Primary Outcome Measures:
  • The crude healing rate of EE at Week 8 of treatment as assessed by endoscopy [ Time Frame: 8 Weeks ]
    Endoscopic healing of erosive esophagitis is defined as those participants who have endoscopically confirmed EE of Grade O as defined by the Los Angeles (LA) Classification Grading System. The definitions of each grade are: Grade O (No mucosal break), Grade A (Mucosal break <5 mm), Grade B (Mucosal break ≥5 mm), Grade C (Mucosal break continuous between two or more folds and <75% of the circumference) and Grade D (Mucosal break ≥75% of the circumference).


Secondary Outcome Measures:
  • The crude healing rate of EE at Week 8 of treatment as assessed by endoscopy [ Time Frame: 4 Weeks ]
