NCIt synonyms : Autologous Anti-CD19 Antibody Redirected T Cells with Endogenous Modular Immune Signaling
EB103; Autologous Anti-CD19 AbTCR-expressing T-cells EB103; Autologous CD19-redirected ARTEMIS T Cells EB103;
NCIt definition : A preparation of autologous T-lymphocytes transduced with a lentiviral vector encoding
an antibody-T-cell-receptor (AbTCR) composed of a CD19-binding domain derived from
an antibody fragment antigen binding (Fab) region and an effector domain derived from
human gamma/delta TCR, and a co-stimulatory molecule composed of a CD19-binding domain
derived from a single-chain variable fragment (scFv) and a co-stimulatory domain derived
from a human co-stimulatory receptor, with potential immunostimulating and antineoplastic
activities. Upon administration of the autologous anti-CD19 AbTCR-expressing T-lymphocytes
EB103, both the AbTCR moiety and the co-stimulatory molecule recognize and bind to
CD-19-expressing tumor cells, resulting in specific T-cell-mediated tumor cell lysis.
CD19, a B-cell-specific cell surface antigen, is overexpressed in B-cell lineage malignancies.;
