This clinical trial is focused on studying treatments for colon cancer, specifically in cases where the cancer has returned or spread to other parts of the body. The study is investigating the effectiveness of a medication called Nivolumab, which may be used alone or in combination with other medications. These combinations include Nivolumab with Ipilimumab, Nivolumab with an anti-LAG3 agent known as Relatlimab, and Nivolumab with Daratumumab. The purpose of the study is to see if these treatments can produce a significant response in patients with a specific marker in their tumors.
The study involves patients with two types of colorectal cancer: those with MSI Positive Colorectal Cancer and those with MSI Negative Colorectal Cancer. MSI stands for microsatellite instability, which is a condition of genetic hypermutability that results from impaired DNA mismatch repair. The trial aims to determine the objective response rate, which is a measure of how well the cancer responds to the treatment, in both types of patients.
Participants in the study will receive the treatments through intravenous infusion, which means the medication is delivered directly into the bloodstream through a vein. The study will monitor the response of the cancer to these treatments over time. The trial is designed to provide valuable information on the potential benefits of these treatment combinations for patients with recurrent and metastatic colon cancer.
