The Company is committed to developing and commercializing innovative therapeutics to improve the lives of patients with serious retinal diseases. The Company's pipeline leverages its proprietary bioerodible Durasert E™ technology (Durasert E™) for sustained intraocular drug delivery. The Company’s lead product candidate, DURAVYU™1, f/k/a EYP-1901, is an investigational sustained delivery treatment for vascular endothelial growth factor (VEGF) mediated retinal diseases combining vorolanib, a selective and patent-protected tyrosine kinase inhibitor with Durasert E™. DURAVYU™ is currently intwo global Phase 3 clinical trials (LUGANO and LUCIA) for wet age-related macular degeneration (wet AMD), the leading cause of vision loss among people 50 years of age and older in the United States. DURAVYU™ also completed a Phase 2 clinical trial in diabetic macular edema (DME) meeting primary and secondary endpoints. Additional pipeline programs include EYP-2301, a promising TIE-2 agonist, razuprotafib, formulated in Durasert E™ to potentially improve outcomes in serious retinal diseases.

On May 27, 2025, the Company announced enrollment was completed in the pivotal Phase 3 LUGANO clinical trial evaluating DURAVYU™. The Company is focused on completing patient enrollment in the LUCIA clinical trial for DURAVYU™ in the third quarter of 2025 and reporting top-line data for both the LUGANO and LUCIA clinical trials in the second half of 2026. The Company completed a positive EOP2 meeting with the US FDA in July 2025 and is waiting for the formal meeting minutes to finalize the pivotal program for DURAVYU™ in DME with an anticipated start in 2026.

Liquidity

The Company had cash, cash equivalents and investments in marketable securities of$255.7 million at June 30, 2025. The Company has a history of operating losses and has not had significant recurring cash inflows from revenue. The Company’s operations have been financed primarily from sales of its equity securities, issuance of debt and a combination of license fees, milestone payments, royalty income, and other fees received from its collaboration partners. The Company anticipates that it will continue to incur losses as it continues the research and development of its product candidates, and the Company does not expect revenues to generate sufficient funding to sustain its operations in the near-term. The Company expects to continue fulfilling its funding needs through cash inflows from licensing and research collaboration transactions, additional equity capital raises and other arrangements. The Company believes that its cash, cash equivalents and investments in marketable securities of$255.7 million at June 30, 2025 will enable the Company to fund its current and planned operations for at least the next twelve months from the date these condensed consolidated financial statements were issued. Actual cash requirements could differ from management’s projections due to many factors, including the timing and results of the Company’s clinical trials for DURAVYU™, additional investments in research and development programs, competing technological and market developments and the costs of any strategic acquisitions and/or development of complementary business opportunities.

1. DURAVYU™ has been conditionally accepted by the FDA as the proprietary name for EYP-1901. DURAVYU is an investigational product candidate; it has not been approved by the FDA. FDA approval and the timeline for potential approval is uncertain.
