Histocompatibility Leukocyte Antigen (HLA)-A*0201 Restricted Peptide Vaccine Therapy in Patients With Non-Small Cell Lung Cancer
- Conditions
- Non Small Cell Lung Cancer
- Interventions
- Biological: URLC10, VEGFR1 and VEGFR2
- Registration Number
- NCT00673777
- Lead Sponsor
- Tokyo University
- Brief Summary
The purpose of this study is to evaluate the safety and time to progression of HLA-A\*0201 restricted epitope peptides URLC10, VEGFR1 and VEGFR2 emulsified with Montanide ISA 51.
- Detailed Description
URLC10 has been identified as cancer specific molecules especially in non small cell lung cancer using genome-wide expression profile analysis by cDNA microarray technique. We have determined the HLA-A\*0201 restricted epitope peptides derived from these molecules. We also tend to use the peptides targeting to tumor angiogenesis. 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, immunological and clinical response of those peptides. Patients will be vaccinated twice a week for 8 weeks. On each vaccination day, the URLC10-117 peptide(1mg), VEGFR1 peptide(1mg) and VEGFR2 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 vaccine. In the following phase II study, we evaluate the immunological and clinical response of this vaccine therapy.
