NCIt synonyms : Autologous Anti-CD20/CD19-targeting Tandem CAR T Cells MB-CART2019.1; Autologous pLTG1497-transduced CAR T-cells MB-CART2019.1;
NCIt definition : A preparation of autologous CD4/CD8 enriched T-lymphocytes engineered to express pLTG1497,
a tandem chimeric antigen receptor (CAR) specific for the two tumor-associated antigens
(TAAs) cluster of differentiation 19 (CD19) and CD20, with potential immunostimulating
and antineoplastic activities. Upon administration, zamtocabtagene autoleucel target
and bind to CD19- and CD20-expressing tumor B-cells. This induces selective toxicity
in tumor B-cells expressing these TAAs. Both CD19 and CD20 are B-cell-specific cell
surface antigens overexpressed in B-cell lineage malignancies. Targeting both CD19
and CD20 may prevent tumor cell antigen escape and relapse.;
