cancer peptide vaccine S-588410

A cancer peptide vaccine containing five human leukocyte antigen (HLA)-A*2402-restricted epitope peptides derived from as of yet not disclosed oncoantigens, with potential immunostimulating and antineoplastic activities. Upon administration of the cancer peptide vaccine S-588410, the peptides may stimulate a cytotoxic T-lymphocyte (CTL) response against cancer cells expressing the antigens. This decreases proliferation of susceptible tumor cells.
