FLORHAM PARK, N.J., Oct. 03, 2022 (GLOBE NEWSWIRE) -- PDS Biotechnology Corporation (Nasdaq: PDSB), a clinical-stage immunotherapy company developing a growing pipeline of targeted immunotherapies for cancer and infectious disease, today announced that it has successfully completed an End-of-Phase 2 meeting with the U.S. Food and Drug Administration (FDA) for PDS0101 in combination with Merck’s anti-PD-1 therapy, KEYTRUDA® (pembrolizumab) for the treatment of unresectable, recurrent/metastatic human papilloma virus (HPV) 16-positive head and neck squamous cell carcinoma (HNSCC). “We are very pleased with the guidance received from FDA on key elements of the clinical program that will support the submission of a Biologics License Application (BLA) for our lead asset PDS0101,” said Dr. Frank Bedu-Addo, Chief Executive Officer of PDS Biotech. “The interim safety and efficacy data we presented to the FDA has allowed us to move into a registrational trial ahead of our projected schedule. This, along with the recent capital raise, allows us to efficiently advance our clinical programs.” Earlier this year, the FDA granted Fast Track designation to the combination of PDS0101 and KEYTRUDA® (pembrolizumab) for the treatment of HPV16-positive HNSCC. The FDA’s Fast Track designation program is designed to aid in the development and to expedite the review of drug candidate applications that could potentially treat serious or life-threatening conditions. Treatments granted this designation are given the opportunity to have more frequent meetings and interactions with the FDA throughout the entire drug development and review process, with the goal of moving promising new drugs more rapidly through the process. Dr. Frank Bedu-Addo further commented, “PDS0101 represents a potentially transformative treatment approach for HPV16-positive HNSCC patients. We are committed to providing physicians and patients a possibly more effective and safer treatment option to address this debilitating and deadly disease.” 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® and Infectimune™ T cell-activating technology platforms. We believe our targeted Versamune® based candidates have the potential to overcome the limitations of current immunotherapy by inducing large quantities of high-quality, highly potent polyfunctional tumor specific CD4+ helper and CD8+ killer T cells. To date, our lead Versamune® clinical candidate, PDS0101, has demonstrated the ability to reduce 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. 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.

About PDS0101 PDS Biotech’s lead candidate, PDS0101, combines the utility of the Versamune® platform with targeted antigens in HPV-expressing cancers. In partnership with Merck & Co., PDS Biotech is evaluating a combination of PDS0101 and KEYTRUDA® in a Phase 2 study in first-line treatment of recurrent or metastatic head and neck cancer, and also in second line treatment of recurrent or metastatic head and neck cancer in patients who have failed prior checkpoint inhibitor therapy. A Phase 2 clinical study is also being conducted in both second- and third-line treatment of multiple advanced HPV-associated cancers in partnership with the National Cancer Institute (NCI). A third Phase 2 clinical trial in first line treatment of locally advanced cervical cancer is being performed with The University of Texas, MD Anderson Cancer Center. A final Phase 2 clinical trial of PDS0101 monotherapy in first line treatment of newly diagnosed patients HPV16+ head and neck cancer patients is being conducted at the Mayo Clinic. KEYTRUDA® is a registered trademark of Merck Sharp and Dohme LLC, a subsidiary of Merck & Co., Inc., Rahway, NJ, USA. 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 CPI-naïve and CPI-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. In June 2022, preliminary efficacy and safety data were presented at the American Society of Clinical Oncology (ASCO) Annual Meeting for CPI-naïve patients (PR link). 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%.
