Brief Summary:
The purpose of this study is to compare the efficacy of oral and rectal omeprazole treatment in infants with gastroesophageal reflux due to esophageal atresia or congenital diaphragmatic hernia.

Condition or disease Intervention/treatment Phase
Gastroesophageal Reflux Esophageal Atresia Hernia, Diaphragmatic Drug: Omeprazole rectally 1mg/kg Phase 3

Detailed Description:

Omeprazole is a highly effective drug for the treatment of gastroesophageal reflux disease (GERD) in infants. Infants, aged 0-12 months, require a non-standard dose of omeprazole. Due to this fact extemporaneous formulations of omeprazole are administered to these infants. The oral bioavailability of omeprazole in nonproprietary formulations may be unpredictable and produce variable degrees of drug exposure. The dose range for GERD management in pediatric studies using omeprazole is 0.3 - 3.5 mg/kg/day.

Dosing information, aged-specific pharmacodynamic and pharmacokinetic data are not available in infants, aged 0-12 months. Two adult studies at healthy volunteers suggest that an omeprazole suppository is an effective dosage form.This study is designed to evaluate and to compare the efficacy, the pharmacodynamics and the pharmacokinetics of oral and rectal omeprazole treatment in infants with gastroesophageal reflux disease.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 17 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Intervention Model Description: This study was an open-label randomized intervention trial to study the efficacy of a single oral or rectal administered omeprazole dose of 1 mg/kg in infants with GERD due to EA or CDH.
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Rectal and Oral Omeprazole Treatment of Gastroesophageal Reflux in Infants With Esophageal Atresia or Congenital Diaphragmatic Hernia; A Pharmacodynamic and Pharmacokinetic Study.
Actual Study Start Date : September 2005
Actual Primary Completion Date : September 2016
Actual Study Completion Date : September 2017

Arm Intervention/treatment
No Intervention: Oral omeprazole
Standard of care: A single dose of 1 mg/kg orally administered omeprazole.
Active Comparator: Rectal omeprazole
A single dose of 1 mg/kg rectally administered omeprazole.
Drug: Omeprazole rectally 1mg/kg
A single dose of 1 mg/kg rectally administered omeprazole.

Primary Outcome Measures :
  1. Therapeutic efficacy [ Time Frame: 24 hour ]
    Primary: percentage of infants for which omeprazole was effective according to predefined criteria for 24 hour intraesophageal pH.

Secondary Outcome Measures :
  1. Intragastric pH [ Time Frame: 24 hours ]
    Secondary: outcomes were the percentage of time gastric pH was <3 and <4

  2. Maximum plasma concentration (Cmax) [ Time Frame: 8 hours ]
    The maximal concentration of OME, OH-OME and OME-S in plasma (Cmax)

  3. Time to reach Cmax (Tmax) [ Time Frame: 8 hours ]
    time to reach Cmax (Tmax)

  4. Area under the curve (AUC) [ Time Frame: 8 hours ]
    The AUC from time zero to the last sampling time point (AUC0-t)
