Further study details as provided by Takeda:

Primary Outcome Measures:
  • Maximal Acid Output obtained 22 hours after the last dose of IV lansoprazole compared to the Maximal Acid Output obtained 22 hours after the last dose of oral lansoprazole following pentagastrin stimulation in both instances. [ Time Frame: Day 7 vs Day 15 ]

Secondary Outcome Measures:
  • Basal Acid Output obtained 21 hours after the last dose of IV lansoprazole compared with that obtained 21 hours after the last dose of oral lansoprazole. [ Time Frame: Day 7 vs Day 15 ]
  • Maximum Acid Output and Basal Acid Output measurements obtained 21 hours and 22 hours, respectively, after the first dose of IV lansoprazole versus those obtained after the last dose of oral lansoprazole. [ Time Frame: Day 7 vs Day 8 ]
  • Maximum Acid Output and Basal Acid Output results obtained after the first versus last dose of IV lansoprazole. [ Time Frame: Day 8 vs Day 15 ]

Enrollment: 68

Other Name: AG-1749

Detailed Description:
Phase 2, open label, multi-center, 2-period study to compare the pharmacodynamics of IV lansoprazole 30 mg to oral lansoprazole 30 mg in subjects with erosive esophagitis (grade >or= 2)diagnosed by endoscopy.

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Subjects were required to have Grade 2, 3 or 4 esophageal findings according to the TAP Grading Scale during the pretreatment endoscopy.
  • Subjects must discontinue histamine H2-receptor antagonists, proton pump ® inhibitors, prokinetic agents, antacids and Carafate before the first dose of drug and during the study.

Exclusion Criteria:

  • Gastric or duodenal ulcer (a lesion with appreciable depth ≥3 mm) or a hiatal hernia >5 cm.
  • Subjects could not have a diagnosis of Barrett's esophagus (with or without dysplastic changes).
  • Co-existing systemic disease affecting the esophagus, (ie, scleroderma, viral or fungal infection), radiation therapy to the region of the esophagus, or caustic or physiochemical trauma to the esophagus.
  • Current esophageal stricture requiring dilatation. The endoscope had to pass freely into the stomach during endoscopy. Any strictures could not have been dilated within 12 weeks before beginning the Pretreatment Period.
  • Positive H pylori by rapid urease test (CLO® test Kimberly-Clark Corporation).
  • Uncontrolled, clinically significant cardiovascular, pulmonary, renal, hepatic, metabolic, gastrointestinal, neurological or endocrine disease or other abnormality (other than the erosive esophagitis disease being studied).
  • Diagnosis of Zollinger-Ellison syndrome, esophageal varices, symptomatic pancreaticobiliary tract disease, cholecystitis, rheumatoid arthritis, lupus, or malignancy (except basal cell carcinoma).
