Definition

A preparation of autologous T lymphocytes that have been genetically modified to express a chimeric antigen receptor (CAR) targeting the tumor-associated antigen (TAA) CD20 (cluster of differentiation 20), and CD4/CD8 enriched, with potential immunostimulating and antineoplastic activities. Upon administration, MB-CART20.1 specifically recognize and kill CD20-expressing tumor cells. The CD20 antigen, a non-glycosylated cell surface phosphoprotein, is a B-cell specific cell surface antigen expressed in B-cell lineage malignancies and certain melanoma cell subpopulations.
