Study Description
Brief Summary:
The purpose of this study is to evaluate the safety and time to progression of HLA-A*0201 restricted epitope peptides VEGFR1 and VEGFR2 emulsified with Montanide ISA 51 in combination with Tegafur/Uracil/Folinate chemotherapy.

Condition or disease Intervention/treatment Phase
Colorectal Cancer Colon Cancer Rectal Cancer Biological: VEGFR1 and VEGFR2 Phase 1 Phase 2

Detailed Description:
VEGF receptor 1 and 2 are essential targets to tumor angiogenesis, and we identified that peptides derived from these receptors significantly induce the effective tumor specific CTL response in vitro and vivo. According to these findings, in this trial, we evaluate the safety, clinical and immunological response of those peptides. Patients will be vaccinated twice a week for 8 weeks. On each vaccination day, VEGFR1 peptide (1mg) and VEGFR2 peptide (1mg) mixed with Montanide ISA 51 will be administered by subcutaneous injection. The patients will also receive oral chemotherapy (Tegafur/Uracil/Folinate) simultaneously. Repeated cycles of the vaccine and the chemotherapy will be administered until patients develop progressive disease or unacceptable toxicity, whichever occurs first. In the phase I study, we evaluate the safety and tolerability of these peptide vaccine. In the following phase II study, we evaluate the immunological and clinical response of this vaccine therapy.
