NCIt definition : A peptide-based cancer vaccine consisting of amino acid residues 26 through 35 of
MART-1 (melanoma antigen recognized by T-cells-1) with a leucine substitution at amino
acid position 27 to improve immunogenicity. Upon administration, MART-1:26-35(27L)
peptide vaccine may induce a cytotoxic T-lymphocyte (CTL) response against MART-1-expressing
tumor cells, resulting in decreased tumor growth. The tumor-associated antigen (TAA)
MART-1 may be overexpressed on melanoma cancer cells.;
