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.
Dabrafenib is a BRAF kinase inhibitor that targets mutated BRAF V600E, V600K, and V600D enzymes, inhibiting cell growth in BRAF V600 mutation-positive tumors.
