Pharmacology
Panitumumab is a fully human IgG2 monoclonal antibody that competitively blocks ligand binding to EGFR, inhibiting receptor autophosphorylation and downstream signaling, thereby inhibiting tumor cell growth and inducing apoptosis; in KRAS G12C-mutated mCRC, combining EGFR blockade with sotorasib overcomes EGFR-mediated resistance to KRAS G12C inhibition.
Pembrolizumab is a PD-1 blocking antibody that releases PD-1 pathway-mediated inhibition of the immune response by preventing the interaction of PD-1 with its ligands PD-L1 and PD-L2, thereby restoring anti-tumor immune response.
