NCIt synonyms : ICT-121 DC Vaccine; CD133 Peptides-pulsed Autologous DC Vaccine; CD133 Peptides-pulsed Autologous Dendritic Cell Vaccine;
NCIt definition : A cell-based cancer vaccine composed of autologous dendritic cells (DCs) pulsed with
purified peptides derived from the tumor-associated antigen (TAA) CD133, with potential
immunostimulatory and antineoplastic activities. Upon leukapheresis, monocytes are
differentiated into DCs and are mixed with the CD133 peptides. Upon intradermal re-administration
of the ICT-121 DC vaccine, the DCs present the CD133 peptides to the immune system,
which stimulates the immune system to induce a specific cytotoxic T-lymphocyte (CTL)
response against CD133-expressing tumor cells and leads to tumor cell lysis. CD133
is overexpressed on various types of cancer cells; its overexpression is correlated
with increased resistance to chemotherapy.;
