FLORHAM PARK, N.J., April 27, 2022 (GLOBE NEWSWIRE) -- PDS Biotechnology Corporation (Nasdaq: PDSB), a clinical-stage immunotherapy company developing a growing pipeline of molecularly targeted cancer immunotherapies and infectious disease vaccines based on the Company’s proprietary Versamune^® and Infectimune™ T-cell activating technologies, today announced the titles of two abstracts accepted for poster presentations during the 2022 American Society of Clinical Oncology (ASCO) Annual Meeting being held from June 3-7, 2022.

Abstract # 6041 poster presentation summarizes updates to the preliminary efficacy and safety data from the PDS Biotechnology sponsored VERSATILE-002 Phase 2 clinical trial, which is studying PDS0101 in combination with Merck’s anti-PD-1 therapy KEYTRUDA^® (pembrolizumab) for the treatment of recurrent or metastatic HPV16-positive head and neck cancer. This trial is designed to treat both checkpoint inhibitor (CPI) naïve and refractory patients. PDS Biotech previously announced that the trial had achieved its preliminary efficacy milestone in the CPI naive arm earlier this year and presented detailed preliminary safety data at the 2022 Multidisciplinary Head and Neck Cancers Symposium.
