Trial summary

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. Read more about this study

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.

About this study

Official title: 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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Percentage of Helicobacter Pylori Positive (HP+) Participants With Successful HP Eradication at 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.

    Measured: Week 4 post-treatment

What is this clinical trial studying?

A Phase 4 study testing Vonoprazan Tablets, Amoxicillin Capsules and Esomeprazole in people with Vonoprazan and Helicobacter Pylori Infection, run by First People's Hospital of Hangzhou at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 29 Nov 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Hongzhang Shen (057156005600, sakshen@126.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Percentage of Helicobacter Pylori Positive (HP+) Participants With Successful HP Eradication at Week 4 Post-Treatment (time frame: Week 4 post-treatment). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?
