datopotamab deruxtecan - Medications

Datopotamab deruxtecan-dlnk is a Trop-2-directed antibody and topoisomerase inhibitor conjugate. Datopotamab deruxtecan-dlnk is an antibody-drug conjugate (ADC) composed of three components: 1) a humanized anti-Trop-2 IgG1 monoclonal antibody (mAb), covalently linked to 2) a topoisomerase I inhibitor, via 3) a tetrapeptide-based cleavable linker. Deruxtecan is composed of a protease-cleavable maleimide tetrapeptide linker and the topoisomerase inhibitor, DXd, which is an exatecan derivative. The antibody is produced in Chinese hamster ovary cells by recombinant DNA technology, and the topoisomerase inhibitor and linker are produced by chemical synthesis. Approximately 4 molecules of deruxtecan are attached to each antibody molecule. Datopotamab deruxtecan-dlnk has the following structure: DATROWAY (datopotamab deruxtecan-dlnk) for injection is a sterile, white to yellowish white, preservative-free lyophilized powder in single-dose vials. Each vial delivers 100 mg of datopotamab deruxtecan-dlnk, L-histidine (3.88 mg), L-histidine hydrochloride monohydrate (5.25 mg), polysorbate 80 (1.50 mg), and sucrose (450 mg). Following reconstitution with 5 mL of Sterile Water for Injection, USP, the resulting concentration of datopotamab deruxtecan-dlnk is 20 mg/mL with a pH of 6.0. The resulting solution is administered by intravenous infusion following dilution. Chemical Structure
