Clinical Details

Official title: A Phase 2 Open Label Study of Abiraterone Acetate (JNJ-212082) and Prednisolone in Patients With Advanced Prostate Cancer Who Have Failed Androgen Deprivation and Docetaxel-Based Chemotherapy.

Study design: Endpoint Classification: Safety/Efficacy Study, Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Treatment

Primary outcome: Prostate specific antigen (PSA) response rate

Secondary outcome:

Overall survival

Time to PSA progression

Objective radiographic response rate (RAD-ORR)

Serum testosterone and dehydroepiandrosterone (DHEA) sulfate

Number of patients with adverse events

Detailed description: This is an open-label (all people know the identity of the intervention), multicenter, single arm (only one treatment group) study to evaluate the efficacy and safety of abiraterone acetate in patients with mCRPC. The study will be divided into screening phase (up to 28 days before enrollment), treatment phase including treatment cycles (each cycle of treatment will be 28 days), and follow-up phase. Approximately 80 patients will be enrolled into this study. Safety evaluations for adverse events, clinical laboratory tests, electrocardiogram and vital signs as well as pharmacokinetic (what the body does to drug) assessments will be conducted in this study. Patients will continue to receive abiraterone acetate plus prednisolone until disease progression or occurrence of unacceptable toxicity.


Minimum age: 18 Years. Maximum age: N/A. Gender(s): Male.
