Yes

E.2.3.1

Full title, date and version of each sub-study and their related objectives

Pharmacogenomics research study and long term storage of samples
Subject eligible for randomization to treatment will be asked to partecipate to an optional study.
At visit 4, Subject that agree to partecipate to this optional study will be asked to sign a separate informed consent form in order to store the remaining DNA sample from the CYP2C19 genotyping and to collect additional blood samples for ribonucleic acid (RNA) isolation.
DNA forms the basis for the genes that make the body produce proteins such as enzymes, drug transporters or drug targets, and may be evaluated for the genetic contribution how the drug is broken down, or how the drug affects the body. This is called a “Pharmacogenomics research study.” Specific purposes of this study include:
- Identifying genetic reasons why certain people respond differently to vonoprazan.
-Finding out more information about how vonoprazan works.
-Generating information needed for research, development, and regulatory approval of tests to predict response to vonoprazan.
- Identifying variations in genes related to the biological target of vonoprazan.
This information may be used, for example, to develop a better understanding of the safety and efficacy of vonoprazan and other study medications, understanding of disease/condition being studied and for improving the efficiency, design and study methods of future research studies

E.3

Principal inclusion criteria

Subjects will be eligible for participation in the study if they:
-have a documented history of symptoms of both heartburn and acid regurgitation prior to entry into the study
- have a history of persistent heartburn and/or regurgitation symptoms that are troublesome despite an adequate course of PPI treatment;
- continue to have symptoms of heartburn (and regurgitation) following 4 weeks treatment with a high dose of esomeprazole 40 mg QD during the Run-in Period;
- have symptoms of heartburn which increases following a 2-week Washout Period in the presence of regurgitation prior to randomization. Patients with mild (LA grade A) esophagitis are permitted to enter the study.

E.4

Principal exclusion criteria

- Subjects who have hypersensitivity to vonoprazan or related compounds
- a history or any coexisting diseases affecting the esophagus;
-‘alarm features’ in symptomatology pointing to a possible malignant disease of the GI tract;
- current or historical chest pain due to cardiac disease;
-a history of surgical treatment for GERD;
- dilation of an esophageal stricture or gastric or duodenal surgery.
- Subjects who have a documented history of functional dyspepsia or irritable bowel syndrome or other gastrointestinal diseases which are not acid-related, and therefore, are nonresponsive to gastric acid-blocking treatment.
- Subjects who have levels of AST,ALT or total bilirubin > ULN.
- those who have a documented history of familial adenomatous polyposis, active gastric or duodenal ulcers or acute upper gastrointestinal hemorrhage within 30 days prior to screening and any other co-morbidities or any significant results from physical examinations, or clinical laboratory results as deemed by the investigator.
