Description
PD-1 inhibitors are used in the treatment of metastatic colorectal cancer (mCRC) for patients with mismatch repair deficient tumors; they have shown efficacy as a second-line or later therapy, particularly when combined with other immunotherapies or chemotherapy.
Mechanism of Action
PD-1 inhibitors block the interaction between PD-1 and its ligands, thereby enhancing T-cell activation and proliferation; this mechanism is crucial for restoring anti-tumor immunity.
