June 20, 2017 updated by: Takahisa Furuta, Hamamatsu University

Comparison of Rabeprazole and Esomperazole for the Eradication of H. Pylori (CREATION Study)

Patients infected with H. pylori are treated with rabeprazole 10 mg bid, AMPC 750 mg bid and CAM 200 mg bid or esomeprazole 20 mg bid, AMPC 750 mg bid and CAM 200 mg bid. Eradication rates are compared. Patients who have ever failed in eradication by CAM-based regimen are treated with rabeprazole 10 mg bid, AMPC 750 mg bid and MNZ 250 mg bid or esomeprazole 20 mg bid, AMPC 750 mg bid and MNZ 250 mg bid.

Detailed Description

Patients infected with H. pylori are treated with rabeprazole 10 mg bid, AMPC 750 mg bid and CAM 200 mg bid or esomeprazole 20 mg bid, AMPC 750 mg bid and CAM 200 mg bid. Eradication rates are compared. Patients who have ever failed in eradication by CAM-based regimen are treated with rabeprazole 10 mg bid, AMPC 750 mg bid and MNZ 250 mg bid or esomeprazole 20 mg bid, AMPC 750 mg bid and MNZ 250 mg bid. CYP2C19 genotypes and susceptibility to CAM are genetically measured. Other factors are also analyzed with reference to eradication rates.

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.

Active Comparator: rabeprazole group
rabeprazole-based regimen. This group is treated with rabeprazole 10 mg bid, AMPC 750 mg bid and CAM 200 mg bid for 1 week. Success or Failure of eradication of H. pylori is assessed by 13C-UBT 1 month after the treatment.
Drug: rabeprazole-based regimen
This group is treated with rabeprazole 10 mg bid, AMPC 750 mg bid and CAM 200 mg bid for 1 week. Success or Failure of eradication of H. pylori is assessed by 13C-UBT 1 month after the treatment.
Other Names:
  • RAC
Active Comparator: esomeprazole group
'esomeprazole^based regimen. This group is treated with esomeprazole 20 mg bid , AMPC 750 mg bid and CAM 200 mg bid for 1 week. Success or Failure of eradication of H. pylori is assessed by 13C-UBT 1 month after the treatment.
Drug: esomeprazole^based regimen

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

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
Eradication rates of H. pylori
Time Frame: At 4 weeks after treatment
Success or failure eradication of H. pylori was judged based on the 13C-urea breath test performed 1 month after the treatment.
At 4 weeks after treatment
influence of CYP2C19 genotypes on the eradication rates of H. pylori
Time Frame: At 4 weeks after treatment
influence of CYP2C19 genotypes on the eradication rates of H. pylori are analyzed. CYP2C19 genotypes are classified to the three groups, rapid metabolizer (RM), intermiediate metabolizer (IM) and Poor metabolizer (PM). Because esomperazole is metabolized by CYP2C19, the effects of esomeprazole is influenced by genotypes of CYP2C19. The eradication rates in RMs, IMs and PMs are compared.
At 4 weeks after treatment
Influences of susceptibility of H. pylori strains to clarithromycin (CAM) on the eradication rates of H. pylori
Time Frame: At 4 weeks after treatment
Influences of susceptibility to clarithromycin on eradication rates of H. pylori are analyzed.
At 4 weeks after treatment

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
