Randomized Controlled Trial Multicenter Study Comparative Study
Nivolumab plus Ipilimumab in Microsatellite-Instability-High Metastatic Colorectal Cancer.
Patients with microsatellite-instability-high (MSI-H) or mismatch-repair-deficient (dMMR) metastatic colorectal cancer have poor outcomes with standard chemotherapy with or without targeted therapies. Nivolumab plus ipilimumab has shown clinical benefit in nonrandomized studies of MSI-H or dMMR metastatic colorectal cancer. ⋯ Progression-free survival was longer with nivolumab plus ipilimumab than with chemotherapy among patients who had not previously received systemic treatment for MSI-H or dMMR metastatic colorectal cancer.
