Spots Global Cancer Trial Database for Safety and Efficacy of VB10.16 and Pembrolizumab in Patients With Head-Neck Squamous Cell Carcinoma

Study Description

Brief Summary: This is a multi-center study in patients with un-resectable Recurrent or Metastatic HPV16-positive Head and Neck Squamous Cell Carcinoma (HNSCC). The trial is designed to investigate VB10.16, an investigational therapeutic DNA vaccine in combination with another medicine, pembrolizumab, which is the standard of care for patients with previously untreated metastatic or resectable recurrent PD-L1 positive HNSCC. The study is divided in 2 parts: a phase 1, dose escalation part, testing 3 different doses of VB10.16 in combination with a standard fixed dose of pembrolizumab. The goal of this part is to evaluate the safety and tolerability of the combined treatment and to decide on the dose of VB10.16 to be used in the second part of the trial. In the second part of the trial, a phase 2a, dose expansion part, participants will receive either the highest safe dose of VB10.16 from part 1 or the 3 mg dose both in combination with pembrolizumab. The dose given to each participant will be decided in random. The trial is designed to define the optimal dose of VB10.16 in combination with pembrolizumab for future clinical studies based on the safety, tolerability and anti-tumor effect data generated.

Detailed Description: This phase 1/2a, open-label, dose-finding trial is designed to evaluate the safety, tolerability, immunogenicity, and anti-tumor activity of VB10.16 immunotherapy in patients with HPV16-positive R/M HNSCC whose tumors express PDL1 (CPS ≥ 1) and who are eligible for pembrolizumab monotherapy as standard of care. The trial is designed to determine the biological optimal dose (BOD) of VB10.16 in combination with a fixed dose of pembrolizumab based on the totality of data (i.e., safety, tolerability, anti-tumor activity, and HPV16 E6/E7specific cellular immune response). The trial consists of 2 consecutive phases with separate patient groups in a seamless trial design: a dose escalation phase (phase 1) and a dose expansion phase (phase 2a). After completing 48 weeks of combination treatment, patients can either continue pembrolizumab treatment with 200 mg Q3W administration or change to 400 mg Q6W administration at the discretion of the investigator and after consultation with the Sponsor.
