A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study evaluates the effectiveness and safety of dual and quadruple treatment regimens for Helicobacter pylori eradication over varying durations of 7, 10, and 14 days. Participants will be randomly assigned to receive either a dual regimen of vonoprazan and amoxicillin or a quadruple regimen that includes vonoprazan, amoxicillin, tetracycline, and bismuth. The success of the treatment will be assessed using a 13C-urea breath test six weeks after completion of the regimen, with a focus on eradication rates, adverse reactions, and patient adherence.

Why it matters

Potential benefit: If successful, this study could provide more effective treatment options for patients suffering from Helicobacter pylori infections.

How similar studies have gone: Other studies have shown varying success with different treatment regimens for Helicobacter pylori, but this specific comparison of treatment durations is relatively novel.
