December 16, 2015 updated by: Xiwei Xu, Beijing Children's Hospital

Tailored Therapy Versus Standard Triple Therapy for Helicobacter Pylori Eradication in Children: A Randomized Trial

This study is designed to compare the eradication rates，safety and compliance of tailored therapy to those of standard triple therapy in children with H. pylori infection. The primary purpose is to compare the eradication rates of children with H. pylori infection treated with tailored therapy to those treated with standard triple therapy. The secondary purpose is to evaluate the safety, compliance and factors that might affect eradication rates.

Detailed Description

Between March 2014 and March 2016, 200 children with upper gastrointestinal symptoms (4-18 years) and H. pylori infection will be recruited at Beijing Children Hospital.After the informed consents are obtained from the guardians, the children will be randomly classified into the two group: 10 days standard triple therapy (Omeprazole 0.8-1.0mg/kg.d,bid, Amoxicillin 30-50mg/kg.d bid， Clarithromycin 15-20mg/kg.d bid), or 10 days tailored therapy including one Proton Pump Inhibitor ( Rabeprazole 0.4-0.5mg/kg.d,bid. or Esomeprazole 0.8-1.0mg/kg.d,bid) and two antibiotics (Amoxicillin 30-50mg/kg.d bid, Clarithromycin 15-20mg/kg.d bid, Metronidazole15-20mg/kg.d bid) based on antibiotics susceptibility and cytochrome P450 isoenzyme 2C19 genotype. Eradication status will be reassessed in four weeks after treatment.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Experimental: Tailored Group
In tailored therapy, medications will be adjusted according to the antimicrobial susceptibility testing (including Clarithromycin sensitivity) and cytochrome P450 isoenzyme 2C19 genotype. 10 days regimen will be prescribed.
Drug: Tailored Group
All the patients who enrolled in this arm will be received endoscopy followed by biopsy for antimicrobial susceptibility testing and cytochrome P450 isoenzyme 2C19 genotype. 10 days tailored therapy will be given including one Proton Pump Inhibitor ( Rabeprazole0.4-0.5mg/kg.d,bid. or Esomeprazole0.8-1.0mg/kg.d,bid) and two antibiotics (Amoxicillin30-50mg/kg.d bid, Clarithromycin15-20mg/kg.d bid, Metronidazole15-20mg/kg.d bid ) based on the cytochrome P450 isoenzyme 2C19 genotype and the antimicrobial susceptibility.

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Compare the eradication rates in each group
Time Frame: One month after treatment
The efficacy of H. pylori eradication between the standard triple therapy and tailored therapy based on the results of antimicrobial resistance(including Clarithromycin sensitivity) by using H. pylori culture and cytochrome P450 isoenzyme 2C19 genotype. Eradication status will be reassessed in one month after treatment.
One month after treatment

Other Outcome Measures
