The promise of bispecific antibodies: Clinical applications and challenges

The development of cancer therapies using monoclonal antibodies has been successful during the last 30 years. Recently much progress was achieved with technologies involving bispecific and multi-specific antibodies. Bispecific antibodies (BsAbs) are antibodies that bind two distinct epitopes, and a large number of potential clinical applications of BsAbs have been described. Here we review mechanism of action, clinical development and future challenges of BsAbs which could be a serve as a valuable arsenal in cancer patients.
