Triple threat: vaccine, immunotherapy, and Chemo-Radiation take on HPV head and neck cancer

NCT ID NCT04369937

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This phase 2 trial tested a new approach for people with intermediate-risk HPV-related head and neck cancer. Participants received an HPV-16 vaccine (ISA101b) plus the immunotherapy drug pembrolizumab alongside standard chemoradiation. The goal was to see if this combination could improve the chance of keeping the cancer from progressing. The study enrolled 18 patients and tracked how many were still cancer-free after two years, as well as any serious side effects.

Active substance

HPV-16 vaccine (ISA101b) plus pembrolizumab and cisplatin chemoradiotherapy

What this could lead to

If successful, this combination could improve the chance of keeping HPV-related head and neck cancer from coming back after standard treatment.

What could go wrong

This is a small, early-phase trial with only 18 participants, so results may not apply to everyone. Adding more drugs also raises the risk of serious side effects.
