NCT ID NCT05194995
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a new drug (JAB-21822) combined with cetuximab in people with advanced colorectal, small intestine, or appendiceal cancers that have a specific KRAS G12C mutation. Participants must have already tried at least one standard treatment. The goal is to see if the combination is safe and can shrink tumors. This is not a cure, but aims to control the disease.
