Study to Evaluate the Pharmacokinetics, Pharmacodynamics and Safety

March 25, 2013 updated by: Il-Yang Pharm. Co., Ltd.

A Phase 1, Randomized, Open-Label, Four-Period Crossover, Multiple-Dose, Single-Center Study to Evaluate the Pharmacokinetics, Pharmacodynamics and Safety Following Administration of Oral Doses of 10, 20 and 40 mg of Ilaprazole and 40 mg of Esomeprazole in Healthy Subjects

The objectives of this study were (a) to evaluate the pharmacokinetics and to evaluate and compare the pharmacodynamics of ilaprazole and esomeprazole following a single dose (Day 1) and once daily (QD) administration for 5 consecutive days each of 10-mg, 20-mg, and 40-mg ilaprazole tablets and 40-mg esomeprazole tablets; (b) to evaluate the safety of 10-mg, 20-mg, and 40-mg ilaprazole tablets following QD oral administration for 5 consecutive days; and (c) to characterize the plasma gastrin concentration profile on Day 1 and Day 5 following QD oral administration of 10-mg, 20-mg, and 40-mg ilaprazole and 40-mg esomeprazole tablets for 5 consecutive days.

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.

Ages Eligible for Study

14 years to 51 years (Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • 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.

Exclusion Criteria:

  • 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 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
Pharmacodynamics of mean pH and percentage of time pH
Time Frame: for 24 hours dosing of Ilaprazole
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.
for 24 hours dosing of Ilaprazole

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
ilaprazole and esomeprazole plasma concentration data and pharmacokinetic parameter estimates were tabulated and descriptive statistics computed
Time Frame: for 24 hours dosing of Ilaprazole
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
for 24 hours dosing of Ilaprazole
