Reflux Esophagitis Phase III Study (Maintenance Treatment)

May 18, 2010 updated by: AstraZeneca

A Multicentre, Randomised, Double-blind, Parallel-group, Comparative Study to Compare the Efficacy and Safety of Esomeprazole 20 mg Once Daily Oral Administration With Omeprazole 10 mg and Esomeprazole 10 mg Once Daily Oral Administration in Maintenance Treatment in Patients With Healed Reflux Esophagitis

The primary objective of this study is to evaluate the efficacy of esomeprazole 20 mg once daily for 24 weeks on maintenance of Reflux Esophagitis in patients with healed reflux esophagitis in comparison with omeprazole 10 mg once daily and esomeprazole 10 mg once daily by assessment of presence/absence of recurrence of Reflux Esophagitis throughout the treatment period (from the randomisation to the treatment completion) according to the Los Angeles classification.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Absence of Recurrence of Reflux Esophagitis According to Los Angeles Classification Throughout the Treatment Period.
Time Frame: Up to 24 weeks
Los Angels classification consists of 5 grades (Grade O, Grade A, Grade B, Grade C and Grade D). A patient classfied into Grade O was considered no reflux esophagitis. The participants who had a healing of reflux esophagitis with Grade O at Visit 1 were randomised. Number of participants who did not have Grades A-D throughout the treatment period was evaluated.
Up to 24 weeks

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Absence of Recurrence of Reflux Esophagitis According to Los Angeles Classification up to 4 Weeks After Treatment
Time Frame: up to 4 weeks
Los Angels classification consists of 5 grades (Grade O, Grade A, Grade B, Grade C and Grade D). A patient classfied into Grade O was considered no reflux esophagitis. The participants who had a healing of reflux esophagitis with Grade O at Visit 1 were randomised. Number of participants who did not have Grades A-D up to 4 weeks after treatment was evaluated.
up to 4 weeks
Absence of Recurrence of Reflux Esophagitis According to Los Angeles Classification up to 12 Weeks After Treatment
Time Frame: Up to 12 weeks
Los Angels classification consists of 5 grades (Grade O, Grade A, Grade B, Grade C and Grade D). A patient classfied into Grade O was considered no reflux esophagitis.
