Outlook Therapeutics Requests FDA Meeting To Clarify Confirmatory Evidence Requirements For ONS-5010 Wet AMD Biologics License Application

Outlook Therapeutics, Inc. (NASDAQ:OTLK), a biopharmaceutical company focused on optimizing the standard of care for bevacizumab for the treatment of retina diseases, today announced that a Type A Meeting request has been submitted to the U.S. Food and Drug Administration (FDA) to discuss the complete response letter (CRL) dated August 27, 2025 regarding the biologics license application (BLA) resubmission for ONS-5010, an investigational ophthalmic formulation of bevacizumab under development to treat wet AMD.

In the FDA's recently issued CRL, although the Agency acknowledged the NORSE TWO pivotal trial met its safety and efficacy endpoints, it recommended that confirmatory evidence of efficacy be submitted to support the application for ONS-5010. The requested Type A meeting seeks to clarify the details of the confirmatory evidence required by the FDA.

"We believe this Type A meeting will provide us with additional clarity on the FDA's requirements to remedy the deficiency identified in the CRL," commented Bob Jahr, Chief Executive Officer of Outlook Therapeutics. "The Outlook Therapeutics team remains dedicated to our mission to provide patients in the U.S. with a safe and effective alternative to compounded bevacizumab, which has been used off-label as a first-line treatment for wet-AMD for years despite concerns around potency, sterility, consistency and regulatory oversight associated with the use of compounded products."

About ONS-5010/LYTENAVA™ (bevacizumab-vikg, bevacizumab gamma)

ONS-5010/LYTENAVA™ is an ophthalmic formulation of bevacizumab for the treatment of wet AMD. LYTENAVA™ (bevacizumab gamma) is the subject of a centralized Marketing Authorization granted by the European Commission in the EU and Marketing Authorization granted by the Medicines and Healthcare products Regulatory Agency (MHRA) in the UK for the treatment of wet AMD.

In the United States, ONS-5010/LYTENAVA™ (bevacizumab-vikg) is investigational. In certain European Union Member States ONS-5010/LYTENAVA™ must receive pricing and reimbursement approval before it can be sold.

Bevacizumab-vikg (bevacizumab gamma in the EU and UK) is a recombinant humanized monoclonal antibody (mAb) that selectively binds with high affinity to all isoforms of human vascular endothelial growth factor (VEGF) and neutralizes VEGF's biologic activity through a steric blocking of the binding of VEGF to its receptors Flt-1 (VEGFR-1) and KDR (VEGFR-2) on the surface of endothelial cells. Following intravitreal injection, the binding of bevacizumab to VEGF prevents the interaction of VEGF with its receptors on the surface of endothelial cells, reducing endothelial cell proliferation, vascular leakage, and new blood vessel formation in the retina.
