First seen May 02, 2026 · Last updated May 13, 2026 · Updated 1 time

Summary

This study tests whether a short course of radiation combined with immunotherapy (iparomlimab and tuvonralimab), a targeted drug (regorafenib), and chemotherapy (CAPOX) can shrink advanced rectal cancer before surgery. About 88 adults with a specific type of rectal cancer will be randomly assigned to one of two treatment schedules. The goal is to see if this approach leads to a complete response, meaning no cancer remains after treatment.
