Primary Outcome Measures :
  1. Sustained resolution of heartburn during the 4th week of treatment, defined as 7 consecutive days with a daily e-diary heartburn assessment of "None".

Secondary Outcome Measures :
  1. Relief of heartburn during the 4th week of treatment
  2. Cumulative daily sustained resolution rate through 4 weeks of treatment
  3. Time to first day of the first 7-day period of sustained resolution of heartburn
  4. Time to the first day of the first 7-day period of relief of heartburn
  5. Percentage of subject-reported heartburn-free days through 4 weeks of treatment
  6. Percentage of subject-reported heartburn-free nights through the 4 weeks of treatment
  7. Safety and tolerability: adverse events, clinical laboratory tests, vital signs, physical examination.
