About this study
Official title: Comparison of 14-day Sequential and Hybrid Therapies for H Pylori Infection
Primary: To evaluate efficacy of 14 day 2-phase sequential therapy given in two forms. One in which the first component consists of a proton pump inhibitor and amoxicillin given for 7 days followed by the PPI, clarithromycin and metronidazole for 7 days. The alternate will be similar with the exception that the amoxicillin will be continued throughout the 14 days. The secondary endpoint is to evaluate the effectiveness of therapy in relation to antibiotic resistance.
Read the detailed description
The purpose of this study is to test whether the 14-day sequential therapy ( esomeprazole plus amoxicillin dual therapy for 7 days followed by triple therapy with esomeprazole, clarithromycin, and metronidazole for 7 days) or 14-day hybird therapy (esomeprazole plus amoxicillin dual therapy for 7 days followed by quadruple therapy with esomeprazole, amoxicillin, clarithromycin, and metronidazole for 7 days) can achieve an eradication rate equal to or more than 95%.
A total of 240 subjects will be asked to participate in this study.
- pylori-infected patients are randomized to either a 14-day sequential therapy (esomeprazole 40 mg and amoxicillin 1 g twice daily for 7 days followed by esomeprazole 40 mg, clarithromycin 500 mg and metronidazole 500 mg twice daily for 7 days) or a hybrid therapy (esomeprazole 40 mg and amoxicillin 1 g twice daily for 7 days followed by esomeprazole 40 mg, amoxicillin 1 g, clarithromycin 500 mg and metronidazole 500 mg twice daily for 7 days).
Eradication efficacy is assessed by a follow-up endoscopy with rapid urease test and histological examination eight weeks after the end of anti-H. pylori therapy. The eradication rates of the two study groups will be compared.
A successful regimen is defined as a regimen achieving an eradication rate equal to or more than 95%.

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?
Yes. Results are posted in the registry (first posted 6 May 2011). 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?
Number of Participants in Which H. Pylori Was Eradicated (time frame: Dec 2010). 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 21 Sep 2015; AzTrials last refreshed its copy on 7 Nov 2026.
