* Has a history of acute or chronic pancreatitis.
* Has neuromuscular disorders associated with an elevated creatine kinase (eg, inflammatory myopathies, muscular dystrophy, amyotrophic lateral sclerosis, spinal muscular atrophy).
* Has clinically significant cardiovascular disease within 12 months from first dose of study intervention, including New York Heart Association Class III or IV congestive heart failure, unstable angina, myocardial infarction, cerebral vascular accident, or cardiac arrhythmia associated with hemodynamic instability.

Summary
Brief summary
The purpose of this study is to assess the safety and efficacy of coformulated favezelimab/pembrolizumab (MK-4280A) in 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.
