About this study

  1. pylori is an infection of the stomach that can cause chronic gastritis, gastric cancer and peptic ulcer disease. The goal of this study is to screen people for this infection and offer treatment for those who test positive for the infection. By treating those who are positive for H. pylori, there is an opportunity to prevent gastritis, peptic ulcer disease, and even gastric cancer.
Being tested
PYTEST® 14C-Urea Breath Test, VOQUEZNA® Triple Pak®

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • PYTEST® 14C-Urea Breath TestDrug

    FDA-approved radiolabeled urea capsule used in the PYtest® 14C-Urea Breath Test for non-invasive detection of H. pylori. Participants ingest the capsule, and breath samples are collected and analyzed to determine infection status.

  • VOQUEZNA® Triple Pak®Drug

    FDA-approved combination therapy for H. pylori infection, consisting of:

    Vonoprazan tablets 20 mg (1 tablet twice daily for 14 days) Amoxicillin 500 mg (2 tablets twice daily for 14 days) Clarithromycin 500 mg (1 tablet twice daily for 14 days) Medications are dispensed by the study team at the time of diagnosis.

Study groups in NCT07224035
Study groupRoleWhat they receive
Helicobacter Pylori Screening and TreatmentExperimentalParticipants in this single-arm study will undergo screening for Helicobacter pylori (H. pylori) using the PYtest® 14C-Urea Capsule Breath Test. This FDA-approved, non-invasive diagnostic method involves swallowing a radiolabeled urea capsule. If gastric urease from H. pylori is present, the urea is hydrolyzed to produce carbon dioxide and ammonia. Ten minutes after ingestion, a breath sample is collected in a balloon and transferred into a collection fluid to trap the labeled carbon dioxide. The sample is analyzed using a liquid scintillation counter to determine infection status. Participants who test positive will receive VOQUEZNA® Triple Pak® therapy, dispensed by the study team at the time of diagnosis. Phathom Pharmaceuticals will supply the medications (which include complete medication package insert), but the study team hold and dispenses medications.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Percent of participants diagnosed with Helicobacter pylori using PYTEST® breath test at baseline

    This measure determines the percent of participants who test positive for Helicobacter pylori at baseline. This is done using the PYTEST® 14C-Urea Breath Test. Participants will receive a diagnosis on-site, approximately 30 minutes after administration of urea capsule. This will allow immediate treatment free of charge (VOQUEZNA® Triple Pak®) initiation for positive eligible participants.

    Measured: Baseline

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing PYTEST® 14C-Urea Breath Test and VOQUEZNA® Triple Pak® in people with H Pylori Infection and H Pylori Gastritis, run by University of Miami at 1 site 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 1 inclusion and 31 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 16 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Percent of participants diagnosed with Helicobacter pylori using PYTEST® breath test at baseline (time frame: Baseline). 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 16 Oct 2026.
