This is a multi-center, double-blind, parallel-group, randomized, proof of concept trial to investigate the relationship between dose of esomeprazole magnesium and acid-associated heartburn symptoms during 4 weeks of treatment. The safety and tolerability of esomeprazole magnesium in doses up to 40 mg BID will also be assessed.

Further study details as provided by AstraZeneca:

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