Design outcomes

Primary

MeasureTime frameDescription
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.8 weeksLos 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).

Outcome results

Primary

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.

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).

Time frame: 8 weeks

Population: One participant for each treatment group did not take any investigational product. These 3 participants were excluded (1 for each treatment group) from all the efficacy and safety analyses.
