New chemo cocktail aims to stop colon Cancer's return
NCT ID NCT05179889
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This trial compares two chemotherapy combinations after surgery for people with high-risk stage III colon cancer. About 308 participants will receive either mFOLFIRINOX or the standard mFOLFOX6 for 12 cycles. The goal is to see if the stronger combo delays cancer recurrence and improves survival.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- chemotherapy (irinotecan, oxaliplatin, leucovorin, 5-FU)
- What this could lead to
- If successful, this could show that a stronger chemo combo (mFOLFIRINOX) helps prevent colon cancer from coming back after surgery better than the current standard.
- What could go wrong
- This is a mid-stage trial, so results are not yet proven. The stronger chemo may cause more side effects, and it may not improve survival or recurrence rates.
