Bone Metastasis-free Survival [ Time Frame: From the first dose of investigational product to the primary data cutoff date of 30 July 2010; median time on study was approximately 20 months. ] [ Designated as safety issue: No ]
The time to the first occurrence of bone metastasis (either symptomatic or asymptomatic) or death from any cause. Participants who did not experience bone metastasis or on-study death were censored at the last on-study contact date or the primary analysis data cutoff date, whichever came first. Median bone metastasis-free survival time was estimated using the Kaplan-Meier method.
Time to first occurance of bone metastasis or death from any cause

  • Time to First Bone Metastasis [ Time Frame: From the first dose of investigational product to the primary data cutoff date of 30 July 2010; median time on study was approximately 20 months. ] [ Designated as safety issue: No ]
    Time from randomization to the date of first occurrence of bone metastasis (either symptomatic or asymptomatic), excluding death. Participants who did not develop bone metastasis were censored at their last on-study bone assessment date or the primary analysis data cut-off date, whichever was first. Median time to first bone metastasis was estimated using the Kaplan-Meier method.
  • Overall Survival [ Time Frame: From the first dose of investigational product to the primary data cutoff date of 30 July 2010; median time on study was approximately 20 months. ] [ Designated as safety issue: No ]
    Time from randomization to the date of death. Participants who were still alive or lost to follow-up by the primary analysis data cut-off date were censored at their last contact date (on-study or during survival follow-up) or the primary analysis data cut-off date, whichever was first.
Time to first occurance of bone metastasis (excluding death). Overall survival.

Study on Prolonging Bone Metastasis-Free Survival in Men With Hormone Refractory Prostate Cancer
A Randomized, Double-Blind, Placebo-Controlled, Multi-Center Phase 3 Study of Denosumab on Prolonging Bone Metastasis-Free Survival in Men With Hormone Refractory Prostate Cancer

The purpose of this study is to compare the treatment effect of denosumab with placebo on prolonging bone metastasis-free survival in men with hormone refractory (androgen independent) prostate cancer who have no bone metastasis at baseline.

Inclusion Criteria:

  • men with histologically confirmed prostate cancer
  • bilateral orchiectomy at least 6 months before randomization or continuous ADT with a GnRH agonist or antagonist for at least 6 months before randomization
  • total testosterone level less than 50 ng/dL,
  • hormone refractory (androgen independent) prostate cancer demonstrated during continuous ADT/post-orchiectomy defined as: 3 consecutive PSA values with PSA1 < PSA2 < PSA3, each PSA value must be separated by at least 2 weeks, PSA2 and PSA3 greater than or equal to 1.0 ng/mL,
  • high risk for development of bone metastasis defined as PSA value greater than or equal to 8.0 ng/mL, obtained no more than 3 months before randomization OR PSA doubling time less than or equal to 10.0 months

Exclusion Criteria:

  • prior or current evidence of radiographically detectable bone metastasis
