Allogeneic Third-party Suicide Gene-transduced Anti-HLA-DPB1*0401 CD4+ T-cells CTL 19

**Semantic type:** Cell|Pharmacologic Substance

**Definition:** A preparation of allogeneic, third-party, CD4+ T-lymphocytes that specifically recognizes the human leukocyte antigen (HLA)-DPB1*0401 and transduced with a suicide gene, with potential antineoplastic activity. Upon administration, allogeneic third-party suicide gene-transduced anti-HLA-DPB1*0401 CD4+ T-cells CTL 19 specifically target and kill HLA-DPB1*0401-positive leukemic cells. The suicide gene causes the destruction of the T-cell clone upon the administration and presence of ganciclovir, which enhances the safety of the agent. HLA-DP is expressed by many leukemic cells.

**Synonyms:** - CTL 19 - CTL-19 - CTL19
