NCIt definition : A peptide vaccine containing five immunogenic peptide epitopes of the human folate
receptor 1 (FOLR1; FR-alpha), with potential immunomodulating and antineoplastic activities.
Upon intradermal administration, multi-epitope anti-folate receptor peptide vaccine
TPIV 200 may induce a cytotoxic T-lymphocyte (CTL) response against FR-alpha-overexpressing
tumor cells. FR-alpha is a high-affinity folate-binding protein and a member of the
folate receptor family; this receptor is overexpressed in various cancer cell types.;
