However, participants with Barrett's mucosa (less than 3 cm, short segment Barrett's esophagus \[SSBE\]) or Schatzki's ring (a mucosal tissue ring lining the inferior esophageal sphincter) are permitted to participate.~7. The participant has a history of surgery or treatment affecting gastroesophageal reflux, including fundoplication and mechanical dilatation for esophageal stenosis (except Schatzki's ring), or a history of gastric or duodenal surgery (except endoscopic removal of benign polyps).~8. The participant has acute upper gastrointestinal bleeding or gastric or duodenal ulcer, characterized by a defective mucosa with white coating, within 30 days prior to the start of the run-in period (Visit 1).

The participant has any other concurrent upper gastrointestinal symptoms more severe than heartburn.~13. The participant has depression.~14. The participant has, has a history of, or is suspected of functional upper gastrointestinal disorders, such as functional dyspepsia and functional heartburn diagnosed by the Rome IV criteria.~15. The participant has a history of hypersensitivity or allergies to TAK-438 (including the formulation excipients).~16. The participant has a history or complication of drug abuse (defined as any illicit drug use) or of alcohol abuse within 1 years prior to the start of the run-in period (Visit 1).~17.

The participant needs surgery requiring hospitalization during the course of the study, or surgery requiring hospitalization is scheduled for the participant during the course of the study.~21. The participant has a history of malignancy or is treated for malignancy within 5 years prior to the start of the run-in period (Visit 1). However, participants who have recovered completely from cutaneous basal cell carcinoma or from cervical carcinoma in situ are permitted to participate.~22. The participant has acquired immunodeficiency syndrome (AIDS) or hepatitis, is a human immunodeficiency virus (HIV) carrier, or tested positive for the hepatitis B virus surface antigen (HBsAg) or the hepatitis C virus (HCV) antibody. However, participants who tested negative for HCV antigen or HCV-RNA are permitted to participate.~23. The participant has any of the following abnormal clinical laboratory test values at the start of the run-in period (Visit 1):~    * Creatinine \> 2 mg/dL.~   * Alanine aminotransferase (ALT) or aspartate aminotransferase (AST) \> upper limit of normal (ULN).~   * Bilirubin (Total bilirubin) \> ULN.
