Dr. Frank Bedu-Addo, PDS Biotechnology’s President and Chief Executive Officer, said: "The award of this patent is a significant milestone for PDS as it provides further protections for our Versamune® platform technology and pipeline of Versamune®–powered therapeutic candidates, including our lead candidate, PDS0101. The patent adds to our robust portfolio of exclusively-owned international patents that cover the compositions and use of cationic lipids to activate key immunological pathways that facilitate T-cell priming and activation of antigen specific CD8+ T-cells while also reducing the population of immune suppressive regulatory T-cells. A major limitation of T-cell activating immunotherapies in the treatment of cancer is the need to overcome the tumor’s immune-suppressive environment. However, we believe that through our work with the National Cancer Institute we have received additional validation for the use of cationic lipids to activate key immunological signaling pathways that are essential to prime the right phenotype of tumor targeting T-cells in-vivo, while simultaneously making the tumor cells much more susceptible to killing by the primed T-cells.”
A portion of the work leading to this invention was carried out with support from the United States Government provided under the National Institutes of Health CRADA No. 2644. Therefore, the United States Government has certain rights in and to the present invention.
About the Versamune® Cationic Lipid Platform Technology
Versamune® is a proprietary, clinical stage, synthetic lipid-based immunotherapy platform. PDS Biotechnology’s pipeline of Versamune®-based products, which are administered by subcutaneous injection, provides strong activation of type I interferon genes. The Versamune® mechanism of action also involves effective presentation of tumor antigens via the MHC Class I and Class II pathways. These mechanisms together promote strong in-vivo induction of polyfunctional tumor-targeting CD8+ T-cells. This result, as well as a high degree of safety, was confirmed in the PDS0101 monotherapy Phase 1/2a human clinical trial.
Versamune®-based immunotherapies have been demonstrated to alter the tumor micro-environment in preclinical mechanism of action studies, thus further enhancing the ability of Versamune®-induced T-cells to effectively kill tumor cells. Versamune® is now being applied to the development of multiple clinical-stage cancer products, including those intended to address both early and late-stage cancer indications as monotherapies, as well as combinations with other successful immuno-oncology approaches such as checkpoint inhibitors.
About PDS Biotechnology
PDS Biotechnology is a clinical stage immuno-oncology company with a growing pipeline of clinical-stage immunotherapies to treat various early-stage and late-stage cancers, including head and neck cancer, cervical, anal, prostate, breast and other cancers.
PDS Biotechnology’s lead product candidate, PDS0101 (Versamune®-HPV) is a proprietary clinical stage immunotherapeutic administered by subcutaneous injection being developed to treat HPV-associated cancers such as head and neck cancers and anal cancers, both of which are widely reported to be increasing in frequency over the last decade, as well as cervical, penile, vaginal and vulvar cancers and their pre-cancerous conditions. In a human Phase 1/2a clinical study, PDS0101 monotherapy demonstrated potent in-vivo induction of the critical phenotype of tumor-attacking killer (CD8) T-cells, and induction of memory T-cells. No dose-limiting toxicities were observed in this study, suggesting potential for a rare combination of potency and safety among immune-oncology therapeutics.
