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.
Lorlatinib is a kinase inhibitor with activity against ALK and ROS1, as well as multiple mutant forms of ALK including resistance mutations detected at progression on prior ALK inhibitors; antitumor activity is dose-dependent and correlates with inhibition of ALK phosphorylation.
