By Alex Philippidis - February 26, 2025 - The FDA has granted Priority Review to Precigen’s Biologics License Application (BLA) for its lead candidate PRGN-2012, the company said—a step forward for a gene therapy that, if approved, would be the first treatment indicated for adults with the rare disease of recurrent respiratory papillomatosis (RRP).
The FDA also set an August 27 target date for deciding on Precigen’s BLA under the Prescription Drug User Fee Act (PDUFA). PRGN-2012—which Precigen has begun to call by its generic name of zopapogene imadenovec—is a gene therapy designed to elicit immune responses directed against cells infected with human papillomavirus (HPV) 6 or HPV 11.
