What this trial studies

This trial aims to compare the effectiveness and safety of three different treatment regimens for Helicobacter pylori infection: a 14-day bismuth-amoxicillin-vonoprazan triple therapy, a 14-day vonoprazan dual therapy, and a 14-day rabeprazole triple therapy. The study will recruit 780 adult patients from ten medical centers in Taiwan and will utilize a randomized, open-label design. Participants will be monitored for drug adherence and adverse events, with H. pylori status assessed through a breath test six weeks post-treatment. The trial will also explore the impact of antibiotic resistance and specific genetic factors on treatment efficacy.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 and older who are infected with Helicobacter pylori.

Not a fit: Patients who have previously undergone treatment for Helicobacter pylori or have certain medical conditions, such as severe liver cirrhosis or malignancies, may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide more effective treatment options for patients with Helicobacter pylori infection.

How similar studies have performed: Other studies have shown varying success with different treatment regimens for Helicobacter pylori, making this approach both relevant and necessary.
