Up to 2,909,090 Shares of Common Stock

Up to 2,909,090 Pre-Funded Warrants to Purchase up to 2,909,090 Shares of Common Stock

Up to 2,909,090 Common Warrants to Purchase up to 2,909,090 Shares of Common Stock

Up to 2,909,090 shares of Common Stock Underlying the Pre-Funded Warrants

Up to 2,909,090 shares of Common Stock Underlying the Common Warrants

We are offering up to $8.0 million of shares of common stock together with common warrants to purchase up to 2,909,090 shares of common stock. Each share of our common stock, or pre-funded warrant in lieu thereof, is being sold together with a common warrant to purchase 1.0 share of our common stock. The shares of common stock and common warrants are immediately separable and will be issued separately in this offering, but must be purchased together in this offering.

We have assumed a public offering price of $2.75 per share, the last reported sale price of our common stock on The Nasdaq Capital Market on September 15, 2025. The common warrants will have an assumed initial exercise price of $2.75 per share (assuming an exercise price equal to the last reported sale price of our common stock on The Nasdaq Capital Market on September 15, 2025, which was $2.75 per share) and will have a five-year term. The actual public offering price will be determined between us, the Placement Agent (as defined below) and the investors in the offering, and may be at a discount to the current market price of our common stock. Therefore, the assumed public offering price used throughout this prospectus may not be indicative of the final offering price.

We are also offering pre-funded warrants to purchase up to 2,909,090 shares of common stock to those purchasers whose purchase of shares of common stock in this offering would result in the purchaser, together with its affiliates and certain related parties, beneficially owning more than 4.99% (or, at the election of the purchaser, 9.99%) of our outstanding common stock immediately following the consummation of this offering, in lieu of shares of common stock that would result in beneficial ownership in excess of 4.99% (or, at the election of the purchaser, 9.99%) of our outstanding common stock. Each pre-funded warrant is exercisable for one share of our common stock and has an exercise price of $0.001 per share. Each pre-funded warrant is being offered together with the common warrants. The pre-funded warrants and common warrants are immediately separable and will be issued separately in this offering, but must be purchased together in this offering. For each pre-funded warrant that we sell, the number of shares of common stock we are offering will be reduced on a one-for-one basis.

Pursuant to this prospectus, we are also offering the shares of common stock issuable upon the exercise of pre-funded warrants and common warrants offered hereby. These securities are being sold in this offering to certain purchasers under a securities purchase agreement dated       , 2025 between us and such purchasers.

We have engaged A.G.P./Alliance Global Partners to act as our sole placement agent (the “Placement Agent” or “A.G.P.”) in connection with this offering. We have engaged the Placement Agent in connection with the securities offered by this prospectus. The Placement Agent has no obligation to buy any of the securities from us or to arrange for the purchase or sale of any specific number or dollar amount of securities but has agreed to use its best efforts to sell the securities offered by this prospectus. We have agreed to pay the Placement Agent a fee based upon the aggregate gross proceeds raised in this offering as set forth in the table below.

The shares of our common stock, pre-funded warrants or common warrants being offered will be sold in a single closing. The shares issuable upon exercise of the pre-funded warrants or common warrants will be issued upon the exercise thereof. Because there is no minimum number of securities or minimum aggregate amount of proceeds for this offering to close, we may sell fewer than all of the securities offered hereby, and investors in this offering will not receive a refund in the event that we do not sell an amount of securities sufficient to pursue the business goals outlined in this prospectus. Because there is no escrow account and there is no minimum offering amount, investors could be in a position where they have invested in our company, but we are unable to fulfill our objectives due to a lack of interest in this offering. Also, any proceeds from the sale of securities offered by us will be available for our immediate use, despite uncertainty about whether we would be able to use such funds to effectively implement our business plan. The offering of the shares of our common stock, pre-funded warrants or common warrants will terminate no later than October 28, 2025; however, the shares of our common stock underlying the pre-funded warrants and the common warrants will be offered on a continuous basis pursuant to Rule 415 under the Securities Act of 1933, as amended (the “Securities Act”).

Our common stock is listed on The Nasdaq Capital Market under the symbol “SNGX.” The last reported sale price of our common stock on The Nasdaq Capital Market on September 15, 2025 was $2.75 per share. We do not intend to list the pre-funded warrants or the common warrants on any national securities exchange or other nationally recognized trading system.

An investment in our securities involves significant risks. You should carefully consider the risk factors beginning on page 8 of this prospectus before you make your decision to invest in our securities.

Neither the Securities and Exchange Commission nor any other regulatory body has approved or disapproved of these securities or passed upon the accuracy or adequacy of this prospectus. Any representation to the contrary is a criminal offense.

You should carefully read this entire prospectus before making an investment decision, including the information presented under the headings “Risk Factors” and “Cautionary Note Regarding Forward-Looking Statements and Industry Data and Market Information” in this prospectus and the historical financial statements and the notes thereto included elsewhere in this prospectus. You should pay special attention to the information contained under the caption titled “Risk Factors” in this prospectus, before deciding to buy our securities. In this prospectus, the terms “Soligenix,” “Soligenix, Inc.,” the “Company,” “we,” “our,” “ours” and “us” refer to Soligenix, Inc. and its subsidiaries.

Overview

We are a late-stage biopharmaceutical company focused on developing and commercializing products to treat rare diseases where there is an unmet medical need. We maintain two active business segments: Specialized BioTherapeutics and Public Health Solutions.

Our Specialized BioTherapeutics business segment is developing and moving toward potential commercialization of HyBryte™ (a proposed proprietary name of SGX301 or synthetic hypericin sodium), a novel photodynamic therapy, utilizing topical synthetic hypericin activated with safe visible light for the treatment of cutaneous T-cell lymphoma (“CTCL”). With successful completion of the first Phase 3 FLASH (Fluorescent Light Activated Synthetic Hypericin) study and agreement from the European Medicines Agency (“EMA”) on the key design components of a confirmatory Phase 3 placebo-controlled study evaluating the safety and efficacy of HyBryte™ in the treatment of CTCL patients with early-stage disease, we began patient enrollment during December 2024 for the second Phase 3 study called “FLASH2” (Fluorescent Light Activated Synthetic Hypericin 2). We anticipate top-line results in the second half of 2026. Upon successful completion of the Phase 3 FLASH2 study, regulatory approval will be sought to support potential commercialization worldwide.

Development programs in this business segment also include expansion of synthetic hypericin (SGX302) into psoriasis, and our first-in-class Innate Defense Regulator technology, dusquetide, for the treatment of inflammatory diseases, including oral mucositis in head and neck cancer (SGX942) and aphthous ulcers in Behçet’s Disease (SGX945).

Our Public Health Solutions business segment includes development programs for RiVax^®, our ricin toxin vaccine candidate and SGX943, our therapeutic candidate for antibiotic resistant and emerging infectious disease and our vaccine programs targeting filoviruses (such as Marburg and Ebola) and CiVax™, our vaccine candidate for the prevention of COVID 19 (caused by SARS-CoV 2). The development of our vaccine programs incorporates the use of our proprietary heat stabilization platform technology, known as ThermoVax^®. To date, this business segment has been supported with government grant and contract funding from the National Institute of Allergy and Infectious Diseases (“NIAID”), the Biomedical Advanced Research and Development Authority, and the Defense Threat Reduction Agency.

Recent Developments

On August 15, 2025, we received notice (the “Notice”) from The Nasdaq Stock Market LLC (“Nasdaq”) advising us that we were not in compliance with the minimum stockholders’ equity requirement for continued listing on The Nasdaq Capital Market. Nasdaq Listing Rule 5550(b)(1) requires companies listed on The Nasdaq Capital Market to maintain stockholders’ equity of at least $2,500,000 (the “Stockholders’ Equity Requirement”). In our Quarterly Report on Form 10-Q for the quarter ended June 30, 2025, we reported stockholders’ equity of $1,828,951, which is below the Stockholders’ Equity Requirement for continued listing. This amount did not reflect common stock sales on July 1, 2025, which generated total gross proceeds of approximately $1,439,300. Additionally, as of the date of the Notice, we did not meet either of the alternative Nasdaq continued listing standards under the Nasdaq Listing Rules, market value of listed securities of at least $35 million, or net income of $500,000 from continuing operations in the most recently completed fiscal year, or in two of the three most recently completed fiscal years.

The Notice had no immediate effect on the listing of our common stock and our common stock continues to trade on The Nasdaq Capital Market under the symbol “SNGX,” subject to our compliance with the other continued listing requirements.

Pursuant to the Notice, Nasdaq has given us 45 calendar days from the date of the Notice, or until September 29, 2025, to submit to Nasdaq a plan to regain compliance. If our plan is accepted, Nasdaq may grant an extension of up to 180 calendar days from the date of the Notice to evidence compliance.

In order to regain compliance with the Shareholders’ Equity Requirement, we are offering the securities in this offering. We estimate (based upon assumptions we believe are reasonable) that we will have more than the required $2.5 million in shareholders’ equity as of the closing date provided we receive net proceeds of at least $3.4 million in this offering. There can be no assurance that we will be able to regain compliance with the Shareholders’ Equity Requirement, or that our common stock will remain listed on The Nasdaq Capital Market. See “Risks Related to this Offering — If we fail to meet Nasdaq’s listing requirements, we could be removed from The Nasdaq Capital Market, which would limit the ability of broker-dealers to sell our securities and the ability of shareholders to sell their securities in the secondary market and negatively impact our ability to raise capital.” on page 34 of this prospectus.

RISK FACTORS

Investing in our common stock, pre-funded warrants and common warrants involves a high degree of risk. Before investing in our common stock, pre-funded warrants and common warrants, you should consider carefully the risks and uncertainties discussed below. You should carefully consider each of the following risks, together with all other information set forth in this prospectus, including our consolidated financial statements and the related notes, before deciding to buy our common stock, pre-funded warrants and common warrants. If any of the following risks actually occurs, our business could be harmed. In that case, the trading price of our common stock could decline, and you may lose all or part of your investment.

This prospectus also contains forward-looking statements that involve risks and uncertainties. Our actual results could differ materially from those anticipated in these forward-looking statements as a result of certain factors, including the risks faced by us described below and elsewhere in this prospectus. See “Cautionary Note Regarding Forward-Looking Statements and Industry Data and Market Information” for information relating to these forward-looking statements.

Risks Related to our Business

We have incurred significant losses since inception and expect to continue to incur losses for the foreseeable future, which together with our negative cash flows and auditor’s going concern opinion raise substantial doubt about our ability to continue as a going concern without obtaining additional capital.

We have incurred significant losses since inception and expect to continue incurring operating losses for the foreseeable future. As of June 30, 2025, we had an accumulated deficit of approximately $246.6 million, cash and cash equivalents of approximately $5.1 million, and current liabilities of approximately $3.6 million. We have not generated any significant revenues from sales or licensing of our product candidates, which are in preclinical or clinical development stages. From inception through June 30, 2025, we have spent approximately $128 million developing our current product candidates, and we currently anticipate spending approximately $4.8 million over the next 12 months to support further development activities, of which only a small portion is expected to be reimbursed through existing government grants.

We rely heavily on government funding, including grants and contracts from agencies such as the NIH and NIAID, to support our operations. These grants and contracts have contributed meaningful funding historically. However, such funding is subject to uncertainty, periodic renewal, and potential termination at the discretion of the funding agencies. As of June 30, 2025, we did not have any awarded grant funding available, and we have no control over the level or continuity of government resources that may be allocated to our programs in the future. Failure to obtain government support in the future could materially and adversely impact our biodefense programs and overall financial condition.

Unless and until we are able to generate revenues from product sales or licensing activities, we will need to raise additional capital to fund our research and development programs, meet future clinical trial obligations, and support ongoing operations. There can be no assurance that such funding will be available on acceptable terms, or at all. If additional funds are raised through equity offerings, existing stockholders may experience dilution, and newly issued securities could have rights senior to those of our common stock. If we issue debt, we could face operational restrictions. If we are unable to secure adequate funding, we may be required to delay, scale back, or discontinue one or more of our development programs or operational initiatives.

Our recurring operating losses, negative cash flows, and accumulated shareholders’ deficit raise substantial doubt about our ability to continue as a going concern. We have concluded that substantial doubt exists regarding our ability to continue as a going concern for the 12 months following the date of issuance of the financial statements for the fiscal quarter ended June 30, 2025 that are included in this prospectus. As of such date, we believed we had sufficient resources to continue operating only into the fourth quarter of 2025. We do not have sufficient cash as of September 15, 2025 to support operations for the full 12-month period following such issuance.

To address these risks and alleviate the conditions that raise substantial doubt about our ability to continue as a going concern, we are pursuing various strategies, including:

None of these alternatives are currently committed, and we cannot provide assurance that we will succeed in obtaining sufficient funding or entering into strategic arrangements. If these efforts are unsuccessful or delayed, we may not have the liquidity necessary to sustain operations beyond the fourth quarter of 2025.

Further, the report of our independent registered accounting firm on our audited financial statements for the year ended December 31, 2024, includes an explanatory paragraph expressing substantial doubt about our ability to continue as a going concern. If we are unable to resolve our liquidity issues or secure sufficient funding, we will likely need to significantly reduce our operations, limit or cease product development efforts, and our business, financial condition, results of operations, and prospects would be materially and adversely affected. Additionally, ongoing market volatility and geopolitical instability may reduce access to capital, and the perception of going concern uncertainty may hinder our ability to establish or maintain business relationships.

If we are unable to develop our product candidates, our ability to generate revenues and viability as a company will be significantly impaired.

In order to generate revenues and profits, our organization must, along with corporate partners and collaborators, positively research, develop and commercialize our technologies or product candidates. Our current product candidates are in various stages of clinical and pre-clinical development and will require significant further funding, research, development, pre-clinical and/or clinical testing, regulatory approval and commercialization, and are subject to the risks of failure inherent in the development of products based on innovative or novel technologies. Specifically, each of the following is possible with respect to any of our product candidates:

If any of the risks set forth above occur, or if we are unable to obtain the necessary regulatory approvals as discussed below, we may be unable to develop our technologies and product candidates and our business will be seriously harmed. Furthermore, for reasons including those set forth below, we may be unable to commercialize or receive royalties from the sale of any other technology we develop, even if it is shown to be effective, if:

We expect a number of factors to cause our operating results to fluctuate on a quarterly and annual basis, which may make it difficult to predict our future performance.

We are a late-stage biopharmaceutical company. Our operations to date have been primarily limited to developing our technology and undertaking pre-clinical studies and clinical trials of our product candidates in our two active business segments, Specialized BioTherapeutics and Public Health Solutions. We have not yet obtained regulatory approvals for any of our product candidates. Consequently, any predictions made about our future success or viability may not be as accurate as they could be if we had commercialized products. Our financial condition has varied significantly in the past and will continue to fluctuate from quarter-to-quarter or year-to-year due to a variety of factors, many of which are beyond our control. Factors relating to our business that may contribute to these fluctuations include other factors described elsewhere in this prospectus and also include:

Accordingly, the results of any quarterly or annual periods should not be relied upon as indications of future operating performance.

We have no approved products on the market and therefore do not expect to generate any revenues from product sales in the foreseeable future, if at all.

To date, we have no approved product on the market and have not generated any significant product revenues. We have funded our operations primarily from sales of our securities and from government contracts and grants. We have not received, and do not expect to receive for at least the next several years, if at all, any revenues from the commercialization of our product candidates. To obtain revenues from sales of our product candidates, we must succeed, either alone or with third parties, in developing, obtaining regulatory approval for, manufacturing and marketing drugs with commercial potential or successfully obtain government procurement or stockpiling agreements. We may never succeed in these activities, and we may not generate sufficient revenues to continue our business operations or achieve profitability.

Our business is subject to extensive governmental regulation, which can be costly, time consuming and subjects us to unanticipated delays.

Our business is subject to very stringent federal, foreign, state and local government laws and regulations, including the Federal Food, Drug and Cosmetic Act, the Environmental Protection Act, the Occupational Safety and Health Act, and state and local counterparts to these acts. These laws and regulations may be amended, additional laws and regulations may be enacted, and the policies of the FDA and other regulatory agencies may change.

The regulatory process applicable to our products requires pre-clinical and clinical testing of any product to establish its safety and efficacy. This testing can take many years, is uncertain as to outcome, and requires the expenditure of substantial capital and other resources. We estimate that the clinical trials of our product candidates that we have planned will take at least several years to complete. Furthermore, failure can occur at any stage of the trials, and we could encounter problems that cause us to abandon or repeat clinical trials. Favorable results in early studies or trials, if any, may not be repeated in later studies or trials. Even if our clinical trials are initiated and completed as planned, we cannot be certain that the results will support our product candidate claims. Success in preclinical testing, Phase 1 and Phase 2 clinical trials does not ensure that later Phase 2 or Phase 3 clinical trials will be successful. In addition, we, the FDA or other regulatory authorities may suspend clinical trials at any time if it appears that we are exposing participants to unacceptable health risks or the FDA or other regulatory authorities find deficiencies in our submissions or conduct of our trials.

We may not be able to obtain, or we may experience difficulties and delays in obtaining, necessary domestic and foreign governmental clearances and approvals to market a product (for example, the FDA may not recognize fast track designation upon an NDA submission, resulting in no priority review and subjecting us to longer potential review times than originally anticipated). Also, even if regulatory approval of a product is granted, that approval may entail limitations on the indicated uses for which the product may be marketed.

Following any regulatory approval, a marketed product and its manufacturer are subject to continual regulatory review. Later discovery of problems with a product or manufacturer may result in restrictions on such product or manufacturer. These restrictions may include product recalls and suspension or withdrawal of the marketing approval for the product. Furthermore, the advertising, promotion and export, among other things, of a product are subject to extensive regulation by governmental authorities in the U.S. and other countries. If we fail to comply with applicable regulatory requirements, we may be subject to fines, suspension or withdrawal of regulatory approvals, product recalls, seizure of products, operating restrictions and/or criminal prosecution.

Our biodefense programs depend heavily on uncertain government funding and face unique regulatory, operational, and market challenges.

Our biodefense product development efforts are highly dependent on financial support from U.S. government agencies, which represent both the primary source of funding and the principal anticipated purchasers of these products. This reliance exposes us to significant risks, as government funding is inherently uncertain and subject to annual budget appropriations, administrative decisions, changes in biodefense priorities, and political developments. We have no control over the level of resources government agencies may

commit to our programs, which are subject to periodic renewal and may be terminated at any time for convenience. If U.S. government agencies decide not to exercise future funding options under existing contracts or grants, fail to perform their responsibilities, or terminate funding altogether, our biodefense programs and financial results could be materially and adversely affected.

Additionally, we are required to comply with Federal Acquisition Regulations in the performance of our contracts. Failure to meet these obligations may result in corrective actions, loss of funding, or the obligation to return government property or deliver incomplete work. Even when funding is awarded, our continued receipt of support is conditioned on adherence to the terms of the applicable grant or contract, which may be complex and subject to interpretation.

Beyond funding concerns, the development and approval of biodefense products present unique regulatory and logistical challenges. While the FDA has instituted the Animal Rule to permit product approval based on animal efficacy studies when human trials are not feasible or ethical, demonstrating sufficient animal-to-human correlation remains scientifically complex and uncertain. We must also show that our products are safe in humans, and in some cases, conduct trials in specific at-risk populations, such as children, the elderly, or pregnant women. Approval may still be contingent upon additional post-marketing studies, and use may be restricted to limited populations or emergency stockpile deployment. Moreover, other countries have not established equivalent regulatory frameworks for Animal Rule-based submissions, which limits our ability to pursue foreign approvals using the same data.

The development of effective animal models for certain bioterrorism agents, such as ricin, is time- consuming and expensive, and few specialized facilities exist globally to conduct the necessary studies. We face competition from other biodefense companies for access to these limited resources, which may delay or impede testing and qualification efforts.

Finally, the biodefense market itself remains largely unproven. We do not expect significant commercial demand outside of government procurement, and shifts in government policy or strategic priorities could reduce or eliminate potential opportunities. If government support diminishes or is withdrawn, we may be unable to progress our biodefense initiatives, which could have a material adverse impact on our business, operations, and financial condition.

We rely on third parties for the supply and manufacturing of our product candidates, and any delays, failures, or quality issues could adversely affect our development and commercialization efforts.

We depend entirely on third-party suppliers for our drug substance raw materials and for the performance of critical manufacturing-related services. We do not have, nor do we anticipate establishing, internal manufacturing capabilities. These third parties must produce materials that meet stringent quality, content, and stability requirements necessary for our clinical trials and, if approved, for commercial distribution.

The successful development and commercialization of our product candidates require uninterrupted access to sufficient quantities of drug substance and drug product that meet applicable regulatory standards. However, our suppliers and service providers may fail to:

If any of these events occur, we may face delays in clinical trials, regulatory submissions, or product launches. Furthermore, should our relationships with key manufacturers or service providers be disrupted, we may not be able to secure suitable replacements in a timely or cost-effective manner, if at all. Even if we locate alternative providers, we may not be able to negotiate favorable terms, and qualifying new facilities with the FDA or foreign regulatory agencies can be time-consuming and costly.

Manufacturing our product candidates is a highly exacting process, and even minor deviations in production can result in failed batches, regulatory noncompliance, or product recalls. Regulatory authorities routinely inspect manufacturing facilities for cGMP compliance. Any failure by our suppliers to maintain these standards could result in clinical hold orders, delays in product

development or commercialization, or denial or withdrawal of product approvals. These risks could materially and adversely affect our business, financial condition, and results of operations.

We rely on third parties for preclinical and clinical development, regulatory support, and strategic execution, and their performance or our resource allocation decisions could adversely affect our product development efforts and commercial potential.

We rely on academic institutions, hospitals, clinics, contract research organizations, and other third-party collaborators to conduct preclinical studies and clinical trials of our product candidates, and in some cases, to maintain related regulatory files. Because we do not conduct these activities internally, we have limited control over the execution, timing, and costs of these studies, and less influence over patient enrollment and data quality than if we managed the trials ourselves.

If we are unable to maintain or secure agreements with these third parties on commercially reasonable terms, or if any such agreements are terminated, we may face delays in trial initiation or completion. Moreover, there is no assurance that our collaborators will allocate sufficient resources to our programs, perform in accordance with regulatory requirements, or adhere to protocols and deadlines. If they fail to transfer regulatory data to us on a timely basis, perform inadequately, or act in a way that compromises the integrity of clinical results, our ability to obtain regulatory approval or to commercialize our product candidates could be materially impaired.

Additionally, our limited financial and human resources require us to make strategic decisions regarding which programs to prioritize. As a result, we may delay or forego pursuing product candidates or indications that could ultimately prove to have greater commercial value or development success. If we misjudge the market opportunity or technical feasibility of a candidate, we may prematurely enter into suboptimal strategic alliances or license agreements, or conversely, fail to capitalize on valuable opportunities that would have been more advantageous to develop internally.

Collectively, these risks related to third-party reliance and internal resource allocation could significantly delay development timelines, reduce the likelihood of regulatory approval, and limit our ability to bring commercially viable products to market.

Even if approved, our products will be subject to extensive post-approval regulation.

Once a product is approved, numerous post-approval requirements apply. Among other things, the holder of an approved NDA is subject to periodic and other FDA monitoring and reporting obligations, including obligations to monitor and report adverse events and instances of the failure of a product to meet the specifications in the NDA. Application holders must submit new or supplemental applications and obtain FDA approval for certain changes to the approved product, product labeling, or manufacturing process. Application holders must also submit advertising and other promotional material to the FDA and report on ongoing clinical trials.

Depending on the circumstances, failure to meet these post-approval requirements can result in criminal prosecution, fines, injunctions, recall or seizure of products, total or partial suspension of production, denial or withdrawal of pre-marketing product approvals, or refusal to allow us to enter into supply contracts, including government contracts. In addition, even if we comply with FDA and other requirements, new information regarding the safety or effectiveness of a product could lead the FDA to modify or withdraw product approval.

Even if our product candidates are approved, they may not achieve market acceptance or commercial viability due to changing healthcare practices, payer limitations, and reimbursement challenges.

Even if we obtain regulatory approval to market one or more of our product candidates, we may be unable to successfully commercialize them due to lack of market acceptance by healthcare providers, patients, and third-party payors. Our future revenue and profitability depend heavily on the successful commercialization of our current product candidates, which, if approved, are expected to generate substantially all of our product revenue for the foreseeable future.

The degree of market acceptance will depend on numerous factors, including:

Failure to achieve meaningful market acceptance would significantly limit our ability to generate product revenue, and we may not be able to recover our investment in the development of these product candidates.

In addition, changes in healthcare delivery and reimbursement practices, both in the U.S. and internationally, could further hinder the commercial success of our products. U.S. federal and state governments, as well as private insurers, are continuing to pursue cost-containment initiatives, such as bundling payments, implementing price controls, and imposing tighter restrictions on reimbursement eligibility. The availability of appropriate billing codes and national or local coverage determinations will be critical to securing reimbursement. If our products are not covered under current Medicare or Medicaid policies — or if coverage decisions are deferred to local contractors — we may face significant delays or reductions in uptake.

Outside the U.S., many countries require government approval of drug pricing before commercial launch, and the rules governing pricing and reimbursement vary significantly. Any inability to secure favorable pricing and reimbursement in global markets would further restrict the commercial viability of our products.

Ongoing legislative proposals at both federal and state levels in the U.S. aim to impose new pricing controls or reform reimbursement models, adding additional uncertainty to the reimbursement environment. These dynamics could make it difficult for us to profitably commercialize our products even if they are successfully developed and approved, and could ultimately have a material adverse effect on our business, financial condition, and operating results.

We do not have extensive sales and marketing experience and our lack of experience may restrict our success in commercializing some of our product candidates.

We do not have extensive experience in marketing or selling pharmaceutical products whether in the U.S. or internationally. To obtain the expertise necessary to successfully market and sell any of our products, the development of our own commercial infrastructure and/or collaborative commercial arrangements and partnerships will be required. Our ability to make that investment and also execute our current operating plan is dependent on numerous factors, including, the performance of third-party collaborators with whom we may contract.

Our product candidates may cause serious adverse events or undesirable side effects which may delay or prevent marketing approval, or, if approval is received, require them to be taken off the market, require them to include safety warnings or otherwise limit their sales.

Serious adverse events or undesirable side effects from any of our product candidates could arise either during clinical development or, if approved, after the approved product has been marketed. The results of future clinical trials may show that our product candidates cause serious adverse events or undesirable side effects, which could interrupt, delay or halt clinical trials, resulting in delay of, or failure to obtain, marketing approval from the FDA and other regulatory authorities.

If any of our product candidates cause serious adverse events or undesirable side effects:

Any of these events could prevent us from achieving or maintaining market acceptance of the affected product or could substantially increase commercialization costs and expenses, which in turn could delay or prevent us from generating significant revenues from the sale of our products.

If we fail to obtain or maintain orphan drug designation or exclusivity for our product candidates, our competitive position and revenue potential could be adversely affected.

Certain of our product candidates, such as HyBryte™, have received orphan drug designation in the U.S. and/or Europe, and we may seek additional orphan designations for other product candidates in the future. Orphan drug designation provides important financial incentives and regulatory benefits, including tax credits, fee waivers, and, if granted marketing approval, a period of market exclusivity — seven years in the U.S. and ten years in the European Union. However, we or our collaborators may not be able to obtain or maintain orphan drug designation or exclusivity for any current or future product candidates.

In the U.S., the Orphan Drug Act defines a rare disease or condition as one affecting fewer than 200,000 individuals annually, or where there is no reasonable expectation that the cost of development will be recovered through U.S. sales. In the EU, a condition must affect no more than five in 10,000 individuals, or the product must demonstrate significant benefit over existing treatments. Even if we meet these criteria and receive orphan drug designation, exclusivity is only granted upon the first marketing approval for the designated indication.

Even if orphan drug exclusivity is obtained, it may not effectively protect our products from competition. Regulatory authorities, including the FDA and EMA, may approve different drugs for the same indication or even drugs with the same active moiety if they determine the competing product is clinically superior, meaning it is safer, more effective, or makes a major contribution to patient care. Additionally, exclusivity may be lost if the sponsor is unable to assure sufficient product supply or if the designation is found to be materially defective. In Europe, exclusivity can also be reduced to six years if the drug is deemed sufficiently profitable or if it no longer meets the criteria for orphan designation.

Furthermore, orphan drug protections exist within a complex and evolving regulatory framework. FDA policy changes, new legislation, judicial interpretation, or administrative actions may alter the standards for obtaining or retaining orphan drug status. We cannot predict how future regulatory or policy developments will affect the application or interpretation of orphan drug laws, either in the U.S. or abroad.

Lastly, in the EU, obtaining orphan designation requires demonstrating that there is no satisfactory method of diagnosis, prevention, or treatment currently authorized in the EU, or that the proposed product offers substantial benefit over existing methods. We may be unable to meet these standards for our product candidates.

If we fail to obtain or maintain orphan drug designation or exclusivity for our product candidates, we could lose important commercial and regulatory advantages. Competitors may be able to market similar or superior products for the same conditions, which could reduce our potential market share, impair our competitive position, and adversely affect our ability to achieve or sustain profitability.

We may not be able to retain rights licensed to us by third parties to commercialize key products or to develop the third-party relationships we need to develop, manufacture and market our products.

We currently rely on license agreements from New York University, Yeda Research and Development Company Ltd., the University of Texas Southwestern Medical Center, the University of British Columbia, and George B. McDonald, MD as well as sublicense agreement from VitriVax for the rights to commercialize key product candidates. We may not be able to retain the rights granted under these agreements or negotiate additional agreements on reasonable terms, if at all. Our existing license agreements impose, and we expect that future license agreements will impose, various diligence, milestone payment, royalty, and other obligations on us. If we fail to comply with our obligations under these agreements, or we are subject to a bankruptcy, we may be required to make certain payments to the licensor, we may lose the exclusivity of our license, or the licensor may have the right to terminate the license, in which event we would not be able to develop or market products covered by the license.

Additionally, the milestone and other payments associated with these licenses will make it less profitable for us to develop our drug candidates. See “Business — Patents and Other Proprietary Rights” for a description of our license agreements.

Licensing of intellectual property is of critical importance to our business and involves complex legal, business, and scientific issues. Disputes may arise regarding intellectual property subject to a licensing agreement, including but not limited to:

If disputes over intellectual property and other rights that we have licensed prevent or impair our ability to maintain our current licensing arrangements on acceptable terms, we may be unable to successfully develop and commercialize the affected product candidates.

Additionally, the research resulting in certain of our licensed patent rights and technology was funded by the U.S. government. As a result, the government may have certain rights, or march-in rights, to such patent rights and technology. When new technologies are developed with government funding, the government generally obtains certain rights in any resulting patents, including a non-exclusive license authorizing the government to use the invention for non-commercial purposes. The government can exercise its march-in rights if it determines that action is necessary because we fail to achieve practical application of the government-funded technology, because action is necessary to alleviate health or safety needs, to meet requirements of federal regulations or to give preference to U.S. industry. In addition, our rights in such inventions may be subject to certain requirements to manufacture products embodying such inventions in the U.S. Any exercise by the government of such rights could harm our competitive position, business, financial condition, results of operations and prospects.

Furthermore, we currently have very limited product development capabilities and no manufacturing, marketing or sales capabilities. For us to research, develop and test our product candidates, we need to contract or partner with outside researchers, in most cases with or through those parties that did the original research and from whom we have licensed the technologies. If products are successfully developed and approved for commercialization, then we will need to enter into additional collaboration and other agreements with third parties to manufacture and market our products. We may not be able to induce the third parties to enter into these agreements, and, even if we are able to do so, the terms of these agreements may not be favorable to us. Our inability to enter into these agreements could delay or preclude the development, manufacture and/or marketing of some of our product candidates or could significantly increase the costs of doing so. In the future, we may grant to our development partners rights to license and commercialize pharmaceutical and related products developed under the agreements with them, and these rights may limit our flexibility in considering alternatives for the commercialization of these products. Furthermore, third-party manufacturers or suppliers may not be able to meet our needs with respect to timing, quantity and quality for the products.

Additionally, if we do not enter into relationships with additional third parties for the marketing of our products, if and when they are approved and ready for commercialization, we would have to build our own sales force or enter into commercialization agreements with other companies. Development of an effective sales force in any part of the world would require significant financial resources, time and expertise. We may not be able to obtain the financing necessary to establish a sales force in a timely or cost effective manner, if at all, and any sales force we are able to establish may not be capable of generating demand for our product candidates, if they are approved.

We may suffer product and other liability claims; we maintain only limited product liability insurance, which may not be sufficient.

The clinical testing, manufacture and sale of our products involves an inherent risk that human subjects in clinical testing or consumers of our products may suffer serious bodily injury or death due to side effects, allergic reactions or other unintended negative reactions to our products. As a result, product and other liability claims may be brought against us. We currently have clinical trial and product liability insurance with aggregate limits of liability of $10 million, which may not be sufficient to cover our potential liabilities. Because liability insurance is expensive and difficult to obtain, we may not be able to maintain existing insurance or obtain additional liability insurance on acceptable terms or with adequate coverage against potential liabilities. Furthermore, if any claims are brought against us, even if we are fully covered by insurance, we may suffer harm such as adverse publicity.

We may use hazardous chemicals in our business. Potential claims relating to improper handling, storage or disposal of these chemicals could affect us and be time consuming and costly.

Our research and development processes and/or those of our third-party contractors involve the controlled use of hazardous materials and chemicals. These hazardous chemicals are reagents and solvents typically found in a chemistry laboratory. Our operations also may produce hazardous waste products. Federal, state and local laws and regulations govern the use, manufacture, storage, handling and disposal of hazardous materials. While we attempt to comply with all environmental laws and regulations, including those relating to the outsourcing of the disposal of all hazardous chemicals and waste products, we cannot eliminate the risk of contamination from or discharge of hazardous materials and any resultant injury. In the event of such an accident, we could be held liable for any resulting damages and any liability could materially adversely affect our business, financial condition and results of operations.

Compliance with environmental laws and regulations may be expensive. Current or future environmental regulations may impair our research, development or production efforts. We might have to pay civil damages in the event of an improper or unauthorized release of, or exposure of individuals to, hazardous materials. We are not insured against these environmental risks. We may agree to indemnify our collaborators in some circumstances against damages and other liabilities arising out of development activities or products produced in connection with these collaborations.

In addition, the federal, state and local laws and regulations governing the use, manufacture, storage, handling and disposal of hazardous or radioactive materials and waste products may require us to incur substantial compliance costs that could materially adversely affect our business, financial condition and results of operations.

We may not be able to compete with our larger and better financed competitors in the biotechnology industry.

The biotechnology industry is intensely competitive, subject to rapid change and sensitive to new product introductions or enhancements. Most of our existing competitors have greater financial resources, larger technical staffs, and larger research budgets

than we have, as well as greater experience in developing products and conducting clinical trials. Our competition is particularly intense in the gastroenterology and transplant areas and is also intense in the therapeutic area of inflammatory bowel diseases. We face intense competition in the biodefense area from various public and private companies and universities as well as governmental agencies, such as the U.S. Army, which may have their own proprietary technologies that may directly compete with our technologies. In addition, there may be other companies that are currently developing competitive technologies and products or that may in the future develop technologies and products that are comparable or superior to our technologies and products. We may not be able to compete with our existing and future competitors, which could lead to the failure of our business.

Additionally, if a competitor receives FDA approval before we do for a drug that is similar to one of our product candidates, FDA approval for our product candidate may be precluded or delayed due to periods of non-patent exclusivity and/or the listing with the FDA by the competitor of patents covering its newly-approved drug product. Periods of non-patent exclusivity for new versions of existing drugs such as our current product candidates can extend up to three and one-half years. See “Business — The Drug Approval Process.”

These competitive factors could require us to conduct substantial new research and development activities to establish new product targets, which would be costly and time consuming. These activities would adversely affect our ability to commercialize products and achieve revenue and profits.

Competition and technological change may make our product candidates and technologies less attractive or obsolete.

We compete with established pharmaceutical and biotechnology companies that are pursuing other forms of treatment for the same indications we are pursuing and that have greater financial and other resources. Other companies may succeed in developing products earlier than us, obtaining FDA approval for products more rapidly, or developing products that are more effective than our product candidates. Research and development by others may render our technology or product candidates obsolete or noncompetitive, or result in treatments or cures superior to any therapy we develop. We face competition from companies that internally develop competing technology or acquire competing technology from universities and other research institutions. As these companies develop their technologies, they may develop competitive positions that may prevent, make futile, or limit our product commercialization efforts, which would result in a decrease in the revenue we would be able to derive from the sale of any products.

There can be no assurance that any of our product candidates will be accepted by the marketplace as readily as these or other competing treatments. Furthermore, if our competitors’ products are approved before ours, it could be more difficult for us to obtain approval from the FDA. Even if our products are successfully developed and approved for use by all governing regulatory bodies, there can be no assurance that physicians and patients will accept our product(s) as a treatment of choice.

Furthermore, the pharmaceutical research industry is diverse, complex, and rapidly changing. By its nature, the business risks associated therewith are numerous and significant. The effects of competition, intellectual property disputes, market acceptance, and FDA regulations preclude us from forecasting revenues or income with certainty or even confidence.

Our business could be harmed if we fail to retain our current personnel or if they are unable to effectively run our business.

We currently have 15 employees and we depend upon these employees, in particular Dr. Christopher Schaber, our President and Chief Executive Officer, to manage the day-to-day activities of our business. Because we have such limited personnel, the loss of any of them or our inability to attract and retain other qualified employees in a timely manner would likely have a negative impact on our operations. We may be unable to effectively manage and operate our business, and our business may suffer, if we lose the services of our employees.

Instability and volatility in the financial markets could have a negative impact on our business, financial condition, results of operations, and cash flows.

During recent years, there has been substantial volatility in financial markets due at least in part to the uncertainty regarding the global economic environment. In addition, there has been substantial uncertainty in the capital markets and access to additional financing is uncertain. Moreover, customer spending habits may be adversely affected by current and future economic conditions. These conditions could have an adverse effect on our industry and business, including our financial condition, results of operations, and cash flows.

To the extent that we do not generate sufficient cash from operations, we may need to issue stock or incur indebtedness to finance our plans for growth. Recent turmoil in the credit markets and the potential impact on the liquidity of major financial institutions may have an adverse effect on our ability to fund our business strategy through borrowings, under either existing or newly created instruments in the public or private markets on terms we believe to be reasonable, if at all.

Changes in U.S. and international trade policies may adversely impact our business and operating results.

The U.S. government has recently made statements and taken certain actions that may lead to potential changes to U.S. and international trade policies, including imposing several rounds of tariffs and export control restrictions affecting certain products manufactured in other countries. It is unknown whether and to what extent new tariffs, export controls, or other new laws or regulations will be adopted, or the effect that any such actions would have on us or our business or industry.

Any unfavorable government policies on international trade, such as export controls, capital controls or tariffs, may increase the cost of manufacturing our product candidates, affect the demand for our drug products (if and once approved), the competitive position of our product candidates, and import or export of raw materials and finished product candidate used in our and our collaborators’ preclinical studies and clinical trials. If any new tariffs, export controls, legislation and/or regulations are implemented, or if existing trade agreements are renegotiated, such changes could have an adverse effect on our business, financial condition and results of operations.

Adverse developments affecting financial institutions such as actual events or concerns involving liquidity, defaults or non-performance, could adversely affect our operations and liquidity.

Actual events involving limited liquidity, defaults, non-performance or other adverse developments that affect financial institutions, or concerns or rumors about any events of these kinds, have in the past and may in the future lead to market-wide liquidity problems. For example, on March 10, 2023, Silicon Valley Bank (“SVB”) was closed by the California Department of Financial Protection and Innovation, which appointed the Federal Deposit Insurance Corporation (the “FDIC”) as receiver. Despite subsequent actions taken by the U.S. Department of the Treasury, the U.S. Federal Reserve and the FDIC to ensure that all depositors of SVB had access to all of their cash deposits following the closure of SVB, uncertainty and liquidity concerns in the broader financial services industry remain.

We maintain cash balances at a third-party financial institution in excess of the FDIC insurance limit. Our access to our cash and cash equivalents in amounts adequate to finance our operations could be significantly impaired to the extent the financial institution with which we maintain cash balances faces liquidity constraints or failures. Any material decline in our ability to access our cash and cash equivalents could adversely impact our ability to meet our operating expenses, result in breaches of our contractual obligations or result in significant disruptions to our business, any of which could have material adverse impacts on our operations and liquidity. There is no guarantee that the U.S. Department of Treasury, the U.S. Federal Reserve and the FDIC will provide access to uninsured funds in the future in the event of the closure of other banks or financial institutions in a timely fashion or at all.

We may not be able to utilize all of our net operating loss carryforwards.

The State of New Jersey’s Technology Business Tax Certificate Program allows certain high technology and biotechnology companies to sell unused net operating loss (“NOL”) carryforwards to other New Jersey-based corporate taxpayers. We sold 2023, 2022 and 2021 New Jersey NOL carryforwards, resulting in the recognition of $409,114 and $1,767,803 of income tax benefit, net of transaction costs during the years ended December 31, 2024 and 2023, respectively. We have not yet sold our 2024 New Jersey NOL carryforwards but may do so in the future. If there is an unfavorable change in the State of New Jersey’s Technology Business Tax Certificate Program (whether as a result of a change in law, policy or otherwise) that terminates the program or eliminates or reduces our ability to use or sell our NOL carryforwards or if we are unable to find a suitable buyer to utilize our New Jersey NOL carryforwards to the extent the NOLs expire before we are able to utilize them against our taxable income, our cash taxes may increase which may have an adverse effect on our financial condition.

Global pathogens that could have an impact on financial markets, materials sourcing, patients, governments and population (e.g. COVID-19).

Global pathogens (e.g., SARS-CoV-2, the pathogen responsible for COVID-19) could cause an impact on financial markets and therefore repercussions to our operating business, including but not limited to, the sourcing of materials for our product candidates,

manufacture of supplies for our preclinical and/or clinical studies, delays in clinical operations, which may include the availability or the continued availability of patients for our trials due to such things as quarantines, our conduct of patient monitoring and clinical trial data retrieval at investigational study sites.

The impacts of outbreaks are highly uncertain and cannot be predicted, and we cannot provide any assurance that any outbreak will not have a material adverse impact on our operations or future results or filings with regulatory health authorities. The extent of the impact to us, if any, will depend on future developments, including actions taken to contain the pathogen.

Risks Related to our Intellectual Property

If we are unable to adequately protect or enforce our intellectual property rights, or if we infringe the rights of others, our ability to commercialize our products could be impaired, and we may face significant costs and legal exposure.

Our success depends in part on our ability to obtain and maintain patent protection and trade secret rights for our product candidates and technologies, and to operate without infringing the intellectual property rights of others. If we are unable to secure or protect our proprietary rights, or if our rights are invalidated, circumvented, or challenged by third parties, our ability to develop and commercialize our products could be materially harmed.

Although we and our licensors have filed various patent applications covering our product candidates and technologies, there is no assurance that patents will be issued or, if issued, will provide meaningful protection. The scope, validity, and enforceability of patents involve complex legal and factual issues that are frequently litigated in the pharmaceutical and biotechnology industries. Patents that we own or license may be challenged, invalidated, or circumvented, and the patent applications we have filed may not result in issued patents. U.S. patent law remains subject to evolving judicial interpretation and administrative policy, and we may face interference proceedings to determine the priority of inventions. Additionally, delays in publication of patent applications and scientific discoveries may limit our ability to establish first inventorship.

We also rely on unpatented proprietary technology, know-how, and trade secrets, which may be difficult to protect. Disputes may arise with consultants, employees, or collaborators over rights to inventions or proprietary information, and these may not be resolved in our favor. Any failure to adequately protect this intellectual property could allow competitors to use our technologies without compensation and reduce our competitive advantage.

In addition to the risk of losing protection, we may be subject to claims that our technologies, products, or methods infringe on the proprietary rights of third parties. If we are found to infringe a valid patent or intellectual property right, we could be required to:

Even if such claims are without merit, defending against them can result in significant financial and management resource diversion and reputational damage. An adverse outcome in litigation could result in injunctions, substantial monetary liability, and loss of valuable intellectual property rights.

Furthermore, litigation or administrative proceedings, such as those before the U.S. Patent and Trademark Office, are inherently unpredictable. They are expensive, time-consuming, and may require disclosure of confidential information, which could harm our competitive position. Public announcements regarding such proceedings — regardless of outcome — could negatively affect investor perception and the market price of our common stock.

Overall, our inability to protect our own intellectual property rights, or avoid infringing the rights of others, could materially impair our ability to develop and commercialize our product candidates and could have a significant adverse effect on our business, financial condition, and results of operations.

Risks Related to Technology and Cybersecurity

Our strategy includes an increasing dependence on technology in our operations. If any of our key technology fails, our business could be adversely affected.

Our operations are increasingly dependent on technology. Our information technology systems are critical to our ability to develop our products and otherwise operating our business. Problems with the operation of the information or communication technology systems we use could adversely affect, or temporarily disable, all or a portion of our operations. Further, any systems failures could impede our ability to timely collect and report financial results in accordance with applicable laws.

A cybersecurity incident could negatively impact our business and our relationships with our employees, service providers, patients, clinical study sites and government agencies.

We use information technology and operational technology assets, including computer and information networks, in substantially all aspects of our business operations. We also use mobile devices, social networking and other online activities to connect with our employees, service providers, patients, clinical study sites and government agencies. Such uses give rise to cybersecurity risks, including security breach, espionage, system disruption, theft and inadvertent release of information. Our business involves the storage and transmission of numerous classes of sensitive and/or confidential information and intellectual property, including clinical trial participants’ personal information, private information about employees and financial and strategic information about us and our business partners. If we fail to assess and identify cybersecurity threats, we may become increasingly vulnerable to such threats. Additionally, while we have implemented measures to prevent security breaches and cyber incidents, our preventive measures and incident response efforts may not be entirely effective. Also, the regulatory environment surrounding information security and privacy is increasingly demanding, with the frequent imposition of new and constantly changing requirements. This changing regulatory landscape may cause increasingly complex compliance challenges, which may increase our compliance costs. Any failure to comply with these changing security and privacy laws and regulations could result in significant penalties, fines, legal challenges and reputational harm. The theft, destruction, loss, misappropriation, or release of sensitive and/or confidential information or intellectual property, or interference with our information technology systems or the technology systems of third parties on which we rely, could result in business disruption, negative publicity, brand damage, violation of privacy laws, loss of confidence, potential liability and competitive disadvantage.

Risks Related to Marketing Approval and Other Legal Compliance Matters

Even if we complete the necessary preclinical studies and clinical trials, the marketing approval process is expensive, time consuming and uncertain and may prevent us or any future collaborators from obtaining approvals for the commercialization of our current or future product candidates. As a result, we cannot predict when or if, and in which territories, we, or any future collaborators, will obtain marketing approval to commercialize a product candidate.

The research, testing, manufacturing, labeling, approval, selling, marketing, promotion and distribution of biopharmaceutical products are subject to extensive regulation by the FDA and comparable foreign regulatory authorities such as the EMA, which regulations differ from country to country. We, and any future collaborators, are not permitted to market our product candidates in the U.S. or in other countries until we, or they, receive approval of a biologics license application (“BLA”), NDA or marketing authorization from the FDA or marketing approval from applicable regulatory authorities outside the U.S. Product candidates in the development phase are subject to the risks of failure inherent in drug development. We have not received marketing approval for any of our product candidates in the U.S. or in any other jurisdiction. We have limited experience in filing and supporting the applications necessary to gain marketing approvals and expect to rely on third parties, including third-party clinical research and regulatory consultants, to assist us in this process.

The process of obtaining marketing approvals, both in the U.S. and abroad, is lengthy, expensive and uncertain. It may take many years, 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. Securing marketing approval requires the submission of extensive preclinical and clinical data and supporting information, including manufacturing information, to regulatory authorities for each therapeutic indication

to establish the product candidate’s safety and efficacy. The FDA or other regulatory authorities may determine that our product candidates are not safe and effective, only moderately effective or have undesirable or unintended side effects, toxicities or other characteristics that preclude our obtaining marketing approval or prevent or limit commercial use.

We will need to carefully review the guidance and advice that FDA and other regulatory and scientific authorities in foreign jurisdictions, including the Committee for Medicinal Products for Human Use (“CHMP”), provide in any meetings we have with those authorities to discuss our clinical development programs. Sponsors are given opportunities to meet with the FDA and other regulatory bodies at certain points in their development programs. At the conclusion of these meetings, the FDA and comparable regulatory authorities provide responses to questions posed by the sponsor regarding the clinical development program. They will not indicate whether an application will be approved, but will provide guidance to the sponsor on various questions, including what types of studies and data are likely necessary to support review and potential approval of an NDA, BLA or marketing authorization. For example, the FDA may express support for the sponsor’s approach in the clinical development program but indicate that questions concerning whether the data support approval will be subject to review by the agency following its acceptance for filing of the NDA or BLA. While such guidance is not legally binding, our failure to carefully consider these recommendations for the design of a clinical program may put the program at significant risk of failure.

Further, the FDA or other comparable foreign regulatory authorities may determine that we must provide additional evidence of safety or efficacy before approving a BLA, NDA or marketing authorization for our product candidates. For example, the FDA reviews an application to determine whether there is “substantial evidence” to support a finding of efficacy for the proposed product for its intended use(s). The FDA has interpreted this evidentiary standard to generally require at least two adequate and well-controlled clinical trials to establish efficacy of a new product. Under certain circumstances, however, the FDA has indicated that a single trial with certain characteristics and additional confirmatory evidence may satisfy this standard. The FDA issued draft guidance in September 2023 that outlines considerations for relying on confirmatory evidence in lieu of a second clinical trial to demonstrate efficacy. In the event that we submit a BLA, NDA or marketing authorization on the basis of one clinical trial and confirmatory evidence, the FDA or other comparable foreign regulatory authorities could determine that such information is not sufficient to support approval of the application and the agencies could require us to conduct an additional trial in support of the BLA, NDA or marketing authorization. In addition, if we are slow or unable to adapt to changes in existing requirements or the adoption of new requirements or policies governing clinical trials, our development plans may be impacted.

Further, in January 2022, the new Clinical Trials Regulation (EU) No 536/2014 became effective in the EU and replaced the prior Clinical Trials Directive 2001/20/EC. This regulation aims at simplifying and streamlining the authorization, conduct and transparency of clinical trials in the EU. Under the coordinated procedure for the approval of clinical trials, the sponsor of a clinical trial to be conducted in more than one EU member state will only be required to submit a single application for approval. The submission will be made through the Clinical Trials Information System, a clinical trials portal overseen by the EMA and available to clinical trial sponsors, competent authorities of the EU member states and the public. If we seek approval of our clinical trials in the EU pursuant to this regulation, there can be no assurance that we will be able to secure such an authorization for our product candidates.

Moreover, principal investigators for our clinical trials may serve as scientific advisors or consultants to us and receive compensation in connection with such services. Under certain circumstances, we may be required to report some of these relationships to the FDA or comparable foreign regulatory authorities. The FDA or a comparable foreign regulatory authority may conclude that a financial relationship between us and a principal investigator has created a conflict of interest or otherwise affected interpretation of the study. The FDA or comparable foreign regulatory authority may therefore question the integrity of the data generated at the applicable clinical trial site and the utility of the clinical trial itself may be jeopardized. This could result in a delay in approval, or rejection, of our marketing applications by the FDA or comparable foreign regulatory authority, as the case may be, and may ultimately lead to the denial of marketing approval of one or more of our product candidates.

Regulatory authorities 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 we, or any future collaborators, ultimately obtain may be limited or subject to restrictions or post-approval commitments that render the approved product not commercially viable.

Further, under the Pediatric Research Equity Act, an NDA or BLA, or supplement to an NDA or BLA, for certain drugs and biological products must contain data to assess the safety and efficacy of the drug or biological product in all relevant pediatric

subpopulations and to support dosing and administration for each pediatric subpopulation for which the product is safe and effective, unless the sponsor receives a deferral or waiver from the FDA. A deferral may be granted for several reasons, including a finding that the product or therapeutic candidate is ready for approval for use in adults before pediatric trials are complete or that additional safety or efficacy data needs to be collected before the pediatric trials begin. The applicable legislation in the EU also requires sponsors to either conduct clinical trials in a pediatric population in accordance with a Pediatric Investigation Plan approved by the Pediatric Committee of the EMA or to obtain a waiver or deferral from the conduct of these studies by this Committee. For any of our product candidates for which we are seeking marketing approval in the U.S. or Europe, we cannot guarantee that we will be able to obtain a waiver or alternatively complete any required studies and other requirements in a timely manner, or at all, which could result in associated reputational harm and subject us to enforcement action.

Any delay in obtaining or failure to obtain required approvals could negatively affect our ability or that of any future collaborators 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.

Failure to obtain marketing approval in foreign jurisdictions would prevent our product candidates from being marketed abroad. Any approval we may be granted for our product candidates in the U.S. would not assure approval of our product candidates in foreign jurisdictions and any of our product candidates that may be approved for marketing in a foreign jurisdiction will be subject to risks associated with foreign operations.

In order to market and sell our products in the EU and other foreign jurisdictions, we must obtain separate marketing approvals and comply with numerous and varying regulatory requirements. The approval procedure varies among countries and can involve additional testing. The time required to obtain approval may differ substantially from that required to obtain U.S. approval. The marketing approval process outside the U.S. generally includes similar risks as associated with obtaining FDA approval. We, and any future collaborators, may not obtain approvals from regulatory authorities outside the U.S. on a timely basis, if at all. Approval by the FDA does not ensure approval by regulatory authorities in other countries or jurisdictions, and approval by one regulatory authority outside the U.S. does not ensure approval by regulatory authorities in other countries or jurisdictions or by the FDA. We may file for marketing approvals but not receive necessary approvals to commercialize our products in any market.

In many countries outside the U.S., a product candidate must also be approved for reimbursement before it can be sold in that country. In some cases, the price that we intend to charge for our products, if approved, is also subject to approval. Obtaining non-U.S. marketing approvals and compliance with non-U.S. regulatory requirements could result in significant delays, difficulties and costs for us and could delay or prevent the introduction of our product candidates in certain countries. In addition, if we fail to obtain the non-U.S. approvals required to market our product candidates outside the U.S. or if we fail to comply with applicable non-U.S. regulatory requirements, our target markets will be reduced and our ability to realize the full market potential of our product candidates will be harmed and prospects may be adversely affected.

Additionally, we could face heightened risks with respect to obtaining marketing authorization in the United Kingdom (“UK”) as a result of the withdrawal of the UK from the EU, commonly referred to as “Brexit.” The UK is no longer part of the European Single Market and EU Customs Union. As of January 1, 2025, UK Medicines and Healthcare products Regulatory Agency (“MHRA”), is responsible for approving all medicinal products destined for the UK market (i.e., Great Britain and Northern Ireland). At the same time, a new international recognition procedure (“IPR”) will apply, which intends to facilitate approval of pharmaceutical products in the UK. The IRP is open to applicants that have already received an authorization for the same product from one of the MHRA’s specified Reference Regulators (“RRs”). The RRs notably include the EMA and regulators in the EU/European Economic Area (“EEA”), member states for approvals in the EU centralized procedure and mutual recognition procedure, as well as the FDA (for product approvals granted in the U.S.). Any delay in obtaining, or an inability to obtain, any approvals may force us or our collaborators to restrict or delay efforts to seek marketing approval in the UK for our product candidates, which could significantly and materially harm our business.

In addition, foreign regulatory authorities may change their approval policies and new regulations may be enacted. For instance, EU pharmaceutical legislation is currently undergoing a complete review process, in the context of the Pharmaceutical Strategy for Europe initiative, launched by the European Commission in November 2020. The European Commission’s proposal for revision of several legislative instruments related to medicinal products (among other things, potentially reducing the duration of regulatory data protection and revising the eligibility for expedited pathways) was published in April 2023. The proposed revisions remain to be agreed and adopted by the European Parliament and European Council and the proposals may therefore be substantially revised before

adoption, which is not anticipated before 2026. The revisions may however have a significant impact on the pharmaceutical industry and our business in the long term.

We expect that we will be subject to additional risks in commercializing any of our product candidates that receive marketing approval outside the U.S., including tariffs, trade barriers and regulatory requirements; economic weakness, including inflation, or political instability in particular foreign economies and markets (such as the war between Ukraine and Russia and the conflict in the Middle East); compliance with tax, employment, immigration and labor laws for employees living or traveling abroad; foreign currency fluctuations, which could result in increased operating expenses and reduced revenue, and other obligations incident to doing business in another country; and workforce uncertainty in countries where labor unrest is more common than in the U.S..

Any product candidate for which we obtain marketing approval would remain subject to ongoing regulation and could be subject to restrictions or withdrawal from the market, and we may be subject to substantial penalties if we fail to comply with regulatory requirements, when and if any of our product candidates are approved.

Any product candidate for which we obtain marketing approval will be subject to continual requirements of and review by the FDA and other regulatory authorities. These requirements include submissions of safety and other post-marketing information and reports, registration and listing requirements, cGMP requirements relating to quality control and manufacturing, quality assurance and corresponding maintenance of records and documents, and requirements regarding the distribution of samples to physicians and recordkeeping. In addition, the approval may be subject to limitations on the indicated uses for which the product may be marketed or to the conditions of approval or contain requirements for costly post-marketing testing and surveillance to monitor the safety or efficacy of the medicine, including the requirement to implement a REMS. Accordingly, if we receive marketing approval for one or more of our product candidates, we will continue to expend time, money and effort in all areas of regulatory compliance, including manufacturing, production, product surveillance and quality control. If we fail to comply with these requirements, we could have the marketing approvals for our products withdrawn by regulatory authorities and our ability to market any products could be limited, which could adversely affect our ability to achieve or sustain profitability.

We must also comply with requirements concerning advertising and promotion for any product candidate for which we obtain marketing approval. Promotional communications with respect to prescription products are subject to a variety of legal and regulatory restrictions and must be consistent with the information in the product’s approved labeling. The FDA and other agencies, including the Department of Justice, closely regulate and monitor the post-approval marketing and promotion of products to ensure that they are marketed and distributed only for the approved indications and in accordance with applicable laws.

In addition, later discovery of previously unknown adverse events or other problems with our products or their manufacturers or manufacturing processes, or failure to comply with regulatory requirements, may yield various results, including:

Non-compliance with EU requirements regarding safety monitoring or pharmacovigilance, and with requirements related to the development of products for the pediatric population, can also result in significant financial penalties. Similarly, failure to comply with the EU’s requirements regarding the protection of personal information can also lead to significant penalties and sanctions. Further, the marketing and promotion of authorized drugs, including industry-sponsored continuing medical education and advertising directed toward the prescribers of drugs and/or the general public, are strictly regulated in the EU and are also subject to EU member state laws. Direct-to-consumer advertising of prescription medicines is prohibited across the EU.

Accordingly, assuming we, or any future collaborators, receive marketing approval for one or more of our product candidates, we, and any future collaborators, and our and their contract manufacturers will continue to expend time, money and effort in all areas of regulatory compliance, including manufacturing, production, product surveillance and quality control. If we, and any future collaborators, are not able to comply with post-approval regulatory requirements, our or any future collaborators’ ability to market any future products could be limited, which could adversely affect our ability to achieve or sustain profitability. Further, the cost of compliance with post-approval regulations may have a negative effect on our operating results and financial condition.

We may seek certain designations for our product candidates, including Breakthrough Therapy, Regenerative Medicine Advanced Therapy (“RMAT”), Fast Track and Priority Review designations in the U.S., and the PRIority MEdicines (“PRIME”) designation in the EU, but we might not receive such designations, and even if we do, such designations may not lead to a faster development or regulatory review or approval process.

We may seek certain designations for one or more of our product candidates that could expedite review and approval by the FDA. A Breakthrough Therapy and RMAT product is defined as a product that is intended, alone or in combination with one or more other products, to treat a serious condition, and preliminary clinical evidence indicates that the product may demonstrate substantial improvement over existing therapies on one or more clinically significant endpoints, such as substantial treatment effects observed early in clinical development. For products that have been designated as Breakthrough and RMAT therapies, interaction and communication between the FDA and the sponsor of the trial can help to identify the most efficient path for clinical development while minimizing the number of patients placed in ineffective control regimens.

The FDA may also designate a product for Fast Track review if it is intended, whether alone or in combination with one or more other products, for the treatment of a serious or life-threatening disease or condition, and it demonstrates the potential to address unmet medical needs for such a disease or condition. For Fast Track products, sponsors may have greater interactions with the FDA and the FDA may initiate review of sections of a Fast Track product’s application before the application is complete. This rolling review may be available if the FDA determines, after preliminary evaluation of clinical data submitted by the sponsor, that a Fast Track product may be effective.

We may also seek a Priority Review designation for one or more of our product candidates. If the FDA determines that a product candidate would provide a significant improvement in safety or efficacy, the FDA may designate the product candidate for priority review. A priority review designation means that the goal for the FDA to review an application is six months, rather than the standard review period of ten months.

These designations are within the discretion of the FDA. Accordingly, even if we believe that one of our product candidates meets the criteria for these designations, the FDA may disagree and instead determine not to make such designation. Further, even if we receive a designation, the receipt of such designation for a product candidate may not result in a faster development or regulatory review or approval process compared to products considered for approval under conventional FDA procedures and does not assure

ultimate approval by the FDA. In addition, even if one or more of our product candidates qualifies for these designations, the FDA may, among other things, later decide that the product candidates no longer meet the conditions for qualification or decide that the time period for FDA review or approval will not be shortened. Further, obtaining any of these designations does not assure or increase the likelihood of the marketing approval by the FDA.

In the EU, we may seek PRIME designation for some of our product candidates in the future. PRIME is a voluntary program aimed at enhancing the EMA’s role to reinforce scientific and regulatory support in order to optimize development and enable accelerated assessment of new medicines that are of major public health interest with the potential to address unmet medical needs. The program focuses on medicines that target conditions for which there exists no satisfactory method of treatment in the EU or even if such a method exists, it may offer a major therapeutic advantage over existing treatments. PRIME is limited to medicines under development and not authorized in the EU and the applicant intends to apply for an initial marketing authorization application through the centralized procedure. To be accepted for PRIME, a product candidate must meet the eligibility criteria in respect of its major public health interest and therapeutic innovation based on information that is capable of substantiating the claims. The benefits of a PRIME designation include the appointment of a CHMP rapporteur to provide continued support and help to build knowledge ahead of a marketing authorization application, early dialogue and scientific advice at key development milestones, and the potential to qualify products for accelerated review, meaning reduction in the review time for an opinion on approvability to be issued earlier in the application process. PRIME enables an applicant to request parallel EMA scientific advice and health technology assessment advice to facilitate timely market access. Even if we receive PRIME designation for any of our product candidates, the designation may not result in a materially faster development process, review or approval compared to conventional EMA procedures. Further, obtaining PRIME designation does not assure or increase the likelihood of EMA’s grant of a marketing authorization.

We may seek approval of our product candidates from the FDA or comparable foreign regulatory authorities through the use of accelerated development pathways. If we are not able to use such pathways, we may be required to conduct additional clinical trials beyond those that are contemplated, which would increase the expense of obtaining, and delay or prevent the receipt of, necessary marketing approvals. Moreover, even if we receive accelerated approval from the FDA or comparable foreign regulatory authorities, if our confirmatory trials do not verify clinical benefit, or if we do not comply with rigorous post-marketing requirements, the FDA or comparable foreign regulatory authorities may seek to withdraw accelerated approval.

Under the Federal Food, Drug, and Cosmetic Act (“FDCA”) and implementing regulations, the FDA may grant accelerated approval to a product candidate designed to treat a serious or life-threatening condition that provides meaningful therapeutic benefit over available therapies upon a determination that the product candidate has an effect on a surrogate endpoint or intermediate clinical endpoint that is reasonably likely to predict clinical benefit. The FDA considers a clinical benefit to be a positive therapeutic effect that is clinically meaningful in the context of a given disease, such as irreversible morbidity or mortality. For the purposes of accelerated approval, a surrogate endpoint is a marker, such as a laboratory measurement, radiographic image, physical sign or other measure that is thought to predict clinical benefit, but is not itself a measure of clinical benefit. An intermediate clinical endpoint is a clinical endpoint that can be measured earlier than an effect on irreversible morbidity or mortality that is reasonably likely to predict an effect on irreversible morbidity or mortality or other clinical benefit measurement of a therapeutic effect that is considered reasonably likely to predict the clinical benefit. Prior to seeking such accelerated approval, we will continue to seek feedback from the FDA or comparable foreign regulatory agencies and otherwise evaluate our, or their, ability to seek and receive such accelerated approval.

There can be no assurance that the FDA or foreign regulatory agencies will agree with our surrogate endpoints or intermediate clinical endpoints in any of our clinical trials, or that we will decide to pursue or submit any additional NDAs or BLAs seeking accelerated approval. Similarly, there can be no assurance that, after feedback from the FDA or comparable foreign regulatory agencies, we will continue to pursue or apply for accelerated approval. Furthermore, for any submission of an application for accelerated approval, there can be no assurance that such submission will be accepted for filing or that any expedited development, review or approval will be granted on a timely basis, or at all. Finally, there can be no assurance that we will satisfy all FDA requirements, including new provisions, that govern accelerated approval.

In the EU, a “conditional” marketing authorization may be granted in cases where all the required safety and efficacy data are not yet available. A conditional marketing authorization is subject to conditions to be fulfilled for generating missing data or ensuring increased safety measures. A conditional marketing authorization is valid for one year and has to be renewed annually until fulfillment of all relevant conditions. Once the applicable pending studies are provided, a conditional marketing authorization can become a “standard” marketing authorization. However, if the conditions are not fulfilled within the timeframe set by the EMA, the marketing authorization will cease to be renewed.

Accordingly, a failure to obtain and maintain accelerated approval or any other form of expedited development, review or approval for our product candidates, or withdrawal of a product candidate, would result in a longer time period until commercialization of such product candidate, could increase the cost of development of such product candidate and could harm our competitive position in the marketplace.

We may seek a priority review voucher (“PRV”), for our current and future product candidates. A BLA or NDA for our current and future product candidates will not, however, meet the eligibility criteria for a PRV, unless we secure the applicable designation and approval of the BLA or NDA for the product candidate.

Congress has authorized the FDA to award PRVs to sponsors of certain drugs for tropical diseases or rare pediatric diseases or to use as medical countermeasures that meet the criteria specified in the law. This provision is designed to encourage development of new drug and biological products for prevention and treatment of certain tropical diseases, rare pediatric diseases and illnesses related to public health emergencies. Specifically, under this program, a sponsor who receives approval for a new drug or biologic for a tropical diseases, rare pediatric diseases or illnesses related to a public health emergency may qualify for a PRV, which can be redeemed for priority review of a subsequent marketing application for a different product. The sponsor that receives a PRV may transfer, including by sale, the PRV to another sponsor and that PRV may be further transferred any number of times before it is used. A PRV entitles the holder to designate a single human drug application submitted under Section 505(b)(1) of the FDCA or Section 351 of the Public Health Service Act as qualifying for a priority review. An FDA priority review may expedite the review process of a marketing application reducing the review time from ten months after formal acceptance of the file to six months after formal acceptance of the file.

In order for a sponsor to receive a PRV in connection with approval of a BLA or NDA, the BLA or NDA must be for a product that does not include a previously approved active ingredient in addition to meeting other applicable requirements.

We and our contract manufacturers are subject to significant regulation. The manufacturing facilities on which we rely may not continue to meet regulatory requirements, which could materially harm our business.

All entities involved in the preparation of product candidates, including drug substance, drug product and device combinations that may be used in combination with our product candidates, for clinical trials or commercial sale, including any contract manufacturers, are subject to extensive regulation. Components of a finished therapeutic product approved for commercial sale or used in late-stage clinical trials must be manufactured in accordance with cGMPs. These regulations govern manufacturing processes and procedures (including record keeping) and the implementation and operation of quality systems to control and assure the quality of investigational products and products approved for sale. Poor control of production processes can lead to the introduction of adventitious agents or other contaminants or to inadvertent changes in the properties or stability of our product candidates that may not be detectable in final product testing.

We or our contract manufacturers must supply all necessary documentation in support of a BLA or NDA on a timely basis and must adhere to the FDA’s current good laboratory practices and cGMP regulations enforced through its facilities inspection program. Our facilities and quality systems and the facilities and quality systems of some or all of our contract manufacturers must pass a pre-approval inspection for compliance with the applicable regulations as a condition of marketing approval of any product candidate. In addition, the regulatory authorities may, at any time, audit or inspect a manufacturing facility involved with the preparation of our product candidates or the associated quality systems for compliance with the regulations applicable to the activities being conducted. If these facilities do not pass a pre-approval plant inspection, FDA approval of the products will not be granted.

The regulatory authorities also may, at any time following approval of a product for sale, audit our manufacturing facilities or those of our contract manufacturers. If any such inspection or audit identifies failure to comply with applicable regulations or if a violation of our product specifications or applicable regulations occurs independent of such an inspection or audit, we or the relevant regulatory authority may require remedial measures that may be costly and/or time-consuming for us or a third-party to implement and that may include the temporary or permanent suspension of a clinical trial or commercial sales or the temporary or permanent closure of a facility, which may lead to temporary or permanent supply shortages. Any such remedial measures imposed upon us or third parties with whom we contract could materially harm our business.

If we or our third-party manufacturers fail to maintain regulatory compliance, the FDA can impose regulatory sanctions including, among other things, refusal to approve a pending application for a new product, or revocation of a pre-existing approval. Any such consequence would severely harm our business, financial condition and results of operations.

Inadequate funding for the FDA, the SEC and other government agencies, including from government shutdowns, competing priorities or other disruptions to these agencies’ operations, and regulatory reform efforts, could hinder their ability to hire and retain key leadership and other personnel, prevent new products and services from being developed or commercialized in a timely manner or otherwise prevent those agencies from performing normal business functions on which the operation of our business may rely, which could negatively impact our business.

The ability of the FDA to review and approve new products can be affected by a variety of factors, including government budget and funding levels, ability to hire and retain key personnel and accept the payment of user fees, and statutory, regulatory and policy changes. Average review times at the FDA have fluctuated in recent years as a result. Disruptions at the FDA and other agencies may also slow the time necessary for new product candidates to be reviewed and/or approved by necessary government agencies, which would adversely affect our business. In addition, government funding of the SEC and other government agencies, including government agencies and regulatory authorities outside the U.S., on which our operations may rely, including those that fund research and development activities, is subject to the political process, which is inherently fluid and unpredictable. Further, while the FDA’s review of NDAs and BLAs is funded by the user fee program established under the Prescription Drug User Fee Act (“PDUFA”), the Trump Administration has indicated that it will be reviewing that program and its implementation.

In addition, disruptions may result from events similar to the COVID-19 pandemic. During the COVID-19 pandemic, a number of companies announced receipt of complete response letters due to the FDA’s inability to complete required inspections for their applications. In the event of a similar public health emergency in the future, the FDA may not be able to continue its current pace and review timelines could be extended. Regulatory authorities outside the U.S. facing similar circumstances may adopt similar restrictions or other policy measures in response to a similar public health emergency and may also experience delays in their regulatory activities.

Disruptions or competing priorities at the FDA and other agencies may also slow the time necessary for new product candidates to be reviewed and/or approved by necessary government agencies, which would adversely affect our business. For example, over the last several years the U.S. government has shut down several times and certain regulatory agencies, such as the FDA and the SEC, have had to furlough critical FDA, SEC and other government employees and stop critical activities. If a prolonged government shutdown occurs, it could significantly impact the ability of the FDA to timely review and process our regulatory submissions, which could have a material adverse effect on our business. Further, future government shutdowns could impact our ability to access the public markets and obtain necessary capital in order to properly capitalize and continue our operations.

If a prolonged government shutdown or other disruption occurs, it could significantly impact the ability of the FDA to timely review and process our regulatory submissions, which could have a material adverse effect on our business. Future shutdowns or other disruptions could also affect other government agencies such as the SEC, which may also impact our business by delaying review of our public filings, to the extent such review is necessary, and our ability to access the public markets.

Current and future legislation may increase the difficulty and cost for us to obtain reimbursement for any of our product candidates that do receive marketing approval.

In the U.S. and foreign jurisdictions, there have been a number of legislative and regulatory changes and proposed changes regarding the healthcare system that could prevent or delay marketing approval of our product candidates, restrict or regulate post-approval activities and affect our ability to profitably sell any product candidates for which we obtain marketing approval. We expect that current laws, as well as other healthcare reform measures that may be adopted in the future, may result in more rigorous coverage criteria and in additional downward pressure on the price that we may receive for any approved products. If reimbursement of our products is unavailable or limited in scope, our business could be materially harmed.

We expect that recent healthcare reforms, as well as other healthcare reform measures that may be adopted in the future, may result in additional reductions in Medicare and other healthcare funding, more rigorous coverage criteria, new payment methodologies and additional downward pressure on the price that we receive for any approved product and/or the level of reimbursement physicians receive for administering any approved product we might bring to market. Reductions in reimbursement levels may negatively impact the prices we receive or the frequency with which our products are prescribed or administered. Any reduction in reimbursement from Medicare or other government programs may result in a similar reduction in payments from private payors. Accordingly, such reforms, if enacted, could have an adverse effect on anticipated revenue from product candidates that we may successfully develop and for which we may obtain marketing approval and may affect our overall financial condition and ability to develop or commercialize product candidates.

The prices of prescription pharmaceuticals in the U.S. and foreign jurisdictions are subject to considerable legislative and executive actions and could impact the prices we obtain for our products, if and when licensed.

The prices of prescription pharmaceuticals have been the subject of considerable discussion in the U.S. There have been several Congressional inquiries, as well as proposed and enacted state and federal legislation designed to, among other things, bring more transparency to pharmaceutical pricing, review the relationship between pricing and manufacturer patient programs, and reduce the costs of pharmaceuticals under Medicare and Medicaid.

At the state level, individual states are increasingly aggressive in passing legislation and implementing regulations designed to control pharmaceutical and biological product 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. This is increasingly true with respect to products approved pursuant to the accelerated approval pathway. State Medicaid programs and other payers are developing strategies and implementing significant coverage barriers, or refusing to cover these products outright, arguing that accelerated approval drugs have insufficient or limited evidence despite meeting the FDA’s standards for accelerated approval. In addition, regional healthcare organizations and individual hospitals are increasingly using bidding procedures to determine what pharmaceutical products and which suppliers will be included in their prescription drug and other healthcare programs. These measures could reduce the ultimate demand for our products, once approved, or put pressure on our product pricing. We expect that additional state and federal healthcare reform measures will be adopted in the future, any of which could limit the amounts that federal and state governments will pay for healthcare products and services, which could result in reduced demand for our product candidates or additional pricing pressures.

In the EU, similar political, economic and regulatory developments may affect our ability to profitably commercialize our product candidates, if approved. In markets outside of the U.S. and the EU, reimbursement and healthcare payment systems vary significantly by country, and many countries have instituted price ceilings on specific products and therapies. In many countries, including those of the EU, the pricing of prescription pharmaceuticals is subject to governmental control and access. In these countries, pricing negotiations with governmental authorities can take considerable time after the receipt of marketing approval for a product. To obtain reimbursement or pricing approval in some countries, we or our collaborators may be required to conduct a clinical trial that compares the cost-effectiveness of our product to other available therapies. If reimbursement of our products is unavailable or limited in scope or amount, or if pricing is set at unsatisfactory levels, our business could be materially harmed.

The insurance coverage and reimbursement status of newly approved products is uncertain. Our product candidates, if approved, may become subject to unfavorable pricing regulations, third-party coverage and reimbursement practices or healthcare reform initiatives, which would harm our business. Failure to obtain or maintain coverage and adequate reimbursement for any of our product candidates for which we obtain approval could limit our ability to market those products and decrease our ability to generate revenue.

The regulations that govern marketing approvals, pricing, coverage and reimbursement for new drugs and other medical products vary widely from country to country. In the U.S., healthcare reform legislation may significantly change the approval requirements in ways that could involve additional costs and cause delays in obtaining approvals. Some countries require approval of the sale price of a product before it can be marketed. In many countries, the pricing review period begins after marketing or product licensing approval is granted. In some foreign markets, pricing remains subject to continuing governmental control even after initial approval is granted. As a result, we might obtain marketing approval for a product in a particular country, but then be subject to price regulations that delay our commercial launch of the product, possibly for lengthy time periods, and negatively impact the revenue we are able to generate from the sale of the product in that country. Adverse pricing limitations may hinder our ability to recoup our investment in one or more products or product candidates, even if any product candidates we may develop obtain marketing approval.

Our ability to successfully commercialize our products and product candidates also will depend in part on the extent to which coverage and adequate reimbursement for these products and related treatments will be available from government health administration authorities, private health insurers and other organizations. Government authorities and third-party payors, such as private health insurers and health maintenance organizations, decide which medications they will pay for and establish reimbursement levels. Sales of any product we successfully develop will depend substantially, both domestically and abroad, on the extent to which the costs of such product will be paid by health maintenance, managed care, pharmacy benefit and similar healthcare management organizations, or reimbursed by government health administration authorities, private health coverage insurers and other third-party payors. If coverage and adequate reimbursement is not available, or is available only to limited levels or only after clearing significant barriers, such as the requirement to fail on other products before providing reimbursement, we may not be able to successfully

commercialize any product we may successfully develop. Even if coverage is provided, the approved reimbursement amount may not be high enough to allow us to establish or maintain pricing sufficient to realize a sufficient return on our investment. A primary trend in the U.S. healthcare industry and elsewhere is cost containment. Government authorities and third-party payors have attempted to control costs by limiting coverage and the amount of reimbursement for particular medications. In many countries, the prices of medical products are subject to varying price control mechanisms as part of national health systems. In general, the prices of medicines under such systems are substantially lower than in the U.S. Other countries allow companies to fix their own prices for medicines, but monitor and control company profits. Additional foreign price controls or other changes in pricing regulation could restrict the amount that we are able to charge for any product we may successfully develop. Accordingly, in markets outside the U.S., the reimbursement for products may be reduced compared with the U.S. and may be insufficient to generate commercially reasonable revenues and profits.

There is also significant uncertainty related to the insurance coverage and reimbursement of newly approved products and coverage may be more limited than the purposes for which the medicine is approved by the FDA or comparable foreign regulatory authorities. In the U.S., the principal decisions about reimbursement for new medicines are typically made by the Centers for Medicare and Medicaid Services (“CMS”). CMS decides whether and to what extent a new medicine will be covered and reimbursed under Medicare and private payors tend to follow CMS to a substantial degree. No uniform policy of coverage and reimbursement for products exists among third-party payors and coverage and reimbursement levels for products can differ significantly from payer to payer. As a result, the coverage determination process is often a time consuming and costly process that may require us to provide scientific and clinical support for the use of any product we may successfully develop to each payer separately, with no assurance that coverage and adequate reimbursement will be applied consistently or obtained in the first instance.

In the Europe and in the rest of the world, pricing and reimbursement schemes vary widely from country to country and may be more conservative than CMS. Moreover, eligibility for reimbursement does not imply that any drug will be paid for in all cases or at a rate that covers our costs, including research, development, manufacture, sale and distribution. Interim reimbursement levels for new drugs, if applicable, may also not be sufficient to cover our costs and may not be made permanent. Reimbursement rates may vary according to the use of the drug and the clinical setting in which it is used, may be based on reimbursement levels already set for lower cost drugs and may be incorporated into existing payments for other services. Our inability to promptly obtain coverage and profitable payment rates from both government-funded and private payors any product we may successfully develop could have a material adverse effect on our operating results, our ability to raise capital needed to commercialize product candidates and our overall financial condition.

Further, some countries provide that products may be marketed only after a reimbursement price has been agreed. Some countries may require the completion of additional studies that compare the cost-effectiveness of a particular drug candidate to currently available therapies or so-called health technology assessments, in order to obtain reimbursement or pricing approval. There can be no assurance that any country that has price controls or reimbursement limitations for pharmaceutical products will allow favorable reimbursement and pricing arrangements for any products, if approved in those countries.

Finally, net prices for drugs may be reduced by mandatory discounts or rebates required by government healthcare programs or private payors and by any future relaxation of laws that presently restrict imports of drugs from countries where they may be sold at lower prices than in the U.S. Our inability to promptly obtain coverage and profitable reimbursement rates from third-party payors for any product we may successfully develop could have a material adverse effect on our operating results, our ability to raise capital needed to commercialize products and our overall financial condition.

Increasingly, third-party payors are requiring that pharmaceutical companies provide them with predetermined discounts from list prices and are challenging the prices charged for medical products. We cannot be sure that reimbursement will be available for any product candidate that we commercialize and, if reimbursement is available, the level of reimbursement. Reimbursement may impact the demand for, or the price of, any product candidate for which we obtain marketing approval. In order to obtain reimbursement, physicians may need to show that patients have superior treatment outcomes with our products compared to standard of care drugs, including lower-priced generic versions of standard of care drugs. We may experience pricing pressures in connection with the sale of any of our product candidates, due to the trend toward managed healthcare, the increasing influence of health maintenance organizations and additional legislative changes. The downward pressure on healthcare costs in general, particularly prescription drugs and surgical procedures and other treatments, has become very intense. As a result, increasingly high barriers are being erected to the entry of new products.

We may be subject to certain healthcare laws and regulations, which could expose us to criminal sanctions, civil penalties, contractual damages, reputational harm, fines, disgorgement, exclusion from participation in government healthcare programs, curtailment or restricting of our operations, and diminished profits and future earnings.

Healthcare providers, third-party payors and others will play a primary role in the recommendation and prescription of any products for which we obtain marketing approval. Our future arrangements with healthcare providers and third-party payors will expose us to broadly applicable fraud and abuse and other healthcare laws and regulations that may constrain the business or financial arrangements and relationships through which we market, sell and distribute any products for which we obtain marketing approval. Potentially applicable U.S. federal and state healthcare laws and regulations include the following:

Anti-Kickback Statute. The federal Anti-Kickback Statute prohibits, among other things, persons and entities from knowingly and willfully soliciting, offering, receiving or providing remuneration, directly or indirectly, in cash or in kind, to induce or reward 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 healthcare programs such as Medicare and Medicaid. A person or entity does not need to have actual knowledge of the federal Anti-Kickback Statute or specific intent to violate it in order to have committed a violation.

False Claims Laws. The federal false claims laws, including the civil False Claims Act, impose criminal and civil penalties, including those from civil whistleblower or qui tam actions against individuals or entities for knowingly presenting, or causing to be presented to the federal government, claims for payment that are false or fraudulent or making a false statement to avoid, decrease or conceal an obligation to pay money to the federal government. In addition, the government may assert that a claim including items or services resulting from a violation of the federal Anti- Kickback Statute constitutes a false or fraudulent claim for purposes of the False Claims Act.

HIPAA. The federal Health Insurance Portability and Accountability Act of 1996 (“HIPAA”) imposes criminal and civil liability for executing or attempting to execute a scheme to defraud any healthcare benefit program. In addition, HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act, also imposes obligations on certain types of individuals and entities, including mandatory contractual terms, with respect to safeguarding the privacy, security and transmission of individually identifiable health information.

False Statements Statute. The federal false statements statute prohibits knowingly and willfully falsifying, concealing or covering up a material fact or making any materially false statement in connection with the delivery of or payment for healthcare benefits, items or services.

Transparency Requirements. The federal Physician Payments Sunshine Act requires certain manufacturers of 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 Department of Health and Human Services (“HHS”) information related to physician and healthcare provider payments and other transfers of value and physician ownership and investment interests.

Analogous State and Foreign Laws. Analogous state laws and regulations, such as state anti-kickback and false claims laws, and transparency laws, may apply to sales or marketing arrangements, and claims involving healthcare items or services reimbursed by non-governmental third-party payors, including private insurers, and some state laws require pharmaceutical companies to comply with the pharmaceutical industry’s voluntary compliance guidelines and the relevant compliance guidance promulgated by the federal government, in addition to requiring manufacturers to report information related to payments to physicians and other healthcare providers or marketing expenditures. Many state laws also govern the privacy and security of health information in some circumstances, many of which differ from each other in significant ways and often are not preempted by HIPAA, thus complicating compliance efforts. Foreign laws also govern the privacy and security of health information in many circumstances.

The provision of benefits or advantages to physicians to induce or encourage the prescription, recommendation, endorsement, purchase, supply, order or use of medicinal products is prohibited in the EU. Payments made to physicians in certain EU member states must be publicly disclosed. Moreover, agreements with physicians often must be the subject of prior notification and approval by the physician’s employer, his or her competent professional organization and/or the regulatory authorities of the individual EU member states. These requirements are provided in the national laws, industry codes or professional codes of conduct applicable in the EU member states. Failure to comply with these requirements could result in reputational risk, public reprimands, administrative penalties, fines or imprisonment.

Efforts to ensure that our business arrangements with third parties, and our business generally, will comply with applicable healthcare laws and regulations will 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, damages, corporate integrity or other similar forms of agreements or decrees, fines, imprisonment, exclusion of products from government funded healthcare programs, such as Medicare and Medicaid, disgorgement, contractual damages, and reputational harm, any of which could substantially disrupt our operations. If any of the physicians or other providers or entities with whom we expect to do business is found not to be in compliance with applicable laws, they may be subject to criminal, civil or administrative sanctions, including exclusions from government funded healthcare programs.

We are subject to stringent privacy laws, information security laws, regulations, policies and contractual obligations related to data privacy and security and changes in such laws, regulations, policies, contractual obligations and failure to comply with such requirements could subject us to significant fines and penalties, which may have a material adverse effect on our business, financial condition or results of operations.

We are subject to data privacy and protection laws and regulations that apply to the collection, transmission, storage and use of personally-identifying information, which among other things, impose certain requirements relating to the privacy, security and transmission of personal information, including comprehensive regulatory systems in the U.S., EU and the UK. The legislative and regulatory landscape for privacy and data protection continues to evolve in jurisdictions worldwide, and there has been an increasing focus on privacy and data protection issues with the potential to affect our business. Failure to comply with any of these laws and regulations could result in enforcement action against us, including fines, claims for damages by affected individuals, damage to our reputation and loss of goodwill, any of which could have a material adverse effect on our business, financial condition, results of operations or prospects.

There are numerous U.S. federal and state laws and regulations related to the privacy and security of personal information that may impact certain of our business operations. For example, regulations promulgated pursuant to HIPAA establish privacy and security standards that limit the use and disclosure of individually identifiable health information, or protected health information, and require the implementation of administrative, physical, and technological safeguards to protect the privacy of protected health information and ensure the confidentiality, integrity, and availability of electronic protected health information. Determining whether protected health information has been handled in compliance with applicable privacy standards and our contractual obligations can be complex and may be subject to changing interpretation. These obligations may be applicable to some or all of our business activities now or in the future.

If we fail to comply with applicable privacy laws, including applicable HIPAA privacy and security standards, we could face civil and criminal penalties. Enforcement activity can result in financial liability and reputational harm, and responses to such enforcement activity can consume significant internal resources. We cannot be sure how these regulations will be interpreted, enforced or applied to our operations. In addition to the risks associated with enforcement activities and potential contractual liabilities, our ongoing efforts to comply with evolving laws and regulations at the federal and state level may be costly and require ongoing modifications to our policies, procedures and systems.

In addition to potential enforcement by the HHS, we could also be potentially subject to privacy enforcement from the Federal Trade Commission (the “FTC”). The FTC has been particularly focused on the unpermitted processing of health and genetic data through its recent enforcement actions and is expanding the types of privacy violations that it interprets to be “unfair” under Section 5 of the FTC Act, as well as the types of activities it views to trigger the Health Breach Notification Rule (which the FTC also has the authority to enforce). The agency is also in the process of developing rules related to commercial surveillance and data security. We will need to account for the FTC’s evolving rules and guidance for proper privacy and data security practices in order to mitigate risk for a potential enforcement action, which may be costly. Finally, both the FTC and HHS’s enforcement priorities (as well as those of other federal regulators) may be impacted by the change in administration and new leadership. These shifts in enforcement priorities may also impact our business.

There are also increased restrictions at the federal level relating to transferring sensitive data outside of the U.S. to certain foreign countries. Failure to comply with these rules can lead to a potential FTC enforcement action. These data transfer restrictions (and others that may pass in the future) may create operational challenges and legal risks for our business.

There also are state privacy and security laws that also may be applicable to our business activities now or in the future. These laws may impact our business activities, including our identification of research subjects, relationships with business partners and ultimately the marketing and distribution of our products.

Similar to the laws in the U.S., there are significant privacy and data security laws that apply in Europe and other countries which we will need to navigate.

Data privacy remains an evolving landscape at both the domestic and international level, with new regulations coming into effect and continued legal challenges, and our efforts to comply with the evolving data protection rules may be unsuccessful. It is possible that these laws may be interpreted and applied in a manner that is inconsistent with our practices. We must devote significant resources to understanding and complying with this changing landscape. Failure to comply with laws regarding data protection would expose us to risk of enforcement actions taken by data protection authorities in the EEA and elsewhere and carries with it the potential for significant penalties if we are found to be non-compliant. Similarly, failure to comply with federal and state laws in the U.S. regarding privacy and security of personal information could expose us to penalties under such laws. Any such failure to comply with data protection and privacy laws could result in government-imposed fines or orders requiring that we change our practices, claims for damages or other liabilities, regulatory investigations and enforcement action, litigation and significant costs for remediation, any of which could adversely affect our business. Even if we are not determined to have violated these laws, government investigations into these issues typically require the expenditure of significant resources and generate negative publicity, which could harm our business, financial condition, results of operations or prospects.

We are subject to U.S. and foreign anti-corruption and anti-money laundering laws with respect to our operations and non-compliance with such laws can subject us to criminal and/or civil liability and harm our business.

We are subject to the Foreign Corrupt Practices Act, the U.S. domestic bribery statute contained in 18 U.S.C. § 201, the U.S. Travel Act, the USA PATRIOT Act, and other state and national anti-bribery and anti-money laundering laws in countries in which we conduct activities. Anti-corruption laws are interpreted broadly and prohibit companies and their employees, agents, third-party intermediaries, joint venture partners and collaborators from authorizing, promising, offering or providing, directly or indirectly, improper payments or benefits to recipients in the public or private sector. We may have direct or indirect interactions with officials and employees of government agencies or government-affiliated hospitals, universities and other organizations. In addition, we may engage third-party intermediaries to promote our clinical research activities abroad and/or to obtain necessary permits, licenses, and other regulatory approvals. We can be held liable for the corrupt or other illegal activities of these third-party intermediaries, our employees, representatives, contractors, partners and agents, even if we do not explicitly authorize or have actual knowledge of such activities.

Noncompliance with anti-corruption and anti-money laundering laws could subject us to whistleblower complaints, investigations, sanctions, settlements, prosecution, other enforcement actions, disgorgement of profits, significant fines, damages, other civil and criminal penalties or injunctions, suspension and/or debarment from contracting with certain persons, the loss of export privileges, reputational harm, adverse media coverage and other collateral consequences. If any subpoenas, investigations or other enforcement actions are launched, or governmental or other sanctions are imposed, or if we do not prevail in any possible civil or criminal litigation, our business, results of operations and financial condition could be materially harmed. In addition, responding to any action will likely result in a materially significant diversion of management’s attention and resources and significant defense and compliance costs and other professional fees. In certain cases, enforcement authorities may even cause us to appoint an independent compliance monitor which can result in added costs and administrative burdens.

Various laws, regulations and executive orders also restrict the use and dissemination outside of the U.S., or the sharing with certain non-U.S. nationals, of information classified for national security purposes, as well as certain products and technical data relating to those products. Further, the provision of benefits or advantages to physicians to induce or encourage the prescription, recommendation, endorsement, purchase, supply, order, or use of medicinal products is prohibited in the EU. The provision of benefits or advantages to physicians is also governed by the national anti-bribery laws of EU member states and the U.K. Bribery Act 2010. Violations of these laws could result in substantial fines and imprisonment. Payments made to physicians in certain EU member states must be publicly disclosed. Moreover, agreements with physicians often must be the subject of prior notification and approval by the physician’s employer, his or her competent professional organization, and/or the regulatory authorities of the individual EU member states. These requirements are provided in the national laws, industry codes, or professional codes of conduct applicable in the EU member states. Failure to comply with these requirements could result in reputational risk, public reprimands, administrative penalties, fines, or imprisonment.

If we fail to comply with environmental, health and safety laws and regulations, we could become subject to fines or penalties or incur costs that could significantly harm our business.

We are subject to numerous environmental, health and safety laws and regulations, including those governing laboratory procedures and the handling, use, storage, treatment and disposal of hazardous materials and wastes. From time to time and in the future, our operations may involve the use of hazardous and flammable materials, including chemicals and biological materials, and may also produce hazardous waste products. Even if we contract with third parties for the disposal of these materials and waste products, we cannot completely eliminate the risk of contamination or injury resulting from these materials. In the event of contamination or injury resulting from the use or disposal of our hazardous materials, we could be held liable for any resulting damages, and any liability could exceed our resources. We also could incur significant costs associated with civil or criminal fines and penalties for failure to comply with such laws and regulations.

We maintain workers’ compensation insurance to cover us for costs and expenses we may incur due to injuries to our employees resulting from the use of hazardous materials, but this insurance may not provide adequate coverage against potential liabilities. However, we do not maintain insurance for environmental liability or toxic tort claims that may be asserted against us.

In addition, we may incur substantial costs in order to comply with current or future environmental, health and safety laws and regulations. Current or future environmental laws and regulations may impair our research, development or production efforts, which could adversely affect our business, financial condition, results of operations or prospects. In addition, failure to comply with these laws and regulations may result in substantial fines, penalties or other sanctions.

Our employees, independent contractors, CROs, consultants, contract manufacturers, commercial partners, vendors and principal investigators may engage in misconduct or other improper activities, including non-compliance with regulatory standards and requirements.

We are exposed to the risk of fraud or other misconduct by our employees, independent contractors, CROs, consultants, contract manufacturers, commercial partners, vendors and, if we commence clinical trials, our principal investigators. Misconduct by these parties could include intentional failures to comply with FDA regulations or the regulations applicable in the EU and other jurisdictions, provide accurate information to the FDA, the European Commission and other regulatory authorities, comply with healthcare fraud and abuse laws and regulations in the U.S. and abroad, report financial information or data accurately, or disclose unauthorized activities to us. In particular, sales, marketing and business arrangements in the healthcare industry are subject to extensive laws and regulations intended to prevent fraud, misconduct, kickbacks, self-dealing and other abusive practices. These laws and regulations restrict or prohibit a wide range of pricing, discounting, marketing and promotion, sales commission, customer incentive programs and other business arrangements.

Such misconduct also could involve the improper use of information obtained in the course of clinical trials or interactions with the FDA or other regulatory authorities, which could result in regulatory sanctions and cause serious harm to our reputation. Even with appropriate policies and procedures, it is not always possible to identify and deter misconduct, and the precautions we take to detect and prevent such activity may not be effective in controlling unknown or unmanaged risks or losses or in protecting us from government investigations or other actions or lawsuits stemming from a failure to comply with these 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 have a significant impact on our business, financial condition, results of operations and prospects, including the imposition of significant fines or other sanctions.

Risks Related to this Offering

The price of our common stock may be highly volatile.

The market price of our securities, like that of many other research and development public pharmaceutical and biotechnology companies, has been highly volatile and the price of our common stock may be volatile in the future due to a wide variety of factors, including:

Since January 1, 2024, the closing stock price of our common stock has fluctuated between a high of $15.04 per share to a low of $1.12 per share. On September 15, 2025, the last reported sale price of our common stock on The Nasdaq Capital Market was $2.75 per share. The fluctuation in the price of our common stock has sometimes been unrelated or disproportionate to our operating performance. In addition, potential dilutive effects of future sales of shares of common stock and warrants by us, as well as potential sale of common stock by the holders of warrants and options, could have an adverse effect on the market price of our shares.

If we fail to regain compliance to meet Nasdaq’s listing requirements, we could be removed from The Nasdaq Capital Market, which would limit the ability of broker-dealers to sell our securities and the ability of shareholders to sell their securities in the secondary market and negatively impact our ability to raise capital.

Companies trading on Nasdaq, such as our Company, must be reporting issuers under Section 12 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and must meet the listing requirements in order to maintain the listing of common stock on The Nasdaq Capital Market. If we do not meet these requirements, the market liquidity for our securities could be severely adversely affected by limiting the ability of broker-dealers to sell our securities and the ability of shareholders to sell their securities in the secondary market.

On August 15, 2025, we received the Notice from Nasdaq advising us that we were not in compliance with the Stockholders’ Equity Requirement. Pursuant to the Notice, Nasdaq has gave us 45 calendar days from the date of the Notice, or until September 29, 2025, to submit to Nasdaq a plan to regain compliance. If our plan is accepted, Nasdaq may grant an extension of up to 180 calendar days from the date of the Notice to evidence compliance.

In order to regain compliance with the Shareholders’ Equity Requirement, we are offering the securities in this offering. We estimate (based upon assumptions we believe are reasonable) that we will have more than the required $2.5 million in shareholders’ equity as of the closing date provided we receive net proceeds of at least $3.4 million in this offering. There can be no assurance that we will be able to regain compliance with the Shareholders’ Equity Requirement, or that our common stock will remain listed on The Nasdaq Capital Market.

If our common stock is delisted from Nasdaq, it will have material negative impact on the actual and potential liquidity of our securities, as well as material negative impact on our ability to raise future capital. If, for any reason, Nasdaq should delist our common stock from trading on its exchange and we are unable to obtain listing on another national securities exchange or take action

to restore our compliance with the Nasdaq continued listing requirements, a reduction in some or all of the following may occur, each of which could have a material adverse effect on our shareholders:

Investors will experience immediate and substantial dilution as a result of this offering and may suffer substantial dilution related to issued stock warrants and options.

Investors will incur immediate and substantial dilution as a result of this offering. After giving effect to our sale in this offering of common stock, pre-funded warrants and common warrants in the aggregate amount of $8.0 million at an assumed public offering price of $2.75 per share of common stock and accompanying common warrant (assuming a public offering price equal to the last sale price of our common stock as reported by The Nasdaq Capital Market on September 15, 2025, which was $2.75 per share), and $2.749 per pre-funded warrant and accompanying common warrant (assuming a public offering price equal to the last sale price of our common stock as reported by The Nasdaq Capital Market on September 15, 2025, which was $2.75 per share), and after deducting estimated offering expenses payable by us, investors in this offering can expect an immediate dilution of $1.34 per share of common stock. See “Dilution.”

As of September 15, 2025, we have a number of agreements or obligations that may result in dilution to investors. These include:

We also have an incentive compensation plan for our management, employees and consultants. We have granted, and expect to grant in the future, options to purchase shares of our common stock to our directors, employees and consultants. To the extent that warrants or options are exercised or converted, our stockholders will experience dilution and our stock price may decrease.

Additionally, the sale, or even the possibility of the sale, of the shares of common stock underlying these warrants and options could have an adverse effect on the market price for our securities or on our ability to obtain future financing.

Our shares of common stock are thinly traded, so stockholders may be unable to sell at or near ask prices or at all if they need to sell shares to raise money or otherwise desire to liquidate their shares.

Our common stock has from time to time been “thinly-traded,” meaning that the number of persons interested in purchasing our common stock at or near ask prices at any given time may be relatively small or non-existent. This situation is attributable to a number of factors, including the fact that we are a small company that is relatively unknown to stock analysts, stock brokers, institutional investors and others in the investment community that generate or influence sales volume, and that even if we came to the attention of

such persons, they tend to be risk-averse and would be reluctant to follow an unproven company such as ours or purchase or recommend the purchase of our shares until such time as we become more seasoned and viable. As a consequence, there may be periods of several days or more when trading activity in our shares is minimal or non-existent, as compared to a seasoned issuer which has a large and steady volume of trading activity that will generally support continuous sales without an adverse effect on share price. We cannot give stockholders any assurance that a broader or more active public trading market for our common shares will develop or be sustained, or that current trading levels will be sustained.

We do not currently intend to pay dividends on our common stock in the foreseeable future, and consequently, our stockholders’ ability to achieve a return on their investment will depend on appreciation in the price of our common stock.

We have never declared or paid cash dividends on our common stock and do not anticipate paying any cash dividends to holders of our common stock in the foreseeable future. Consequently, our stockholders must rely on sales of their common stock after price appreciation, which may never occur, as the only way to realize any future gains on their investments. There is no guarantee that shares of our common stock will appreciate in value or even maintain the price at which our stockholders have purchased their shares.

Upon our dissolution, our stockholders may not recoup all or any portion of their investment.

In the event of our liquidation, dissolution or winding-up, whether voluntary or involuntary, the proceeds and/or our assets remaining after giving effect to such transaction, and the payment of all of our debts and liabilities will be distributed to the holders of common stock on a pro rata basis. There can be no assurance that we will have available assets to pay to the holders of common stock, or any amounts, upon such a liquidation, dissolution or winding-up. In this event, our stockholders could lose some or all of their investment.

The issuance of our common stock pursuant to the terms of the asset purchase agreement with Hy Biopharma Inc. may cause dilution and the issuance of such shares of common stock, or the perception that such issuances may occur, could cause the price of our common stock to fall.

On April 1, 2014, we entered into an option agreement pursuant to which Hy Biopharma Inc. (“Hy Biopharma”) granted us an option to purchase certain assets, properties and rights (the “Hypericin Assets”) related to the development of Hy Biopharma’s synthetic hypericin product candidate for the treatment of CTCL, which we refer to as HyBryte™, from Hy Biopharma. In exchange for the option, we paid $50,000 in cash and issued 18 shares of common stock in the aggregate to Hy Biopharma and its assignees. We subsequently exercised the option, and on September 3, 2014, we entered into an asset purchase agreement (the “Asset Purchase Agreement”) with Hy Biopharma, pursuant to which we purchased the Hypericin Assets. Pursuant to the Asset Purchase Agreement, we initially paid $275,000 in cash and issued 771 shares of common stock in the aggregate to Hy Biopharma and its assignees, and the licensors of the license agreement acquired from Hy Biopharma. Also, on September 3, 2014, we entered into a Registration Rights Agreement with Hy Biopharma, pursuant to which we may be required to file a registration statement with the SEC. In March 2020, we issued 8,151 shares of common stock at a value of $5,000,000 (based upon an effective per share price of $614.40 as a result of HyBryte™ demonstrating statistically significant treatment response in the Phase 3 clinical trial. We will be required to issue up to $5.0 million worth of our common stock (subject to a cap equal to 19.9% of our issued and outstanding common stock) in the aggregate, if HyBryte™ is approved for the treatment of CTCL by either the FDA or the EMA.

The number of shares that we may issue under the Asset Purchase Agreement will fluctuate based on the market price of our common stock. Depending on market liquidity at the time, the issuance of such shares may cause the trading price of our common stock to fall.

We may ultimately issue all, some or none of the additional shares of our common stock that may be issued pursuant to the Asset Purchase Agreement. We are required to register any shares issued pursuant to the Asset Purchase Agreement for resale under the Securities Act. After any such shares are registered, the holders will be able to sell all, some or none of those shares. Therefore, issuances by us under the Asset Purchase Agreement could result in substantial dilution to the interests of other holders of our common stock. Additionally, the issuance of a substantial number of shares of our common stock pursuant to the Asset Purchase Agreement, or the anticipation of such issuances, could make it more difficult for us to sell equity or equity-related securities in the future at a time and at a price that we might otherwise wish to effect sales.

Our Board of Directors can, without stockholder approval, cause preferred stock to be issued on terms that adversely affect holders of our common stock.

Under our Certificate of Incorporation, our Board of Directors is authorized to issue up to 350,000 shares of preferred stock, of which none are issued and outstanding as of the date of this prospectus. Also, our Board of Directors, without stockholder approval, may determine the price, rights, preferences, privileges and restrictions, including voting rights, of those shares. If our Board of Directors causes shares of preferred stock to be issued, the rights of the holders of our common stock would likely be subordinate to those of preferred holders and therefore could be adversely affected. Our Board of Directors’ ability to determine the terms of preferred stock and to cause its issuance, while providing desirable flexibility in connection with possible acquisitions and other corporate purposes, could have the effect of making it more difficult for a third-party to acquire a majority of our outstanding common stock. Preferred shares issued by our Board of Directors could include voting rights or super voting rights, which could shift the ability to control the Company to the holders of the preferred stock. Preferred stock could also have conversion rights into shares of our common stock at a discount to the market price of our common stock, which could negatively affect the market for our common stock. In addition, preferred stock would have preference in the event of liquidation of the Company, which means that the holders of preferred stock would be entitled to receive the net assets of the Company distributed in liquidation before the holders of our common stock receive any distribution of the liquidated assets.

Our management will have broad discretion over the use of the net proceeds from this offering and we may use the net proceeds in ways with which you disagree or which do not produce beneficial results.

We currently intend to use the net proceeds from this offering, to fund our research and development and commercialization activities, and for general corporate and working capital purposes, which may include, among other things, working capital, product development and/or commercialization, acquisitions, capital expenditures, repayment of debt and other business opportunities (see “Use of Proceeds”). We have not allocated specific amounts of the net proceeds from this offering for any of the foregoing purposes. Accordingly, our management will have significant discretion and flexibility in applying the net proceeds of this offering. You will be relying on the judgment of our management with regard to the use of these net proceeds, and you will not have the opportunity, as part of your investment decision, to assess whether the proceeds are being used appropriately. It is possible that the net proceeds will be invested in a way that does not yield a favorable, or any, return for us or our stockholders. The failure of our management to use such funds effectively could have a material adverse effect on our business, financial condition, and results of operation.

This is a best efforts offering; no minimum amount of securities is required to be sold, and we may not raise the amount of capital we believe is required for our business.

The Placement Agent has agreed to use its reasonable best efforts to solicit offers to purchase the securities in this offering. The Placement Agent has no obligation to buy any of the securities from us or to arrange for the purchase or sale of any specific number or dollar amount of the securities. There is no required minimum number of securities that must be sold as a condition to completion of this offering. Because there is no minimum offering amount required as a condition to the closing of this offering, the actual offering amount, Placement Agent fees and proceeds to us are not presently determinable and may be substantially less than the maximum amounts set forth in this prospectus. We may sell fewer than all of the securities offered hereby, which may significantly reduce the amount of proceeds received by us, and investors in this offering will not receive a refund in the event that we do not sell an amount of securities sufficient to pursue the business goals outlined in this prospectus. Thus, we may not raise the amount of capital we believe is required for our business and may need to raise additional funds, which may not be available or available on terms acceptable to us. Despite this, any proceeds from the sale of securities offered by us will be available for our immediate use, and because there is no escrow account and no minimum offering amount in this offering, investors could be in a position where they have invested in us, but we are unable to fulfill our objectives due to a lack of interest in this offering.

There is no public market for the pre-funded warrants and common warrants being offered in this offering.

There is no established public trading market for the pre-funded warrants or common warrants being offered in this offering, and we do not expect a market to develop. In addition, we do not intend to apply to list the warrants on any securities exchange or nationally recognized trading system. Without an active market, the liquidity of the pre-funded warrants and common warrants will be extremely limited.

The warrants offered by this prospectus may not have any value.

The common warrants have an assumed exercise price of $2.75 per share (assuming an exercise price equal to the last reported sale price of our common stock on The Nasdaq Capital Market on September 15, 2025, which was $2.75 per share) and will have a five-year term. In the event our common stock price does not exceed the exercise price of the common warrants during the period when the warrants are exercisable, the common warrants may not have any value.

If we do not maintain a current and effective registration statement relating to the common stock issuable upon exercise of the pre-funded warrants and common warrants being offered in this offering, holders will be able to exercise such warrants on a “cashless” basis and we may not receive any additional funds upon the exercise of such warrants.

If we do not maintain a current and effective registration statement relating to the common stock issuable upon exercise of the pre-funded warrants and common warrants being offered in this offering, such warrants may be exercised by way of a “cashless” exercise, meaning that the holder would not pay a cash purchase price upon exercise, but instead would receive upon such exercise the net number of shares of our common stock determined according to the formula set forth in the warrant. Accordingly, we may not receive any additional funds upon the exercise of such warrants.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS AND INDUSTRY DATA AND MARKET INFORMATION

This prospectus contains forward-looking statements within the meaning of Section 27A of the Securities Act, and Section 21E of the Exchange Act. These forward-looking statements are often identified by words such as “may,” “should,” “would,” “expect,” “intend,” “anticipate,” “believe,” “estimate,” “continue,” “plan,” “potential” and similar expressions. These statements involve estimates, assumptions and uncertainties that could cause actual results to differ materially from those expressed for the reasons described in this prospectus. You should not place undue reliance on these forward-looking statements.

You should be aware that our actual results could differ materially from those contained in the forward- looking statements due to a number of factors, including:

You should also consider carefully the statements under the section titled “Risk Factors” in this prospectus, which address additional factors that could cause our actual results to differ from those set forth in the forward-looking statements and could materially and adversely affect our business, operating results and financial condition. All subsequent written and oral forward-looking statements attributable to us or persons acting on our behalf are expressly qualified in their entirety by the applicable cautionary statements.

The forward-looking statements speak only as of the date on which they are made, and, except to the extent required by federal securities laws, we undertake no obligation to update any forward-looking statement to reflect events or circumstances after the date on which the statement is made or to reflect the occurrence of unanticipated events. In addition, we cannot assess the impact of each factor on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements.

Industry Data and Market Information

This prospectus contains estimates, projections and other statistical data made by independent parties and by us relating to market size and growth, the potential value of government procurement contracts, the incidence of certain medical conditions and other industry data. These data, to the extent they contain estimates or projections, involve a number of subjective assumptions and limitations, and you are cautioned not to give undue weight to such estimates or projections. Industry publications and other reports we have obtained from independent parties generally state that the data contained in these publications or other reports have been obtained in good faith or from sources considered to be reliable, but they do not guarantee the accuracy or completeness of such data. While we believe that the data from these industry publications and other reports are generally reliable, we have not independently verified the accuracy or completeness of such data in all instances. These and other factors could cause results to differ materially from those expressed in these publications and reports.

We have provided estimates of the potential worldwide market or value of potential government procurement contracts and grants for certain of our product candidates. These estimates are based on a number of factors, including our expectation as to the number of patients with a certain medical condition that would potentially benefit from a particular product candidate, the current costs of treating patients with the targeted medical condition, our expectation that we will be able to demonstrate to the FDA’s satisfaction in our clinical trials that the product candidate is safe and effective, our belief that our product candidate would, if approved, have an assumed treatment cost per patient, historic values of government procurement contracts for vaccines, and our expectation of the dosage of the product candidate. While we have determined these estimates based on assumptions that we believe are reasonable, there are a number of factors that could cause our expectations to change or not be realized. Among these factors are the following: (1) there is no assurance that the product candidate will prove to be safe and effective or will ultimately be approved for sale by the FDA; (2) any FDA approval of the product candidate may contain restrictions on its use or require warning labels; (3) third-party payors may not be willing to provide reimbursement for the product candidate at the assumed price per patient; (4) the government may not be willing to procure our vaccine candidates in amounts or at costs similar to its historic procurement activities; (5) the dosage that ultimately may be approved may be different from the assumed dosage; and (6) doctors may not adopt the product candidate for use as quickly or as broadly as we have assumed. It is possible that the ultimate market for a product candidate or value of procurement contracts will differ significantly from our expectations due to these or other factors. As a result of these and other factors, investors should not place undue reliance on such estimates.

​

USE OF PROCEEDS

We estimate that net proceeds from this offering will be approximately $7.3 million (assuming the sale of the maximum number of securities offered hereby), based upon an assumed public offering price of $2.75 per share and accompanying common warrant (which is the last reported sale price of our common stock on the Nasdaq Capital Market on September 15, 2025), and $2.749 per pre-funded warrant and accompanying common warrant (assuming a public offering price equal to the last sale price of our common stock as reported by The Nasdaq Capital Market on September 15, 2025, which was $2.75 per share), after deducting estimated Placement Agent fees and estimated offering expenses payable by us, and assuming no sale of any pre-funded warrants in this offering. However, because this is a reasonable best efforts offering with no minimum number of securities or amount of proceeds as a condition to closing, the actual offering amount, placement agent fees, and net proceeds to us are not presently determinable and may be substantially less than the maximum amounts set forth on the cover page of this prospectus, and we may not sell all or any of the securities we are offering. As a result, we may receive significantly less in net proceeds. Based on the assumed offering price set forth above, we estimate that our net proceeds from the sale of 75%, 50%, and 25% of the securities offered in this offering would be approximately $5,300,000, $3,300,000, and $1,300,000, respectively, after deducting the estimated placement agent fees and estimated offering expenses payable by us, and assuming no issuance of any pre-funded warrants and assuming no exercise of the common warrants. We will only receive additional proceeds from the exercise of the common warrants we are selling in this offering if the common warrants are exercised for cash. We cannot predict when or if these common warrants will be exercised. It is possible that these common warrants may expire and may never be exercised.

Each $0.25 increase (decrease) in the assumed public offering price of $2.75 per share and accompanying common warrant (which is the last reported sale price of our common stock on the Nasdaq Capital Market on September 15, 2025), and $2.749 per pre-funded warrant and accompanying common warrant (assuming a public offering price equal to the last sale price of our common stock as reported by The Nasdaq Capital Market on September 15, 2025, which was $2.75 per share), would increase (decrease) the net proceeds to us from this offering by $679,997, assuming the number of securities offered, as set forth on the cover page of this prospectus, remains the same, and after deducting estimated offering expenses payable by us and assuming no exercise of the common warrants or pre-funded warrants. Each 100,000 share increase (decrease) in the number of securities offered by us in this offering would increase (decrease) the net proceeds to us from this offering by $257,123, assuming that the price per share and accompanying common warrant, and per pre-funded warrant and accompanying common warrant for the offering remains at $2.75 (which is the last reported sale price of our common stock on The Nasdaq Capital Market on September 15, 2025), and after deducting the estimated offering expenses payable by us and assuming no exercise of the common warrants or pre-funded warrants included in the securities in the offering.

These estimates exclude the proceeds, if any, from the exercise of common warrants offered hereby. If all of the common warrants offered hereby were to be exercised in cash at the assumed exercise price of $2.75 per share (assuming an exercise price equal to the last reported sale price of our common stock on The Nasdaq Capital Market on September 15, 2025, which was $2.75 per share), we would receive additional gross proceeds of approximately $12 million. We cannot predict when or if these common warrants will be exercised. It is possible that these common warrants may expire and may never be exercised. Additionally, these common warrants contain a cashless exercise provision that permit exercise of such warrants on a cashless basis at any time when there is no effective registration statement under the Securities Act covering the issuance of the underlying shares.

We intend to use the net proceeds from the sale of the securities offered by us pursuant to this prospectus, if any, to fund our research and development and commercialization activities, and for general corporate and working capital purposes, which may include, among other things, working capital, product development and/or commercialization, acquisitions, capital expenditures, repayment of debt and other business opportunities. We have not determined the amount of net proceeds to be used specifically for such purposes and, as a result, management will retain broad discretion over the allocation of net proceeds. The occurrence of unforeseen events or changed business conditions could result in the application of the net proceeds from this offering in a manner other than as described in this prospectus. Pending their uses, we intend to invest the net proceeds of this offering in interest-bearing bank accounts or in short-term, interest-bearing, investment-grade securities.

DIVIDEND POLICY

We have not paid cash dividends on our common stock, and we do not anticipate that we will declare or pay dividends on our common stock in the foreseeable future. Payment of dividends, if any, is within the sole discretion of our Board of Directors and will depend, among other factors, upon our earnings, capital requirements and our operating and financial condition. To the extent we have any earnings, we likely will retain earnings to pay down debt, or expand corporate operations and not use such earnings to pay dividends.

Equity Compensation Plan Information

In December 2005, our Board of Directors approved the 2005 Equity Incentive Plan (the “2005 Plan”), which was approved by stockholders on December 29, 2005. Our 2005 Plan expired in 2015 and thus no securities remain available for future issuance under that plan.

In April 2015, our Board of Directors approved the 2015 Equity Incentive Plan (the “2015 Plan”), which was approved by stockholders on June 18, 2015. On September 22, 2022, the stockholders approved an amendment to the 2015 Plan to increase the maximum number of shares of common stock available for issuance under the plan from 2,000,000 to 6,000,000 shares. As of December 31, 2024, there were 5,770,122 shares available for future grants under the 2015 Plan; however, as of July 29, 2025 no future grants may be made under the 2015 Plan.

In May 2025, our Board of Directors approved the 2025 Equity Incentive Plan (the “2025 Plan”), which was approved by stockholders on June 20, 2025. A maximum of 6,000,000 shares of common stock may be initially delivered in satisfaction of awards made under the 2025 Plan. The number of shares of common stock reserved for issuance will automatically increase (i) on January 1 of each calendar year, from January 1, 2026 through January 1, 2035, by the least of (a) four percent of the total number of shares of common stock outstanding on December 31st of the preceding calendar year, (b) 1,000,000 shares, or (c) a number determined by our Board of Directors that is less than (a) or (b). As of September 15, 2025, there are 5,929,412 shares available for future grants under the 2025 Plan.

The following table sets forth certain information, as of December 31, 2024, with respect to the following compensation plans (including individual compensation arrangements) under which our equity securities are authorized for issuance:

​

CAPITALIZATION

The following table sets forth our cash and cash equivalents, total long-term liabilities and capitalization as of June 30, 2025 on:

You should read this capitalization table together with the section titled “Use of Proceeds” in this prospectus, and the section titled “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and our consolidated financial statements and the related notes included in this prospectus.

​

A $0.10 increase (decrease) in the assumed public offering price per share of common stock and common warrants of $2.75 (assuming a public offering price equal to the last reported sale price of our common stock on The Nasdaq Capital Market on September 15, 2025, which was $2.75 per share) would increase (decrease) the pro forma as adjusted amount of additional paid-in capital, total stockholders’ equity and total capitalization by $271,998 ($271,998), assuming that the number of shares of common stock offered by us, as set forth on the cover page of this prospectus, remains the same and after deducting estimated placement agent fees and estimated offering expenses payable by us and assuming no exercise of common warrants or sale of pre-funded warrants. An increase (decrease) of 1,000,000 in the number of shares of common stock and accompanying common warrants offered by us would increase (decrease) the pro forma as adjusted amount of additional paid-in capital, total stockholders’ equity and total capitalization by $2,571,248 ($2,571,248), assuming no change in the public offering price per share of common stock and accompanying common warrant, and after deducting estimated placement agent fees and estimated offering expenses payable by us.

The number of shares of common stock to be outstanding after this offering set forth in the table above is based on 3,504,950 shares of common stock outstanding on June 30, 2025, does not give effect to the shares of common stock issuable upon exercise of the pre-funded warrants and common warrants issued in this offering and excludes:

DILUTION

Purchasers of common stock, or pre-funded warrants, and accompanying common warrants in this offering will experience immediate dilution to the extent of the difference between the public offering price per share of common stock in this offering and the net tangible book value per share of common stock immediately after this offering.

Our pro forma net tangible book value as of June 30, 2025 was $2,842,891, or $1.41 per share of common stock, based upon 4,285,570 shares outstanding as of September 15, 2025, after giving effect to the issuance of 780,620 shares of common stock for approximately $1.4 million from June 30, 2025 through September 15, 2025. Pro forma net tangible book value per share is determined by dividing the net of total tangible assets, which excludes intangible assets, less total liabilities, by the aggregate number of shares of common stock outstanding as of June 30, 2025, as adjusted for the issuance of 780,620 shares for approximately $1.4 million from June 30, 2025 through September 15, 2025. After giving effect to our sale in this offering of common stock, or pre-funded warrants, and accompanying common warrants in the aggregate amount of $8.0 million at an assumed public offering price of $2.75 per share (assuming a public offering price equal to the last reported sale price of our common stock on The Nasdaq Capital Market on September 15, 2025, which was $2.75 per share) of common stock, or pre-funded warrant, and accompanying common warrant, and after deducting the estimated offering expenses of $700,000 payable by us, our pro forma net tangible book value as of June 30, 2025 would have been $10,142,891, or $0.66 per share of common stock. This represents an immediate increase in pro forma net tangible book value of $0.75 per share to our existing stockholders and an immediate dilution of $1.34 per share of common stock issued to the new investors purchasing securities in this offering. The dilution figures assume no sale of pre-funded warrants, which, if sold, would reduce the number of shares of common stock that we are offering on a one-for-one basis, and excludes the proceeds, if any, from the exercise of any pre-funded warrants or common warrants issued in this offering.

The following table illustrates this dilution on a per-share basis:

The above table excludes:

To the extent that options or warrants are exercised, new options are issued under our equity plans, or we issue additional shares of common stock in the future, there may be further dilution to investors participating in this offering. In addition, we may choose to raise additional capital because of market conditions or strategic considerations, even if we believe that we have sufficient funds for our current or future operating plans. If we raise additional capital through the sale of equity or convertible debt securities, the issuance of these securities could result in further dilution to our stockholders.

Because there is no minimum offering amount required as a condition to the closing of this offering, the dilution per share to purchasers in the offering may be more than that indicated above in the event that the actual number of shares sold, if any, is less than the maximum number of shares of our common stock we are offering.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis provides information that we believe is relevant to an assessment and understanding of our results of operations and financial condition. You should read this analysis in conjunction with our audited consolidated financial statements and related notes and our unaudited consolidated interim financial statements and their notes. This discussion and analysis contains statements of a forward-looking nature relating to future events or our future financial performance. These statements are only predictions, and actual events or results may differ materially. In evaluating such statements, you should carefully consider the various factors identified in this prospectus, which could cause actual results to differ materially from those expressed in, or implied by, any forward-looking statements, including those set forth in “Risk Factors” in this prospectus. See “Cautionary Note Regarding Forward-Looking Statements and Industry Data and Market Information.”

Our Business Overview

We are a late-stage biopharmaceutical company focused on developing and commercializing products to treat rare diseases where there is an unmet medical need. We maintain two active business segments: Specialized BioTherapeutics and Public Health Solutions.

Our Specialized BioTherapeutics business segment is developing and moving toward potential commercialization of HyBryte™ (a proposed proprietary name of SGX301 or synthetic hypericin sodium), a novel photodynamic therapy, utilizing topical synthetic hypericin activated with safe visible light for the treatment of cutaneous T-cell lymphoma (“CTCL”). With successful completion of the first Phase 3 FLASH (Fluorescent Light Activated Synthetic Hypericin) study and agreement from the European Medicines Agency (“EMA”) on the key design components of a confirmatory Phase 3 placebo-controlled study evaluating the safety and efficacy of HyBryte™ in the treatment of CTCL patients with early-stage disease, we began patient enrollment during December 2024 for the second Phase 3 study called “FLASH2” (Fluorescent Light Activated Synthetic Hypericin 2). We anticipate top-line results in the second half of 2026. Upon successful completion of the Phase 3 FLASH2 study, regulatory approval will be sought to support potential commercialization worldwide.

Development programs in this business segment also include expansion of synthetic hypericin (SGX302) into psoriasis, and our first-in-class Innate Defense Regulator (“IDR”) technology, dusquetide, for the treatment of inflammatory diseases, including oral mucositis in head and neck cancer (SGX942) and aphthous ulcers in Behçet’s Disease (“BD”) (SGX945).

Our Public Health Solutions business segment includes development programs for RiVax®, our ricin toxin vaccine candidate and SGX943, our therapeutic candidate for antibiotic resistant and emerging infectious disease and our vaccine programs targeting filoviruses (such as Marburg and Ebola) and CiVax™, our vaccine candidate for the prevention of COVID 19 (caused by SARS-CoV 2). The development of our vaccine programs incorporates the use of our proprietary heat stabilization platform technology, known as ThermoVax®. To date, this business segment has been supported with government grant and contract funding from the National Institute of Allergy and Infectious Diseases, the Biomedical Advanced Research and Development Authority, and the Defense Threat Reduction Agency.

An outline of our business strategy follows:

Critical Accounting Policies

Our management’s discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements, which have been prepared in accordance with generally accepted accounting principles in the U.S. The preparation of our financial statements and related disclosures requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, costs and expenses and the disclosure of contingent assets and liabilities. We base our estimates on historical experience, known trends and events and various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. We evaluate our estimates and assumptions on an ongoing basis. Our actual results may differ from these estimates under different assumptions or conditions.

While our significant accounting policies are described in more detail in the notes to our financial statements, we believe that the following accounting policies are those most critical to the assumptions and estimates used in the preparation of our financial statements.

Research and Development Costs

As part of the process of preparing our financial statements, we are required to estimate our accrued research and development expenses. This process involves reviewing open contract and purchase orders, communicating with our personnel to identify services that have been performed on our behalf and estimating the level of service performed and the associated costs incurred for the services when we have not yet been invoiced or otherwise notified of the actual costs. The majority of our service providers invoice us in arrears for services performed, on a pre-determined schedule or when contractual milestones are met; however, some require advance payments. We make estimates of our accrued expenses as of each balance sheet date in our financial statements based on facts and circumstances known to us at that time. Examples of estimated accrued research and development expenses include fees paid to:

We base our expenses related to preclinical studies and clinical trials on our estimates of the services received and efforts expended pursuant to quotes and contracts with multiple CROs that conduct and manage preclinical studies and clinical trials on our behalf. The financial terms of these agreements are subject to negotiation, vary from contract to contract and may result in uneven

payment flows. There may be instances in which payments made to our vendors will exceed the level of services provided and result in a prepayment of the expense. Payments under some of these contracts depend on factors such as the successful enrollment of patients and the completion of clinical trial milestones. In accruing fees, we estimate the time period over which services will be performed, enrollment of patients, number of sites active and the level of effort to be expended in each period. If the actual timing of the performance of services or the level of effort varies from our estimate, we adjust the accrual or amount of prepaid expense accordingly. Although we do not expect our estimates to be materially different from amounts actually incurred, our understanding of the status and timing of services performed relative to the actual status and timing of services performed may vary and may result in us reporting amounts that are too high or too low in any particular period. During the year ended December 31, 2024, we made adjustments to estimated accrued clinical trial expenses for completed trials of approximately $1.4 million. These adjustments resulted in decreases to research and development expenses in the accompanying consolidated statements of operations during the year ended December 31, 2024.

Use of Estimates and Assumptions

The preparation of financial statements in conformity with accounting principles generally accepted in the U.S. requires management to make estimates and assumptions such as the fair value of stock options and to accrue for clinical trials in process that affect the reported amounts in the financial statements and accompanying notes. Actual results could differ from those estimates.

Recent Accounting Pronouncements

In November 2023, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. This update enhances the segment reporting requirements by increasing transparency and providing investors with additional insights into how an entity’s Chief Operating Decision Maker (“CODM”) evaluates segment performance and allocates resources.

The standard requires public entities to disclose significant segment expenses that are regularly reviewed by the CODM and included in the reported measure of segment profit or loss. Additionally, entities must provide a reconciliation of total segment amounts to consolidated financial statements, as well as enhanced qualitative disclosures regarding the methodology used to identify reportable segments and assess performance. The update applies to all public entities, including those with a single reportable segment, and expands segment disclosures in interim financial statements.

ASU 2023-07 is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. We have adopted ASU 2023-07 for the year ended December 31, 2024, and have updated our segment disclosures accordingly. The adoption of this standard did not impact the recognition or measurement of our financial statements but resulted in enhanced segment- related disclosures in the notes to the consolidated financial statements.

Changes in Results of Operations

Three and Six Months Ended June 30, 2025 Compared to June 30, 2024

For the three months ended June 30, 2025, we had a net loss of $2,701,976 as compared to a net loss of $1,644,502 for the same prior year period, representing increased net loss of $1,057,474. This increase in net loss was primarily due to an increase in operating expenses related to ongoing clinical trials and a decrease in other income which was attributable to the change in the fair value of debt during the three months ended June 30, 2024 with no corresponding change in fair value during the three months ended June 30, 2025. For the six months ended June 30, 2025, we had a net loss of $5,653,244 as compared to a net loss of $3,559,829 for the same prior year period, representing increased net loss of $2,093,415. This increase in net loss was primarily due to an increase in operating expenses related to ongoing clinical trials and a decrease in other income which was attributable to the change in the fair value of debt during the six months ended June 30, 2024 with no corresponding change in fair value during the six months ended June 30, 2025.

Our revenues and associated costs incurred related to government subawards received to support the evaluation of HyBryte™ for expanded treatment in patients with early-stage CTCL. For the three months ended June 30, 2025, we had no revenue as compared to revenue of $2,342 for the same prior year period, representing a decrease in revenue of $2,342. We also incurred costs related to those revenues for the three months ended June 30, 2024 of $2,342. For the six months ended June 30, 2025, we had no revenue as compared to revenue of $119,371 for the same prior year period, representing a decrease in revenue of $119,371. We also incurred costs related to those revenues for the six months ended June 30, 2024 of $119,371.

Research and development expenses were $1,677,014 for the three months ended June 30, 2025 as compared to $501,158 for the same period in 2024, representing an increase of $1,175,856. The increase was primarily due to costs associated with our Phase 2 study in BD and the second confirmatory Phase 3 CTCL trial as well as increases in third-party manufacturing. Research and development expenses were $3,618,694 for the six months ended June 30, 2025 as compared to $1,596,198 for the same period in 2024, representing an increase of $2,022,496. The increase was primarily due to costs associated with our Phase 2 study in BD and the second confirmatory Phase 3 CTCL trial as well as increases in third-party manufacturing.

General and administrative expenses were $1,086,865 for the three months ended June 30, 2025, as compared to $1,243,517 for the same period in 2024, representing a decrease of $156,652. The decrease in general and administrative expenses for the three months ended June 30, 2025 was primarily attributable to decreases in professional fees offset by increases in various taxes. General and administrative expenses were $2,171,693 for the six months ended June 30, 2025, as compared to $2,265,568 for the same period in 2024, representing a decrease of $93,875. The decrease in general and administrative expenses for the six months ended June 30, 2025 was primarily attributable to decreases in professional fees offset by increases in various taxes.

Interest income, net for the three months ended June 30, 2025 was $69,823 as compared to $35,925 for the same period in 2024, representing an increase of $33,898. The increase is primarily associated with a reduction in interest expense resulting from repayment of convertible debt. Interest income, net for the six months ended June 30, 2025 was $145,851 as compared to $64,767 for the same period in 2024, representing an increase of $81,084. The increase is primarily associated with a reduction in interest expense resulting from repayment of convertible debt.

Year Ended December 31, 2024 Compared to December 31, 2023

For the year ended December 31, 2024, we had a net loss of $8,266,576 as compared to a net loss of $6,140,730 for the prior year, representing increased net loss of $2,125,846 or 35%. The increase in net loss is primarily attributed to decreases in gross profit and income tax benefits as well as an increase in operating expenses, offset by increases in interest income, tax credits and the change in the fair value of debt. For the year ended December 31, 2024, we had revenues of $119,371 as compared to $839,359 for the prior year, representing a decrease of $719,988 or 86%. The decrease in revenues was primarily a result of the conclusion of higher margin grants associated with the development of SGX943 and CiVax™ and a decrease in revenue associated with the zero margin grant for the HyBryte™ investigator initiated study.

We incurred costs related to contract and grant revenues in the year ended December 31, 2024 and 2023 of $119,371 and $742,048, respectively, representing a decrease of $622,677 or 84%. The decrease in costs was primarily the result of the conclusion of higher margin grants associated with the development of SGX943 and CiVax™ and a decrease in the zero margin grant for the HyBryte™ investigator initiated study.

Our gross profit for the year ended December 31, 2024 was $0 or 0% of total revenues as compared to $97,311 or 12% of total revenues for the prior year, representing a decrease of $97,311 or 100%. The decrease in gross profit was primarily the result of the conclusion of higher margin grants associated with the development of SGX943 and CiVax™ and a decrease in the zero margin grant for the HyBryte™ investigator initiated study.

Research and development expenses increased by $1,910,890 or 58% to $5,223,589 for year ended December 31, 2024 as compared to $3,312,699 for the prior year. The increase in research and development spending for the year ended December 31, 2024 was primarily related to preliminary costs associated with the initiation of our Phase 2 study in BD and the second confirmatory Phase 3 CTCL trial offset by an adjustment of estimated accruals for completed clinical trials.

General and administrative expenses decreased by $266,644 or 6%, to $4,215,908 for the year ended December 31, 2024, as compared to $4,482,552 for the prior year. This decrease is primarily related to a reduction in legal and consulting expenses.

In April 2023, we entered into an amendment (the “2023 Amendment”) to the convertible debt financing agreement with Pontifax Medison Finance (“Pontifax”) (see Note 5 — Debt). The 2023 Amendment resulted in the extinguishment of the original convertible debt for accounting purposes. We elected to account for the amended convertible debt using the fair value option, which requires us to record changes in fair value as a component of other income or expense. The fair value of the convertible debt on the date of the amendment was approximately $3,304,000, which resulted in the recognition of a loss on extinguishment of approximately $394,000 on our accompanying consolidated statements of operations during the year ended December 31, 2023. The fair value of the convertible debt as of December 31, 2023 was approximately $3,260,934, which resulted in the recognition of $43,066 of other

income from the change in the fair value of the convertible debt on our accompanying consolidated statements of operations for the year ended December 31, 2023. For 2023 and through the 2024 Amendment (described below), the fair value of the convertible debt was estimated using the Monte Carlo valuation method.

In October 2024, we entered into an amendment (the “2024 Amendment”) to the convertible debt financing agreement with Pontifax, as amended. The 2024 Amendment resulted in a substantial modification of the debt for accounting purposes, as defined, which is accounted for as an extinguishment. The difference between the fair value, or net carrying amount, of the debt before the 2024 Amendment and upon reacquisition was de minimus. Accordingly, no gain or loss was recognized related to the extinguishment related to the 2024 Amendment. Furthermore, as the 2024 Amendment resulted in a substantial modification, as defined, we elected not to account for the convertible debt using the fair value option in accordance with the applicable guidance. We determined the embedded conversion feature, after the 2024 Amendment, does not require bifurcation and therefore the convertible debt, as amended, has been recorded as a single liability classified instrument in accordance with ASU 2020-06. As a result of this election, we recognized a gain of $260,933 of other income from the change in the fair value of the convertible debt on our accompanying 2024 consolidated statement of operations.

Total other income for the year ended December 31, 2024 was $763,807 as compared to $210,593 of total other expense for the prior year, reflecting a decrease of $974,400 or 463%. The decrease in total other expense was primarily associated with the reduction in interest resulting from the repayment of a portion of the convertible debt principal balance, higher interest income earned on cash balances, an increase in tax credits, an increase in other income resulting from the change in the fair value of the convertible debt and approximately $394,000 of a loss on extinguishment of debt resulting from an amendment to the original convertible debt loan agreement was recognized in 2023.

The State of New Jersey’s Technology Business Tax Certificate Program allows certain high technology and biotechnology companies to sell unused NOL carryforwards to other New Jersey-based corporate taxpayers. We sold 2023, 2022 and 2021 New Jersey NOL carryforwards resulting in the recognition of income tax benefits, net of transaction costs of $409,114 and $1,767,803 during the years ended December 31, 2024 and 2023, respectively. We sold our 2023 New Jersey NOLs and have recorded a receivable of $409,114 which is included in prepaid expenses and other current assets on the accompanying consolidated balance sheet for the year ended December 31, 2024. We have not yet sold our 2024 New Jersey NOL carryforwards but may do so in the future. We will continue to explore opportunities to sell unused NOL carryforwards for the year ended December 31, 2024. However, there can be no assurance as to the continuation or magnitude of this program in future years.

Business Segments

We maintain two active business segments for the years ended December 31, 2024 and 2023: Specialized BioTherapeutics and Public Health Solutions.

The Specialized BioTherapeutics business segment had revenue of $119,371 for the year ended December 31, 2024 as compared to $395,124 for the year ended December 31, 2023, representing a decrease of $275,753 or 70%. The decrease was due to decreased reimbursable development activity under the grant to support the investigator-initiated study of HyBryte™ for expanded treatment in patients with early-stage CTCL.

Revenues for the Public Health Solutions business segment for the year ended December 31, 2024 were $0 as compared to $444,235 for the year ended December 31, 2023, representing a decrease of $444,235 or 100%. The decrease in revenues was primarily the result of the conclusion of the grant associated with the development of SGX943.

Loss from operations for the Public Health Solutions business segment for the year ended December 31, 2024 was $254,576 as compared to loss from operations of $36,531 for the year ended December 31, 2023, representing an increase in loss of $218,045 or 597%. The loss for the year ended December 31, 2024 is attributable to additional expenses incurred due to the expiration of grants and contracts. Loss from operations for the Specialized BioTherapeutics business segment for the year ended December 31, 2024 was $4,365,034 as compared to $2,812,303 for the year ended December 31, 2023, representing an increase in loss of $1,552,731 or 55%. This increase in loss is primarily related to preliminary costs associated with the initiation of our Phase 2 study in BD and the second confirmatory Phase 3 CTCL trial offset by an adjustment of estimated accruals for completed clinical trials.

Financial Condition and Liquidity

Cash and Working Capital

As of June 30, 2025, we had cash and cash equivalents of $5,097,670 as compared to $7,819,514 as of December 31, 2024, representing a decrease of $2,721,844. As of June 30, 2025, we had working capital of $1,691,345 as compared to working capital of $3,980,218 as of December 31, 2024, representing a decrease of $2,288,873. The decrease in cash and cash equivalents was primarily related to cash used in operating activities and repayment of convertible debt offset by cash received from financing activities during the six months ended June 30, 2025.

Based on our operating budget, current rate of cash outflows, cash on hand, and proceeds from government contract and grant programs, we believe that we have sufficient resources to support development activities, business operations, and meet our obligations through the first quarter of 2026. However, as of the date of issuance of the financial statements for the fiscal quarter ended June 30, 2025 that are included in this prospectus, we did not have sufficient cash and cash equivalents to fund operations for at least 12 months following such date. These factors raise substantial doubt about our ability to continue as a going concern.

To alleviate the conditions that raise substantial doubt about our ability to continue as a going concern, our plans, as of June 30, 2025, include securing:

There is no assurance that we will be successful in securing sufficient financing on acceptable terms, if at all, to continue operations, enter into strategic transactions that provide the necessary capital, or implement other strategies to mitigate the substantial doubt about our ability to continue as a going concern. If these alternatives are unavailable or not secured on satisfactory terms, we will not have sufficient cash resources or liquidity to fund our operations for at least 12 months after the date of issuance of the financial statements for the fiscal quarter ended June 30, 2025 that are included in this prospectus. Failure to obtain adequate capital when needed may force us to delay, reduce, or eliminate business development efforts, negatively impacting our ability to achieve our objectives, remain competitive, and maintain our financial condition and operating results. On July 1, 2025, we sold 772,900 shares of common stock pursuant to our ATM facility for total gross proceeds of approximately $1,429,100 and in doing so, as of July 1, 2025, we have no further capacity on the ATM facility.

Additionally, macroeconomic and geopolitical uncertainties may further restrict access to capital, exacerbating liquidity challenges. Furthermore, concerns regarding our ability to continue as a going concern could negatively impact relationships with business partners, vendors, and other stakeholders.

The accompanying financial statements have been prepared on a going concern basis, which contemplates the realization of assets and satisfaction of liabilities in the normal course of business, and do not include any adjustments relating to recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might be necessary should we be unable to continue as a going concern.

Our plans with respect to our liquidity management include, but are not limited to, the following:

Research and Development Expenditures

Under our budget and based upon our existing product development agreements and license agreements, we expect our total research and development expenditures for the next 12 months to be approximately $4.8 million before any contract or grant reimbursements, all of which relates to the Specialized BioTherapeutics business segment. We do not anticipate any contract and grant reimbursements revenue in the next 12 months to offset research and development expenses in the Specialized BioTherapeutics business segment.
