Definition

A preparation of human autologous T lymphocytes transduced with a viral vector encoding for a T-cell receptor (TCR) specific for human alpha-fetoprotein (AFP), with potential antineoplastic activity. Following administration, the TCR-specific, alpha fetoprotein-enhanced autologous T lymphocytes recognize and bind to AFP antigen-positive cells, which results in lysis and killing of AFP-positive cancer cells. AFP is overexpressed in a variety of cancers.
