PDS Biotech Announces Data from IMMUNOCERV Phase 2 Trial Investigating PDS0101 and Chemoradiotherapy in Cervical Cancer to be Featured in Oral Presentation at the ASTRO 2023 Annual Meeting

Study evaluates the effect of combining PDS0101 with standard of care on levels of circulating HPV viral DNA in cervical cancer patients and impact on disease status and clearance

PRINCETON, N.J., Aug. 16, 2023 (GLOBE NEWSWIRE) — PDS Biotechnology Corporation (Nasdaq: PDSB) (PDS Biotech or the Company), 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, today announced that data from the IMMUNOCERV Phase 2 clinical trial investigating PDS0101 in combination with standard-of-care chemoradiotherapy (CRT) for the treatment of locally advanced cervical cancer will be featured in an oral presentation at the American Society for Radiation Oncology (ASTRO 2023) Annual Meeting. ASTRO 2023 is being held October 1-4, 2023, in San Diego, CA.

The abstract, titled “HPV Circulating Cell-Free DNA Kinetics in Cervical Cancer Patients Undergoing Definitive Chemoradiation,” will report on the levels of circulating HPV-positive cell-free DNA (HPV-cfDNA) in the blood of 47 cervical cancer patients during and after CRT treatment, including subjects in the IMMUNOCERV study who received PDS0101 in addition to CRT. The research is designed to evaluate the relationship between the levels of circulating HPV viral DNA and the extent of disease, clinical staging, and treatment response in patients with HPV-positive cervical cancer. The findings will be presented by Dr. Aaron Seo, MD, Ph.D., The University of Texas MD Anderson Cancer Center.

“We are pleased that PDS0101 is being evaluated in this cutting-edge approach to better understand the patients’ prognosis and the mechanism by which PDS0101 may impact clinical outcomes in cervical cancer, and we look forward to Dr. Seo’s presentation at ASTRO 2023,” stated Dr. Lauren V. Wood, Chief Medical Officer of PDS Biotech. “Examination of HPV-cfDNA in this larger cohort of patients will also provide additional insights to the IMMUNOCERV data presented at SITC 2022, which suggested that PDS0101 promotes the induction of multifunctional CD8 killer T cells that were associated with declines in circulating tumor DNA and 100% (9/9) clinical response with greater than 60% tumor shrinkage at mid-point evaluation in high-risk cervical cancer patients.”

The IMMUNOCERV Phase 2 study is investigating PDS0101 in combination with standard-of-care CRT in the treatment of patients with large tumors over 5 cm in size and/or cancer that has spread to the lymph nodes.

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 reduce and 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.

About Versamune^®

Versamune^® is a novel investigational T cell activating platform which effectively stimulates a precise immune system response to a cancer-specific protein. Versamune^® based investigational immunotherapies promote a potent targeted T cell attack against cancers expressing the protein. They are given by subcutaneous injection and can be combined with standard of care treatments. Clinical data suggest that Versamune^® based investigational immunotherapies, such as PDS0101, demonstrate meaningful disease control by reducing and shrinking tumors, delaying disease progression and/or prolonging survival. Versamune^® based immunotherapies have demonstrated minimal toxicity to date that may allow them to be safely combined with other treatments. We believe Versamune^® based investigational immunotherapies represent a transformative treatment approach for cancer patients to provide improved efficacy, safety and tolerability.

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 PDS0101 with 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.
