First seen Jun 26, 2026 · Last updated Jul 16, 2026 · Updated 3 times
Summary
This early-phase trial tests whether adding axelopran—a drug that blocks opioid effects on the immune system—can help pembrolizumab (an immunotherapy) work better in people with advanced head and neck cancer who take opioids for pain. About 18 participants will receive both drugs and be monitored for safety and tumor response. The goal is to see if counteracting opioid-related immune suppression improves treatment outcomes.
