Efficacy and Safety of VB10.16 Alone or in Combination With Atezolizumab in Patients With Advanced Cervical Cancer.

A Two-Arm Randomized, Double-Blind, Placebo-Controlled Phase 2 Selection Trial to Evaluate the Efficacy and Safety of VB10.16 Alone or in Combination With Atezolizumab in Patients With HPV16-Positive, PD-L1-positive, Recurrent or Metastatic Cervical Cancer Who Are Refractory to Pembrolizumab With Chemotherapy With/Without Bevacizumab.

This is a multi-center study in patients with recurrent or metastatic HPV16-positive, PD-L1 positive cervical cancer who has progressed during or after treatment with the first-line standard of care (pembrolizumab with chemotherapy with/without bevacizumab).

The trial is designed to investigate VB10.16 alone or in combination with the immune checkpoint inhibitor, atezolizumab.

The trial consist of 2 parts: the first part which investigates VB10.16 + placebo versus VB10.16 + atezolizumab. Approximately 30 patients will be included in each group. The goal of this part is to evaluate which of the two treatments is the best.

The second part of the study will select the best treatment from part 1 and investigate the safety and efficacy of additional 70 patients.

Study Overview

• Status: Recruiting
• Conditions: Cervical Cancer; HPV-Related Malignancy; HPV-Related Cervical Carcinoma
• Intervention / Treatment: Biological: VB10.16; Drug: Placebo; Drug: Atezolizumab Injection [Tecentriq]

Detailed Description

This is a two-arm randomized, double-blind, placebo-controlled phase 2 selection trial to evaluate the efficacy and safety of VB10.16 alone or in combination with atezolizumab in patients with HPV16-positive, PD-L1-positive, recurrent or metastatic cervical cancer who are refractory to pembrolizumab with chemotherapy with/without bevacizumab. A selection design with a margin of practical equivalence will be implemented to monitor efficacy of the two experimental arms (VB10.16 + atezolizumab vs. VB10.16 + placebo).

The trial consist of 2 parts: the first part which investigates VB10.16 + placebo versus VB10.16 + atezolizumab. Approximately 30 patients will be included in each group. The goal of this part is to evaluate which of the two treatments is the superior.

The second part of the study will select the superior treatment from part 1 and investigate the safety and efficacy of additional 70 patients.
