New cocktail aims to shrink tough colorectal tumors
NCT ID NCT06948448
First seen Jun 27, 2026 · Last updated Jul 17, 2026 · Updated 2 times
Summary
This Phase 2 trial tests whether adding an experimental drug (ONO-4578) and an immunotherapy (Opdivo) to standard chemotherapy and bevacizumab can shrink tumors better than standard care alone in people with advanced colorectal cancer that is not MSI-high and has PD-L1 expression. About 144 participants will receive one of two doses of the new combination. The main goals are to see how many patients respond and to monitor side effects.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- ONO-4578 (an experimental drug) combined with nivolumab (Opdivo), chemotherapy (mFOLFOX6), and bevacizumab
- What this could lead to
- If successful, this could offer a new first-line treatment option for people with a specific type of advanced colorectal cancer, potentially improving tumor shrinkage rates.
- What could go wrong
- This is an early Phase 2 trial with only 144 participants, so results may not apply to everyone. Adding more drugs also raises the risk of side effects.
