Background

Teclistamab is an IgG4-PAA bispecific antibody that targets the CD3 receptor expressed on the surface of T cells and B cell maturation antigen (BCMA) expressed on malignant multiple myeloma cells. Teclistamab consists of an anti-BCMA arm and an anti-CD3 arm connected via two interchain disulfide bonds, allowing the drug to recruit CD3-expressing T cells to BCMA-expressing cells to promote T cell–mediated cytotoxicity.

On August 24, 2022, the European Commission (EC) granted conditional marketing authorization of teclistamab as first-in-class bispecific antibody for the treatment of multiple myeloma, marking its first global approval. Teclistamab was later granted accelerated approval by the FDA on October 25, 2022.

Indication

Teclistamab is indicated as monotherapy for the treatment of adult patients with relapsed and refractory multiple myeloma who have received at least three prior therapies, including an immunomodulatory agent, a proteasome inhibitor, and an anti-CD38 antibody and have demonstrated disease progression on the last therapy.

Teclistamab is approved by the EC and FDA under conditional marketing authorization and accelerated approval, respectively. New evidence for this drug will be continuously monitored and reviewed, which will affect continued approval for the drug's indication.
