Helicobacter Pylori Eradication With Different Bismuth Quadruple Therapies

April 6, 2021 updated by: Yongquan Shi, Xijing Hospital of Digestive Diseases

Comparison of Efficacy of Bismuth Potassium Citrate, Pectin Bismuth Capsules, and Pectin Bismuth Granules in the Treatment of Helicobacter Pylori (Hp) First-line Quadruple Regimen: a Multicenter, Randomized, Prospective, Comparative Clinical Trial

This study aims to compare efficacy and safety of bismuth-containing quadruple therapy（with rabeprazole amoxicillin clarithromycin）of different kinds of bismuth（Bismuth potassium citrate, pectin bismuth capsules, pectin bismuth particles）in H. pylori first-line eradication. It is hypothesized that different bismuth containing quadruple therapies have comparable eradication efficacy and safety. Patients with confirmed H. pylori positive status will be randomized to one of the treatments described above. At week 2and 6 follow-up visits, a urea breath test(UBT) will be performed to confirm eradication.

Study Overview

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The study will include three phases: screening, treatment and follow-up.Screening: this phase will last a maximum of 28 days and subjects eligibility will be evaluated after informed consent signature. Endoscopy and Urea Breath 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 12 and 14.Follow-up: includes two visits. approximately 14 days of treatment and 28 days after the end of treatment. Eradication of H. Pylori will be confirmed through urea breath test(UBT).

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
helicobacter pylori eradication
Time Frame: 28 days after treatment]
The primary end point of this study is H.pylori eradication,established by negative [13C] urea breath test 28 days after the end of eradication.
28 days after treatment]

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
symptoms effective rates
Time Frame: 14 days of treatment, and 28 days after treatment
symptoms effective rates 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 x100%. 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 3presenting most severe
14 days of treatment, and 28 days after treatment

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
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.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
