Study on the Effectiveness and Safety of the Combination of the Two Drugs Regorafenib and Nivolumab in Patients With Colorectal Cancer (Cancer of the Colon or Rectum Classified as Proficient Mismatch Repair and Microsatellite Stable)

Status: Active

Description

The purpose of this study is to learn if combination of the two drugs regorafenib and nivolumab is an effective treatment for pMMR - MSS colorectal cancer, a special type of cancer of the colon or rectum (pMMR stands for proficient Mismatch Repair; MSS stands for Microsatellite Stable) and whether it is safe for patients. Regorafenib works by blocking several different proteins involved in tumor growth. Nivolumab is an immunotherapy drug encouraging the body's own immune system to attack cancer cells. Both drugs have been approved, but not for how they are being used as combination therapy in this study. Brand name of regorafenib is Stivarga; brand name of nivolumab is Opdivo.
