anti-CD19-CD20-CAR-CD3zeta-4-1BB-expressing autologous T lymphocytes
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 in tandem with an anti-CD20 scFv, and coupled to the cytoplasmic portion of the zeta chain of the human T-cell receptor (CD3zeta), and the co-stimulatory molecule 4-1BB (CD137), with potential immunostimulating and antineoplastic activities. Upon transfusion, anti-CD19-CD20-CAR-CD3zeta-4-1BB-expressing autologous T lymphocytes recognize and direct T cells to CD19- or CD20-expressing tumor B cells. This results in a cytotoxic T-lymphocyte (CTL) response against CD19- or CD20-expressing tumor cells, and causes tumor cell lysis. Both CD19 and CD20 are B-cell-specific cell surface antigens overexpressed in B-cell lineage malignancies. Check for active clinical trials using this agent. (NCI Thesaurus)
