Trial summary

H pylori eradication failure with recommended triple therapy is mainly related to antibiotic resistance. However,IN VITRO culture of H pylori is uneasy and is not performed in routine practice. A molecular test of antibiotic resistance easy to perform is now available. Read more about this study

About this study

Official title: Medico-economic Evaluation of a Therapeutic Strategy Based on Molecular Detection of Antibiotic Resistance in the Management of H Pylori Infection

H pylori eradication failure with recommended triple therapy is mainly related to antibiotic resistance. However,IN VITRO culture of H pylori is uneasy and is not performed in routine practice. A molecular test of antibiotic resistance easy to perform is now available. The aim of the study was to compare eradication rates obtained with the standard treatment and with a treatment guided by the results of the molecular detection of antibiotic resistance.

Read the detailed description

At the present time, H pylori infection is treated with a standard triple therapy. Treatment of naïve patients with triple therapy ( PPI+amoxicillin+clarithromycin for 7 days) markedly decreased last years to reach 70% due to a clarithromycin resistance rate about 20% in France. In case of failure, the recommended second line treatment (PPI+amoxicillin+metronidazole for 14 days) gives a success rate of 60%. However, as culture is uneasy and is only possible in specialised labs sensitivity to antibiotics is not currently studied before treatment.

The aim of the study was to evaluate clinical and medico-economic benefit of the molecular detection of antibiotic resistance in order to guide the treatment.

The test is performed after DNA extraction from biopsy specimens taken at gastroscopy allowing rapid detection of H pylori and clarithromycin or quinolone resistance.

Patients with bacteriologically proven H pylori infection will be randomly allocated to either empirical usual treatment with PPI , amoxicillin 1g, clarithromycin 500 mg X 2 /day for 7 days in naïve patients and PPI, amoxicillin 1g,metronidazole 500 mg X 2 /day for 14 days in patients who failed a first line treatment , or to treatment guided by the molecular test: PPI , amoxicillin 1g, clarithromycin 500 mg X 2 /day for 7 days in case of sensitivity to clarithromycin.In case of resistance to clarithromycin, quinolone should be given and in case of resistance to quinolone clarithromycin should be given. In case of resistance to both antibiotics metronidazole should be given.

Eradication will be assessed by performing 4 weeks after the completion of treatment with Urea Breath Test.

What is being measured

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

  1. H. pylori eradication rate (at 3months according to the two strategies: empirical treatment versus treatment guided by molecular detection of antibiotic resistance)

    at 3 months according to the two strategies: empirical treatment versus treatment guided by molecular detection of antibiotic resistance

    Measured: at 3 months

Secondary outcomes (1)
  1. Comparative cost of the two strategies

    Measured: at 6 months according to the two strategies

Questions about this trial

What is this clinical trial studying?

A study testing Molecular detection of antibiotic resistance and standard triple therapy (PPI, amoxicillin, clarithromycin, metronidazole) in people with Helicobacter Pylori Infection, run by Assistance Publique - Hôpitaux de Paris at 1 site in France.

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 4 inclusion and 4 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 8 Nov 2013. 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 France. 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?

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?

H. pylori eradication rate (at 3months according to the two strategies: empirical treatment versus treatment guided by molecular detection of antibiotic resistance) (time frame: at 3 months). 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 NCT01168063, 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 8 Nov 2013.
