2025-04-30 Van Allen lab The FDA provided regular approval to nivolumab in combination with ipilimumab the treatment of adults and pediatric patients 12 years and older with microsatellite instability-high (MSI-H) or DNA mismatch repair deficient (dMMR), metastatic colorectal cancer that has progressed following treatment with a fluoropyrimidine, oxaliplatin, and irinotecan. However, they split the approval in two indications: as a single agent and still as a combination for patients who have progressed on the previously listed therapies. We added a new indication to cover the combination treatment and updated all statements and propositions accordingly.
