A Study of Nivolumab, Nivolumab Plus Ipilimumab, or Investigator's Choice Chemotherapy for the Treatment of Participants With Deficient Mismatch Repair (dMMR)/Microsatellite Instability High (MSI-H) Metastatic Colorectal Cancer (mCRC)

Sponsor: Bristol-Myers Squibb

Sponsor score: 60
Inactive

ClinicalTrials ID:NCT04008030

Patient View

This study evaluates nivolumab, alone or with ipilimumab, versus chemotherapy in MSI-H/dMMR mCRC. Eligible participants have recurrent/metastatic CRC, MSI-H/dMMR status, and ECOG ≤1. Exclusions include autoimmune diseases and HIV/AIDS. Interventions include ipilimumab, oxaliplatin, leucovorin, fluorouracil, irinotecan, bevacizumab, cetuximab, and nivolumab.

Patient Parameters

Program Overview

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.
