Summary
The purpose of this study is to determine the efficacy and safety of oral enzalutamide compared to bicalutamide in castrate men with metastatic prostate cancer who have progressed while on Luteinizing Hormone Receptor Hormone (LHRH) agonist/antagonist or after receiving a bilateral orchiectomy.
Research Details
  • An open-label period has been added to the main protocol. Following unblinding at the end of the double-blind period and demonstration of a statistically significant advantage of enzalutamide over bicalutamide as assessed by the primary endpoint, all ongoing enzalutamide treated participants and ongoing or previous bicalutamide treated participants that meet entry criteria will be offered open-label enzalutamide at the discretion of the participant and study investigators.

Primary Outcome Measures
  • Progression Free Survival (PFS) Based on Independent Central Review (ICR) Assessment; From randomization until the data cut-off date of 19 October 2014, median duration of treatment was 11.6 months in the enzalutamide arm and 5.8 months in the bicalutamide arm.
Secondary Outcome Measures
  • PFS Based on Investigator Assessment; From randomization until the data cut-off date of 19 October 2014, median duration of treatment was 11.6 months in the enzalutamide arm and 5.8 months in the bicalutamide arm.; Prostate-specific Antigen (PSA) Response by Week 13; Baseline to Week 13; Best Prostate-specific Antigen (PSA) Response; Baseline to the data cutoff date of 19 October 2014, median duration of treatment was 11.6 months in the enzalutamide arm and 5.8 months in the bicalutamide arm.; Time to PSA Progression; From randomization until the data cutoff date of 19 October 2014, median duration of treatment was 11.6 months in the enzalutamide arm and 5.8 months in the bicalutamide arm.; Time to PSA ≤ 4 ng/mL; From randomization until the data cutoff date of 19 October 2014, median duration of treatment was 11.6 months in the enzalutamide arm and 5.8 months in the bicalutamide arm.; Time to ≥ 30% PSA Decline From Baseline; From randomization until the data cutoff date of 19 October 2014, median duration of treatment was 11.6 months in the enzalutamide arm and 5.8 months in the bicalutamide arm.; Time to ≥ 50% PSA Decline From Baseline; From randomization until the data cutoff date of 19 October 2014, median duration of treatment was 11.6 months in the enzalutamide arm and 5.8 months in the bicalutamide arm.; Time to ≥ 90% PSA Decline From Baseline; From randomization until the data cutoff date of 19 October 2014, median duration of treatment was 11.6 months in the enzalutamide arm and 5.8 months in the bicalutamide arm.; Radiographic PFS Based on ICR Assessment; From randomization until the data cutoff date of 19 October 2014, median duration of treatment was 11.6 months in the enzalutamide arm and 5.8 months in the bicalutamide arm.; Percentage of Participants With an Objective Response; From randomization until the data cutoff date of 19 October 2014, median duration of treatment was 11.6 months in the enzalutamide arm and 5.8 months in the bicalutamide arm.; Percentage of Participants With Adverse Events; From initiation of study drug up to 30 days after the last dose of study drug or the 30-day safety follow-up visit, whichever occurred last. Median duration of treatment was 11.6 months in the enzalutamide arm and 5.8 months in the bicalutamide arm.

  • Inclusion Criteria:
  • - Histologically confirmed adenocarcinoma of the prostate without neuroendocrine
  • differentiation or small cell features
  • - Ongoing androgen deprivation therapy with a Luteinizing Hormone Receptor Hormone
  • (LHRH) agonist or antagonist at a stable dose and schedule within 4 weeks of
  • randomization or bilateral orchiectomy (i.e., surgical or medical castration)
  • - Metastatic disease documented by one of the following:
  • - At least two bone lesions on bone scan, or
  • - Soft tissue disease documented by computed tomography (CT)/ magnetic resonance
  • imaging (MRI), or

  • value should be ≥ 2 µg/L (2 ng/mL);
  • - Soft tissue disease progression defined by Response Evaluation Criteria in Solid
  • Tumors (RECIST) 1.1;
  • - Bone disease progression defined by two or more new lesions on bone scan
  • - Asymptomatic or mildly symptomatic from prostate cancer (i.e. the score on the Brief
  • Pain Inventory-Short Form (BPI-SF) Question #3 must be < 4); no use of opiate
