Intervention model description: A modified randomized phase 2 selection ('pick-the-winner') design with a margin of practical equivalence will be implemented to monitor efficacy of the two individual arms, and to decide which of the two arms that may be continued further based on the primary endpoint of confirmed ORR.
Primary purpose: TREATMENT

Brief summary: 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.

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.

Eligibility criteria: Key Inclusion Criteria:

1. Age ≥18 years at ICF signature date.
2. Persistent recurrent or metastatic (R/M) (stage IVB) PD-L1 positive cervical cancer with squamous cell, adenocarcinoma or adenosquamous histology with confirmed disease progression during or after treatment with 1st line systemic standard of care pembrolizumab + platinum-containing chemotherapy +/- bevacizumab

   1. Participants should have received at least 4 cycles of pembrolizumab.
   2. Planned treatment start should be within 12 weeks of documented radiographic disease progression.
   3. Participants should have received no more than 1 prior systemic anti-cancer treatment regimen for recurrent/metastatic cervical cancer (pembrolizumab + chemotherapy +/- bevacizumab).
3. PD-L1-positive tumor confirmed by Ventana SP263 clone (the Food and Drug Administration approved companion diagnostic test for atezolizumab in other indications), with tumor area positivity ≥5% in designated central laboratory
4. HPV16-positive tumor confirmed by nucleic acid amplification test in designated central laboratory
