Summary

The goal of this clinical trial is to develop a method to detect Barrett's esophagus in individuals with a new office based diagnostic test. Barrett's esophagus is a condition in which the flat pink lining of the swallowing tube that connects the mouth to the stomach (the esophagus) becomes damaged by acid reflux. The main question it aims to answer is: Can this approach demonstrate efficacy for screening of Barrett's esophagus? Participants will: * Participate in a questionnaire. * Undergo a capsule balloon test, called EsoCheck. * Have their EsoCheck sample sent to the laboratory for an EsoGuard test, which is used to detect Barrett's esophagus. * Participants will undergo upper endoscopy as part of standard of care.

Detailed Description

The overall goal of this clinical trial is to eliminate deaths from Esophageal Adenocarcinoma (EAC) by demonstrating the efficacy of a non-endoscopic method for efficient population screening to detect all Barrett's esophagus (BE), the precursor lesion of EAC. EAC is a highly lethal malignancy with less than 20% 5-year survival, and an annual U.S. incidence \> 14,000 that has increased more than 6-fold in the past three decades. Barrett's esophagus, a pre-malignant metaplasia/neoplasia, is the precursor lesion of EAC, but is currently detectable only when patients undergo upper endoscopy (EGD). Despite Guideline recommendations for EGD in chronic GERD (gastrointestinal reflux disease) patients, barriers to EGD that include cost, sedation, and lack of acceptance, have so severely limited screening that antecedent BE remains undetected in over 95% of EAC cases. A major advance in EAC prevention was made by developing a non- endoscopic biomarker based method for detecting BE. The technology consists of an encapsulated swallowable balloon (EsoCheck) enabling a 5 minute non-endoscopic sampling of the esophagus, combined with a methylated DNA panel that detects esophageal neoplasia (EsoGuard). The research team validated the \> 90% sensitivity and specificity of EC+EG testing in the population of individuals who have symptomatic GERD, and who account for 60% of EAC cases. In this new proposal, the research team plans to double the impact of this technology to detect nearly all individuals harboring BE, by proving the EC+EG technology is so robust that it further enables screening a population of high risk, but asymptomatic, non-GERD individuals who account for the remaining 40% of EAC cases, but who fall totally outside of all current screening guidelines.

Eligibility Criteria

Age Range: 50 years to No maximum

Inclusion Criteria: Patients undergoing screening colonoscopy are an accessible cohort for BE screening and are also a reasonable representation of the general population. Permission will be obtained from colonoscopy physicians for researchers to contact and recruit patients for this study. Patients without GERD, who are at risk for BE, and who have not had a prior EGD, will be recruited prior to or at the time of scheduled colonoscopy.(9) Those eligible will be: * Adults who have not had prior EGD within past ten years, and are able to provide informed consent, and who have: * No known coagulopathy, no known esophageal varices, not on chronic anticoagulation therapy, and have: * No significant dysphagia or odynophagia; but who do have: * Absence of GERD (absence of weekly heartburn or regurgitation, not on medications for GERD), and are: * Adults \> age 50, who also have two or more added risk factors for BE from the set of: central obesity (waist size \> 35 inches for women and \> 40 inches for men), current smoker or smoking history \> 10 pack years, white race, male sex, confirmed history of BE/EAC in at least two family members, with one a first degree relative. While BE is most highly prevalent in white males, a black female over age 50 with obesity and a positive smoking history would also be at increased BE risk and would equally meet eligibility criteria. * Subjects must have the ability to understand and the willingness to sign a written informed consent document. * Subjects must have the ability to understand and the willingness to sign a written informed consent document. Exclusion Criteria: * History of prior EGD procedure in past ten years * Inability to provide written informed consent * History of weekly of more frequent heartburn or regurgitation for five or more years * On anti-coagulant drug(s) that cannot be temporarily discontinued or coagulopathy with INR \> 1.5 * Known history of esophageal varices or esophageal stricture * Any contraindication, as deemed in Investigator's medical judgment, to undergoing the EsoCheck procedure, undergoing the EGD procedure, and/or having biopsies taken, including but not limited to due to comorbidities such as coagulopathy or a known history of esophageal diverticula, esophageal fistula and/or esophageal ulceration * History of difficulty swallowing (dysphagia) or painful swallowing (odynophagia), including swallowing pills * Oropharyngeal tumor * History of esophageal or gastric surgery, with exception of uncomplicated surgical fundoplication procedure
