Trastuzumab deruxtecan (solution)  (Synonyms: DS-8201 (solution); DS-8201a (solution))

Trastuzumab deruxtecan (T-DXd; DS-8201a) (solution) is an anti-human epidermal growth factor receptor 2 (HER2) antibody-drug conjugate (ADC). Trastuzumab deruxtecan is composed of a humanized anti-HER2 antibody, an enzymatically cleavable peptide-linker, a topoisomerase I inhibitor (a toxin component of Dxd). Trastuzumab deruxtecan can be used for the research of HER2-positive breast cancer and gastric cancer^[1][2].

Trastuzumab deruxtecan (1 pM-10 nM; 5 days) (solution) inhibits the growth of HER2-positive KPL-4 cells, with an IC₅₀ of 109.7 pM^[2].
Trastuzumab deruxtecan (10 nM; 5 days) (solution) shows bystander killing effects in HER2-negative MDA-MB-468 cells^[2].

Trastuzumab deruxtecan (3 mg/kg; a single i.v.) (solution) shows antitumor activity against not only HER2-positive tumors but also HER2-negative tumors under the co-inoculated condition^[2].
Trastuzumab deruxtecan (10 mg/kg; i.v. on days 0 and 7) (solution) inhibits the tumor growth in in EMT6-hHER2 syngeneic mouse model^[3].
