NCIt definition : A preparation of autologous T-lymphocytes that are genetically modified with a lentiviral
vector encoding a T-cell receptor (TCR) specific for the tumor-associated antigen
(TAA) preferentially expressed antigen in melanoma (PRAME), with potential antineoplastic
activity. Upon intravenous administration back into the patient, the autologous PRAME-targeting
TCR-engineered T-cells IMA203 specifically recognize and bind to PRAME expressed on
cancer cells, which induces a cytotoxic T-lymphocyte (CTL)-mediated immune response
against the PRAME-expressing cancer cells. PRAME is overexpressed by a variety of
cancer cell types.;
