Description

Inclusion Criteria:

  1. The participant has been treated with standard-dose or higher-than-standard-dose PPI until immediately before the start of the Observation Phase.
  2. Outpatient (in principle)
  3. At the endoscopy scheduled for the Observation Phase (Visit 2), the participant must have endoscopically confirmed reflux esophagitis of Grade A to D, as defined by the LA classification grading system, which remains insufficiently controlled with standard-dose or higher-than-standard-dose PPI therapy.
  4. The participant showed good compliance to the study medication in the Observation Phase (compliance rate 80% or more).

Exclusion Criteria:

  1. Participants with an esophagus-related complication (eosinophilic esophagitis, esophageal varices, scleroderma, viral or fungal infection, esophageal stenosis, etc.), a history of radiotherapy or cryotherapy of the esophagus, a caustic or physiochemical trauma (esophageal sclerotherapy, etc.). However, participants with Schatzki's ring (mucosal tissue ring around inferior esophageal sphincter) or Barrett's esophagus are allowed to be included.
  2. Participants who have received surgery or treatment affecting gastroesophageal reflux (cardioplasty, dilation of esophageal stenosis [excluding Schatzki's ring], etc.), or who have a history of surgery of stomach or duodenum (excluding removal of benign polyp under endoscopy)
  3. Participants who have acute upper gastrointestinal bleeding, gastric or duodenal ulcer (mucosal defect with white coating) at the start of the Observation Phase (Visit 1) or at endoscopy during the Observation Phase (Visit 2) . However, participants with gastric or duodenal erosions are allowed to be included.
  4. Participants with a previous or current history of Zollinger-Ellison syndrome, or other gastric acid hypersecretion disorders.
