Abstract
Multiple myeloma (MM) remains an incurable malignancy originating from plasma cells. Despite significant advances in treatment, relapses remain inevitable, and novel therapies continue to be needed. Teclistamab-cqyv is a first-in-class, bispecific T-cell engager (BiTE) antibody for the treatment of MM. Teclistamab-cqyv activates the immune system by binding to the cluster of differentiation 3 (CD3) receptor expressed on the surface of T cells and to the B-cell maturation antigen (BCMA) expressed on the surface of MM cells and some healthy B-lineage cells. Teclistamab-cqyv has been shown to be effective in a pivotal trial that demonstrated an overall response rate of more than 60% in heavily pretreated patients. Compared with other BCMA-targeted agents, the side effect profile of teclistamab-cqyv suggests a more tolerable option for elderly patients. Teclistamab-cqyv is now approved by the US Food and Drug Administration (FDA) as monotherapy for the treatment of adult patients with relapsed or refractory MM.
