Clinical Trial Summary

This study compares mechanical sphincter augmentation (LINX Reflux Management System) to double-dose proton pump inhibitors (PPIs) for the management of reflux symptoms related to gastroesophageal reflux disease (GERD).


Description:

Prospective, multicenter, 2:1 randomized, cross-over, two arms

- Control arm: Double-dose PPI [Omeprazole 20 mg BID (twice a day)]

- Treatment arm: LINX Reflux Management System Up to 20 study centers throughout the U.S. will participate. Approximately150 patients will be enrolled into the study. Subjects will be randomized 2:1 into the double-dose PPIs arm (100 subjects) and the LINX arm (50 subjects).

Outcome

Type Measure Description Time frame Safety issue
Primary Elimination of Moderate-severe Regurgitation at 6 Months The primary endpoint was the percent of patients in both treatment arms who achieved elimination of moderate-severe regurgitation at 6 months, as reported on the foregut symptom questionnaire. 6 months
Secondary Percentage of Subjects With =50% Reduction in Total Gastroesophageal Reflux Disease-Health Related Quality of Life (GERD-HRQL) Scores Successful Reduction at 6 months (=50% reduction in total) Gastroesophageal Reflux Disease-Health Related Quality of Life (GERD-HRQL) scores from Baseline PPI On medication GERD HRQL scores. 6 months
