1.Primary Outcome
Title Percentage of Participants With Erosive Gastroesophageal Reflux Disease (eGERD) Who Achieved Endoscopically-confirmed Healing by 8 Weeks
Hide Description

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.

3.Secondary Outcome
Title Percentage of Participants Who Achieved Diary-recorded Sustained Resolution of Heartburn by Week 4
Hide Description 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.
