Received guidance on registrational path for combination in recurrent/metastatic, immune checkpoint inhibitor refractory head and neck cancer
FLORHAM PARK, N.J., Feb. 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 successful completion of a Type B meeting with the U.S. Food and Drug Administration (FDA) for a combination therapy of PDS0101, PDS01ADC and an FDA-approved immune checkpoint inhibitor (ICI) for the treatment of recurrent/metastatic human papilloma virus (HPV)-positive, ICI refractory head and neck cancer. Head and neck cancers are the most common of all HPV-positive cancers and the number of cases is growing rapidly, according to the National Cancer Institute (NCI), one of the National Institutes of Health (NIH). There remains a critical unmet medical need to develop new treatment options for patients who have failed treatment with ICIs.
In recent interactions with the FDA, PDS Biotech has confirmed the required contents of the study design for a potential registrational trial of the combination of PDS0101, PDS01ADC and a commercial immune checkpoint inhibitor. PDS0101, PDS Biotech’s lead candidate, is a Versamune® based investigational immunotherapy designed to stimulate a potent targeted T cell attack against HPV16-positive cancers. PDS01ADC is a novel, proprietary investigational tumor-targeting fusion protein of Interleukin 12 (IL-12) that enhances the proliferation, potency and longevity of T cells in the tumor microenvironment, and is designed to overcome tumor immune suppression utilizing a different mechanism from checkpoint inhibitors. The combination of Versamune® and IL-12 is patented by PDS Biotech. In a National Cancer Institute (NCI)-led clinical trial in advanced HPV-positive ICI refractory patients, the combination of PDS0101 and PDS01ADC administered with an investigational bi-functional ICI resulted in a median overall survival of 21 months, which compares favorably to the historical median survival of 3-4 months.
“We are pleased with the guidance from the FDA on key elements of a study design to progress the development of our assets, PDS0101 and PDS01ADC, in combination with a commercial immune checkpoint inhibitor,” said Dr. Frank Bedu-Addo, Chief Executive Officer of PDS Biotech. “This concurrence to substitute an FDA-approved commercially available ICI for the investigational agent studied in the NCI trial simplifies the regulatory pathway for this triple combination.”
Dr. Bedu-Addo continued, “Versamune® based investigational immunotherapies in combination with PDS01ADC represent a potentially transformative treatment approach for recurrent/metastatic, ICI refractory cancer patients with poor survival prognosis. We remain committed to addressing unmet needs in cancer with more effective immunotherapy.”
About PDS0101
PDS0101, PDS Biotech’s lead candidate, is a novel investigational human papilloma virus (HPV)-targeted immunotherapy that stimulates a potent targeted T cell attack against HPV-positive cancers. PDS0101 is given by a simple subcutaneous injection in combination with other immunotherapies and cancer treatments. Interim data suggests PDS0101 generates clinically effective immune responses, and the combination of PDS0101 with other treatments can demonstrate significant disease control by 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 PDS01ADC
PDS01ADC is a novel investigational fusion protein of a tumor-targeting antibody and Interleukin 12 (IL-12) that enhances the proliferation, potency and longevity of T cells in the tumor microenvironment. Together with Versamune® based immunotherapies PDS01ADC works synergistically to promote a targeted T cell attack against cancers. PDS01ADC is given by a simple subcutaneous injection. Clinical data suggest the addition of PDS01ADC to Versamune® based immunotherapies can demonstrate significant disease control by shrinking tumors and/or prolonging survival in recurrent/metastatic cancers with poor survival prognosis.
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®, PDS01ADC, and Infectimune™ T cell-activating platforms. We believe our targeted Versamune® and PDS01ADC based candidates 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 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.
