About this study

Strongly evidence supports that H. pylori eradication is an effective approach to reduce the incidence of those pathologies. However, due to the increasing resistance rates to antibiotics, failures of H. pylori eradication get more and more common. Thus, rescue therapy for persistent H. pylori infection is becoming a grand challenge the investigators have to face.

Being tested
7-day triple regimen guided by AST, 10-day triple regimen guided by AST, 14-day triple regimen guided by AST

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • 7-day triple regimen guided by ASTOther

    Patients in this group will receive a 7-day triple regimen to eradicate H. pylori. The regimen is consist of a PPI and 2 susceptible antibiotics which are determined by AST. The susceptibility of amoxicillin, clarithromycin, metronidazole, tinidazole,levofloxacin, furazolidone and tetracycline will be evaluated.

  • 10-day triple regimen guided by ASTOther

    Patients in this group will receive a 10-day triple regimen to eradicate H. pylori. The regimen is consist of a PPI and 2 susceptible antibiotics which are determined by AST. The susceptibility of amoxicillin, clarithromycin, metronidazole, tinidazole,levofloxacin, furazolidone and tetracycline will be evaluated.

  • 14-day triple regimen guided by ASTOther

    Patients in this group will receive a 14-day triple regimen to eradicate H. pylori. The regimen is consist of a PPI and 2 susceptible antibiotics which are determined by AST. The susceptibility of amoxicillin, clarithromycin, metronidazole, tinidazole,levofloxacin, furazolidone and tetracycline will be evaluated.

What is being measured

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

  1. The different rate of H. pylori eradication among 3 different course of treatments (7-day, 10-day and 14-day) guided by AST in intention-to-treat (ITT) analysis.

    Measured: 9 months

  2. The different rate of H. pylori eradication among 3 different course of treatments (7-day, 10-day and 14-day) guided by AST in per-protocol (PP) analysis.

    Measured: 9 months

Secondary outcomes (2)
  1. the rate of improving dyspepsia symptoms after H. pylori eradication

    Measured: 9 months

  2. the rate of adverse events happening

    Measured: 9 months

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing 7-day triple regimen guided by AST, 10-day triple regimen guided by AST and 14-day triple regimen guided by AST in people with Therapeutic Duration and Helicobacter Pylori, run by Shandong 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 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

What does the primary outcome measure?

The different rate of H. pylori eradication among 3 different course of treatments (7-day, 10-day and 14-day) guided by AST in intention-to-treat (ITT) analysis. (time frame: 9 months). The study lists 2 primary outcomes in all. 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?
