NCT03961945

Brief Summary

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.

Outcome Measures

Primary Outcomes (3)

  • Aim 1 - Screening Population

    To measure the positive and negative predictive value of the sponge capsule Barrett's esophagus test in a screening population.

    5 years

  • Aim 2 - Case/Control Population BE Detection

    Compare the sensitivity and specificity of a predetermined BE prediction algorithm for those with and without GERD and assess the influence of other covariates (age, sex, ever smoking, ethnicity and BMI) on this algorithm.

    5 years

  • Aim 3 - Dysplasia Detection Sensitivity and Specificity

    Measure the sensitivity and specificity of a predetermined MDM panel assayed on SOS specimens from BE patients identified in Aims 1 and 2, for the detection of HGD /EAC, using surveillance histology as the criterion standard.

    5 years

Secondary Outcomes (4)

  • Aim 1 - Screening Population Predictive Value

    5 years

  • Aim 1 - Screening Population Safety and Tolerability of sponge capsule procedure

    5 years

  • Aim 2 - Case/Control Population Sensitivity and Specificity

    5 years

  • Aim 3 - Dysplasia Detection Rate of Missed Dysplasia

    5 years

Study Arms (3)

Screening Population

OTHER

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.

Device: Sponge Capsule

Upper endoscopy - Barrett's Esophagus

OTHER

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.

Device: Sponge Capsule

Upper endoscopy - No Barrett's Esophagus

OTHER

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.

Device: Sponge Capsule

Interventions

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

Also known as: EsophaCap, Cytosponge
Screening PopulationUpper endoscopy - Barrett's EsophagusUpper endoscopy - No Barrett's Esophagus
