*Subjects must have signed an informed consent document indicating that they understand the purpose of and procedures required for the study and are willing to participate in the study.
*Written Authorization for Use and Release of Health and Research Study Information (United States [U.S.] sites only) or Data Protection Consent (European sites only) has been obtained.
* Subjects at sites which are participating in the collection of QoL/MRU data will be asked to provide written informed consent for the collection of these personal data.
* Age =18 years and male

* Prostate cancer progression as assessed by the investigator with one of the following:
– PSA progression according to Prostate Cancer Working Group 2 (PCWG2)
criteria
– Radiographic progression in soft tissue according to Response Evaluation Criteria in Solid Tumors (RECIST) criteria or bone scans with or without PSA progression.

III or IV heart disease or left ventricular ejection fraction (LVEF) of <50% at baseline
* Known brain metastasis
* History of gastrointestinal disorders (medical disorders or extensive surgery) that may interfere with the absorption of the study drug
* Any acute toxicities due to prior chemotherapy or radiotherapy that have not resolved to a NCI-CTCAE Grade of =1. Chemotherapy induced alopecia and Grade 2 peripheral neuropathy is allowed
* Prior systemic treatment with an azole drug (eg. fluconazole, itraconazole, ketoconazole) within 4 weeks of Cycle 1, Day 1
* Current enrollment in an investigational drug or device study or participation in such a study within 30 days of Day 1
* Condition or situation which, in the investigator's opinion, may put the subjects at significant risk, may confound the study results, or may interfere significantly with the subject's participation in the study
* Subjects who have partners of childbearing potential who 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 13 weeks after last study drug administration
