Ifinatamab deruxtecan
Based on 1 Customer Validation
Ifinatamab deruxtecan (DS-7300a) is a B7-H3-targeting Antibody-drug conjugate (ADC), which is composed of a humanized anti-B7-H3 monoclonal antibody, an enzymatically cleavable peptide-based linker, and Exatecan derivative (DXd) (HY-13631D). Ifinatamab deruxtecan is a DNA Topoisomerase I inhibitor. Ifinatamab deruxtecan induces Apoptosis. DS-7300a exerts potent antitumor activities against B7-H3-expressing tumors. against rhabdomyosarcoma, endometrial adenocarcinoma and lung adenocarcinoma. Ifinatamab deruxtecan does not exert direct immunomodulatory effects

Ifinatamab deruxtecan inhibits the growth of B7-H3-expressing cancer cells in vitro, but not of B7-H3-negative cancer cells[1].
Ifinatamab deruxtecan (6 days) potently and selectively inhibits the growth of B7-H3-expressing RH-41 and MFE-280 cancer cells in vitro, with no activity against B7-H3-negative CCRF-CEM cells[2].
Ifinatamab deruxtecan (10 μg/mL; 72 hours) induces DNA damage and apoptosis in B7-H3-expressing RH-41 cancer cells in vitro[2].

Cell Line:Human rhabdomyosarcoma (RH-41) cells
-
Concentration:10 μg/mL
-

Result:Induced phosphorylation of Chk1 (a DNA damage marker) in RH-41 cells. Induced cleavage of PARP (an apoptosis marker) in RH-41 cells.
Ifinatamab deruxtecan (0.3-3 mg/kg; i.v.; days 0 and 14) exerts potent antitumor activity against endometrial adenocarcinoma xenografts in mice, achieving 67% TGI at 0.3 mg/kg and complete tumor growth inhibition (100% TGI) at 1 mg/kg and 3 mg/kg[2].
Ifinatamab deruxtecan (1-10 mg/kg; i.v.; days 0 and 14) exerts potent dose-dependent antitumor activity against lung adenocarcinoma xenografts in mice[2].
