First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 2 times

Summary

This phase 3 trial is testing whether adding the immunotherapy drug AK104 (cadonilimab) before and after surgery can improve outcomes for people with a specific type of colon cancer (MSI-H/dMMR). About 386 participants will be randomly assigned to receive either AK104 plus standard chemotherapy or chemotherapy alone. The main goals are to see if the cancer disappears completely after treatment and if it delays the cancer from coming back.

What this could mean

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

Active substance

Cadonilimab (AK104), a drug that helps the immune system fight cancer, plus standard chemotherapy drugs (oxaliplatin, capecitabine, 5-fluorouracil, calcium folinate)

What this could lead to

If this works, it could offer a more effective treatment option for people with a specific type of colon cancer, potentially reducing the chance of cancer coming back after surgery.

What could go wrong

This is an early-phase 3 trial, so results are not yet known. The new drug may not work better than standard chemo, and it could cause side effects like immune-related inflammation.
