About this study

Official title: A Phase 1 Single Dose Open-Label Reduced/Staged Pharmacokinetic Study of Abiraterone Acetate in Male Subjects With Impaired Renal Function Compared to Matched Control Subjects With Normal Renal Function

The purpose of this study is to determine the pharmacokinetic (how the drug concentrations change over time) profile of abiraterone acetate 1000 mg when administered as a single dose in male participants with impaired renal function compared to individuals with normal renal function.

Read the detailed description

This is an open-label (identity of assigned study drug will be known) pharmacokinetics study evaluating a single dose of abiraterone acetate 1000 mg administered in male participants with end-stage renal disease compared to matched-control (matched for age and body mass index) participants with normal renal function. There will be approximately 8 participants in each cohort (group). The total study duration for each participant will be 36 days. Abiraterone acetate 1000 mg will be administered orally (by mouth) as a single dose in the fasted state on Day 1. No food will be ingested for 4 hours post-dose. Participants will be confined to the clinical research center from the day prior to dosing (Day -1) to Day 5 and will return to the clinic on Days 8, 15, and 22 for follow up. Serial pharmacokinetic samples will be collected and safety will be monitored throughout the study.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Abiraterone acetate: participants with end-stage renal disease in people with Renal Insufficiency, run by Cougar Biotechnology, Inc. at 1 site in United States.

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 13 inclusion and 19 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 19 Nov 2012. 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 United States. 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?

Maximum observed plasma concentration of abiraterone (time frame: Within 0.5 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 8 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01715259, which also lists 1 linked publication.

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 19 Nov 2012.
