Primary Outcome Measures:
  • Toxicity of multiple peptide vaccinations [ Time Frame: one year ]

Secondary Outcome Measures:
  • Immune responses including LY6K, VEGFR1 and VEGFR2 specific T cells [ Time Frame: one year ]

Enrollment: 6
Study Start Date: October 2007
Study Completion Date: June 2008
Primary Completion Date: May 2008 (Final data collection date for primary outcome measure)
Intervention Details:
    Biological: LY6K, VEGFR1, VEGFR2
    1 mg/body every two week with GM-CSF, 4 cycles
Detailed Description:
LY6K (lymphocyte antigen 6 complex, locus K) was identified as a new target of tumor associated antigen using cDNA microarray technologies combined with the expression profiles of normal and cancer tissues. On the other hand, anti-angiogenic therapy is now considered to be one of promising approaches to treat of cancer. In this clinical trial, we evaluate the safety and immune responses of multiple peptide cocktail including LY6K and vascular endothelial growth factor receptor 1 (VEGFR1) and vascular endothelial growth factor receptor 2 (VEGFR2) together with IFA and GM-CSF as immunoadjuvants in patients who had LY6K expressed primary esophageal cancer. Toxicity profiles will be monitored, and antigen specific T cell responses will be described.
