NCIt definition : A preparation of ex vivo expanded autologous CD8 and CD4 T-cells that have been
genetically modified to express a chimeric antigen receptor (CAR) specific for human
B-cell maturation antigen (BCMA; tumor necrosis factor receptor superfamily member
17; TNFRSF17), with potential immunostimulating and antineoplastic activities. Upon
administration, autologous anti-BCMA-CAR-expressing CD4 /CD8 T-lymphocytes FCARH143
specifically recognize and induce selective toxicity in BCMA-expressing tumor cells.
BCMA, a tumor specific antigen and a receptor for both a proliferation-inducing ligand
(APRIL) and B-cell activating factor (BAFF), is a member of the tumor necrosis factor
(TNF) receptor superfamily (TNFRSF) and plays a key role in plasma cell survival.
BCMA is found on the surfaces of plasma cells and overexpressed on malignant plasma
cells.;
