Previous wording

To generate revenue, we will depend on FDA approval and successful commercialization of reproxalap. Our success in obtaining regulatory approval of reproxalap from the FDA depends on whether we successfully address the issues raised by the FDA in the 2026 Complete Response Letter, and our ability to address any issues the FDA may raise in the future. If we are unable to successfully obtain FDA approval, or FDA approval is delayed or limited, our ability to generate revenue will be significantly delayed.

Previous wording

We will require substantial additional financing, and a failure to obtain this necessary capital when needed on acceptable terms, or at all, could force us to delay, limit, reduce, or terminate our product development, other operations or commercialization efforts.

Previous wording

On March 17, 2026, we announced that we had received a Complete Response Letter from the FDA (the 2026 Complete Response Letter). The 2026 Complete Response Letter stated that there is “a lack of substantial evidence consisting of adequate and well-controlled investigations … that the drug product will have the effect it purports or is represented to have under the conditions of use prescribed, recommended, or suggested in its proposed labeling” and that “the application has failed to demonstrate efficacy in adequate and well controlled studies in the treatment of signs and symptoms of dry eye disease.” The 2026 Complete Response Letter also stated that the “inconsistency of study results raises serious concerns about the reliability and meaningfulness of the positive findings” and that the “totality of evidence from the completed clinical trials does not support the effectiveness of the product.” We have scheduled a Type A meeting with the FDA to understand the actions needed for approval of the reproxalap NDA.

On July 15, 2026, we requested a clarification of the Minutes from the FDA. In addition, we intend to request a Type D meeting with the FDA to discuss potential resubmission of the Reproxalap NDA. The Type D meeting is expected to be held by the end of the third quarter of 2026. A Type D meeting is intended to facilitate focused discussion on a limited number of specific issues, but there can be no assurance that the FDA will agree with our proposed approach. If the FDA requires us to conduct a additional clinical trials, we could incur additional costs and delays, to the extent any such trial is more complex, time-consuming and/or expensive to design, initiate and complete. Furthermore, we may decide to submit a formal dispute resolution request to the FDA as a follow-up to our recent Type A and Type D meetings regarding the 2026 Complete Response Letter.

Previous wording

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 three months ended March 31, 2026 and 2025 was approximately $3.5 million and $9.9 million, respectively. As of March 31, 2026, we had total stockholders’ equity of $42.2 million and an accumulated deficit of $487.4 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.

Previous wording

We were a party to a credit facility with Hercules Capital until we fully repaid all outstanding obligations on April 1, 2026. If we raise any debt financing, the terms of such debt could restrict our operating and financial flexibility. Restrictions may include, among other things, limitations on borrowing and specific restrictions on the use of our assets, as well as prohibitions on our ability to create liens, pay dividends, redeem capital stock, or make investments. If we default under the terms of any future debt facility, the lender may accelerate all of our repayment obligations and take control of our pledged assets, potentially requiring us to renegotiate our agreement on terms less favorable to us or to immediately cease operations. Further, if we are liquidated, the lender’s right to repayment would be senior to the rights of the holders of our common stock. The lender could declare a default upon the occurrence of any event that they interpret as a material adverse effect as defined under the loan agreement. Any declaration by the lender of an event of default could significantly harm our business and prospects and could cause the price of our common stock to decline. If we raise any additional debt financing, the terms of such additional debt could further restrict our operating and financial flexibility.

Previous wording

As of March 31, 2026, we had only 7 full-time employees and, as a result, we rely, and expect to continue to rely, on outsourcing arrangements for a significant portion of our activities, including clinical research, data collection and analysis, manufacturing, commercial readiness preparations, financial reporting and accounting, and human resources, as well as for certain functions required of publicly traded companies. We may have limited control over third parties and we cannot guarantee that any third-party will perform its obligations in an effective and timely manner.

Previous wording

As of March 31, 2026, we only had 7 full-time employees. We currently plan to commercialize reproxalap through a collaboration with AbbVie, should AbbVie choose to exercise the AbbVie Option. However, if AbbVie elects not to exercise the AbbVie Option, we may need to grow our organization to continue development and pursue the potential commercialization of reproxalap, either alone or with another third party. 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.

Previous wording

As of March 31, 2026, our executive officers, directors, and greater than 5% stockholders, in the aggregate, own approximately 25% of our outstanding common stock. As a result, such persons, acting together, may have the ability to control our management and business affairs and substantially all matters submitted to our stockholders for approval, including the election and removal of directors and approval of any significant transaction. Concentration of ownership may have the effect of delaying, deferring, or preventing a change in control, impeding a merger, consolidation, takeover, or other business combination involving us, or discouraging a potential acquirer from making a tender offer or otherwise attempting to obtain control of our business, even if such a transaction would benefit other stockholders.
