EyePoint Pharmaceuticals (EYPT) Risk Analysis

Even if our clinical trials are successfully completed as planned, the results may not support approval of DURAVYU or our other product candidates under the laws and regulations of the FDA or other regulatory authorities outside the United States. The clinical trial process may fail to demonstrate that our product candidates are both safe and effective for their intended uses. Pre-clinical and clinical data and analyses are often able to be interpreted in different ways. Even if we view our results favorably, if a regulatory authority has a different view, we may still fail to obtain regulatory approval of our product candidates. This, in turn, would significantly adversely affect our business prospects.

From time to time, we may publicly disclose interim, top-line, initial or preliminary data from our clinical trials, which is based on a preliminary analysis of then-available data, and the results and related findings and conclusions are subject to change following a more comprehensive review of the data. When reporting interim, top-line, initial or preliminary data from an ongoing trial, we may make assumptions, estimations, calculations and conclusions as part of our analyses of data, and may not have received or had the opportunity to fully and carefully evaluate all data. As a result, the interim, top-line, initial or preliminary results that we report may differ from future results of the same trials, or different conclusions or considerations may qualify such results, once additional data have been received and fully evaluated. Interim, top-line, initial and preliminary data from clinical trials are subject to the risk that one or more of the clinical outcomes may materially change as patient enrollment continues and more patient data become available. Interim, top-line, initial and preliminary data also remain subject to audit and verification procedures that may result in the final data being materially different from the interim, top-line, initial or preliminary data we previously published. As a result, interim, top-line, initial and preliminary data should be viewed with caution until the final data are available. Adverse differences between interim, top-line, initial or preliminary data and final data could significantly harm our business prospectus and may cause the price of our common stock to fluctuate or decline. Further, regulatory agencies and others, may not accept or agree with our assumptions, estimates, calculations, conclusions or analyses or may interpret or weigh the importance of data differently, which could adversely impact the potential of the particular program, the likelihood of obtaining regulatory approval of the particular product candidate, commercialization of any approved product and the business prospects of the company in general. In addition, the information we choose to publicly disclose regarding a particular study or clinical trial is derived from information that is typically extensive, and you or others may not agree with what we determine is material or otherwise appropriate information to include in our disclosure. If the interim, top-line, initial or preliminary data that we report differs from actual results, or if regulatory authorities or others, disagree with the conclusions reached, our ability to obtain approval for, and commercialize, our product candidates may be significantly impaired, which could materially harm our business, operating results, prospects or financial condition.

Because we have limited financial and managerial resources, we focus on research programs and product candidates for specific indications. Specifically, with regard to DURAVYU, we have focused our efforts on the treatment of wet AMD and DME. As a result, we may forego or delay pursuit of opportunities with DURAVYU or other product candidates for the treatment of other indications that later prove to have greater commercial potential. Our resource allocation decisions may cause us to fail to capitalize on viable commercial products or profitable market opportunities. Our spending on current and future research and development programs and product candidates for specific indications may not yield any commercially viable products. Furthermore, until such time as we are able to build a broader product candidate pipeline, if ever, any adverse developments with respect to our leading product candidate, DURAVYU, would have a more significant adverse effect on our overall business than if we maintained a broader portfolio of product candidates. We have historically based our research and development efforts primarily on our proprietary technologies for the treatment of chronic eye diseases. As a result of pursuing the development of product candidates using our proprietary technologies, we may fail to develop product candidates or address indications based on other scientific approaches that may offer greater commercial potential or for which there is a greater likelihood of success. Research programs to identify new product candidates require substantial technical, financial and human resources. These research programs may initially show promise in identifying potential product candidates, yet fail to yield product candidates for clinical development.

Results from pre-clinical testing, early clinical trials, prior clinical trials, investigator-sponsored studies, and other data and information often do not accurately predict final pivotal clinical trial results. DURAVYU relies on vorolanib as its active pharmaceutical agent. Vorolanib is a small molecule tyrosine kinase inhibitor ("TKI") that has been previously studied by Tyrogenex in Phase 1 and 2 clinical trials as an orally delivered therapy for the treatment of wet AMD. The Phase 2 clinical trial was discontinued due to systemic toxicity. There can be no assurance that such systemic toxicities will not occur in our clinical trial for DURAVYU. In addition, data from one pivotal clinical trial may not be predictive of the results of other pivotal clinical trials for the same product candidate, even if the trial designs are the same or similar. Further, as of now, TKIs have not yet been approved, and there is no guarantee of approval, for use in the field of Ophthalmology. Data obtained from pre-clinical studies and clinical trials are susceptible to varying interpretations, which may delay, limit or prevent regulatory approval. Adverse side effects may be observed in clinical trials that delay, limit or prevent regulatory approval, and even after a product candidate has received marketing approval, the emergence of adverse side effects in more widespread clinical practice may cause the product's regulatory approval to be limited or even rescinded. Additional trials necessary for approval may not be undertaken or may ultimately fail to establish the safety and efficacy of our product candidates. In addition, while the clinical trials of our product candidates, including our lead product candidate, DURAVYU, are designed based on the available relevant information, in view of the uncertainties inherent in drug development, such clinical trials may not be designed with a focus on indications, patient populations, dosing regimens, safety or efficacy parameters or other variables that will provide the necessary safety and efficacy data to support regulatory approval to commercialize the product. In addition, the methods we select to assess particular safety or efficacy parameters may not yield statistically significant results regarding our product candidates' effects on patients. Even if we believe the data collected from clinical trials of our product candidates are promising, these data may not be sufficient to support approval by the FDA or foreign regulatory authorities. Pre-clinical and clinical data can be interpreted in different ways. Accordingly, the FDA or foreign regulatory authorities could interpret these data in different ways from us or our partners, which could delay, limit or prevent regulatory approval.

Identifying and qualifying patients to participate in clinical trials of our product candidates, including DURAVYU, is critical to our success. The timing of our clinical trials depends in part on the speed at which we can recruit patients to participate in testing our product candidates. If patients are unwilling to participate in our trials because of negative publicity from adverse events in the biotechnology industries, public perception of vaccine safety issues or for other reasons, including competitive clinical trials for similar patient populations, the timeline for recruiting patients, conducting studies, and obtaining regulatory approval of potential products may be delayed. These delays could result in increased costs, delays in advancing our product development, delays in testing the effectiveness of our technology or termination of the clinical trials altogether. We may not be able to identify, recruit, and enroll a sufficient number of patients, or those with required or desired characteristics to achieve diversity in a clinical trial, or complete our clinical trials in a timely manner. Patient enrollment is affected by a variety of factors including, among others: - severity of the disease under investigation;- design of the trial protocol and size of the patient population required for analysis of the trial's primary endpoints;- size of the patient population;- eligibility criteria for the trial in question;- perceived risks and benefits of the product candidate being tested;- willingness or availability of patients to participate in our clinical trials;- proximity and availability of clinical trial sites for prospective patients;- our ability to recruit clinical trial investigators with the appropriate competencies and experience, and adequate research staffing to support multiple, concurrent clinical trials;- availability of competing therapies and related clinical trials;- efforts to facilitate timely enrollment in clinical trials;- our ability to obtain and maintain patient consents;- the risk that patients enrolled in clinical trials will drop out of the trials before completion;- patient referral practices of physicians; and - ability to monitor patients adequately during and after treatment. We may not be able to initiate or continue clinical trials if we cannot enroll a sufficient number of eligible patients to participate in the clinical trials required by regulatory agencies. Even if we enroll a sufficient number of eligible patients to initiate our clinical trials, we may be unable to maintain participation of these patients throughout the course of the clinical trial as required by the clinical trial protocol, in which event we may be unable to use the research results from those patients. If we have difficulty enrolling and maintaining the enrollment of a sufficient number of patients to conduct our clinical trials as planned, we may need to delay, limit, or terminate ongoing or planned clinical trials, any of which would have an adverse effect on our business.

A significant element of our strategy is to focus on innovation and new therapeutic development. The biopharmaceutical market in which we participate is highly competitive. In addition, the market in which we participate and healthcare industry generally are characterized by extensive research and development and rapid technological change. New development requires significant investment in research and development, clinical trials and regulatory approvals. The results of our development efforts may be affected by a number of factors, including our ability to anticipate customer needs, innovate and develop new therapeutics, effectively use artificial intelligence (AI) and machine learning capabilities, successfully complete clinical trials, obtain regulatory approvals in the United States and abroad, manufacture products in a cost-effective manner, obtain appropriate intellectual property protection for our products, and gain and maintain market acceptance of our therapeutics. In addition, patents attained by others could preclude or delay our commercialization of a product. There can be no assurance that any products now in development or that we may seek to develop in the future will achieve feasibility, obtain regulatory approval or gain market acceptance. If we fail to develop new therapeutics or if competitive technologies or therapeutic alternatives emerge and gain market acceptance, such events could have a material adverse effect on our business, financial condition or results of operations.

Our business and future success depends heavily on our ability to successfully develop, obtain regulatory approval for and successfully commercialize our lead product candidate, DURAVYU, which is currently in Phase 3 global, clinical trials for wet AMD and DME. DURAVYU is our only product candidate in late-stage clinical development and we expect that a substantial portion of our efforts and expenses over the coming years will be devoted to the continued development of DURAVYU. If such clinical trials fail to demonstrate safety and efficacy to the satisfaction of the FDA or other regulatory authorities or do not otherwise produce clear or favorable results, we may incur additional costs or experience delays in completing, or ultimately be unable to complete, the development and commercialization of DURAVYU. We cannot accurately predict when or if any DURAVYU will prove effective or safe in humans or whether it will receive marketing approval or reach successful commercialization. If we are unable to complete clinical development and obtain regulatory approval for DURAVYU in one or more indications and in a timely manner, our business, financial condition, results of operations and prospects will be significantly harmed. Further, in the event DURAVYU is approved for marketing but does not gain an adequate level of acceptance among physicians, patients and third parties, we may not generate significant product revenues or become profitable. Market acceptance by physicians, patients and third party payors of DURAVYU or other products we may commercialize in the future will depend on a number of factors, some of which are beyond our control, including: - their efficacy, safety, and other potential advantages in relation to alternative treatments;- their relative convenience and ease of administration;- the availability of adequate coverage or reimbursement by third parties, such as insurance companies and other healthcare payors, and by government healthcare programs, including Medicare and Medicaid;- the prevalence and severity of adverse events;- their cost of treatment in relation to alternative treatments, including generic products;- the extent and strength of our third party manufacturer and supplier support;- the extent and strength of marketing and distribution support;- the limitations or warnings contained in a product's approved labeling; and - distribution and use restrictions imposed by the FDA or other regulatory authorities outside the United States. For example, even if DURAVYU gains approval by the FDA, physicians and patients may not immediately be receptive to it and may be slow to adopt it. If DURAVYU does not achieve an adequate level of acceptance among physicians, patients and third party payors, we may not generate meaningful revenues from DURAVYU and we may not become profitable.
