PDS Biotech to Host Key Opinion Leader Event to Discuss Positive, Updated Data from Phase 2 VERSATILE-002 Clinical Trial with Versamune® HPV in Combination with KEYTRUDA® in Recurrent or Metastatic Head and Neck Cancer

Company to Host Key Opinion Leader Event on May 8 at 1:30pm ET to Discuss Updated Results of VERSATILE-002, Unmet Treatment Needs in Advanced Head and Neck Cancer and planned Triple Combination Trial

PRINCETON, N.J., April 23, 2024 (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 and the development of infectious disease vaccines, today announced a Key Opinion Leader (“KOL”) Event to discuss positive, updated data from its VERSATILE-002 Phase 2 clinical trial with Versamune^® HPV in combination with KEYTRUDA^® (pembrolizumab) () and next steps for Versamune^® HPV and PDS01ADC. The new data cut-off from VERSATILE-002 clinical trial remains consistent with the update provided by PDS Biotech in October of 2023.

The KOL event will take place on Wednesday, May 8, 2024, at 1:30 pm ET and panel participants will include:

• Dr. Jared Weiss, M.D., Section Chief of Thoracic and Head/Neck Oncology, Professor of Medicine at University of North Carolina, and Principal Investigator of the VERSATILE-002 clinical trial who will present and discuss the trial results
• Dr. Robert Haddad, M.D., Professor of Medicine, Harvard Medical School and Dana-Farber Cancer Institute who will discuss the unmet need in HPV-positive head and neck squamous cell cancer (“HNSCC")

The VERSATILE-002 trial is evaluating Versamune^® HPV (formerly PDS0101) in combination with the immune checkpoint inhibitor (“ICI”) pembrolizumab in patients with unresectable, recurrent, or metastatic HPV16-positive HNSCC. The topline results to be discussed at the upcoming event are based on analysis of the most recent data cut-off.

“Approximately 20% of HPV-related patients with HNSCC will develop recurrent, incurable disease,” said Dr. Weiss. “HPV-related HNSCC that is recurrent or metastatic is a devastating, difficult-to-treat cancer, and a majority of patients do not respond to current treatments, and therefore have a relatively short survival. We believe that the data warrant further investigation in a randomized controlled clinical trial, and we are hopeful about the potential that the unique combination including Versamune^® HPV and the IL-12 fused antibody drug conjugate PDS01ADC may represent in the treatment of HPV-related HNSCC.”

About PDS Biotechnology

PDS Biotechnology is a late-stage immunotherapy company focused on transforming how the immune system targets and kills cancers and the development of infectious disease vaccines. The Company plans to initiate a pivotal clinical trial in 2024 to advance its lead program in advanced head and neck squamous cell cancers (HNSCC). PDS Biotech’s lead program is a proprietary dual-acting combination of IL-12 fused antibody drug conjugate (ADC) PDS01ADC and T-cell activator Versamune^® HPV in regimen with a standard-of-care immune checkpoint inhibitor. Proof-of-concept long-term data have shown positive survival results and tumor shrinkage with this combination and indicate favorable tolerability.

With a novel investigational “inside-outside” mechanism, the PDS01ADC and Versamune^® HPV immunotherapy has shown compelling results with potential to successfully disrupt a tumor’s inside defenses, while also generating potent, targeted killer T-cells to attack the tumor from the outside. Robust data from more than 350 patients, as well as ongoing clinical trials across multiple tumor types and standard treatment regimens, have validated both platforms and point to potential broad utility.

Our Infectimune^® based vaccines have demonstrated the potential to induce not only robust and durable neutralizing antibody responses, but also powerful T-cell responses, including long-lasting memory T-cell responses in pre-clinical studies to date. For more information, please visit
