Percentage of Participants Who Experienced the Occurence of Peptic Ulcer(s). [ Time Frame: During 26 weeks ]
The occurrence of ulcer (mucosal break measuring >= 3 mm over its largest diameter with a sharply demarcated margin) was determined by endoscopy performed at baseline, 8 weeks and 26 weeks or upon withdrawal.
The primary variable is time to occurrence of peptic ulcer(s).

  • Percentage of Participants Who Experienced the Occurence of Gastric Ulcer. [ Time Frame: During 26 weeks ]
    The occurrence of gastric ulcer (mucosal break measuring >= 3 mm over its largest diameter with a sharply demarcated margin) was determined by endoscopy performed at baseline, 8 weeks and 26 weeks or upon withdrawal.
  • Percentage of Participants Who Experienced the Occurrence of Duodenal Ulcer. [ Time Frame: During 26 weeks ]
    The occurrence of duodenal ulcer (mucosal break measuring >= 3 mm over its largest diameter with a sharply demarcated margin) was determined by endoscopy performed at baseline, 8 weeks and 26 weeks or upon withdrawal.
  • Number of Participants Reporting 0 in the Dichotomized RDQ (Reflux and Disease Questionnaire) Score (0 Versus >0) for the Dyspepsia Dimension During the 26-week Visit or the Week Prior to the Last Visit. [ Time Frame: RDQ was assessed at baseline, 8 weeks, 16 week, 26 weeks or upon withdrawal. ]
    RDQ contains 12 items on a 6-point Likert scale. Six items concern the frequence ('Did not have' to 'Daily') and six items concern the severity ('Did not have' to 'Severe'). The dyspepsia dimension contains the items 'Burning feeling in the center of the upper stomach' and 'Pain in the center of the upper stomach'. Best score possible 0, worst score possible - daily occurrence.
  • Number of Participants Reporting 0 in the Dichotomized RDQ (Reflux and Disease Questionnaire) Score (0 Versus >0) for the Gastroesophageal Reflux Disease Dimension During the 26-week Visit or the Week Prior to the Last Visit. [ Time Frame: RDQ was assessed at baseline, 8 weeks, 16 week, 26 weeks or upon withdrawal. ]
    RDQ contains 12 items on a 6-point Likert scale. Six items concern the frequency ('Did not have' to 'Daily') and six items concern the severity ('Did not have' to 'Severe'). Gastroesophageal reflux disease (GERD) items: 'Acid taste in the mouth', 'Unpleasant movement of materials upward from the stomach', 'Burning feeling behind the breastbone' and 'Pain behind the breastbone'. Best score possible 0, worst score possible - daily occurrence.
  • Number of Participants With Gastric and/or Duodenal Erosions. [ Time Frame: The number of erosions was determined by endoscopy performed at baseline, 8 weeks and 26 weeks or upon withdrawal. ]
  • Time to occurrence of gastric/duodenal ulcer.
  • Dichotomized RDQ score for the dyspepsia/GERD dimension
  • Number of gastric/duodenal erosions
  • Adverse events, lab and vital signs

Inclusion Criteria:

  • Daily intake of low-dose Aspirin (ASA) - The subject must fulfill at least one of the following (a-e):
  • Aged ≥65 years.
  • Aged ≥18 years and with a documented history of uncomplicated peptic ulcer(s).
  • Aged ≥60 years and naïve to low-dose ASA (ie, treatment started within 1 month prior to randomization).
