The study which the subject is participating or participated in is a non-interventional study (e.g. observational study or questionnaire survey) and is judged by investigators to have no interference with the efficacy and safety evaluation in the present study;~  2.

History of malignant tumor within 5 years prior to screening (if the subject's basal cell carcinoma or cervical carcinoma in situ has been cured, he/she will be allowed to participate in this study).~12. Subject with history of upper GI surgery (except endoscopic surgery such as resection of benign polyp, etc.).~13. Subject who plans to be hospitalized for receiving selective surgery during the study.~14. Subject with uncontrolled and unstable hepatic, renal, cardiovascular, respiratory, endocrine, hematologic or central nervous system disease as judged by investigators.~15. Subject with history of chronic alcohol consumption \[more than 14 units per week, each unit corresponds to 360 mL beer (ABV ≈ 5%) or 45 mL spirit (ABV ≈ 40%) or 150 mL wine (ABV ≈ 12%)\] or drug abuse within 5 years prior to screening.~16. Subject whose upper gastrointestinal tract endoscopy shows GI bleeding (grade I, IIa or IIb per Forrest classification), esophageal stenosis, ulcerative stenosis, pyloric stenosis, gastroesophageal varices, Barrett's esophagus \>3 cm (i.e., long-segment Barrett's esophagus, LSBE), gastroesophageal reflux disease, acute gastroduodenal mucosal lesion (AGDML), active gastric ulcer, refractory ulcer, ulcer perforation or suspected malignant disease.~17. Subject who has other severe GI diseases such as Crohn's disease, ulcerative colitis, etc.~18. Use of any PPI, anticholinergic drug, gastrin receptor antagonist, H2 receptor antagonist, prostaglandin, mucosal protective agent, prokinetic, antacid or any other therapeutic drugs for peptic ulcer within 14 days prior to the first dose of study drug.~19. Subject who has thrombotic disease (e.g., cerebral thrombosis, myocardial infarction, thrombophlebitis, etc.) or is currently on anticoagulant therapy.~20. Subject who needs to use nonsteroidal anti-inflammatory drugs (NSAIDs) continuously during the course of the study.~21.
