New cocktail approach aims to wipe out High-Risk rectal cancer without surgery

NCT ID NCT06908031

First seen Jul 01, 2026 · Last updated Jul 01, 2026

Summary

This phase 2 trial tests a powerful mix of short-course radiation, chemotherapy (mFOLFOX6), an immunotherapy (PD-1 antibody), and a targeted drug (cetuximab or bevacizumab, depending on genetic markers) in people with high-risk rectal cancer that is mismatch repair proficient (pMMR) and microsatellite stable (MSS). The goal is to see if this combination can make the tumor disappear completely (pathological complete response). The study enrolls 49 adults aged 18-75 with tumors within 10 cm of the anal verge.

What this could mean

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

Active substance

Short-course radiotherapy, mFOLFOX6 chemotherapy, PD-1 antibody, cetuximab (for RAS/BRAF wild-type), bevacizumab (for RAS/BRAF mutant)

What this could lead to

If successful, this combination could offer a more effective, non-surgical treatment path for high-risk rectal cancer, potentially increasing the chance of a complete response.

What could go wrong

This is an early-phase trial with only 49 participants, so results may not apply to all patients. Combining multiple therapies raises the risk of severe side effects.
