Trial Outcomes & Findings for Study Evaluating the Efficacy and Safety of Pantoprazole in Infants With Symptomatic Gastroesophageal Reflux Disease (GERD) (NCT NCT00365300)

NCT ID: NCT00365300

Last Updated: 2010-05-04

Results Overview

Lack of efficacy defined as 1 or more of the following occurring during the double blind treatment-withdrawal phase: significant worsening of gastroesophageal reflux disease (GERD) symptoms frequency, a diagnostic test (e.g., endoscopy) demonstrating worsening of esophagitis, maximal antacid intake for ≥ 7 continuous days, or severe GERD symptoms based on physician's judgment.

Pantoprazole Sodium Granules
Double Blind Treatment-withdrawal phase (weeks 5-8) Pantoprazole sodium granules at a dose of approximately 1.2 mg/kg daily (5 mg for weight \< 7 kg or 10 mg for weight ≥ 7 kg) in an oral suspension. An Open Label Treatment run-in phase (weeks 1-4) preceded the Double Blind Treatment-withdrawal phase and patients received: Pantoprazole sodium granules at a dose of approximately 1.2 mg/kg daily (5 mg for weight \< 7 kg or 10 mg for weight ≥7 kg) in an oral suspension.
Placebo
Double Blind Treatment-withdrawal phase (weeks 5-8): Matching placebo. An Open Label Treatment run-in phase (weeks 1-4) preceded the Double Blind Treatment-withdrawal phase and patients received Pantoprazole sodium granules at a dose of approximately 1.2 mg/kg daily (5 mg for weight \< 7 kg or 10 mg for weight ≥7 kg) in an oral suspension.

PRIMARY outcome

Timeframe: 4 weeks double-blind

Population: The analysis population was the Modified Intent to Treat, which included all GERD patients who completed the 4 week open-label treatment phase, were randomized into the 4 week double-blind phase, and took at least one dose of double-blind treatment.

Lack of efficacy defined as 1 or more of the following occurring during the double blind treatment-withdrawal phase: significant worsening of gastroesophageal reflux disease (GERD) symptoms frequency, a diagnostic test (e.g., endoscopy) demonstrating worsening of esophagitis, maximal antacid intake for ≥ 7 continuous days, or severe GERD symptoms based on physician's judgment.
