Details and patient eligibility

About

This study aims at evaluating efficacy and safety of berberine- amoxicillin containing quadruple therapy(berberine, amoxicillin, esomeprazole and bismuth) versus tetracycline-furazolidone quadruple therapy (tetracycline, furazolidone, esomeprazole and bismuth) in H. pylori rescue therapy. It is hypothesized that berberine-amoxicillin containing quadruple therapy is non-inferior to tetracycline-furazolidone quadruple therapy. Patients with confirmed failure of H. pylori eradication will be randomized to one of the treatments described above. 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.

Full description

Detailed Description:

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。
