Pembrolizumab will be administered via IV Infusion followed by subcutaneous injections of PDS0101 five times throughout the course of the study. Pembrolizumab monotherapy will be administered every cycle there is not a combination treatment until disease progression or up to Cycle 35.

IV infusion of pembrolizumab 200 mg + two 0.5mL sub-cutaneous injections of PDS0101 administered on Cycle 1, 2, 3, 4 and 12. IV infusion of Pembrolizumab 200 mg monotherapy will be administered Cycles 5 - 11 and 13 - 35.

Pembrolizumab (KEYTRUDA®) and PDS0101

David T Schaaf, MD

VERSATILE-002 is a Phase 2, open-label, multicenter study of the efficacy and safety of PDS0101 administered in combination with pembrolizumab in adults with HPV16 and PD-L1 positive recurrent or metastatic head and neck squamous cell carcinoma (HNSCC).

PDS0101 is a novel T-cell HPV-specific immunotherapy delivered subcutaneously that has been shown to stimulate high levels of HPV16-specific CD8+ and CD4+ T cells within patients by activating multiple immune pathways. These HPV-specific T cells then target tumors such as head and neck, anal and cervical cancers that are caused by HPV infection. The number of HNSCC cases has been increasing steadily over the last 10-15 years and over 90% of HPV-positive head and neck cancers are HPV16 positive. Pembrolizumab has been shown to have efficacy against both HPV-positive and HPV-negative head and neck cancers. However, its effectiveness is more optimal in tumors that are PD-L1 positive and have evidence of immune cells within the tumor. We hypothesize that increasing tumor-targeting HPV-specific T-cells with PDS0101 will be associated with an increased response to pembrolizumab. This study will explore in a preliminary manner whether combination treatment with PDS0101 plus pembrolizumab will improve clinical efficacy over that seen with pembrolizumab alone in the KEYNOTE-048 study. Subjects will be enrolled into either the checkpoint inhibitor (CPI) naïve cohort or the CPI refractory cohort.

Study of PDS0101 and Pembrolizumab Combination I/O in Subjects With HPV16 + Recurrent and/or Metastatic HNSCC

A Phase II, Open-Label, Multi-Center Study of PDS0101 and Pembrolizumab (KEYTRUDA®) Combination Immunotherapy in Subjects With Recurrent and/or Metastatic HNSCC and High-Risk HPV16 Infection

Length of time that the subjects who demonstrated ORR at 9 months, continue to respond to treatment.

Using IsoPlexis Functional Proteomics at Days 85 (Cycle 5) and 253 (Cycle 13) compared to baseline.

Overall survival (OS) is defined as time from date of first dose until death from any cause. Those subjects who are still alive will be censored at their last known date of contact.

AE's will be summarized by severity using NCI CTCAE, version 50 (v.11.27.17) and by relationship to study treatment.
