PDS Biotech Provides Recruitment update for National Cancer Institute-Led Phase 2 Clinical Trial of PDS0101-Based Combination

Institutional Review Board (IRB) approval has been obtained and clinical trial recruitment resumes

FLORHAM PARK, N.J., Dec. 06, 2021 (GLOBE NEWSWIRE) — PDS Biotechnology Corporation (Nasdaq: PDSB), a clinical-stage immunotherapy company developing novel cancer therapies based on the Company’s proprietary Versamune® T-cell activating technology, today announced the reopening of recruitment in the National Cancer Institute (NCI)-led Phase 2 clinical trial (NCT04287868) evaluating PDS0101 (Versamune®-HPV16) in combination with two investigational immune-modulating agents in advanced HPV cancers.

The suspension of recruitment was administrative in nature and was unrelated to any specific safety or efficacy concerns associated with the triple combination being studied. As a result, during the recruitment suspension, patients already enrolled in the study continued to receive scheduled treatment. The timing of clinical results from this trial is not expected to be affected by the pause in recruitment of new patients.

The trial is evaluating the novel triple combination in two groups of patients. Firstly, in second line treatment of recurrent or metastatic HPV-positive cancers including anal, cervical, head and neck, penile, vaginal, and vulvar cancers in patients who are naïve to checkpoint inhibitors and have not responded to at least one standard of care therapy. Secondly in third line treatment of the above recurrent or metastatic HPV-positive cancers in patients who have not responded to at least two standard of care therapies including checkpoint inhibitor treatment.

“We are pleased that the NCI, part of the National Institutes of Health, quickly obtained IRB approval to resume recruitment in this important trial. We believe the interim data demonstrated that this combination has the potential to significantly improve clinical outcomes for patients with advanced, refractory HPV16-positive cancers who have limited treatment options. Our approach of treating multiple types of cancer based on their molecular profiles rather than tissue location, may have the potential to provide safe Versamune®-based treatment options to an expanded population of patients suffering from multiple types of cancer and at different stages of disease,” said Dr. Lauren V. Wood, PDS Biotech’s Chief Medical Officer.

For patients interested in enrolling in this clinical study, please call NCI’s toll-free number 1-800-4-Cancer (1-800-422-6237) (TTY: 1-800-332-8615), email NCIMO_Referrals@mail.nih.gov, and/or visit the website: https://trials.cancer.gov.

About PDS0101

PDS Biotech’s lead candidate, PDS0101, combines the utility of the Versamune® platform with targeted antigens in HPV16-expressing cancers. In partnership with Merck & Co., PDS Biotech is evaluating a combination of PDS0101 and KEYTRUDA® in a Phase 2 study (NCT04260126) 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. PDS Biotech is also conducting a Phase 2 clinical study in both second- and third-line treatment of multiple advanced HPV-associated cancers 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.
