About this study

Official title: 10-Day Antimicrobial Susceptibility Testing Guided Triple Therapy Versus 14-Day Empirical Tailored Therapy for the First-line Treatment of Helicobacter Pylori Infection-A Randomized Controlled Trail

The purpose of this study is to assess efficacy of 10-day antimicrobial susceptibility test guided triple therapy for the first-line treatment of Helicobacter pylori infection, then comparing it with 14-day empirical tailored therapy to tell which one has a better performance in both efficacy and safety.

Read the detailed description

Helicobacter pylori(H.pylori), which infects about 50% of the global population, has been recognized as a main risk factor of multiple gastric pathologies, especially non-cardiac gastric cancer. Strongly evidence supports that H.pylori eradication is an effective approach to reduce the incidence of those pathologies. Antimicrobial susceptibility test can pick out sensitive drugs to kill Helicobacter pylori, and reduce secondary drug resistance. But, there is a lack of high quality RCT to compare its efficacy with empirical regimen in the first-line treatment.

Our study aims to assess the efficacy of 10-day antimicrobial susceptibility test guided triple therapy for the first-line treatment of Helicobacter pylori infection. Comparing this regimen with 14-day Empirical Tailored Therapy to tell which one is better in clinic practice. We also want to find whether the 10-day antimicrobial susceptibility test guided triple therapy has less intestinal dysbacteriosis with a shorter duration.

Being tested
two sensitive antibiotics(amoxicillin, clarithromycin, metronidazole, tinidazole, levofloxacin, furazolidone and tetracycline), two antibiotics based on personal medication history(amoxicillin,clarithromycin,furazolidone), one proton pump inhibitor(PPI), Colloidal Bismuth Pectin, two antibiotics for failed eradication(tetracyclin,furazolidone)
Keywords
Helicobacter Pylori Infection, Antimicrobial Susceptibility testing(AST)

What participants receive

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

  • two sensitive antibiotics(amoxicillin, clarithromycin, metronidazole, tinidazole, levofloxacin, furazolidone and tetracycline)Drug

    Patients will receive a 10-day triple therapy for the H.pylori eradication. The regimen contains one PPI and two sensitive antibiotics determined by AST. The susceptibility of amoxicillin, clarithromycin, metronidazole, tinidazole, levofloxacin, furazolidone and tetracycline will be evaluated.

  • two antibiotics based on personal medication history(amoxicillin,clarithromycin,furazolidone)Drug

    Patients will receive a 14-day bismuth-based quadruple therapy for the H.pylori eradication. The regimen contains one PPI, Colloidal Bismuth Pectin and two antibiotics based on personal medication history. If the patient has taken clarithromycin, roxithromycin and azithromycin for less than 2 weeks before, he will be treated with amoxicillin and clarithromycin. Otherwise, he will be treated with amoxicillin and furazolidone.

  • one proton pump inhibitor(PPI)Drug

    All the patients need this drug.

  • Colloidal Bismuth PectinDrug

    All the patients treated with 14-day bismuth-based quadruple therapy need this drug.

  • two antibiotics for failed eradication(tetracyclin,furazolidone)Drug

    If the patients failed with AST guided eradication therapy or empirical therapy, patients will be treated with another 14-day bismuth-based quadruple therapy. The regimen contains one PPI, Colloidal Bismuth Pectin, tetracycline and furazolidone.

What is being measured

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

  1. Eradication rates in 2 groups

    Both intention to treat(ITT) and per-protocol(PP) analyses will be used for the assessment of the eradication rates of Helicobacter pylori infections in two groups. The ITT analysis includes all randomly assigned patients who take at least one dose of the study medications. The PP analysis is limited to patients who take over 90% of the study medications and complete follow-up.

    Measured: 6 months

Secondary outcomes (4)
  1. The rate of improving dyspepsia symptoms after Helicobacter pylori eradication.

    Dyspepsia symptoms will be measured using a 8-point Likert scale, and patients rate their symptoms from 0 (none) to 8 (severe) before and after the Helicobacter pylori eradication.

    Measured: 6 months

  2. The rate of adverse events happening

    Similarly, adverse events will also be measured by the Likert scale.

    Measured: 6 months

  3. The rate of good compliance

    Patients taken over 90% of drugs are considered to have a good compliance.

    Measured: 6 months

  4. Difference of cost per patient for each eradication achieved in two groups

    Measured: 6 months

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: status not confirmed, as of the sponsor's last update on 27 Jun 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

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?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Xiuli Zuo, PhD,MD (15588818685 ext. 053188369277, zuoxiuli@sina.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Eradication rates in 2 groups (time frame: 6 months). 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 27 Jun 2018.
