About this study

Official title: Prospective Randomized Trial: Comparison Between Optimized-dose Amoxicillin and Standard-dose Amoxicillin for Quadruple Therapy in the Treatment of Helicobacter Pylori Infection in Tunisian Patients

The goal of this prospective randomized clinical trial is to compare the rate of Helicobacter Pylori (HP) eradication after standard or dose-optimized amoxicillin quadritherapy in patients naïve to any anti-HP treatment and with chronic HP infection documented by histological examination. The main questions it aims to answer are:

  • compare the eradication rate of H.Pylori after a standard concomitant quadritherapy with 2g of amoxicillin versus an optimized quadritherapy with 3g of amoxicillin, in Tunisian population
  • Identify different factors associated with poor therapeutic response Patients were randomly assigned to either standard quadruple therapy (Qs-14: amoxicillin 1g twice daily, clarithromycin 500mg twice daily, metronidazole 500mg twice daily and esomeprazole 40mg twice daily for 14 days), or optimized quadruple therapy (Qo-14: amoxicillin 1g three times a day, clarithromycin 500mg twice daily, metronidazole 500mg twice daily and esomeprazole 40mg twice daily for 14 days). Eradication control was performed by urea breath test.
Read the detailed description

This study was a prospective, randomized, single-center study conducted in the hepato-gastroenterology department of Mahmoud Matri Hospital in Ariana, in collaboration with the bacteriology and biochemistry laboratory of the same hospital, the anatomopathology department of Abderrahmen Mami Hospital in Ariana, and the private clinical analysis laboratory "Fendri". all patients aged from 18 and 65 years-old with H. pylori infection documented by pathological examination of per endoscopic gastric biopsies were recruited.

This was a population of patients who had undergone upper endoscopy (UE) and in whom the search for H.Pylori was indicated, according to the European Maastrich IV recommendations.

Eligible subjects were randomly assigned in a 1:1 ratio to receive either standard quadruple therapy (Qs-14) including : amoxicillin 1g twice daily ,clarithromycin 500mg twice daily ,metronidazole 500mg twice daily and esomeprazole (Medis Pharmaceutical Company) 40 mg twice daily for 14 days, or optimized quadruple therapy (Qo-14) including : amoxicillin 1g three times daily ,clarithromycin 500mg twice daily, metronidazole 500mg twice daily and esomeprazole 40 mg twice daily (Medis Pharmaceutical Company) for 14 days.

Eradication control was performed by 13C-UBT at least 4 weeks after the end of the treatment.

What participants receive

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

  • optimized quadruple therapyDrug

    Also called Qo-14

    Association of amoxicillin 3 g/day + Esomeprazole, nitroimidazole and clarithromycin for 14 days

  • standard quadruple therapyDrug

    Also called Qs-14

    Association of amoxicillin 2 g/day + Esomeprazole, nitroimidazole and clarithromycin for 14 days

Study groupRoleWhat they receive
optimized quadruple therapy (Qo-14)Experimentalpatients allocated to experimental group receive an optimized quadruple therapy (Qo-14) including 3 grams of Amoxicillin plus standard dose of clarithromycin, metronidazole and esomeprazole for 14 days.
Receives: Drug: optimized quadruple therapy
standard quadruple therapy (Qs-14)Active comparatorpatients allocated to this group receive standard quadruple therapy (Qs-14) including : amoxicillin 1g twice daily ,clarithromycin 500mg twice daily ,metronidazole 500mg twice daily and esomeprazole 40 mg twice daily for 14 days
Receives: Drug: standard quadruple therapy

What is being measured

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

  1. HP eeradication rate

    Urea Breath test (UBT) is performed no sooner than 6 weeks after completion of H pylori therapy. Use of PPIs should be discontinued for at least 2 weeks before administration of the UBT.

    Measured: 6 weeks after treatment completion

Secondary outcomes (1)
  1. prevalence of adverse reactions

    The percentage of patients reporting side effects during treatment and the following days until the evaluation of Hp eradication

    Measured: 6 weeks after treatment completion

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing optimized quadruple therapy and standard quadruple therapy in people with Helicobacter Pylori, run by Les Laboratoires des Médicaments Stériles at 1 site in Tunisia.

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 7 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 2 Dec 2022. 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 Tunisia. 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 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?

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?

HP eeradication rate (time frame: 6 weeks after treatment completion). 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 2 Dec 2022.
