NCT ID NCT03657641
First seen Jun 19, 2026 · Last updated Jun 19, 2026
Summary
This study combines two drugs—regorafenib (a chemotherapy pill) and pembrolizumab (an immunotherapy)—to treat metastatic colorectal cancer that has spread and not responded to earlier treatments. The trial has two phases: first to find the safest dose, then to see if the combo helps people live longer without their cancer growing. It involves 73 adults who have already tried standard chemotherapies.
