A Pharmacokinetic and Relative Bioavailability Study With Rabeprazole Sodium in Healthy Adult Volunteers

May 26, 2014 updated by: Johnson & Johnson Pharmaceutical Research & Development, L.L.C.

A Phase 1, Open-Label, Randomized, Crossover Study to Assess the Relative Bioavailability of Rabeprazole Phase 3 Pediatric Bead Formulation Versus the Phase 1 Pediatric Bead Formulation and Effect of Food on the Pharmacokinetics of Rabeprazole Phase 3 Pediatric Bead Formulation in Healthy Subjects

The purpose of the study is to evaluate and compare the pharmacokinetics (blood levels) of 2 different formulations, assess the effect of food on the pharmacokinetics and assess safety of rabeprazole sodium in healthy volunteers. Rabeprazole sodium is a drug used to treat patients with Gastro Esophageal Reflux Disease (GERD). GERD is a condition in which the esophagus (tube from throat to stomach) becomes irritated or inflamed because of acid backing up from the stomach.

Detailed Description

This is a randomized (study drug assigned by chance), open-label (the patient knows the treatment/drug they are taking), single-dose, 3-way crossover study to evaluate and compare the pharmacokinetics (blood levels) and safety of 2 formulations of orally (by mouth) administered rabeprazole sodium in healthy volunteers. Rabeprazole sodium is a drug used to treat patients with Gastro Esophageal Reflux Disease (GERD), a condition in which the esophagus (tube from throat to stomach) becomes irritated or inflamed because of acid backing up from the stomach. The primary outcome measure of the study is to evaluate the relative bioavailability (the rate and extent at which the drug is absorbed and reaches blood circulation ) of rabeprazole sodium (Phase 3 versus Phase 1 formulation) and the effect of food (Phase 3 formulation) by estimation of standard plasma PK parameters (Cmax, the maximum concentration of the drug in the blood observed after its administration; tmax, the time it takes for the drug to reach its maximum concentration in the blood after its administration; and AUC [the area under the curve]) of rabeprazole and its major metabolite.Blood samples to assess the PK of study drugs will be obtained before and up to 16 hours after dosing on Day 1 during 3 treatment periods. Thirty-six (36) healthy volunteers will be enrolled and will participate in the study for a total of approximately 36 days (from beginning of screening until the end-of-study procedures). During the study, the healthy volunteer will make a total of approximately 4 visits to the study center. The 4 visits will include a screening visit and three 2-day inpatient stays to receive study drug. During the screening visit, the details regarding the study will be explained and if the volunteer wishes to participate in the study, a signed informed consent form will be obtained. After informed consent is obtained, study specific entry criteria will be reviewed with the volunteer, information regarding the volunteer's medical history and demographics (age, race, etc) will be collected, and the following procedures will be performed: physical examination, measurement of vital signs (pulse rate and blood pressure), 12-lead electrocardiogram (ECG), serum pregnancy test (for women of childbearing potential), serology, drug screen and alcohol test, and laboratory testing (hematology, serum chemistry, and urinalysis). During each treatment period, volunteers who fulfill study enty criteria will be randomized to receive 1 of 3 treatments as follows: (1) a strawberry flavored suspension of the phase 1 formulation of study drug in a fasted state (2) a strawberry flavored suspension of the phase 3 formulation of study drug in a fasted state , and (3) a strawberry flavored suspension of the phase 3 formulation of study drug in a fed state (with food) OR phase 3 formulation of study drug sprinkled on 1 ounce of plain yogurt. During each 2-day treatment period, volunteers will be admitted to the study center after an overnight fasting (withholding consumption of food) period of at least 8 hours before blood is drawn for laboratory safety testing on Day 1, receive study drug on Day 1, and remain overnight at the study center unit for completion of all Day 2 study procedures. After all Day 2 study procedures are completed, the volunteer will be discharged from the study center unit for a 7- to 14-day period and then return to the study center for the 2nd treatment period. The same procedures will be followed for treatment periods 2 and 3. During the study, safety will be monitored by the measurement of vital signs before and after dosing during each treatment period, ECG findings at screening and at the end-of-study (Day 2 of treatment period 3 or at the time of early withdrawal from the study), and the evaluation of adverse events reported from the time of screening through to the end of the study. In each of 3 treatment periods, healthy volunteers will receive the equivalent of a 10 mg dose of rabeprazole sodium (ie, four 2.5 mg capsules of the phase 3 pediatric bead formulation or two 5-mg sachets of the phase 1 pediatric bead formulation) mixed with a strawberry-flavored vehicle and administered orally as a suspension or they will receive four 2.5 mg capsules of the phase 3 formulation sprinkled on plain yogurt to be ingested (eaten).

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.
