Brief Summary:
The purpose of this study is to evaluate overall survival and immunological monitoring for peptide vaccination therapy using novel cancer testis antigens for locally advanced, recurrent, or metastatic esophageal squamous cell carcinoma (ESCC).

Condition or disease Intervention/treatment Phase
Esophageal Cancer Biological: peptide Phase 2

Detailed Description:
The phase I vaccination study using peptides derived from TTK, LY6K, and IMP-3 for locally advanced, recurrent or metastatic esophageal squamous cell carcinoma (ESCC) who had failed for the standard therapy indicated that the vaccine treatment were well tolerated and feasible, and that antigen-specific T cell responses were strongly induced by the vaccination with some objective clinical responses. Thus, we are currently initiating the randomized phase II clinical vaccination study for the same cohort with ESCC to evaluate the survival benefit of the cancer vaccination.
