Detailed Description

Helicobacter pylori（H.pylori）is a gastric pathogen, related to various gastrointestinal disorders. It's now a consensus of experts that H.pylori infection should be treated once it is recognized. Vonoprazan and high-dose amoxicillin dual therapy is a potential H.pylori eradication regimen. It provides a satisfactory eradication rate of 90%. Nevertheless,it has certain limitations, including a series of problems such as low eradication rate and more side effects of eradication in recurrent patients. The main side effects of the dual therapy for eradication are related symptoms of gastric motility deficiency and indigestion, such as bloating, abdominal pain, belching, acid reflux, etc. Combining traditional Chinese medicine may be one of the effective ways to solve the above problems.This study aims to compare the efficacy of Zuojin Wan combined with vonoprazan and high-dose amoxicillin dual therapy,with that of vonoprazan and high-dose amoxicillin dual therapy.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change from Baseline in functional dyspepsia symptoms at 6 weeks
Time Frame: Baseline and Week 6
Dyspepsia symptoms on days 7,14 and 42 were assessed using Likert scale； Scale tittle:Symptom frequency and severity criteria table； The minimum value：8；the maximum value：40； Higher scores mean a worse outcome.
Baseline and Week 6
Change in Traditional Chinese Medicine syndromes from Baseline to 6 weeks
Time Frame: Baseline and Week 6
Traditional Chinese Medicine syndromes on days 7,14 and 42 were assessed using Traditional Chinese Medicine syndrome integral scale.Scale tittle:Traditional Chinese Medicine syndrome integral scale; The minimum value：0；the maximum value：30； Higher scores mean a worse outcome.
Baseline and Week 6

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Patients' drug compliance
Time Frame: day 1 and day 14
Patients' drug compliance was assessed using medication possession ratio
day 1 and day 14
