Primary Outcome Measures:
  • To explore the effect of treatment with MDV3100 on androgen signaling and expression of survival/escape pathways in the bone marrow [ Time Frame: 9 weeks post baseline ] [ Designated as safety issue: No ]
    To explore the effect of treatment with MDV3100 on androgen signaling and expression of survival/escape pathways in the bone marrow of patients with castration-resistant metastatic prostate cancer in correlation with measures of antitumor activity to identify predictors of response or resistance to therapy.

Secondary Outcome Measures:
  • To explore the antitumor activity of treatment with MDV3100. [ Time Frame: 9 weeks post baseline ] [ Designated as safety issue: No ]
    To explore the antitumor activity of treatment with MDV3100 as assessed by serum prostate-specific antigen (PSA) levels, imaging of soft tissue and bone metastases, and markers of bone metabolism;
