Autologous MAGE-C2-specific HLA-A2-restricted TCR T-lymphocytes

**Semantic type:** Cell|Pharmacologic Substance

**Definition:** A preparation of autologous T-lymphocytes genetically modified to express a T-cell receptor (TCR) specific for human leukocyte antigen (HLA)-A2-restricted, melanoma-associated antigen C2 (MAGE-C2; MC2), ALK epitope, with potential antineoplastic activity. Peripheral blood mononuclear cells (PBMCs) are isolated from a patient, transduced with an anti-MAGE-C2-HLA-A2 restricted TCR, expanded ex vivo, and reintroduced into the HLA-A2-positive patient. Upon reintroduction, the autologous MAGE-C2-specific HLA-A2-restricted TCR T-lymphocytes bind to tumor cells expressing the MAGE-C2 antigen, which may induce cell death in and halt the growth of MAGE-C2-expressing cancer cells. MAGE-C2, a cancer/testis tumor-associated antigen (CT-TAA), is overexpressed by a variety of cancer cell types.

**Synonyms:** - Autologous MAGE-C2/HLA-A2 TCR T-cells - Autologous MC2 TCR T Cells
