Pharmacology
Durvalumab is a human IgG1 kappa monoclonal antibody that binds to PD-L1 and blocks the interaction of PD-L1 with PD-1 and CD80, releasing the inhibition of immune responses without inducing antibody-dependent cell-mediated cytotoxicity.
Amivantamab-vmjw is a bispecific antibody that binds EGFR and MET extracellular domains, disrupting ligand binding and receptor degradation, and targeting tumor cells for immune-mediated destruction via ADCC and trogocytosis.
