结局指标

主要结局

Percent Change From Baseline to Week 8 in Weekly Heartburn Severity Score (WHSS)

时间窗: 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.

  • Change From Baseline to Week 4 in WHSS(Baseline (derived from the eDiary daily data collected from 7 days before randomization up to the time of randomization), Week 4)

  • Percentage of Participants With a DHSS of No More Than Very Mild (≤ 1) on Any Day During Week 4(Week 4)

  • Change From Baseline in the Number of Days Where DHSS Was No More Than Very Mild (≤ 1) During Week 4(Week 4)
  • Change From Baseline Over Time in the Weekly Average of Modified Reflux Symptom Questionnaire - Electronic Diary (mRESQ-eD) Item 'Heartburn Severity'(Baseline (derived from the eDiary daily data collected from 7 days before randomization up to the time of randomization), Weeks 1, 2, 3, 4, 5, 6, 7, 8)
  • Change From Baseline Over Time in the Weekly Average of mRESQ-eD Item 'Burning Feeling Behind Breastbone or Center of Upper Stomach Severity'(Baseline (derived from the eDiary daily data collected from 7 days before randomization up to the time of randomization), Weeks 1, 2, 3, 4, 5, 6, 7, 8)
  • Change From Baseline Over Time in the mRESQ-eD Item 'Pain Behind Breastbone or Center of Upper Stomach Severity'(Baseline (derived from the eDiary daily data collected from 7 days before randomization up to the time of randomization), Weeks 1, 2, 3, 4, 5, 6, 7, 8)
