Risk Factors Summary

Below is a summary of material factors that make an investment in our securities speculative or risky. Importantly, this summary does not address all of the risks and uncertainties that we face. You should carefully consider the full risk factor disclosure outlined in this Annual Report, in addition to the other information herein, including the section of this report titled “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and our financial statements and related notes.

•

We are a clinical-stage biopharmaceutical company and have incurred significant losses since our

inception. We may incur losses for the foreseeable future and may not be able to generate sufficient revenue to maintain profitability.

•

Our limited operating history makes future forecasting difficult.

•

The successful development of pharmaceutical products is highly uncertain.

•

All of our product candidates are in preclinical or clinical development. Clinical drug development is expensive, time consuming and uncertain, and we may ultimately not be able to obtain regulatory approvals for the commercialization of some or all of our product candidates.

•

Any delay in obtaining or failure to obtain required approvals could materially adversely affect our ability to generate revenue from the particular product candidate, which likely would result in significant harm to our financial position and adversely impact our stock price.

•

Regulatory approval for the genetic modification of animals, including those from which antibodies are isolated for injection into human patients, requires the approval of a New Animal Drug Application, which can be a lengthy and expensive process with uncertain outcomes, delays to which could substantially harm our business.

•

If we encounter difficulties enrolling patients in clinical trials, clinical trials of our product candidates may be delayed or otherwise adversely affected.

•

Our preclinical studies and clinical trials may fail to demonstrate substantial evidence of the safety and efficacy of our 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 their commercialization, increase costs or necessitate the abandonment or limitation of the development of some of our product candidates.

•

Our business is highly dependent on the success of our product candidates. If we are unable to successfully complete clinical development, obtain regulatory approval for or commercialize one or more of our product candidates, or if we experience delays in doing so, our business will be materially harmed.

•

We conduct certain research and development operations through our Australian wholly-owned subsidiary. If we lose our ability to operate in Australia, or if our subsidiary is unable to receive the research and development tax credit allowed by Australian regulations, our business and results of operations could suffer.

•

The regulatory approval processes of the FDA are lengthy, time-consuming and inherently unpredictable, and if we are ultimately unable to obtain regulatory approval for our product candidates, our business will be substantially harmed.

•

We may never obtain FDA approval for any product candidates in the United States, and even if we do, we may never obtain approval for or commercialize any product candidates in any other jurisdiction, which would limit our ability to realize their full market potential.

•

The FDA or comparable foreign regulatory authorities may disagree with our regulatory plan for our product candidates.

•

If our clinical trials fail to replicate positive results from earlier preclinical studies or clinical trials conducted by us or third parties, we may be unable to successfully develop, obtain regulatory approval for or commercialize our product candidates.

•

We may incur unexpected costs or experience delays in completing, or ultimately be unable to complete, the development and commercialization of our product candidates.

•

Even if we complete the necessary preclinical studies and clinical trials, the marketing approval process for product candidates is expensive, time-consuming and uncertain, and may prevent us from obtaining approvals for the commercialization of our product candidates.

•

If we experience delays in obtaining approval or if we fail to obtain approval of any product candidates we may develop, the commercial prospects for those product candidates may be harmed, and our ability to generate revenues will be materially impaired.

•

If we do not achieve our projected development and commercialization goals in the timeframes we announce and expect, the development and commercialization of our product candidates may be delayed, and our business and results of operations may be harmed.

•

Changes in methods of product candidate manufacturing or formulation may result in additional costs or delays.

•

Our product candidates may cause undesirable side effects or have other properties that could delay or prevent their regulatory approval, limit the commercial profile of an approved label, or result in significant negative consequences following regulatory approval, if obtained.

•

The future commercial success of our product candidates will depend on the degree of market acceptance of our potential products among physicians, patients, healthcare payers, and the medical community.

•

Failure to successfully identify, develop and commercialize additional products or product candidates could impair our ability to grow.

•

If we are unable to develop our sales, marketing and distribution capability on our own or through collaborations with marketing partners, we will not be successful in commercializing our product candidates.

•

Product liability lawsuits against us or any of our future collaborators could divert our resources and attention, cause us to incur substantial liabilities and limit commercialization of our product candidates.

•

Our current and future relationships with customers and third party payors in the United States and elsewhere may be subject, directly or indirectly, to applicable anti-kickback, fraud and abuse, false claims, transparency, health information privacy and security and other healthcare laws and regulations, which could expose us to criminal sanctions, civil penalties, contractual damages, reputational harm, administrative burdens and diminished profits and future earnings.

•

Regulatory approval for any approved product is limited by the FDA to those specific indications and conditions for which clinical safety and efficacy have been demonstrated.

•

Current and future legislation may increase the difficulty and cost for us to obtain marketing approval of and commercialize any product candidates we or our collaborators develop and may adversely affect the prices for such product candidates.

•

Even if we obtain regulatory approval for our product candidates, our products will remain subject to regulatory scrutiny.

•

A prolonged U.S. federal government shutdown could materially and adversely affect our business, operations, and legal proceedings.

•

Unfavorable global economic conditions and government regulations could adversely affect our business, financial condition or results of operations.

•

We must attract and retain highly skilled personnel and strategic partners, and we may be unable to effectively manage our growth with our limited resources.

•

We anticipate adding new employees and we will have to integrate such new employees into our operations.

•

Our employees and independent contractors may engage in misconduct or other improper activities, including noncompliance with regulatory standards and requirements, which could negatively impact our business, prospects, financial condition and operating results.

•

We are limited in our ability to manufacture pharmaceutical products.

•

We depend upon senior management and senior scientific staff, and their loss or unavailability could put us at a competitive disadvantage.

•

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

•

We intend to rely on third parties to produce commercial supplies of our product candidates.

•

If we fail to successfully operate our animal production facility, it may adversely affect our clinical trials and the commercial viability of our product candidates.

•

Tariffs could adversely affect our business and financial results.

•

Our success depends on our ability to maintain the proprietary nature of our technology.

•

Third parties may claim we infringe their intellectual property rights.

•

We may become involved in litigation to protect or enforce our patents or the patents of our collaborators or licensors, which could be expensive and time-consuming.

•

If patent laws or the interpretation of patent laws change, our competitors may be able to develop and commercialize our discoveries.

•

We have third party collaborators that might claim rights in or to our technology and/or assets.

•

Changes in patent law in the United States and in ex-U.S. jurisdictions could diminish the value of patents in general, thereby impairing our ability to protect our products.

We rely heavily on trade secrets and proprietary know-how to protect our technology, and if our employees, consultants, or collaborators disclose such information or if our Tc Bovine, HAC or proprietary cell lines are misappropriated, competitors could replicate our platform.

•

The U.S. government may have march-in rights with respect to certain of our intellectual property, which could limit our ability to exclusively commercialize products developed with government funding.

•

If we do not obtain patent term extension and data exclusivity for any product candidates we may develop, our business may be materially harmed.

•

The regulatory pathway for approval of biosimilars or interchangeable biologics to our products is uncertain, which may create competitive risks

•

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

•

We are an “emerging growth company,” and our election to comply with the reduced disclosure requirements as a public company may make our common stock less attractive to investors.

•

We incur increased costs and demands upon management as a result of complying with the laws and regulations affecting public companies, which could adversely affect our business, financial condition, and results of operations.

•

If we fail to maintain an effective system of disclosure controls and internal control over financial reporting, our ability to produce timely and accurate financial statements or comply with applicable regulations could be impaired.

•

Our warrants are accounted for as liabilities and changes in value of the warrants could have a material effect on our financial results.

•

Our business, financial condition, and results of operations may fluctuate on a quarterly and annual basis, which may result in a decline in our stock price if such fluctuations result in a failure to meet the expectations of securities analysts or investors.

•

Changes in accounting principles may cause previously unanticipated fluctuations in our financial results, and the implementation of such changes may impact our ability to meet our financial reporting obligations.

•

If our estimates or judgments relating to our critical accounting policies prove to be incorrect, our business, financial condition, and results of operations could be adversely affected.

•

Anti-takeover provisions contained in our certificate of incorporation as well as provisions of Delaware law, could impair a takeover attempt.

•

The market price of our securities may be volatile, which could cause the value of any investment in our securities to decline.

•

An investment in our common stock is extremely speculative and there can be no assurance of any return on any such investment.

•

There can be no assurance that we will be able to comply with the continued listing standards of Nasdaq.

•

Because we have no current plans to pay cash dividends on our common stock for the foreseeable future, investors may not receive any return on their investment unless they sell their common stock for a price greater than the price paid.

•

Sales of a substantial number of shares of our common stock in the public market could cause our stock price to fall.

•

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

•

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

•

We have a significant number of (i) warrants which are currently exercisable for shares of our common stock or shares of preferred stock convertible into shares of our common stock, and (ii) shares of preferred stock convertible into shares of common stock, and the exercise or conversion thereof would increase the number of shares eligible for future resale in the public market and result in dilution to our stockholders.

•

If securities or industry analysts do not publish research or reports about our business or publish negative reports, the market price of our common stock could decline.

•

Reports published by analysts, including projections in those reports that differ from our actual results, could adversely affect the price and trading volume of our common stock.

•

We may be subject to securities litigation, which is expensive and could divert management attention.

•

Changes in legislation in U.S. and foreign taxation of international business activities or the adoption of other tax reform policies, as well as the application of such laws, could adversely impact our financial position and operating results.

•

Our ability to use our net operating losses to offset future taxable income may be subject to certain limitations.

Risks Related to Our Business and Operations

We are a clinical-stage biopharmaceutical company and have incurred significant losses since our inception. We expect to continue to incur net losses for the foreseeable future, and we may never achieve or maintain profitability in the future.

We are a clinical-stage biopharmaceutical company. We expect to experience variability in revenue and expenses which makes it difficult to evaluate our business and prospects. As such, we have incurred and anticipate that we will continue to incur significant operating losses in the foreseeable future. Our historical losses resulted principally from costs incurred in research and development, preclinical testing, clinical development of product candidates as well as costs incurred for research programs and from general and administrative costs associated with these operations. In the future, we intend to continue to conduct research and development, preclinical testing, clinical trials and regulatory compliance activities that, together with anticipated general and administrative expenses, will result in incurring further significant losses for the next several years. We expect that our operating expenses will continue to increase significantly, including as we:

•

continue the research and development of our clinical- and preclinical-stage product candidates and discovery stage programs, including the clinical trials of SAB-142;

•

advance our preclinical-stage product candidates into clinical development;

•

invest in our technology and platform;

•

seek to identify, acquire and develop additional product candidates, including through business development efforts to invest in or in-license other technologies or product candidates;

•

seek regulatory approvals for any product candidates that successfully complete clinical trials;

•

market and sell our solutions to existing and new partners;

•

hire additional clinical, quality control, medical, scientific and other technical personnel to support our operations;

•

maintain, expand, enforce, protect, and defend our intellectual property portfolio;

•

create additional infrastructure to support operations;

•

add operational, financial, and management information systems and personnel to support operations as a public company;

•

seek regulatory approvals for any product candidates that successfully complete clinical trials;

•

undertake any pre-commercialization activities to establish sales, marketing and distribution capabilities for any product candidates for which we may receive regulatory approval in regions where we choose to commercialize our products on our own or jointly with third parties; and

•

experience any delays or encounter issues with any of the above.

Biopharmaceutical product development entails substantial upfront capital expenditures and significant risk that any potential product candidate will fail to demonstrate adequate efficacy or an acceptable safety profile, gain regulatory approval, secure market access and reimbursement and become commercially viable, and therefore any investment in us is highly speculative. Accordingly, before making an investment in us, you should consider our prospects, factoring in the costs, uncertainties, delays and difficulties frequently encountered by companies in clinical development, especially clinical-stage biopharmaceutical companies such as ours. Any predictions you make about our future success or viability may not be as accurate as they would otherwise be if we had a longer operating history or a history of successfully developing and commercializing pharmaceutical products. We may encounter unforeseen expenses, difficulties, complications, delays and other known or unknown factors in achieving our business objectives.

Our expenses could increase beyond expectations for a variety of reasons, including due to our growth strategy and the increase in the scope and complexity of our operations. In executing our strategy and plans to invest in enhancing and scaling our business, we will need to generate significant additional revenue to achieve and maintain future profitability. We may not be able to generate sufficient revenue to achieve profitability and our recent and historical growth should not be considered indicative of future performance.

Our limited operating history makes future forecasting difficult.

We commenced operations in April 2014 and became a public company in October 2021. As a result of our limited operating history, it is difficult to accurately forecast revenues or to predict operating expenses. Our current and future expense estimates are based, in large part, on our estimates of future revenue and on our research, development and commercialization plans. In particular, we plan to increase operating expenses significantly in order to expand our research, development and sales and marketing operations. To the extent that these expenses precede increased revenue, our business, results of operations and financial condition would be materially adversely affected. We may be unable to, or may elect not to, adjust spending quickly enough to offset any unexpected revenue shortfall. Therefore, any significant shortfall in revenue in relation to our expectations would also have a material adverse effect on our business, results of operations and financial condition.

The successful development of pharmaceutical products is highly uncertain.

We currently have no products approved for sale and are investing substantially all of our efforts and financial resources in the development of our immunotherapy platform and clinical development of our current lead programs. The success of our business, including our ability to finance our company and generate any revenue in the future, will primarily depend on the successful development, regulatory approval and commercialization of therapeutic biological product candidates. We will need to raise sufficient funds for, and successfully complete, our preclinical development programs and future clinical trials of product candidates for our lead programs.

There is no guarantee that any product candidate we develop will proceed into and through clinical development or achieve regulatory approval to allow such products to be commercialized. Successful development of therapeutic biological products is highly uncertain and is dependent on numerous factors, many of which are beyond our control. Product candidates that appear promising in the early phases of development may fail to reach the market for several reasons, including:

•

preclinical study results may show the product candidate to be less effective than desired or to have harmful side effects;

•

clinical trial results may show the product candidate to be less effective than expected (e.g., a clinical trial could fail to meet its primary or key secondary endpoint(s) or have an unacceptable safety or tolerability profile);

•

failure to receive the necessary regulatory approvals or a delay in receiving such approvals; and

•

post-marketing approval requirements.

In addition, the length of time necessary to complete clinical trials and submit an application for marketing approval for a final decision by a regulatory authority varies significantly among product candidates, and any delay in receipt of marketing approval for a product candidate could negatively impact market acceptance of any resulting product. Even if we are successful in obtaining marketing approval, commercial success of any approved products will also depend in large part on the availability of coverage and adequate reimbursement from third-party payors, including government payors such as the Medicare and Medicaid programs and managed care organizations in the United States or country specific governmental organizations in foreign countries, which may be affected by existing and future healthcare reform measures designed to reduce the cost of healthcare. Third-party payors could require us to conduct additional studies, including post-marketing studies related to the cost effectiveness of a product, to qualify for reimbursement, which could be costly and divert our resources. If government and other healthcare payors were not to provide coverage and adequate reimbursement for our products once approved, market acceptance and commercial success would be reduced.

In addition, if any of our product candidates receive marketing approval, we will be subject to significant regulatory obligations regarding the submission of safety and other post-marketing information and reports and registration, and will need to continue to comply (ensure that our third-party providers comply) with current Good Manufacturing Practices (cGMPs), and good clinical practices (GCPs), for any clinical trials that we conduct post-approval. In addition, there is always the risk that we, a regulatory authority or a third party might identify previously unknown problems with a product post-approval, such as adverse events of unanticipated severity or frequency. Compliance with these requirements is costly, and any failure to comply or other issues with our product candidates post-approval could adversely affect our business, financial condition and results of operations.

The research, testing, manufacturing, labeling, approval, selling, marketing and distribution of drug products are subject to extensive regulation by the FDA and other regulatory authorities, which regulations differ from country to country. Our product candidates are in various stages of development and are subject to the risks of failure typical of drug development. The development and approval process is expensive and can take many years to complete, and its outcome is inherently uncertain. We have not submitted an application for, or received, marketing approval for any of our product candidates. We have limited experience in conducting and managing the later-stage clinical trials necessary to obtain regulatory approvals, including approval by the FDA. To receive regulatory approval, we must, among other things, demonstrate with substantial evidence from clinical trials that the product candidate is safe and effective for each indication for which approval is sought, and failure can occur in any stage of development. Satisfaction of the approval requirements typically takes several years, and the time needed to satisfy them may vary substantially, based on the type, complexity and novelty of the pharmaceutical product. We cannot predict if or when we might receive regulatory approvals for any of our product candidates currently under development.

We cannot guarantee that any clinical trials will be conducted as planned or completed on schedule, if at all. Clinical development is susceptible to failure at any stage, including failure to demonstrate efficacy, occurrence of unacceptable adverse events, failure to comply with protocols or regulatory requirements, or determination by regulators that a product candidate is not approvable. Clinical trials may fail to detect beneficial effects or toxicity, or may indicate effects that differ from actual results. Serious adverse events or tolerability issues could hinder or prevent market acceptance of the product candidate.

The FDA and foreign regulatory authorities have substantial discretion in the drug approval process. The number and types of preclinical studies and clinical trials required for approval varies depending on the product candidate and target disease. Approval policies, regulations, and data requirements may change during development and vary among regulatory authorities. Regulatory agencies can delay, limit, or deny approval for many reasons, including:

•

the FDA or comparable foreign regulatory authorities may disagree with the design or implementation of our clinical trials;

•

the results of clinical trials may not meet the level of statistical or clinical significance required by the FDA or comparable foreign regulatory authorities for approval;

•

the clinical trial results may not confirm the positive results from earlier preclinical studies or clinical trials;

•

the FDA or comparable foreign regulatory authorities may disagree with our interpretation of data from preclinical studies or clinical trials;

•

the data collected from clinical trials of our product candidates may not be sufficient to the satisfaction of FDA or comparable foreign regulatory authorities to support the submission of a BLA or other comparable submission in foreign jurisdictions or to obtain regulatory approval in the United States or elsewhere;

•

regulatory agencies might not approve or might require changes to our manufacturing processes or facilities; and

•

regulatory agencies may change their approval policies, clinical development guidelines and recommendations, or adopt new regulations in a manner rendering our clinical data insufficient for approval.

This lengthy approval process, as well as the unpredictability of future clinical trial results, may result in our failing to obtain regulatory approval to market our product candidates, which would significantly harm our business, results of operations and prospects. The FDA or a comparable foreign regulatory authority may require more information, including additional preclinical or clinical data to support approval, which may delay or prevent approval and our commercialization plans, or which may lead us to decide to abandon the development program.

In addition, even if we were to obtain marketing approval, regulatory authorities may approve any of our product candidates for fewer or more limited indications than we request (including failing to approve the most commercially promising indications), may require a REMS that restricts prescribing or distribution of our therapeutic biological product candidates, may grant approval contingent on the performance of costly post-marketing clinical studies, or may approve a product candidate with a label that does not include the labeling claims necessary or desirable for the successful commercialization of that product candidate.

We are not permitted to market our product candidates in the United States until we receive approval of a NADA and BLA from the FDA or in other countries until we receive similar marketing authorization from applicable regulatory authorities outside the United States. We are also not permitted to promote our product candidates as safe and effective therapies until after receiving approval. Obtaining approval of a NADA or BLA can be a lengthy, expensive and uncertain process. If we fail to obtain FDA approval to market our product candidates, we will be unable to sell our product candidates in the United States, which will significantly impair our ability to generate any revenue. In addition, failure to comply with FDA and non-U.S. regulatory requirements may, either before or after product approval, if any, subject our company to administrative or judicially imposed sanctions, including:

•

restrictions on our ability to conduct clinical trials, including full or partial clinical holds on ongoing or planned trials;

•

restrictions on the products’ marketing, promotion, distribution or manufacturing processes;

•

warning letters or untitled letters alleging violations;

•

civil and criminal penalties;

•

injunctions;

•

suspension or withdrawal of regulatory approvals;

•

product seizures, detentions or import bans;

•

voluntary or mandatory product recalls and publicity requirements;

•

imposition of restrictions on operations, including costly new manufacturing requirements;

•

suspension of substantive review of pending applications, such as NADAs, BLAs, INADs, or INDs, pending data validation; and

•

refusal to approve pending NADAs or BLAs or supplements to approved NADAs or BLAs.

Even if we do receive regulatory approval to market a product candidate, any such approval may be subject to limitations on the indicated uses for which we may market the product. It is possible that none of our existing product candidates or any product candidates we may seek to develop in the future will ever obtain the appropriate regulatory approvals necessary for

us to commence product sales. Any delay in obtaining, or an inability to obtain, applicable regulatory approvals would prevent us from commercializing our product candidates, generating revenue and achieving and sustaining profitability.

We cannot commercialize our therapeutic biological product candidates in the United States without first obtaining a regulatory approval for our animal drug candidates, i.e., the genomic modifications to our Tc Bovine, in the form of a NADA. The requirements governing development and approval of a new animal drug are largely analogous to those for new human drugs, requiring a demonstration of the safety and efficacy of the drug for the target indication, a demonstration that the manufacturing facilities, processes and controls are adequate with respect to such product candidate to assure safety, purity and potency, and a review of potential environmental impacts from the altered genomic DNA and the transgenic animals pursuant to the requirements of the NEPA.

The time required to obtain approval for a NADA by the FDA and comparable foreign regulatory authorities is unpredictable. Approval policies, regulations, or the type and amount of data necessary to gain approval is dependent on the specific product candidate and may change during the course of the product candidate’s preclinical and clinical development. Furthermore, we have not obtained regulatory approval for an animal drug, and it is possible that none of our existing animal drug candidates, or any future animal drug candidates, will ever obtain regulatory approval. The reasons our animal drug candidates could fail to receive regulatory approvals are generally the same as the reasons that human drug product candidates may fail to obtain approval. Our failure to obtain a regulatory approval for our animal drug candidates could significantly harm our business, the results of our operations and our prospects. Requests for additional information from a regulatory authority could delay or prevent approval or result in our decision to abandon the development program entirely.

If we do receive regulatory approval of our animal drug candidates, then we will have ongoing responsibilities including registration, recordkeeping, filing supplements, and periodic reporting, which could reveal additional complications and threaten the ongoing approval of our animal drug candidates. Further, as our polyclonal antibody product candidates are regulated as biological products, such product candidates will also require the submission and approval of a BLA prior to marketing. In general, to commercialize any of our product candidates, we must obtain marketing authorization for both the therapeutic antibody product and the altered animal genomic DNA that enables production of the polyclonal antibodies.

If we encounter difficulties enrolling patients in clinical trials, clinical trials of our product candidates may be delayed or otherwise adversely affected.

We may not be able to initiate or continue clinical trials for any product candidate we develop if we are unable to locate and enroll a sufficient number of eligible patients to participate in these trials as required by the FDA or comparable foreign regulatory authorities. The timely completion of clinical trials in accordance with their protocols depends, among other things, on our ability to enroll a sufficient number of patients who remain in the trial until conclusion. We may experience difficulties in patient enrollment in clinical trials for a variety of reasons, including:

•

the size and nature of the patient population;

•

the design of the trial, including the patient eligibility criteria defined in the protocol;

•

the size of the study population required for analysis of the trial’s primary endpoints;

•

the proximity of patients to trial sites;

•

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

•

competing clinical trials for similar therapies or other new therapeutics;

•

clinicians’ and patients’ perceptions as to the potential advantages and side effects of the drug candidate being studied in relation to other available therapies, including any new drugs or treatments that may be approved for the indications we are investigating;

•

our ability to obtain and maintain patient consents;

•

travel restrictions and other potential limitations by federal, state, or local governments affecting the workforce or affecting clinical research site policies implemented in response to public health emergencies that may arise in the future;

•

delays in or temporary suspension of the enrollment of patients in our anticipated clinical trials due to the public health emergencies that may arise in the future;

•

proximity and availability of clinical trial sites for prospective patients;

•

the risk that patients enrolled in clinical trials will not complete a clinical trial; and

•

the availability of approved therapies that are similar in mechanism to our product candidates.

If we experience delays or difficulties in the enrollment of subjects in our anticipated clinical trials, such clinical trials may be delayed or terminated. Even if we are able to enroll a sufficient number of subjects in our future clinical trials, if the pace of enrollment is slower than we expect, the development costs for our product candidates may increase and the completion of such trials may be delayed, or the trials could become too expensive to complete. Our failure to timely complete our current and planned clinical trials would delay the approval and commercialization of our product candidates, impair the commercial performance of our product candidates, may decrease the period of commercial exclusivity and consequently harm our business and results of operations.

To obtain the requisite regulatory approvals for the commercial sale of our product candidates, we must demonstrate through lengthy, complex and expensive preclinical testing and clinical trials that such product candidates are safe, pure and potent 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 begin clinical trials are never approved.

Success in preclinical studies does not ensure that later clinical trials will generate adequate data to demonstrate the efficacy and safety of any product candidate we may develop. Likewise, a number of companies in the pharmaceutical and biotechnology industries, including those with greater resources and experience than us, have suffered significant setbacks in clinical trials, even after seeing promising results in earlier preclinical studies or clinical trials. Despite the results reported in preclinical studies for our product candidates to date, results may not be replicated in subsequent studies, and we do not know whether the clinical trials we may conduct will demonstrate adequate efficacy and safety to support regulatory approval of any current or future product candidate we develop. Moreover, later audits of earlier preclinical data may reveal inaccuracies or deviations impacting the integrity of those data.

Moreover, preclinical and clinical data are often susceptible to varying interpretations and analyses, and many companies that believed their product candidates performed satisfactorily in such studies or trials nonetheless failed to obtain FDA or other necessary regulatory agency approval.

We may fail to demonstrate with substantial evidence from adequate and well-controlled trials, and to the satisfaction of the FDA or comparable foreign regulatory authorities, that our product candidates are safe and potent for their intended uses. If any future late-stage clinical trials we may conduct do not produce favorable results, our ability to achieve regulatory approval for any of our product candidates may be adversely impacted. Even if we believe that we have adequate data to support an application for regulatory approval to market any of our product candidates, the FDA or other regulatory authorities may not agree with our interpretation of the relevant data and may require that we conduct additional preclinical studies or clinical trials to support the regulatory approval of any product candidate that we develop. If we fail to obtain results in our planned and future preclinical and clinical activities and studies sufficient to meet the requirements of the relevant regulatory agencies, the development timeline and regulatory approval and commercialization prospects for any potential product candidate, and, correspondingly, our business and financial prospects, would be materially adversely affected.

We have not completed the development of any product candidates. Our future success and ability to generate revenue from our product candidates, which we do not expect will occur for several years, if ever, is dependent on our ability to successfully develop, obtain regulatory approval for and commercialize one or more of our product candidates. All of our product candidates, including our lead product candidate SAB-142, are in early stages of development and require substantial additional investment for clinical development, regulatory review and approval in one or more jurisdictions. If any of our product candidates encounters safety or efficacy problems, development delays or regulatory issues or other problems, our development plans and business would be materially harmed.

All of our other product candidates are in earlier stages of development and will require substantial additional investment for clinical development, regulatory review and approval in one or more jurisdictions. If any of our product candidates encounters safety or efficacy problems, development delays or regulatory issues or other problems, our development plans and business would be materially harmed.

We may not have the financial resources to continue development of our product candidates if we experience any issues that delay or prevent regulatory approval of, or our ability to commercialize, our product candidates, including:

•

our inability to demonstrate to the satisfaction of the FDA or comparable foreign regulatory authorities that our product candidates are safe and effective;

•

insufficiency of our financial and other resources to complete the necessary clinical trials and preclinical studies;

•

negative or inconclusive results from our clinical trials, preclinical studies or the clinical trials of others for product candidates similar to ours, leading to a decision or requirement to conduct additional clinical trials or preclinical studies or abandon a program;

•

product-related adverse events experienced by subjects in our clinical trials, including unexpected toxicity results, or by individuals using drugs or therapeutic biologics similar to our product candidates;

•

delays in submitting an INAD or IND or comparable foreign applications or delays or failure in obtaining the necessary approvals from regulators to commence a clinical trial or a suspension or termination, or hold, of a clinical trial once commenced;

•

conditions imposed by the FDA or comparable foreign regulatory authorities regarding the scope or design of our clinical trials;

•

poor effectiveness of our product candidates during clinical trials;

•

delays in enrolling subjects in our clinical trials;

•

higher than anticipated clinical trial or manufacturing costs;

•

failure of our third-party contractors or investigators to comply with regulatory requirements or the clinical trial protocol or otherwise meet their contractual obligations in a timely manner, or at all; and

•

delays and changes in regulatory requirements, policy and guidelines, including the imposition of additional regulatory oversight around clinical testing generally or with respect to our therapies in particular.

Our wholly-owned Australian subsidiary, SAB Australia, was formed to conduct various preclinical and clinical activities for SAB-142 and other future drug candidates in Australia. Due to the geographical distance and lack of employees currently in Australia, as well as our lack of experience operating in Australia, we may not be able to efficiently or successfully monitor, develop and commercialize our lead products in Australia, including conducting clinical trials. Furthermore, we have no assurance that the results of any clinical trials that we conduct for our product candidates in Australia will be accepted by the FDA or applicable foreign authorities.

In addition, current Australian tax regulations provide for a refundable research and development tax credit equal to 48.5% of qualified expenditures. Although we have previously claimed a refundable research and development tax credit there is a possibility that we may not be able to claim such credit, or we might qualify for a lesser credit. If we lose our ability to operate SAB Australia, or if in the future we are ineligible or unable to receive the research and development tax credit or are required to refund any research and development tax credit previously received or have to reserve for such credit in our financial statements, or if the Australian government significantly reduces or eliminates the tax credit, our business and results of operation may be adversely affected.

We are not permitted to commercialize, market, promote or sell any product candidate in the United States without obtaining regulatory approval from the FDA. The time required to obtain approval by the FDA and comparable foreign authorities is inherently unpredictable, but typically takes many years following the commencement of clinical trials and depends upon numerous factors, including substantial discretion of the regulatory authorities. In addition, approval policies, regulations, or 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. To date, we have not submitted a NADA or BLA to the FDA or

similar drug or biological product approval submissions to comparable foreign regulatory authorities for any product candidate.

In addition to regulations in the United States, to market and sell our product candidates in the European Union, many Asian countries and other jurisdictions, we must obtain separate regulatory approvals and comply with numerous and varying regulatory requirements, both from a clinical and manufacturing perspective. The approval procedure for complex therapeutic biological product candidates such as ours varies among countries and can involve additional testing and validation and additional administrative review periods. The time required to obtain approval may differ substantially from that required to obtain FDA approval. The regulatory approval process outside the United States generally includes all of the risks associated with obtaining FDA approval. Clinical trials accepted in one country may not be accepted by regulatory authorities in other countries.

In addition, many countries outside the United States require that a product be approved for reimbursement before it can be approved for sale in that country. A product candidate that has been approved for sale in a particular country may not receive reimbursement approval in that country. We may not be able to obtain approvals from regulatory authorities or payor authorities outside the United States on a timely basis, if at all. Approval by the FDA does not ensure approval by regulatory or payor authorities in other countries or jurisdictions, and approval by one regulatory or payor authority outside the United States does not ensure approval by regulatory authorities in other countries or jurisdictions or by the FDA. We may not be able to file for future regulatory approvals and may not receive necessary approvals to commercialize our products in any market. If we are unable to obtain approval of any of our product candidates by regulatory or payor authorities in the European Union, Asia or elsewhere, the commercial prospects of that product candidate may be significantly diminished. We do not have any product candidates approved for sale in any jurisdiction, including in the United States or in international markets, and we 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 international markets are delayed, our target market will be reduced and our ability to realize the full market potential of our products will be unrealized.

The FDA or comparable foreign regulatory authorities may disagree with our regulatory plan for our product candidates.

The general approach for FDA approval of a new drug is dispositive data from two or more well-controlled Phase 3 clinical trials of the product candidate in the relevant patient population. Phase 3 clinical trials typically involve a large number of patients, have significant costs and take years to complete. In addition, there is no assurance that the endpoints and trial designs that we intend to use for our planned clinical trials, including those that we have developed based on feedback from regulatory agencies or those that have been used for the approval of similar drugs, will be acceptable for future approvals. Our clinical trial results may not support approval of our product candidates. In addition, our product candidates could fail to receive regulatory approval, or regulatory approval could be delayed, for many reasons, including the following:

•

the FDA or comparable foreign regulatory authorities may not file or accept our NADA, BLA or other marketing applications for substantive review;

•

the FDA or comparable foreign regulatory authorities may disagree with the dosing regimen, design or implementation of our clinical trials;

•

we may be unable to demonstrate to the satisfaction of the FDA or comparable foreign regulatory authorities that our product candidates are safe and effective for any of their proposed indications;

•

the results of our clinical trials may not meet the level of statistical significance required by the FDA or comparable foreign regulatory authorities for approval;

•

we may be unable to demonstrate that our product candidates’ clinical and other benefits outweigh their safety risks;

•

the data collected from clinical trials of our product candidates may not be sufficient to the satisfaction of the FDA or comparable foreign regulatory authorities to support the submission of a NADA, BLA or other comparable submissions in foreign jurisdictions or to obtain regulatory approval in the United States or elsewhere;

•

the FDA or comparable foreign regulatory authorities may find deficiencies with or 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 or comparable foreign regulatory authorities may significantly change in a manner rendering our clinical data insufficient for approval.

The results observed from preclinical studies or early-stage clinical trials of our product candidates may not necessarily be predictive of the results of later-stage clinical trials that we conduct. Similarly, positive results from such preclinical studies or early-stage clinical trials may not be replicated in our subsequent preclinical studies or clinical trials. There can be no assurance that any of our clinical trials will ultimately be successful or support further clinical development of any of our product candidates. There is a high failure rate for drugs proceeding through clinical trials. Many companies in the pharmaceutical and biotechnology industries have suffered significant setbacks in late-stage clinical trials after achieving positive results in early-stage development, and we cannot be certain that we will not face similar setbacks. These setbacks have been caused by, among other things, preclinical findings made while clinical trials were underway or safety or efficacy observations made in preclinical studies and clinical trials, including previously unreported adverse events.

We may incur unexpected costs or experience delays in completing, or ultimately be unable to complete, the development and commercialization of our product candidates.

To obtain the requisite regulatory approvals to commercialize any of our product candidates, we must demonstrate through extensive preclinical studies and clinical trials that our product candidates are safe and effective in humans. We may experience delays in completing our clinical trials or preclinical studies and initiating or completing additional clinical trials or preclinical studies, including as a result of regulators not allowing or delay in allowing clinical trials to proceed under an INAD or IND, or not approving or delaying approval for any clinical trial grant or similar approval we need to initiate a clinical trial. We may also experience numerous unforeseen events during our clinical trials that could delay or prevent our ability to receive marketing approval or commercialize the product candidates we develop, including:

•

regulators, institutional review boards (IRBs), or other reviewing bodies may not authorize us or our investigators to commence a clinical trial, or to conduct or continue a clinical trial at a prospective or specific trial site;

•

we may not reach agreement on acceptable terms with prospective contract research organizations (CROs), and clinical trial sites, the terms of which can be subject to extensive negotiation and may vary significantly among different CROs and trial sites;

•

we may experience challenges or delays in recruiting principal investigators or study sites to lead our clinical trials;

•

the number of subjects or patients required for clinical trials of our product candidates may be larger than we anticipate, enrollment in these clinical trials may be insufficient or slower than we anticipate, and the number of clinical trials being conducted at any given time may be high and result in fewer available patients for any given clinical trial, or patients may drop out of these clinical trials at a higher rate than we anticipate;

•

our third-party contractors, including those manufacturing our product candidates or conducting clinical trials on our behalf, may fail to comply with regulatory requirements or meet their contractual obligations to us in a timely manner, or at all;

•

we may have to amend clinical trial protocols submitted to regulatory authorities or conduct additional studies to reflect changes in regulatory requirements or guidance;

•

regulators or other reviewing bodies may find deficiencies with, fail to approve or subsequently find fault with the manufacturing processes or facilities of third-party manufacturers with which we enter into agreements for clinical and commercial supplies, or the supply or quality of any product candidate or other materials necessary to conduct clinical trials of our product candidates may be insufficient, inadequate or not available at an acceptable cost, or we may experience interruptions in supply; and

•

the potential for approval policies or regulations of the FDA or the applicable foreign regulatory agencies to significantly change in a manner rendering our clinical data insufficient for approval.

Regulators or IRBs of the institutions in which clinical trials are being conducted may suspend, limit or terminate a clinical trial, or data monitoring committees may recommend that we suspend or terminate a clinical trial, due to a number of factors,

including failure to conduct the clinical trial in accordance with regulatory requirements or our clinical protocols, inspection of the clinical trial operations or trial site by the FDA or other regulatory authorities resulting in the imposition of a clinical hold, safety issues or adverse side effects, failure to demonstrate a benefit from using an investigational product, changes in governmental regulations or administrative actions or lack of adequate funding to continue the clinical trial. Negative or inconclusive results from our clinical trials or preclinical studies could mandate repeated or additional clinical trials and, to the extent we choose to conduct clinical trials in other indications, could result in changes to or delays in clinical trials of our product candidates in such other indications. We do not know whether any clinical trials that we conduct will demonstrate adequate efficacy and safety to result in regulatory approval to market our product candidates for the indications that we are pursuing. If later-stage clinical trials do not produce favorable results, our ability to obtain regulatory approval for our product candidates will be adversely impacted.

Any product candidate we develop, and the activities associated with its development and commercialization, including its design, testing, manufacture, safety, efficacy, recordkeeping, labeling, storage, approval, advertising, promotion, sale, and distribution, are subject to comprehensive regulation by the FDA and other regulatory authorities in the United States and by comparable authorities in other countries. Failure to obtain marketing approval for a product candidate will prevent us from commercializing the product candidate in a given jurisdiction. We have not received approval to market any product candidates from regulatory authorities in any jurisdiction and it is possible that none of the product candidates we are developing or may seek to develop in the future will ever obtain regulatory approval.

We have no experience in submitting and supporting the applications necessary to gain marketing approvals and expect to rely on third-party CROs or regulatory consultants to assist us in this process. Securing regulatory approval requires the submission of extensive preclinical and clinical data and supporting information to the various regulatory authorities for each therapeutic indication to establish the product candidate’s safety and efficacy. Securing regulatory approval also requires the submission of information about the product manufacturing process to, and successful inspection of manufacturing facilities by, the relevant regulatory authority. Any product candidates we develop may not be effective, may be only moderately effective, or may prove to have undesirable or unintended side effects, toxicities or other characteristics that may preclude its obtaining marketing approval or prevent or limit commercial use.

The process of obtaining marketing approvals, both in the United States and abroad, is expensive, may take many years if additional clinical trials are required, if approval is obtained at all, and can vary substantially based upon a variety of factors, including the type, complexity, and novelty of the product candidates involved. Changes in marketing approval policies during the development period, changes in or the enactment of additional statutes or regulations, or changes in regulatory review for each submitted product application, may cause delays in the approval or rejection of an application. The FDA and comparable authorities in other countries have substantial discretion in the approval process and may refuse to accept any application or may decide that our data are insufficient for approval and require additional preclinical, clinical or other studies. In addition, varying interpretations of the data obtained from preclinical and clinical testing could delay, limit, or prevent marketing approval of a product candidate. Any marketing approval that we may ultimately obtain could be limited or subject to restrictions or post-approval commitments that render the approved product not commercially viable.

Interim, topline and preliminary data from our clinical trials that we announce or publish from time to time may change as more patient data becomes 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, topline or preliminary data from our clinical trials. Interim data 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 or topline data 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, interim and preliminary data should be viewed with caution until the final data are available. Adverse differences between preliminary or interim data and final data could significantly harm our reputation and business prospects.

For planning purposes, we sometimes estimate the timing of the accomplishment of various scientific, clinical, regulatory and other product development objectives. These milestones may include our expectations regarding the commencement or completion of scientific studies and clinical trials, the submission of regulatory filings or commercialization objectives. From time to time, we may publicly announce the expected timing of some of these milestones, such as the completion of an ongoing clinical trial, the initiation of other clinical programs, receipt of marketing approval or a commercial launch of a product. The achievement of many of these milestones may be outside of our control. All of these milestones are based on a variety of assumptions which, if not realized as expected, may cause the timing of achievement of the milestones to vary considerably from our estimates, including:

•

our available capital resources or capital constraints we experience;

•

the rate of progress, costs and results of our clinical trials and research and development activities, including the extent of scheduling conflicts with participating clinicians and collaborators;

•

our ability to identify and enroll patients who meet clinical trial eligibility criteria;

•

our receipt of approvals by the FDA and other regulatory authorities and the timing thereof;

•

other actions, decisions or rules issued by regulators;

•

our ability to access sufficient, reliable and affordable supplies of materials used to manufacture of our product candidates;

•

the efforts of our collaborators with respect to the commercialization of our product candidates; and

•

the securing of costs related to, and timing issues associated with, product manufacturing as well as sales and marketing activities.

If we fail to achieve announced milestones in the timeframes we expect, the development and commercialization of our product candidates may be delayed, and our business and results of operations may be harmed.

Changes in methods of product candidate manufacturing or formulation may result in additional costs or delays.

As product candidates proceed through preclinical studies to late-stage clinical trials towards potential approval 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. Such changes carry the risk that they will not achieve these intended objectives. Any of these changes could cause our product candidates to perform differently and affect the results of planned clinical trials or other future clinical trials conducted with the materials manufactured using altered processes. Such changes may also require additional testing, FDA notification or FDA approval. This could delay or prevent completion of clinical trials, require conducting bridging clinical trials or the repetition of one or more clinical trials, increase clinical trial costs, delay or prevent approval of our product candidates and jeopardize our ability to commence sales and generate revenue.

Undesirable side effects caused by any of our product candidates could cause us or regulatory authorities to interrupt, delay or halt clinical trials and could result in a more restrictive label or the delay or denial of regulatory approval by the FDA or comparable foreign regulatory authorities or a more restrictive label for any of our product candidates that may receive regulatory approval. In our planned and future clinical trials of our product candidates, we may observe a more unfavorable safety and tolerability profile than was observed in earlier-stage testing of these candidates.

If unacceptable side effects arise in the development of our product candidates, we, the FDA or comparable foreign regulatory authorities, the IRBs, or independent ethics committees at the institutions in which our trials are conducted, could suspend, limit or terminate our clinical trials, or the independent safety monitoring committee could recommend that we suspend, limit or terminate our trials, or the FDA or comparable foreign regulatory authorities could order us to cease clinical trials or deny approval of our product candidates for any or all targeted indications. Treatment-emergent side effects that are deemed to be related to administration of our product candidates could delay recruitment of clinical trial subjects or may cause subjects that enroll in our clinical trials to discontinue participation in our clinical trials. In addition, these side effects may not be appropriately recognized or managed by the treating medical staff. We may need to train medical personnel using our product candidates to understand the side effect profiles for our clinical trials and upon any commercialization of any of

our product candidates. Inadequate training in recognizing or managing the potential side effects of our product candidates could result in harm to patients that are administered our product candidates.

Additionally, during the course of our product development programs, FDA or comparable foreign regulatory authority review teams may change, and new agency personnel may view the risk-benefit profile of any product candidates we may develop differently than prior agency review teams. Any negative views as to the risk-benefit profile of the product candidates we are developing for our lead programs or any product candidates we may develop in the future could lead FDA or comparable foreign regulatory authorities to require that we conduct additional clinical trials or could require more onerous clinical trial designs for any then-ongoing or future clinical trials. The product-related side effects also could result in potential product liability claims being asserted against us. Furthermore, we or others may later identify undesirable side effects caused by our products, including during any long-term follow-up observation period.

If any of our product candidates receives regulatory approval, and we or others later identify undesirable side effects caused or risks exacerbated by such product, a number of potentially significant negative consequences could result. For example, the FDA could require us to adopt a REMS to ensure that the benefits of treatment with such product candidate outweigh the risks for each potential patient; a REMS may include, among other things, a communication plan to healthcare practitioners, patient education, extensive patient monitoring or distribution systems and processes that are highly controlled, restrictive and more costly than what is typical for the biopharmaceutical industry. Other potentially significant negative consequences include that:

•

we may be forced to suspend marketing of that product, or decide to recall the product or remove it from the marketplace;

•

regulatory authorities may withdraw or limit their approvals of that product;

•

regulatory authorities may require additional statements, specific warnings or contraindications on the label or limit access of that product to selective specialized centers with additional safety reporting and with requirements that patients be geographically close to these centers for all or part of their treatment;

•

we may be required to conduct additional clinical trials or costly post-marketing testing and surveillance to monitor the safety and efficacy of the product;

•

we may be required to change the way the product is distributed or administered;

•

we may be subject to regulatory investigations and government enforcement actions;

•

we could be subject to fines, injunctions, or the imposition of criminal or civil penalties, or to sued and held liable for harm caused to subjects or patients; and

•

the product may become less competitive, and our reputation may suffer.

Any of these occurrences could diminish the usage or otherwise limit the commercial success of our product candidates and prevent us from achieving or maintaining market acceptance of the affected product candidate, if approved by applicable regulatory authorities, and may adversely affect our business, financial condition and prospects significantly.

When available on the market, our products may not achieve an adequate level of acceptance by physicians, patients and the medical community, which may result in us failing to achieve profitability. In addition, efforts to educate the medical community and third-party payers on the benefits of our products may require significant resources and may never be successful, which would prevent us from generating significant revenues or becoming profitable.

Failure to successfully identify, develop and commercialize additional products or product candidates could impair our ability to grow.

Although a substantial amount of our efforts will focus on the continued preclinical and clinical testing and potential approval of product candidates in our current pipeline, a key element of long-term growth strategy is to develop and market additional products and product candidates. Because we have limited financial and managerial resources, research programs to identify product candidates will require substantial additional technical, financial and human resources, whether or not any product candidates are ultimately identified. The success of this strategy depends partly upon our ability to identify, select and develop promising product candidates and products. Our technology platforms may fail to discover and to generate additional product candidates that are suitable for further development. All product candidates are prone to risks of failure typical of pharmaceutical product development, including the possibility that a product candidate may not be suitable for clinical development as a result of its harmful side effects, limited efficacy or other characteristics that indicate that it is unlikely to be a product that will receive approval by the FDA and other comparable foreign regulatory authorities and achieve market

acceptance. If we do not successfully develop and commercialize product candidates based upon its technological approach, we may not be able to obtain product or collaboration revenues in future periods, which would adversely affect our business, prospects, financial condition and results of operations.

Our long-term growth strategy to develop and market additional products and product candidates is heavily dependent on precise, accurate and reliable scientific data to identify, select and develop promising pharmaceutical product candidates and products. Our business decisions may therefore be adversely influenced by improper or fraudulent scientific data sourced from third parties. Any irregularities in the scientific data used by us to determine our focus in research and development of product candidates and products could have a material adverse effect on our business, prospects, financial condition and results of operations.

We currently have no marketing, sales or distribution capabilities. We intend to establish a sales and marketing organization, either on our own or in collaboration with third parties, with technical expertise and supporting distribution capabilities to commercialize SAB-142, and our other product candidates that may receive regulatory approval in key territories. These efforts will require substantial additional resources, some or all of which may be incurred in advance of any approval of the product candidate. Any failure or delay in the development of our or third parties’ internal sales, marketing and distribution capabilities would adversely impact the commercialization of SAB-142, and our other product candidates and other future product candidates.

Factors that may inhibit our efforts to commercialize our product candidates on our own include:

•

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

•

our inability of sales personnel to obtain access to or persuade adequate numbers of physicians to prescribe any future products;

•

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

•

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

With respect to our existing and future product candidates, we may choose to collaborate with third parties that have direct sales forces and established distribution systems to serve as an alternative to our own sales force and distribution systems. Our future product revenue may be lower than if we directly marketed or sold our product candidates, if approved. In addition, any revenue we receive will depend in whole or in part upon the efforts of these third parties, which may not be successful and are generally not within our control. If we are not successful in commercializing any approved products, our future product revenue will suffer, and we may incur significant additional losses.

If we do not establish sales and marketing capabilities successfully, either on our own or in collaboration with third parties, we will not be successful in commercializing our product candidates.

We are exposed to potential product liability and professional indemnity risks that are inherent in the research, development, manufacturing, marketing and use of pharmaceutical products. Currently, we have no products that have been approved for commercial sale; however, the use of our product candidates by us and any collaborators in clinical trials, and the sale of these product candidates, if approved, in the future, may expose us to liability claims. We face an inherent risk of product liability lawsuits related to the use of our product candidates in patients, and will face an even greater risk if product candidates are approved by regulatory authorities and introduced commercially. Product liability claims may be brought against us by participants enrolled in our clinical trials, patients, health care providers, pharmaceutical companies, our collaborators or others using, administering or selling any of our future approved products. If we cannot successfully defend ourselves against any such claims, we may incur substantial liabilities or be required to limit commercialization of our product candidates. Regardless of the merits or eventual outcome, liability claims may result in:

•

decreased demand for any of our future approved products;

•

injury to our reputation;

•

withdrawal of clinical trial participants;

•

termination of clinical trial sites or entire trial programs;

•

significant litigation costs;

•

substantial monetary awards to, or costly settlements with, patients or other claimants;

•

product recalls or a change in the indications for which they may be used;

•

loss of revenue;

•

diversion of management and scientific resources from our business operations; and

•

the inability to commercialize our product candidates.

Although the clinical trial process is designed to identify and assess potential side effects, clinical development does not always fully characterize the safety and efficacy profile of a new medicine, and it is always possible that a drug, even after regulatory approval, may exhibit unforeseen side effects. If our product candidates were to cause adverse side effects during clinical trials or after approval, we may be exposed to substantial liabilities. Physicians and patients may not comply with any warnings that identify known potential adverse effects and patients who should not use our product candidates. If any of our product candidates are approved for commercial sale, we will be highly dependent upon consumer perceptions of us and the safety and quality of our products. We could be adversely affected if we are subject to negative publicity associated with illness or other adverse effects resulting from patients’ use or misuse of our products or any similar products distributed by other companies.

Although we maintain product liability insurance coverage consistent with industry norms, including clinical trial liability, this insurance may not fully cover potential liabilities that we may incur. The cost of any product liability litigation or other proceeding, even if resolved in our favor, could be substantial. We will need to increase our insurance coverage if we commercialize any product that receives regulatory approval. In addition, insurance coverage is becoming increasingly expensive. If we are unable to maintain sufficient insurance coverage at an acceptable cost or to otherwise protect against potential product liability claims, it could prevent or inhibit the development and commercial production and sale of our product candidates, which could harm our business, financial condition, results of operations and prospects.

Our current and future relationships with customers and third-party payors in the United States and elsewhere may be subject, directly or indirectly, to applicable anti-kickback, fraud and abuse, false claims, transparency, health information privacy and security and other healthcare laws and regulations, which could expose us to criminal sanctions, civil penalties, contractual damages, reputational harm, administrative burdens and diminished profits and future earnings.

Healthcare providers, physicians and third-party payors in the United States and elsewhere will play a primary role in the recommendation and prescription of any product candidates for which we obtain marketing approval. Our future arrangements with third party payors, distributors, retailers, marketers and customers may expose us to broadly applicable fraud and abuse and other healthcare laws and regulations, including, without limitation, the federal Anti-Kickback Statute, the federal False Claims Act, and similar state or foreign laws which may constrain the business or financial arrangements and relationships through which we sell, market and distribute any product candidates for which we obtain marketing approval. In addition, we may be subject to transparency laws and patient privacy regulation by U.S. federal and state governments and by governments in foreign jurisdictions in which we conduct our business. The applicable federal, state and foreign healthcare laws and regulations that may affect our ability to operate include, but are not necessarily limited to:

•

the federal Anti-Kickback Statute, which prohibits, among other things, persons from knowingly and willfully soliciting, offering, receiving or providing remuneration, directly or indirectly, in cash or in kind, to induce or reward, or in return for, either the referral of an individual for, or the purchase, order or recommendation of, any good or service, for which payment may be made under federal and state healthcare programs, such as Medicare and Medicaid;

•

federal civil and criminal false claims laws and civil monetary penalty laws, including the federal False Claims Act, which impose criminal and civil penalties, including civil whistleblower or qui tam actions, against individuals or entities for knowingly presenting, or causing to be presented, to the federal government, including the Medicare and Medicaid programs, claims for payment that are false or fraudulent, making a false statement to avoid, decrease or conceal an obligation to pay money to the federal government, or the knowing retention of an overpayment from government health care programs; the federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, which imposes criminal and civil liability for executing a scheme to defraud any healthcare benefit program or making false statements relating to healthcare matters;

•

HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act of 2009, or HITECH, and their respective implementing regulations, which impose obligations on covered healthcare providers, health plans, and healthcare clearinghouses, as well as their business associates that create, receive, maintain or transmit individually identifiable health information for or on behalf of a covered entity, with respect to safeguarding the privacy, security and transmission of individually identifiable health information;

•

the federal Physician Payments Sunshine Act, which requires manufacturers of certain drugs, devices, biologics and medical supplies for which payment is available under Medicare, Medicaid or the Children’s Health Insurance Program, with specific exceptions, to report annually to the Centers for Medicare & Medicaid Services, or CMS, information related to “payments or other transfers of value” made to physicians, which is defined to include doctors, dentists, optometrists, podiatrists and chiropractors, and certain teaching hospitals and applicable manufacturers to report annually to CMS ownership and investment interests held by the physicians and their immediate family members. Certain manufacturers also are required to report such information regarding payments and transfers of value provided during the previous year to physician assistants, nurse practitioners, clinical nurse specialists, anesthesiologist assistants, certified nurse anesthetists and certified nurse-midwives; and

•

analogous state and foreign laws and regulations, such as state anti-kickback and false claims laws, which may apply to sales or marketing arrangements and claims involving healthcare items or services reimbursed by non-governmental third party payors, including private insurers; state and foreign laws that require pharmaceutical companies to comply with the pharmaceutical industry’s voluntary compliance guidelines and the relevant compliance guidance promulgated by the federal government or otherwise restrict payments that may be made to healthcare providers; 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 or marketing expenditures; and state and foreign laws governing the privacy and security of health information in certain circumstances, many of which differ from each other in significant ways and often are not preempted by HIPAA, thus complicating compliance efforts.

Efforts to ensure that our business arrangements with third parties will comply with applicable healthcare laws and regulations may involve substantial costs. It is possible that governmental authorities will conclude that our business practices may 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 other governmental regulations that may apply to us, we may be subject to significant civil, criminal and administrative penalties, including, without limitation, damages, fines, imprisonment, exclusion from participation in government healthcare programs, such as Medicare and Medicaid, and the curtailment or restructuring of our operations, which could have a material adverse effect on our business. If any of the physicians or other healthcare providers or entities with whom we expect to do business, including our collaborators, is found not to be in compliance with applicable laws, it may be subject to criminal, civil or administrative sanctions, including exclusions from participation in government healthcare programs, which could also materially affect our business.

Regulatory approval for any approved product is limited by the FDA to those specific indications and conditions for which clinical safety and efficacy have been demonstrated.

Any regulatory approval is limited to those specific diseases and indications for which a product is deemed to be safe and effective by the FDA. In addition to the FDA approval required for new formulations, any new indication for an approved product also requires FDA approval. If we are not able to obtain FDA approval for any desired future indications for our products, our ability to effectively market and sell our products may be reduced and our business may be adversely affected.

While our ability to promote the products is limited to those indications that are specifically approved by the FDA, physicians may choose to prescribe drugs for uses that are not described in the product’s approved labeling and for uses that differ from those tested in clinical studies and approved by the regulatory authorities. These “off-label” uses are common across medical specialties and may constitute an appropriate treatment for some patients in varied circumstances. Regulatory authorities in the United States generally do not regulate a physician’s use of professional judgment in prescribing treatments for patients. Regulatory authorities do, however, restrict communications by pharmaceutical companies on the subject of off-label use or off-label information. If our promotional activities fail to comply with these regulations or guidelines, we may be subject to warnings from, or enforcement action by, these authorities. In addition, our failure to follow FDA rules and guidelines relating to promotion and advertising may cause the FDA to suspend or withdraw an approved product from the market, require a recall or corrective advertising, institute fines, or could result in disgorgement of money, operating restrictions, injunctions or civil or criminal prosecution by the government, any of which could harm our reputation and business.

In the United States and certain non-U.S. jurisdictions, there have been, and we expect there will continue to be, a number of legislative and regulatory changes and proposed changes regarding the healthcare system that could, among other things,

prevent or delay marketing approval of our product candidates, restrict or regulate post-approval activities and affect our or our collaborators’ ability to profitably sell any product candidates that obtain marketing approval.

For example, in March 2010, the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act, collectively the Affordable Care Act, was enacted in the United States.

Since its enactment, there have been judicial, executive and Congressional challenges to certain aspects of the Affordable Care Act. However, following several years of litigation in the federal courts, in June 2021, the U.S. Supreme Court upheld the ACA when it dismissed a legal challenge to the ACA’s constitutionality. Further legislative and regulatory changes under the ACA remain possible, but it is unknown what form any such changes or any law would take or how or whether such changes may affect the biopharmaceutical industry as a whole or our business in the future.

In addition, other legislative changes have been proposed and adopted since the Affordable Care Act was enacted. On August 2, 2011, the Budget Control Act of 2011 was signed into law, which, among other things, included 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 to the statute, will remain in effect through 2030, unless additional Congressional action is taken. On January 2, 2013, the American Taxpayer Relief 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 from three to five years.

Further, there has been heightened governmental scrutiny recently over pharmaceutical pricing practices in light of the rising cost of prescription drugs and biologics. Such scrutiny has resulted in several Congressional inquiries and proposed and enacted federal and state legislation designed to, among other things, bring more transparency to product pricing, review the relationship between pricing and manufacturer patient programs, and reform government program reimbursement methodologies, rebates and price negotiation for pharmaceutical products. At the state level, legislatures have increasingly passed legislation and implemented regulations designed to control pharmaceutical product and medical device 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 other countries and bulk purchasing. In addition, regional healthcare authorities and individual hospitals are increasingly using bidding procedures to determine what pharmaceutical products and medical devices to purchase, and which suppliers will be included in their prescription drug and other healthcare programs.

We expect that other healthcare reform measures that may be adopted in the future, may result in more rigorous coverage criteria, new payment methodologies and in additional downward pressure on the price that we or our collaborators may receive for any approved or cleared product. Any reduction in reimbursement from Medicare or other government programs may result in a similar reduction in payments from private payors. We cannot predict the likelihood, nature or extent of government regulation that may arise from future legislation or administrative action, either in the United States or abroad. If we or our collaborators are slow or unable to adapt to new requirements or policies, or if we or our collaborators are not able to maintain regulatory compliance, any of our product candidates may lose any regulatory approval that may have been obtained and we may not achieve or sustain profitability, which would adversely affect our business.

Even if we obtain regulatory approval for our product candidates, our products will remain subject to regulatory scrutiny.

Even if we obtain regulatory approval in a jurisdiction for our product candidates, they will be subject to ongoing regulatory requirements for manufacturing, labeling, packaging, storage, advertising, promotion, sampling, recordkeeping, and submission of safety and other post-market information. Any regulatory approvals that we receive for our product candidates may also be subject to limitations on the approved indicated uses for which the product may be marketed or to the conditions of approval, or contain requirements for potentially costly post-marketing testing, including Phase 4 clinical trials, and surveillance to monitor the safety and efficacy of the product. For example, the holder of an approved BLA is obligated to monitor and report adverse events and any failure of a product to meet the specifications in the BLA. The holder of an approved BLA must also submit new or supplemental applications and obtain FDA approval for certain changes to the approved product, product labeling or manufacturing process. Advertising and promotional materials and claims must be consistent with approved labeling and be in compliance with FDA regulations as well as other potentially applicable federal and state laws. In addition, biological product advertising and promotional materials intended to be used during the first 120 days after approval must be submitted to the FDA during the BLA review period. After approval, advertising and promotional materials must be submitted to the FDA 30 days prior to their intended use.

In addition, product manufacturers are subject to payment of program fees and continual review and periodic inspections by the FDA and other regulatory authorities for compliance with GMP requirements and adherence to commitments made in the BLA or foreign marketing application. If we or a regulatory agency discovers previously unknown problems with a product such as adverse events of unanticipated severity or frequency, or problems with the facility where the product is manufactured or with the integrity or sufficiency of data, records, or documentation, or disagrees with the promotion,

marketing or labeling of that product, a regulatory agency may impose restrictions relative to that product, the manufacturing facility or us, including requiring recall or withdrawal of the product from the market or suspension of manufacturing.

If we or a regulatory agency later discovers previously unknown problems with a product, including adverse events of unanticipated severity or frequency, or with our third-party manufacturers or manufacturing processes, or if we fail to comply with applicable regulatory requirements following approval of any of our product candidates, a regulatory agency may:

•

issue a warning letter asserting that we are in violation of the law;

•

seek an injunction or impose civil or criminal penalties or monetary fines;

•

suspend or withdraw regulatory approval;

•

suspend any ongoing clinical trials;

•

refuse to approve a pending BLA or comparable foreign marketing application (any supplements thereto) submitted by us or our strategic partners;

•

restrict the marketing or labeling of the product;

•

restrict manufacturing of the product, the approved manufacturers or the manufacturing process;

•

restrict product distribution or use;

•

demand a recall;

•

seize or detain product or otherwise require the withdrawal of product from the market;

•

impose fines, restitution or disgorgement of profits or revenues;

•

impose consent decrees, injunctions or the imposition of civil or criminal penalties;

•

refuse to permit the import or export of products; or

•

refuse to allow us to enter into supply contracts, including government contracts.

Any government investigation of alleged violations of law could require us to expend significant time and resources in response and could generate negative publicity. The occurrence of any event or penalty described above may inhibit our ability to commercialize our product candidates and generate revenue.

Advertising and promotion of any human therapeutic biological product candidate that obtains approval in the United States will be heavily scrutinized by the FDA, the U.S. Federal Trade Commission, the Department of Justice (DOJ), the Office of Inspector General of the Department of Health and Human Services (HHS), state attorneys general, members of the U.S. Congress and the public. Additionally, advertising and promotion of any product candidate that obtains approval outside of the United States will be heavily scrutinized by comparable foreign entities and stakeholders. Violations, including actual or alleged promotion of our products for unapproved or off-label uses, are subject to enforcement letters, inquiries and investigations, and civil and criminal sanctions by the FDA, other U.S. governmental authorities, or comparable foreign bodies. Any actual or alleged failure to comply with labeling and promotion requirements may result in fines, warning letters, mandates to issue corrective information to healthcare practitioners and/or the general public, injunctions, or civil or criminal penalties.

In addition, the FDA’s policies may change, and additional government laws may be enacted and implementing regulations promulgated, which could prevent, limit or delay regulatory approval of our product candidates. We cannot predict the likelihood, nature or extent of government regulation that may arise from future legislation or administrative action, either in the United States or abroad. 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 may have obtained and we may not achieve or sustain profitability, which would adversely affect our business, prospects, financial condition and results of operations.

A prolonged U.S. federal government shutdown could materially and adversely affect our business, operations, and legal proceedings.

On October 1, 2025, the federal government of the United States began a shutdown at 12:01 a.m. EDT as a result of congressional failure to pass appropriations legislation for the 2026 fiscal year, which began that day, and lasted for 43 days. Subsequent partial federal government shutdowns occurred in January and February of 2026. A continued and prolonged shutdown could materially and adversely affect our business, operations, financial condition, and legal matters. A federal government shutdown may result in the furlough of federal employees, reduced availability of government services, and suspension or delay of activities by key agencies that regulate, fund, or interact with our business, including the SEC, the FDA, the HHS, and the U.S. Patent and Trademark Office. During such periods, review and approval of our filings, applications, and submissions could be delayed, and we may be unable to access or rely upon certain government data or

systems. In addition, the Administrative Office of the U.S. Courts and federal judiciary operations rely on appropriated funds and fee-based reserves that may be exhausted in the event of an extended shutdown. If federal court funding lapses or is limited to “essential” functions only, civil litigation, bankruptcy proceedings, and regulatory enforcement actions involving us or our affiliates could be postponed or suspended. Any such delay could impede our ability to resolve disputes, enforce contractual rights, or obtain timely judicial relief, which may have a material adverse effect on our financial position or prospects. Such conditions could negatively impact our access to financing, timing of capital-raising transactions, and the liquidity or trading volume of our securities. Accordingly, the federal government shutdown, or uncertainty regarding the continuity of government operations could have a material adverse effect on our business, results of operations, and stock price.

Unfavorable global economic conditions and government regulations could adversely affect our business, financial condition or results of operations.

Our results of operations could be adversely affected by general conditions in the global economy and in the global financial markets. Factors such as geopolitical events (including the ongoing wars in Iran, Ukraine and Israel and the risk of increased tensions between China and Taiwan), inflationary pressures, public health crises, and U.S. election cycles, and changes in government administration and policies have caused extreme volatility and disruptions in the capital and credit markets in recent years. Uncertainty or unfavorable global economic conditions could result in a variety of impacts to our business, including weakening demand for our products, and adversely impacting our ability to raise additional capital when needed on acceptable terms, if at all. A weak or declining economy has strained in the past and may in the future strain our manufacturers or suppliers, possibly resulting in supply disruption, or cause our customers to delay making payments for our services. Further, the Trump administration has proposed or enacted tariffs and substantial changes to trade policies, which could adversely affect our business. For example, the Trump administration has imposed tariffs on certain foreign products, including from Canada, Mexico and China, that in the past have resulted in and may result in future retaliatory tariffs on U.S. goods and products. Additionally, on September 25, 2025, the current U.S. administration announced a 100% tariff on brand-name or patented drugs unless pharmaceutical companies expand their manufacturing operations in the U.S., and may impose more restrictions on goods. Although the pharmaceutical tariff is currently on hold, this could have a material adverse effect on our supply chain and business prospects as well as the larger biopharmaceutical industry. While certain tariffs have subsequently been suspended, modified or temporarily reduced, we cannot predict the results of the U.S. government’s trade negotiations or the outcome of ongoing legal challenges to specific tariff policies. We cannot predict whether these policies will continue, or if new policies will be enacted, or the impact, if any, that any policy changes could have on our business. Any of the foregoing could harm our business and we cannot anticipate all of the ways in which the economic climate and financial market conditions could adversely affect our business.

There is also uncertainty surrounding potential changes to the healthcare regulatory environment in the United States, and it is not possible to predict how these changes may be implemented, and the ultimate effects of such changes on our business. In addition, the U.S. federal government and other governments may reduce funding for health care or other programs or make changes that adversely affect the number of persons eligible for certain programs, the services provided to enrollees in such programs and premiums we can charge. The levels of U.S. federal government spending are difficult to predict and are subject to significant risk. Considerable uncertainty exists regarding how future budget and program decisions will unfold, including the spending priorities of the new presidential administration and Congress, and what challenges budget reductions, if any, will present for our business and our industry generally. For example, on January 20, 2025, President Trump established by executive order the U.S. DOGE Service Temporary Organization ("DOGE") to reform federal government processes and reduce expenditures, and on February 5, 2025, the Centers for Medicare & Medicaid Services, or CMS, announced that it is collaborating with DOGE to determine where there may be opportunities for more effective and efficient use of resources. Further, there are reports that the administration is exploring and implementing policies which may put limits on, or freeze, credit card spending by government employees on behalf of government agencies. Additionally, the Trump administration took several Executive Actions, including the issuance of a number of Executive Orders, that imposed significant burdens on, or otherwise materially delayed, the FDA’s ability to engage in routine oversight activities, such as implementing statutes through rulemaking, issuance of guidance, and review and approval of marketing applications. It is difficult to predict whether additional orders will be implemented, or how these orders will be rescinded and replaced under the current or future administrations.

We must attract and retain highly skilled personnel and strategic partners, and we may be unable to effectively manage our growth with our limited resources.

We have limited human resources and our future success depends and will depend in part on our ability to attract, train, retain and motivate highly skilled executive level management, research and development, and sales personnel and to establish and maintain effective strategic alliances with key companies in our industry. Competition is intense for many of these types of

personnel from other companies, consulting firms and more established organizations, many of which have significantly larger operations and greater financial, marketing, human, and other resources. We may not be successful in attracting and retaining qualified personnel on a timely basis, on competitive terms or at all. If we are not successful in attracting and retaining these personnel, our business, prospects, financial condition and results of operations may be materially adversely affected.

We anticipate adding new employees and we will have to integrate such new employees into our operations.

Our officers and directors may not possess all of the skills or experience necessary to successfully implement our business plan. Further, we anticipate hiring new employees. Failure to fully integrate new employees into our operations could have a material adverse effect on our business, prospects, financial condition and results of operations.

We are exposed to the risk that our employees, independent contractors, consultants, commercial partners, suppliers and distributors may engage in fraudulent or illegal activity. Misconduct by these parties could include intentional, reckless or negligent conduct or disclosure of unauthorized activities to us that violates: (i) the rules and regulations of the FDA and other similar foreign regulatory bodies, including those laws requiring the reporting of true, complete and accurate information to such regulators; (ii) manufacturing standards; (iii) healthcare fraud and abuse laws in the United States and similar foreign fraudulent misconduct laws; or (iv) laws that require the true, complete and accurate reporting of financial information or data. These laws may impact, among other things, future sales, marketing and education programs. In particular, the promotion, sales and marketing of healthcare items and services, as well as certain business arrangements in the healthcare industry, are subject to extensive laws designed to prevent fraud, kickbacks, self-dealing and other abusive practices. These laws and regulations may restrict or prohibit a wide range of pricing, discounting, marketing and promotion, structuring and commissions, certain customer incentive programs and other business arrangements generally. Activities subject to these laws also involve the improper use of information obtained in the course of patient recruitment for clinical trials.

We have adopted a code of conduct, but it is not always possible to identify and deter misconduct by our employees and other third parties, and the precautions we take to detect and prevent these activities may not be effective 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 be in compliance with such laws or regulations. If any such actions are instituted against us and we are not successful in defending ourselves or asserting our rights, those actions could result in the imposition of significant fines or other sanctions, including the imposition of significant civil, criminal and administrative penalties, damages, monetary fines, disgorgement, imprisonment, additional integrity reporting and oversight obligations, possible exclusion from participation in Medicare, Medicaid and other federal healthcare programs, contractual damages, reputational harm, diminished profits and future earnings and curtailment of operations, any of which could adversely affect our ability to operate our business and our results of operations. Whether or not we are successful in defending against any such actions or investigations, we could incur substantial costs, including legal fees, and divert the attention of management in defending ourselves against any of these claims or investigations, which could harm our business, financial condition and results of operations.

We are limited in our ability to manufacture pharmaceutical products.

To be successful, our products and the products of our partners must be manufactured in commercial quantities in compliance with regulatory requirements and at a commercially acceptable cost. We have not commercialized any pharmaceutical products, nor have we demonstrated an ability to manufacture commercial quantities of our or our partners’ product candidates in accordance with regulatory requirements. If we are unable to produce suitable quantities of our or our partners’ products, or contract third parties to do so, in accordance with regulatory standards at a commercially acceptable cost, our ability or the ability of our partners to conduct clinical trials, obtain regulatory approvals and market such products may be adversely affected, which could adversely affect our competitive position and our chances of achieving profitability. There can be no assurance that such products can be manufactured by us or any other party at a cost or in quantities which are commercially viable.

We depend on our senior management and senior scientific staff, and their loss or unavailability could put us at a competitive disadvantage.

Our success depends largely on the skills, experience and reputation of certain key management and personnel, in particular our directors, executive officers and senior scientific staff. The loss or unavailability of any of these individuals for any significant period of time could have a material adverse effect on our business, prospects, financial condition and results of operations.

We do not have the ability to conduct all aspects of our preclinical studies or clinical trials ourselves. We depend on third parties, including contract research organizations (CROs), contract testing organizations (CTOs), contract manufacturers, and clinical investigators to perform research, preclinical studies, and clinical trials. The timing of our development programs will therefore be partially controlled by such third parties and may result in delays. As the sponsor of the INADs, INDs, and clinical protocols governing our trials, we remain responsible for ensuring compliance with applicable protocols and regulatory standards. We and our third-party contractors must comply with Good Laboratory Practice (GLP) requirements for preclinical studies and Good Clinical Practice (GCP) requirements for clinical trials, which are enforced by the FDA and comparable foreign regulatory authorities through periodic inspections. If we or our contractors fail to comply with these requirements, the data generated may be deemed unreliable, and regulators may require us to repeat studies or trials, which would delay the approval process.

Principal investigators for our clinical trials may serve as scientific advisors or consultants and receive compensation for such services. The FDA or comparable foreign regulatory authorities may conclude that such financial relationships create conflicts of interest that affect interpretation of trial data. This could result in regulators questioning data integrity, leading to delays or rejection of our marketing applications.

There is no guarantee that CROs, CTOs, clinical investigators, or other third parties will devote adequate time and resources to our development activities or perform as contractually required. Third-party performance may also be interrupted by public health emergencies. If any third party fails to meet deadlines, adhere to protocols, or meet regulatory requirements, our development timelines may be extended or suspended. If clinical trial sites terminate, we may lose follow-up information on enrolled subjects unless we can transfer them to another qualified site.

We intend to rely on third parties to produce commercial supplies of our product candidates.

We intend to rely on third-party manufacturers to supply us with sufficient quantities of our product candidates to be used, if approved, for commercialization. We do not yet have a commercial supply agreement for commercial quantities of drug substance or drug product. If we are not able to meet market demand for any approved product, it would negatively impact our ability to generate revenue, harm our reputation, and could have an adverse effect on our business and financial condition.

Further, our reliance on third-party manufacturers entails risks to which we would not be subject if we manufactured product candidates ourselves, including:

•

inability to meet our product specifications and quality requirements consistently;

•

delay or inability to procure or expand sufficient manufacturing capacity;

•

issues related to scale-up of manufacturing;

•

costs and validation of new equipment and facilities required for scale-up;

•

our third-party manufacturers may not be able to execute our manufacturing procedures and other logistical support requirements appropriately;

•

our third-party manufacturers may fail to comply with cGMP requirements and other inspections by the FDA or other comparable regulatory authorities;

•

our inability to negotiate manufacturing agreements with third parties under commercially reasonable terms, if at all;
