• Shareholders: Positive impact due to a clearer path to potential product approval and commercialization, which could increase company value.
• Patients: Potential for a new FDA-approved treatment option for nAMD, improving access to a standardized and regulated ophthalmic formulation of bevacizumab.
• Healthcare Providers: Availability of an approved ophthalmic bevacizumab formulation may simplify treatment protocols and enhance confidence in its efficacy and safety.

Next Steps

• Work with the FDA Division of Ophthalmology and Office of Specialty Medicine to reach an agreement on final labeling.
• Resubmit the BLA for ONS-5010/LYTENAVA in June 2026 as a Class 1 resubmission.
• Await a PDUFA date and decision within 60 days of the FDA's receipt of the resubmission.

Key Dates

Recommendation

While the FDA appeal win is a significant positive, the company still needs to finalize labeling and await final approval. The path to commercialization and profitability remains subject to market adoption and competition. Therefore, a 'hold' recommendation is prudent pending further clarity on the approval timeline and market strategy.
