Current use of CAR T cells to treat multiple myeloma

Abstract Anti–B-cell maturation antigen (BCMA) chimeric antigen receptor (CAR) T-cell therapies currently approved by the US Food and Drug Administration (FDA) have dramatically improved clinical outcomes for patients with heavily pretreated multiple myeloma who have disease refractory to conventional proteasome inhibitors, immunomodulatory drugs, and anti-CD38 monoclonal antibodies. However, despite this progress, multiple myeloma remains an incurable hematologic malignancy. In this review, we discuss practical considerations for currently FDA approved CAR T-cell therapies, including newer data evaluating those agents in earlier lines of therapy. We also discuss considerations for patients following relapse from anti-BCMA CAR T-cell therapy, which currently represents an unmet clinical need.
