Abecma Review Delayed for Panel Input
FDA has delayed a 12/16-expected review decision on a Bristol Myers Squibb and 2seventy bio supplemental BLA for Abecma (idecabtagene vicleucel) and its use in earlier lines of triple-class exposed relapsed or refractory multiple myeloma (RRMM). The agency has elected to seek input from its Oncologic Drugs Advisory Committee on the submission’s data from the pivotal Phase 3 KarMMa-3 study before rendering a review decision, according to the companies.
They expect panel members to review data related to the secondary endpoint of overall survival. They note that convening the meeting will have no impact on the currently approved indication for Abecma for adult patients with triple-class exposed RRMM after four or more prior lines of therapy.
“The KarMMa-3 study met its primary endpoint, demonstrating a statistically significant improvement in progression-free survival (PFS) compared to standard regimens, significantly reducing the risk of disease progression or death versus standard regimens in patients with triple-class exposed RRMM,” the companies say. “Safety results were consistent with the well-established and generally predictable safety profile of Abecma.”
Abecma is described as a B-cell maturation antigen-directed genetically modified autologous chimeric antigen receptor T-cell therapy. Each dose of Abecma is a customized treatment created by using a patient’s own T-cells, which are “genetically modified to include a new gene that facilitates targeting and killing myeloma cells. Once the cells are modified, they are infused back into the patient.
