About this study

Official title: A Phase III Randomized Trial of Three Antibiotic Regimens to Eradicate Helicobacter Pylori

The purpose of this study is to compare the effectiveness of three different antibiotic regimens against Helicobacter pylori (H. pylori).

Read the detailed description

Prevention of gastric cancer through eradication of H. pylori is one of the most promising strategies to reduce the global impact of cancer in the near term. Our long-term goal is to prevent gastric cancer by developing and validating an effective, simple, and low-cost approach to eradication of H. pylori. Our immediate goal, therefore, is to conduct a randomized study to compare the effectiveness of three different drug regimens for H. pylori infection. The three study arms are: Standard therapy - 14 day, 3-drug regimen of Lansoprazole, amoxicillin and clarithromycin (PACx14); Concomitant therapy - 5 day, 4-drug regimen of lansoprazole, amoxicillin, clarithromycin, metronidazole (PACMx5); Sequential therapy - 10 day, 4-drug regimen of lansoprazole, amoxicillin for 5 days, followed by lansoprazole, clarithromycin and metronidazole for 5 days (PAx5/PCMx5).

What is being measured

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

  1. To compare 2 experimental antibiotic regimens with a standard 14 day regimen with regard to H. pylori eradication rates at 6 weeks post-randomization.

    Measured: week 6 post-randomization

Secondary outcomes (1)
  1. Secondary aims will examine infection rates at 1 year, safety and tolerability of these regimens,& potential differential effects among selected groups.

    Measured: 1 year

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing PACx14, PACMx5 and PAx5/PCMx5 in people with Helicobacter Pylori Infection, run by SWOG Cancer Research Network at 7 sites in 6 countries.

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 11 inclusion and 6 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 26 Sep 2012. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 7 sites in Mexico, Chile, Colombia, Costa Rica, Honduras and 1 more country. 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.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

To compare 2 experimental antibiotic regimens with a standard 14 day regimen with regard to H. pylori eradication rates at 6 weeks post-randomization. (time frame: week 6 post-randomization). 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 NCT01061437, which also lists 2 linked publications.

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 26 Sep 2012.
