Non-Endoscopic Detection of Barrett's Esophagus Using Methylation Biomarkers on EndoSign® Cell Collection Device Samples

Summary

This study is looking at cells collected from the esophagus using a diagnostic device called the EndoSign® Cell Collection Device (a sponge on a thread). Subjects swallow a capsule, which dissolves in the stomach and releases a sponge that collects cells from the esophagus as the sponge is withdrawn using the thread. These cells will be tested to check for a condition called "Barrett's Esophagus." The cells from the sponge will be tested using Cyted Health biomarkers and compared to the results from a regular endoscopy and any biopsies that are taken. To do this, we need sponge samples from people who might have Barrett's Esophagus based on their risk factors, and from people with Barrett's Esophagus. Subjects will have one visit to have the Endosign Cell Collection Device administered prior to having a standard of care endoscopy. They will answer some questions about their medical history and experience with the cell collection procedure as part of the study. Data will be collected from medical records including post-endoscopy.

Eligibility

* Obesity (BMI greater than or equal to 30 kg/m2)
* Male
* Non-Hispanic White

Exclusion Criteria

* Previous EGD for BE, with no BE identified
* Known BE or EAC

* Known or suspected gastric or esophageal varices
* Known or suspected portal hypertension
* Taking anti-thrombotic medications that cannot be discontinued
