NCIt definition : Human autologous T-lymphocytes genetically modified to express a T-cell receptor (TCR)
that specifically targets human melanoma-associated antigen A3 (MAGE-A3) and MAGE-A6
(MAGEA3/A6; MAGE-A3/A6), with potential antineoplastic activity. Peripheral blood
mononuclear cells (PBMCs) are isolated from a patient, transduced with a gene expressing
a TCR specific for the MAGE-A3/A6 antigens, expanded ex vivo, and reintroduced into
the patient. Then, the autologous MAGE-A3/A6-specific TCR gene engineered lymphocytes
KITE-718 target and bind to tumor cells expressing the MAGE-A3 and/or MAGE-A6 antigens.
This halts the growth of and kills MAGE-A3/A6-expressing cancer cells. The tumor-associated
antigens MAGE-A3 and MAGE-A6 are overexpressed on a variety of tumor cell types.;
