Primary Outcome Measures:
  • safety of the cyclophosphamide combined tumor specific epitope peptide cocktail [ Time Frame: 2 years ]

Secondary Outcome Measures:
  • immunological efficacies and clinical efficacies of the cyclophosphamide combined tumor specific epitope peptides cocktail [ Time Frame: 2.5 years ]

Enrollment: 18
Study Start Date: November 2007
Study Completion Date: March 2010
Primary Completion Date: March 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: 1
cyclophosphamide dose escalation, level 1:150mg/m2,level 2: 300mg/m2, level 3: 300mg/m2x2, with 5 kinds o tumor specific antigen peptides followed by low dose IL-2, 6 patients will be enrolled for each level.
Biological: 5 peptide vaccines of KOC1, TTK, CO16, DEPDC1, MPHOSPH1
1mg each of 5 peptides with IFA. 4 weekly s.c. administration.
Other Name: 5 peptide cocktail

Detailed Description:
KOC1, TTK, CO16(URLC10), DEPDC1, MPHOSPH1 have been identified using genome-wide expression profile analysis by the use of cDNA microarray in the previous studies. The investigators have determined the HLA-A*2402 restricted epitope peptides respectively derived from KOC1, TTK, CO16(URLC10), DEPDC1, and MPHOSPH1 showed strong INF-gamma production when stimulated with the appropriate targets expressing the appropriate protein and HLA-A*2402. Furthermore, when vaccinated these peptides, specific CTLs were determined after the vaccination. Therefore the investigators focused on the prevention of further expansion of the solid tumors highly expressing these 5 proteins using these 5 peptides.
