Arms Assigned Interventions
Experimental: Phase I study Biological: VEGFR2-169 and gemcitabine
Escalating doses of VEGFR2-169 will be administered by subcutaneous injection on days 1,8,15 and 22 of each 28-day treatment cycles(doses of 0.5,1.0,2.0mg/body are planned). Gemcitabine will be administered intravenously at a fixed dose of 1000mg/m2 on days 1,8 and 15. Repeated cycles of VEGFR2-169 and gemcitabine will be administered until patients develop progressive disease or unacceptable toxicity,or for maximum 2 cycles, whichever occurs first.

Detailed Description:
Vascular endothelial growth factor receptor 2(VEGFR2) is essential target for tumor angiogenesis, and VEGFR2-169 induces specific Cytotoxic T lymphocytes (CTL) against VEGFR2 expressed targets. VEGFR2-169 shows strong anti-tumor effects restricted to HLA-A*2402 in vitro, and this peptide induces CTL from cancer patients. 60% in Japanese population have HLA-A*2402. VEGFR2-169 is suitable for clinical trial, and gemcitabine has been approved against pancreatic cancer. Gemcitabine is reported to improve immune-response, therefore synergistic effect between vaccine therapy and chemotherapy will be expected. In this clinical trial, we evaluate the safety, tolerability and immune response of different doses of VEGFR2-169 emulsified with Montanide ISA 51 in combination with gemcitabine and to determine the recommended phase II dose of peptide.
