Summary

The purpose of this China extension study is to assess the safety and efficacy of coformulated favezelimab/pembrolizumab (MK-4280A) in adult Chinese participants with metastatic colorectal cancer. The study will also compare MK-4280A with the standard of care treatment of regorafenib and TAS-102 (trifluridine and tipiracil).
