April 18, 2013 updated by: Janssen Research & Development, LLC

An Expanded Access Open Label Study of CB7630 (Abiraterone Acetate) in Patients With Advanced Prostate Cancer Who Have Completed CB7630 Clinical Study COU-AA-001

The purpose of this study is to provide access to abiraterone acetate for patients who have completed 12 cycles of abiraterone acetate treatment in Clinical Study COU-AA-001 and continue to receive clinical benefit from this treatment.

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 an open-label (identity of study drug will be known) extended access study to evaluate the safety and efficacy of continued administration of abiraterone acetate in patients who have completed 12 cycles of abiraterone acetate treatment in Clinical Study COU-AA-001 and continue to receive clinical benefit from this treatment. Patients will continue with the same dose regimen administered at the end of Study COU-AA-001 and will receive a low-dose glucocorticoid daily. Patients will be followed every 3 months for disease progression and survival for up to 3 years following study entry. Safety will be monitored throughout the study up to 30 days after the last dose of study medication.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
54

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

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Male

Description

Inclusion Criteria:

  • Completed 12 cycles of abiraterone acetate under study COU-AA-001
  • Last dose of abiraterone acetate within 14 days prior to treatment in this study
  • Demonstrates potential to gain clinical benefit with continued abiraterone acetate treatment
  • Serum potassium level >=3.5 mmol/L
  • Eastern Cooperative Oncology Group Performance Status of <3 (Karnofsky Performance Status >=30%)
  • Agrees to protocol-defined use of effective contraception

Exclusion Criteria:

  • Serious or uncontrolled co-existent non-malignant disease, including active and uncontrolled infection
  • Uncontrolled hypertension
  • Abnormal liver function
  • Clinically significant heart disease as evidenced by a myocardial infarction in the past 12 months, severe or unstable angina, or New York Heart Association (NYHA) Class III or IV heart disease (patients with a history of atherosclerotic vascular disease requiring coronary or peripheral artery bypass surgery may be enrolled provided the surgery occurred at least 2 years prior to enrollment and after consultation with a cardiologist to insure that the disease is stable)
  • Condition or situation which, in the investigator's opinion, may put the patient at significant risk, may confound the study results, or may interfere significantly with 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
Time Frame
Number of participants with serum prostate specific antigen (PSA) decline according to PSA Working Group criteria
Time Frame: Screening, Cycle 1 Day 1 Pre-dose, every 3 months up to 3 years after study entry
Screening, Cycle 1 Day 1 Pre-dose, every 3 months up to 3 years after study entry
Overall survival
Time Frame: every 3 months up to 3 years after study entry
every 3 months up to 3 years after study entry

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
Time Frame
Number of participants with adverse events
Time Frame: up to 30 days after the last dose of study medication
up to 30 days after the last dose of study medication
Time to disease progression
Time Frame: every 3 months up to 3 years after study entry
every 3 months up to 3 years after study entry
Time to prostate specific antigen progression

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
