Anti-CD137 and PD-1/PD-L1 Antibodies En Route toward Clinical Synergy

T-cell costimulation and coinhibition can be respectively exploited by blocking and agonist mAbs. Both strategies can be synergistically combined in mouse models. Early clinical results from combinations of anti–PD-1 mAbs in conjunction with agonist anti-CD137 (4-1BB) mAbs show excellent safety and promising efficacy.
