A Study With Peptide Vaccination in Treating Patients With Esophageal Cancer

2014-08-27 03:18:40 | BioPortfolio

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).

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.

Medical and Biotech [MESH] Definitions

Tumors or cancer of the ESOPHAGUS.

A pathological condition characterized by the presence of a number of ESOPHAGEAL DIVERTICULA in the ESOPHAGUS.

Circular innermost layer of the ESOPHAGUS wall that mediates esophageal PERISTALSIS which pushes ingested food bolus toward the stomach.

Disorders affecting the motor function of the UPPER ESOPHAGEAL SPHINCTER; LOWER ESOPHAGEAL SPHINCTER; the ESOPHAGUS body, or a combination of these parts. The failure of the sphincters to maintain a tonic pressure may result in gastric reflux of food and acid into the esophagus (GASTROESOPHAGEAL REFLUX). Other disorders include hypermotility (spastic disorders) and markedly increased amplitude in contraction (nutcracker esophagus).

The production of PEPTIDES or PROTEINS by the constituents of a living organism. The biosynthesis of proteins on RIBOSOMES following an RNA template is termed translation (TRANSLATION, GENETIC). There are other, non-ribosomal peptide biosynthesis (PEPTIDE BIOSYNTHESIS, NUCLEIC ACID-INDEPENDENT) mechanisms carried out by PEPTIDE SYNTHASES and PEPTIDYLTRANSFERASES. Further modifications of peptide chains yield functional peptide and protein molecules.
