Insights

Biotech regulatory analyst

FDA accepted the BLA resubmission, set a Class 1 review and PDUFA date.

The FDA’s acknowledgment of the ONS-5010 BLA resubmission moves the program back into active review. A Class 1 designation indicates a shorter, two-month review window from resubmission, typically used for limited revisions.

This step does not imply approval but confirms the file is sufficiently complete for review. The agency set a PDUFA goal date of December 31, 2025, providing a specific decision timeline.

The next concrete milestone is the PDUFA date on December 31, 2025. Outcomes will depend on the adequacy of the resubmission addressing prior issues and the FDA’s final assessment.
