Helicobacter Rescue Therapy With Vonorazon and Amoxicillin Dual Therapy Versus Bismuth-containing Quadruple Therapy
Rescue Therapy for Helicobacter Pylori Eradication: A Randomized and Non-inferiority Trail of Vonorazon and Amoxicillin Dual Therapy Versus Bismuth-containing Quadruple Therapy
Study Overview
Status
Intervention / Treatment
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 14 and 16.
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.

Measure Description |
Time Frame |
---|---|---|
adverse events
Time Frame: 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.
|
14 days of treatment, and 28 days after treatment
|
symptoms effective rates
Time Frame: 14 days of treatment, and 28 days after treatment
|
symptoms improvement rates Evaluation improvement rate of symptoms 2 weeks of treatment and 4 weeks after the end of treatment.
Symptom improvement rate =# t total score before treatment - total score after treatment#/total score before treatment x100%.
Total score = frequency + severity.Frequency score is calculated by all the frequency of heartburn, reflux, abdominal pain, and flatulence, etc. 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
