Bristol Myers Squibb and bluebird bio, Inc. today announced that the U.S. Food and Drug Administration (FDA) has approved Abecma (idecabtagene vicleucel; ide-cel) as the first B-cell maturation antigen (BCMA)-directed chimeric antigen receptor (CAR) T cell immunotherapy for the treatment of adult patients with relapsed or refractory multiple myeloma after four or more prior lines of therapy, including an immunomodulatory agent, a proteasome inhibitor, and an anti-CD38 monoclonal antibody.
Abecma is a personalized immune cell therapy approved as a one-time infusion with a recommended dose range of 300 to 460 x 10^6 CAR-positive T cells. As an anti-BCMA CAR T cell therapy, Abecma recognizes and binds to BCMA, a protein that is nearly universally expressed on cancer cells in multiple myeloma, leading to the death of BCMA-expressing cells.
Yesterday was the PDUFA date.
FDA approval of ide-cel by 3/31/21 was one of the three requirements for the $9/sh Celgene CVR to pay off, but this became moot when a distinct CAR-T, liso-cel was not approved by its 12/31/20 deadline (#msg-160628371). The FDA approved liso-cel for DLBCL with the brand name, Breyanzi on 2/5/21 (#msg-161552697).
