Pharmacology
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.
Bevacizumab-bvzr binds VEGF and prevents its interaction with receptors Flt-1 and KDR on the surface of endothelial cells, inhibiting endothelial cell proliferation, new blood vessel formation, and metastatic disease progression.
