Bispecific antibodies (BsAbs) represent a breakthrough in therapeutic antibody engineering. Unlike traditional monoclonal antibodies, BsAbs can simultaneously bind to two different antigens or two distinct epitopes on the same antigen—unlocking unique mechanisms of action that single antibodies cannot achieve. This innovation has made BsAbs one of the most promising strategies in cancer immunotherapy and beyond, with multiple FDA- and EMA-approved drugs already transforming patient care worldwide.
