Outlook Therapeutics submits SPA to FDA for non-inferiority study of ONS-5010

Outlook Therapeutics 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 naive 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. 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.
