- Ages 18 to 55 years
- All sexes
- Healthy volunteers accepted
- Adult
Who may be able to join
- Prior to any study-specific procedures being performed, the subject voluntarily signed the approved informed consent/PIPEDA authorization form after having it fully explained and all questions answered.
- The subject was between 18 and 55 years, inclusive, and was generally in good health.
- Pregnancy test results for all females were negative in order to enter and remain in the study. A serum pregnancy test was performed on all females at Screening, Day -1 of each period, and Day 6 of Period 4 only, or if a subject prematurely discontinued. Results must have been negative in order for study drug to be administered.
- Female subject was using, and agreed to continue the use of, a double-barrier method of birth control. Oral, patch, implants, or injectable contraceptives were accepted as 1 method if the subject had been taking them for greater than 2 months at the Screening Visit. Subjects who had a bilateral tubal ligation, hysterectomy, or bilateral oophorectomy for a minimum of 6 months, or surgical sterilization of partner (vasectomy for 6 months minimum), or were postmenopausal (defined as the absence of menses for 2 years or the absence of menses for 12 months and follicle-stimulating hormone [FSH] level of >40 IU/L) did not require the use of birth control.
- Subject had a negative breath test result for H pylori prior to enrollment.
- At the Screening Visit, subject had a body mass index (BMI) within the range of 18 to 30 kg/m2, as determined by the following calculation.
- Subject was in general good health as evidenced by a medical history, a complete physical examination, and ECG without clinically significant abnormalities.
Who cannot join
- Subject had current evidence of cardiovascular, central nervous system, hepatic, hematopoietic, renal, or metabolic dysfunction; serious allergy, asthma, history of significant sensitivity to any drug; or lactose intolerance that would contraindicate taking ilaprazole or esomeprazole or would interfere with the conduct of the study.

What is being measured
The primary outcome is the main question the study is designed to answer.
Pharmacodynamics of mean pH and percentage of time pH
For each regimen and day, mean pH and percentage of time pH exceeded 3, 4, 5, and 6 were tabulated and descriptive statistics were provided for 24-hour postdose intervals and each of the following intervals of time relative to dosing: 0 to 4 hours, >4 to 9 hours, >9 to 12 hours, >12 to 16 hours, and >16 to 24 hours.
Measured: for 24 hours dosing of Ilaprazole
Secondary outcomes (1)
ilaprazole and esomeprazole plasma concentration data and pharmacokinetic parameter estimates were tabulated and descriptive statistics computed
The assessments of dose proportionality for ilaprazole regimens were performed via 90% confidence intervals for the ratio of the central values obtained within the framework of the ANOVA on natural logarithms of dose-normalized Cmax, AUCt, and AUC
Measured: for 24 hours dosing of Ilaprazole

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Ilaprazole and Esomeprazole in people with Healthy and Pharmacokinetics, run by Il-Yang Pharm. Co., Ltd. at 1 site in Canada.
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 7 inclusion and 1 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 28 Mar 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 Canada. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
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?
Pharmacodynamics of mean pH and percentage of time pH (time frame: for 24 hours dosing of Ilaprazole). 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 28 Mar 2013.
