NCIt definition : A preparation of autologous T-lymphocytes that have been transduced with a lentiviral
vector to express a T-cell receptor mimetic (TCRm) antibody synthesized by a proprietary
phage display platform, targeting the immunogenetic human tumor-associated antigen
(TAA) alpha-fetoprotein (AFP) complexed with human leukocyte antigen (HLA)-A*02 (HLA-A*02/AFP),
with potential antineoplastic and immunomodulatory activities. Upon administration,
the autologous anti-HLA-A*02/AFP TCRm-expressing T-cells ET140202 specifically recognize
and selectively bind to AFP peptides presented by HLA-A*02. This results in cytotoxic
T-lymphocyte (CTL)-mediated elimination of AFP-expressing tumor cells. AFP, an intracellularly
expressed fetal glycoprotein rarely expressed in adult tissues, is overexpressed in
certain tumors of endodermal origin and plays a key role in tumor cell proliferation
and survival. AFP is processed into peptides and presented by class I major histocompatibility
complexes (MHCs) on the surface of tumor cells.;
