Anti- DXD antibody, mAb

Anti-Dxd (Exatecan derivative for ADC) antibody, mAb

Background

Dxd (Exatecan derivative for ADC) is a potent DNA topoisomerase I inhibitor, with an IC50 of 0.31 μM, used as a

conjugated drug of HER2-targeting ADC (DS-8201a). Dxd is cytotoxic to human cancer cell lines of KPL-4,

NCI-N87, SK-BR-3, and MDA-MB-468 with IC50s of 1.43 nM-4.07 nM, but the control IgG-ADC (Dxd is the

payload) shows no inhibition on the four cell lines (with HER2 expression).

#YKMP18020 monoclonal antibody can recognize Dxd and Dxd structurally similar molecules.
