Preferred Label : Anti-HER3/Topoisomerase I Inhibitor Antibody-drug Conjugate DB-1310;
NCIt synonyms : Anti-HER3 ADC DB-1310; Anti-HER3/Topoisomerase I Inhibitor ADC DB-1310;
NCIt definition : An antibody-drug conjugate (ADC) composed of a humanized immunoglobulin G1 (IgG1)
monoclonal antibody directed against human epidermal growth factor receptor 3 (HER3;
ErbB3) conjugated, via a maleimide tetrapeptide-based cleavable linker, to a cytotoxic
DNA topoisomerase I inhibitor, with potential antineoplastic activity. Upon administration
of anti-HER3 ADC DB-1310, the anti-HER3 antibody moiety targets and binds to HER3
expressed on tumor cells. Upon internalization, the topoisomerase I inhibitor targets
and binds to DNA topoisomerase I, thereby stabilizing the cleavable complex between
topoisomerase I and DNA and resulting in DNA breaks, inhibition of DNA replication
and apoptosis in HER3-expressing tumor cells. HER3, a member of the epidermal growth
factor receptor (EGFR) family of receptor tyrosine kinases, is frequently overexpressed
in tumors.;
