• Prescription Drug User Fee Act (PDUFA) goal date of December 31, 2025

ISELIN, N.J., Nov. 13, 2025 (GLOBE NEWSWIRE) -- Outlook Therapeutics, Inc. (Nasdaq: OTLK), a biopharmaceutical company focused on enhancing the standard of care for bevacizumab for the treatment of retina diseases, today announced that the U.S. Food and Drug Administration (FDA) has acknowledged receipt of the resubmission of the Biologics License Application (BLA) for ONS-5010 (bevacizumab-vikg), an investigational ophthalmic formulation of bevacizumab for the treatment of wet age-related macular degeneration (wet AMD). The FDA has advised that it considers the BLA resubmission a complete, Class 1 response to the August 27, 2025 action letter, which results in a 60 day review period from the date of resubmission. As a result, the FDA has set a Prescription Drug User Fee Act (PDUFA) goal date of December 31, 2025. ONS-5010, if approved, will be branded as LYTENAVA™ (bevacizumab-vikg) for the treatment of wet AMD.

“We are pleased that the FDA has accepted our resubmission of the BLA for ONS-5010 (bevacizumab-vikg), marking another important milestone in our effort to bring the first and only FDA-approved ophthalmic formulation of bevacizumab to patients in the United States suffering from wet AMD. Our team has worked diligently to address the feedback from the agency, strengthen the resubmitted BLA and resolve the outstanding issue highlighted in the Complete Response Letter (CRL) from August 2025,” commented Bob Jahr, Chief Executive Officer of Outlook Therapeutics.

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

ONS-5010/LYTENAVA™ is an ophthalmic formulation of bevacizumab produced in the United States 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.
