- Number of Participants With a Change in GERD Symptoms Corresponding to at Least Three More Days of Not More Than Mild Symptoms on Average Per Week During Treatment (Approximately 4 Weeks) Than During Baseline (the 7 Days Before Randomisation) [ Time Frame: The 7 days before randomisation (baseline) and during 26-30 days of treatment ]
Symptom intensity rated by participants twice daily on a six-graded Likert scale (Did not have; Very mild; Mild; Moderate; Moderately severe; Severe) using an electronic Reflux Symptom Questionnaire diary.
(GERD = Gastroesophageal Reflux Disease)
- Absolute Change From Baseline to Treatment Period in Percent Days With at Most Mild GERD Symptoms. [ Time Frame: The 7 days before randomisation (baseline) and during 26-30 days of treatment ]
Symptom intensity rated by participants twice daily on a six-graded Likert scale (Did not have; Very mild; Mild; Moderate; Moderately severe; Severe) using an electronic Reflux Symptom Questionnaire diary
