Primary Outcome Measures:
  • Percentage of Days With Neither Daytime Nor Nighttime Heartburn During Treatment as Assessed by Daily Electronic Diary-Median [ Time Frame: 4 weeks ]
    The percentage was calculated as the days that were heartburn-free out of the total number of days for which either a daytime or nighttime result was marked.

  • Percentage of Days With Neither Daytime Nor Nighttime Heartburn During Treatment as Assessed by Daily Electronic Diary-Mean [ Time Frame: 4 weeks ]
    The percentage was calculated as the days that were heartburn-free out of the total number of days for which either a daytime or nighttime result was marked.

Secondary Outcome Measures:
  • Percentage of Days Without Nighttime Heartburn During Treatment as Assessed by Daily Electronic Diary-Median [ Time Frame: 4 weeks ]
    The percentage was calculated as the nights that were heartburn-free out of the total number of days for which a nighttime result was marked.

  • Percentage of Days Without Nighttime Heartburn During Treatment as Assessed by Daily Electronic Diary-Mean [ Time Frame: 4 weeks ]
    The percentage was calculated as the nights that were heartburn-free out of the total number of days for which a nighttime result was marked.

Detailed Description:
This is a Phase 3, randomized, double-blind, multicenter, placebo-controlled, 3-arm study with a 4 week treatment period. This study will compare the efficacy of Dexlansoprazole MR (30 mg QD and 60 mg QD) with that of placebo when administered orally as a single daily dose in the morning, before breakfast. The study is designed to evaluate symptom relief in subjects with symptomatic nonerosive GERD. Approximately 900 subjects will be enrolled at approximately 200 United States (US) and potentially ex-US sites. The study consists of two periods: a screening period, which will last a minimum of 7 days and a maximum of 21 days, and a treatment period, which will last 4 weeks.

Ages Eligible for Study:   18 Years and older   (Adult, Senior)

Accepts Healthy Volunteers:   No

Inclusion Criteria:
