Outlook Therapeutics® Re-Submits Biologics License Application for ONS-5010 as a Treatment for Wet AMD to the U.S. Food and Drug Administration

Outlook Therapeutics, Inc. (Nasdaq: OTLK), a biopharmaceutical company that achieved regulatory approval in the European Union (EU) and the United Kingdom (UK) for the first authorized use of an ophthalmic formulation of bevacizumab for the treatment of wet age-related macular degeneration (wet AMD), today announced it has re-submitted its Biologics License Application (BLA) to the U.S. Food and Drug Administration (FDA) for ONS-5010, an investigational ophthalmic product which, if approved, will be branded as LYTENAVA™ (bevacizumab-vikg) for the treatment of wet age-related macular degeneration (wet AMD).
'We remain committed to bringing an ophthalmic bevacizumab to market in the United States and providing retina patients suffering from wet AMD with a much needed treatment option that has the potential to address the problems associated with unapproved repackaged bevacizumab. Our team has worked diligently to address the FDA's requests and we believe this resubmission provides the necessary evidence to support approval of the ONS-5010 BLA in the United States,' commented Lawrence Kenyon, Chief Financial Officer and Interim Chief Executive Officer of Outlook Therapeutics. 'This resubmission marks a very significant milestone and puts us another step closer to a transformed Outlook Therapeutics.'
The ONS-5010 BLA resubmission is based on the efficacy and safety demonstrated in NORSE EIGHT, as well as additional chemistry, manufacturing and controls (CMC) information requested by the FDA. As previously announced, following Type A meetings with the FDA in Q4 CY2023 to address the ONS-5010 Complete Response Letter (CRL), the FDA informed Outlook Therapeutics that, in order to meet the FDA's requirement for a second adequate and well-controlled clinical trial of ONS-5010, it could conduct a non-inferiority study evaluating ONS-5010 versus ranibizumab in a 12 week study of treatment naïve patients with a primary efficacy endpoint at 8 weeks (NORSE EIGHT). Outlook Therapeutics believes that the complete data set for NORSE EIGHT and the additional CMC information in the BLA resubmission, combined with the data from the other NORSE clinical trials, provides the required evidence to support approval of the ONS-5010 BLA in the United States. A decision from the FDA is expected within six months.
NORSE EIGHT was a randomized, controlled, parallel-group, masked, non-inferiority study of 400 newly diagnosed, wet AMD subjects randomized in a 1:1 ratio to receive 1.25 mg ONS-5010 / LYTENAVA™ or 0.5 mg ranibizumab intravitreal injections. Subjects received injections at Day 0 (randomization), Week 4, and Week 8 visits. The primary endpoint is the mean change in best corrected visual acuity (BCVA) from baseline to week 8. In November 2024, Outlook Therapeutics reported that in NORSE EIGHT, ONS-5010 demonstrated a mean 4.2 letter improvement in best corrected visual acuity (BCVA), which did not meet the pre-specified non-inferiority endpoint at week 8 set forth in the special protocol assessment (SPA) with the FDA.
In January 2025, Outlook Therapeutics announced results from the completed analysis of the 12-week safety and efficacy results for NORSE EIGHT, which indicated that ONS-5010 demonstrated clinically meaningful anatomic and functional improvements at each study timepoint. BCVA data across all study timepoints demonstrated an improvement in vision, increasing over time, and the presence of biologic activity. Results from the 12-week analysis demonstrated a mean improvement in BCVA of 3.3 to 5.5 letters in the ONS-5010 arm across the 4, 8, and 12 week timepoints measured in the study, compared to a mean 4.5 to 6.5 letter improvement in the ranibizumab arm over the same timepoints. Additionally, the complete NORSE EIGHT data set showed that anatomical response was similar between treatments, with a reduction in central retinal thickness of -123.9 microns for ONS-5010 treated eyes and -127.3 microns for the ranibizumab group, virtually no difference between the arms. Central retinal thickness is a key indicator of effectiveness used by retina specialists in the treatment of wet AMD.
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 European Union (EU) and Marketing Authorization granted by the Medicines and Healthcare products Regulatory Agency (MHRA) in the United Kingdom (UK) for the treatment of wet AMD.
In the United States, ONS-5010 / LYTENAVA™ (bevacizumab-vikg) is investigational.
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.
About Outlook Therapeutics, Inc.
Outlook Therapeutics is a biopharmaceutical company focused on the development and commercialization of ONS-5010/LYTENAVA™ (bevacizumab-vikg; bevacizumab gamma), for the treatment of retina diseases, including wet AMD. LYTENAVA™ (bevacizumab gamma) is the first ophthalmic formulation of bevacizumab to receive European Commission and MHRA Marketing Authorization for the treatment of wet AMD. Outlook Therapeutics is working to initiate its commercial launch of LYTENAVA™ (bevacizumab gamma) in the EU and the UK as a treatment for wet AMD, expected in the second quarter of calendar 2025. In the United States, ONS-5010/LYTENAVA™ is investigational, and a BLA has been resubmitted to the FDA in the United States. If approved in the United States, ONS-5010/LYTENAVA™, would be the first approved ophthalmic formulation of bevacizumab for use in retinal indications, including wet AMD.
