Datopotamab deruxtecan (DS-1062) is an antibody-drug conjugate (ADC) that targets tropomyosin 2 (TROP2) on the surface of trophoblast cells. Datopotamab deruxtecan exhibits antitumor activity by specifically binding to TROP2 and internalizing, releasing DXd to inhibit topoisomerase I (IC50 = 0.31 µM), thereby inducing DNA damage and apoptosis. Datopotamab deruxtecan induces significant antibody-dependent cellular cytotoxicity in the presence of peripheral blood lymphocytes and inhibits tumor growth in xenograft models.
