Immunotherapy boosts standard treatment for rectal cancer?

NCT ID NCT03921684

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

Summary

This phase 2 trial tests whether adding the immunotherapy drug nivolumab (Opdivo) to standard chemoradiation and chemotherapy can improve outcomes for people with locally advanced rectal cancer. About 29 participants who have not had prior treatment will receive chemoradiation, then six cycles of chemo plus nivolumab, followed by surgery. The main goal is to see how many patients have no cancer left at the time of surgery.

What this could mean

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

Active substance

nivolumab (Opdivo) plus chemotherapy (capecitabine, oxaliplatin, leucovorin, fluorouracil) and radiation

What this could lead to

If successful, this combination could increase the chance of eliminating all cancer before surgery, potentially allowing some patients to avoid surgery altogether.

What could go wrong

This is a small, early-phase trial with only 29 participants, so results may not apply broadly. Adding immunotherapy to chemotherapy also raises the risk of immune-related side effects.
