Primary Outcome Measures:
  • Radiographic progression-free survival (rPFS) [ Time Frame: Day 1 to radiographic disease progression or death ] [ Designated as safety issue: No ]
    Time from randomization to radiographic disease progression or death from any cause, whichever occurs first

  • Overall survival (OS) [ Time Frame: Time from date of patient randomization to the date of patient death due to any cause ] [ Designated as safety issue: No ]
    Overall survival


Secondary Outcome Measures:
  • 50% prostate specific antigen (PSA) response at 12 weeks [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
    50% PSA response at 12 weeks

  • Changes in circulating tumor cell (CTC) counts [ Time Frame: 24 weeks ] [ Designated as safety issue: No ]
    Favorable changes in CTC levels at 24 weeks

  • Time to pain progression [ Time Frame: From randomization to the end of treatment ] [ Designated as safety issue: No ]
    Time to pain progression as measured by worst pain item in the Brief Pain Inventory-Short Form (BPI-SF) and changes in opioid analgesic use, if any


Estimated Enrollment: 1454
Study Start Date: May 2010
Estimated Study Completion Date: June 2013
Estimated Primary Completion Date: June 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Orteronel + prednisone Drug: Orteronel + prednisone
Orteronel and prednisone will be administered orally twice a day continuously throughout the study. Patients will also receive concomitant gonadotropin-releasing hormone (GnRH) analogue therapy unless they have previously undergone orchiectomy and have a testosterone concentration of <50 ng/dL.
Placebo Comparator: Placebo + prednisone Drug: Placebo + prednisone
Placebo and prednisone will be administered orally twice a day continuously throughout the study. Additionally, all patients will receive concomitant gonadotropin-releasing hormone (GnRH) analogue therapy unless they have previously undergone orchiectomy and a testosterone concentration of <50 ng/dL.
