About this study

Official title: A Prospective, Multi-center, Randomized, Open-label, Parallel Design Clinical Trial to Compare 10-day Sequential Therapy and 14-day Modified Bismuth Quadruple Therapy for the Eradication of Helicobacter Pylori in Korea

  1. To compare 10-day sequential therapy and 14-day modified bismuth quadruple therapy and to establish more effective first-line regimen for the eradication of Helicobacter pylori in Korea.
  2. To evaluate the effect of H. pylori eradication therapy on the symptom improvement of functional dyspepsia
Read the detailed description

Emerging evidence shows that the eradication rate of proton pump inhibitor (PPI)-based triple therapy for the first-line treatment of Helicobacter pylori has decreased. The reason for the decrease in the efficacy of PPI-based triple therapy is mainly due to the increase in the resistance against clarithromycin. Sequential therapy seems to be more effective than the PPI-based triple therapy, however, the eradication rate of sequential therapy in Korea, which is mostly under 80%, is still not satisfactory. Modified bismuth quadruple therapy which replace metronidazole with amoxicillin (contained PPI, bismuth, tetracycline and amoxicillin) can be a promising regimen because the antibiotic resistance rate of tetracycline and amoxicillin are relatively low in Korea and amoxicillin is more easy to take in comparing with metronidazole. Therefore, the aim of this study is to compare 10-day sequential therapy and 14-day modified bismuth quadruple therapy and to establish more effective first-line regimen for the eradication of Helicobacter pylori in Korea.

In addition, previous studies reported that H. pylori infection also associated with functional dyspepsia (FD) and recommended H. pylori eradication in patients with FD. However, until now, there was no randomized prospective study in Korea, therefore the another aim of this study is to evaluate the effect of H. pylori eradication therapy on the symptom improvement of FD.

Questions about this trial

What is this clinical trial studying?

A study testing Pantoprazole, Amoxicillin and Clarithromycin in people with Helicobacter Pylori Infection, run by Seoul National University Bundang Hospital at 1 site in South Korea.

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 5 inclusion and 10 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: finished, as of the sponsor's last update on 13 May 2019. 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 South Korea. 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.

Are results available for this study?

Yes. Results are posted in the registry (first posted 13 May 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Counts of Participants With Successful H. Pylori Eradication (time frame: 4 weeks after termination of eradication therapy, up to 6 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02159976, which also lists 1 linked publication.

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 13 May 2019; AzTrials last refreshed its copy on 26 Oct 2026.
