Share

FDA has approved Janssen Biotech’s Tecvayli (teclistamab) in combination with Darzalex Faspro (daratumumab hyaluronidase-fihj) for adult patients with relapsed or refractory multiple myeloma who have received at least one prior line of therapy including a proteasome inhibitor and an immunomodulatory agent. The approval also converts teclistamab’s previous accelerated approval to traditional approval, as monotherapy, in adults 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. Teclistamab received accelerated approval for this indication in 2022. 

The action is part of the FDA Commissioner’s National Priority Review Voucher pilot program, which is designed to accelerate the review of products with the potential to address key national priorities, according to an agency release.

FDA based its decision on says from MajesTEC-3 (NCT05083169), a randomized, open-label, multi-center trial. The major efficacy outcome measure was progression-free survival (PFS) by independent review committee assessment based on International Myeloma Working Group 2016 criteria. Overall survival (OS) was an additional efficacy outcome measure.

The prescribing information for Tecvayli includes a Boxed Warning for life threatening or fatal cytokine release syndrome (CRS) and neurologic toxicity, including immune effector cell-associated neurotoxicity (ICANS). Tecvayli is available only through a restricted program under a Risk Evaluation and Mitigation Strategy (REMS), called the Tecvayli-Talvey REMS.

In addition to CRS, the most common side effects of Tecvayli in combination with daratumumab hyaluronidase-fihj include hypogammaglobulinemia, upper respiratory tract infection, cough, diarrhea, musculoskeletal pain, Covid-19, pneumonia, injection site reaction, fatigue, pyrexia, headache, nausea, gastroenteritis, and decreased weight, FDA says.
