First seen Apr 23, 2026 · Last updated Apr 30, 2026 · Updated 2 times

Summary

This study tests whether adding an experimental drug (GB1211) to the standard immunotherapy pembrolizumab can shrink tumors better than pembrolizumab alone. It includes about 92 adults with advanced melanoma or head and neck cancer that has spread or cannot be removed. Participants will receive either the combination or pembrolizumab with a placebo, and researchers will monitor tumor response and side effects.
