NCIt definition : A preparation of genetically modified, multi-antigen-targeted autologous T-lymphocytes,
tethered with the human immunostimulatory cytokine interleukin-12 (IL-12), with potential
immunostimulating and antineoplastic activities. RPTR 168 is prepared from monocyte-derived
dendritic cells (moDCs) that are pulsed with five tumor-associated antigens (TAAs)
to expand cytotoxic T-lymphocytes (CTLs) that are subsequently loaded with IL-12.
Upon administration, the autologous IL-12/multi-targeted primed T-cells RPTR 168 specifically
target tumor cells expressing the five TAAs, which lead to a specific cytotoxic T-lymphocyte
(CTL)-mediated killing of these tumor cells. In addition, IL-12 expression activates
the immune system by promoting the secretion of interferon-gamma (IFN-g), activating
natural killer cells (NKs), and inducing CTL responses, which may further increase
tumor cell death and decrease tumor cell proliferation.;
