Outlook Therapeutics has requested a Type A meeting with the FDA to discuss a Complete Response Letter (CRL) for its Biologics License Application (BLA) for ONS-5010, an investigational treatment for wet AMD. The CRL, dated December 31, 2025, cited a purported lack of substantial evidence of effectiveness, recommending additional confirmatory evidence. This development is a significant setback for the company, especially given its small market capitalization, as ONS-5010 is a key pipeline asset. The company stated the CRL was unexpected and believes it is inconsistent with the totality of evidence submitted, including data from its Phase 3 NORSE TWO study. While the request for a Type A meeting is a standard procedure to clarify and address FDA concerns, it introduces further uncertainty and potential delays in the approval pathway for ONS-5010 in the United States.
