Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to evaluate the Endosign capsule sponge test as a novel surveillance method in patients with an ultralong-segment Barrett's esophagus.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

In this study we will investigate the concordance between the Endosign capsule sponge test and esophagogastroduodenoscopy (EGD) by an expert endoscopist to detect dysplasia and/or esophageal adenocarcinoma (EAC) in patients with an ultralong-segment Barrett's esophagus. Patients will receive both the Endosign test and an EGD, after which we will compare both outcomes. To detect dysplasia and/or EAC on the cells collected by the Endosign test, we will look at cellular atypia and use p53 immunohistochemistry and novel biomarkers. In the future the Endosign test could perhaps replace EGD in the surveillance of Barrett's esophagus patients.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Study group

Subjects will receive the EndoSign test prior to their scheduled clinically indicated upper endoscopy by an expert endoscopist, per routine standard of care. Additional biopsies will be taken and 10cc of blood will be collected from the cannula used for sedation. Subjects will also receive three questionnaires regarding baseline characteristics, gastrointestinal symptoms and acceptability.

Group Type EXPERIMENTAL

EndoSign

Intervention Type DEVICE

The EndoSign cell collection device is a non-endoscopic capsule sponge device used to collect pan-esophageal samples.

The Endosign procedure consists of an expandable, spherical mesh, which is attached to a string and contained within a soluble capsule. Seven minutes after swallowing (once the capsule has dissolved), the spherical mesh, which measures around 3cm in diameter is retrieved by pulling on the string. Upon retrieval the capsule-sponge scrapes against the surface of the top of the stomach and esophagus and collects epithelial cells. The capsule-sponge sample is then placed into a preservative fluid and the specimen is processed for molecular tests.
