  • 3. Active GERD as defined by a positive 24-hour pHmetry test at baseline. Positive is defined as having an esophageal pH of < 4 for > 5 % of the time.
  • 4. Body Mass Index (BMI) of approximately 18 to 32 kg/m2; and a total body weight within the range of 40 to 120 kg.
  • 5. Evidence of a personally signed and dated informed consent document indicating that the subject (or a legally acceptable representative) has been informed of all pertinent aspects of the trial.
  • 6. Subjects who are willing and able to comply with scheduled visits, treatment plan, laboratory tests, and other trial procedures.
  • Are the trial subjects under 18? no
  • Number of subjects for this age range:
  • F.1.2 Adults (18-64 years) yes
  • F.1.2.1 Number of subjects for this age range
  • F.1.3 Elderly (>=65 years) yes

  • 3. Subjects with a significant history of symptomatic postural hypotension or greater than a 20 mmHg drop in systolic or 10 mmHg drop in diastolic blood pressure on standing at screening.
  • 4. Subjects with previously diagnosed renal impairment. Subjects with creatinine values > 2x ULN and/or with a significant change to their normal values should be excluded.
  • 5. Subjects with previously diagnosed hepatic impairment. Subjects with liver function tests > 2 x ULN and/or with a significant change to their normal values should be excluded.
  • 6. Subjects with a history of esophageal strictures.
  • 7. Subjects with a history of esophageal dysmotility syndromes such as achalasia or nutcracker esophagus.
  • 8. Subjects with upper GI endoscopic scoring of Los Angeles grade D.
  • 9. Subjects with symptoms of dysphagia.
  • 10. Subjects currently being treated for active gastric or duodenal ulceration.
  • 11. Subjects diagnosed with Barrett’s esophagus.
  • 12. Subjects that have had a surgical treatment for GERD, e.g. fundoplication.
  • 13. Subjects with any condition possibly affecting drug absorption (e.g. gastrectomy).
  • 14. Subjects with a history or presence of esophageal or gastric neoplasms.
  • 15. Subjects with a history of allergic disease (including drug allergies, but not untreated or treated seasonal allergies or mild asthma/eczema).
  • 16. Subjects with a positive urine drug screen.

  • 18. Subjects who have received treatment with an investigational drug within 4 months preceding the first dose of study medication.
  • 19. Subjects who are unable or unwilling to withdraw from acid suppressing (e.g. proton pump inhibitors or H2 receptor antagonists), gastro-prokinetic or other drugs for the treatment of GERD for the duration of the study (including the 7 days prior to the baseline pHmetry test).
  • 20. Subjects who are taking or have taken within 14 days of dosing any drugs that are known to be potent CYP3A4 inhibitors (e.g. ketoconazole, erythromycin, clarythromycin).
  • 21. Subjects taking b-blocker agents within 28 days of first dose.
  • 22. Subjects with a screening 12-lead ECG demonstrating any of the following: heart rate >120 bpm, QRS duration >120 msec, QTc interval >430 msec, PR interval >210 msec, any clinically significant rhythm abnormality, any evidence of myocardial ischemia or injury.
  • 23. Subjects that have made a blood donation of approximately 1 pint (500 mL) within 56 days prior to dosing.
  • 24. Subjects with a history of sensitivity to heparin or heparin-induced thrombocytopenia.
  • 25. Subjects with any clinically significant laboratory abnormalities that may increase the risk associated with trial participation or may interfere with the interpretation of the trial results.
