Pharmacology
Ramucirumab is a VEGFR2 antagonist that specifically binds VEGFR2 and blocks binding of VEGFR ligands VEGF-A, VEGF-C, and VEGF-D, inhibiting ligand-stimulated activation of VEGFR2 and thereby inhibiting endothelial cell proliferation, migration, and angiogenesis.
Fam-trastuzumab deruxtecan-nxki is a HER2-directed antibody-drug conjugate consisting of a humanized anti-HER2 IgG1 antibody linked to a topoisomerase I inhibitor (DXd). After binding to HER2 on tumor cells, the drug undergoes internalization and lysosomal cleavage, releasing the membrane-permeable DXd that causes DNA damage and apoptotic cell death.
