Outcome Measures
Primary Outcomes (1)
Percentage of Heartburn-Free 24-Hour Periods (Day and Night) During 4 Weeks of Treatment
Participants used the Reflux Symptom Questionnaire Electronic Diary (RESQ-eD) every morning upon waking and every evening before going to sleep to document the presence of daytime and nighttime heartburn and regurgitation. The percentage of heartburn-free (HBF) 24-hour periods was calculated for each participant using the following formula: (total 24-hour periods that are heartburn free / total 24-hour periods for which both a daytime and nighttime result is marked) x 100%.
4 Weeks
Secondary Outcomes (1)
Percentage of Participants With ≥1 Sustained Resolution of Heartburn During the 4-Week Treatment Period
4 Weeks
Study Arms (3)
Esomeprazole 40 mg
ACTIVE COMPARATOREsomeprazole 40 mg over-encapsulated tablets, orally, once daily for 4 weeks then esomeprazole placebo-matching capsules, orally, once daily for 2 weeks during the run-in period, followed by esomeprazole 40 mg, over encapsulated tablets, orally, once daily for 4 weeks during the active treatment period.
Vonoprazan 20 mg
EXPERIMENTALEsomeprazole 40 mg over-encapsulated tablets, orally, once daily for 4 weeks then esomeprazole placebo-matching capsules, orally, once daily for 2 weeks during the run-in period, followed by vonoprazan 20 mg, over-encapsulated capsules, orally, once daily for 4 weeks during the treatment period.

Eligibility Criteria
You may qualify if:
- In the opinion of the investigator, the participant is capable of understanding and complying with protocol requirements.
- The participant or, when applicable, the participant's legally acceptable representative signs and dates a written, informed consent form and any required privacy authorization prior to the initiation of any study procedures.
- Is a man or a woman and ≥18 years of age, at the time of the Screening visit.
- Has a documented history of symptoms of both heartburn (burning pain) and acid regurgitation prior to entry into the study.
- The subject has a medical history of ≥ 8 weeks of persistent heartburn symptoms in the presence of regurgitation symptoms (persistent heartburn symptoms defined as heartburn symptoms on ≥ 2 days a week) that are troublesome despite appropriate and correctly performed treatment with a PPI at standard doses.
- Is ≥85% compliant at taking their Run-in medication and completing their e-Diary. Compliance for taking the Run-in medication is defined as the medication provided (esomeprazole and placebo) taken for 85% of the 6 weeks Run-in Period (or on 36 of 42 days of the Run-in Period).Compliance for the e-Diary is defined as the percentage of scheduled assessments that are completed based on 2 assessments per day (daytime and nighttime). For randomization, 85% compliance is required and is defined as 12 of 14 assessments completed over the 7-day period (Day -21 to Day-14) prior to the single blind Placebo Run-in Period.
- Has a partial response to a PPI defined as having heartburn on 2 to 5 days and regurgitation on at least one day of the last week (Week 4) of a 4 week PPI Run-In Period with esomeprazole 40 mg and an increase of at least 2 symptom days of heartburn in the last week of a 2 week Placebo Run-In Period (4 to 7 symptom days) and at least one symptom day with regurgitation compared with the last week of the PPI Run-In Period.
- A female participant of childbearing potential who is sexually active with a nonsterilized male partner agrees to use routinely adequate contraception from signing of informed consent throughout the duration of the study and for 4 weeks after last dose of the study medication.
You may not qualify if:
- Has received any investigational compound within 30 days prior to the Screening Visit.
- Has received vonoprazan in a previous clinical study.
- Is an immediate family member, study site employee, is in a dependent relationship with a study site employee who is involved in conduct of this study (eg, spouse, parent, child, sibling), or may have consented under duress.
- Has, in the judgment of the investigator, clinically significant abnormal hematological parameters of hemoglobin, hematocrit, or erythrocytes at Screening.
- Has a history of erosive esophagitis of Los Angeles (LA) Classification Grade B severity or worse prior to screening or at Screening endoscopy.
- Has a history of or any coexisting diseases affecting the esophagus (eg, Barrett's esophagus, eosinophilic esophagitis, esophageal varices, scleroderma, viral or fungal infection, or esophageal stricture), history of radiation therapy or cryotherapy to the esophagus, caustic trauma, or physiochemical trauma such as sclerotherapy to the esophagus.
- Has current or historical chest pain due to cardiac diseases (eg, within one year).
- Has had surgical treatment for GERD (eg, cardiaplasty), dilation of an esophageal stricture (other than Schatzki ring) or gastric or duodenal surgery, except simple oversew of an ulcer or endoscopic polypectomy of benign polyps.
- Has had an acute upper gastrointestinal hemorrhage within 30 days prior to Screening.
- Has current or historical evidence of Zollinger-Ellison syndrome or other hypersecretory condition.
- Has a documented history (within 6 months prior to screening) of functional dyspepsia (suggested by the presence of one or more of the following symptoms: epigastric pain, postprandial fullness or early satiety), or irritable bowel syndrome or other gastrointestinal diseases which are not acid-related, and therefore, are nonresponsive to gastric acid-blocking treatment.
- Has a documented history of familial adenomatous polyposis.
- Has known intolerance, hypersensitivity or allergies to any PPI or their components (including lansoprazole, dexlansoprazole, omeprazole, rabeprazole, pantoprazole, or esomeprazole), any component of vonoprazan, or antacid(s) selected as rescue medication for this study.
- Has a history of alcohol abuse, illegal drug use, or drug addiction within the 12 months prior to Screening, or regularly consumes \>21 units of alcohol (1 unit = 12 oz/300 mL beer, 1.5 oz/25 mL hard liquor/spirits, or 5 oz/100 mL wine) per week. Participants must have a negative drug screen at Screening.
- Has evidence of a serious uncontrolled concomitant disease including: clinically significant neurologic, cardiovascular, pulmonary, hepatic, renal, metabolic, gastrointestinal, systemic, or endocrine disease or other abnormality (other than the disease being studied), which may impact the ability of the participant to participate or potentially confound the study results.

Takeda makes patient-level, de-identified data sets and associated documents available for all interventional studies after applicable marketing approvals and commercial availability have been received (or program is completely terminated), an opportunity for the primary publication of the research and final report development has been allowed, and other criteria have been met as set forth in Takeda's Data Sharing Policy (see www.TakedaClinicalTrials.com for details). To obtain access, researchers must submit a legitimate academic research proposal for adjudication by an independent review panel, who will review the scientific merit of the research and the requestor's qualifications and conflict of interest that can result in potential bias. Once approved, qualified researchers who sign a data sharing agreement are provided access to these data in a secure research environment.
