• Have adenocarcinoma of the prostate
• Currently receiving continuous treatment with Gonadotropin-releasing hormone (GnRH) monotherapy for at least 6 months before or have undergone surgical removal of the testicles
• Serum testosterone of \< 50 ng/dL(\< 2.0 nM)
• Have rising PSA defined as a PSA of \>= 10 ng/mL obtained at screening or PSADT of ≤ 10 months with the first of the 3 consecutive PSA values used to calculate PSADT ≥ 2.0 ng/mL
• Have an Eastern Cooperative Oncology Group (ECOG) performance status less than or equal to 2
• Be capable of swallowing study agents whole as a tablet
• Be willing/able to adhere to the prohibitions and restrictions specified in this protocol
  • Major Exclusion Criteria:
• Have prior or current evidence of local disease progression or metastatic disease as defined by modified response evaluation criteria in solid tumors (RECIST) criteria
• Have received chemotherapy for treatment of castrate-resistant prostate cancer; however, if a patient received chemotherapy in an adjuvant setting, prior to having CRPC, for castrate-sensitive prostate cancer, the patient is still eligible
• Are currently receiving any antiandrogen therapy (eg, bicalutamide, flutamide, or nilutamide).
• If previously treated with antiandrogen therapy, there must be documentation of at least 2 consecutive rising PSA values at least 2 weeks apart obtained prior to screening
• If previously treated with flutamide, at least 1 of the PSA values must be obtained 4 weeks or more after flutamide discontinuation.
• If previously treated with bicalutamide or nilutamide, at least 1 of the PSA values must be obtained 6 weeks or more after antiandrogen discontinuation
• Have previously received agents having any CYP17 inhibitory activity for the treatment of prostate cancer, such as ketoconazole
• Have previously received aminoglutethimide
• Have an active infection or other medical condition that would contraindicate prednisone use
• Have uncontrolled hypertension

• Have received an investigational therapeutic within 30 days of screening
• Have partners of childbearing potential and are not willing to use a method of birth control with adequate barrier protection as determined to be acceptable by the principal investigator and sponsor during the study and for 1 week after last dose of abiraterone acetate.
• Individuals with a history of a non-prostate malignancy are ineligible for this study with the following exceptions. Individuals with a history of other malignancies are eligible if they have been disease-free for at least 3 years and are deemed by the investigator to be at low risk for recurrence of that malignancy. Individuals with the following cancers are eligible if diagnosed and treated within the past 3 years: basal cell or squamous cell carcinoma of the skin
