FDA Approves Janssen’s Talvey

Share

FDA has granted accelerated approval to Janssen’s Talvey (talquetamab-tgvs), described as a first-in-class bispecific therapy to treat 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 antibody. The company says the accelerated approval was based on response rate and durability of response and continued approval for the indication is contingent upon verification and description of clinical benefit in confirmatory trials.

Talvey is a bispecific T-cell engaging antibody that binds to the CD3 receptor on the surface of T cells and G protein-coupled receptor class C group 5 members expressed on the surface of multiple myeloma cells, non-malignant plasma cells, and healthy tissue such as epithelial cells in keratinized tissues of the skin and tongue, Janssen says. It is approved as a weekly or biweekly subcutaneous injection after an initial step-up phase.

FDA has granted Talvey orphan drug designation to treat multiple myeloma and breakthrough therapy designation to treat adult patients with relapsed or refractory multiple myeloma who have previously received at least four specific lines of therapy. FDA gave the Talvey BLA a priority review.
