•- Histologically confirmed adenocarcinoma of the prostate
•- Male subjects of age = 18 years. The lower limit may be higher if legally required in the participating country
•- Prostate cancer progression documented by prostate specific antigen according to the Prostate Cancer Working Group 2 (PCWG2) criteria or radiological progression according to Response Evaluation Criteria in Solid Tumors (RECIST), version 1.1.
•- Two or more bone metastases on bone scan within 4 weeks prior to randomization with no lung, liver, other visceral and/or brain metastasis.
•- Asymptomatic or mildly symptomatic prostate cancer.
•- Subjects who received combined androgen blockade with an anti-androgen must have shown PSA progression after discontinuing the anti-androgen prior to enrollment.
•- Maintenance of medical castration3 or surgical castration with testosterone less than 50 ng/dL (1.7 nmol/L). If the subject is being treated with luteinizing hormonereleasing hormone (LHRH) agonists or antagonists (subject who has not undergone orchiectomy), this therapy must have been initiated at least 4 weeks prior to randomization and must be continued throughout the study.
•- Eastern Cooperative Oncology Group (ECOG) Performance Status 0 or 1
•Are the trial subjects under 18? no
•Number of subjects for this age range:
•F.1.2 Adults (18-64 years) yes
•F.1.2.1 Number of subjects for this age range 600
•F.1.3 Elderly (>=65 years) yes
•F.1.3.1 Number of subjects for this age range 200

•- Prior cytotoxic chemotherapy for the treatment of CRPC, including taxanes, mitoxantrone and estramustine
•- Administration of immunotherapies (e.g., sipuleucel-T) within 4 weeks before randomization
•- Any chronic medical condition requiring a higher dose of corticosteroid than 5 mg prednisone/prednisolone twice daily.
•- Pathological finding consistent with small cell carcinoma of the prostate
•- History of visceral metastasis, or presence of visceral metastasis detected by screening imaging examinations
•- History of or known brain metastasis.
•- Malignant lymphadenopathy exceeding 3 cm in shortaxis diameter.
•- Blood transfusion or erythropoietin stimulating agents prior 4 weeks of screening and during the whole screening period before randomization
•- Imminent spinal cord compression based on clinical findings and/or magnetic resonance imaging (MRI).
•Subjects with history of spinal cord compression should have completely recovered
•- Use of opiate analgesics for cancer-related pain, including codeine and dextropropoxyphene, currently or
•anytime during the 4- week period prior to randomization.
