New combo therapy aims to outsmart 'Cold' rectal tumors

NCT ID NCT07026422

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

Summary

This Phase II trial tests whether adding a dual immunotherapy drug (iparomlimab/tuvonralimab) to standard chemoradiotherapy can improve outcomes for patients with locally advanced rectal cancer that has a specific genetic profile (pMMR/MSS), which usually does not respond to immunotherapy alone. The study plans to enroll 54 participants and will measure the rate of complete tumor disappearance. The goal is to see if this combination can turn 'immune-cold' tumors into 'hot' ones that respond better to treatment.

What this could mean

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

Active substance

iparomlimab/tuvonralimab (a dual immunotherapy drug) combined with chemoradiotherapy

What this could lead to

If successful, this could offer a new treatment option for patients with a common type of rectal cancer that typically does not respond well to immunotherapy alone.

What could go wrong

This is an early, small Phase II trial with only 54 participants, so results may not apply broadly. The combination therapy may cause side effects from both immunotherapy and chemoradiotherapy, and it is not yet known if it will improve long-term outcomes.
