NCIt synonyms : Autologous CD8 and CD4 T-cells transduced with TCR A2-MCC1; FH-MCVA2TCR Autologous CD8 and CD4 T-cells Transduced with TCR A2-MCC1;
NCIt definition : A preparation of autologous CD4 and CD62L-expressing CD8 T-cells transduced with
a third generation lentiviral vector (LV) to express the high affinity T-cell receptor
(TCR) A2 -MCC1, specific for the human leukocyte antigen (HLA)-A02-restricted Merkel
cell polyomavirus (MCPyV; MCV) viral oncoprotein, with potential immunomodulating
and antineoplastic activities. Upon reintroduction into the patient, the autologous
MCPyV-specific HLA-A02-restricted TCR-transduced CD8 and CD4 T-cells FH-MCVA2TCR
selectively bind to the KLLEIAPNC epitope (KLL epitope) within the MCPyV viral oncoprotein.
This results in cytotoxic T-lymphocyte (CTL)-mediated elimination of tumor cells expressing
the MCPyV viral oncoprotein. Additionally, tumor-specific HLA-A02-restricted CD4
cells promote class I-restricted CD8 proliferation, survival and effector functions
by producing interleukin (IL)-2 and facilitating the activation of dendritic cells
(DCs). MCPyV viral oncoprotein is highly expressed in Merkel cell carcinoma (MCC)
caused by MCPyV.;
