Primary Outcome Measures:
  • Safety (toxicities as assessed by NCI CTCAE version 3) [ Time Frame: 2 months ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:

Estimated Enrollment: 18
Study Start Date: May 2007
Estimated Study Completion Date: March 2008
Primary Completion Date: January 2008 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Phase 1 Biological: RNF43-721
Doses of 0.5mg, 1.0mg, 3.0mg/body/week
Other Name: S-1/CPT-11

Detailed Description:

RNF43 is a cancer testis antigen which express widely in colorectal cancer tissue but not in normal organs. RNF43-721 induces HLA A24 restricted specific cytotoxic T lymphocytes (CTL) against RNF43 expressed target. S-1/CPT-11 chemotherapy is performed unresectable advanced colorectal cancer in Japan and is reported to be obtained almost the same result compared with FOLFOX or FOLFIRI as first-line chemotherapy for advanced colorectal cancer. Because synergistic effect between vaccine therapy and chemotherapy will be expected, we plan phase I study to evaluate the safety and immune response of different doses of RNF43-721 emulsified with Montanide ISA 51 in combination with S-1/CPT-11 chemotherapy.
