Primary Outcome Measures:
  • Overall survival (OS) [ Time Frame: Time from patient randomization to death from any cause ] [ Designated as safety issue: No ]
    Patients will be followed for survival until 80% of patients have died or are lost to follow-up

Secondary Outcome Measures:
  • 50% prostate specific antigen (PSA) response at 12 weeks [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
  • Pain response at 12 weeks [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
  • Radiographic progression-free survival (rPFS) [ Time Frame: Time from patient randomization to radiographic disease progression or death from any cause, whichever occurs first ] [ Designated as safety issue: No ]

  • Radioisotope therapy or external beam radiation therapy within 4 weeks of first dose of study drug
  • Documented central nervous system metastases
  • Treatment with any investigational compound within 30 days prior ro first dose of study drug (Patients who are in long-term follow-up following active treatment in other trials are eligible)
