Show details


- Severe concurrent disease, infection, or co-morbidity that, in the judgment of the

- 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:

Study Phase  ICMJE Phase 3
Study Design  ICMJE Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Triple (Participant, Investigator, Outcomes Assessor)

Intervention  ICMJE
  • Drug: Enzalutamide
    Participants received enzalutamide 160 mg, administered as four 40-mg capsules, once per day by mouth.

  • Drug: Placebo
    Participants received placebo, administered as four capsules, once per day by mouth. Study drug treatment continued until disease progression (evidence of radiographic progression, a skeletal-related event, or clinical progression) and the initiation of a cytotoxic chemotherapy or an investigational agent, unacceptable toxicity, or withdrawal.
