About this study
Official title: A Multicenter, Prospective, Open-Label Registry Study of the Utilization of EsoGuard, on Samples Collected Using EsoCheck, in an At-Risk Population Undergoing Standard of Care Screening for, and Management of, Previously Undiagnosed Barrett's Esophagus and/or Esophageal Adenocarcinoma
This is a multicenter, prospective, observational study designed to capture a limited set of data consisting of diagnostic test results and clinical management information on subjects who undergo EC/EG to assess for the presence of BE/EAC. Once sufficient time has elapsed for EsoGuard results to be available, as well as for any subsequent clinical evaluation to have been performed (e.g., upper endoscopy and any initial therapeutic management), study staff will obtain the desired information and record it in an electronic data collection (EDC) system, pertaining to subject demographics, pertinent medical history, and risk factors for BE or EAC as well as (1) information about the EsoCheck cell collection procedure and patient tolerance, (2) EsoGuard test result; (3) initial clinical management including upper endoscopy, if performed, and diagnosis (as determined by the endoscopist and the pathologist assessing any biopsies taken.
For subjects endoscopically confirmed with intestinal metaplasia, dysplasia, or cancer, the registry will collect additional clinical management and/or a therapeutic procedure(s) performed and other mid- to long-term outcomes.

For subjects who are negative for BE/EAC via EsoGuard or negative for BE/EAC via EGD will be offered the option of longer-term follow-up in the form of intermittent wellness checks.
The time point for collecting such information shall be fluid, depending on the time course of care provided subsequent to the EsoGuard result being available. Subject participation duration is dependent on EsoGuard results, physician referral, EGD results (if referred) and participation in long-term follow-up. If EG results are negative and subject is not referred for an EGD, participation could last 1 month. If a subject is confirmed with BE/EAC, participation may continue beyond this minimum for an indefinite period, with no predetermined maximum duration.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
EsoCheck®Device
EsoCheck® (EC) is an FDA 510(k) cleared device that is indicated for use in the collection and retrieval of surface cells of the esophagus in the general population 12 years of age and older.
EsoGuard®Diagnostic test
EsoGuard® is a DNA assay which examines for the presence of cytosine methylation at 31 different genomic locations on the vimentin (VIM) and Cyclin-A1 (CCNA1) genes. Using EsoCheck and EsoGuard in combination may offer an accurate, lower cost, non-invasive, approach to screen for Barrett's Esophagus (BE) with and without dysplasia, and for esophageal adenocarcinoma (EAC).
What is being measured
The primary outcome is the main question the study is designed to answer.
Subsequent Clinical Management Following EsoGuard Testing
Proportion of subjects who undergo a clinically relevant management action following receipt of an EsoGuard result, including referral for esophagogastroduodenoscopy (EGD), surveillance, therapeutic intervention, or other physician-directed management. Clinical management decisions are collected as part of routine clinical care.
Measured: Up to 12 months following EsoGuard testing
Secondary outcomes (6)
Endoscopic Confirmation of Barrett's Esophagus and/or Esophageal Neoplasia
Proportion of subjects with a completed EGD and pathology assessment confirming Barrett's esophagus (BE), dysplasia, esophageal adenocarcinoma (EAC), or other relevant esophageal findings following EsoGuard testing.
Measured: Up to 12 months following EsoGuard testing
Disease Stage at Endoscopic Diagnosis
Histologic and/or clinical stage of Barrett's esophagus, dysplasia, or esophageal neoplasia identified during clinically indicated endoscopic evaluation following EsoGuard testing.
Measured: Up to 12 months following EsoGuard testing
Therapeutic Interventions Following EsoGuard Testing
Proportion of subjects who undergo therapeutic intervention for BE, dysplasia, or EAC, including endoscopic eradication therapy, surgical intervention, pharmacologic treatment, or other standard-of-care management.
Measured: Up to 12 months following EsoGuard testing
Surveillance Utilization Following EsoGuard Testing
Proportion of subjects who undergo follow-up surveillance procedures or monitoring for BE/EAC according to routine clinical practice.
Measured: Up to 24 months following EsoGuard testing
Incident Detection of Barrett's Esophagus or Esophageal Adenocarcinoma
Number and proportion of subjects initially considered negative for BE/EAC who subsequently receive a diagnosis of BE, dysplasia, or EAC during follow-up.
Measured: Up to 24 months following EsoGuard testing
Disease Progression or Resolution
Among subjects with identified esophageal disease, assessment of disease progression, stability, or resolution based on available endoscopic, histologic, and clinical follow-up data.
Measured: Up to 24 months following EsoGuard testing
