Brief Summary:
This pilot clinical trial studies non-endoscopic brushing of the esophagus using a non-endoscopic inflatable balloon for the esophagus in screening for Barrett esophagus, a condition where the lining of the esophagus has changed or been replaced with abnormal cells that may lead to cancer. The non-endoscopic inflatable balloon for the esophagus is a capsule balloon that brushes against the walls of the esophagus to collect esophageal samples. Non-endoscopic brushing of the esophagus using a non-endoscopic inflatable balloon for the esophagus may help doctors find Barrett esophagus sooner, when it may be easier to treat.

Condition or disease Intervention/treatment Phase
Barrett Esophagus Device: non-endoscopic inflatable balloon for the esophagus Other: Questionnaire Administration Other: Laboratory Biomarker Analysis Procedure: esophagogastroduodenoscopy Not Applicable

Detailed Description:

PRIMARY OBJECTIVES:

I. To determine acceptability of non-endoscopic balloon brushing of esophagus.

II. To demonstrate successful performance of the methylation of vimentin (mVIM) assay in balloon brushings from subjects with and without Barrett's Esophagus (BE).

III. To examine molecular and histological factors that might lead to false negative and false positive mVIM assays in BE screening.

IV. To assay additional methylated deoxyribonucleic acid (DNA) biomarkers that might improve the sensitivity and specificity of mVIM in balloon brushings.

OUTLINE:

Patients undergo non-endoscopic brushing of the esophagus using a non-endoscopic inflatable balloon for the esophagus over 30-60 minutes followed by a standard esophagogastroduodenoscopy (EGD).

After completion of study, patients with serious adverse events are followed up until resolution, stabilization, or until it has been determined that the study treatment or participation is not the cause.

Arm Intervention/treatment
Experimental: Screening: non-endoscopic inflatable balloon for the esophagus
Patients undergo non-endoscopic brushing of the esophagus using a non-endoscopic inflatable balloon for the esophagus over 30-60 minutes followed by a standard esophagogastroduodenoscopy. Questionnaire administration will provide self-reported data on patient experiences. laboratory biomarker analysis of biopsy will confirm diagnosis.

Primary Outcome Measures :
  1. Number of Participants Reporting Each Category of Tolerance Assessed by the Tolerance Survey [ Time Frame: At completion of study procedure (up to 60 minutes) ]
    Mean tolerance score as assessed by 'tolerance survey' with scores ranging from 0 to 50 with higher scores indicating worse tolerance of interventional balloon device. Subscales include anxiety, pain, choking, gagging, and overall tolerance, with each domain scores ranging from 0 to 10, with higher scores indicating worse tolerance of interventional balloon device.

  2. Sensitivity of the mVIM Assay in Balloon Brushings From Participants With BE [ Time Frame: Up to 1 year ]
    Sensitivity of the mVIM assay in balloon brushings from participants with BE as measured by true positives determined by biomarker (mVIM and mCCNA1) analyses of corresponding esophageal balloon derived samples compared to initial diagnosis. The presence of at least 1% of methylated VIM in DNA extracted from the esophageal sampling balloon will be considered a positive assay.

  3. Specificity of the mVIM Assay in Balloon Brushings From Control Participants With no BE Diagnosis [ Time Frame: Up to 1 year ]
    Specificity of the mVIM assay in balloon brushings from control subjects with BE as measured by true negatives determined by biomarker (mVIM and mCCNA1) analyses of corresponding esophageal balloon derived samples compared to initial control status. The presence of at least 1% of methylated VIM in DNA extracted from the esophageal sampling balloon will be considered a positive assay.

  4. Average Methylation of Methylated Beta-1,3-glucuronyltransferase 2 Assays [ Time Frame: Up to 7 months ]
    Average methylation of methylated beta-1,3-glucuronyltransferase 2 assays

  5. Performance of the mVIM Assay in Balloon Brushings From Subjects Without BE [ Time Frame: Up to 7 months ]
    Performance of the mVIM assay in balloon brushings from subjects without BE

  6. Average Methylation of Zinc Finger Protein 793 Assay [ Time Frame: Up to 7 months ]
    Average methylation of zinc finger protein 793 assay
