About PDS Biotechnology

PDS Biotech is a clinical-stage immunotherapy company developing a growing pipeline of novel cancer therapies based on the Company’s proprietary Versamune^® T-cell activating technology platform. Our Versamune^®-based products overcome the limitations of current immunotherapy by inducing in vivo, large quantities of high-quality, highly potent polyfunctional tumor specific CD4+ helper and CD8+ killer T-cells. PDS Biotech has developed multiple therapies, based on combinations of Versamune^® and disease-specific antigens, designed to train the immune system to better recognize diseased cells and effectively attack and destroy them. Our immuno-oncology product candidates are initially being studied in combination therapy to potentially enhance efficacy without compounding toxicity across a range of cancer types. The company’s lead investigational cancer immunotherapy product PDS0101 is currently in Phase 2 clinical studies in HPV-associated cancers. The company’s pipeline products address various cancers including breast, colon, lung, prostate and ovarian cancers.

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. PDS Biotech is also conducting two additional Phase 2 studies in advanced HPV-associated cancers and advanced localized cervical cancer with the National Cancer Institute (NCI) and The University of Texas MD Anderson Cancer Center, respectively.

About PDS0102

PDS0102 combines the utility of the Versamune^® platform with the proprietary T-cell receptor gamma alternate reading frame protein (TARP), a tumor antigen identified by the National Cancer Institute (NCI) which is strongly associated with prostate cancer, breast cancer and AML. The product is in late-stage clinical development and anticipated to enter human clinical trials in 2022.

About PDS0103

PDS0103 combines the utility of the Versamune^® platform with novel and proprietary highly immunogenic agonist epitopes of mucin-1 (MUC1) oncogenic C-terminal region. MUC1 is highly expressed in multiple tumor types and has been shown to be associated with drug resistance and poor disease prognosis. The product is in late-stage clinical development as part of a collaborative research and development agreement with the National Cancer Institute and anticipated to enter human clinical trials in 2022.
