the EU are subject to significant regulatorycontrols.

European Union Clinical Trials

For example, in the EU a CTA must be submitted to each EU Member State’s competent authority and an independent ethicscommittee, similar to the FDA and the IRB, respectively. The CTA must include, among

 

166


Table of Contents

other things, a copy of the trial protocol and an investigational medicinal product dossier containing information about the manufacture and quality of the medicinal product under investigation.Once the CTA is approved by the EU Member State’s competent authority and the ethics committee has granted a positive opinion in relation to the conduct of the trial in the relevant Member State(s), in accordance with an EU Member State’srequirements, clinical trial development may proceed.

Clinical trials of medicinal products in the EU must be conductedin accordance with EU and EU Member State regulations and the International Conference on Harmonization, (ICH) guidelines on GCP, as well as the applicable regulatory requirements and the ethical principles that have their origin in the Declarationof Helsinki. Additional GCP guidelines from the European Commission, focusing in particular on traceability, apply to clinical trials of advanced therapy medicinal products. If the sponsor of the clinical trial is not established within the EU, itmust appoint an entity within the EU to act as its legal representative. The sponsor must take out a clinical trial insurance policy, and in most EU Member States, the sponsor is liable to provide ‘no fault’ compensation to any studysubject injured in the clinical trial.

Currently, CTAs must be submitted to the competent authority in each EU MemberState in which the trial will be conducted. Under the new Regulation on Clinical Trials, which is currently expected to take effect in January 2022, there will be a centralized application procedure where one EU Member State’s competentauthority takes the lead in reviewing the application and the other national authorities only have limited involvement. Any substantial changes to the trial protocol or other information submitted with the CTA must be notified to or approved by therelevant competent authorities and ethics committees. Medicines used in clinical trials must be manufactured in accordance with GMP. Other national and EU-wide regulatory requirements may also apply.

During the development of a medicinal product, EMA, and EU Member States’ competent authorities provide the opportunityfor dialogue and guidance on the development program. At the EMA level, this is usually done in the form of scientific advice, which is given by the CHMP. A fee is incurred with each scientific advice procedure. Advice from the EMA is typicallyprovided based on questions concerning, for example, quality (chemistry, manufacturing and controls testing), nonclinical testing and clinical trials, and pharmacovigilance plans and risk-management programs. Advice is not legally binding withregard to any future MA application (MAA) of the product concerned.

We are in the process of applying to renew our statuswith the EMA as a small and medium-sized enterprise (SME). If we are successful in maintaining our current SME status with the EMA, it will provide access to administrative, regulatory and financial support,including fee reductions for scientific advice and regulatory procedures.

European Union Drug Review and Approval

In the European Union, medicinal products can only be placed on the market after obtaining a MA. To obtain regulatory approvalof an investigational biological product in the EU, we must submit a MAA. The application used to file the BLA in the United States is similar to that required in the European Union, with the exception of, among other things, country-specificdocument requirements. The process for doing this depends, among other things, on the nature of the medicinal product.

The centralized procedure results in a single MA, issued by the European Commission, (based on the opinion of the EMA) whichis valid across the entire territory of the EU. The centralized procedure is compulsory for human drugs that are: (i) derived from biotechnology processes, such as genetic engineering, (ii) contain a new active substance indicated for thetreatment of certain diseases, such as HIV/AIDS, cancer, diabetes, neurodegenerative diseases, autoimmune and other immune dysfunctions and viral diseases, (iii) designated orphan medicines and (iv) advanced-therapy medicines, such as genetherapy, somatic cell therapy or tissue-engineered medicines. The centralized procedure may at the request of the applicant also be used in certain other cases. Therefore, the centralized procedure would be mandatory for the products we aredeveloping.

 

167


Table of Contents

The CAT, is responsible in conjunction with the CHMP for the evaluationATMPs. The CAT is primarily responsible for the scientific evaluation of ATMPs and prepares a draft opinion on the quality, safety and efficacy of each ATMP for which a MAA is submitted. The CAT’s opinion is taken into account by the CHMP whengiving its final recommendation regarding the authorization of a product in view of the balance of benefits and risks identified. Although the CAT’s draft opinion is submitted to the CHMP for final approval, the CHMP may depart from the draftopinion, if it provides detailed scientific justification. The CHMP and CAT are also responsible for providing guidelines on ATMPs and have published numerous guidelines, including specific guidelines on gene therapies and cell therapies. Theseguidelines provide additional guidance on the factors that the EMA will consider in relation to the development and evaluation of ATMPs and include, among other things, the preclinical studies required to characterize ATMPs; the manufacturing andcontrol information that should be submitted in a MAA; and post-approval measures required to monitor patients and evaluate the long term efficacy and potential adverse reactions of ATMPs.

Under the centralized procedure, the maximum timeframe for the evaluation of a MAA, by the EMA is 210 days. This excludes so-called clock stops, during which additional written or oral information is to be provided by the applicant in response to questions asked by the EMA. At the end of the review period, the EMA provides an opinionto the European Commission. If this opinion is favorable, the European Commission may then adopt a decision to grant an MA.

MAs have an initial duration of five years. After these five years, the authorization may be renewed on the basis of areevaluation of the risk-benefit balance. Once renewed, the MA is valid for an unlimited period unless the European Commission or the EU Member States’ competent authority decides, on justified grounds relating to pharmacovigilance, to proceedwith one additional five-year renewal.

In exceptional cases, the EMA might perform an accelerated review of an MAA in nomore than 150 days (not including clock stops). Innovative products that target an unmet medical need and are expected to be of major public health interest may be eligible for a number of expedited development and review programs, such as thePriority Medicines (PRIME) scheme, which provides incentives similar to the breakthrough therapy designation in the U.S. PRIME is a voluntary scheme aimed at enhancing the EMA’s support for the development of medicines that target unmet medicalneeds. It is based on increased interaction and early dialogue with companies developing promising medicines, to optimize their product development plans and speed up their evaluation to help them reach patients earlier. Product developers thatbenefit from PRIME designation can expect to be eligible for accelerated assessment but this is however not guaranteed. The benefits of a PRIME designation includes the appointment of a rapporteur from the EMA before submission of an MAA, earlydialogue and scientific advice at key development milestones, and the potential to qualify products for accelerated review earlier in the application process.

The European Commission may grant a so-called “conditional marketingauthorization” prior to obtaining the comprehensive clinical data required for an application for a full MA. Such conditional MAs may be granted for product candidates (including medicines designated as orphan medicinal products), if(i) the risk-benefit balance of the product candidate is positive, (ii) it is likely that the applicant will be in a position to provide the required comprehensive clinical trial data, (iii) the product fulfills an unmet medical needand (iv) the benefit to public health of the immediate availability on the market of the medicinal product concerned outweighs the risk inherent in the fact that additional data are still required. A conditional MA may contain specificobligations to be fulfilled by the MA holder, including obligations with respect to the completion of ongoing or new studies, and with respect to the collection of pharmacovigilance data. Conditional MAs are valid for one year, and may be renewedannually, if the risk-benefit balance remains positive, and after an assessment of the need for additional or modified conditions and/or specific obligations. The MA can be converted into a standard MA once the MA holder fulfils the obligations thatwere imposed and the complete data confirm that the medicine’s benefits continue to outweigh its risks. The timelines for the centralized procedure described above also apply with respect to the review by the EMA of applications for aconditional MA.

Table of Contents

The European Commission may also grant aso-called “marketing authorization under exceptional circumstances”. Such MA is intended for products for which the applicant can demonstrate that it is unable to provide comprehensive data on theefficacy and safety under normal conditions of use even after the product has been authorized, because the indications for which the product in question is intended are encountered so rarely that the applicant cannot reasonably be expected toprovide comprehensive evidence, or in the present state of scientific knowledge, comprehensive information cannot be provided, or it would be contrary to generally accepted principles of medical ethics to collect such information. Consequently, MAsunder exceptional circumstances may be granted subject to certain specific obligations, which may include the following:

 

  

the applicant must complete an identified program of studies within a time period specified by the competentauthority, the results of which form the basis of a reassessment of the benefit/risk profile;

 

  

the medicinal product in question may be supplied on medical prescription only and may in certain cases beadministered only under strict medical supervision, possibly in a hospital and in the case of a radio-pharmaceutical, by an authorized person; and

 

  

the package leaflet and any medical information must draw the attention of the medical practitioner to thefact that the particulars available concerning the medicinal product in question are as yet inadequate in certain specified respects.

A MA under exceptional circumstances is subject to annual review to reassess the risk-benefit balance in an annualreassessment procedure. Continuation of the authorization is linked to the annual reassessment and a negative assessment could potentially result in the MA being suspended or revoked. The renewal of a MA of a medicinal product under exceptionalcircumstances, however, follows the same rules as a “normal” MA. Thus, a MA under exceptional circumstances is granted for an initial five years, after which the authorization will become valid indefinitely, unless the EMA decides thatsafety grounds merit one additional five-year renewal. A MA under exceptional circumstances should not be granted when a conditional MA is more appropriate.

The European Union medicines rules expressly permit the EU Member States to adopt national legislation prohibiting orrestricting the sale, supply or use of any medicinal product containing, consisting of or derived from a specific type of human or animal cell, such as embryonic stem cells. While the products we have in development do not make use of embryonic stemcells, it is possible that the national laws in certain EU Member States may prohibit or restrict us from commercializing our products, even if they have been granted an MA.

European Union Data and Marketing Exclusivity

The EU also provides opportunities for market exclusivity. MAAs for generic medicinal products do not need to include theresults of preclinical and clinical trials, but instead can refer to the data included in the MA of a reference product for which regulatory data exclusivity has expired. Upon receiving MA, new chemical entities generally receive eight years of dataexclusivity and an additional two years of market exclusivity. If granted, data exclusivity prevents regulatory authorities in the European Union from referencing the innovator’s data to assess a generic or biosimilar application. During theadditional two-year period of market exclusivity, a generic marketing authorization can be submitted, and the innovator’s data may be referenced, but no generic or biosimilar product can be marketed untilthe expiration of the market exclusivity. The overall ten-year market exclusivity period may be extended to a maximum of eleven years if, during the first eight years a new therapeutic indication withsignificant clinical benefit over existing therapies is approved. However, there is no guarantee that a product will be considered by the EU regulatory authorities to be a new chemical entity, and products may not qualify for data exclusivity.

European Union orphan designation and exclusivity

Products receiving orphan designation in the EU can receive ten years of market exclusivity once they are authorized as orphanmedicines. During the ten-year market exclusivity period, the EMA cannot accept another

 

169


Table of Contents

application for a MA, or grant a MA or accept an application to extend an existing MA, for the same therapeutic indication, in respect of a similar medicinal product. An orphan medicinal productcan also obtain an additional two years of market exclusivity in the EU for pediatric studies. No extension to any supplementary protection certificate can be granted on the basis of pediatric studies for orphan indications.

The criteria for designating an “orphan medicinal product” in the EU are similar in principle to those in the UnitedStates. A medicinal product may be designated as orphan if (1) it is intended for the diagnosis, prevention or treatment of a life-threatening or chronically debilitating condition; (2) either (a) such condition affects no more thanfive in 10,000 persons in the European Union when the application is made, or (b) the product, without the benefits derived from orphan status, would not generate sufficient return in the European Union to justify investment; and (3) thereexists no satisfactory method of diagnosis, prevention or treatment of such condition authorized for marketing in the EU, or if such a method exists, the product will be of significant benefit to those affected by the condition. Orphan medicinalproducts are eligible for financial incentives such as reduction of fees or fee waivers. The application for orphan drug designation must be submitted before the MAA. The applicant will receive a fee reduction for the MAA if the orphan drugdesignation has been granted, but not if the designation is still pending at the time the MA is submitted. Orphan drug designation does not convey any advantage in, or shorten the duration of, the regulatory review and approval process.

The ten-year market exclusivity may be reduced to six years if, at the end of thefifth year, it is established that the product no longer meets the criteria for orphan designation, for example, if the product is sufficiently profitable not to justify maintenance of market exclusivity. Additionally, a MA may be granted to asimilar product for the same indication at any time if:

 

(1)

the second applicant can establish that its product, although similar, is safer, more effective or otherwiseclinically superior;

 

(2)

the holder of the MA for the original orphan medicinal product has given its consent to the secondapplicant; or

 

(3)

the holder of the MA for the original orphan medicinal product is unable to supply sufficient quantities ofthe medicinal product.

Post-Approval Requirements

Similar to the United States, both marketing authorization holders and manufacturers of medicinal products are subject tocomprehensive regulatory oversight by the EMA, the European Commission and/or the EU Member States’ competent authorities. The holder of a MA must establish and maintain a pharmacovigilance system and appoint an individual qualified person forpharmacovigilance who is responsible for oversight of that system. Key obligations include expedited reporting of suspected serious adverse reactions and submission of periodic safety update reports, (PSURs).

All new MAAs must include a RMP describing the risk management system that the company will put in place and documentingmeasures to prevent or minimize the risks associated with the product. The regulatory authorities may also impose specific obligations as a condition of the MA. Such risk-minimization measures or post-authorization obligations may include additionalsafety monitoring, more frequent submission of PSURs, or the conduct of additional clinical trials or post-authorization safety studies.

Failure to comply with EU and EU Member State laws that apply to the conduct of clinical trials, manufacturing approval, MAsof medicinal products and marketing of such products, both before and after grant of the MA; manufacturing of pharmaceutical products, statutory health insurance, bribery and anti-corruption or with other applicable regulatory requirements mayresult in administrative, civil or criminal penalties. These penalties could include delays or refusal to authorize the conduct of clinical trials or to grant MA, product withdrawals and recalls, product seizures, suspension, withdrawal or variationof the marketing authorization, total or partial suspension of production, distribution, manufacturing or clinical trials, operating restrictions, injunctions, suspension of licenses, fines and criminal penalties.

European Union Drug Marketing

The advertising and promotion of medicinal products is also subject to laws concerning promotion of medicinal products,interactions with physicians, misleading and comparative advertising and unfair commercial practices. All advertising and promotional activities for the product must be consistent with the approved summary of product characteristics, and thereforeall off-label promotion is prohibited. Direct-to-consumer advertising of prescription medicines is also prohibited in the EU.Although general requirements for advertising and promotion of medicinal products are established under EU Directives, the details are governed by regulations in each EU Member State and can differ from one country to another.

Much like the Anti-Kickback Statue prohibition in the United States, the provision of benefits or advantages to healthcareprofessionals to induce or encourage the prescription, recommendation, endorsement, purchase, supply, order or use of medicinal products is also prohibited in the EU. The provision of benefits or advantages to physicians is governed by the nationalanti-bribery rules of EU Member States. Infringement of these laws could result in substantial fines and imprisonment.

Payments made to healthcare professionals in certain EU Member States must be publicly disclosed. Moreover, agreements withhealthcare professionals often must be the subject of prior notification and approval by the healthcare professional’s employer, his or her competent professional organization and/or the regulatory authorities of the individual EU MemberStates. These requirements are provided in the national laws, industry codes or professional codes of conduct, applicable in the EU Member States. Failure to comply with these requirements could result in reputational risk, public reprimands,administrative or criminal penalties, including fines, or imprisonment.

Pricing and Reimbursement

Even if a medicinal product obtains a MA in the EU, there can be no assurance that reimbursement for such product will besecured on a timely basis or at all. Governments influence the price of medicinal products through their pricing and reimbursement rules and control of national healthcare systems that fund a large part of the cost of those products to consumers. EUMember States are free to restrict the range of pharmaceutical products for which their national health insurance systems provide reimbursement, and to control the prices and reimbursement levels of pharmaceutical products for human use. Somejurisdictions operate positive and negative list systems under which products may only be marketed once a reimbursement price has been agreed to by the government. EU Member States may approve a specific price or level of reimbursement for thepharmaceutical product, or alternatively adopt a system of direct or indirect controls on the profitability of the company responsible for placing the pharmaceutical product on the market, including volume-based arrangements, caps and referencepricing mechanisms. To obtain reimbursement or pricing approval, some of these countries may require the completion of clinical trials that compare the cost-effectiveness of a particular product candidate to currently available therapies. Other EUMember States allow companies to fix their own prices for medicines, but monitor and control company profits. The downward pressure on healthcare costs in general, particularly prescription medicines, has become very intense. As a result,increasingly high barriers are being erected to the entry of new products. In addition, in some countries, cross border imports from low-priced markets exert a commercial pressure on pricing within a country.

European Pediatric Investigation Plan

In the EU, MAAs for new medicinal products must generally include the results of studies conducted in the pediatric populationin compliance with a pediatric investigation plan (PIP) agreed with the EMA’s Pediatric Committee (PDCO). The PIP sets out the timing and measures proposed to generate data to support a pediatric indication of the drug for which an MA is beingsought. The PDCO can grant a deferral of the obligation to implement some or all of the measures of the PIP until there are sufficient data to demonstrate the efficacy and safety of the medicinal product in adults. Further, the obligation to providepediatric clinical trial data can be

waived by the PDCO when this data is not needed or appropriate because the product is likely to be ineffective or unsafe in children, the disease or condition for which the product is intendedoccurs only in adult populations, or when the product does not represent a significant therapeutic benefit over existing treatments for pediatric patients. Once the MA is obtained in all Member States of the EU and trial results are included in theproduct information, the product is eligible for six months’ supplementary protection certificate extension.

European DataCollection

The collection and use of personal data (including health data) in the EEA is governed by the EU GDPR andnational implementing legislation in EEA Member States. The EU GDPR applies to any company established in the EEA and to companies established outside the EEA that process personal data in connection with the offering of goods or services to datasubjects in the EEA or the monitoring of the behavior of data subjects in the EEA. The EU GDPR establishes stringent requirements applicable to the processing of personal data, including strict requirements relating to the validity of consent ofdata subjects, expanded disclosures about how personal data is used, requirements to conduct data protection impact assessments for “high risk” processing, limitations on retention of personal data, special provisions for “specialcategories of personal data” including health and genetic information of data subjects, mandatory data breach notification (in certain circumstances), “privacy by design” requirements, and direct obligations on service providersacting as processors. The EU GDPR also prohibits the international transfer of personal data from the EEA to countries outside of the EEA unless made to a country deemed to have adequate data privacy laws by the European Commission or a datatransfer mechanism has been put in place. Failure to comply with the requirements of the EU GDPR and the related national data protection laws of the EEA States may result in fines up to 20 million euros or 4% of a company’s global annualrevenues for the preceding financial year, whichever is higher. Moreover, the EU GDPR affords various data protection rights to individuals (e.g., the right to erasure of personal data) in certain circumstances, and the ability for data subjects toclaim material and non-material damages resulting from infringements of the EU GDPR. Given the breadth and depth of changes in data protection obligations, maintaining compliance with the EU GDPR, will requiresignificant time, resources and expense, and we may be required to put in place additional mechanisms ensuring compliance with the evolving data protection rules. This may be onerous and adversely affect our business, financial condition, results ofoperations and prospects. These requirements and risks are set out in further detail in the section of this prospectus titled “Risk Factors—Risks Related to Our Industry and Business Operations—We are subject to a variety of privacyand data security laws, and our failure to comply with them could harm our business.”

Rest of the WorldRegulation

For other countries outside of the EU (or in some cases, EEA) and the United States, such as the UnitedKingdom, countries in Eastern Europe, Latin America or Asia, the requirements governing the conduct of clinical trials, product licensing, pricing and reimbursement vary from country to country. Additionally, the clinical trials must be conducted inaccordance with GCP requirements and the applicable regulatory requirements and the ethical principles that have their origin in the Declaration of Helsinki.

If we fail to comply with applicable foreign regulatory requirements, we may be subject to, among other things, fines,suspension or withdrawal of regulatory approvals, product recalls, seizure of products, operating restrictions and criminal prosecution.

Employees andHuman Capital Resources

As of June 30, 2021, we had 19 full-time employees, seven of whom have Ph.D. or M.D. degrees.Of these full-time employees, 10 employees are engaged in research and development activities and one employee is engaged in finance, legal, human resources, facilities and general management. We have no collective bargaining agreements with ouremployees and we have not experienced any work stoppages. We consider our relationship with our employees to be good.

Table of Contents

Our human capital resources objectives include, as applicable, identifying,recruiting, retaining, incentivizing and integrating our employees. We also place a high value on the diversity of our team –including gender, background and expertise – to foster our culture of innovation. The principal purposes of ourequity incentive plans are to align the interests of our stockholders and those eligible for awards, to retain and incentivize officers, directors, employees, and other service providers, and to encourage them to act in our long-term best interests.We value our employees and regularly evaluate total compensation we provide, including pension contributions paid time off personal leave and other benefits, to ensure we remain competitive and attractive to potential new hires.

Facilities

We lease afacility containing approximately 302 square meters of office space for our main office, which is located at COBIS, Ole Maaloes Vej 3, 2200 Copenhagen N, Denmark. The lease expires on January 31, 2025. Our laboratory facility is located atMaersk Tower, Blegdamsvej 3, 2200 Copenhagen N, Denmark. The lease expires on August 31, 2021 and the terms for new facilities located in Copenhagen are under negotiation.

For our UK team, we lease an office facility located at 18 Maryport Street, Monmouthshire, UK. This lease can be terminated atour convenience.

We believe that our current facilities are adequate for our current needs and that suitable additionalor substitute space at commercially reasonable terms will be available as needed to accommodate any future expansion of our operations.

LegalProceedings

From time to time, we may be a party to litigation or subject to claims incident to the ordinary course ofbusiness. Although the results of litigation and claims cannot be predicted with certainty, we currently believe that the final outcome of these ordinary course matters will not have a material adverse effect on our business. Regardless of theoutcome, litigation can have an adverse impact on us because of defense and settlement costs, diversion of management resources and other factors. We are not currently a party to any material legal proceedings.

Corporate Governance

Classified Board of Directors

Upon the completion of this offering, our board of directors will consist of      members and be dividedinto three classes of directors that will serve staggered three-year terms. At each annual meeting of stockholders, a class of directors will be elected for a three-year term to succeed the same class whose term is then expiring. As a result, onlyone class of directors will be elected at each annual meeting of our stockholders, with the other classes continuing for the remainder of their respective three-year terms. Our directors will be divided among the three classes as follows:

 

  

the Class I directors will be             ,and their terms will expire at the first annual meeting of stockholders to be held after the completion of this offering;

 

  

the Class II directors will be             ,and their terms will expire at the second annual meeting of stockholders to be held after the completion of this offering; and

 

  

the Class III directors will be             ,and their terms will expire at the third annual meeting of stockholders to be held after the completion of this offering.

Each director’s term continues until the election and qualification of his or her successor, or his or her earlier death,resignation or removal. Our certificate of incorporation and bylaws to be in effect upon the

completion of this offering will authorize only our board of directors to fill vacancies on our board of directors. Any increase or decrease in the number of directors will be distributed amongthe three classes so that, as nearly as possible, each class will consist of one-third of the directors. This classification of our board of directors may have the effect of delaying orpreventing changes in control of our company. See the section titled “Description of Capital Stock—Anti-Takeover Provisions.”

Director Independence

In connection with this offering, we have applied to list our common stock on the Nasdaq Global Market. Under the rules ofNasdaq, independent directors must comprise a majority of a listed company’s board of directors within a specified period after the completion of this offering. In addition, the rules of Nasdaq require that, subject to specified exceptions,each member of a listed company’s audit, compensation and nominating and governance committees be independent. Under the rules of Nasdaq, a director will only qualify as an “independent director” if, in the opinion of thatcompany’s board of directors, that person does not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director.

Additionally, compensation committee members must not have a relationship with us that is material to the director’sability to be independent from management in connection with the duties of a compensation committee member.

Auditcommittee members must also satisfy the independence criteria set forth in Rule 10A-3 under the Exchange Act. In order to be considered independent for purposes ofRule 10A-3, a member of an audit committee of a listed company may not, other than in his or her capacity as a member of the audit committee, the board of directors or any other board committee:accept, directly or indirectly, any consulting, advisory or other compensatory fee from the listed company or any of its subsidiaries; or be an affiliated person of the listed company or any of its subsidiaries. We intend to satisfy the auditcommittee independence requirements of Rule 10A-3 as of the completion of this offering.

Our board of directors has undertaken a review of the independence of each director and considered whether each director has amaterial relationship with us that could compromise his or her ability to exercise independent judgment in carrying out his or her responsibilities. As a result of this review, our board of directors determined that, with the exception ofDr. Zocca, our Chief Executive Officer, each member of our board of directors is an “independent director” as defined under the applicable rules and regulations of the SEC and the listing requirements and rules of Nasdaq. In makingthese determinations, our board of directors reviewed and discussed information provided by the directors and by us with regard to each director’s business and personal activities and relationships as they may relate to us and our management,including the beneficial ownership of our common stock by each non-employee director and the transactions involving them described in the section titled “Certain Relationships and Related PartyTransactions.”

Board Committees

Our board of directors has established an audit committee, a compensation committee and a nominating and governance committeeprior to the completion of this offering, each of which will operate pursuant to a charter adopted by our board of directors and which will be effective prior to the consummation of this offering. The composition and responsibilities of each of thecommittees of our board of directors are described below. Members serve on these committees until their resignation or until otherwise determined by our board of directors. Our board of directors may establish other committees as it deems necessaryor appropriate from time to time. Following the completion of this offering, copies of the charters for each committee will be available on our website. Reference to our website does not constitute incorporation by reference of the informationcontained at or accessible through our website into this prospectus or the registration statement of which it forms a part.

Director Compensation

During 2020, members of our board of directors did not receive any retainer fees or other cash or equity-based compensation fortheir services as a director, other than reimbursements for out-of-pocket expenses incurred in connection with rendering such services, except for Ms. Glaub who receiveda retainer fee of $36,000 for services provided to us pursuant to a strategic advisor agreement.

Non-Employee Director Compensation Policy

In connection with the offering, we engaged Radford, an independent compensation consultant, to assist in theevaluation of our post-offering non-employee director compensation program. We expect to adopt a non-employee director compensation policy, as summarized below, which will become effective upon the pricing of this offering.

Annual Cash Compensation

Each non-employee director is entitled to receive annual cash compensation in the amounts summarized in the table below. Theseamounts are payable in equal quarterly installments, in arrears following the end of each quarter in which the service was performed, and are pro-rated for any partial months of service.

Expense Reimbursement

Our non-employee directors are also reimbursed for their reasonable out-of-pocket travel expenses to cover in-person attendanceat and participation in board of directors and committee meetings.

Limitations on Director and Officer Liability and Indemnification

Our amended and restated certificate of incorporation that will become effective in connection with this offering will containprovisions that will limit the liability of our directors for monetary damages to the fullest extent permitted by the DGCL. Consequently, our directors will not be personally liable to us or our stockholders for monetary damages for any breach offiduciary duties as directors, except liability for:

 

  

any breach of the director’s duty of loyalty to us or our stockholders;

 

  

any act or omission not in good faith or that involves intentional misconduct or a knowing violation of law;

 

  

unlawful payments of dividends or unlawful stock repurchases or redemptions as provided in Section 174 ofthe DGCL; or

 

181


Table of Contents
  

any transaction from which the director derived an improper personal benefit.

Our amended and restated certificate of incorporation and our bylaws that will become effective in connection with thisoffering will require us to indemnify our directors and officers, and allow us to indemnify other employees and agents, to the fullest extent permitted by the DGCL. Subject to certain limitations and limited exceptions, our amended and restatedcertificate of incorporation will also require us to advance expenses incurred by our directors and officers for the defense of any action for which indemnification is required or permitted.

We have entered into indemnification agreements with each of our directors and our executive officers. These agreements willprovide that we will indemnify each of our directors and such officers to the fullest extent permitted by law and our amended and restated certificate of incorporation.

We believe that these provisions in our amended and restated certificate of incorporation, bylaws and indemnificationagreements are necessary to attract and retain qualified persons such as directors, officers and key employees. We also maintain directors’ and officers’ liability insurance. The limitation of liability and indemnification provisions inour amended and restated certificate of incorporation and bylaws may discourage stockholders from bringing a lawsuit against our directors and officers for breaches of their fiduciary duties. They may also reduce the likelihood of derivativelitigation against our directors and officers, even though an action, if successful, might benefit us and other stockholders. Further, a stockholder’s investment may be adversely affected to the extent that we pay the costs of settlement anddamage awards against directors and officers as required by these indemnification provisions.

Role of the Board in Risk Oversight

One of the key functions of our board of directors is informed oversight of our risk management process. The board of directorsdoes not have a standing risk management committee, but rather administers this oversight function directly through the board of directors as a whole, as well as through its standing committees that address risks inherent in their respective areasof oversight. In particular, our board of directors is responsible for monitoring and assessing strategic risk exposure. Our audit committee has the responsibility to consider and discuss our major financial risk exposures and the steps ourmanagement has taken to monitor and control these exposures, including guidelines and policies to govern the process by which risk assessment and management is undertaken. The audit committee also monitors compliance with legal and regulatoryrequirements, in addition to oversight of the performance of our external audit function. Our nominating and corporate governance committee monitors the effectiveness of our corporate governance guidelines. Our compensation committee assesses andmonitors whether any of our compensation policies and programs has the potential to encourage excessive risk-taking.

EXECUTIVE COMPENSATION

The following is a discussion and analysis of compensation arrangements of our named executive officers. This discussioncontains forward-looking statements that are based on our current plans, considerations, expectations and determinations regarding future compensation programs. Actual compensation programs that we adopt may differ materially from currently plannedprograms as summarized in this discussion. As an “emerging growth company” as defined in the JOBS Act, we are not required to include a Compensation Discussion and Analysis section and have elected to comply with the scaled disclosurerequirements applicable to emerging growth companies.

Overview

Our current executive compensation program is intended to align executive compensation with our business objectives and toenable us to attract, retain and reward executive officers who contribute to our long-term success. The compensation paid or awarded to our executive officers is generally based on the assessment of each individual’s performance comparedagainst the business objectives established for the fiscal year as well as our historical compensation practices. In the case of new hire executive officers, their compensation is primarily determined based on the negotiations of the parties as wellas our historical compensation practices. For 2020, the material elements of our executive compensation program were base salary and annual cash bonuses.

This section provides a discussion of the compensation paid or awarded to our Chief Executive Officer and our two other mosthighly compensated executive officers as of December 31, 2020. We refer to these individuals as our “named executive officers.” For 2020, our named executive officers were:

 

  

Mai-Britt Zocca, Ph.D., Chief Executive Officer and Founder;

 

  

Eva Ehrnrooth, M.D., Ph.D., Chief Medical Officer; and

 

  

Mikkel Dybkjær, Former Chief Financial Officer (through May 1, 2021).*

 

 * 

Mr. Dybkjær transitioned from the role of Chief Financial Officer to the role of Vice President ofCorporate Finance, effective May 1, 2021.

We expect that our executive compensation program willevolve to reflect our status as a public company and market practices. In 2021, the board of directors engaged Radford, an independent compensation consultant, to assist it in its evaluation of our executive compensation program. In connection withsuch review, Radford recommended and the compensation committee of the board of directors approved compensation adjustments for Dr. Zocca and Dr. Ehrnrooth in order to bring their compensation further in line with relevant market data.Accordingly, effective upon the consummation of the offering, Dr. Zocca’s base salary and target bonus will equal $500,000 and 50% of base salary, respectively, while Dr. Ehrnrooth’s base salary and target bonus will equal$420,000 and 40% of base salary, respectively.

Compensation of Named Executive Officers

Base Salary. Base salaries are intended to provide a level of compensation sufficient to attract and retain an effectivemanagement team, when considered in combination with the other components of our executive compensation program. The relative levels of base salary for our named executive officers are designed to reflect each executive officer’s scope ofresponsibility and accountability with us. Please see the “Salary” column in the 2020 Summary Compensation Table for the base salary amounts earned by each named executive officer in 2020.

Annual Cash Bonuses. Historically, we have provided our senior leadership team with short-term incentivecompensation through our annual cash bonus plan. Annual bonus compensation holds executives accountable, rewards the executives based on actual business results and helps create a “pay for performance” culture. Our annual cash bonus planprovides cash incentive award opportunities for the achievement of performance goals established by our board of directors at the beginning of each fiscal year.

 

183


Table of Contents

The payment of awards under the 2020 annual cash bonus plan applicable tothe named executive officers was subject to the attainment of a number of goals relating to (i) financing (weighted 50%), (ii) clinical development (weighted 30%) and (iii) research & development (weighted 20%).

Early in 2020, the board of directors established target bonus opportunities for the participants in the annual bonus plan,including each of the named executive officers. The named executive officers had 2020 target bonus opportunities, as a percentage of base salary, as follows: Dr. Zocca, 25%; Dr. Ehrnrooth, 20%; and Mr. Dybkjær , 17%. Based onour 2020 performance, the board of directors awarded payouts under our annual cash bonus program in a total payout of 100% of the target bonus opportunity plus an additional discretionary bonus equal to 8% of base salary to select participants,including Drs. Zocca and Ehrnrooth. Please see the “Bonus” column in the 2020 Summary Compensation Table for the discretionary bonuses paid to the named executive officers with respect to 2020 and the“Non-Equity Incentive Compensation” column in the 2020 Summary Compensation Table for the amount of annual bonuses earned by the named executive officers in 2020 under the Company’s 2020 annualincentive program.

Warrants. To further align the interests of our executive officers with the interests of ourstockholders and to further focus our executive officers on our long-term performance, we have historically granted equity compensation in the form of warrants. Warrants operate in a manner similar to options in that the recipient is allowed toexercise the warrant and receive shares upon exercise, with the exercise price determined based on the fair market value of a share of common stock at the time of grant. The warrants granted to our named executive officers vested or will vest in 25%annual increments on December 31st of each year following the grant date, subject to the named executive officer’s continued service through the applicable vesting date. None of our named executive officers received warrant grants in 2020.Please see the “Outstanding Equity Awards at 2020 Fiscal Year-End” table for further information regarding the outstanding warrants held by our named executive officers as of December 31, 2020.In connection with the Corporate Reorganization, in exchange for each warrant to purchase an IO ApS class A share contributed by a holder, we will issue to such holder, a warrant to purchase a share of our Class A stock.

During 2021, our named executive officers received warrant grants in July 2021 with respect to the following number of shares:Dr. Zocca – 62,402; Dr. Ehrnrooth – 30,735; and Mr. Dybkjær – 3,350. The warrants vest based on the named executive officer’s continued employment through the applicable vesting date. Theexercise price of the warrants was determined based on a third-party valuation of the fair market value as of the date of grant. After the grant of the July 2021 warrants, we determined that the third-party valuation did not take into account theDanish charter provisions that treated an initial public offering event in a similar manner as a sale event and the impact of an initial public offering on the participating preferred stock and the issuance of common stock to the participatingpreferred stockholders as required pursuant to the Danish charter. As a result, the exercise price for the July 2021 warrants was set at a level in excess of fair market value at the time of grant. In recognition that the exercise price for the July2021 warrants was set at a significant premium to the actual fair market value on the date of grant, the compensation committee adjusted the exercise price of the unvested July 2021 warrants to reflect the updated independent third-party valuation,taking into account the impact of the initial public offering on the participating preferred stock. In accordance with Danish law, the compensation committee did not adjust the exercise price with respect to the vested portion of the July 2021grants, with such warrants having an exercise price in excess of the then-current fair market value. Additionally, our named executive officers received warrant grants in October 2021 with respect to the following number of shares:Dr. Zocca – 103,369; Dr. Ehrnrooth – 51,685; and Mr. Dybkjær – 5,169, with the per share exercise price determined based on a third-party valuation of our shares.

Equity Compensation Plans and Other Benefit Plans

2021 Equity and Incentive Plan

In connection with this offering, our board of directors expects to adopt, and our current stockholders expect to approve, the2021 Equity and Incentive Plan (the 2021 Plan) prior to the effective date of this offering.

The purposes of the 2021Plan are to align the interests of our stockholders and those eligible for awards, to retain and incentivize officers, directors, employees, and other service providers, and to encourage them to act in our long-term best interests. Our 2021 Planprovides for the grant of incentive stock options (within the meaning of Internal Revenue Code Section 422), nonstatutory stock options, stock appreciation rights, restricted stock, restricted stock units, other stock awards, and performanceawards.

The material terms of the 2021 Plan are expected to be as follows:

Eligibility. Officers, directors, employees, consultants, agents and independent contractors who provide services to usor to any subsidiary of ours are eligible to receive awards under the 2021 Plan.

Stock Subject to the 2021 Plan.The number of shares reserved for issuance under the 2021 Plan is            , plus an annual increase added on the first day of each fiscal year, beginning with the fiscal year endingDecember 31, 2022 and continuing until, and including, the fiscal year ending December 31, 2031. The annual increase will be equal to the lesser of (i)    % of the number of shares of common stock outstanding on thefirst day of such fiscal year or (ii) such other amount determined by our board of directors. To the extent an equity award granted under the 2021 Plan (other than any substitute award), expires or otherwise terminates without having beenexercised or paid in full, or is settled in cash, the shares subject to such award will become available for future grant under the 2021 Plan. In addition, to the extent shares subject to an award granted under the 2021 Plan are withheld to satisfya participant’s tax withholding obligation upon the exercise or settlement of such award (other than any substitute award) or to pay the exercise price of a stock option, such shares will become available for future grant under the 2021 Plan.

Plan Administration. Our compensation committee will administer the 2021 Plan. Our board of directors has theauthority to amend and modify the plan, subject to any stockholder approval required by applicable law or stock exchange rules. Subject to the terms of the 2021 Plan, our compensation committee will have the authority to determine the eligibilityfor awards and the terms, conditions, and restrictions, including vesting terms, the number of shares subject to an award, and any performance goals applicable to grants made under the 2021 Plan. The compensation committee also will have theauthority, subject to the terms of the 2021 Plan, to construe and interpret the 2021 Plan and awards, and amend outstanding awards at any time.

Stock Options and Stock Appreciation Rights. Our compensation committee may grant incentive stock options, nonstatutorystock options, and stock appreciation rights under the 2021 Plan, provided that incentive stock options are granted only to employees. Other than with respect to substitute awards, the exercise price of stock options and stock appreciation rightsunder the 2021 Plan will be fixed by the compensation committee, but must equal at least 100% of the fair market value of our common stock on the date of grant. The term of an option or stock appreciation right may not exceed ten years; provided,however, that an incentive stock option held by an employee who owns more than 10% of all of our classes of stock, or of certain of our affiliates, may not have a term in excess of five years, and must have an exercise price of at least 110% of thefair market value of our common stock on the grant date. Subject to the provisions of the 2021 Plan, the compensation committee will determine the remaining terms of the options and stock appreciation rights (e.g., vesting). Upon aparticipant’s termination of service, the participant may exercise his or her option or stock appreciation right, to the extent vested (unless the compensation committee permits otherwise), as specified in the award agreement.

Stock Awards. Our compensation committee will decide at the time of grant whether an award will be in the form ofrestricted stock, restricted stock units, or other stock award. The compensation committee will determine

 

187


Table of Contents

the number of shares subject to the award, vesting, and the nature of any performance measures. Unless otherwise specified in the award agreement, the recipient of restricted stock will havevoting rights and be entitled to receive dividends with respect to his or her shares of restricted stock. The recipient of restricted stock units will not have voting rights, but his or her award agreement may provide for the receipt of dividendequivalents. Our compensation committee may grant other stock awards that are based on or related to shares of our common stock, such as awards of shares of common stock granted as bonus and not subject to any vesting conditions, deferred stockunits, stock purchase rights, and shares of our common stock issued in lieu of our obligations to pay cash under any compensatory plan or arrangement.

Performance Awards. Our compensation committee will determine the value of any performance award, the vesting andnature of the performance measures, and whether the award is denominated or settled in cash or in shares of our common stock. The performance goals applicable to a particular award will be determined by our compensation committee at the time ofgrant.

Transferability of Awards. The 2021 Plan does not allow awards to be transferred other than by will or thelaws of inheritance following the participant’s death, and options may be exercised, during the lifetime of the participant, only by the participant. However, an award agreement may permit a participant to assign an award to a family member bygift or pursuant to a domestic relations order, or to a trust, family limited partnership or similar entity established for one of the participant’s family members. A participant may also designate a beneficiary who will receive outstandingawards upon the participant’s death.

Certain Adjustments. If any change is made in our common stock subjectto the 2021 Plan, or subject to any award agreement under the 2021 Plan, without the receipt of consideration by us, such as through a stock split, stock dividend, extraordinary distribution, recapitalization, combination of shares, exchange ofshares or other similar transaction, appropriate adjustments will be made in the number, class, and price of shares subject to each outstanding award and the numerical share limits contained in the plan.

Change in Control. Subject to the terms of the applicable award agreement, upon a “change in control” (asdefined in the 2021 Plan), our board of directors may, in its discretion, determine whether some or all outstanding options and stock appreciation rights will become exercisable in full or in part, whether the restriction period and performanceperiod applicable to some or all outstanding restricted stock awards and restricted stock unit awards will lapse in full or in part and whether the performance measures applicable to some or all outstanding awards will be deemed to be satisfied. Ourboard of directors may further require that shares of stock of the corporation resulting from such a change in control, or a parent corporation thereof, or other property be substituted for some or all of our shares of common stock subject to anoutstanding award and that any outstanding awards, in whole or in part, be surrendered to us by the holder and be immediately cancelled by us in exchange for a cash payment, shares of common stock of the corporation resulting from or succeeding us,other property or a combination of cash, such shares of stock or other property.

Clawback. Awards granted underthe 2021 Plan and any cash payment or shares of our common stock delivered pursuant to an award are subject to forfeiture, recovery, or other action pursuant to the applicable award agreement or any clawback or recoupment policy that we may adopt.

Plan Termination and Amendment. Our board of directors has the authority to amend, suspend, or terminate the 2021Plan, subject to any requirement of stockholder approval required by law or stock exchange rules. Our 2021 Plan will terminate on the ten-year anniversary of its approval by our board of directors, unless weterminate it earlier.

New Plan Benefits. The compensation committee has the discretion to grant awards under the2021 Plan, and therefore it is not possible at the time of filing of this prospectus to determine future awards that will be received by our named executive officers or others under the 2021 Plan. All officers, directors, employees, consultants,agents and independent contractors of the Company and its subsidiaries are eligible for consideration to participate in the 2021 Plan.

Our board of directors may authorize the issuance ofpreferred stock with voting or conversion rights that could adversely affect the voting power or other rights of the holders of our common stock.

Anti-Takeover Provisions

The provisions of the DGCL, our amended and restated certificate of incorporation and our bylaws to be in effect following thisoffering could have the effect of delaying, deferring or discouraging another person from acquiring control of our company. These provisions, which are summarized below, are expected to discourage certain types of coercive takeover practices andinadequate takeover bids and encourage persons seeking to acquire control of our company to first negotiate with our board of directors. We believe that the benefits of increased protection of our potential ability to negotiate with an unfriendly orunsolicited acquirer outweigh the disadvantages of discouraging a proposal to acquire us because negotiation of these proposals could result in an improvement of their terms.

Section 203 of the DGCL

We are subject to the provisions of Section 203 of the DGCL regulating corporate takeovers. In general, Section 203prohibits a publicly held Delaware corporation from engaging in a “business combination” with an “interested stockholder” for a three-year period following the date that this stockholder becomes an interested stockholder, unlessthe business combination is approved in a prescribed manner. Under Section 203, a business combination between a corporation and an interested stockholder is prohibited unless it satisfies one of the following conditions:

 

  

before the stockholder became interested, our board of directors approved either the business combination orthe transaction, which resulted in the stockholder becoming an interested stockholder;

 

  

upon consummation of the transaction, which resulted in the stockholder becoming an interested stockholder,the interested stockholder owned at least 85% of the voting stock of the corporation

outstanding at the time the transaction commenced, excluding for purposes of determining the voting stock outstanding, shares owned by persons who are directors and also officers, and employeestock plans in some instances, but not the outstanding voting stock owned by the interested stockholder; or

 

  

at or after the time the stockholder became interested, the business combination was approved by our board andauthorized at an annual or special meeting of the stockholders by the affirmative vote of at least two-thirds of the outstanding voting stock, which is not owned by the interested stockholder.

Section 203 defines a business combination to include:

 

  

any merger or consolidation involving the corporation and the interested stockholder;

 

  

any sale, transfer, lease, pledge or other disposition involving the interested stockholder of 10% or more ofthe assets of the corporation;

 

  

subject to exceptions, any transaction that results in the issuance of transfer by the corporation of anystock of the corporation to the interested stockholder;

Certificate of Incorporation and Bylaw Provisions

Our amended and restated certificate of incorporation and our bylaws will include a number of provisions that may have theeffect of deterring hostile takeovers, or delaying or preventing changes in control of our management team or changes in our board of directors or our governance or policy, including the following:

Board Vacancies

Our amended and restated certificate of incorporation and bylaws will authorize generally only our board of directors to fillvacant directorships resulting from any cause or created by the expansion of our board of directors. In addition, the number of directors constituting our board of directors may be set only by resolution adopted by a majority vote of our entireboard of directors. These provisions prevent a stockholder from increasing the size of our board of directors and gaining control of our board of directors by filling the resulting vacancies with its own nominees.

Classified Board

Our amended and restated certificate of incorporation and bylaws will provide that our board of directors is classified intothree classes of directors. The existence of a classified board of directors could delay a successful tender offeror from obtaining majority control of our board of directors, and the prospect of that delay might deter a potential offeror. See thesection titled “Management—Corporate Governance—Classified Board of Directors” for additional information.

Directors Removed Only for Cause

Our amended and restated certificate of incorporation will provide that stockholders may remove directors only for cause.

Table of Contents

Supermajority Requirements for Amendments of Our Amended and Restated Certificate ofIncorporation and Bylaws

Our amended and restated certificate of incorporation will further provide that theaffirmative vote of holders of at least two-thirds of the voting power of our outstanding common stock will be required to amend certain provisions of our amended and restated certificate of incorporation,including provisions relating to the classified board, the size of the board of directors, removal of directors, special meetings, actions by written consent and designation of our preferred stock. The affirmative vote of holders of at least two-thirds of the voting power of our outstanding common stock will be required to amend or repeal our bylaws, although our bylaws may be amended by a simple majority vote of our board of directors.

Stockholder Action; Special Meetings of Stockholders

Our amended and restated certificate of incorporation will provide that our stockholders may not take action by writtenconsent, but may only take action at annual or special meetings of our stockholders. As a result, holders of our capital stock would not be able to amend our bylaws or remove directors without holding a meeting of our stockholders called inaccordance with our bylaws. Our amended and restated certificate of incorporation and our bylaws will provide that special meetings of our stockholders may be called only by a majority of our board of directors, the chairperson of our board ofdirectors, our chief executive officer, our president or the lead independent director, thus prohibiting a stockholder from calling a special meeting. These provisions might delay the ability of our stockholders to force consideration of a proposalor for stockholders to take any action, including the removal of directors.

These provisions may preclude our stockholders from bringing matters beforeour annual meeting of stockholders or from making nominations for directors at our annual meeting of stockholders. We expect that these provisions might also discourage or deter a potential acquirer from conducting a solicitation of proxies to electthe acquirer’s own slate of directors or otherwise attempting to obtain control of our company.

No Cumulative Voting

The DGCL provides that stockholders are not entitled to the right to cumulate votes in the election of directors unless acorporation’s certificate of incorporation provides otherwise. Our amended and restated certificate of incorporation and bylaws will not provide for cumulative voting.

Issuance of Undesignated Preferred Stock

We anticipate that after the filing of our amended and restated certificate of incorporation, our board will have theauthority, without further action by the stockholders, to issue up to              shares of undesignated preferred stock with rights and preferences, including voting rights, designatedfrom time to time by our board of directors. The existence of authorized but unissued shares of preferred stock enables our board of directors to render more difficult or to discourage an attempt to obtain control of us by means of a merger, tenderoffer, proxy contest or otherwise.

Exclusive Forum

Our amended and restated certificate of incorporation will provide that, unless we consent in writing to the selection of analternative forum, to the fullest extent permitted by law, the sole and exclusive forum for (1) any derivative action or proceeding brought on our behalf under Delaware law, (2) any action asserting a claim of breach of a fiduciary dutyowed by any of our directors, officers or other employees to us or our stockholders, (3) any action arising pursuant to any provision of the Delaware General Corporation Law or our amended and restated certificate of incorporation or bylaws,(4) any other action asserting a claim that is governed by the internal affairs doctrine shall be the Court of Chancery of the State of Delaware (or, if the Court of Chancery does not have jurisdiction, the federal district court for theDistrict of Delaware) or (5) any other action asserting an “internal corporate claim,” as defined in Section 115 of the Delaware General Corporation Law, in all cases subject to the court having jurisdiction over indispensableparties named as defendants. These exclusive-forum provisions do not apply to claims under the Securities Act or the Exchange Act. Any person or entity purchasing or otherwise acquiring any interest in our securities shall be deemed to have noticeof and consented to this provision. Although we believe these provisions benefit us by providing increased consistency in the application of Delaware law for the specified types of actions and proceedings, the provisions may have the effect ofdiscouraging lawsuits against us or our directors and officers.

SHARES ELIGIBLE FOR FUTURE SALE

Prior to this offering, there has been no public market for our common stock, and we cannot predict the effect, if any, thatmarket sales of our common stock or the availability of our common stock for sale will have on the market price of our common stock prevailing from time to time. Future sales of our common stock in the public market, or the availability of suchshares for sale in the public market, could adversely affect market prices prevailing from time to time. As described below, only a limited number of our common stock will be available for sale shortly after this offering due to contractual andlegal restrictions on resale. Nevertheless, sales of our common stock in the public market after such restrictions lapse, or the perception that those sales may occur, could adversely affect the prevailing market price at such time and our abilityto raise equity capital in the future.

Following the completion of this offering, based on the number shares of ourcommon stock outstanding as of          , and assuming no exercise of outstanding warrants after such date, we will have a total of            sharesof common stock outstanding.

Of those outstanding shares,             shares of common stock sold in the offering will be freely tradeable, except that any shares purchased in this offering by our affiliates, as that term is defined in Rule 144under the Securities Act, would only be able to be sold in compliance with the Rule 144 limitations described below.

Theremaining outstanding common stock will be, and shares subject to outstanding warrants will be upon issuance, deemed “restricted securities” as defined in Rule 144 under the Securities Act. Restricted securities may be sold in the publicmarket only if they are registered or if they qualify for an exemption from registration under Rule 144 or Rule 701 under the Securities Act, which rules are summarized below. All of our executive officers, directors and holders of substantially allof our equity securities are subject to lock-up agreements under which they have agreed, subject to specific exceptions, not to sell any of our equity securities for 180 days following the date of thisprospectus. As a result of these agreements and subject to the provisions of Rule 144 or Rule 701, common stock will be available for sale in the public market as follows:

 

  

beginning on the date of this prospectus, all                shares of our common stock sold in this offering will be immediately available for sale in the public market; and

 

  

beginning 181 days after the date of this prospectus (subject to the terms of the lock-up and market standoff agreements described below),                 additional shares will become eligible for sale in the publicmarket, of which                 shares will be held by affiliates and subject to the volume and other restrictions of Rule 144, as described below.

Lock-Up Agreements

We, our directors and officers and holders of substantially all of our equity securities have agreed or will agree prior to theeffective date of the registration statement of which this prospectus is a part, subject to certain exceptions, not to offer, pledge sell, contract to sell, transfer, lend or otherwise dispose of, directly or indirectly, any shares of our commonstock or securities convertible into or exchangeable or exercisable for common stock, for 180 days after the date of this prospectus without first obtaining the written consent of Morgan Stanley & Co. LLC, Jefferies LLC and Cowen andCompany, LLC, on behalf of the underwriters. These agreements are described below under the section titled “Underwriting.”

Rule 144

In general, Rule 144 provides that once we have been subject to the public company reporting requirements of Section 13 orSection 15(d) of the Exchange Act for at least 90 days, a person who is not deemed to have been one of our affiliates for purposes of the Securities Act at any time during the 90 days preceding a sale and who has beneficially owned the commonstock proposed to be sold for at least six months is entitled to sell those shares without complying with the manner of sale, volume limitation or notice provisions of Rule 144, subject to

 

201


Table of Contents

compliance with the public information requirements of Rule 144. If such a person has beneficially owned the common stock proposed to be sold for at least one year, including the holding periodof any prior owner other than our affiliates, then that person would be entitled to sell those shares without complying with any of the requirements of Rule 144.

In general, Rule 144 provides that our affiliates or persons selling our common stock on behalf of our affiliates are entitledto sell upon expiration of the market standoff agreements and lock-up agreements described above, within any three-month period, a number of our common stock that does not exceed the greater of:

 

  

1% of the number of our common stock then outstanding, which will equal                shares immediately after the completion of this offering; or

 

  

the average weekly trading volume of our common stock during the four calendar weeks preceding the filing of anotice on Form 144 with respect to that sale.

Sales of our common stock made in reliance upon Rule 144by our affiliates or persons selling our common stock on behalf of our affiliates are also subject to certain manner of sale provisions and notice requirements and to the availability of current public information about us.

Rule 701

Rule 701generally allows a stockholder who purchased our common stock pursuant to a written compensatory plan or contract and who is not deemed to have been an affiliate of our company during the immediately preceding 90 days to sell these shares inreliance upon Rule 144, but without being required to comply with the public information, holding period, volume limitation or notice provisions of Rule 144. Rule 701 also permits affiliates of our company to sell their Rule 701 shares under Rule144 without complying with the holding period requirements of Rule 144. All holders of Rule 701 shares, however, are required to wait until 90 days after the date of this prospectus before selling those shares pursuant to Rule 701.

Registration Rights

Following the completion of this offering, the holders of an aggregate of                 shares of our common stock, or their permitted transferees, will be entitled to rights with respect to the registration of these shares under theSecurities Act. These shares are referred to as registrable securities. These rights are provided under the terms of our IRA, which registration rightsinclude                .

Registration Statement

We intend to file a registration statement on Form S-8 under the Securities Actpromptly after the effectiveness of this offering to register shares of our common stock subject to warrants outstanding, as well as stock options reserved for future issuance under our equity compensation plans. The registration statement on Form S-8 is expected to become effective immediately upon filing, and shares of our common stock covered by the registration statement will then become eligible for sale in the public market, subject to the Rule 144limitations applicable to affiliates, vesting restrictions and any applicable market standoff agreements and lock-up agreements. See the section titled “Executive Compensation—Equity CompensationPlans” for a description of our equity compensation plans.

MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES TO NON-U.S. HOLDERS OF OUR COMMON STOCK

The following is a summary of material U.S.federal income tax consequences of the ownership and disposition of shares of our common stock as of the date hereof. Except where noted, this summary deals only with common stock that was acquired for cash in this offering and that is held as acapital asset by a non-U.S. holder (as defined below). This summary is based upon provisions of the U.S. Internal Revenue Code of 1986, as amended (the Code), and regulations, rulings and administrativepronouncements of the U.S. Internal Revenue Service (the IRS) and judicial decisions, in each case as of the date hereof. Those authorities may be changed, perhaps retroactively, so as to result in U.S. federal income tax consequences different fromthose summarized below. We cannot assure you that a change in law will not alter significantly the tax considerations that we describe in this summary.

A “non-U.S. holder” means a beneficial owner of shares of our common stock(other than an entity treated as a partnership for U.S. federal income tax purposes) that is not, for U.S. federal income tax purposes, any of the following:

 

  

an individual who is a citizen or resident of the United States;

 

  

a corporation (or any other entity treated as a corporation for U.S. federal income tax purposes) created ororganized in or under the laws of the United States, any state thereof or the District of Columbia;

 

  

an estate the income of which is subject to U.S. federal income taxation regardless of its source; or

 

  

a trust if it (1) is subject to the primary supervision of a court within the United States and one ormore U.S. persons (as defined under the Code) have the authority to control all substantial decisions of the trust or (2) has a valid election in effect under applicable U.S. Treasury regulations to be treated as a U.S. person.

This summary does not address all aspects of U.S. federal income taxation that may be relevant to non-U.S. holders in light of their particular circumstances. In addition, this summary does not address the Medicare tax on certain net investment income, U.S. federal gift or estate tax laws, any state, local or non-U.S. tax laws or any tax treaties. This summary also does not address the U.S. federal income tax consequences applicable to non-U.S. holders that are subject to specialtreatment under the U.S. federal income tax laws, including (without limitation):

 

  

former citizens or long-term residents of the United States;

 

  

“qualified foreign pension funds,” or entities wholly owned by a “qualified foreign pensionfund”;

 

  

“controlled foreign corporations,” “passive foreign investment companies,” andcorporations that accumulate earnings to avoid U.S. federal income tax;

 

  

financial institutions, insurance companies, regulated investment companies, real estate investment trusts,mutual funds, broker-dealers, traders in securities or other persons that elect to use a mark-to-market method of accounting for their holdings in our common stock;

 

  

persons who hold our common stock as “qualified small business stock” within the meaning ofSection 1202 of the Code;

 

  

persons who hold our common stock as a position in a hedging transaction, “straddle,”“conversion transaction,” or other risk reduction transaction or integrated investment;

 

  

persons subject to special tax accounting rules as a result of any item of gross income with respect to ourcommon stock being taken into account in an applicable financial statement;

 

  

persons subject to the alternative minimum tax, and

Table of Contents
  

persons who acquired our common stock through warrants, stock options or in other compensatory transactions orpartnerships or other pass-through entities for U.S. federal income tax purposes.

If a partnership (orother entity or arrangement treated as a partnership for U.S. federal income tax purposes) holds shares of our common stock, the tax treatment of a partner will generally depend upon the status of the partner, the activities of the partnership andcertain determinations made at the partner level. Accordingly, partners in partnerships (including entities or arrangements treated as partnerships for U.S. federal income tax purposes) considering the purchase of our common stock should consulttheir tax advisors regarding the U.S. federal income tax considerations of the purchase, ownership and disposition of our common stock by such partnership.

THIS DISCUSSION IS FOR INFORMATIONAL PURPOSES ONLY AND IS NOT TAX ADVICE. PROSPECTIVE INVESTORS ARE ENCOURAGED TO CONSULTTHEIR TAX ADVISORS WITH RESPECT TO THE APPLICATION OF THE U.S. FEDERAL INCOME TAX LAWS TO THEIR PARTICULAR SITUATION, AS WELL AS ANY TAX CONSEQUENCES OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF OUR COMMON STOCK ARISING UNDER THE U.S. FEDERAL GIFTOR ESTATE TAX LAWS OR UNDER THE LAWS OF ANY STATE, LOCAL, NON-U.S. OR OTHER TAXING JURISDICTION OR UNDER ANY APPLICABLE TAX TREATY.

Distributions

Distributions of cash or property on our common stock will constitute dividends for U.S. federal income tax purposesto the extent paid from our current or accumulated earnings and profits, as determined under U.S. federal income tax principles. To the extent those distributions exceed our current and accumulated earnings and profits, the distributions will betreated as a nontaxable return of capital to the extent of the non-U.S. holder’s tax basis in our common stock and thereafter as capital gain from the sale or exchange of such common stock.Please read “—Sales or other Taxable Dispositions.”

Subject to the withholding rules discussed below under“—Backup Withholding and Information Reporting” and “—Additional Withholding Requirements under FATCA” and with respect to effectively connected dividends, any distribution made toa non-U.S. holder on our common stock generally will be subject to U.S. federal withholding tax at a rate of 30% of the gross amount of the distribution unless an applicable income tax treatyprovides for a lower rate. To receive the benefit of a reduced treaty rate, a non-U.S. holder must provide the applicable withholding agent with a properly executed IRSForm W-8BEN or IRS Form W-8BEN-E (or other applicable or successor form) certifying qualification for thereduced rate, and the non-U.S. holder will be required to update such forms and certifications from time to time as required by law.A non-U.S. holder eligible for a reduced rate of U.S. federal withholding tax pursuant to an applicable income tax treaty may be eligible to obtain a refund of any excess amounts withheld by timelyfiling an appropriate claim for refund with the IRS. If the non-U.S. holder holds our common stock through a financial institution or other agent acting onthe non-U.S. holder’s behalf, the non-U.S. holder will be required to provide appropriate documentation to the agent, which then will berequired to provide certification to us or our paying agent, either directly or through other intermediaries. Non-U.S. holders should consult their tax advisors regarding their entitlement tobenefits under an applicable income tax treaty.

If dividends paid toa non-U.S. holder are effectively connected with a trade or business conducted by the non-U.S. holder in the United States (and, if required by anapplicable income tax treaty, are treated as attributable to a permanent establishment maintained by the non-U.S. holder in the United States),the non-U.S. holder will be exempt from the U.S. federal withholding tax described above, provided the non-U.S. holder satisfies certaincertification requirements by providing the applicable withholding agent a properly executed IRS Form W-8ECI certifying eligibility for exemption, andthe non-U.S. holder will be required to update such forms and certifications from time to time as required by law. Any such effectively

 

204


Table of Contents

connected dividends generally will be taxed on a net income basis at the rates and in the manner generally applicable to U.S. persons (as defined under the Code). If the non-U.S. holder is a corporation for U.S. federal income tax purposes, it may also be subject to a branch profits tax at a 30% rate (or such lower rate as specified by an applicable income tax treaty)on its effectively connected earnings and profits (as adjusted for certain items), which will include effectively connected dividends. Non-U.S. holders should consult their tax advisors regarding anyapplicable income tax treaties that may provide for different rules.

Sales or Other Taxable Dispositions

Subject to the discussion below under “—Backup Withholding and Information Reporting”, any gain realized by a non-U.S. holder on the sale or other disposition of our common stock generally will not be subject to U.S. federal income tax unless:

 

  

the gain is effectively connected with a trade or business of thenon-U.S. holder in the United States (and, if required by an applicable income tax treaty, is attributable to a U.S. permanent establishment of the non-U.S. holder), inwhich case the non-U.S. holder will be subject to tax on the gain derived from the sale or other disposition on a net income tax basis at the U.S. federal income tax rates applicable to U.S. citizens,nonresident aliens or domestic corporations, as applicable. In addition, if any non-U.S. holder is a foreign corporation, such effectively connected gain may be subject to an additional branch profits tax at a30% rate (or such lower rate as may be specified by an applicable income tax treaty);

 

  

the non-U.S. holder is an individual who is present in the UnitedStates for 183 days or more in the taxable year of that disposition, and certain other conditions are met, in which case the non-U.S. holder will be subject to a 30% (or such lower rate as may be specified byan applicable income tax treaty) tax on the gain derived from the sale or other disposition, which gain may be offset by U.S. source capital losses even though the individual is not considered a resident of the United States; or

 

  

we are or have been a “United States real property holding corporation” for U.S. federal income taxpurposes (as described below) and certain other conditions are met.

Generally, a corporation is a“United States real property holding corporation” (USRPHC) if the fair market value of its U.S. real property interests equals or exceeds 50% of the sum of the fair market value of its worldwide real property interests and its other assetsused or held for use in a trade or business (all as determined for U.S. federal income tax purposes). We believe that we are not currently and will not become a USRPHC, and the remainder of this discussion assumes this is the case. If we are orbecome a USRPHC, however, so long as our common stock is regularly traded on an established securities market during the calendar year in which the sale or other disposition occurs, only a non-U.S. holder whoactually or constructively holds or held (at any time during the shorter of the five-year period preceding the date of disposition or the holder’s holding period) more than 5% of our common stock will be subject to U.S. federal income tax onthe sale or other disposition of our common stock.

Backup Withholding and Information Reporting

Any distributions paid to a non-U.S. holder must be reported annually to the IRS and tothe non-U.S. holder. Copies of these information returns may be made available to the tax authorities in the country in which the non-U.S. holder resides or isestablished. Distributions on our common stock made to a non-U.S. holder generally will not be subject to backup withholding if the non-U.S. holder establishes anexemption by properly certifying its non-U.S. status on an IRS Form W-8BEN, IRS FormW-8BEN-E or other applicable or successor form.

Payments of the proceeds from a sale or other disposition by a non-U.S. holder of ourcommon stock effected by or through the office of a broker generally will be subject to information reporting and backup

 

205


Table of Contents

withholding (currently at the rate of 24%) unless the non-U.S. holder establishes an exemption by properly certifying itsnon-U.S. status on an IRS Form W-8BEN, IRS Form W-8BEN-E or other applicable or successorform and certain other conditions are met. Information reporting and backup withholding generally will not apply to any payment of the proceeds from a sale or other disposition of our common stock effected outside the United States by a non-U.S. office of a broker. However, unless such broker has documentary evidence in its records that the holder is not a U.S. person and certain other conditions are met, or thenon-U.S. holder otherwise establishes an exemption, information reporting will apply to a payment of the proceeds of the disposition of our common stock effected outside the United States by such a broker ifit has certain relationships within the United States. Notwithstanding the foregoing, backup withholding and information reporting may apply if either we or our paying agent has actual knowledge, or reason to know, that the non-U.S. holder is a U.S. person who is not an exempt recipient under the Code and applicable U.S. Treasury regulations.

Non-U.S. holders should consult their tax advisors regarding the application of theinformation reporting and backup withholding rules to them. Copies of information returns may be made available to the tax authorities of the country in which the non-U.S. holder resides or is incorporatedunder the provisions of a specific treaty or agreement. Backup withholding is not an additional tax. Rather, the U.S. income tax liability (if any) of persons subject to backup withholding will be reduced by the amount of tax withheld. If backupwithholding results in an overpayment of taxes, a refund may be obtained, provided that the required information is timely furnished to the IRS.

Additional Withholding Requirements Under FATCA

Sections 1471 through 1474 of the Code, and the U.S. Treasury regulations and administrative guidance issued thereunder(FATCA), impose a 30% withholding tax on any dividends paid on our common stock if paid to a “foreign financial institution” or a “non-financial foreign entity” (each as defined in theCode) (including, in some cases, when such foreign financial institution or non-financial foreign entity is acting as an intermediary), unless (1) in the case of a foreign financial institution, suchinstitution enters into an agreement with the U.S. government to withhold on certain payments and to collect and provide to the U.S. tax authorities substantial information regarding U.S. account holders of such institution (which includes certainequity and debt holders of such institution, as well as certain account holders that are non-U.S. entities with U.S. owners); (2) in the case of a non-financial foreignentity, such entity certifies that it does not have any “substantial United States owners” (as defined in the Code) or provides the applicable withholding agent with a certification identifying the direct and indirect substantial UnitedStates owners of the entity (in either case, generally on an IRS Form W-8BEN-E) and provides certain information with respect to such United States owners; or(3) the foreign financial institution or non-financial foreign entity otherwise qualifies for an exemption from these rules and provides appropriate documentation (such as an IRS Form W-8BEN-E). The U.S. Treasury has issued proposed regulations providing that the withholding provisions under FATCA do not apply with respect to gross proceeds from a sale orother disposition of our common stock, which may be relied upon by taxpayers until final regulations are issued.

Undercertain circumstances, a non-U.S. holder may be eligible for refunds or credits of the withholding tax under FATCA. Foreign financial institutions located in jurisdictions that have an intergovernmentalagreement with the United States governing these rules may be subject to different rules. Under certain circumstances, a holder might be eligible for refunds or credits of such taxes. Non-U.S. holders shouldconsult their tax advisors regarding the possible implications of this legislation on their investment in our common stock and the entities through which they hold our common stock, including, without limitation, the process and deadlines formeeting the applicable requirements to prevent the imposition of the 30% withholding tax under FATCA.

INVESTORSCONSIDERING THE PURCHASE OF OUR COMMON STOCK SHOULD CONSULT THEIR OWN TAX ADVISORS REGARDING THE APPLICATION OF THE U.S. FEDERAL INCOME TAX LAWS TO THEIR PARTICULAR SITUATIONS AND THE APPLICABILITY AND EFFECT OF U.S. FEDERAL GIFT AND ESTATE TAX LAWSAND ANY STATE, LOCAL OR NON-U.S. TAX LAWS AND TAX TREATIES.

In order to facilitate the offering of the common stock, the underwriters may engage in transactionsthat stabilize, maintain or otherwise affect the price of the common stock. Specifically, the underwriters may sell more shares than they are obligated to purchase under the underwriting agreement, creating a short position. A short sale is coveredif the short position is no greater than the number of shares available for purchase by the underwriters under the over-allotment option. The underwriters can close out a covered short sale by exercising the over-allotment option or purchasingshares in the open market. In determining the source of shares to close out a covered short sale, the underwriters will consider, among other things, the open market price of shares compared to the price available under the over-allotment option.The underwriters may also sell shares in excess of the over-allotment option, creating a naked short position. The underwriters must close out any naked short position by purchasing shares in the open market. A naked short position is more likely tobe created if the underwriters are concerned that there may be downward pressure on the price of the common stock in the open market after pricing that could adversely affect investors who purchase in this offering. As an additional means offacilitating this offering, the underwriters may bid for, and purchase, shares of common stock in the open market to stabilize the price of the common stock. These activities may raise or maintain the market price of the common stock aboveindependent market levels or prevent or retard a decline in the market price of the common stock. The underwriters are not required to engage in these activities and may end any of these activities at any time.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and the Board of Directors of IO Biotech ApS

Opinion on the Financial Statements

Wehave audited the accompanying balance sheets of IO Biotech ApS (the Company) as of December 31, 2020 and 2019, the related statements of operations and comprehensive loss, convertible preference shares and stockholders’ deficit, andcash flows for each of the two years in the period ended December 31, 2020, and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all materialrespects, the financial position of the Company at December 31, 2020 and 2019, and the results of its operations and its cash flows for each of the two years in the period ended December 31, 2020, in conformity with U.S. generally acceptedaccounting principles.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on theCompany’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company inaccordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB and in accordance with auditing standards generally accepted in theUnited States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not requiredto have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressingan opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error orfraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accountingprinciples used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Wehave served as the Company’s auditor since 2015.

1. Description of Business, Organization and Liquidity

Business

IO Biotech ApS is a clinical-stage biotechnology company dedicated to the identification and development of disruptive immunetherapies for the treatment of cancer. As used in these financial statements, unless the context otherwise requires, references to the “Company”, “we,” “us,” and “our” refer to IO Biotech ApS. We wereincorporated in Denmark in December 2014. We are developing novel, immune-modulating cancer therapies based on our T-win technology platform.

Risks and Uncertainties

We are subject to risks common to companies in the biotechnology industry including, but not limited to, new technologicalinnovations, protection of proprietary technology, dependence on key personnel, compliance with government regulations and the need to obtain additional financing. Product candidates currently under development will require significant additionalresearch and development efforts, including extensive pre-clinical and clinical testing and regulatory approval, prior to commercialization. These efforts require significant amounts of additional capital,adequate personnel infrastructure and extensive compliance reporting capabilities.

Our product candidates are indevelopment. There can be no assurance that our research and development will be successfully completed, that adequate protection for our intellectual property will be obtained, that any products developed will obtain necessary government regulatoryapproval or that any approved products will be commercially viable. Even if our product development efforts are successful, it is uncertain when, if ever, we will generate significant revenue from product sales. We operate in an environment of rapidchange in technology and substantial competition from pharmaceutical and biotechnology companies. In addition, we are dependent upon the services of our employees and consultants.

Liquidity Considerations

Since inception, we have devoted substantially all our efforts to business planning, conducting research and development,recruiting management and technical staff, and raising capital. We have financed our operations primarily through the issuance of convertible preference shares and convertible notes.

Our continued discovery and development of its product candidates will require significant additional research and developmentefforts, including extensive preclinical and clinical testing and regulatory approval prior t commercialization These efforts require significant amounts of additional capital, adequate personnel and infrastructure and extensive compliance-reportingcapabilities. Even if product development efforts are successful, it is uncertain when, if ever, we will realize significant revenue from product sales.

As of December 31, 2020, we had an accumulated deficit of $38.4 million. We have incurred losses and negative cashflows from operations since inception, including net losses of $12.0 million and $10.7 million for the years ended December 31, 2020 and 2019, respectively. We expect that our operating losses and negative cash flows will continue forthe foreseeable future as we continue to develop our product candidates. We currently expect that our cash and cash equivalents of $3.4 million as of December 31, 2020 together with the proceeds on closings of the class C preferenceshares, for gross proceeds of $61.5 million in January 2021 and $4.2 million in March 2021 will be sufficient to fund our operating expenses and capital requirements for at least 12 months from the date the financial statements are issued.However, additional funding will be necessary to fund future discovery research, pre-clinical and clinical activities. We will seek additional funding through public financings, debt financings, collaborationagreements, strategic alliances and licensing arrangements. Although we have been successful in raising capital in the past, there is no assurance that we will be successful in obtaining such additional financing on terms acceptable to it, if atall, and we may not be able to enter into collaborations or other arrangements. If we are unable to obtain funding, we could be forced to delay, reduce or eliminate our research and development programs, product portfolio expansion orcommercialization efforts, which could adversely affect our business prospects, even our ability to continue operations.

Coronavirus Pandemic

In March 2020, the World Health Organization declared the COVID-19 outbreak a pandemic. In order to mitigate the spread ofCOVID-19, governments have imposed unprecedented restrictions on business operations, travel and gatherings, resulting in a global economic downturn and other adverse economic and societal impacts. The COVID-19 pandemic has also overwhelmed orotherwise led to changes in the operations of many healthcare facilities, including clinical trial sites. While we are considered an essential business under applicable regulations and continue to operate, the impacts of COVID-19 initially placedsignificant strain on our clinical trial sites, have raised concerns around monitoring patient safety, and resulted in changes to patient visit frequencies. We are continuing to work closely with our clinical partners and have taken steps asnecessary to adjust our protocols and timelines due to the impact of the COVID-19 pandemic. The COVID-19 pandemic and its impacts continue to evolve. We cannot predict the scope and severity of any further disruptions as a result of COVID-19 ortheir impacts on us, but business disruptions for us or any of the third parties with whom we engage, including the collaborators, contract organizations, third-party manufacturers, suppliers, clinical trial sites, regulators and other third partieswith whom we conduct business could materially and negatively impact our ability to conduct our business in the manner and on the timelines presently planned. The extent to which the COVID-19 pandemic may continue to impact our business andfinancial performance will depend on future developments, which are highly uncertain and cannot be predicted with confidence, including the scope and duration of the pandemic, the extent and effectiveness of government restrictions and otheractions, including relief measures, implemented to address the impact of the pandemic, and resulting economic impacts.

Theactual and perceived impact of the COVID-19 pandemic is changing daily, and its ultimate effect on our business cannot be predicted. As a result, there can be no assurance that we will not experienceadditional negative impacts associated with COVID-19, which could be significant. The COVID-19 pandemic may negatively impact our business, financial condition andresults of operations causing interruptions or delays in the Company’s programs and services.

2. Summary of Significant Accounting Policies

Basis of Presentation

The accompanying financial statements have been prepared in conformity with U.S. GAAP. Any reference in these notes toapplicable guidance is meant to refer to U.S. GAAP, as found in the Accounting Standards Codification, or ASC, and Accounting Standards Update, or ASU, of the Financial Accounting Standards Board, or FASB.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires us to make estimates and assumptions that affectcertain reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of expenses during the reporting periods. Significant items subject to suchestimates and assumptions include contract research accruals, stock-based compensation expense, the fair value of the Company’s class A ordinary shares, or ordinary shares, applied to measuring convertible notes and valuation of theCompany’s deferred tax assets. We base our estimates on historical experience and various other assumptions that we believe to be reasonable under the circumstances. Changes in estimates are recorded in the period in which they become known.Actual results could differ from those estimates.

Currency and Currency Translation

The financial statements are presented in U.S. dollars, our reporting currency. Our functional currency is the Euro.Adjustments that arise from exchange rate changes on transactions denominated in a currency other than the functional currency are included in other income and expense in the statements of operations. Assets and

 

F-8


Table of Contents

liabilities recorded in our Euro functional currency are translated into the U.S. dollar reporting currency at the exchange rate on the balance sheet date. Our expenses in the Euro functionalcurrency are translated into the U.S. dollar reporting currency at the average exchange rate prevailing during the year. Resulting translation adjustments are recorded to other comprehensive income (loss), or OCI.

Cash and Cash Equivalents

The Company considers all highly liquid investments with an original maturity of three months or less at the date of purchaseto be cash equivalents. At December 31, 2020 and 2019, we had no cash equivalents.

Concentrations of CreditRisk and Off-Balance Sheet Risk

We maintain our cash in bank deposit andchecking accounts that at times exceed insured limits. We have not experienced any losses in such accounts and believes it is not exposed to any significant credit risk.

Fair Value of Financial Instruments

Fair value is defined as the price we would receive to sell an investment in a timely transaction or pay to transfer aliability in a timely transaction with an independent buyer in the principal market, or in the absence of a principal market, the most advantageous market for the investment or liability. A framework is used for measuring fair value utilizing athree-tier hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowestpriority to unobservable inputs (Level 3).

The three levels of the fair value hierarchy are as follows:

Level 1—Unadjusted quoted prices in active markets that are accessible at the measurement date foridentical, unrestricted assets or liabilities;

Level 2—Quoted prices in markets that arenot considered to be active or financial instrument valuations for which all significant inputs are observable, either directly or indirectly; and

Level 3—Prices or valuations that require inputs that are both significant to the fair value measurementand unobservable.

Financial instruments are categorized in their entirety based on the lowest level of input that issignificant to the fair value measurement. The assessment of the significance of a particular input to the fair value measurement requires judgment and considers factors specific to the investment. To the extent that the valuation is based on modelsor inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised by us in determining fair value is greatest for instruments categorized inLevel 3.

We monitor the availability of inputs that are significant to the measurement of fair value to assess theappropriate categorization of financial instruments within the fair value hierarchy. Changes in economic conditions or model-based valuation techniques may require the transfer of financial instruments from one fair value level to another. In suchinstances, our policy is to recognize significant transfers between levels at the end of the reporting period. The significance of transfers between levels is evaluated based upon the nature of the financial instrument and size of the transferrelative to total net assets available for benefits.

Research and Development Expenses

Research and development costs are expensed as incurred. The Company’s research and development expenses consist primarilyof costs incurred for the development of its product candidates and include expenses incurred under agreements with contract manufacturing organizations, or CMOs, contract research organizations, or CROs, investigative sites and consultants toconduct clinical trials and preclinical and non-clinical studies, costs to acquire, develop and manufacture supplies for clinical trials and other studies, salaries and

Table of Contents

related costs, including stock-based compensation, depreciation and other allocated facility-related and overhead expenses and licensing fees and milestone payments incurred under productlicense agreements where no alternative future use exists.

We may obtain grants from public and private funds for itsresearch and development projects. The grant income for a given period is recognized as a cost reimbursement and is typically based on the time and the costs that the we have spent on the specific project during that period. During the years endedDecember 31, 2020 and 2019, we had active cost reimbursement grants with Innovation Fund Denmark. The grants provided partial reimbursement of employment-related costs related to two employees pursuant to Business Ph.D. and Businesspost-doctoral programs. For the years ended December 31, 2020 and 2019, research and development expenses in the statements of operations include $91,000 and $30,000, respectively, of grant income cost reimbursement. 

We have historically met the requirements to receive a tax credit in Denmark of up to 5.5 million Danish Kroner per yearfor losses resulting from research and development costs of up to 25 million Danish Kroner per year. The tax credit is reported as a reduction to research and development expense in the statements of operations. For the years endedDecember 31, 2020 and 2019, research and development expenses include refundable tax credits of $904,000 and $827,000 respectively.

Accrued Research and Development Costs

Substantial portions of our pre-clinical and clinical trials are performed bythird-party laboratories, medical centers, CMOs, CROs and other vendors. These vendors generally bill monthly for services performed, or bill based upon milestone achievement. For preclinical studies, we accrue expenses based upon estimatedpercentage of work completed and the contract milestones remaining. For clinical studies, expenses are accrued based upon the number of patients enrolled, the duration of the study and other investigative costs. We monitor patient enrollment, theprogress of clinical studies and related activities to the extent possible through internal reviews of data reported to us by the CROs, correspondence with the CROs and clinical site visits. Our estimates depend on the timeliness and accuracy of thedata provided by the CROs regarding the status of each program and total program spending. We periodically evaluate the estimates to determine if adjustments are necessary or appropriate based on information we receive.

Leases

We enter into lease agreements for office and laboratory facilities and accounts for them in accordance with ASC Topic 840,Leases. These leases are classified as operating leases. Rent expense is recognized on a straight-line basis over the term of the lease and, accordingly, we record the difference between cash rent payments and the recognition of rent expense as adeferred rent liability. Since our leases are all short-term in nature, no deferred rent liability has been recorded in the years ended December 31, 2020 and 2019. Incentives granted under our facilities leases, including allowances to fundleasehold improvements, are deferred and are recognized as adjustments to rental expense on a straight-line basis over the term of the lease. No incentives were recognized in the years ended December 31, 2020 and 2019.

Convertible Preference Shares

We classify convertible preference shares outside of stockholders’ deficit on our balance sheet as certain liquidationevents are not strictly within our control. We record the issuance of convertible preference shares at the issuance price less related issuance costs. We have not adjusted the carrying values of the convertible preferred stock to its liquidationpreference because of the uncertainty as to whether a deemed liquidation event may occur.

Equity-Based Compensation

Stock-based compensation expense related to stock warrants granted to employees, directors and non-employees is recognized based on the grant-date estimated fair values of the awards using the Black- Scholes option pricing model, or Black-Scholes. The value is recognized as expense ratably over the requisiteservice period, which is generally the vesting term of the award. We adjust the expense for actual forfeitures as they occur. Stock based compensation expense is classified in the accompanying statements of operations based on the function to whichthe related services are provided.

 

F-10


Table of Contents

The grant date fair value of our ordinary shares utilized in Black-Scholesis determined by our board of directors with the assistance of management. The grant date fair value of our ordinary shares is determined using valuation methodologies which utilize certain assumptions including probability weighting of events,volatility, time to liquidation, a risk-free interest rate and an assumption for a discount for lack of marketability. In determining the fair value of our ordinary shares, the methodologies used to estimate the enterprise value of the Company wereperformed using methodologies, approaches, and assumptions consistent with the AICPA TPA.

Income Taxes

Deferred income tax assets and liabilities arise from temporary differences associated with differences between the financialstatements and tax basis of assets and liabilities, as measured by the enacted tax rates, which are expected to be in effect when these differences reverse. Deferred tax assets and liabilities are classified as current or non-current, depending upon the classification of the asset or liabilities to which they relate. Deferred tax assets and liabilities not related to an asset or liability are classified as current or non-current depending on the periods in which the temporary differences are expected to reverse. Valuation allowances are established when necessary, to reduce deferred tax assets to the amount expected to berealized.

We have generated net losses since inception and accordingly has not recorded a provision for income taxes.

We follow the provisions of ASC 740-10, Uncertainty in Income Taxes, orASC 740-10. We have not recognized a liability as a result of the implementation of ASC 740-10. A reconciliation of the beginning and ending amount of unrecognizedtax benefits has not been provided since there is no unrecognized benefit since the date of adoption. We have not recognized interest expense or penalties as a result of the implementation of ASC 740-10. Ifthere were an unrecognized tax benefit, we would recognize interest accrued related to unrecognized tax benefits in interest expense and penalties in operating expenses.

We have identified Denmark as our major tax jurisdiction.

Net Loss Per Share

We calculate basic and diluted net loss per share attributable to ordinary shareholders in conformity with the two-class method required for participating securities. Our convertible preference shares are participating securities in Company distributions. The net loss attributable to ordinary shareholders is not allocated tothe convertible preference shares as the holders of convertible preference shares do not have a contractual obligation to share in losses. Cumulative dividends on preference shares are added to net loss to arrive at net loss available to ordinaryshareholders.

Under the two-class method, basic net loss per share attributableto ordinary shareholders is computed by dividing the net loss attributable to ordinary shareholders by the weighted average number of ordinary shares outstanding during the period, without consideration of potential dilutive securities. Diluted netloss per share is calculated by dividing net loss by the weighted average number of shares of ordinary shares and potential dilutive common share equivalents outstanding during the period if the effect is dilutive. Potentially dilutive securitiesinclude stock warrants and convertible preference shares. In all periods presented, the Company’s outstanding stock warrants and convertible preference shares were excluded from the calculation of diluted net loss per share because theireffects were anti-dilutive.

Segments

Operating segments are defined as components of an entity for which separate financial information is available and that isregularly reviewed by the chief operating decision maker, or CODM, in deciding how to allocate resources to an individual segment and in assessing performance. Our CODM is our chief executive officer. We have determined we operate in a singlesegment.

Other Comprehensive Income (loss)

Other comprehensive income (loss), or OCI, is defined as the change in equity of a business enterprise during a period fromtransactions and other events and circumstances from non-owner sources. Our OCI includes currency translation from the EURO, our functional currency, to the U.S. dollar, our reporting currency.

Emerging Growth Company Status

We are an emerging growth company, as defined in the Jumpstart Our Business Startups Act of 2012, or JOBS Act. Under theJOBS Act, emerging growth companies can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act, until such time as those standards apply to private companies. We have elected to use thisextended transition period for complying with new or revised accounting standards that have different effective dates for public and private companies until the earlier of the date that it (i) is no longer an emerging growth company or(ii) affirmatively and irrevocably opts out of the extended transition period provided in the JOBS Act. As a result, these financial statements may not be comparable to companies that comply with the new or revised accountingpronouncements as of public company effective dates.

Recently Issued Accounting Standards

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), as amended,with guidance regarding the accounting for and disclosure of leases. ASU 2016-02 requires lessees to recognize the liabilities related all leases, including operating leases, with a term greater than 12 monthson the balance sheet. This update also requires lessees and lessors to disclose key information about their leasing transactions. This standard is effective for annual reporting periods beginning after December 15, 2021, and interim periodswithin annual periods beginning after December 15, 2022. Early adoption is permitted. We are currently assessing the potential impact of adopting ASU 2016-02 on our financial statements and financialstatement disclosures.

In June 2016, the FASB issued Accounting Standards UpdateNo. 2016-13, Financial Instruments-Credit Losses: Measurement of Credit Losses on Financial Instruments. ASU 2016-13 requires measurement and recognitionof expected credit losses for financial assets. In April 2019, the FASB issued clarification to ASU 2016-13 within ASU 2019-04, CodificationImprovements to Topic 326, Financial Instruments-Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments, or ASU 2016-13. The guidance is effective for fiscalyears beginning after December 15, 2022. We are currently assessing the potential impact of adopting ASU 2016-13 on our financial statements and financial statement disclosures.

In December 2019, the FASB issued ASU 2019-12, Simplifying the Accounting forIncome Taxes, or ASU 2019-12. ASU 2019-12 eliminates certain exceptions related to the approach for intra-period tax allocation, the methodology for calculatingincome taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. It also clarifies and simplifies other aspects of the accounting for income taxes. This guidance is effective for fiscal years beginningafter December 15, 2021, and interim periods within fiscal years beginning after December 15, 2022. Early adoption is permitted. We are currently assessing the impact adoption of ASU 2019-12 willhave on our financial statements and disclosures.

In August 2020, the FASB issued ASUNo. 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging Contracts in Entity s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity. ASU 2020-06 will simplify the accounting for convertible instruments byreducing the number of accounting models for convertible debt instruments and convertible preferred stock. Limiting the accounting models results in fewer embedded conversion features being separately recognized from the host contractas compared with current GAAP. Convertible instruments that continue to be subject to separation models are (i) those with embedded conversion features that are not clearly and closely related to the host contract, that meet thedefinition of a derivative, and that do not qualify for a scope

exception from derivative accounting and (ii) convertible debt instruments issued with substantial premiums for which the premiums are recorded aspaid-in capital. ASU 2020-06 also amends the guidance for the derivatives scope exception for contracts in an entity’s own equity to reduceform-over-substance-based accounting conclusions. ASU 2020-06 will be effective for us beginning after December 15, 2023. Early adoption is permitted, but no earlier than fiscal yearsbeginning after December 15, 2020, including interim periods within those fiscal years. We are currently assessing the impact adoption of ASU 2020-06 will have on our financial statementsand disclosures.

Valuation techniques used to measure fair value maximize the use of relevant observable inputsand minimize the use of unobservable inputs. Our convertible notes are classified within Level 3 of the fair value hierarchy because the fair value measurement is based, in part, on significant inputs not observed in the market.

In July 2019, we issued convertible notes to existing related party investors for proceeds of $9.0 million. Uponissuance, we elected the fair value option to account for the convertible notes, with any subsequent changes in fair value being recognized through the statements of operations as other income (expense) until the convertible notes are settled.We have not recorded interest expense separate from those fair value adjustments.

The convertible notes accrued interestat 8% per year beginning in August 2019 payable in cash or, at the investor’s discretion, into our class B or class C preference shares. In April 2020, the convertible notes plus accrued interest of $0.5 million, were converted accordingto the terms of the convertible notes into 142,437 shares of class B preference shares (Note 8).

We determinefair value of the convertible notes on issuance and at December 31, 2019 using a scenario-based valuation method and a Monte Carlo simulation model with inputs based on certain subjective assumptions, including (a) estimated conversiondates, (b) expected stock price volatility, (c) a risk-free interest

rates, and (d) implied debt yields. This approach results in the classification of these securities as Level 3 of the fair value hierarchy. The assumptions utilized to value theconvertible notes were as follows:

 

   December 31,
2019
  On Issuance
July 2019
 

Term (years)

   0.3   0.8 

Annual volatility

   86.1  77.1

Risk-free rate

   1.6  2.0

Debt yield

   50.0  50.0

On conversion in April 2020, we determined the fair value of the convertible notes withreference to the class B preference shares (Note 8) into which the convertible notes were converted into (142,437).

Therewere no transfers among Level 1, Level 2 or Level 3 categories in the years ended December 31, 2020 or 2019.

4. License andCollaboration Agreements

In February 2018, we entered into a clinical collaboration with MSDIG, to evaluate IO102 incombination with KEYTRUDA® (pembrolizumab) in first-line treatment of patients with metastatic non-small cell lung cancer. Under the terms of thecollaboration with MSDIG, we will conduct an international Phase 1/2 study to evaluate a combination therapy of IO102 and KEYTRUDA®. We will sponsor the clinical trials and MSDIG will provideKEYTRUDA® to be used in the clinical trials free of charge. We and MSDIG will be responsible for our own internal costs and expenses to support the study and we shall bear all other costsassociated with conducting the study, including costs of providing IO102 for use in the study. The rights to the data from the clinical trials will be shared by us and MSDIG and we will maintain global commercial rights to IO102.

7. Commitments and Contingencies

Lease Commitments

We have two operating leases in Copenhagen, Denmark for office space that expires in August 2021 and December 2021,respectively. Our leases have terms of one year or less. Rent expense for years ended December 31, 2020 and 2019 was $202,000 and $148,000 respectively.

In March 2021, we entered into a new lease for our office space in Copenhagen, Denmark that expires in January 2025,terminable upon three months’ notice.

Legal Proceedings

From time to time, we may be party to litigation arising in the ordinary course of its business. We were not subject to anymaterial legal proceedings during the years ended December 31, 2020 and 2019, and, to our knowledge, no material legal proceedings are currently pending or threatened.

Indemnification Agreements

We enter into certain types of contracts that contingently requires us to indemnify various parties against claims from thirdparties. These contracts primarily relate to procurement, service, consultancy or license agreements under which we may be required to indemnify vendors, service providers or licensees for certain claims, including claims that may be brought againstthem arising from our acts or omissions with respect to our products, technology, intellectual property or services.

Fromtime to time, we may receive indemnification claims under these contracts in the normal course of business. In the event that one or more of these matters were to result in a claim against us, an adverse outcome, including a judgment or settlement,may cause a material adverse effect on our future business, operating results or financial condition. It is not possible to estimate the maximum amount potentially payable under these contracts since we have no history of prior indemnificationclaims and the unique facts and circumstances involved in each particular claim will be determinative.

8. Convertible Preference Shares

As of December 31, 2020 and 2019, we had 584,583 and 366,301 class B preference shares, respectively, authorized,issued and outstanding.

Sales and Issuances of Preference Shares During the Years Ended December 31, 2020 and2019

In April 2020, we issued 142,437 class B preference shares at a subscription price of $64.48 per share toexisting related-party investors upon the conversion of convertible notes (Note 3). We recorded the 142,437 class B preference shares at fair value of $10.3 million ($72.15 per share) determined using an option pricing model, or OPM, assuming aCompany equity value of $40.6 million, a term of 1.6 years, volatility of 86.0% and a risk-free rate of 0.18%. We incurred issuance costs of $4,000 in connection with the issuances of the class B preference shares on conversion of theconvertible notes.

In July 2020, we issued 75,845 class B preference shares to existing related-party investors at asubscription price of $67.46 per share for gross cash proceeds of $5.1 million. We recorded the 75,845 class B preference shares at fair value of $5.6 million ($73.60 per share), resulting in a deemed dividend of $0.5 million recordedagainst additional paid-in capital on our balance sheet. Fair value of the class B preference shares issued on this date was determined using an OPM methodology assuming a Company equity value of$47.6 million, a term of 1.36 years, volatility of 92.4% and a risk-free rate of 0.16%. We incurred issuance costs of $10,000 in connection with the issuances of the class B preference shares.

Table of Contents

Issuances of Preference Shares Subsequent to December 31, 2020

In January 2021, we completed an investment agreement, Class C Investment Agreement, for the sale andissuance of up to 1,263,804 class C preference shares to new investors and existing related-party investors at a subscription price of $121.55 per share. Then, pursuant to the Class C Investment Agreement, we issued 505,520 class C preferenceshares for gross cash proceeds of $61.5. The Class C Investment Agreement further provides for a milestone closing in the event of certain development milestones before April 2022, whereby purchasers of class C preference shares are obligatedto a further subscription amount of $92.2 million, which, depending upon the outcome of certain of our activities, may result in a further issuance of 758,284 class C preference shares at a subscription price of $121.55 per share or 689,349class C preference shares at a subscription price of $134.62 per share. We incurred issuance costs of $340,000 in connection with the issuances of the class B preference shares.

In March 2021, prior to a milestone closing, an investor elected to purchase and we issued 35,825 class C preference sharesfor gross cash proceeds of $4.2 million pursuant to the Class C Investment Agreement.

Preferences,Privileges and Rights

Our class C preference shares and our class B preference shares together constitute ourpreferred classes of stock, or Preference Shares. Our Preference Shares have the following rights, preferences, privileges and restrictions:

Liquidity Preference

Company liquidity events, or Liquidity Events, include assignment or transfer of all or part of the shares from ourshareholders as a whole, listing of our shares, merger, demerger, liquidation or other dissolution of the Company, payment of dividends, reduction of our share capital for distribution to shareholders. In the case of a Liquidity Event, cash andproperty proceeds shall be distributed to our shareholders in accordance with the following priority:

 

 (i) 

First, the holders of class C preference shares, in preference to holders of class B preference shares andclass A ordinary shares, the subscription price paid and 8% per year interest on the subscription price paid from the date of payment of the subscription price until the date of allocation of proceeds, provided that where the available proceeds areinsufficient to make payment in full on the class C preference shares, then the available proceeds shall be allocated pro rata among the holders in proportion to their holdings of class C preference shares;

 

 (ii) 

Second, the holders of class B preference in preference to holders of class A ordinary shares, on any proceedsremaining after payment of proceeds to the holders of class C preference shares the subscription price paid and 8% per year interest on the subscription price paid from the date of payment of the subscription price until the date of allocation ofproceeds, provided that where the available proceeds are insufficient to make payment in full on the class B preference shares, then the available proceeds shall be allocated pro rata among the holders in proportion to their holdings of class Bpreference shares.

Distribution preferences pursuant to (i) and (ii) above, together the LiquidityPreference.

Conversion Option

Our Preference Shares are convertible at the option of the holder at any time on a one-for-one basis into our class A ordinary shares.

 

F-16


Table of Contents

Voting Rights and Board Representation

The holders of Preference Shares are entitled to one vote per share on all matters to be voted upon at all shareholder meetingsand written actions in lieu of meetings. The holders of Preference Shares are entitled to elect six of the eight directors on our board.

Anti-Dilution Protection

In the event we issue any additional shares for a consideration per share that is less than the applicable subscription pricepaid for the Preference Shares, the subscription price of the applicable Preference Shares (as adjusted for share splits, payment of dividends, recapitalization, consolidations of shares and similar events) for existing shareholders who participatein the purchase of such additional shares shall be adjusted on a weighted average basis. The adjustment shall be made through the issuance of new Preference Shares of the relevant class to the Preference Shareholders at quota value.

Redemption

Preference Shares are not subject to mandatory redemption. Upon certain change in control events that are outside of ourcontrol, including liquidation, sale or transfer of control of the Company, the Preference Shares are contingently redeemable.

9. Ordinary Shares

As of December 31, 2020, we had 50,000 shares of class A ordinary shares authorized, issued and outstanding.

The holders of class A ordinary shares are entitled to an allocation and distribution of proceeds in a Liquidity Event subjectto the Liquidation Preference. When the Liquidity Preference has been paid in full, any remaining proceeds shall be allocated pro rata to all shares in the Company.

The holders of class A ordinary shares are entitled to one vote per share on all matters to be voted upon at all shareholdermeetings and written actions in lieu of meetings. Together, as a single class with holders of Preference Shares, holders of class A ordinary shares may appoint two independent directors of our board.

10. Equity-Based Compensation

Employee Equity Plan

We may award up to 70,509 warrants. Each vested warrant will entitle the warrant holder to a single class A ordinary share.Holders of stock warrants are entitled to exercise the vested portion of the stock warrant. Stock warrants generally vest over a three-year period and expire five years from the vest date.

At December 31, 2020, we had 45,130 warrants available for future grant under our employee equity plan. There were nogrants, exercises, or forfeitures of any stock warrants during the years ended December 31, 2020 or 2019, and we did not recognize any tax benefits for stock-based compensation during the years ended December 31, 2020 or 2019.

Equity-Based Compensation

All share-based awards granted are measured based on the fair value on the date of the grant and compensation expense isrecognized with respect to those awards over the requisite service period, which is generally the vesting period of the respective award. Forfeitures related to equity-based compensation awards are recognized as they occur, and we reverse anypreviously recognized compensation cost associated with forfeited awards in the period the forfeiture occurs.

Equity-based compensation expense is classified in our statements of operations in the same manner in which the awardrecipients’ payroll costs are classified or in which the award recipients’ service payments are classified. The fair value of each stock warrant grant is estimated on the date of grant using a Black-Scholes model. The following summarizesthe inputs used:

Expected volatility—We are a private company and, as such, lack company-specifichistorical and implied volatility information. Therefore, we estimate our expected stock volatility based on the historical volatility of a publicly traded set of peer companies and we expect to continue to do so until we have adequate historicaldata regarding the volatility of our own publicly traded stock price.

Expected term—Our termexpectation represents the period that warrants are expected to be outstanding and is determined using the simplified method, based on the mid-point between the vesting date and the end of the contractualterm. We do not have sufficient historical data to use any other method to estimate expected term.

Risk-freeinterest rate—The risk-free interest rate is based on the implied yield on a U.S. Treasury security at a constant maturity with a remaining term equal to the expected term of the warrant granted.

Dividends—Expected dividend yield is zero because we do not expect to pay cash dividends on class Aordinary shares in the foreseeable future.

We recorded equity-based compensation expense of $64,000 and $131,000 relatedto the issuance of stock warrants during the years ended December 31, 2020 and 2019, respectively. As of December 31, 2020, there was $18,000 of unrecognized compensation cost related to unvested stock-based compensation arrangements thatis expected to be recognized over a weighted average period of one year.

Equity-based compensation expense recorded asresearch and development and general and administrative expenses is as follows:

11. Income Taxes

We are subject to taxes for earnings generated in Denmark and our tax expense is primarily affected by unrecognized taxbenefits in Denmark. There are no income tax provisions or benefits for the years ended December 31, 2020 and 2019. Our effective tax rate differs from the statutory rate each year mainly due to a full valuation allowance.

Our loss before provision (benefit) for income taxes for the years ended December 31, 2020, and 2019 consisted of thefollowing:

        2020            2019

Reconciliation of Effective Tax Rate

Our effective tax rate for the years ended December 31, 2020 and 2019 is different from the statutory rate in Denmarkprimarily due to the valuation allowance against deferred tax assets as a result of insufficient sources of income. The reconciliation of the statutory income tax rate to our effective income tax rate is as follows:

 

   Year Ended December 31, 
        2020            2019

Deferred Taxes

Deferred tax assets and liabilities represent future tax consequences of temporary differences between the financial statementcarrying amounts and the tax basis of assets and liabilities and for loss carryforwards using enacted tax rates expected to be in effect in the years in which the differences reverse. A valuation allowance is recorded when it is more likely than notthat some or all of the deferred tax assets will not be realized. The principal components of the Company’s deferred tax assets consisted of the following (in thousands):

 

   December 31, 
   2020  2019 

Deferred tax assets/liabilities

We determine whether it is more likely than not that a tax position will be sustained uponexamination. If it is not more likely than not that a position will be sustained, none of the benefit attributable to the position is recognized. The tax benefit to be recognized for any tax position that meets the more likely than not recognitionthreshold is calculated as the largest amount that is more than 50%.

Table of Contents

When realization of a deferred tax asset is more likely than not to occur,the benefit related to the deductible temporary differences attributable to operations is recognized as a reduction of income tax expense. Valuation allowances are provided against deferred tax assets when, based on all available evidence, it isconsidered more likely than not that some portion or all of the recorded deferred tax assets will not be realized in future periods. We cannot be certain that future income in Denmark will be sufficient to realize the Company’s deferred taxassets. Accordingly, a full valuation allowance has been provided against our net deferred tax assets. The valuation allowance increased by $2.3 million in 2020. The increase in 2020 is primarily the result of an increase in net operating losscarryforwards, or NOLs.

Available Carryforward Tax Losses

At December 31, 2020, we had NOL carryforwards of approximately $23.8 million that can be carried forwardindefinitely according to Danish Tax Authority regulations.

Uncertain Tax Positions

We determine our uncertain tax positions based on whether and how much of a tax benefit taken by us in our tax filings is morelikely than not to be sustained upon examination by the relevant income tax authorities. We have reviewed the tax positions taken, or to be taken, in our tax returns for all tax years currently open to examination by the Danish Tax Authority. As ofDecember 31, 2020 and 2019, we have not recorded an uncertain tax position liability

Tax filings in Denmark remainsubject to examination by the Danish Tax Authority. As of December 31, 2020, tax years 2017 and forward were generally open to examination by the Danish Tax Authority.

Other Tax Matters

The Company recognizes accrued interest related to unrecognized tax benefits and penalties as income tax expense. The Companydoes not have any material unrecognized tax benefits which would affect the effective tax rate if recognized. The Company does not have any unrecognized tax benefits which would reverse within the next twelve months.

The Company is eligible for the Danish enhanced research and development tax allowance, providing for an increase in thedeductible value of the amount of certain R&D expenditures. For 2019, the deduction is set at 101.5%. Furthermore, the deduction for R&D expenditures is set at 130% for 2020 through 2022, 108% for 2023 through 2025, and 110% for 2026.

In addition, in 2013 the Folketinget, or Danish Parliament, introduced a tax credit policy that allows companies with lossesresulting from research and development costs to receive payment of the tax base of losses of up to 25 million DKK. We have historically met the requirements to receive payment. The tax credit is reported as a reduction to research anddevelopment expense in the statements of operations. For the years ended December 31, 2020 and 2019, we applied for refundable tax credit of 25 million DKK for each year and a receivable was recorded for $0.9 million and$0.8 million respectively.

1. Description of Business, Organization and Liquidity

Business

IO Biotech ApS is a clinical-stage biotechnology company dedicated to the identification and development of disruptive immunetherapies for the treatment of cancer. As used in these financial statements, unless the context otherwise requires, references to the “Company”, “we,” “us,” and “our” refer to IO Biotech ApS. We wereincorporated in Denmark in December 2014. We are developing novel, immune-modulating cancer therapies based on our T-win technology platform.

Risks and Uncertainties

We are subject to risks common to companies in the biotechnology industry including, but not limited to, new technologicalinnovations, protection of proprietary technology, dependence on key personnel, compliance with government regulations and the need to obtain additional financing. Product candidates currently under development will require significant additionalresearch and development efforts, including extensive pre-clinical and clinical testing and regulatory approval, prior to commercialization. These efforts require significant amounts of additional capital,adequate personnel infrastructure and extensive compliance reporting capabilities.

Our product candidates are indevelopment. There can be no assurance that our research and development will be successfully completed, that adequate protection for our intellectual property will be obtained, that any products developed will obtain necessary government regulatoryapproval or that any approved products will be commercially viable. Even if our product development efforts are successful, it is uncertain when, if ever, we will generate significant revenue from product sales. We operate in an environment of rapidchange in technology and substantial competition from pharmaceutical and biotechnology companies. In addition, we are dependent upon the services of our employees and consultants.

Liquidity Considerations

Since inception, we have devoted substantially all our efforts to business planning, conducting research and development,recruiting management and technical staff, and raising capital. We have financed our operations primarily through the issuance of convertible preference shares and convertible notes.

Our continued discovery and development of its product candidates will require significant additional research and developmentefforts, including extensive preclinical and clinical testing and regulatory approval prior t commercialization These efforts require significant amounts of additional capital, adequate personnel and infrastructure and extensive compliance-reportingcapabilities. Even if product development efforts are successful, it is uncertain when, if ever, we will realize significant revenue from product sales.

As of June 30, 2021, we had an accumulated deficit of $83.9 million. We have incurred losses and negative cash flowsfrom operations since inception, including net losses of $45.5 million and $6.0 million for the six months ended June 30, 2021 and year ended December 31, 2020, respectively. We expect that our operating losses and negative cashflows will continue for the foreseeable future as we continue to develop our product candidates. We currently expect that our cash and cash equivalents of $54.8 million as of June 30, 2021 together with the proceeds on closings of theclass C preference shares, for gross proceeds of $             million in                  2021 will besufficient to fund our operating expenses and capital requirements for at least 12 months from the date the financial statements are issued. However, additional funding will be necessary to fund future discovery research, pre-clinical and clinical activities. We will seek additional funding through public financings, debt financings, collaboration agreements, strategic alliances and licensing arrangements. Although we have beensuccessful in raising capital in the past, there is no assurance that we will be successful in obtaining such additional financing on terms acceptable to it, if at all, and we may not be able to enter into collaborations

or other arrangements. If we are unable to obtain funding, we could be forced to delay, reduce or eliminate our research and development programs, product portfolio expansion or commercializationefforts, which could adversely affect our business prospects, even our ability to continue operations.

CoronavirusPandemic

In March 2020, the World Health Organization declared theCOVID-19 outbreak a pandemic. In order to mitigate the spread of COVID-19, governments have imposed unprecedented restrictions on business operations, travel andgatherings, resulting in a global economic downturn and other adverse economic and societal impacts. The COVID-19 pandemic has also overwhelmed or otherwise led to changes in the operations of many healthcarefacilities, including clinical trial sites. While we are considered an essential business under applicable regulations and continue to operate, the impacts of COVID-19 initially placed significant strain onour clinical trial sites, have raised concerns around monitoring patient safety, and resulted in changes to patient visit frequencies. We are continuing to work closely with our clinical partners and have taken steps as necessary to adjust ourprotocols and timelines due to the impact of the COVID-19 pandemic. The COVID-19 pandemic and its impacts continue to evolve. We cannot predict the scope and severity ofany further disruptions as a result of COVID-19 or their impacts on us, but business disruptions for us or any of the third parties with whom we engage, including the collaborators, contract organizations,third-party manufacturers, suppliers, clinical trial sites, regulators and other third parties with whom we conduct business could materially and negatively impact our ability to conduct our business in the manner and on the timelines presentlyplanned. The extent to which the COVID-19 pandemic may continue to impact our business and financial performance will depend on future developments, which are highly uncertain and cannot be predicted withconfidence, including the scope and duration of the pandemic, the extent and effectiveness of government restrictions and other actions, including relief measures, implemented to address the impact of the pandemic, and resulting economic impacts.

The actual and perceived impact of the COVID-19 pandemic is changing daily, andits ultimate effect on our business cannot be predicted. As a result, there can be no assurance that we will not experience additional negative impacts associated with COVID-19, which could be significant. TheCOVID-19 pandemic may negatively impact our business, financial condition and results of operations causing interruptions or delays in the Company’s programs and services.

Recently Issued Accounting Standards

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), as amended,with guidance regarding the accounting for and disclosure of leases. ASU 2016-02 requires lessees to recognize the liabilities related all leases, including operating leases, with a term greater than 12 monthson the balance sheet. This update also requires lessees and lessors to disclose key information about their leasing transactions. This standard is effective for annual reporting periods beginning after December 15, 2021, and interim periodswithin annual periods beginning after December 15, 2022. Early adoption is permitted. We are currently assessing the potential impact of adopting ASU 2016-02 on our financial statements and financialstatement disclosures.

In June 2016, the FASB issued Accounting Standards UpdateNo. 2016-13, Financial Instruments-Credit Losses: Measurement of Credit Losses on Financial Instruments. ASU 2016-13 requires measurement and recognitionof expected credit losses for financial assets. In April 2019, the FASB issued clarification to ASU 2016-13 within ASU 2019-04, CodificationImprovements to Topic 326, Financial Instruments-Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments, or ASU 2016-13. The guidance is effective for fiscalyears beginning after December 15, 2022. We are currently assessing the potential impact of adopting ASU 2016-13 on our financial statements and financial statement disclosures.

In December 2019, the FASB issued ASU 2019-12, Simplifying the Accounting forIncome Taxes, or ASU 2019-12. ASU 2019-12 eliminates certain exceptions related to the approach for intra-period tax allocation, the methodology for calculatingincome taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. It also clarifies and simplifies other aspects of the accounting for income taxes. This guidance is effective for fiscal years beginningafter December 15, 2021, and interim periods within fiscal years beginning after December 15, 2022. Early adoption is permitted. We are currently assessing the impact adoption of ASU 2019-12 willhave on our financial statements and disclosures.

In August 2020, the FASB issued ASUNo. 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging Contracts in Entity s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity. ASU 2020-06 will simplify the accounting for convertible instruments byreducing the number of accounting models for convertible debt instruments and convertible preferred stock. Limiting the accounting models results in fewer embedded conversion features being separately recognized from the host contractas compared with current GAAP. Convertible instruments that continue to be subject to separation models are (i) those with embedded conversion features that are not clearly and closely related to the host contract, that meet thedefinition of a derivative, and that do not qualify for a scope exception from derivative accounting and (ii) convertible debt instruments issued with substantial premiums for which the premiums are recorded as paid-in capital. ASU 2020-06 also amends the guidance for the derivatives scope exception for contracts in an entity’s own equity to reduceform-over-substance-based accounting conclusions. ASU 2020-06 will be effective for us beginning after December 15, 2023. Early adoption is permitted, but no earlier than fiscal yearsbeginning after December 15, 2020, including interim periods within those fiscal years. We are currently assessing the impact adoption of ASU 2020-06 will have on our financial statementsand disclosures.

Valuation techniques used to measure fair value maximize the use of relevant observable inputsand minimize the use of unobservable inputs. Our convertible notes were classified within Level 3 of the fair value hierarchy because the fair value measurement was based, in part, on significant inputs not observed in the market.

In July 2019, we issued convertible notes to existing related party investors for proceeds of $9.0 million. Uponissuance, we elected the fair value option to account for the convertible notes, with any subsequent changes in fair value being recognized through the statements of operations as other income (expense) until the convertible notes are settled.We have not recorded interest expense separate from those fair value adjustments.

The convertible notes accrued interestat 8% per year beginning in August 2019 payable in cash or, at the investor’s discretion, into our class B or class C preference shares. In April 2020, the convertible notes plus accrued interest of $0.5 million, were converted accordingto the terms of the convertible notes into 142,437 shares of class B preference shares (Note 8). On conversion in April 2020, we determined the fair value of the convertible notes with reference to the class B preference shares (Note 8)into which the convertible notes were converted into (142,437).

Our class C Preference Shares Tranche Obligation ismeasured at fair value using a Black-Scholes option pricing valuation methodology. The fair value of class C Preference Shares Tranche Obligation includes inputs not observable in the market and thus represents a Level 3 measurement. The optionpricing valuation methodology utilized requires inputs based on certain subjective assumptions, including (i) expected stock price volatility, (ii) calculation of an expected term, (iii) a risk-free interest rate, and(iv) expected dividends. The assumptions utilized to value the class C Preference Shares Tranche Obligation as of June 30, 2021 were (i) expected stock price volatility of 73.7%; (ii) remaining term of 0.3 years; (iii) a risk-freeinterest rate of 0.05%; and (iv) an expectation of no dividends.

There were no transfers among Level 1,Level 2 or Level 3 categories in the years ended December 31, 2020 or 2019.

4. License and Collaboration Agreements

In February 2018, we entered into a clinical collaboration with MSD International GmbH, or MSD, to evaluate IO102 incombination with KEYTRUDA® (pembrolizumab) in first-line treatment of patients with metastatic non-small cell lung cancer. Under the terms of thecollaboration with MSD, we will conduct an

Table of Contents

Legal Proceedings

From time to time, we may be party to litigation arising in the ordinary course of its business. We were not subject to anymaterial legal proceedings during the six months ended June 30, 2021 and year ended December 31, 2020, and, to our knowledge, no material legal proceedings are currently pending or threatened.

Research Agreements

The Company and the Herlev University Hospital in Denmark (“Herlev”) have a number of existing agreements forscientific and other support of the Company’s ongoing development activities. In January 2021, the Company entered into an additional agreement with Herlev regarding the payment of specific services whereupon in addition to any considerationpayable by the Company to Herlev pursuant to the existing agreements the Company shall pay a fee to Herlev of DKK 5.0 million (approximately $0.8 million) in the event of an initial public offering or other liquidity event whereby all orsubstantially all of the value of the Company is realized in consideration for cash.

Indemnification Agreements

We enter into certain types of contracts that contingently requires us to indemnify various parties against claimsfrom third parties. These contracts primarily relate to procurement, service, consultancy or license agreements under which we may be required to indemnify vendors, service providers or licensees for certain claims, including claims that may bebrought against them arising from our acts or omissions with respect to our products, technology, intellectual property or services.

From time to time, we may receive indemnification claims under these contracts in the normal course of business. In the eventthat one or more of these matters were to result in a claim against us, an adverse outcome, including a judgment or settlement, may cause a material adverse effect on our future business, operating results or financial condition. It is not possibleto estimate the maximum amount potentially payable under these contracts since we have no history of prior indemnification claims and the unique facts and circumstances involved in each particular claim will be determinative.

8. Convertible Preference Shares

As of June 30, 2021 and December 31, 2020, we had 584,583 class B preference shares authorized, issued andoutstanding. As of June 30, 2021, we had 1,263,804 class C preference shares authorized and 541,345 class C preference shares issued and outstanding.

In April 2020, we issued 142,437 class B preference shares at a subscription price of $64.48 per share to existingrelated-party investors upon the conversion of convertible notes (Note 3). We recorded the 142,437 class B preference shares at fair value of $10.3 million ($72.15 per share) determined using an option pricing model, or OPM, assuming aCompany equity value of $40.6 million, a term of 1.6 years, volatility of 86.0% and a risk-free rate of 0.18%. We incurred issuance costs of $4,000 in connection with the issuances of the class B preference shares on conversion of theconvertible notes.

In July 2020, we issued 75,845 class B preference shares to existing related-party investors at asubscription price of $67.46 per share for gross cash proceeds of $5.1 million. We recorded the 75,845 class B preference shares at fair value of $5.6 million ($73.60 per share), resulting in a deemed dividend of $0.5 million recordedagainst additional paid-in capital on our balance sheet. Fair value of the class B preference shares issued on this date was determined using an OPM methodology assuming a Company equity value of$47.6 million, a term of 1.36 years, volatility of 92.4% and a risk-free rate of 0.16%. We incurred issuance costs of $10,000 in connection with the issuances of the class B preference shares.

 

F-31


Table of Contents

In January 2021, we completed an investment agreement, Class CInvestment Agreement, for the sale and issuance of up to 1,263,804 class C preference shares to new investors and existing related-party investors at a subscription price of $121.55 per share. Then, pursuant to the Class C Investment Agreement,we issued 505,520 class C preference shares for gross cash proceeds of $61.5. The Class C Investment Agreement further provides for a milestone closing in the event of certain development milestones before April 2022, whereby purchasers ofclass C preference shares are obligated to a further subscription amount of $92.2 million, or the Preference Shares Tranche Obligation, which may result in a further issuance of 689,349 class C preference shares at a subscription price of$131.00 per share, using the exchange rate as of June 30, 2021. We incurred issuance costs of $340,000 in connection with the issuances of the class C preference shares.

We concluded that the Preference Shares Tranche Obligation met the definition of a freestanding financial instrument, as it islegally detachable and separately exercisable from the class C preference shares. Therefore, we allocated the proceeds received from the issuance of shares under the Class C Investment Agreement between the Preference Shares Tranche Obligationand the class C preference shares. The fair value of the Preference Shares Tranche Obligation of $2.4 million on issuance was allocated from the $61.5 million proceeds of the class C preference shares financing and is classified as acurrent liability on the balance sheet as of June 30, 2021 as the class C preference shares would become redeemable upon a Deemed Liquidation Event, the occurrence of which is not within our control.

In March 2021, prior to a milestone closing, an investor elected to purchase and we issued 35,825 class C preference sharesfor gross cash proceeds of $4.2 million pursuant to the Class C Investment Agreement. As a result of entering into a collaboration agreement with Merck in September 2021, the number of class C preference shares issued in March 2021 wasadjusted downward to 32,568 class C preference shares.

The holders of Preference Shares are entitled to one vote per share on all matters to be voted upon at all shareholdermeetings and written actions in lieu of meetings. The holders of Preference Shares are entitled to elect six of the eight directors on our board.

Anti-Dilution Protection

In the event we issue any additional shares for a consideration per share that is less than the applicable subscription pricepaid for the Preference Shares, the subscription price of the applicable Preference Shares (as adjusted for share splits, payment of dividends, recapitalization, consolidations of shares and similar events) for existing shareholders who participatein the purchase of such additional shares shall be adjusted on a weighted average basis. The adjustment shall be made through the issuance of new Preference Shares of the relevant class to the Preference Shareholders at quota value.

Redemption

Preference Shares are not subject to mandatory redemption. Upon certain change in control events that are outside of ourcontrol, including liquidation, sale or transfer of control of the Company, the Preference Shares are contingently redeemable.

9. Ordinary Shares

The holders of class A ordinary shares are entitled to an allocation and distribution of proceedsin a Liquidity Event subject to the Liquidation Preference. When the Liquidity Preference has been paid in full, any remaining proceeds shall be allocated pro rata to all shares in the Company.

The holders of class A ordinary shares are entitled to one vote per share on all matters to be voted upon at all shareholdermeetings and written actions in lieu of meetings. Together, as a single class with holders of Preference Shares, holders of class A ordinary shares may appoint two independent directors of our board.

10. Equity-Based Compensation

Employee Equity Plan

We may award up to 335,009 warrants. Each vested warrant will entitle the warrant holder to a single class A ordinary share.Holders of stock warrants are entitled to exercise the vested portion of the stock warrant. Stock warrants generally vest over a three-year period and expire five years from the vest date.

At June 30, 2021, we had 309,630 warrants available for future grant under our employee equity plan. There were nogrants, exercises, or forfeitures of any stock warrants during the six months ended June 30, 2021 and 2020.

Equity-Based Compensation

All share-based awards granted are measured based on the fair value on the date of the grant and compensation expense isrecognized with respect to those awards over the requisite service period, which is generally the vesting period of the respective award. Forfeitures related to equity-based compensation awards are recognized as they occur, and we reverse anypreviously recognized compensation cost associated with forfeited awards in the period the forfeiture occurs.

We recordedequity-based compensation expense of $9,000 and $32,000 related to the issuance of stock warrants during the six months ended June 30, 2021 and 2020, respectively. As of June 30, 2021, there was $9,000 of unrecognized compensation costrelated to unvested stock-based compensation arrangements that is expected to be recognized over a weighted average period of 0.5 year.

Equity-based compensation expense recorded as research and development and general and administrative expenses is as follows:

11. Income Taxes

We are subject to taxes for earnings generated in Denmark and our tax expense is primarily affected by unrecognized taxbenefits in Denmark. We did not record a provision or benefit for income taxes during the six months ended June 30, 2021 or 2020. We continue to maintain a full valuation allowance against all of our deferred tax assets.

We have evaluated the positive and negative evidence involving our ability to realize our deferred tax assets. We haveconsidered our history of cumulative net losses incurred since inception and our lack of any commercial products. We have concluded that it is more likely than not that we will not realize the benefits of our deferred tax assets. We reevaluate thepositive and negative evidence at each reporting period.

Report of Independent Registered Public Accounting Firm

To the Stockholder and the Board of Directors of IO Biotech, Inc.

Opinion on the Financial Statements

Wehave audited the accompanying balance sheet of IO Biotech, Inc. (the Company) as of October 14, 2021 and the related notes (collectively referred to as the “balance sheet”). In our opinion, the balance sheet presents fairly, in allmaterial respects, the financial position of the Company at October 14, 2021, in conformity with U.S. generally accepted accounting principles.

Basis for Opinion

The balance sheet isthe responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s balance sheet based on our audit. We are a public accounting firm registered with the Public Company Accounting Oversight Board(United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtainreasonable assurance about whether the balance sheet is free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Aspart of our audit, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting.Accordingly, we express no such opinion.

Our audit included performing procedures to assess the risks of material misstatement of thebalance sheet, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the balance sheet. Our audit also includedevaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the balance sheet. We believe that our audit provides a reasonable basis for our opinion.

Item 14. Indemnification of Directors and Officers

IO Biotech, Inc. is incorporated under the laws of the State of Delaware. Reference is made to Section 102(b)(7) of theDGCL, which enables a corporation in its original certificate of incorporation or an amendment thereto to eliminate or limit the personal liability of a director for violations of the director’s fiduciary duty, except (1) for any breach ofthe director’s duty of loyalty to the corporation or its stockholders, (2) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (3) pursuant to Section 174 of the DGCL,which provides for liability of directors for unlawful payments of dividends or unlawful stock purchase or redemptions or (4) for any transaction from which the director derived an improper personal benefit.

Section 145(a) of the DGCL provides, in general, that a corporation may indemnify any person who was or is a party or isthreatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation), because he or she is or was adirector, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses(including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by the person in connection with such action, suit or proceeding, if he or she acted in good faith and in a manner he or shereasonably believed to be in or not opposed to the best interests of the corporation and, with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful.

Section 145(b) of the DGCL provides, in general, that a corporation may indemnify any person who was or is a party or isthreatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in its favor because the person is or was a director, officer, employee or agent of the corporation, oris or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys’ fees) actually and reasonablyincurred by the person in connection with the defense or settlement of such action or suit if he or she acted in good faith and in a manner he or she reasonably believed to

Table of Contents

be in or not opposed to the best interests of the corporation, except that no indemnification shall be made with respect to any claim, issue or matter as to which he or she shall have beenadjudged to be liable to the corporation unless and only to the extent that the adjudicating court determines that, despite the adjudication of liability but in view of all of the circumstances of the case, he or she is fairly and reasonablyentitled to indemnity for such expenses which the adjudicating court shall deem proper.

Section 145(g) of the DGCLprovides, in general, that a corporation may purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director,officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against any liability asserted against such person and incurred by such person in any such capacity, or arising out of his or her status assuch, whether or not the corporation would have the power to indemnify the person against such liability under Section 145 of the DGCL.

We expect that the amended and restated certificate of incorporation adopted by us prior to the completion of this offeringwill provide that no director of our company shall be personally liable to us or our stockholders for monetary damages for any breach of fiduciary duty as a director, except for liability (1) for any breach of the director’s duty ofloyalty to us or our stockholders, (2) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (3) in respect of unlawful dividend payments or stock redemptions or repurchases or otherdistributions pursuant to Section 174 of the DGCL, or (4) for any transaction from which the director derived an improper personal benefit. In addition, our charter will provide that if the DGCL is amended to authorize the furtherelimination or limitation of the liability of directors, then the liability of a director of our company shall be eliminated or limited to the fullest extent permitted by the DGCL, as so amended.

We also expect our charter will further provide that any amendment, repeal or modification of such article unless otherwiserequired by law will not adversely affect any right or protection existing at the time of such repeal or modification with respect to any acts or omissions occurring before such repeal or amendment of a director serving at the time of such repeal ormodification.

We expect that our amended and restated certificate of incorporation adopted by us prior to the completionof this offering, will provide that we shall indemnify each of our directors and executive officers, and shall have power to indemnify our other officers, employees and agents, to the fullest extent permitted by the DGCL as the same may be amended(except that in the case of an amendment, only to the extent that the amendment permits us to provide broader indemnification rights than the DGCL permitted us to provide prior to such the amendment) against any and all expenses, judgments,penalties, fines and amounts reasonably paid in settlement that are incurred by the director, officer or such employee or on the director’s, officer’s or employee’s behalf in connection with any threatened, pending or completedproceeding or any claim, issue or matter therein, to which he or she is or is threatened to be made a party because he or she is or was serving as a director, officer or employee of our company, or at our request as a director, partner, trustee,officer, employee or agent of another corporation, partnership, joint venture, trust, employee benefit plan or other enterprise, if he or she acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the bestinterests of our company and, with respect to any criminal proceeding, had no reasonable cause to believe his or her conduct was unlawful. We expect the amended and restated certificate of incorporation will further provide for the advancement ofexpenses to each of our directors and, in the discretion of the board of directors, to certain officers and employees, in advance of the final disposition of such action, suit or proceeding only upon receipt of an undertaking by such person to repayall amounts advanced if it shall ultimately be determined by final judicial decision from which there is no further right to appeal that such person is not entitled to be indemnified for such expenses.

In addition, we expect the amended and restated certificate of incorporation will provide that the right of each of ourdirectors and officers to indemnification and advancement of expenses shall not be exclusive of any

other right now possessed or hereafter acquired under any statute, provision of the charter or bylaws, agreement, vote of stockholders or otherwise. Furthermore, our amended and restatedcertificate of incorporation will authorize us to provide insurance for our directors, officers, employees and agents against any liability, whether or not we would have the power to indemnify such person against such liability under the DGCL or thebylaws.

We have entered into indemnification agreements with each of our directors and our executive officers. Theseagreements will provide that we will indemnify each of our directors and such officers to the fullest extent permitted by law and our amended and restated certificate of incorporation.

We also maintain a general liability insurance policy which covers certain liabilities of directors and officers of ourcompany arising out of claims based on acts or omissions in their capacities as directors or officers.
