Description
PDR001 is a monoclonal antibody that functions as a PD-1 (programmed death-1) checkpoint inhibitor immunotherapy agent. In colorectal cancer treatment, it works by blocking the PD-1 receptor on T-cells, preventing cancer cells from evading immune system detection. Based on clinical trial data, it has been tested in combination with various targeted agents including MEK inhibitors, mTOR inhibitors, and Wnt pathway modulators for enhanced therapeutic efficacy in CRC patients.
Mechanism of Action
PDR001 binds specifically to the PD-1 receptor expressed on activated T-lymphocytes, blocking the interaction between PD-1 and its ligands PD-L1 and PD-L2. This blockade prevents the inhibitory signals that normally suppress T-cell activation, thereby restoring the immune system's ability to recognize and attack colorectal cancer cells.
