Triple therapy aims to shrink rectal tumors without surgery

NCT ID NCT07154316

First seen Jun 26, 2026 · Last updated Jun 26, 2026

Summary

This phase II trial tests whether adding immunotherapy and a COX-2 inhibitor to standard chemoradiotherapy can improve complete remission rates in people with locally advanced rectal cancer that is microsatellite stable (MSS). About 138 participants will receive either long-course or short-course radiation plus the drug combo. The goal is to see if the tumor disappears completely, potentially allowing patients to avoid surgery and keep their rectum.

What this could mean

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

Active substance

capecitabine, oxaliplatin, serplulimab, celecoxib, radiation therapy

What this could lead to

If successful, this combination could offer a more effective, organ-sparing treatment for a common type of rectal cancer, potentially avoiding permanent colostomy.

What could go wrong

This is a mid-stage trial with only 138 participants, so results may not apply to all patients. Adding multiple drugs also raises the risk of serious side effects.
