Tegoprazan Plus Amoxicillin BID vs TID Regimens for H. Pylori Eradication（Frequency Adjusted Same-dose Therapy for H. Pylori）
China240 participantsStarted 2025-11-20
Plain-language summary
This study is designed to evaluate two different tegoprazan-based dual therapy regimens for the treatment of Helicobacter pylori (H. pylori) infection. All participants will receive tegoprazan 50 mg twice daily for 14 days, combined with one of two amoxicillin dosing schedules that contain the same total daily dose of 3 grams of amoxicillin.
One group will receive amoxicillin 1 gram three times daily (TID), which is the standard regimen. The other group will receive amoxicillin 1.5 grams twice daily (BID), an alternative schedule that may improve convenience and treatment adherence while maintaining the same total daily antibiotic amount.
A total of 240 adults with confirmed H. pylori infection will be randomly assigned to one of the two treatment groups. The main goal of the study is to compare the H. pylori eradication rates between the two regimens. Eradication will be assessed 4 to 8 weeks after completing therapy using a ¹³C-urea breath test. Safety, tolerability, and medication adherence will also be monitored.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
