Summary

This study is a randomized, open-label, parallel-group clinical trial designed to compare two 14-day dual therapies for the eradication of Helicobacter pylori (H. pylori) infection. Participants will be randomly assigned to receive either tegoprazan 50 mg twice daily plus amoxicillin 1 g three times daily, or vonoprazan 20 mg twice daily plus amoxicillin 1 g three times daily. The primary purpose of this study is to evaluate whether the tegoprazan-based regimen is non-inferior to the vonoprazan-based regimen in terms of H. pylori eradication rates. Eradication will be assessed 4 to 8 weeks after completing therapy using a \^13C-urea breath test. Secondary objectives include assessing treatment-related adverse events, tolerability, and medication adherence. This study involves adult participants with confirmed H. pylori infection. All study medications are orally administered, and both regimens use drugs with well-established safety profiles. The study is investigator-initiated and conducted at Hangzhou First People's Hospital.
