Brief summary
The purpose of this study is to evaluate the safety and clinical activity of nivolumab and relatlimab in patients with metastatic or locally advanced microsatellite stable (MSS) colorectal cancer.
Interventions
Nivolumab was administered IV on day 1 of each 28 day cycle.
Relatlimab was administered IV on day 1 of each 28 day cycle.

Outcome results
Objective Response Rate (ORR)
ORR is defined as the number of patients achieving a complete response (CR) or partial response (PR) based on RECIST 1.1 criteria. CR = disappearance of all target lesions, PR is =\>30% decrease in sum of diameters of target lesions. Participants who discontinue due to toxicity or clinical progression prior to post-baseline tumor assessments will be considered as non-responders. Participants who discontinue for other reasons prior to their first dose of study drug will not included in the analysis.
