The purpose of this study is to understand how quickly lansoprazole, once daily (QD), improves feeding in premature babies or babies less than 28 days of age.

Condition Intervention Phase
Gastroesophageal Reflux Disease Drug: Lansoprazole Phase 1

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment

Further study details as provided by Takeda:

Primary Outcome Measures:
  • Pharmacokinetic Analysis. [ Time Frame: Day 1 and 5 ]
  • Mean Intragastric 24 hour pH (subset of 6 subjects) [ Time Frame: Day -1, 1 and 5 ]

Secondary Outcome Measures:
  • Gastroesophageal Reflux Disease Symptom Assessment. [ Time Frame: Days 1-5 ]

Enrollment: 24
Study Start Date: January 2005
Study Completion Date: July 2005
Primary Completion Date: July 2005 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Lansoprazole 1.0 mg/kg QD Drug: Lansoprazole
Lansoprazole 1.0 mg/kg/day suspension, orally, once daily for up to 5 days.
Experimental: Lansoprazole 2.0 mg/kg QD Drug: Lansoprazole
Lansoprazole 2.0 mg/kg/day suspension, orally, once daily for up to 5 days.

Detailed Description:
A Phase 1, multicenter, pharmacokinetic/Pharmacodynamic and safety study in which infants will be randomized in an open-label fashion to receive 5 days of open-label treatment with lansoprazole pediatric suspension 1 mg/kg/day oral, or lansoprazole pediatric suspension 2 mg/kg/day oral. On Dosing Days 1 and 5, blood samples will be obtained for drug assay. All subjects will be evaluated for inclusion in the pH monitoring portion of the study and will undergo pH monitoring, provided it is clinically indicated, at the discretion of the investigator. Intragastric pH monitoring (up to 24 hours) will be performed at Baseline, on Dosing Day 1 (or Day 2) and on Dosing Day 5 (or Day 6). Intraesophageal pH may be done in addition to intragastric pH at the discretion of the investigator. Subjects will be evaluated for safety, including a follow-up visit on Post-Dosing Day 14.

Ages Eligible for Study:   up to 364 Days   (Child)

  • Clinically-evident Gastroesophageal Reflux Disease (feeding intolerance, regurgitation, wheezing or stridor with feedings)
  • At least 7 days post-surgery without anticipated need for surgery during study
  • No significant laboratory abnormalities

Exclusion Criteria:
