Trial Information

Phase 1 Study of Multiple Peptide Vaccine Therapy and GM-CSF in Treating Patients With Esophageal Cancer


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.

or in the situation where effective therapy is not available, or has been refused due
to severe adverse effects of chemotherapy

x the institutional normal upper limits AST, ALT, ALP ≤ 2.5 x the
institutional normal upper limits Creatinine ≤ 1.5 x the institutional normal upper
limits

7. Patients must be HLA-A2402

8. Primary lesion of esophageal cancer must express LY6K

9. Able and willing to give valid written informed consent

Exclusion Criteria:

1. Pregnancy (women of childbearing potential: Refusal or inability to use effective
means of contraception)

2. Breastfeeding

3. Serious infections requiring antibiotics

4. Patient with peptic ulcer disease
