Evaluating a Surgical-Sparing Approach Using Cemiplimab With or Without Fianlimab to Treat Older Patients With Localized or Locally Advanced MSI-H Colorectal Cancer
The purpose of this study is to evaluate the safety and clinical activity of cemiplimab and the combination of cemiplimab/fianlimab in microsatellite unstable localized or locally advanced colorectal cancer diagnosed in patients age 70 or greater or in patients age 18 or greater considered poor candidates for surgery or unwilling to undergo surgery.
