ICIs (** Keytruda (pembrolizumab), Opdivo (nivolumab), Yervoy (ipilimumab), Tecentriq (atezolizumab) **)
Other Medications
Description
ICIs are used for the treatment of microsatellite instability-high (MSI-H) or mismatch repair deficient (dMMR) metastatic colorectal cancer after progression on fluoropyrimidine, oxaliplatin and irinotecan; they have shown efficacy in patients with MSI-H/dMMR tumors but not typically in those with microsatellite stable (MSS) CRC.
Mechanism of Action
ICIs, such as pembrolizumab and nivolumab, block the PD-1 receptor on T-cells, enhancing their ability to recognize and attack cancer cells; ipilimumab targets CTLA-4, another immune checkpoint, thereby activating a broader T-cell response.
