Brief Summary

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

This study will evaluate if the sponge capsule device can accurately detect the presence of Barrett's Esophagus and prevalent dysplasia/adenocarcinoma detection, in a screening population, with and without chronic gastroesophageal reflux disease.

Detailed Description

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

The sponge on a string (SOS) device will be safely administered by a non-physician such as a nurse. Novel discriminant methylated DNA markers will be assayed on esophageal cytology specimens obtained from the SOS device to enable detection in Barrett's Esophagus and prevalent dysplasia/adenocarcinoma detection.

Study Groups

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

Screening Population

Those that have gastroesophageal reflux or other risk factors for Barrett's Esophagus will be contacted and if agreeable undergo sponge capsule procedure and fill out questionnaires.

Group Type OTHER

Sponge Capsule

Intervention Type DEVICE

Subjects will swallow sponge capsule and esophageal cells will be collected on deployed sponge.

Upper endoscopy - Barrett's Esophagus

Those that have a diagnosis of Barrett's Esophagus and are scheduled for an upper endoscopy will be approached and if agreeable undergo sponge capsule procedure as well as endoscopic biopsies and brushings of the esophagus.

Group Type OTHER

Sponge Capsule

Intervention Type DEVICE

Subjects will swallow sponge capsule and esophageal cells will be collected on deployed sponge.

Upper endoscopy - No Barrett's Esophagus

Those that have no known Barrett's Esophagus and are scheduled for an upper endoscopy will be approached and if agreeable undergo sponge capsule procedure as well as endoscopic biopsies and brushings of the esophagus.

Group Type OTHER

Sponge Capsule

Intervention Type DEVICE

Subjects will swallow sponge capsule and esophageal cells will be collected on deployed sponge.

* Patients on oral anticoagulation including Coumadin, Warfarin (this does not apply to the brushings/biopsies only portion of the study).
* Patients on antiplatelet agents including Clopidogrel, unless discontinued for three to five days prior to the sponge procedure.
* Patients on oral thrombin inhibitors including Dabigatran and oral factor Xa inhibitors such as rivaroxaban, apixaban and edoxaban, unless discontinued for three to five days prior to the sponge procedure.
* Patients with history of known esophageal or gastric varices or cirrhosis.
* Patients with history of surgical esophageal resection for esophageal carcinoma.
* Patients with congenital or acquired bleeding diatheses.
* Patients with a history of esophageal squamous dysplasia.
* Patient has known carcinoma of the foregut (pancreatic, bile duct, ampullary, stomach, or duodenum) within 5 years prior to study enrollment.
* Patient has received chemotherapy class drugs or radiation to treat mediastinal or esophageal cancer.
