Study of PDS0101 and Pembrolizumab Combination I/O in Subjects With HPV16 + Recurrent and/or Metastatic HNSCC
VERSATILE-002 is a Phase 2, open-label, multicenter study of the efficacy and safety of PDS0101 administered in combination with pembrolizumab in the first line treatment of adults with HPV16 and PD-L1 positive recurrent or metastatic head and neck squamous cell carcinoma (HNSCC).
A Phase II, Open-Label, Multi-Center Study of PDS0101 and Pembrolizumab (KEYTRUDA®) Combination Immunotherapy as a First Line Treatment in Subjects With Recurrent and/or Metastatic HNSCC and High-Risk HPV16 Infection
PDS0101 is a novel T-cell 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.

- For female subjects defined as Women of childbearing potential (WOCBP) a negative serum pregnancy test (β-human chorionic gonadotropin) must be obtained within 14 days prior to Day 1. Women who are surgically sterile or at least 2 years postmenopausal do not require pregnancy testing.
- Male subjects of childbearing potential must agree to use an effective method of contraception starting with the first dose of study therapy through 120 days after the last dose of study therapy.

- Pregnancy Exclusion: A female subject defined as a WOCBP who has a positive serum pregnancy test (e.g. within 14 days) prior to treatment.
- Has received prior therapy with an anti-PD-1, anti-PD- L1, or anti-PD-L2 agent with an agent directed to another stimulatory or co-inhibitory T-cell receptor (e.g. CTLA-4, OX40, CD137) and was discontinued from that treatment due to a Grade 3 or higher AE.
- Has received prior systemic anti-cancer therapy including investigational agents within 30 days prior to treatment.
Note: Subjects must have recovered from all AEs due to previous therapies to <Grade 1 or baseline. Subjects with <Grade 2 neuropathy and <Grade 2 alopecia are an exception to this criterion and may qualify for therapy.
Note: If participant received major surgery, they must have recovered adequately from the toxicity and/or complications from the intervention prior to starting treatment.
- Has received prior radiotherapy within 2 weeks of start of study treatment.
