2seventy bio, Inc. is a cell and gene therapy company focused on the research, development, and commercialization of transformative treatments for cancer. The Company is focused on the commercialization and development of Abecma (idecabtagene vicleucel). Abecma is its B cell maturation antigen (BCMA)-targeted CAR T cell therapy for multiple myeloma, in collaboration with their partner Bristol Myers Squibb (BMS). ABECMA is a BCMA-directed genetically modified autologous T cell immunotherapy indicated 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 uses a lentiviral vector (LVV), to deliver a chimeric antigen receptor (CAR), with the potential to program a patient’s own T cells to recognize the plasma cell specific BCMA, protein on the cell surface.
