PDS Biotechnology announces FDA alignment on use of PFS as primary endpoint

PDS Biotechnology (PDSB) announced that the Company has submitted a protocol amendment to the U.S. FDA for its Phase 3 VERSATILE-003 clinical trial. The proposed amendment to the VERSATILE-003 Phase 3 trial changes the PFS endpoint to a primary endpoint that can be evaluated earlier with significant statistical power, potentially providing the basis for accelerated approval of PDS0101. Median overall survival remains the primary endpoint for full approval as originally recommended by FDA. The submission follows a constructive Type C meeting held with the FDA in December 2025 to discuss the proposed accelerated approval pathway for PDS0101 in HPV16-positive recurrent and/or metastatic Head and Neck Cancer. The amendment is supported by positive final results from the Company’s VERSATILE-002 trial, which showed promising mOS and durable PFS.
