Preferred Label : Autologous Anti-BCMA CAR T-cells IM21;
NCIt synonyms : IM21 CAR T-cells; Autologous BCMA-specific CAR T-cells IM21;
NCIt definition : A preparation of autologous T-lymphocytes that have been transduced with a lentiviral
vector (LV) expressing a chimeric antigen receptor (CAR) targeting the human tumor-associated
antigen (TAA) B-cell maturation antigen (BCMA; tumor necrosis factor receptor superfamily
member 17; TNFRSF17) and containing, as of yet undisclosed costimulatory signaling
domains, with potential antineoplastic activity. Upon administration, the autologous
anti-BCMA CAR T-cells IM21 recognize and induce selective toxicity against 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 receptor superfamily (TNFRSF) and plays a key role in plasma cell survival.
BCMA is found on the surfaces of plasma cells and is overexpressed on malignant plasma
cells.;
