FLORHAM PARK, N.J., April 27, 2023 (GLOBE NEWSWIRE) -- PDS Biotechnology Corporation (Nasdaq: PDSB), a clinical-stage immunotherapy company developing a growing pipeline of targeted immunotherapies for cancer and infectious disease, announced the presentation of updated data from the VERSATILE-002 study at the 2023 ASCO® Annual Meeting being held June 2-6 in Chicago. The abstract was also selected as one of the featured posters to be reviewed by an expert panel in the Head and Neck Cancer discussion session.
VERSATILE-002 is a Phase 2, open-label, multicenter study of the efficacy and safety of PDS0101 administered in combination with Merck’s (known as MSD outside the US and Canada) anti-PD-1 therapy, KEYTRUDA® (pembrolizumab), in adults with human papilloma virus (HPV)16 positive, unresectable recurrent or metastatic head and neck squamous cell carcinoma (HNSCC). VERSATILE-002 is investigating two patient populations of HPV16-positive head and neck cancer patients whose cancer has returned or spread. The first group, which is the focus of the ASCO poster presentation, has not been previously treated with an immune checkpoint inhibitor (ICI), also known as the ICI naïve cohort, and is PD-L1 positive, and the second group of patients has failed treatments including ICI therapy (ICI refractory).
“We are pleased to present updated data from the VERSATILE-002 clinical trial,” 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. The ASCO meeting provides an opportunity to share promising early data with the clinical and scientific community that shows how PDS0101 combined with KEYTRUDA® can potentially address this unmet medical need.”

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 in combination with other immunotherapies and cancer treatments. Phase 1 monotherapy data demonstrate that PDS0101 generates strong HPV-specific immune responses. Interim Phase 2 data suggest that the combination of PDS0101 with other treatments potentially demonstrates significant disease control by shrinking advanced and metastatic 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. Preliminary efficacy and safety data were presented at the 2022 American Society of Clinical Oncology (ASCO) Annual Meeting for ICI-naïve patients. Preliminary data from the first 19 patients demonstrated that 77% of the patients with available imaging (17 of 19) had either disease stabilization or tumor shrinkage. Additionally, the overall survival rate of these patients at 9-months was 87%.

About PDS Biotechnology
PDS Biotech is a clinical-stage immunotherapy company developing a growing pipeline of targeted cancer and infectious disease immunotherapies based on our proprietary Versamune®, Versamune® plus PDS0301, and Infectimune™ T cell-activating platforms. We believe our targeted immunotherapies have the potential to overcome the limitations of current immunotherapy approaches through the activation of the right type, quantity and potency of T cells. To date, our lead Versamune® clinical candidate, PDS0101, has demonstrated the ability to shrink tumors and stabilize disease in combination with approved and investigational therapeutics in patients with a broad range of HPV16-associated cancers in multiple Phase 2 clinical trials and will be advancing into a Phase 3 clinical trial in combination with KEYTRUDA® for the treatment of recurrent/metastatic HPV16-positive head and neck cancer in 2023. Our Infectimune™ based vaccines have also 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.
