New cocktail of cancer drugs tested for Tough-to-Treat colorectal cancer
NCT ID NCT03377361
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested a combination of nivolumab (Opdivo) and trametinib (Mekinist), with or without ipilimumab (Yervoy), in 325 people whose colorectal cancer had spread and had not responded to prior treatments. The main goals were to check safety and see if the drugs could shrink tumors. The trial has been completed, and results will help determine if this approach is worth further study.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- nivolumab (Opdivo), trametinib (Mekinist), ipilimumab (Yervoy), regorafenib
- What this could lead to
- If successful, this combination could offer a new treatment option for people with advanced colorectal cancer that has not responded to prior therapy.
- What could go wrong
- This was an early-phase trial (Phase 1/2) focused on safety and dosing, so it is not yet clear if the combination works better than existing treatments. Side effects from combining these drugs may be significant.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Histologically or cytologically confirmed previously treated metastatic colorectal cancer with adenocarcinoma histology and in Stage IV per American Joint Committee on Cancer (version 4.0) at study entry * Microsatellite status should be performed per local standard of practice, immunohistochemistry (IHC) and/or PCR. If IHC results are equivocal, PCR is required for determining microsatellite stable (MSS) status * Must have measurable disease per RECIST 1.1. Participants with lesions in a previously irradiated field as the sole site of measurable disease will be permitted to enroll provided the lesion(s) have demonstrated clear progression and can be measured accurately * Eastern Cooperative Oncology Group (ECOG) Performance Status of 0-1 at screening and on cycle 1 day 1 (C1D1) Exclusion Criteria: * BRAF V600 mutant colorectal cancer * Active brain metastases or leptomeningeal metastases * Active, known or suspected autoimmune disease * Participants with a condition requiring systemic treatment with either corticosteroids (\> 10 mg daily prednisone equivalents) or other immunosuppressive medications within 14 days of study treatment administration * History of interstitial lung disease or pneumonitis * Prior treatment with immune checkpoint inhibitors and mitogen-activated protein kinase enzymes (MEK) inhibitors * History of allergy or hypersensitivity to study drug components Other protocol defined inclusion/exclusion criteria apply
