Inclusion Criteria

All patients must fulfil the following criteria to participate in the study:
(1)Has provided written informed consent
(2)Histologically documented prostate cancer with evidence of metastatic disease on radiological evaluation, with or without symptoms (defined according to the brief pain inventory [BPI] scale, with use of analgesics or narcotics)
(3)Has received a first line docetaxel based chemotherapy (as a monotherapy) every 3 weeks schedule of administration with corticosteroids for a minimum of 6 cycles with a cumulative dose =360 mg/m2. Any combination with investigational or non investigational agent is prohibited
(4)Male aged =18 years old
(5)Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1
(6)Docetaxel-related adverse effects must have been resolved to NCI-CTCAE v4.03 Grade =1. Chemotherapy-induced alopecia and Grade 2 peripheral neuropathy are allowed
(7)No progressive disease at the end of docetaxel treatment defined according to RECIST criteria, no new lesion(s) assessed by bone scan and no elevated PSA for the three last tests with PSA3=PSA2=PSA1. The time between each PSA test should be preferably at least 14 days, however, a minimum of 7 days is acceptable.
Note: PSA value can be rounded to the nearest whole number if PSA>10 ng/mL. If the PSA3 value is above the PSA2, a fourth PSA test will be performed. The PSA4 value should be below or equal to PSA2.
(8)Last dose of docetaxel administered between 21 and 42 days before randomisation
(9)Chemical or surgical castration verified by levels of serum testosterone =50 ng/dL (1.75 nmol/L)
(10)A life expectancy of at least 12 weeks in the judgment of the Investigator
(11)The following laboratory values within 14 days prior to randomisation:
•Haematology
-Absolute granulocytes =1.5 x 109/L
-Platelets =100 x 109/L
-Haemoglobin =9 g/dL transfusions allowed, epoetin alfa allowed only if last administration >2 weeks before randomisation
•Biochemistry
-Bilirubin =1.5 x upper limit of normal (ULN)
-Serum creatinine =1.5 x ULN or calculated creatinine clearance (CrCl) using the Cockcroft-Gault formula =60 mL/min
-Alanine aminotransferase/ aspartate aminotransferase =3 x ULN (=5 x ULN if liver metastases present)
(12)If sexually active with partner of childbearing potential, patient will agree to use adequate contraceptive method (barrier contraceptive with spermicide) while receiving study treatment and until 14 days after the stop of study treatment or have been previously vasectomised
(13)Able to swallow and retain oral drug
(14)Able to adhere to the study visit schedule and other protocol requirements
(15)Must be available for treatment, evaluation assessments and follow-up at the study centres
(16)Able to comprehend the full nature and purpose of the study, including possible risks and side effects, and to cooperate with the Investigator and to comply with the requirements of the entire study.

Exclusion Criteria

A patient will not be included in the study if he:
(1)Has concurrent use of other anticancer agents or treatments, with the following exceptions: ongoing treatment with luteinising hormone-releasing hormone agonists or antagonists, denosumab or bisphosphonate (e.g. zoledronic acid) is permitted if started =4 weeks prior to Screening. Ongoing treatment should be kept at a stable dose regimen
(2)Has ongoing treatment with warfarin
(3)Had prior radiation therapy since starting docetaxel. Exceptions may be made for palliative non-myelosuppressive radiation therapy administered more than 2 weeks prior to randomisation

(5)Has ongoing treatment with corticosteroids at >10 mg/day prednisolone equivalent
(6)Has prostate cancer pain that warrants the initiation of radiotherapy or chemotherapy
(7)Has known hypersensitivity to the study treatment, to any of its excipients or treatments with a similar chemical structure
(8)Has ongoing treatment with cytochrome P450 (CYP) 1A2 or CYP3A4 metabolised drug substance with narrow therapeutic range at the start of study treatment
(9)Has a systemic exposure to ketoconazole or other strong CYP3A4 isozyme inhibitors or inducers within 14 days prior to the start of study treatment. Systemic exposure to amiodarone is not permitted within 1 year prior to the start of study treatment
(10)Has simultaneous participation in any other study involving treatment with investigational drugs or device or has received treatment with investigational drugs less than 4 weeks prior to randomisation
(11)Has myocardial infarction, percutaneous coronary intervention, acute coronary syndrome, coronary artery bypass graft, New York Heart Association (NYHA) class III/IV congestive heart failure, cerebrovascular accident, transient ischaemic attack, or limb claudication at rest, within 6 months prior to randomisation, has history of venous thrombo-embolic disease within 3 months prior to randomisation and ongoing symptomatic dysrhythmias, unstable angina, uncontrolled hypertension and uncontrolled atrial or ventricular arrhythmias
