Histocompatibility Leukocyte Antigen (HLA)-A*2402 Restricted Peptide Vaccine Therapy in Patients With Esophageal Cancer
Phase I/II Study of Multiple-Vaccine Therapy Using Epitope Peptide Restricted to HLA-A*2402 in Treating Patients With Refractory Esophageal Cancer

The purpose of this study is to evaluate the safety and time to progression of HLA-A*2402 restricted epitope peptides URLC10, TTK, and KOC1, emulsified with Montanide ISA 51.

URLC10, KOC1 and TTK have been identified as cancer specific molecules especially in non small cell lung cancer using genome-wide expression profile analysis by cDNA microarray technique. In a prior study, it has been shown that URLC10, KOC1 and TTK are upregulated in human esophageal tumors. We identified that peptides derived from these proteins significantly induce the effective tumor specific CTL response in vitro and vivo. According to these findings, in this trial, we evaluate the safety, immunological and clinical response of those peptides. Patients will be vaccinated twice a week for 8 weeks. On each vaccination day, the URLC10 peptide (1mg), KOC1 peptide (1mg), and TTK peptide (1mg) mixed with Montanide ISA 51 will be administered by subcutaneous injection. Repeated cycles of vaccine 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 vaccines. In the following phase II study, we evaluate the immunological and clinical response of this vaccine therapy.
