Outlook Therapeutics Submits Special Protocol Assessment (SPA) to FDA for Non-Inferiority Study of ONS-5010

• NORSE EIGHT study on track to commence in Q1 2024
• Resubmission of ONS-5010 Biologics License Application (BLA) in the U.S. expected by the end of calendar year 2024

ISELIN, N.J., Dec. 19, 2023 (GLOBE NEWSWIRE) -- Outlook Therapeutics, Inc. (Nasdaq: OTLK), a biopharmaceutical company working to achieve FDA approval for the first ophthalmic formulation of bevacizumab for the treatment of retinal diseases, today announced that, following receipt of written confirmation of the NORSE EIGHT proposed clinical trial protocol with the U.S. Food and Drug Administration (FDA), Outlook Therapeutics has submitted a Special Protocol Assessment (SPA) request for the required additional adequate and well-controlled study of ONS-5010.

As previously announced, following the Type A meeting with the FDA held in October 2023, the FDA informed Outlook Therapeutics that it can conduct a non-inferiority study evaluating ONS-5010 versus ranibizumab in a 3-month study of treatment naïve patients with a primary efficacy endpoint at 2 months. Subsequently, as discussed with and recommended by the FDA, Outlook Therapeutics submitted a clinical trial protocol and requested a Type A meeting with the FDA for feedback. The FDA has since provided written feedback on the protocol, which Outlook Therapeutics has incorporated. The revised protocol is the subject of the SPA request, in which Outlook Therapeutics is seeking further confirmation from the FDA that NORSE EIGHT, if successful, addresses the FDA’s requirement for a second adequate and well-controlled clinical trial to support the resubmission of the ONS-5010 BLA for wet AMD. The FDA is expected to provide a response to the SPA in early February 2024.

NORSE EIGHT will be a randomized, controlled, parallel-group, masked study of neovascular age-related macular degeneration subjects randomized in a 1:1 ratio to receive 1.25 mg ONS-5010 or 0.5 mg ranibizumab intravitreal injections. Subjects will receive injections at Day 0 (randomization), Week 4, and Week 8 visits. Approximately 400 patients are expected to be enrolled in the study.

Outlook Therapeutics expects to resubmit the ONS-5010 BLA by the end of calendar year 2024 to include the results of NORSE EIGHT and the additional CMC work to address the issues identified by FDA in the Complete Response Letter issued in August 2023 to support approval.

“We have been working closely with FDA to meet the remaining requirements provided by the Agency to support approval of ONS-5010. Based on our ongoing discussions with FDA, we believe we have agreement on a clinical trial protocol. With the SPA now submitted, we are preparing to start NORSE EIGHT in the first quarter of 2024,” commented Russell Trenary, President and Chief Executive Officer of Outlook Therapeutics. “We remain dedicated in our pursuit to achieve U.S. FDA approval for the first ophthalmic formulation of bevacizumab and look forward to providing further updates.”
