Current report

The FDA’s shift toward “radical transparency,” including plans to release future complete response letters promptly after they are issued to sponsors, could have an adverse impact on our business and adversely affect our commercial prospects.

Current report

In July 2025, the FDA announced a policy shift toward public disclosure of complete response letters issued for drugs that had not been approved. Additionally, in September 2025, the FDA announced that it will release future complete response letters promptly after they are issued to sponsors and the agency released a number of unpublished complete response letters issued since 2024 associated with pending or withdrawn applications, including the reproxalap Complete Response Letter. Although the FDA has stated that all released letters will be redacted to remove confidential commercial information, trade secrets, and personal private information, public disclosure of any such letters we may receive could expose detailed information regarding our clinical data, chemistry, manufacturing and controls (CMC), or regulatory strategy. Although we intend to coordinate closely with the FDA to protect proprietary information, there is no assurance that such efforts will be successful or that any inadvertent disclosures will be remedied. Moreover, once published, we may have limited ability to correct or contextualize the FDA’s statements. As a result, this new policy of radical transparency could result in unforeseen reputational, operational, financial, and legal consequences for our company

Current report

Any public release of a complete response letter for one of our product candidates could materially and adversely affect our business and result in unforeseen reputational, operational, financial, and legal consequences. Such publication, among other things, may:

Current report

lead to negative publicity and loss of investor confidence in our development programs, causing significant volatility in our stock price;

Current report

damage relationships with collaborators, suppliers, and current or potential partners, some of whom may reconsider engagements or financing commitments based on perceived weaknesses in our programs;

Current report

create or amplify litigation risk, including shareholder class actions alleging violations of federal securities laws;

Current report

trigger heightened SEC scrutiny of our disclosure practices if information included in the FDA’s publication is inconsistent with prior public statements or filings; or

Current report

delay or complicate ongoing regulatory interactions, particularly if deficiencies cited by the FDA are discussed publicly before resolution.

Current report

In August 2025, the FDA notified us that it had conducted a cGMP inspection of our third-party manufacturer of reproxalap and conveyed deficiencies to the third-party manufacturer in a Form 483 letter. The third-party manufacturer developed a remediation plan and subsequently submitted the plan and progress updates to the FDA. The FDA notified the third-party manufacturer that the inspection classification of the facility was a voluntary action indicated (VAI), that the inspection has been closed, and that no further action is necessary at this time. The FDA inspection closure letter stated that an inspection classification of VAI will not negatively impact FDA's assessment of any pending marketing applications referencing the facility. Future noncompliance could result in the imposition of sanctions, including fines, injunctions, civil penalties, failure of regulatory authorities to grant marketing approvals for our product candidates, delays, suspension or withdrawal of approvals, license revocation, seizures or recalls of products, operating restrictions, and criminal prosecutions, any of which could damage our reputation or impair our ability to develop and commercialize our products. If we are not able to maintain regulatory compliance, we may not be permitted to market our products and/or may be subject to product recalls, seizures, injunctions, or criminal prosecution.

short sellers and manipulative techniques employed by short sellers to drive down the market price of our common stock;

Current report

Short sellers may be manipulative and may drive down the market price of our common shares.

Current report

Short sellers of our stock may be manipulative and may attempt to drive down the market price of shares of our common stock. Short selling is the practice of selling securities that the seller does not own but rather has borrowed from a third party with the intention of buying identical securities back at a later date to return to the lender. The short seller hopes to profit from a decline in the value of the securities between the sale of the borrowed securities and the purchase of the replacement shares, as the short seller expects to pay less in that purchase than received from the sale. Therefore, short sellers (sometime known as “disclosed shorts”) often publish, or arrange for the publication of, negative opinions regarding the relevant issuer and its business prospects to create negative market momentum and generate profits for themselves after selling a stock short. Although, in the past, disclosed shorts were not able to broadly access mainstream business media or to otherwise create negative market rumors, the rise of technological advancements regarding document creation, videotaping, and publication by blogging have allowed many disclosed shorts to publicly attack a company’s credibility, strategy, and veracity by means of so-called “research reports” that mimic the type of investment analysis performed by large Wall Street firms and independent research analysts. Short seller publications are not regulated by any governmental, self-regulatory organization, or other official authority in the United States, and are not subject to certification requirements imposed by the SEC. Accordingly, the opinions expressed by short sellers may be based on distortions or omissions of actual facts or, in some cases, fabrications of facts. Short attacks have, in the past, led to significant selling of shares in the market. Issuers who have limited trading volumes and are susceptible to higher volatility levels than large-cap stocks can be particularly vulnerable to short seller attacks. Significant short selling creates an incentive for market participants to reduce the value of the stock that is shorted. Short selling may lead to the placement of sell orders by short sellers without commensurate buy orders because the shares borrowed by short sellers do not have to be returned by any fixed period of time. If a significant market for short selling our common stock develops, the market price of our common stock could be significantly depressed.

Current report

The SEC has adopted rules that regulate broker-dealer practices in connection with transactions in penny stocks. Penny stocks are generally equity securities with a price of less than $5.00, other than securities registered on certain national securities exchanges or authorized for quotation on certain automated quotation systems, provided that current price and volume information with respect to transactions in such securities is provided by the exchange or system. If we do not retain a listing on Nasdaq and if the price of our common stock is less than $5.00, our common stock will be deemed a penny stock. The penny stock rules require a broker-dealer, before a transaction in a penny stock not otherwise exempt from those rules, to deliver a standardized risk disclosure document containing specified information. In addition, the penny stock rules require that before effecting any transaction in a penny stock not otherwise exempt from those rules, a broker-dealer must make a special written determination that the penny stock is a suitable investment for the purchaser and receive (i) the purchaser’s written acknowledgment of the receipt of a risk disclosure statement; (ii) a written agreement to transactions involving penny stocks; and (iii) a signed and dated copy of a written suitability statement. These disclosure requirements may have the effect of reducing the trading activity in the secondary market for our common stock, and therefore stockholders may have difficulty selling shares.

Previous wording

As part of our growth strategy, we plan to evaluate the development and commercialization of other therapies related to immune-mediated and metabolic diseases. We will evaluate internal opportunities from our compound libraries, and also may choose to continue to in-license or acquire other product candidates, as well as commercial products, to treat patients suffering from immune-mediated and metabolic disorders with high unmet medical needs and limited treatment options. New product candidates will require additional, time-consuming development efforts prior to commercial sale, including preclinical studies, clinical trials, and approval by the FDA and/or applicable foreign regulatory authorities. In-licensed product candidates may have been unsuccessfully developed by others in indications similar to those that we may pursue. All product candidates are prone to the risks of failure that are inherent in pharmaceutical product development, including the possibility that the product candidate will not be shown to be sufficiently safe and/or effective for approval by regulatory authorities. For example, in June 2023, we received a Complete Response Letter from the FDA regarding our NDA for ADX‑2191 for the treatment of primary vitreoretinal lymphoma (the ADX‑2191 Complete Response Letter). The ADX‑2191 Complete Response Letter stated that there was a “lack of substantial evidence of effectiveness” due to “a lack of adequate and well-controlled investigations” in the literature-based NDA submission. In January 2024 we de-prioritized the previously announced programs of ADX‑629 in chronic cough and idiopathic nephrotic syndrome due to regulatory and trial feasibility challenges, respectively. Additionally, in the year ended December 31, 2024, we deprioritized and subsequently ceased development of ADX‑2191 for the treatment of proliferative vitreoretinopathy due to the requirement from the FDA to run clinical trials that we did not deem to be feasible. If marketing approval for our other product candidates is delayed, limited or denied, our ability to market the product candidate, and our ability to generate product sales, would be adversely affected. Such a delay could occur because a competitor product is approved before our product and secures patent protection, market exclusivity, or both, and thereby precludes our product approval for a number of years. It is also possible that additional studies or clinical trials may not suffice to make our application approvable. In addition, we cannot assure you that any such products that are approved will be manufactured or produced economically, adequately priced, successfully commercialized, or widely accepted in the marketplace, or will be more effective than other commercially available alternatives.

Previous wording

The clinical development, manufacturing, labeling, storage, record-keeping, advertising, promotion, import, export, marketing, and distribution of our product candidates are subject to extensive regulation by the FDA in the United States and by comparable authorities in foreign markets. In the United States, we are not permitted to market our product candidates until we receive regulatory approval from the FDA. The process of obtaining regulatory approval is expensive and time-consuming, and can vary substantially based upon the type, complexity, and novelty of the products involved, as well as the target indication, and patient population. Approval policies or regulations may change, and the FDA has substantial discretion in the drug approval process, including the ability to delay, limit, or deny approval of a product candidate for many reasons. Despite the time and expense invested in clinical development of product candidates, regulatory approval, and subsequent commercial success is uncertain and not guaranteed.

Additionally, other parties have and may file citizens' petitions with the FDA in an attempt to persuade the FDA that our product candidates, or the clinical trials that support our product candidates contain deficiencies. Such actions could delay or even prevent the FDA from approving any of our NDAs. Despite the time and expense invested in clinical development of product candidates, regulatory approval, and subsequent commercial success is uncertain and not guaranteed.

Previous wording

Our clinical focus is on the development of new products for immune-mediated and metabolic diseases. We performed an adaptive trial in proliferative vitreoretinopathy, the GUARD trial, and may do so with other indications in the future. In an adaptive trial, the initial parts of the trial are not designed to be pivotal or definitive. Rather, the initial parts of adaptive trials are expected to provide data to guide subsequent parts of the trial, which could require design changes, including but not limited to, different endpoints. In addition, following the initial parts of adaptive trials, we may, among other things, decide to continue to the subsequent parts of the trial, conclude the trial based on the success or failure in such initial parts, or discuss the trial results and regulatory pathway with regulatory authorities prior to determining next steps with respect to the trial and development program. As such, the likelihood of success in our late-stage clinical programs cannot necessarily be predicted.

We could also face challenges in designing clinical trials and obtaining regulatory approval of our product candidates due to the lack of historical clinical trial experience for novel classes of therapeutics. Thus, it is difficult to determine whether regulatory agencies will be receptive to the approval of our product candidates, and to predict the time and costs associated with obtaining regulatory approvals. The clinical trial requirements of the FDA and other regulatory agencies and the criteria regulators use to determine the safety and efficacy of a product candidate vary substantially according to the type, complexity, novelty, and intended use and market of the potential products. The regulatory approval process for novel product candidates such as ours can be more expensive and require more time and trial data than for other, better known, or more extensively studied classes of product candidates.

In addition, it is possible that, as regulatory bodies gain more familiarity with our type of product candidates by reviewing competitor candidates, those agencies could impose new conditions on our product candidates that we did not expect. Any inability to design clinical trials with protocols, methodology, and endpoints acceptable to applicable regulatory authorities, and to obtain regulatory approvals for our product candidates, would have an adverse impact on our business, prospects, financial condition, and results of operations.

Previous wording

There exist several designations that we can apply for from the FDA and other regulators, including the European Medicines Agency (EMA), that would provide us with various combinations of the potential for expedited regulatory review, certain financial incentives as well as the potential for post-approval exclusivity for a period of time. FDA designations include but are not limited to orphan drug designation, breakthrough therapy designation, accelerated approval, fast track status, and priority review for our product candidates. We may seek one or more of these designations for our current and future product candidates. For example, ADX‑2191 has received orphan designation from the FDA for the treatment of primary vitreoretinal lymphoma and retinitis pigmentosa, as well as orphan designation from the EMA for the treatment of inherited retinal dystrophies of the rod-dominant phenotype, including retinitis pigmentosa. There can be no assurance that any of our other product candidates will qualify for any of these designations. There can also be no assurance that any of our product candidates that do qualify for FDA or EMA designations will be granted such designations or that the FDA or EMA will not revoke such a designation. Further, there can be no assurance that any of our product candidates that are granted such designations will ever benefit from such designations or that the FDA or EMA would not withdraw such designations once granted. Were we to receive a designation that promised a period of market exclusivity, such as orphan drug exclusivity, such exclusivity may not effectively protect the product from competition because different drugs can be approved for the same condition. Further, with respect to orphan drug status, even after an orphan drug is approved, the FDA or EMA can subsequently approve the same drug for the same condition if the FDA or EMA concludes that the later drug is clinically superior if it is shown to be safer, more effective, or makes a major contribution to patient care.

As part of our business strategy, we have and continue to evaluate the development and commercialization of product candidates for the treatment of orphan and other rare diseases, including Sjögren-Larsson and retinitis pigmentosa. We may not be able to initiate or continue clinical trials if we are unable to locate a sufficient number of eligible patients willing and able to participate in the clinical trials required by the FDA or other non-United States regulatory agencies. In addition, if others develop products for the treatment of similar diseases, we would potentially compete for the enrollment in rare patient populations, which may adversely impact the rate of patient enrollment in and the timely completion of our current and planned clinical trials. Any negative results or perceived negative results in clinical trials of our product candidates may make it difficult or impossible to recruit or retain patients in other clinical trials of the same product candidate. Insufficient patient enrollment may be a function of other factors, including the size and nature of the patient population, the nature of the protocol, the proximity of patients to clinical sites, the timing and magnitude of disease symptom presentation, the availability of effective treatments for the relevant disease, and the eligibility criteria for the clinical trial. Our inability to identify and enroll a sufficient number of eligible patients for any of our current or future clinical trials would result in significant delays or may require us to abandon one or more clinical trials or development program. Public health epidemics or pandemics and the response thereto may have an impact on our ability to enroll and retain patients in our clinical trials. For instance, patient enrollment in our GUARD trial of ADX‑2191 in proliferative vitreoretinopathy was negatively impacted as a result of limited clinical trial staffing at trial sites and some patients electing to delay surgery. Delays in patient enrollment in the future as a result of these and other factors may result in increased costs or may affect the timing or outcome of our clinical trials, which could prevent us from completing these trials and adversely affect our ability to advance the development of our product candidates. For instance, in rare diseases such as proliferative vitreoretinopathy and idiopathic nephrotic syndrome, lack of availability of, or difficulty recruiting or retaining a sufficient number of, patients may make it difficult or cost-prohibitive to sufficiently power our clinical trials, which may not enable us to continue development and seek regulatory approval for the applicable product candidate. Further, if our products are approved by regulatory agencies, we may not be able to identify sufficient number of patients to generate significant revenue.

We focus our research and product development on treatments for immune-mediated and metabolic diseases. Our estimated addressable markets and market opportunities for our product candidates are based on a variety of inputs, including data published by third parties, our own market insights and internal market intelligence, and internally generated data and assumptions. We have not independently verified any third-party information and cannot be assured of its accuracy or completeness. Our projections of both the number of people who have diseases in our target markets, as well as the subset of people with diseases who have the potential to benefit from treatment with our product candidates, are based on estimates that have been derived from a variety of sources, including scientific literature, surveys of clinics, or market research, and may prove to be incorrect. Further, new studies may change the estimated incidence or prevalence of diseases in our target markets. The number of patients may turn out to be lower or more difficult to identify than expected. In addition, our product candidates may not achieve commercial success due to market conditions or regulatory challenges.

We and our contract manufacturers must comply with the cGMP regulations and guidelines. We and our contract manufacturers may encounter difficulties in achieving quality control and quality assurance and may experience shortages in qualified personnel. We and our contract manufacturers are subject to inspections by the FDA and comparable agencies in other jurisdictions to confirm compliance with applicable regulatory requirements. Any failure to follow cGMP or other regulatory requirements or any delay, interruption, or other issues that arise in the manufacture, fill-finish, packaging, or storage of our products as a result of a failure of our facilities or the facilities or operations of third parties to comply with regulatory requirements or pass any regulatory authority inspection could significantly impair our ability to develop and commercialize our products, including leading to significant delays in the availability of products for our clinical trials, the termination or hold on a clinical trial, or the delay or prevention of a filing or approval of marketing applications for our product candidates. Significant noncompliance could also result in the imposition of sanctions, including fines, injunctions, civil penalties, failure of regulatory authorities to grant marketing approvals for our product candidates, delays, suspension or withdrawal of approvals, license revocation, seizures or recalls of products, operating restrictions, and criminal prosecutions, any of which could damage our reputation or impair our ability to develop and commercialize our products. If we are not able to maintain regulatory compliance, we may not be permitted to market our products and/or may be subject to product recalls, seizures, injunctions, or criminal prosecution.

Current wording

Any failure to follow cGMP or other regulatory requirements or any delay, interruption, or other issues that arise in the manufacture, fill-finish, packaging, or storage of our products as a result of a failure of our facilities or the facilities or operations of third parties to comply with regulatory requirements or pass any regulatory authority inspection could significantly impair our ability to develop and commercialize our products, including leading to significant delays in the availability of products for our clinical trials, the termination or hold on a clinical trial, or the delay or prevention of a filing or approval of marketing applications for our product candidates. Our reliance on third-party manufacturing facilities located outside the United States exposes us to significant regulatory and operational risks. The FDA has recently expanded its use of unannounced inspections of foreign manufacturing sites, and any failure by these facilities to comply with applicable cGMP or inspection requirements could result in product shipment delays, warning letters, import restrictions, or the loss of manufacturing authorization. In addition, ongoing political pressures to strengthen oversight of foreign drug and medical supply chains may lead to stricter enforcement and increased inspection frequency. Furthermore, the current presidential administration has issued executive orders aimed at encouraging the return of pharmaceutical manufacturing to the United States, which could result in additional FDA scrutiny of foreign facilities and create further operational uncertainty for overseas manufacturers. These developments could disrupt our supply chain, increase costs, and adversely affect our ability to manufacture and distribute products on time and in compliance with U.S. regulatory standards.

We operate in highly competitive segments of the biotechnology market. We face competition from many different sources, including commercial pharmaceutical and biotechnology enterprises, academic institutions, government agencies, and private and public research institutions. Our product candidates, if successfully developed and approved, will compete with established therapies (including generic and over-the-counter drugs) as well as with new treatments that may be introduced by our competitors. With the exception of proliferative vitreoretinopathy and retinitis pigmentosa, there are a variety of approved drugs and drug candidates in development for the indications that we intend to test. Current pharmaceutical treatments that are used in the United States for dry eye disease include over the counter artificial tears, Restasis®, Xiidra®, Cequa®, Eysuvis®, Tyrvaya®, Miebo TM, and Vevye®. In February 2022, the FDA approved the first generic version of Restasis®, which is now available for sale in the U.S. Many of our competitors have significantly greater financial, product candidate development, manufacturing, and marketing resources than we do. Large pharmaceutical and biotechnology companies have extensive experience in clinical testing and obtaining regulatory approval for drugs. In addition, universities and private and public research institutes could be in direct competition with us. We also may compete with these organizations to recruit management, scientists, and commercial and clinical development personnel. We will also face competition from these third parties in establishing clinical trial sites, registering subjects for clinical trials, and identifying and in-licensing new product candidates. Smaller or early-stage companies may also prove to be significant competitors, particularly through collaborative arrangements with large and established companies.

Current wording

We operate in highly competitive segments of the biotechnology market. We face competition from many different sources, including commercial pharmaceutical and biotechnology enterprises, academic institutions, government agencies, and private and public research institutions. Our product candidates, if successfully developed and approved, will compete with established therapies (including generic and over-the-counter drugs) as well as with new treatments that may be introduced by our competitors. With the exception of primary vitreoretinal lymphoma and retinitis pigmentosa, there are a variety of approved drugs and drug candidates in development for the indications that we intend to test. Current pharmaceutical treatments that are used in the United States for dry eye disease include over the counter artificial tears, Restasis®, Xiidra®, Cequa®, Eysuvis®, Tyrvaya®, Miebo TM, Vevye®, and TRYPTYRTM. In February 2022, the FDA approved the first generic version of Restasis®, which is now available for sale in the U.S. Many of our competitors have significantly greater financial, product candidate development, manufacturing, and marketing resources than we do. Large pharmaceutical and biotechnology companies have extensive experience in clinical testing and obtaining regulatory approval for drugs. In addition, universities and private and public research institutes could be in direct competition with us. We also may compete with these organizations to recruit management, scientists, and commercial and clinical development personnel. We will also face competition from these third parties in establishing clinical trial sites, registering subjects for clinical trials, and identifying and in-licensing new product candidates.

Previous wording

Disruptions at the FDA and other governmental agencies may also slow the time necessary for new drugs to be reviewed and/or approved by necessary government agencies, which would adversely affect our operating results and 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 employees from the FDA, SEC, and other government offices, halting critical activities. If a prolonged government shutdown occurs, it could significantly impact the FDA's ability to review and process our regulatory submissions in a timely manner, which could have a material adverse effect on our business. Furthermore, in our operations as a public company, future government shutdowns could impact our ability to access the public markets and obtain necessary capital in order to properly capitalize and continue our operations.

The U.S. federal government has been shut down since October 1, 2025. During the shutdown, the FDA has operated on a reduced basis with many non-essential functions suspended. While reviews tied to already paid user fees are continuing, companies may experience slower communications and selective deferrals. A government shutdown may prevent the FDA from conducting their regular inspections, reviews or other regulatory activities, and could significantly impact the ability of the FDA to timely review and process our regulatory submissions by the applicable PDUFA date, including our Reproxalap NDA, which could have a material adverse impact on our business. Furthermore, in our operations as a public company, government shutdowns could impact our ability to access the public markets and obtain necessary capital in order to properly capitalize and continue our operations.

We face uncertainty regarding the potential for changes in the regulatory environment following the change in presidential administration in January 2025. While many of the Trump administration's proposed policies appear to be focused on deregulation, the new administration and federal government could adopt legislation, regulation, or policy that adversely affects our business or creates a more challenging and costly environment to pursue the development and commercialization of our product candidates. For example, the federal government, including the HHS, and the FDA, may implement legislative, regulatory, or policy changes regarding the standards for approving new product candidates. Additionally, because one objective of the current Trump administration is to decrease spending in the federal government, there have been FDA staff reductions, which could impact the FDA's ability to engage in routine regulatory and oversight activities and result in delays or limitations on our ability to proceed with clinical development programs and obtain regulatory approvals. It is difficult to predict how executive actions that may be taken under the current Trump administration may affect the FDA's ability to exercise its regulatory authority. If such executive actions impose constraints on the FDA's ability to engage in routine oversight and product review activities in the normal course, our business may be negatively impacted.

We have incurred significant operating losses since we were founded in 2004 and expect to incur significant losses for the next several years as we continue our clinical trial, development programs, and commercial activities for reproxalap and our other product candidates. Net loss for the six months ended June 30, 2025 and 2024 was approximately $19.7 million and $24.9 million, respectively. As of June 30, 2025, we had total stockholders’ equity of $55.3 million and an accumulated deficit of $469.8 million. Losses have resulted principally from costs incurred in our clinical trials and research and development programs, and from general and administrative expenses. In the future, we intend to continue to conduct research and development, clinical testing, regulatory compliance activities, pre-commercial activities, and, if reproxalap or any of our other product candidates is approved and we do not enter into collaboration agreements with third parties, commercialization efforts, including sales and marketing activities, that, together with anticipated general and administrative expenses, will likely result in our incurring further significant losses for the next several years. Our net losses may fluctuate significantly from quarter to quarter and year to year.

The laws that govern our taxation, including with respect to income and non-income taxes, are unsettled and may be subject to significant change. Changes in tax laws, regulations, or rulings, or changes in interpretations of existing laws and regulations, could materially adversely affect our company. For example, the Tax Cuts and Jobs Act (TCJA), the Coronavirus Aid, Relief, and Economic Security Act (CARES), and the IRA (as defined below) enacted a number of significant changes to the U.S. tax laws. Future guidance from the IRS and other tax authorities with respect to such legislation may affect us, and certain aspects thereof could be repealed or modified in future legislation. For example, the Internal Revenue Code tax capitalization rules enacted in 2022 required research and development expenses to be capitalized and amortized over a 5-year period for tax purposes. However, The One Big Beautiful Bill Act (OBBB Act) features several tax reforms, including permitting taxpayers to permanently deduct domestic research and development expenses for amounts paid or incurred in tax years beginning after December 31, 2024. We are continuing to analyze the potential impact of the OBBB Act on our operations and financial condition, but we do not expect the OBBB Act to materially impact our effective tax rate or cash flows in the current fiscal year.

While we have issued composition-of-matter patents covering reproxalap and certain of our other product candidates in the United States and other countries, filing, prosecuting, and defending patents on reproxalap and our other product candidates in all countries throughout the world would be prohibitively expensive, and our intellectual property rights in some countries outside the United States may be less extensive and of significantly shorter duration than those in the United States. In addition, the laws of some foreign countries do not protect intellectual property rights to the same extent as federal and state laws in the United States. Consequently, we may not be able to prevent third parties from practicing our inventions in all countries outside the United States, or from selling or importing products made using our inventions in and into the United States or other jurisdictions.

As of June 30, 2025, we only had 8 full-time employees. We currently plan to commercialize reproxalap through a collaboration with AbbVie, should AbbVie choose to exercise the Option.

In addition, we expect that we will need to grow our organization to continue development and pursue the potential commercialization of our other product candidates, as well as function as a public company. As we seek to advance reproxalap, alone or with others, and other product candidates towards potential commercialization, increase the number of ongoing product development programs, and advance our future product candidates through preclinical studies and clinical trials, we will need to expand our financial, development, regulatory, manufacturing, marketing, and sales capabilities, or contract with third parties to provide these capabilities for us. As our operations expand, we expect that we will need to manage additional relationships with various strategic partners, suppliers, and other third parties. Future growth will impose significant added responsibilities on members of management and require us to retain additional internal capabilities. Our future financial performance and our ability to commercialize our product candidates and to compete effectively will depend, in part, on our ability to manage any future growth effectively. To that end, we must be able to manage our development efforts and clinical trials effectively, and hire, train, and integrate additional clinical and regulatory, financial, administrative and sales, and marketing personnel. We may not be able to identify, recruit, or integrate additional personnel, and our failure to do so could prevent us from successfully growing our company.
