PDS Biotechnology Corporation (Nasdaq: PDSB), a clinical-stage immunotherapy company developing a growing pipeline of targeted cancer immunotherapies and infectious disease vaccines based on the Company’s proprietary Versamune® and Infectimune™ T cell activating technologies, today announced that its independent Data Monitoring Committee (DMC) met for its scheduled review of PDS0101 in combination with Merck’s anti-PD-1 therapy, KEYTRUDA® (pembrolizumab) for the potential treatment of recurrent or metastatic HPV16-positive head and neck cancer.
Data from the 43 patients included both Stage 1 and Stage 2 checkpoint inhibitor (CPI) naïve subjects and Stage 1 CPI refractory subjects in the safety analysis. Assessment of clinical efficacy was not a focus of the DMC meeting review. Based on their review of patients with available safety data, PDS0101 in combination with KEYTRUDA® continues to appear safe and well tolerated. Specifically, there were no drug discontinuations related to toxicity as of the DMC review. In addition, there were no Grade 3 or greater treatment-related adverse events attributed to the combination. The DMC recommended continuing the trial with no modifications.
“The safety profile of PDS0101 in combination with KEYTRUDA® was consistent with previously reported studies of KEYTRUDA® alone.” mentioned Dr. Lauren V. Wood, Chief Medical Officer of PDS Biotech. “The safety data in patients with recurrent or metastatic HPV16-positive head and neck cancer continues to appear to be well tolerated. We look forward to evaluating this further in the VERSATILE-002 trial.”
VERSATILE-002 enrollment has progressed to Stage 2 for the checkpoint inhibitor (CPI) naive cohort and is ongoing in Stage 1 for the CPI refractory cohort. The DMC is comprised of an independent group of clinical and scientific leaders in the field of immuno-oncology and is responsible for reviewing and evaluating patient safety and efficacy data in the Phase 2 VERSATILE-002 trial.
