Inclusion criteria

  • Confirmed symptom history of heartburn, acid regurgitation, or epigastric pain of at least 3 months, while treating with gastric acid modulating therapy (antacids, H2 receptor antagonists (H2RAs) and/or PPIs).
  • Heartburn symptoms that average 3 times per week or greater including at least 2 episodes of nighttime heartburn symptoms per week over the past 30 days.
  • When heartburn medications were used, subject had heartburn symptoms that were responsive to antacids, non prescription H2RAs, or short term non prescription or prescription PPIs at approved doses but complete resolution of heartburn was not achieved.

Exclusion criteria

Exclusion Criteria:

  • A history (past or present) of erosive esophagitis verified by endoscopy.
  • The need for continuous treatment with H2RAs, PPIs, gastric prokinetic drugs, or antacids for any indication through the study (eg, long term prescription therapy).
  • Subjects requiring continuous intervention by a physician for the treatment of GERD (ie, treatment of erosive esophagitis or prevention of relapse of healed esophagitis).

What researchers measure

Primary outcomes

  1. Number of Participants With Relief of 24 Hour Heartburn and Without Relief of 24 Hour Heartburn

    Relief of 24 hour heartburn was defined as a daily diary response of "0" to the question "Over the last 24 hours (yesterday and last night), what was the severity of your most intense episode of heartburn?" on at least 6 of the participant's last 7 consecutive days \[Days 8 - 14\] of treatment allowing for one day with a maximum severity of "2".The response was noted by participants in the diary for last 7 consecutive days \[Day 8 - 14\] on a 3 point scale ranged from 0 to 2 where 0= complete relief and 2= maximum severity. Higher score indicated worse condition/more severity. In this outcome measure, participants with relief of 24 hour heartburn and participants without relief of 24 hour heartburn were reported.

    Time frame: Day 8 up to Day 14

  2. Change From Baseline at Day 14 in Percentage of Time Over 24--Hour Period With Intra Gastric pH Greater Than (>)4

    Percentage of time was calculated over the 24 hour period during which intra gastric pH \>4 was observed. Relief of 24 hour heartburn was defined as a daily diary response of "0" to the question "Over the last 24 hours (yesterday and last night), what was the severity of your most intense episode of heartburn?" on at least 6 of the participant's last 7 consecutive days \[Days 8 - 14\] of treatment allowing for one day with a maximum severity of "2".The response was noted by participants in the diary for last 7 consecutive days \[Day 8 - 14\] on a 3 point scale ranged from 0 to 2 where 0= complete relief and 2= maximum severity. Higher score indicated worse condition/more severity. In this outcome, change from baseline at Day 14 in percentage of time over the 24 hour period during which intra gastric pH \>4 was observed, was reported.
