Autologous CD19CAR-CD28-CD3zeta-EGFRt-expressing Tcm-enriched T CellsNCIt concept
Preferred Label : Autologous CD19CAR-CD28-CD3zeta-EGFRt-expressing Tcm-enriched T Cells;
NCIt synonyms : Autologous CD19R:CD28:lentiviral/EGFRt T Cells;
NCIt definition : A preparation of genetically modified autologous central memory (Tcm) enriched T-cells
transduced with a replication incompetent lentiviral vector expressing a chimeric
antigen receptor (CAR), containing a CD28 signaling domain fused to both CD3 zeta,
which targets the CD19 antigen, and a truncated form of the human epidermal growth
factor receptor (EGFRt), with potential immunostimulating and antineoplastic activities.
Upon intravenous administration, autologous CD19CAR-CD28-CD3zeta-EGFRt-expressing
Tcm-enriched T cells are directed to CD19-expressing tumor cells, thereby inducing
a selective toxicity in CD19-expressing tumor cells. CD19 antigen is a B-cell specific
cell surface antigen expressed in all B-cell lineage malignancies. Devoid of both
ligand binding domains and tyrosine kinase activity, EGFRt both facilitates in vivo
detection of the administered T-cells and can promote elimination of those cells upon
a cetuximab-induced antibody dependent cellular cytotoxicity response. The costimulatory
signaling domain enhances proliferation of T cells and antitumor activity.;
