Immunotherapy combo shows promise in Hard-to-Treat rectal cancer

NCT ID NCT07005570

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This phase 2 trial tests whether adding an immunotherapy drug (PD-1 antibody) and a blood vessel blocker (bevacizumab) to standard short-course radiotherapy and chemotherapy can improve outcomes for people with a common type of locally advanced rectal cancer (pMMR/MSS). About 86 participants will receive either the standard treatment or the enhanced combination. The main goal is to see if the tumor completely disappears before surgery, which could help some patients avoid surgery entirely.

What this could mean

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

Active substance

PD-1 monoclonal antibody and bevacizumab combined with chemotherapy (CAPOX regimen)

What this could lead to

If successful, this could improve the chance of complete tumor disappearance before surgery, potentially allowing some patients to avoid surgery altogether.

What could go wrong

This is a small, early-phase trial (86 participants) and the added immunotherapy may cause immune-related side effects. Results may not apply to all rectal cancer patients.
