About this study
Official title: Minimally-Invasive Detection of Barrett's Esophagus and Barrett's Esophagus Related Dysplasia/Carcinoma by a Sponge on String Device
This study is being done to collect data on the potential use of a sponge on a string device as a non-invasive tool in evaluating patients with Barrett's Esophagus compared to healthy controls.
Read the detailed description
This study will be conducted in two phases: Phase 1 and Phase 2. Phase 1 will consist of determining the most optimal sponge on a string design (25 mm sponge 20 pores/inch or 25 mm sponge 10 pores/inch) chosen based on participant acceptance, tolerability, mucosal irritation and DNA yield, using a randomized factorial design pilot trial. Participants will first undergo the sponge on a string test followed by clinical endoscopy. Following completion of Phase 1 trial, the most optimal sponge on a string configuration will be chosen for Phase 2. Phase 2 will be conducted using a single size sponge with the same porosity configuration selected from Phase 1. Study procedures, testing and follow up will be the same as Phase 1.

What is being measured
The primary outcome is the main question the study is designed to answer.
Number of Subjects That Would Have This Procedure Again
Number of subjects that answered yes to the self-reported question "Would you choose to have this procedure again to screen for Barrett's esophagus?"
Measured: Within 24 hours of the capsule sponge administration
Tolerability of Swallowing the Sponge Device
Measured using a self-reported 5-item tolerability assessment rating discomfort during the procedure on a Likert scale of 0-10; 10 representing the "worst experience" and 0 the "best experience." This scale allows a comprehensive and individual assessment of the degree of pain, choking, gagging, anxiety and overall experienced during the procedure.
Measured: Within 24 hours of the capsule sponge administration
Mucosal Irritation
Measured using a mucosal injury score (ranging from 1=no trauma to 5=severe) was scored from video recordings of the subsequent endoscopy conducted
Measured: Within 24 hours of the capsule sponge administration
DNA Yield
Total amount of DNA obtained from esophageal cytology specimens collected by the capsule sponge devices.
Measured: Within 24 hours of the capsule sponge administration
Secondary outcomes (2)
Sensitivity of Barrett's Dysplasia Detection
The sensitivity methylated DNA markers detected by the capsule sponge, in making a diagnosis of BE related dysplasia will be assessed using endoscopic surveillance biopsy histology as a gold standard.
Measured: Within 24 hours of the capsule sponge administration
Specificity of Barrett's Dysplasia Detection
The specificity of methylated DNA markers detected by the capsule sponge, in identifying subjects without a diagnosis of BE related dysplasia will be assessed using endoscopic surveillance biopsy histology as a gold standard.
Measured: Within 24 hours of the capsule sponge administration

Questions about this trial
What is this clinical trial studying?
A study testing Biopsy, Biospecimen Collection and Endoscopic Procedure in people with Barrett Esophagus, run by Mayo Clinic at 6 sites in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 14 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 17 Nov 2022. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 6 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Yes. Results are posted in the registry (first posted 16 Sep 2022). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Number of Subjects That Would Have This Procedure Again (time frame: Within 24 hours of the capsule sponge administration). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02560623, which also lists 3 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Nov 2022.
