MacroGenics presented preliminary non-clinical data from a DART program designed to engage both HER2 and CD137 (4-1BB), a costimulatory molecule, allowing for tumor-targeted immune cell activation. In these two bispecific antibodies, one of the two chains making the DART is fused to homodimeric Fc, thus resulting in a tetravalent bispecific molecule. For example, MacroGenics is developing two bispecific antibodies to block checkpoint inhibitors, MGD013 and MGD019 (Table 2), where multivalency for each antigen could be advantageous. Despite the success of monoclonal antibodies (mAbs) to treat some disorders, the monospecific molecular entity of mAbs as well as the presence of multiple factors and pathways involved in the pathogenesis of disorders, such as various malignancies, infectious diseases, and autoimmune disorders, and resistance to therapy have restricted the therapeutic efficacy of mAbs in clinical use.
