Antihistamine plus immunotherapy: a new hope for lung cancer patients?

NCT ID NCT07358689

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This Phase 2 trial tests whether adding the antihistamine diphenhydramine to the immunotherapy drug toripalimab and standard chemotherapy helps shrink tumors more effectively in people with operable non-small cell lung cancer. About 120 participants will receive either the combination or just toripalimab plus chemo before and after surgery. The main goal is to see how many patients have no cancer cells left in their removed tumor tissue.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
Toripalimab (a PD-1 inhibitor) and diphenhydramine (an antihistamine) plus platinum-based chemotherapy
What this could lead to
If successful, this could point toward a more effective pre-surgery treatment for lung cancer that helps shrink tumors more completely.
What could go wrong
This is an early Phase 2 trial with only 120 participants, so results may not apply to all patients. Adding diphenhydramine could also increase side effects without clear benefit.
