PRINCETON, N.J., Oct. 30, 2025 (GLOBE NEWSWIRE) -- PDS Biotechnology Corporation (Nasdaq: PDSB) (“PDS Biotech” or the “Company”), a late-stage immunotherapy company focused on transforming how the immune system targets and kills cancers, today announced that the National Cancer Institute (NCI) will present new clinical data at the 2025 Society for Immunotherapy of Cancer (SITC) Annual Meeting, taking place in National Harbor, Maryland. The NCI will present three abstracts highlighting emerging clinical and translational findings from its novel investigational immunotherapy platforms, including the tumor-targeting IL-12 fused antibody drug conjugate (PDS01ADC) and PDS0101, its lead Phase 3 clinical stage HPV-targeted immunotherapy. Together, these abstract presentations reflect PDS Biotechnology’s continued focus on advancing differentiated immunotherapy candidates designed to engage both adaptive and innate immune responses against cancer.

“We look forward to sharing new data generated as part of the company’s ongoing collaboration with the NCI at SITC that further highlight the potential of our platforms to reshape how the immune system recognizes and eliminates cancer,” said Frank Bedu-Addo, Ph.D., CEO of PDS Biotechnology. “Our programs are built on a strong foundation of translational science and clinical collaboration, with the goal of developing immunotherapies that activate both adaptive and innate immune responses in a precise and targeted way. The presentations at SITC reflect our ongoing commitment to advancing innovative approaches that may ultimately improve outcomes for patients with difficult-to-treat cancers.”
