Primary Outcome Measures:
  • Radiographic progression free survival (PFS) [ Time Frame: 26 months ] [ Designated as safety issue: No ]
    Time from first dose on Day 1 to the first objective evidence of radiographic progression or death due to any cause (whichever occurs first). Radiographic disease progression is defined by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 and Prostate Cancer Clinical Trials Working Group 2 (PCWG2).


Secondary Outcome Measures:
  • Overall survival [ Time Frame: 26 months ] [ Designated as safety issue: No ]
    Time from first dose on Day 1 to death due to any cause

  • Time to PSA progression [ Time Frame: 26 months ] [ Designated as safety issue: No ]
    Time from first dose on Day 1 to first observation of PSA progression

  • Change from baseline to last post baseline measurement Quality of life score using Functional Assessment of Cancer Therapy-Prostate (FACT-P) [ Time Frame: Baseline and 26 months ] [ Designated as safety issue: No ]
    The FACT-P quality of life questionnaire is a multi-dimensional, self-reported quality of life instrument specifically designed for use with prostate cancer patients

  • Change from baseline to last post baseline measurement Quality of Life score using European Quality of Life 5-Domain Scale (EQ-5D) [ Time Frame: Baseline and 26 months ] [ Designated as safety issue: No ]
    EQ-5D is a standardized instrument for use as a measure of health outcome. It provides a simple descriptive profile and a single index value for health status and is designed for self-completion by respondents

  • Change from baseline to last post baseline measurement Pain Assessments (Brief Pain Inventory - Short Form) [ Time Frame: Baseline and 26 months ] [ Designated as safety issue: No ]
    Brief Pain Inventory is a validated instrument that is a subject self-rating scale assessing level of pain, effect of the pain on activities of daily living, and analgesic use

  • Safety assessed by recording of adverse events, safety laboratory evaluations, vital signs and electrocardiograms (ECGs) [ Time Frame: 26 months ] [ Designated as safety issue: No ]
