Efficacy and Safety of Dexlansoprazole Modified Release Formulation to Treat Heartburn

April 25, 2011 updated by: Takeda

A Phase 3 Study to Evaluate the Efficacy and Safety of Dexlansoprazole MR (60 mg Once-Daily (QD) and 90 mg QD) Compared to Placebo on Symptom Relief in Subjects With Symptomatic Non-Erosive Gastroesophageal Reflux Disease (GERD)

The purpose of this study is to assess the efficacy and safety of daily treatment with Dexlansoprazole modified release (MR) (60 mg or 90 mg once daily [QD]) compared to placebo QD in relief of daytime and nighttime heartburn over 4 weeks in subjects with gastroesophageal reflux disease (GERD).

Detailed Description

This is a Phase 3, randomized, double-blind, multicenter, placebo-controlled, 3-arm study with a 4 week treatment period. This study will compare the efficacy of daily Dexlansoprazole MR (60 mg and 90 mg) with that of placebo when administered orally as a single daily dose in the morning, before breakfast. The study is designed to evaluate symptom relief in subjects with symptomatic non-erosive GERD. Approximately 450 subjects will be enrolled at approximately 120 U.S. and potentially ex U.S. sites. The study consists of two periods; a screening period, which will last a minimum of 7 days and a maximum of 21 days, and a treatment period, which will last 4 weeks.

Because the development plan for Dexlansoprazole MR was revised, the results of 2 identical studies, T-GD04-082 (this posting, NCT00241745) and T-GD04-083 (NCT00251758), were combined and analyzed as a single larger study referred to as study T-GD04-082. A total of 908 subjects were included in the combined analysis; 416 subjects were enrolled into Study T-GD04-082 and 492 subjects were enrolled into Study T-GD04-083.
