Barrett's Esophagus - 315 - 3 Way Cross-Over

January 24, 2011 updated by: AstraZeneca

A Multicenter, Double-blind, Three-way Crossover Intraesophageal and Intragastric pH Study of Three Esomeprazole Treatment Regimens in Documented Barrett's Esophagus Patients

This study looks the intragastric and intraesophageal pH in patients with documented Barrett's esophagus whilst taking esomeprazole 40mg twice daily, esomeprazole 40mg three times daily, esomeprazole 20 mg three times daily.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Time Frame

Time Frame: pH measured on Day 5
pH measured on Day 5

Secondary Outcome Measures

Outcome Measure
Time Frame
