NCT ID NCT07409844

First seen Feb 15, 2026 · Last updated May 16, 2026 · Updated 7 times

Summary

This study tests whether giving the immunotherapy drug pembrolizumab before planned surgery can shrink or eliminate tumors in people with a specific type of colon cancer (dMMR). About 152 participants with stage I to III colon cancer will receive different doses of the drug. If scans and exams show no cancer left, they may avoid surgery and instead be closely monitored. If cancer remains, standard surgery and possibly chemotherapy will follow.
