Study on The Efficacy and Safety of Vonoprazan-containing Berberine Triple Therapy in Helicobacter Pylori First-Line Eradication

Study on The Efficacy and Safety of Berberine,Amoxicillin and Vonoprazan Containing Triple Therapy in Helicobacter Pylori First-Line Eradication

The purpose of this study was to evaluate the efficacy and safety of the triple therapy of berberine hydrochloride, vonorasan and amoxicillin for the primary eradication of Helicobacter pylori.It is hypothesized that berberine hydrochloride, amoxicillin and vonoprazan triple therapy is non-inferior to bismuth-containing quadruple therapy.Patients diagnosed with H. pylori infection will be randomly divided into one of the above treatments. At week 6 follow-up visits, a urea breath test，rapid urease test or helicobacter pylori stool antigen test will be performed to confirm eradication.

The study will include three phases: screening, treatment and follow-up. Screening: this phase will last a maximum of 14 days and subjects eligibility will be evaluated after signing informed consent. One of urea breath test，rapid urease test or helicobacter pylori stool antigen test will be performed in addition to the baseline routine evaluations.

Treatment: Subjects are randomly assigned to treatment and will be treated for 14 days. A randomization visit will take place on Day 0 and an end-of-treatment visit will take place between day 13 and 17.

Follow-up: includes one visits. Approximately 28 days after the end of treatment. Eradication of H. Pylori will be confirmed by one of urea breath test，rapid urease test or helicobacter pylori stool antigen test.

Inclusion Criteria:

1. Age between 18~70,both gender.
2. Patients with upper gastrointestinal symptoms and with documented H.pylori infection who did not receive Helicobacter pylori eradication treatment;
3. Patients are willing to receive eradication treatment.
4. Women of childbearing age were required to use medically acceptable contraceptive methods during and 30 days after the trial.

Exclusion Criteria:

1. Patients are excluded if they have previously used antibiotics to eradicate adequately recorded infection with H. pylori.
2. Patients with contraindications or allergies to the study drug.

4. Constant use of anti-ulcer drugs ( including taking proton-pump.inhibitors(PPI) within 2 weeks before the [13C] urea breath test),antibiotics or bismuth complexes (more than 3 times /1 month before screening).
5. Patients were diagnosed with gastroduodenal ulcer and MALTlymphoma.
6. Pregnant or lactating women.
7. Underwent upper gastrointestinal Surgery.
8. Patients with moderate to severe dysplasia or high degree of intraepithelial neoplasia.
