General information
Class/mechanism from the NCI Drug Dictionary: A bispecific monoclonal antibody against human CD3, a T-cell surface antigen, and human B-cell maturation antigen (BCMA; TNFRSF17), a tumor-associated antigen (TAA) expressed on plasma cells, with potential antineoplastic activity. Upon administration, elranatamab binds to both CD3 on T cells and BCMA expressed on malignant plasma cells. This results in the cross-linking of T cells and tumor cells, and induces a potent cytotoxic T-lymphocyte (CTL) response against BCMA-expressing plasma cells.
