Talvey

Generic name: Talquetamab-tgvs
Dosage form: injection, for subcutaneous use
Drug class: Miscellaneous antineoplastics

Usage of Talvey

Talvey (talquetamab-tgvs) is used to treat adults with multiple myeloma, a cancer of the bone marrow. Talvey is a T-cell engager that works by attaching to myeloma cancer cells and the immune system (T cells), which activates the immune system to kill multiple myeloma cells. Talvey is a bispecific GPRC5D-directed CD3 T-cell engager, which means that it targets GPRC5D on myeloma cells and CD3 on the surface of T cells. 

Talvey is used when cancer has not responded to treatment (refractory) or has come back after treatment (relapsed). Talvey is FDA-approved to be used by patients who have already received at least 4 different treatment regimens, including a proteasome inhibitor, an immunomodulatory agent, and an anti-CD38 monoclonal antibody to treat their multiple myeloma, AND their cancer has come back or did not respond to prior treatments.

Talvey received FDA approval on August 9, 2023, for the Janssen Pharmaceutical Companies of Johnson & Johnson.
