- Female participants who have experienced menarche must have a negative pregnancy test and will be counseled on pregnancy avoidance.
Who cannot join
- The participant has used prescription or non-prescription proton pump inhibitors (PPIs) or histamine-2 receptor antagonist (H2RAs) within 7 days prior to randomization or requires use during the Treatment Period.
- The participant has used sucralfate, or antacids within 1 day prior to randomization or requires their use during the Treatment Period.
- The participant has received other agents affecting digestive organs, including muscarinic antagonists (eg, hyoscyamine), prokinetics, oral anticholinergic agents, prostaglandins, bismuth from 30 days prior to Day 1 or requires their use during the course of the study.
- The participant has received atazanavir sulfate or rilpivirine hydrochloride from 5 days prior to Day 1 or requires their use during the course of the study.

- The participant has used any prescription or over-the-counter medications (including herbal or nutritional supplements), other than those already excluded in criteria 1 to 5 above, within 14 days before the first dose of study drug or throughout the study. That is, unless the medication(s) is permitted by the sponsor following a review of available data which confirms concomitant administration of the medication is unlikely to affect either the safety of the participant or the pharmacokinetics of vonoprazan.
- The participant has consumed grapefruit or grapefruit juice, Seville orange or Seville orange-containing products (eg, marmalade), or other food products that may be CYP3A4 inhibitors (eg, vegetables from the mustard green family [kale, broccoli, watercress, collard greens, kohlrabi, Brussels sprouts, mustard] and charbroiled meats) within 7 days (or 5 half-lives) before the first dose of study drug or throughout the study.
- The participant has positive results at screening for human immunodeficiency virus, hepatitis B virus, or hepatitis C virus (HCV).
- The participant has severe renal impairment (estimated glomerular filtration rate < 30 mL/min).
- The participant has moderate to severe hepatic impairment (Child-Pugh Class B and Child-Pugh Class C).
- The participant has any of the following abnormal laboratory test values at the start of the Screening Period:
- Creatinine levels: >0.8 mg/dL (>70 μmol/L).
- Alanine aminotransferase (ALT) or aspartate aminotransferase (AST) >2 × the upper limit of normal (ULN) or total bilirubin >2 × ULN (except participants with Gilbert Syndrome).
- In the opinion of the investigator, the participant is not suitable for entry into the study.

What is being measured
The primary outcome is the main question the study is designed to answer.
Maximum Drug Concentration at Steady-state (Cmax,ss) of Vonoprazan
Plasma pharmacokinetic (PK) parameters were estimated using a non-linear mixed effects model and were determined from the concentration-time data for all evaluable participants. Actual sampling times, rather than scheduled or nominal sampling times, were used in all computations using sampling time. Data presented based on collections on both Day 7 and Day 14.
Measured: Day 7: pre-dose, 0.5 to 1.5 hour and 2.5 to 3.5 hours post dose; Day 14: pre-dose, 1 to 2 hours and 3 to 4 hours post dose
Area Under the Plasma Concentration-time Curve During the Dosing Interval τ at Steady State (AUCτ,ss) of Vonoprazan
Plasma PK parameters were estimated using a non-linear mixed effects model and were determined from the concentration-time data for all evaluable participants. Actual sampling times, rather than scheduled or nominal sampling times, were used in all computations using sampling time. Data presented based on collections on both Day 7 and Day 14.
Measured: Day 7: pre-dose, 0.5 to 1.5 hour and 2.5 to 3.5 hours post dose; Day 14: pre-dose, 1 to 2 hours and 3 to 4 hours post dose
Apparent Oral Clearance (CL/F) at Steady State of Vonoprazan
Oral PK parameters were estimated using a non-linear mixed effects model and were determined from the concentration-time data for all evaluable participants. Actual sampling times, rather than scheduled or nominal sampling times, were used in all computations using sampling time. Data presented based on collections on both Day 7 and Day 14.
Measured: Day 7: pre-dose, 0.5 to 1.5 hour and 2.5 to 3.5 hours post dose; Day 14: pre-dose, 1 to 2 hours and 3 to 4 hours post dose
Apparent Central Volume of Distribution (Vz/F) at Steady State of Vonoprazan
Plasma PK parameters were estimated using a non-linear mixed effects model and were determined from the concentration-time data for all evaluable participants. Actual sampling times, rather than scheduled or nominal sampling times, were used in all computations using sampling time. Data presented based on collections on both Day 7 and Day 14.
Measured: Day 7: pre-dose, 0.5 to 1.5 hour and 2.5 to 3.5 hours post dose; Day 14: pre-dose, 1 to 2 hours and 3 to 4 hours post dose

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Vonoprazan in people with Gastroesophageal Reflux Disease, run by Phathom Pharmaceuticals, Inc. at 13 sites in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 6 inclusion and 19 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 19 Dec 2024. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 13 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 19 Dec 2024). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Maximum Drug Concentration at Steady-state (Cmax,ss) of Vonoprazan (time frame: Day 7: pre-dose, 0.5 to 1.5 hour and 2.5 to 3.5 hours post dose; Day 14: pre-dose, 1 to 2 hours and 3 to 4 hours post dose). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Dec 2024.
