Safety and Efficacy of Ilaprazole 5, 20 and 40 mg QD and Lansoprazole 30 mg QD on Healing of Erosive Esophagitis

January 31, 2012 updated by: Takeda

A Phase 2 Study to Evaluate the Safety and Efficacy of Ilaprazole (5 mg QD, 20 mg QD and 40 mg QD) and an Active Comparator, Lansoprazole (30 mg QD) on Healing of Erosive Esophagitis.

The purpose of this study is to assess the efficacy and safety of 8 weeks of daily treatment with Ilaprazole (5, 20 and 40 mg), once daily (QD), compared to lansoprazole 30 mg in healing subjects with endoscopically proven erosive esophagitis.

Study Overview

Detailed Description

This 8 week study will be conducted by approximately 160 investigators in the United States. During this study, esophagitis healing will be evaluated by endoscopy, heartburn and other symptom relief will be evaluated by questionnaire and study drug levels will be measured.
