Abstract:
4-1BB (CD137, TNFSF9) is a promising co-stimulatory signaling mediator of T cells and NK cells, and agonistic monoclonal antibodies targeting 4-1BB are under clinical investigations aiming to observe sufficient and prolonged anti-tumor efficacy. However, these trials have resulted in limited efficacy or safety, and different bispecific approaches are being explored to improve the profiles. BH3120, a bivalent bispecific antibody generated by Pentambody(TM) platform targeting 4-1BB and PD-L1 simultaneously, demonstrates strong and prolonged antitumor efficacy as monotherapy in in vivo studies, and favorable safety profiles up to 200mg/kg/dose in non-human primates. Moreover, combination of BH3120 with an immune checkpoint inhibitor shows synergistically enhanced anti-tumor efficacy. Supported by these results, IND enabling studies of BH3120 are on-going and clinical evaluations are planned from later in 2022.
