About this study

Official title: A Phase 1, Single Dose, Open-Label, Three-Period, Crossover Study to Determine the Effect of Food on the Pharmacokinetics of Abiraterone Acetate in Healthy Male Subjects

The purpose of this study is to determine the effect of food on the pharmacokinetics (how the drug concentrations change over time) of abiraterone acetate 1000 mg when administered as a single dose in healthy male volunteers.

Read the detailed description

This is an open-label (identity of assigned study drug will be known), randomized (treatment sequences will be assigned by chance) study of a single dose of abiraterone acetate 1000 mg administered orally (by mouth) in approximately 36 healthy male participants under fasted and fed conditions. Three doses of abiraterone acetate will be administered with a 7-day washout period between each dose. The total study duration for each participant will be 21 days. Participants will be randomized to one of six treatment sequences (ABC, ACB, BAC, BCA, CAB, CBA): Treatment A = abiraterone acetate 1000 mg administered after a high-fat meal; Treatment B = abiraterone acetate 1000 mg administered after a low-fat meal; Treatment C = abiraterone acetate 1000 mg administered in the fasted state. No food will be ingested for 4 hours post-dose. Participants will be confined at the clinical research unit from the day prior to dosing until clinic discharge on the day following dosing in each treatment period. Serial pharmacokinetic samples will be collected and safety will be monitored throughout the study.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Maximum observed concentration of abiraterone

    Measured: Within 1 hour prior to dose and 0.25, 0.5, 1, 1.5, 2, 3, 4, 6, 8, 12, 24, 48, 72, and 96 hours post-dose

  2. Time to maximum concentration of abiraterone

    Measured: Within 1 hour prior to dose and 0.25, 0.5, 1, 1.5, 2, 3, 4, 6, 8, 12, 24, 48, 72, and 96 hours post-dose

  3. Area under the concentration-time curve from time 0 to the last measurable concentration of abiraterone

    Measured: Within 1 hour prior to dose and 0.25, 0.5, 1, 1.5, 2, 3, 4, 6, 8, 12, 24, 48, 72, and 96 hours post-dose

  4. Area under the concentration-time curve extrapolated to infinity of abiraterone

    Measured: Within 1 hour prior to dose and 0.25, 0.5, 1, 1.5, 2, 3, 4, 6, 8, 12, 24, 48, 72, and 96 hours post-dose

  5. Apparent plasma terminal elimination rate constant of abiraterone

    Measured: Within 1 hour prior to dose and 0.25, 0.5, 1, 1.5, 2, 3, 4, 6, 8, 12, 24, 48, 72, and 96 hours post-dose

  6. Apparent terminal elimination half-life of abiraterone

    Measured: Within 1 hour prior to dose and 0.25, 0.5, 1, 1.5, 2, 3, 4, 6, 8, 12, 24, 48, 72, and 96 hours post-dose

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Treatment A: abiraterone acetate, Treatment B: abiraterone acetate and Treatment C: abiraterone acetate in people with Healthy Volunteers, run by Cougar Biotechnology, Inc..

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 22 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 26 Feb 2013. Status can change between updates, so confirm with the study contact before making plans.

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?

Maximum observed concentration of abiraterone (time frame: Within 1 hour prior to dose and 0.25, 0.5, 1, 1.5, 2, 3, 4, 6, 8, 12, 24, 48, 72, and 96 hours post-dose). The study lists 6 primary outcomes in all. 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 26 Feb 2013.
