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.
Osimertinib is a kinase inhibitor that irreversibly binds to mutant EGFR forms (T790M, L858R, and exon 19 deletions) at approximately 9-fold lower concentrations than wild-type EGFR, inhibiting tumor cell proliferation in EGFR mutation-positive NSCLC; it also inhibits HER2, HER3, HER4, ACK1, and BLK at clinically relevant concentrations.
