The Republic of Ireland's Health Service Executive (HSE) has approved nivolumab in combination with ipilimumab for reimbursement as a treatment option for the treatment of adult patients with mismatch repair deficient or microsatellite instability-high metastatic colorectal cancer (MSI-H mCRC) after prior fluoropyrimidine-based combination chemotherapy.

This statement is based on a regulatory approval from the Health Service Executive:
