Study Endpoints

Primary Endpoints

Change From Baseline in WHSS at Week 8
Baseline, Week 8

The WHSS is defined as the weekly average of the DHSS. The DHSS for a day is the greater of the 2 items assessing heartburn severity (Item #1 "Burning feeling behind the breastbone or in the center of the upper stomach" and Item #2 "Pain behind the breastbone or in the center of the upper stomach"). The DHSS items are assessed on a 5-point ordinal scale, where 0=Did Not Have, 1=Very Mild, 2=Mild, 3=Moderate, 4=Moderately Severe, and 5=Severe; higher scores indicate worse symptoms. A negative change from baseline indicates improvement.

Percent Change From Baseline to Week 8 in Weekly Heartburn Severity Score (WHSS)
Baseline (derived from the eDiary daily data collected from 7 days before randomization up to the time of randomization), Week 8

The WHSS for an analysis week was defined as the average of available DHSS during that week. DHSS was defined as the maximum on a 6-point scale (0=Did Not Have, 1=Very Mild, 2=Mild, 3=Moderate, 4=Moderately Severe, 5=Severe) of the 3 items measuring heartburn ( "Heartburn," "Burning feeling behind breastbone or in the center of the upper stomach," and "Pain behind breastbone or in the center of the upper stomach,") from a particular day. A negative change from Baseline indicates improvement.
