Purpose of review: The introduction of bispecific antibodies is one of the most significant recent advances in the treatment of relapsed/refractory multiple myeloma. This review will summarize the management of the toxicities associated with newly approved T cell-engaging bispecific antibodies and those which may be approved in the near future.
Recent findings: Numerous trials have shown that bispecific antibodies can be both effective and tolerable when adverse events are properly managed. Cytokine release syndrome and increased infections are observed across all bispecific antibodies. Additional adverse events are target-specific, such as the more severe hypogammaglobulinemia and infections of BCMA bispecific antibodies and the dysgeusia, nail dystrophy, and skin changes of GPRC5D bispecific antibodies. Bispecific antibodies will surely become a mainstay of multiple myeloma therapy given their efficacy and accessibility. Their unique toxicities must be carefully considered and managed to ensure they are utilized safely.
