4. Alarm symptoms such as odynophagia, severe dysphagia, upper GI bleeding, weight loss, anemia, or hematochezia within 4 weeks prior to Screening, unless the presumed malignancy is ruled out;

5. History or suspicion of functional upper gastrointestinal disorders, such as:

• Functional heartburn, as described in the Rome IV criteria, or

• Functional dyspepsia, as described in the Rome IV criteria.

6. History of a connective tissue disorder associated with GI symptoms (eg, scleroderma or systemic lupus erythematous) or inflammatory bowel disease, or documented history of delayed gastric emptying;

7. History of acid-suppressive, esophageal, or gastric surgery;

o Note: This is not applicable to appendectomy, cholecystectomy, or endoscopic excision of benign tumor.

8. History of malignancy within the past 5 years (with the exception of resected basal cell or squamous cell carcinoma of the skin);

o Note: This is not applicable to patients who had complete response or pathological complete response and whose tumor had not recurred for at least 5 years from the date of last treatment, or patients whose tumor had been removed by endoscopic resection without any findings indicating recurrence of the tumor within 3 years.

9. History of an allergic disease, or hypersensitivity or intolerance to the active ingredient or excipients of the study drug;

10. History of alcoholism, chronic opiate use, or substance addiction in the 12 months before Screening or a positive urine drug screen for opiates or substances of abuse;

o Note: Patients on prescribed opioids are eligible to participate if they have been on a stable dose for >3 months prior to Screening.

11. Presence of manic-depression, anxiety disorder, panic disorder, somatoform disorder, personality disorder, or other psychological disorder;

12. Current use of antipsychotics, antidepressants, anxiolytics, or prescription sleeping medications, with the exception of a stable dose for >6 months prior to Screening;

13. Use of any gastric acid-suppressive agents, including PPIs, within 2 weeks prior to the upper GI endoscopy at Screening;

14. Use of 2 or more commercial doses of reflux esophagitis-related medications (including H2 blockers, prostaglandins, mucosal protective agents, prokinetics, and antacids) within 1 week prior to the upper GI endoscopy at Screening;

15. Requirement of persistent use of non-steroidal anti-inflammatory drugs (NSAIDs) during the course of the study;

o Note: Low-dose (≤100 mg/day) aspirin is allowed provided that it has been used for prophylaxis prior to study participation.

16. If a female, is pregnant, breastfeeding, or planning to become pregnant during the study or within 30 days after the last dose of study drug;

17. Positive test result for human immunodeficiency virus, hepatitis B surface antigen, or hepatitis C virus at Screening;

18. Abnormal laboratory results with clinical relevance at Screening as follows:

• Aspartate aminotransferase (AST), alanine aminotransferase (ALT), or alkaline phosphatase level of ≥2 × upper limit of normal (ULN);

• Total bilirubin level of ≥2 × ULN, unless Gilbert's syndrome is confirmed when direct bilirubin is ≤0.3 mg/dL;

• Estimated glomerular filtration rate <30 mL/min; or

• Serum magnesium19. Abnormal ECG of clinical significance (eg, major arrhythmia, multifocal premature ventricular contractions, or 2° atrioventricular block anomaly);

20. Presence of any gastric acid hypersecretory conditions, such as Zollinger-Ellison syndrome;

21. Involvement in another clinical study within 4 weeks of initiation of study drug; or
