NCIt synonyms : WT-1 Analog Peptide Vaccine SLS-001; SLS-001;
NCIt definition : A peptide cancer vaccine comprised of four peptide chains derived from the Wilms'
tumor gene 1 (WT1) protein, with potential immunomodulating and antineoplastic activities.
Upon administration, galinpepimut-S, which is comprised of one WT1-derived peptide
(WT-A1) that may stimulate CD8-positive T-cell responses; two WT1 peptides (WT1-427
long, WT1-331 long) that may stimulate CD4-positive T-cell responses; and one modified
peptide (WT1-122A1 long) that may stimulate both CD4-positive and CD8-positive T-cells,
may elicit a targeted innate immune response against WT1-expressing tumor cells. WT1
protein, a zinc finger DNA-binding protein and transcription factor, is overexpressed
in leukemic cells and in many non-hematological solid tumors.;
