Trial Outcomes & Findings for Rabeprazole Extended-Release, 50 mg, Versus Esomeprazole, 40 mg, for Healing and Symptomatic Relief of Moderate to Severe Erosive Gastroesophageal Reflux Disease (GERD) (NCT NCT00658775)

NCT ID: NCT00658775

Last Updated: 2015-12-21

Results Overview

Healing at week 4 or 8 were based on improvement of eGERD of the Los Angeles (LA) classification of esophagitis Grade C or D from Baseline. Classifications include: Not Present: No breaks (erosions) in the esophageal mucosa (however, edema, erythema, or friability may be present) Grade A: One or more mucosal breaks not more than 5mm in maximum length. Grade B: One or more mucosal breaks more than 5mm in maximum length, but not continuous between the tops of 2 mucosal folds. Grade C: Mucosal breaks continuous between the tops of 2 or more mucosal folds, but involving less than 75% of the esophageal circumference. Grade D: Mucosal breaks involving at least 75% of the esophageal circumference.

SECONDARY outcome

Timeframe: Week 4

Population: ITT Population

During the first 4 weeks of the Double-blind Phase, participants were to record heartburn in a daily diary. Participant daily symptoms for the assessment of heartburn was based on a commonly used 4-point Likert scale of none, mild, moderate and severe. A participant was considered achieving sustained resolution of heartburn if the participant had maintained at least 7 consecutive heartburn-free days.
