Study examines best sequence of treatments for advanced bowel cancer
NCT ID NCT06137170
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at data from 121 people with metastatic colorectal cancer who received two approved treatments—regorafenib and TAS (with or without bevacizumab)—in different orders. Researchers want to see which sequence works better and how long patients live. Since this is an observational study using existing health records, no new treatments or visits are involved.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- regorafenib, TAS (trifluridine/tipiracil), bevacizumab
- What this could lead to
- If successful, this study could help doctors choose the best order of treatments for people with advanced colorectal cancer, potentially improving survival.
- What could go wrong
- This is an observational study using existing data, so it cannot prove cause and effect. Results may not apply to all patients or settings.

Who is studied
This is a retrospective cohort study of patients aged ≥18 years at the diagnosis of mCRC in real world clinical practice who received sequential treatment with regorafenib followed by TAS (with or without Bevacizumab, R-TAS±BEV) and vice versa (TAS±BEV-R) from January 1, 2019 to December 31, 2022 (inclusion period), or the latest available date that allows at least 3 months of follow-up, at multiple clinical centers in France, Italy, and Spain. The study will use longitudinal patients and clinical data recorded at the centers.
