About this study

Official title: Vonoprazan Fumarate in Combination With Amoxicillin for the First-line Eradication - a Multicenter, Randomized, Parallel Controlled Study

Helicobacter pylori infection is closely related to gastritis, peptic ulcer, mucosa-associated lymphoid tissue lymphoma and gastric cancer. Eradication of HP can significantly improve and reduce HP-related diseases. International and domestic guidelines recommend a 10-14 day quadruple regimen containing bismuth as first-line treatment, achieving an eradication rate of more than 80%. However, some disadvantages of these quadruple regimens, such as severe adverse reactions, high medical costs and low compliance, prevent their application in clinical practice. Studies at home and abroad have shown that high-dose proton pump inhibitors combined with amoxicillin can be used as the first-line treatment for HP eradication, with good efficacy and compliance and low rate of adverse reactions. And because it is a single antibiotic therapy, we do not expect this regimen to increase antibiotic resistance rates for HP. The maintenance of gastric PH > 6 is one of the key factors for HP eradication. The acid inhibition effect of proton pump mainly depends on the degree of individual metabolism of proton pump. Vonoprazan fumarate, a new competitive potassium acid blocker, is not affected by gene polymorphism, and has the advantage of stronger and longer inhibition effect on gastric acid compared with proton pump inhibitors. In most parts of China, HP is characterized by high infection rate and antibiotic resistance rate, requiring higher eradication rate and safety regimen. This study compared the efficacy and safety of vonoprazan fumarate combined with amoxicillin and bismuth-containing quadruple regimen in first-line HP eradication, in order to find a more suitable regimen for HP eradication.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing vonoprazan fumarate + amoxicillin and Esomeprazole +Amoxicillin+Clarithromycin+Bismuth potassium citrate in people with Helicobacter Pylori Eradication Rate, run by Sixth Affiliated Hospital, Sun Yat-sen University.

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

Who may be eligible to take part?

The sponsor lists 1 inclusion and 1 exclusion criteria. 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 17 Feb 2022. Status can change between updates, so confirm with the study contact before making plans.

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?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

H. pylori eradication rate (time frame: 6 week). 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?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Feb 2022.
