Capsule-sponge surveillance for ultralong-segment Barrett's esophagus

Ultralong-segment Barrett's Esophagus: Towards a Capsule-sponge Surveillance Strategy

Not applicable Interventional Erasmus Medical Center · NCT06720636

This tests whether the EndoSign capsule-sponge can detect precancerous changes and early esophageal cancer in adults with ultralong-segment Barrett's esophagus compared with standard endoscopy.

What this trial studies

Adults with ultralong-segment Barrett's esophagus will undergo both the EndoSign capsule-sponge test and a standard esophagogastroduodenoscopy (EGD) by an expert endoscopist, and the results will be compared for concordance in detecting dysplasia or esophageal adenocarcinoma. Cells collected by the capsule-sponge will be examined for cellular atypia and stained with p53 immunohistochemistry alongside testing of novel molecular biomarkers. The primary analysis will compare detection rates between the two methods to determine how well the nonendoscopic test matches endoscopic biopsy findings. If concordance is high, the capsule-sponge could offer a less invasive surveillance option for selected patients.

Who should consider this trial

Good fit: Adults aged 18 years or older with ultralong-segment Barrett's esophagus who are clinically fit for endoscopy and able to give informed consent are ideal candidates.

Not a fit: Patients with known advanced esophageal tumors, dysphagia, esophageal strictures or varices, recent swallowing-impairing cerebrovascular events, prior ablative treatments for dysplasia, or inability to swallow/consent are unlikely to benefit or be eligible.

Why it matters

Potential benefit: If successful, the EndoSign capsule-sponge could provide a less invasive, more acceptable way to monitor Barrett's esophagus and reduce the need for repeated endoscopies.

How similar studies have performed: Similar capsule-sponge approaches like the Cytosponge have shown promising results for detecting Barrett's-related changes, but the EndoSign device and its specific biomarker panel are newer and less widely tested.
