Clinical Trial Summary

The purpose of this study is to develop a method to detect Barrett's esophagus (BE) in individuals with a new office-based diagnostic test.

Description:

This study will investigate whether using EsoCheck/EsoGuard(EC/EG) can detect BE in individuals at risk for BE who are currently not being detected and are not undergoing routine esophago-gastro-duodenoscopy (EGD) BE can only be diagnosed by performing upper endoscopy. Up to 500 adults who have risk factors for BE but do not have chronic heartburn or regurgitation will be enrolled in this study. This will include the EsoCheck/EsoGuard determination along with the upper endoscopy for qualifying EsoGuard negative subjects

Eligibility

Inclusion Criteria:

• No known coagulopathy, no known esophageal varices.

• Absence of chronic GERD, defined as five or more years of heartburn or regurgitation with symptoms at least once a week when not on medications for GERD symptoms.
• Subjects to qualify must meet criterion 3, be over age 50, and have two additional risk factors for BE (white race, central obesity defined as waist size >35 inches for women and >40 inches for men, male gender, current smoker or smoking history >10 pack years, confirmed family history in at least two members with one being a first degree relative).

Exclusion Criteria:

• Known history of esophageal varices or esophageal stricture
• Any contraindication, as deemed inInvestigator's medical judgment, to undergoing the EsoCheck procedure, undergoing the EGDprocedure,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

Intervention

Diagnostic Test:
• EsoCheck/EsoGuard (EC/EG)
EC is a swallowed capsule on a tethered catheter that obtains a touch sample of the distal esophagus. The obtained sample is placed in a buffer and sent to a diagnostics lab for testing of methylated markers from extracted DNA. EG is a methylated DNA test . A positive EG is associated with Barrett's esophagus at all its stages.
• Esophago-gastro-duodenoscopy (EGD)
SOC diagnostic endoscopic procedure that visualizes the upper part of the gastrointestinal tract down to the duodenum. Tissue samples collected.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Positive predictive value (PPV) of EC/EG in a non-GERD population that has three or more non-GERD risk factors for BE.	PPV of EC/EG in a non-GERD population that has three or more non-GERD risk factors for BE. Participants who are at risk will be offered EC/EG. Those who are positive will undergo subsequent EGD; PPV = (EC/EG positive & EGD positive) / ((EC/EG positive & EGD positive) + (EC/EG positive & EGD negative))	Up to 2 months
Primary	Proportion of participants negative via EC/EG who subsequently are proven negative via EGD	Negative Predictive Value (NPV): Proportion of participants negative via EC/EG who subsequently are proven negative via EGD. This will be measured by offering EGD to a proportion of patients who are EC/EG negative.	Up to 2 months
