What this trial studies

This is a multi-center, non-randomized, open-label study designed to evaluate the efficacy of the PyloPlus Urea Breath Test (UBT) system in confirming the eradication of Helicobacter pylori infection after treatment. Eligible participants, who have been treated for H. pylori within the past six months, will undergo testing using non-radioactive 13C-Urea and may provide stool samples or undergo endoscopy for additional testing. The results from the PyloPlus UBT will be compared against established methods such as the H. pylori Stool Antigen Test and Rapid Urease Test to assess its accuracy and reliability.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 and older who have been diagnosed with H. pylori and treated within the last six months.

Not a fit: Patients who are pregnant, lactating, or have certain medical conditions that could compromise safety or data quality will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a more accurate and non-invasive method for confirming the eradication of H. pylori infections in patients.

How similar studies have performed: Previous studies have shown success with breath tests for H. pylori, but the PyloPlus UBT system is a novel approach that has not been extensively tested.
