NCIt definition : Autologous human T-lymphocytes transduced with a retroviral vector encoding a T-cell
receptor (TCR) specific for the human melanoma antigen A4 (MAGE-A4) and the CD8alpha
co-receptor, with potential immunostimulatory and antineoplastic activities. Upon
leukapheresis, isolation, transduction, expansion ex vivo, and reintroduction into
the patient, uzatresgene autoleucel bind to tumor cells expressing MAGE-A4. This may
result in both inhibition of growth and increased cell death of MAGE-A4-expressing
tumor cells. The tumor-associated antigen MAGE-A4, a member of the MAGE-A family of
cancer testis antigens, is overexpressed by a variety of cancer cell types. Co-expression
of CD8alpha may broaden the immune response against tumors and increase antitumor
activity by converting CD4 helper T-cells into CD8 cytotoxic T-cells.;
