  Eligibility

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Male
Accepts Healthy Volunteers:   No
Criteria

Randomized, Double Blind Treatment Period:

Inclusion Criteria:

  • Histologically confirmed adenocarcinoma of the prostate without neuroendocrine differentiation or small cell features
  • Ongoing androgen deprivation therapy with a GnRH analogue or bilateral orchiectomy
  • Progressive disease despite androgen deprivation therapy as defined by rising PSA levels or progressive soft tissue or bony disease
  • No prior treatment with cytotoxic chemotherapy
  • Asymptomatic or mildly symptomatic from prostate cancer

Exclusion Criteria:

  • Severe concurrent disease, infection, or co-morbidity that, in the judgment of the Investigator, would make the patient inappropriate for enrollment
  • Known or suspected brain metastasis or active leptomeningeal disease
  • History of another malignancy within the previous 5 years other than curatively treated non-melanomatous skin cancer

Open-Label Treatment Period:

The following inclusion criteria apply to patients receiving enzalutamide or placebo during double-blind treatment.

Eligible patients must meet all inclusion criteria.

  • Received randomized double-blind treatment in PREVAIL;
  • Open-label day 1 visit is within 6 months after this amendment is approved and becomes effective at the study site;
  • Is willing to maintain androgen deprivation therapy with a gonadotropin-releasing hormone (GnRH) agonist/antagonist or has had a bilateral orchiectomy;

The exclusion criteria apply only to patients starting new treatment with enzalutamide after receiving placebo as randomized treatment. Each patient must not meet any of the following criteria:

  • Has taken commercially available enzalutamide (Xtandi);
  • Severe concurrent disease, infection, or co-morbidity that, in the judgment of the Investigator, would make the patient inappropriate for enrollment
  • Known or suspected brain metastasis or active leptomeningeal disease
