On July 25, 2023 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 T cell activating platforms, reported that an abstract detailing immune response data from the VERSATILE-002 Phase 2 clinical trial investigating PDS0101 in combination with Merck’s anti-PD-1 therapy, KEYTRUDA (pembrolizumab), in patients with unresectable, recurrent or metastatic human papillomavirus (HPV)16-positive head and neck cancer has been accepted for presentation at the European Society for Medical Oncology Congress 2023 (ESMO Congress 2023) (Press release, PDS Biotechnology, JUL 25, 2023, View Source [SID1234633416]). ESMO (Free ESMO Whitepaper) Congress 2023 is being held October 20-24, 2023 in Madrid.

The abstract, titled, "Polyfunctional HPV16-Specific T cell responses in subjects receiving PDS0101 and pembrolizumab combination treatment for recurrent/metastatic HPV16-positive head and neck squamous cell carcinoma (HNSCC)," reports on the ability of PDS0101 in combination with KEYTRUDA to induce the right type of HPV16-specific multifunctional T cell responses in the treatment of advanced HPV16-positive head and neck cancer. PDS0101 is designed to stimulate a potent targeted T cell attack against HPV16-positive cancers. The immunological clinical data demonstrates the immunotherapy’s potential to generate clinically-relevant multifunctional HPV16-targeted CD8 and CD4 T cells with minimal toxicity in advanced head and neck cancer patients.
"We are pleased to present biomarker data from the VERSATILE-002 clinical trial among a gathering of the world’s leading members of the clinical and scientific oncology community at ESMO (Free ESMO Whitepaper) Congress 2023," stated Lauren V. Wood, M.D., PDS Biotech’s Chief Medical Officer and a co-author of the study. "The incidence of HPV-positive head and neck cancers is growing rapidly, and there is currently a lack of effective targeted therapies to address this population. To date, multiple studies in early-stage and advanced cancer patients have demonstrated the ability of PDS0101 to induce high levels of active and potent HPV16-specific CD4 and CD8 multifunctional T cells, as well as long-lasting memory CD8 T cells, substantiating the potential for PDS0101 combined with KEYTRUDA to expand the range of treatments addressing HPV16-positive head and neck cancers."

About PDS0101
PDS0101, PDS Biotech’s lead candidate, is a novel investigational human papillomavirus (HPV)-targeted immunotherapy that stimulates a potent targeted T cell attack against HPV-positive cancers. PDS0101 is given by subcutaneous injection alone or in combination with other immunotherapies and cancer treatments. In a Phase 1 study of PDS0101 in monotherapy, the treatment demonstrated the ability to generate multifunctional HPV16-targeted CD8 and CD4 T cells with minimal toxicity. Interim data suggests PDS0101 generates clinically effective immune responses and the combination of PDS0101with other treatments can demonstrate significant disease control by reducing or shrinking tumors, delaying disease progression, and/or prolonging survival. The combination of PDS0101 with other treatments does not appear to compound the toxicity of other agents.
About VERSATILE-002
VERSATILE-002 is a single-arm Phase 2 trial evaluating the safety and efficacy of PDS0101, an HPV16-targeted investigational T cell-activating immunotherapy that leverages PDS Biotech’s proprietary Versamune technology, in combination with Merck’s anti-PD-1 therapy, KEYTRUDA (pembrolizumab). The combination is being evaluated in immune checkpoint inhibitor (ICI)-naïve and ICI-refractory patients with recurrent/metastatic HPV16-positive head and neck squamous cell carcinoma (HNSCC) and was granted Fast Track designation by the Food and Drug Administration in June 2022.
Interim efficacy and safety data will be presented at the 2023 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting for ICI-naïve patients. Preliminary data from the first 34 patients demonstrated a 12-month overall survival rate of 87% and median progression free survival of 10.4 months. No Grade 4 or higher treatment related adverse events were observed.
