Completed

Conditions studied: Coronary Artery Disease, Peripheral Artery Disease

In brief

• Have symptoms of dyspepsia or gastroesophageal reflux disease
• Have active internal bleeding or history of bleeding diathesis
• Have clinical findings, in the judgment of the investigator, associated with an increased risk of bleeding
• Have an International Normalized Ratio (INR) known to be >1.5 at the time of evaluation
• Have a platelet count of <100,000/mm3 at the time of screening, if known
• Have anemia (hemoglobin [Hgb] <10 gm/dL) at the time of screening, if known
• Are receiving or will receive oral anticoagulation or other antiplatelet therapy (other than aspirin) that cannot be safely discontinued for the duration of the study
