A Study That Provides Long-term Safety Follow-up and Examines Long-term Exposure to Abiraterone Acetate

April 20, 2022 updated by: Janssen Research & Development, LLC

A Phase 3b Multicenter, Open-label Abiraterone Acetate Long-term Safety Study

The purpose of this study is to collect follow-up safety data from participants in completed abiraterone acetate studies for a maximum duration of 9 years.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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 nonrandomized (individuals will not be assigned by chance to study treatments), open-label (individuals will know the identity of study treatments), long-term safety follow-up study of abiraterone acetate in approximately 300 patients from other completed abiraterone acetate clinical studies. Patients must have received at least 3 months of treatment with abiraterone acetate and a low-dose corticosteroid and, based on investigator assessment, may benefit from continued treatment. This study will consist of a screening period followed by open-label treatment of continued abiraterone acetate access. The patients will continue with the same abiraterone acetate and low-dose corticosteroid dosing regimen they were receiving in the previous abiraterone acetate clinical study until the investigator determines that the patient is no longer receiving benefit or the sponsor terminates the study. Patients can be withdrawn from the study if an alternative access (eg, patient-assistance program or commercial source of abiraterone acetate) is available and feasible. Each cycle of treatment will be 28 days. Investigators will monitor and assess the patients for response to treatment or progression according to routine practice or as clinically indicated to determine whether continued treatment with abiraterone acetate is warranted. No efficacy data are being collected. Safety will be monitored throughout the study for a maximum duration of 9 years. End-of-study assessments will be performed at least 30 days after the last dose of abiraterone or upon early withdrawal.

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

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Currently participating in an abiraterone acetate clinical study considered complete and had received at least 3 months of treatment with abiraterone acetate tablets.

Exclusion Criteria:

  • Medical conditions that require hospitalization.
  • Any condition or situation which, in the opinion of the investigator, may put the patient at significant risk, may confound the study results, or may interfere significantly with the patient's participation in 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
Number of Participants With Serious Adverse Events (SAEs)
Time Frame: Up to 9 years
An SAE is defined as any untoward medical occurrence that results in death, is life-threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, leads to a congenital anomaly/birth defect in the offspring of a participant, or is an important medical event.
Up to 9 years
