Trial Identification

Brief Title: The Microenvironment in Barrett's Esophagus

Official Title: Application of the Microbiome and Microenvironment to Novel Non-Endoscopic Screening and Surveillance in Barrett's Esophagus

Study ID: NCT03060642

Study Description

Brief Summary: This study aims to elucidate the relationship between the microbiome, inflammation, and the microenvironment in Barrett's esophagus (BE) and esophageal adenocarcinoma (EAC), with the end goal of developing a non-endoscopic testing strategy based on pathogenic factors to identify patients at highest risk for EAC. To accomplish this the investigators will enroll 100 patients with known BE (50 with dysplasia or EAC) and 50 subjects without BE undergoing upper endoscopy. Prior to endoscopy each subject will undergo three minimally invasive potential screening and surveillance tests: saliva (oral microbiome), breath test (exhaled volatile organic compounds), and tethered capsule sponge sampling (methylated DNA markers). The study will evaluate these novel tests in combination with clinical and anthropometric factors to describe an optimal strategy for BE screening and monitoring.

Detailed Description: The investigators will perform a multi-center cross-sectional study of patients with Barrett's esophagus, with and without associated dysplasia or cancer, and controls without BE. Enrollment of controls will be stratified based on use of proton pump inhibitors (PPIs). The investigators plan to enroll an approximate total of 150 subjects: 100 BE patients (with or without associated dysplasia or cancer) * 50 subjects with non-dysplastic BE * 50 subjects with BE and dysplasia or EAC 50 controls * 25 controls on PPIs (at least once daily) * 25 controls not taking PPIs Various tests will be performed and samples collected on the day of endoscopy. These tests include: saliva samples, electronic nose device testing, tethered capsule sponge testing, dietary questionnaires, and collection of blood and gastrointestinal biosamples. Analyses of this data and samples will then be performed to address the specific aims above.
