The current standard of care is endoscopic biopsy where the pathologist will visualize the tissue under a microscope to interpret diagnosis. Another goal of this study is to understand tolerance of the procedure so it might be used in an at-home setting.","This study seeks to determine the ability of a minimally invasive capsule-string device, the EnteroTracker®, to capture biomarkers associated with Barrett's Esophagus (BE) and Esophageal Adenocarcinoma (EAC). Identification of biomarkers in samples will support development of this simple-to-use, scalable, method for early screening of EAC, a cancer that accounts for the majority of esophageal cancers in the United States. In this study, the investigators plan to capture esophageal luminal content using the EnteroTracker® from patients with confirmed BE and\u002For EAC (test group) and healthy adults (control group). Samples will then be analyzed for series of biomarkers associated with BE and\u002For EAC. The investigators will test the hypothesis that the EnteroTracker® is able to capture biomarkers of interest in subjects with BE and EAC compared to healthy controls. To address this hypothesis, the investigators propose a pilot study with the following two specific aims. Evaluate the ability and tolerability of the EnteroTracker® to capture esophageal mucosal samples in adults with BE and\u002For EAC as well as controls and determine the ability of the EnteroTracker®-obtained BE\u002FEAC biomarkers to distinguish between BE and\u002For EAC from control subjects.",[19,20],"Barrett Esophagus","Esophageal Cancer",[],"INTERVENTIONAL","DIAGNOSTIC",[25],"NA",{"count":27,"type":28},60,"ESTIMATED",[30],{"type":31,"name":32,"description":33,"armGroupLabels":34},"DEVICE","EnteroTracker","The EnteroTracker® is a capsule device that includes an absorbent string.",[35],"Enterotracker",[37,41,44],{"measure":38,"description":39,"timeFrame":40},"Study Esophageal Mucosal Samples using Enterotracker Device","Capture esophageal mucosal samples in at least 50% of the test subjects using the EnteroTracker®.","2 years",{"measure":42,"description":43,"timeFrame":40},"Testing Tolerability via \"Post-Procedure Tolerability Survey\"","At least 50% of subjects describe the EnteroTracker® as \"Satisfactory\" from taking a \"Post-Procedure Tolerability Survey\".",{"measure":45,"description":46,"timeFrame":40},"Testing difference in Biomarkers between Control and BE\u002FEAC patients","At least one biomarker differentiated between BE\u002FEAC patients and control subjects in at least 50% of test subjects.
