Using a swallowable sponge to collect esophageal samples for Barrett's esophagus detection

Official title: Assessment of a Minimally Invasive Collection Device for Molecular Analysis of Esophageal Samples for the Non-endoscopic Detection of Barrett's Esophagus With and Without Dysplasia

Run by Mayo Clinic · NCT06071845 · Data updated 2026-11-12

This study is testing a swallowable sponge to see if it can safely collect samples from the esophagus to help detect Barrett's esophagus and esophageal cancer in patients who may have these conditions.

Is this trial a fit for you?

Likely a good fit

Ideal candidates include adults aged 18-90 with known or suspected Barrett's esophagus or those undergoing clinically indicated endoscopy without a history of BE.

Probably not a fit

Patients who are pregnant, unable to consent, or have certain esophageal conditions or are on specific anticoagulant medications may not benefit from this study.

What this trial studies

This clinical trial evaluates the Cytosponge, a minimally invasive device, for collecting esophageal samples to detect Barrett's esophagus (BE) and esophageal adenocarcinoma (EAC). Patients will either have known or suspected BE or will be controls without a history of BE, and will undergo sample collection followed by standard endoscopy. The study aims to measure DNA yield from the samples and assess the accuracy of the Oncoguard Esophagus test in identifying biomarkers for BE/EAC. Additionally, the tolerability of the Cytosponge device will be evaluated through patient surveys.

Why it matters

Potential benefit: If successful, this approach could provide a simpler and more cost-effective method for early detection of Barrett's esophagus and esophageal adenocarcinoma.

How similar studies have gone: Other studies have shown promise with similar non-endoscopic approaches for Barrett's esophagus screening, indicating potential for success.
