A Phase 4 interventional study of PYTEST® 14C-Urea Breath Test and VOQUEZNA® Triple Pak® in H Pylori Infection, H Pylori Gastritis and Gastric Cancer, sponsored by University of Miami. Completed at 1 site in United States. Open to participants aged 18 Years and older, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-09-30.
Sponsored by University of Miami · Phase 4, Interventional, and Screening
H. 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.
2,850 studies on the registry are indexed under Stomach Neoplasms; 863 are open to participants now.
This study's enrollment of 430 is above the median of 67 across 2,095 interventional studies indexed under Stomach Neoplasms.

Exclusion Criteria:
Participants 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.
Drug: PYTEST® 14C-Urea Breath Test · Drug: VOQUEZNA® Triple Pak®
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.
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.
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.
