Title: A Phase 3, Randomized, Double-blind, Placebo-Controlled Study of Abiraterone Acetate (CB7630) Plus Prednisone in Asymptomatic or Mildly Symptomatic Patients With Metastatic Castration-Resistant Prostate Cancer
Brief Summary: This is a phase 3 study to compare the clinical benefit of abiraterone acetate plus prednisone with placebo plus prednisone in asymptomatic or mildly symptomatic patients with metastatic castration-resistant prostate cancer (CRPC).


Options:
A: Inclusion Criteria

1. Histologically or cytologically confirmed adenocarcinoma of the prostate that is refractory to hormone therapy and previously treated with a Taxotere®-containing regimen.
2. Documented progression of disease (demonstrating at least one visceral or soft tissue metastatic lesion, including a new lesion). Patients with non-measurable disease must have documented rising prostate-specific antigen (PSA) levels or appearance of new lesion.
3. Surgical or hormone-induced castration
4. Life expectancy \> 2 months
5. Eastern Cooperative Oncology Group (ECOG) performance status 0 - 2

Exclusion criteria

1. Previous treatment with mitoxantrone
2. Previous treatment with \<225 mg/m\^2 cumulative dose of Taxotere (or docetaxel)
3. Prior radiotherapy to ≥ 40% of bone marrow
4. Surgery, radiation, chemotherapy, or other anti-cancer therapy within 4 weeks prior to enrollment in the study
5. Other prior malignancy, except for adequately treated superficial basal cell skin cancer, or any other cancer from which the patient has been disease-free for less than 5 years
6. Known brain or leptomeningeal involvement
7. Other concurrent serious illness or medical conditions
8. Inadequate organ function evidenced by unacceptable laboratory results

The investigator will evaluate whether there are other reasons why a patient may not participate.
B: Inclusion Criteria:

* Metastatic castration-resistant prostate cancer (CRPC)
* Previous anti-androgen therapy and progression after withdrawal
* ECOG performance status of either 0 or 1
* Medical or surgical castration with testosterone less than 50 ng/dL
* Life expectancy of at least 6 months

Exclusion Criteria:

* Prior cytotoxic chemotherapy or biologic therapy for CRPC
* Prior ketoconazole for prostate cancer
* Known brain metastasis or visceral organ metastasis
* Use of opiate analgesics for cancer-related pain, including codeine and dextropropoxyphene, currently or anytime within 4 weeks of Cycle 1 Day 1
C: To qualify for this trial, you must have ALL of the following:

* Histologically documented adenocarcinoma of the prostate
* Cancer that has progressed while on adequate hormone therapy. This state of the disease is androgen independent prostate cancer (AIPC).
* Cancer that has spread outside the prostate (metastatic) to lymph nodes or bone. Please note that if your cancer has spread to organs (e.g., liver, lung, brain), you are not eligible for the study.
* The absence of or minimal current cancer-related pain

Please note that there are additional eligibility criteria. The study center will determine if you meet all of the criteria.

Study personnel will explain the trial in detail and answer any questions you may have if you do qualify for the study. You can then decide whether or not you wish to participate. If you do not qualify for the trial, study personnel will explain the reasons.
D: Men starting first line androgen deprivation therapy for metastatic prostate cancer.

Inclusion criteria:

1. Male aged 18 or older with metastatic adenocarcinoma of the prostate
2. Target or non-target lesions according to Response Evaluation Criteria in Solid Tumours (RECIST) 1.1
3. Adequate bone marrow function: Haemoglobin (Hb) ≥100g/L and White Cell Count (WCC) ≥ 4.0 x 109/L and platelets ≥100 x 109/L.
4. Adequate liver function: Alanine transaminase (ALT) \< 2 x Upper Limit of Normal (ULN) and bilirubin \< 1.5 x ULN, (or if bilirubin is between 1.5-2 x ULN, they must have a normal conjugated bilirubin). If liver metastases are present ALT must be \< 5 x ULN
5. Adequate renal function: calculated creatinine clearance \> 30 ml/min (Cockcroft-Gault)
6. Eastern Cooperative Oncology Group (ECOG) performance status of 0-2. Patients with performance status 2 are only eligible if the decline in performance status is due to metastatic prostate cancer.
7. Study treatment both planned and able to start within 7 days after randomisation.
8. Willing and able to comply with all study requirements, including treatment and required assessments
9. Has completed baseline Health-Related Quality of Life (HRQL) questionnaires UNLESS is unable to complete because of limited literacy or vision
10. Signed, written, informed consent

Exclusion Criteria:

1. Prostate cancer with significant sarcomatoid or spindle cell or neuroendocrine small cell components
2. History of

   * seizure or any condition that may predispose to seizure (e.g., prior cortical stroke or significant brain trauma).
   * loss of consciousness or transient ischemic attack within 12 months of randomization
   * significant cardiovascular disease within the last 3 months including: myocardial infarction, unstable angina, congestive heart failure, ongoing arrhythmias of Grade \>2 \[National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE), version 4.03\], thromboembolic events (e.g., deep vein thrombosis, pulmonary embolism). Chronic stable atrial fibrillation on stable anticoagulant therapy is allowed.
3. Life expectancy of less than 12 months.
4. History of another malignancy within 5 years prior to randomisation, except for either non- melanomatous carcinoma of the skin or, adequately treated, non-muscle-invasive urothelial carcinoma of the bladder (Tis, Ta and low grade T1 tumours).
5. Concurrent illness, including severe infection that might jeopardize the ability of the patient to undergo the procedures outlined in this protocol with reasonable safety

   a. Human Immunodeficiency Virus (HIV)-infection is not an exclusion criterion if it is controlled with anti-retroviral drugs that are unaffected by concomitant enzalutamide.
6. Presence of any psychological, familial, sociological or geographical condition potentially hampering compliance with the study protocol and follow-up schedule, including alcohol dependence or drug abuse;
7. Patients who are sexually active and not willing/able to use medically acceptable forms of barrier contraception.
8. Prior ADT for prostate cancer (including bilateral orchidectomy), except in the following settings:

   * Started less than 12 weeks prior to randomisation AND Prostate Specific Antigen (PSA) is stable or falling. The 12 weeks starts from whichever of the following occurs earliest: first dose of oral anti- androgen, LHRHA, or surgical castration.
   * In the adjuvant setting, where the completion of adjuvant hormonal therapy was more than 12 months prior to randomisation AND the total duration of hormonal treatment did not exceed 24 months. For depot preparations, hormonal therapy is deemed to have started with the first dose and to have been completed when the next dose would otherwise have been due, e.g. 12 weeks after the last dose of depot goserelin 10.8mg.
9. Prior cytotoxic chemotherapy for prostate cancer, but up to 2 cycles of docetaxel chemotherapy for metastatic disease is permitted.
10. Participation in other clinical trials of investigational agents for the treatment of prostate cancer or other diseases.
