  Purpose
This study is to evaluate the efficacy of esomeprazole 20 mg once daily and 40 mg once daily for 8 weeks on healing of Reflux Esophagitis in patients with reflux esophagitis in comparison with omeprazole 20 mg once daily by assessment of presence/absence of Reflux Esophagitis at Week 8 according to the Los Angeles classification .

Condition Intervention Phase
Reflux Esophagitis Drug: Esomeprazole Drug: Omeprazole Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: A Multicentre, Randomised, Double-blind, Parallel-group, Comparative Study to Compare the Efficacy and Safety of Esomeprazole 20 mg and 40 mg Once Daily Oral Administration With Omeprazole 20 mg Once Daily Oral Administration in Patients With Reflux Esophagitis

Primary Outcome Measures:
  • Number of Participants With Healing of Reflux Esophagitis (RE) Who Were Graded "O" at Week 8 Out of Patients Who Were Graded "A, B, C or D" at Baseline According to Los Angeles Classification". [ Time Frame: 8 weeks ]
    Los Angeles classification consists of 5 grades (Grade O, Grade A, Grade B, Grade C, Grade D). The subjects who were definitely diagnosed to have RE classified into LA classification Grade A, B, C or D based on the EGD on Visit 1 were randomised. A subject classified into LA classification Grade O was considered no reflux esophagitis. The definitions of each grade are: Grade A (Mucosal break < 5 mm in length), Grade B (Mucosal break > 5mm), Grade C (Mucosal break continuous between > 2 mucosal folds) and Grade D (Mucosal break >75% of esophageal circumference).


Secondary Outcome Measures:
  • Number of Participants With Healing of Reflux Esophagitis (RE) Who Were Graded "O" at Week 4 Out of Patients Who Were Graded "A, B, C or D" at Baseline According to Los Angeles Classification [ Time Frame: 4 weeks ]
    Los Angeles classification consists of 5 grades (Grade O, Grade A, Grade B, Grade C and Grade D). The subjects who were definitely diagnosed to have RE classified into LA classification Grade A, B, C or D based on the EGD on Visit 1 were randomised. A subject classified into LA classification Grade O was considered no reflux esophagitis. The definitions of each grade are: Grade A (Mucosal break < 5 mm in length), Grade B (Mucosal break > 5mm), Grade C (Mucosal break continuous between > 2 mucosal folds) and Grade D (Mucosal break >75% of esophageal circumference).
