[Research Progress of Bispecific Antibodies in Treatment of Multiple Myeloma--Review].

ABSTRACT

Multiple myeloma (MM) is an incurable malignant plasma cell diseases, the incidence of which is increasing year by year. The application of immunomodulators drugs, proteasome inhibitors, anti-CD38 antibodies, CAR-T, and HSCT have significantly improved the prognosis of patients with MM, however new therapeutic tools need to be developed to improve the prognosis of patients with relapsed/refractory after conventional regimens treatment. Bispecific antibodies are a novel immunotherapeutic approach that generates immune synapses by binding to targets on malignant plasma cells and cytotoxic immune effector cells (T cells/natural killer cells), leading to T/NK cells activation and malignant plasma cell lysis. Several preclinical and phase I clinical studies have shown good efficacy, bringing new possibilities for patients with relapsed/refractory MM to improve their prognosis in the future in combination with the rest of the treatment options. This article summarizes the classification of bispecific antibodies developed in recent years, and the results of preclinical and clinical trials, which will provide some reference for treating MM.
