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.
