Bioequivalence Study of Abiraterone Acetate Coated and Uncoated Tablet Formulations in Healthy Male Participants

January 18, 2016 updated by: Janssen Research & Development, LLC

A Single-Dose, Open-Label, Randomized, 3-Way Crossover Pivotal Study to Assess the Bioequivalence of 2 Abiraterone Acetate Coated Tablet Formulations With Respect to the Current Commercial Abiraterone Acetate Uncoated Tablet Formulation Under Fasted Conditions in Healthy Male Subjects

The purpose of this study is to determine the bioequivalence (equivalence of pharmacokinetic parameters) of 2 abiraterone acetate coated tablet formulations with respect to the current commercial abiraterone acetate uncoated tablet formulation under fasted (without eating or drinking) conditions in healthy male participants.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This is a Phase 1, randomized (study medication assigned to participants by chance), open-label (all people know the identity of the intervention), single-center, single-dose and 3-way Crossover (the same medications provided to all participants but in different sequence) pivotal study to determine the bioequivalence of 2 abiraterone acetate coated tablet formulations with respect to the current commercial abiraterone acetate uncoated tablet formulation. Approximately 102 healthy male participants will participate in this study. Participants will be randomly assigned to 1 of 6 treatment sequences. The study will consist of 3 parts: Screening Phase (within 21 days before the first study drug administration of the first period), an open-label treatment Phase consisting of 3 single-dose treatment periods (45 days) and follow-up Phase (5 to 7 days after the last study procedure). The total study duration for each participant will be from 45 days to a maximum of 61 days. Participants will receive a single oral 1000 milligram (mg) dose of abiraterone acetate under fasted conditions either as Treatment A (current commercial formulation, uncoated), Treatment B (current commercial formulation, coated) or Treatment C (new composition, coated). Bioequivalence will be primarily evaluated by pharmacokinetic parameters. Participants' safety will be monitored throughout 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

The AUC (0-infinity) is the area under the plasma abiraterone acetate concentration-time curve from time 0 to infinite time, calculated as the sum of AUC (0-last) and C(last)/lambda(z), in which AUC(0-last) is area under the plasma abiraterone acetate concentration-time curve from time zero to time of the last quantifiable concentration, C(last) is the last observed quantifiable concentration and lambda(z) is elimination rate constant.
Pre-dose; 0.25, 0.5, 1, 1.5, 2, 3, 4, 6, 8, 12, 24, 48, 72 and 96 hours post-dose on Day 1 of each period

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
Time to Reach the Maximum Plasma Concentration (Tmax) of abiraterone acetate
Time Frame: Pre-dose; 0.25, 0.5, 1, 1.5, 2, 3, 4, 6, 8, 12, 24, 48, 72 and 96 hours post-dose on Day 1 of each period

Percentage of area under the plasma abiraterone acetate concentration-time curve extrapolated from last measurable concentration to infinite time (%AUC, ext) is calculated using formula: ((AUC [0-infinity] minus- AUC [0-last)]/AUC [0-infinity])*100.
Pre-dose; 0.25, 0.5, 1, 1.5, 2, 3, 4, 6, 8, 12, 24, 48, 72 and 96 hours post-dose on Day 1 of each period

Time Frame: Screening up to follow-up (5 to 7 days after last dose administration)
An adverse event (AE) is any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. A serious adverse event (SAE) is an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly.
Screening up to follow-up (5 to 7 days after last dose administration)
