Definition

Genetically modified, autologous T lymphocytes transduced with a retroviral vector encoding a chimeric antigen receptor (CAR) specific for the tumor-associated antigen (TAA) Lewis-Y (LeY), with potential immunomodulating and antineoplastic activities. Upon intravenous administration, anti-LeY-CAR-transduced autologous T lymphocytes specifically target and induce selective toxicity in LeY-expressing tumor cells. LeY, a difucosylated carbohydrate antigen, is overexpressed by a variety of cancer cell types.
