New combo therapy aims to shrink rare melanomas before surgery

NCT ID NCT05546827

First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study is testing whether giving radiation therapy along with immunotherapy before surgery can improve outcomes for people with sinonasal or anorectal mucosal melanoma, two rare and aggressive cancers. About 40 participants will receive combination immunotherapy (such as ipilimumab with nivolumab) followed by radiation, then surgical removal of the tumor. The main goal is to see how many patients have a significant reduction or disappearance of the tumor after this pre-operative treatment.

What this could mean

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

Active substance
combination immunotherapy (ipilimumab and nivolumab or nivolumab and relatlimab) and radiation therapy
What this could lead to
If successful, this approach could lead to better tumor control and fewer recurrences for patients with these rare and hard-to-treat melanomas.
What could go wrong
This is a small Phase 2 trial with only 40 participants, so results may not apply broadly. The combination of radiation and immunotherapy can cause significant side effects.
