Overview
Elranatamab is a bispecific B-cell maturation antigen (BCMA)-directed CD3 T-cell engager. It is a humanized immunoglobulin 2-alanine kappa antibody derived from two monoclonal antibodies (mAbs), an anti-BCMA mAb and an anti-CD3 mAb, each of which contributes one heavy chain and one light chain to drug structure. The resulting 4-chain bispecific antibody is covalently linked via five inter-chain disulfide bonds. On August 14, 2023, the FDA granted accelerated approval to elranatamab for the treatment of multiple myeloma.
Background
Elranatamab is a bispecific B-cell maturation antigen (BCMA)-directed CD3 T-cell engager. It is a humanized immunoglobulin 2-alanine kappa antibody derived from two monoclonal antibodies (mAbs), an anti-BCMA mAb and an anti-CD3 mAb, each of which contributes one heavy chain and one light chain to drug structure. The resulting 4-chain bispecific antibody is covalently linked via five inter-chain disulfide bonds. On August 14, 2023, the FDA granted accelerated approval to elranatamab for the treatment of multiple myeloma.
Indication
Elranatamab is indicated for the treatment of adult patients with relapsed or refractory multiple myeloma who have received at least four prior lines of therapy, including a proteasome inhibitor, an immunomodulatory agent, and an anti-CD38 monoclonal antibody. This indication is approved under accelerated approval based on response rate and durability of response. Continued approval for this indication may be contingent upon verification of clinical benefit in a confirmatory trial(s).
