New cocktail of drugs shows promise for Tough-to-Treat colorectal cancer
NCT ID NCT06967155
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This phase 2 trial is testing a combination of four drugs—irinotecan, dabrafenib, trametinib, and either cetuximab or panitumumab—as a second-line treatment for people with metastatic colorectal cancer that has a BRAF V600E mutation. The study aims to see how well this drug mix shrinks tumors and controls the disease. About 23 participants will be followed for up to three years to monitor response and 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
- Irinotecan, dabrafenib, trametinib, and cetuximab or panitumumab
- What this could lead to
- If successful, this could offer a new second-line treatment option for people with a specific type of advanced colorectal cancer that has a BRAF mutation.
- What could go wrong
- This is a small, early-phase trial with only 23 participants, so results may not apply to everyone. The drug combination can cause significant side effects, and it is not yet known if it will improve survival compared to existing treatments.

Absence of grade 2 or higher toxicity from previous line of treatment. 6. It is possible to include patients with MSI or dMMR if they have received first-line immune checkpoint therapy. 7. ECOG PS 0-1 Exclusion Criteria: 1. Participants having more than 2 lines of treatment (a progression of disease within 12 months of the completion of adjuvant and/or perioperative chemotherapy with oxaliplatin and fluoropyrimidines is acceptable). 2.
