About this study

Official title: Sequential Versus Concomitant Therapy for Helicobacter Pylori Infection

Helicobacter pylori is a bacteria that infects the lining of the stomach and is associated with ulcers. Helicobacter pylori may also increase the long-term risk of developing certain forms of gastric cancer. Curing this infection generally requires that patients take 2 or more antibiotic medications and a stomach acid suppressing medication for about two weeks. Current treatments do not always cure the infection and a new treatment is being tested in this study. The drugs involved in the new 4 drug treatment have been widely used for treatment of this infection. It remains unknown what is the best and most cost effective way to give them. This study will compare three different ways of using these drugs.

Subjects must have active Helicobacter pylori infection in order to participate in this study.

Read the detailed description

The purpose of this study is to compare different methods of giving combination drug therapy for treating Helicobacter pylori infection of the stomach. The entire study will last less than 2 years. Each subject will be participating in the study for approximately 60 days.

A total of 360 subjects will be asked to participate in this study.

Before participating in this study, subject's must have undergone to confirm the presence and to assess the susceptibility of Helicobacter pylori. Qualified subjects will receive 4 drugs which are to be taken as part of the study treatment: an acid suppressing drug (name), amoxicillin, clarithromycin and metronidazole. The doses are 1 grams of amoxicillin, 40 mg of esomeprazole (Nexium), 500 mg of metronidazole and 250 mg of clarithromycin. Each drug will be given twice a day to be taken twice a day with the morning and evening meals. Subjects will receive one of three different combinations. The choice of which will be randomly chosen by the use of a computer program. The regimes are: all 4 drugs daily for 5 days, all 4 drugs daily for 10 days, and two drugs (esomeprazole and amoxicillin) for 5 days then all for drugs for 5 additional days.

Subjects will be asked to return within 4 days after completion of the treatment to evaluate how they did with the drugs. They will be asked bring back all unused medication and the bottles or containers that the medicine was packaged in. Your medication use and tolerance to the study drugs will be assessed. The treatment portion of the study will be complete at this point.

Evaluation of the effect of the treatment will take place 4-6 weeks after the end of therapy. Subjects will come back to the study site and will have a UBT or repeat endoscopy, if clinically indicated to verify that the Helicobacter pylori has been cured. Subjects will be asked not to take antibiotics or any other drugs that may affect the outcome of the breath test used to confirm that the treatment was successful.

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 2 Aug 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: one month after finishing study drugs). 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?

On the ClinicalTrials.gov record for NCT00656968, 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 30 Sep 2015; AzTrials last refreshed its copy on 7 Nov 2026.
