A RCT of the Efficacy of Vonoprazan 20mg QD in the Treatment of Helicobacter Pylori Infection (VATH-1)

November 23, 2022 updated by: ZhangXiaofeng, First People's Hospital of Hangzhou

A RCT of the Efficacy of Vonoprazan 20mg QD Combined With Amoxicillin 750mg QID in the Treatment of Helicobacter Pylori Infection

The treatment of helicobacter pylori is very important. The routine treatment is quadruple therapy. In recent years, double therapy has appeared and the curative effect is fair. However, antacid generally uses proton pump inhibitor. The proton pump inhibitor needs double dose to achieve good antacid curative effect. The effect of vonoprazan used for inhibiting gastric acid is better than proton pump inhibitor. At present, many studies use vonoprazan instead of common proton pump inhibitor, but almost all use double dose of vonoprazan. In the previous study, we found that the effect of double dose of proton pump inhibitor can be achieved with 20mg QD of vonoprazan. Therefore, in this study, 20mg QD of vonoprazan was used to replace the double dose of proton pump inhibitor to observe the antibacterial effect of vonoprazan on Helicobacter pylori.

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. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 70 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Patients aged ≥18 years with Hp-positive first sterilization were included in this study. Before treatment, the existence of Helicobacter pylori can be confirmed by one or more of the following methods: rapid urease test, Hp culture, 13C urea breath test, 14C urea breath test and stool Hp antigen test.

The main exclusion criteria include acute upper gastrointestinal bleeding, active gastric or duodenal ulcer, acute gastric or duodenal mucosal lesions, previous eradication treatment of Helicobacter pylori, penicillin/furazolidone allergy, surgery that may affect gastric acid secretion (upper gastrointestinal resection or vagotomy), Zollinger-Ellison syndrome or other hypergastric acid secretion diseases, severe neurological, cardiovascular, pulmonary, liver, renal, metabolic, gastrointestinal, urological, etc. Any fertile woman must use proper contraception. All subjects provided written informed consent before participating in the study.

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
Percentage of Helicobacter Pylori Positive (HP+) Participants With Successful HP Eradication at Week 4 Post-Treatment
Time Frame: Week 4 post-treatment
HP infection status will be determined by ^13C Urea Breath Test (^13C-UBT). The urea breath test is used to detect infection with HP, a bacteria associated with stomach ulcers, by testing individual breath samples in a central laboratory.
Week 4 post-treatment
