ISELIN, N.J., June 16, 2026 — 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 the U.S. Food and Drug Administration (FDA) has acknowledged receipt of the resubmission of the Biologics License Application (BLA) for ONS-5010/LYTENAVA™ for the treatment of neovascular age-related macular degeneration (nAMD), or wet AMD. The Company has been informed that the resubmission is a Class 1 review, with a PDUFA target action date of July 29, 2026.
“We are very pleased that the FDA has accepted our resubmitted BLA to review the labelling as part of the final step toward potential approval,” said Bob Jahr, Chief Executive Officer of Outlook Therapeutics. “This is great news for Outlook and the LYTENAVA™ team, patients and the retina community. We look forward to collaborating with the FDA over the coming weeks. We are incredibly grateful to our teams, partners, and KOLs for their resilience and dedication.”
When approved, ONS-5010/LYTENAVA™ will be the first and only FDA-approved ophthalmic formulation of bevacizumab supported by standardized manufacturing, FDA-approved labeling, and robust pharmacovigilance. Outlook Therapeutics has initiated pre-launch activities in anticipation of the pending BLA approval.
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 certain European Union Member States, ONS-5010/LYTENAVA™ must receive pricing and reimbursement approval before it can be sold.
In the United States, ONS-5010/LYTENAVA ™ (bevacizumab-vikg) is investigational. When approved, it will be the first ophthalmic formulation approved by the FDA.
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.
