NCIt definition : A preparation of autologous human T-lymphocytes transduced with a CARv3-TEAM-E lentiviral
vector encoding for an anti-epidermal growth factor receptor (EGFR) variant III (EGFRvIII)
mutant chimeric T cell receptor (chimeric antigen receptor or CAR) and a T cell engaging
antibody molecule (TEAM) which comprises a bispecific T-cell engager (BiTE) against
EGFR and the T-cell signaling domain CD3, with potential immunostimulatory and antineoplastic
activities. Upon administration via Ommaya reservoir of the anti-EGFRvIII CAR-CD3/EGFR
BiTE-transduced autologous T-lymphocytes CARv3-TEAM-E, the lymphocytes bind to the
EGFRvIII antigen on tumor cell surfaces and the BiTE binds to CD3 on bystander T-cells;
thereby killing EGFRvIII-expressing tumor cells through the administered CAR-T cells
and wild-type (WT) EGFR-expressing tumor cells by bystander T-cells, respectively.
EGFRvIII, an in-frame deletion of exons 2-7 in the EGFR gene, is overexpressed by
a variety of cancer cell types and absent in normal, healthy cells; it plays a key
role in tumor cell proliferation, tumor angiogenesis and radio- and chemoresistance.;
