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

Phase 4

Completed

• Conditions: Helicobacter Pylori Infection; Chronic Gastritis
• Interventions: Drug: Berberine; Drug: Vonoprazan; Drug: Rabeprazole; Drug: Amoxicillin; Drug: Bismuth; Drug: Clarithromycin

• Registration Number: NCT05014334
• Lead Sponsor: Xijing Hospital of Digestive Diseases

Brief Summary

The purpose of this study is to assess the efficacy and safety of berberine, amoxicillin and vonoprazan containing triple therapy in Helicobacter Pylori first-line eradication. It is hypothesized that berberine hydrochloride, amoxicillin and vonoprazan triple therapy is non-inferior to bismuth-containing quadruple therapy or vonoprazan -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.

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.

Primary Outcome Measures

Name	Time	Method
H pylori eradication rates	28 days after treatment	The primary end point of this study is H.pylori eradication,established by negative urea breath test，rapid urease test or helicobacter pylori stool antigen test 28 days after the end of treatment.

Secondary Outcome Measures

Name	Time	Method
symptoms effective rate	14 days of treatment, and 28 days after treatment	Evaluation effective rate of symptoms 2 weeks of treatment and 4 weeks after the end of treatment.; Symptom effective rate =（total score before treatment - total score after treatment）/total score before treatment x 100%.; Total score = frequency + severity.; Frequency score is calculated by all the frequency of heartburn, reflux, abdominal pain, and flatulence.; Severity is accumulated by the degree of symptoms described above, which is divided to 4 degree as 0 presenting none, and 3 presenting most severe
adverse events	14 days of treatment, and 28 days after treatment	Participants with Adverse Events as a Measure of Safety and Tolerability.The common side effects of the study include headache, dizziness, skin rash, other gastrointestinal disorders, pyrexia, cough and back pain.
