Talquetamab: First Approval.

Talquetamab (talquetamab-tgvs; TALVEY), a humanized, bispecific G-protein coupled receptor family C group 5 member D (GPRC5D)-directed CD3 T-cell engager, is being developed by Janssen for the treatment of multiple myeloma (MM). In early August 2023, talquetamab was granted accelerated approval in the USA for the treatment of adults with relapsed or refractory MM (RRMM) and in late August 2023, talquetamab was granted conditional marketing authorisation in the EU for the treatment of adult patients with RRMM. This article summarizes the milestones in the development of talquetamab leading to this first approval for RRMM.
