Primary Outcome Measures:
  • Pathological Complete Response Rate [ Time Frame: 6 months ] [ Designated as safety issue: No ]
    To assess the pathological complete response rate following triplet therapy (MDV3100 in combination with leuprolide and dutasteride) and MDV3100 alone when administered as neoadjuvant therapy for 6 months prior to prostatectomy in patients with localized prostate cancer


Secondary Outcome Measures:
  • PSA [ Time Frame: 6 Months ] [ Designated as safety issue: No ]
    To determine the effects on prostate-specific antigen (PSA) (including median nadir value, percentage of patients achieving PSA < 0.2 ng/mL, the proportion of patients achieving 50% and 90% decrease in PSA, and time to PSA nadir) for triplet therapy and MDV3100 alone

  • Determine the rate of positive surgical margins [ Time Frame: 6 months ] [ Designated as safety issue: No ]
    To determine the rate of positive surgical margins, extracapsular extension, positive seminal vesicles and lymph nodes at the time of prostatectomy for triplet therapy and MDV3100 alone.

  • Pharmacodynamics [ Time Frame: 6 months ] [ Designated as safety issue: No ]
    To determine the effects of triplet therapy and MDV3100 alone on selected pharmacodynamic markers on prostatectomy specimens including apoptosis, mitotic index, androgen receptor signaling, and others.

  • Determine effects on testosterone and dihydrotestosterone (DHT) [ Time Frame: 6 months ] [ Designated as safety issue: No ]
    To determine the effects on testosterone and dihydrotestosterone (DHT) (including median values of testosterone and DHT during and at completion of therapy) for triplet therapy and MDV3100 alone

  • Assess the safety and tolerability of triplet therapy and MDV3100 alone [ Time Frame: 6 months ] [ Designated as safety issue: Yes ]
    To assess the safety and tolerability of triplet therapy and MDV3100 alone in the neoadjuvant setting. Safety and tolerability will be documented throughout the study by assessment of adverse events, vital signs, electrocardiograms (ECGs), and laboratory assessments
