Radiation plus immunotherapy: new hope for head and neck cancer?

NCT ID NCT03386357

First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This phase 2 trial tested whether adding radiotherapy to the immunotherapy drug pembrolizumab (Keytruda) helps shrink tumors in people with metastatic head and neck cancer that has spread. The study planned to enroll 115 participants, but was terminated early. Researchers measured tumor response using standard criteria. The goal was to see if the combination works better than pembrolizumab alone.
