A Safety and Efficacy Study of Oral MDV3100 in Chemotherapy-Naive Patients With Progressive Metastatic Prostate Cancer
Not Recruiting
Trial ID: NCT01212991
Purpose
The purpose of this study is to determine the benefit of enzalutamide versus placebo as
assessed by overall survival and progression-free survival in patients with progressive
metastatic prostate cancer who have failed androgen deprivation therapy but not yet received
chemotherapy.
Official Title
PREVAIL: A MULTINATIONAL PHASE 3, RANDOMIZED, DOUBLE-BLIND, PLACEBO-CONTROLLED EFFICACY AND SAFETY STUDY OF ORAL MDV3100 IN CHEMOTHERAPY-NAÏVE PATIENTS WITH PROGRESSIVE METASTATIC PROSTATE CANCER WHO HAVE FAILED ANDROGEN DEPRIVATION THERAPY

Eligibility
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
Intervention(s):
drug: Placebo
drug: Enzalutamide
