Definition

A preparation of autologous T lymphocytes that have been transduced with a lentiviral vector to express a chimeric antigen receptor (CAR) consisting of a single chain variable fragment (scFv) of anti-CD19, coupled to the costimulatory domain of CD28, with potential immunostimulating and antineoplastic activities. Upon transfusion, the autologous anti-CD19 CAR-CD28 T cells ET019002 target, bind to, and induce selective toxicity in CD19-expressing B cells. The CD19 antigen is a B-cell-specific cell surface antigen expressed in all B-cell lineage malignancies.
