Comparing two ways of taking acid-blocking medications for stomach ulcers after gastric bypass surgery

OPEN Versus InTact Capsule Proton Pump Inhibitors for the Treatment of Marginal Ulcers After Bariatric Surgery

Phase 4 Interventional The Cleveland Clinic · NCT05799105

This study is testing whether taking acid-blocking medication for stomach ulcers in an open capsule form works better than taking it in a whole capsule for people who have had gastric bypass surgery.

What this trial studies

This clinical trial aims to determine the effectiveness of taking proton pump inhibitors (PPIs) in two different forms: as an open capsule versus an intact capsule for treating marginal ulcers in patients who have undergone gastric bypass surgery. Participants diagnosed with marginal ulcers will be instructed to take either the contents of the capsule or the whole capsule, with their healing monitored through regular upper endoscopies. The study seeks to assess whether the open-capsule method leads to better healing outcomes and fewer complications compared to the traditional method. This is the first trial of its kind to explore this approach in this patient population.

Who should consider this trial

Good fit: Ideal candidates for this study are patients diagnosed with marginal ulcers following gastric bypass surgery.

Not a fit: Patients who are currently using open-capsule PPIs or refuse to start PPI medication will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a more effective treatment option for patients with marginal ulcers, potentially reducing complications and the need for additional procedures.

How similar studies have performed: This approach is novel and has not been previously tested in clinical trials for this specific patient population.
