HER3 and MUC1 are co-expressed in a variety of solid tumors, especially those with the highest mortality.

DM002 is a novel fully human bispecific antibody-drug conjugate generated by the RenLite® common light chain mouse platform. DM002 cross-reacts with human and monkey HER3 and the MUC1 juxtamembrane domain.

DM002 displayed higher endocytosis activity and more potent tumor growth inhibition of HER3 and MUC1 co-expressing tumors (especially HER3low tumors) compared to HER3 and MUC-1 benchmarks.

DM002 is a promising First-In-Class ADC with potential to treat a variety of HER3 and MUC-1-expressing cancers.
