• Phase 3 Trial Accelerated Pathway

  PDS Biotech amended its VERSATILE-003 Phase 3 clinical trial protocol to include Progression-Free Survival (PFS) as an interim primary endpoint, aiming for an accelerated approval pathway for PDS0101 in HPV16-positive head and neck cancer. This change is expected to shorten trial duration and reduce costs.

• Encouraging Phase 2 Data

  Early results from an NCI-led Phase 2 trial for PDS01ADC in metastatic castration-resistant prostate cancer showed a median PFS of 9.6 months and a 40% median PSA decline, with 6 of 16 patients achieving over 50% PSA decline.

• Extended IP Protection

  New patents were granted in the U.S. and Japan for PDS0101, extending market protection for the Versamune® platform into the 2040s.

• Full Year 2025 Financials

  The company reported a net loss of $34.5 million, or $0.74 per share, for the full year 2025, an improvement from $37.6 million ($1.03 per share) in 2024, with reduced operating expenses and a cash balance of $26.7 million as of December 31, 2025.

This filing contains highly material positive updates for PDS Biotechnology. The amendment to the VERSATILE-003 Phase 3 trial, which introduces Progression-Free Survival (PFS) as an interim primary endpoint, is a critical development that could significantly shorten the trial duration, reduce costs, and accelerate the path to potential accelerated FDA approval for its lead candidate, PDS0101. This de-risks the program and brings a potential market entry closer. Additionally, encouraging early Phase 2 results for PDS01ADC in prostate cancer and extended intellectual property protection for PDS0101 further strengthen the company's pipeline and long-term prospects. While the company reported a net loss for 2025, the strategic clinical advancements and financial discipline (reduced operating expenses) are the dominant market-moving factors. Investors should monitor the progress of the amended Phase 3 trial and future data readouts.
