New drug cocktail shows promise for Tough-to-Treat colon cancer
NCT ID NCT05854498
First seen Jun 24, 2026 · Last updated Sep 16, 2026 · Updated 4 times
Summary
This study is testing whether a combination of three drugs—liposomal irinotecan, TAS102, and bevacizumab—can help people with metastatic colorectal cancer that has not responded to prior treatments. About 50 adults with mismatch repair proficient tumors will receive the drugs in cycles. The main goal is to see how long the cancer stays under control.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- liposomal irinotecan, TAS102, and bevacizumab
- What this could lead to
- If successful, this combination could offer a new treatment option for patients with metastatic colorectal cancer who have not responded to standard therapies.
- What could go wrong
- This is a small, early-phase trial with only 50 participants, so results may not apply broadly. The combination may cause serious side effects, and it is not yet known if it improves survival.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Patients must be ≥ 18 years of age * Eastern Cooperative Oncology Group (ECOG) performance must be 0 or 1. * Patients must have a histologically or cytologically confirmed diagnosis of colorectal adenocarcinoma and be metastatic or unresectable. * The cancer must be mismatch repair proficient. * Patients must have had prior treatment with 5-fluorouracil, oxaliplatin, irinotecan containing regimens. If RAS wild-type must have received prior anti-EGFR therapy with either cetuximab or panitumumab. If RAS wild-type and HER2 positive then must have had a prior HER2 targeted therapy. Exclusion Criteria: * Uncontrolled concurrent medical illness that would not allow for the completion of the planned therapy. * Patients whose cancers possess BRAF V600 mutations are excluded. * Patients must stop the use of strong inducers/inhibitors of CYP3A4 at least 2 weeks before initiating therapy. * Patients must not have mismatch repair deficient or microsatellite instability high cancers. * Patients must not have received prior TAS102.
