Definition

A peptide cancer vaccine consisting of a combination of six synthetic polypeptides directed against cancer testis antigens (CTAs) frequently expressed in colorectal cancers, with potential antineoplastic and immunostimulatory activities. Colorectal cancer peptide vaccine PolyPEPI1018 potentially elicits a cytotoxic T-lymphocyte response against colorectal tumors expressing the CTAs associated with the vaccine, which may result in a reduction in tumor cell proliferation.
