Current Partners


PDS has a clinical trial collaboration agreement with Merck to evaluate the combination of PDS’s PDS0101 with Merck’s anti-PD-1 therapy, KEYTRUDA® (pembrolizumab), in a Phase 2 clinical trial. This trial will evaluate the safety and efficacy of the PDS0101-KEYTRUDA®combination in patients with recurrent or metastatic head and neck cancer and high-risk human papillomavirus-16 (HPV16) infection after failure with platinum-based chemotherapy.


PDS has a Cooperative Research and Development Agreement (CRADA) with the National Cancer Institute (NCI), an Institute of the U.S. National Institutes of Health. Under CRADA03039, PDS and NCI are co-developing several immunotherapies in upcoming Phase 2 clinical trials over the 2018–2020 period, utilizing combinations of Versamune® with NCI- and PDS-sourced tumor-related proteins or their fragments recognized by the immune system (antigens) in prostate, breast, and HPV-related cancers.

The currently confirmed CRADA03039-sponsored clinical trials include:

  • PDS0101: Phase 2b clinical trial in pre-anal (Anal Intraepithelial Neoplasia, or AIN2/3) and pre-cervical (Cervical Intraepithelial Neoplasia, or CIN2/3) patients who are also HIV-positive.
  • PDS0102: Phase 2b clinical trial in late-stage prostate cancer (D0) patients at risk of biochemical recurrence without radiographically measurable disease.
