Clinical Trial 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). The primary study hypothesis is that coformulated favezelimab/pembrolizumab (MK-4280A) is superior to standard of care with respect to overall survival.


Clinical Trial Description

The China extension study will include participants previously enrolled in China in the global study for MK-4280A-007 (NCT05064059) plus those enrolled during the China extension enrollment period. A total of approximately 94 Chinese participants will be enrolled. ;
