A synthetic tumor-associated peptide (TUMAP)-based cancer vaccine directed against colorectal cancer with potential immunostimulatory and antineoplastic activities. Synthetic colorectal tumor-associated peptides vaccine IMA910 contains 13 different synthetic tumor-associated peptides (TUMAPs), each of which represents a tumor associated antigen (TAA) specific for colorectal cancer. Upon administration, this agent may elicit a cytotoxic T-lymphocyte (CTL) response against colorectal tumors expressing these TAAs, which may result in a reduction in colorectal tumor cell proliferation.
