Overview
Brief Summary
The main purpose of this study is to compare the clinical benefit, as measured by Progression-Free Survival (PFS), Objective Response Rate (ORR), and Overall Survival (OS), achieved by nivolumab in combination with ipilimumab or by nivolumab monotherapy in participants with Microsatellite Instability High (MSI-H) or Mismatch Repair Deficient (dMMR) metastatic colorectal cancer (mCRC). This study will also compare nivolumab plus ipilimumab combination vs chemotherapy for treatment of MSI-H/dMMR mCRC participants.

Outcomes
Primary Outcomes
Progression-free Survival (PFS) by Blinded Independent Review Center (BICR) - Arm B vs. Arm A All Lines Centrally Confirmed MSI-H/dMMR
Time Frame: From date of randomization to the date of first objectively documented disease progression or death due to any cause, whichever occurs first (Up to approximately 60 months)
BICR-assessed Progression-free survival (PFS) is defined as the time from the randomization date to the date of first objectively documented disease progression per RECIST 1.1 (i.e, radiologic) or death due to any cause, whichever occurs first.
