S0421, Docetaxel and Prednisone With or Without Atrasentan in Treating Patients With Stage IV Prostate Cancer and Bone Metastases That Did Not Respond to Previous Hormone Therapy

DISEASE CHARACTERISTICS:

• Histologically confirmed adenocarcinoma of the prostate
• Stage IV disease (any T, any N, M1b)
• Evidence of bone metastases by bone scan or MRI
• Measurable or nonmeasurable disease
• Soft tissue disease that has been irradiated within the past 2 months is not assessable as measurable disease
• Hormone-refractory disease despite androgen deprivation and antiandrogen withdrawal, as defined by 1 of the following criteria:
• Prostate-specific antigen (PSA) progression, defined as 3 consecutive rising PSA levels* taken ≥ 1 week apart
• PSA ≥ 5 ng/mL NOTE: *If the third confirmatory PSA level is the second level
• Progression of measurable disease
• Progression of nonmeasurable disease by bone scan
• Must have undergone surgical or medical (e.g., luteinizing hormone-releasing hormone [LHRH] agonist [e.g., leuprolide or goserelin] or LHRH antagonist therapy) castration
• Patients who have undergone medical castration must continue LHRH agonist or antagonist therapy during study treatment
• Must have completed 12 courses of blinding protocol treatment (atrasentan/placebo) AND stopped docetaxel for any reason (including completion of 12 courses) other than progressive disease
• No symptomatic pleural effusion
• No third space fluid accumulation (e.g., ascites)
• No prior or concurrent brain metastases
• Patients with clinical evidence of brain metastases must have a negative brain CT scan or MRI within the past 8 weeks

Other

• More than 4 weeks since prior investigational drugs
• Concurrent bisphosphonates allowed provided therapy is started prior to study entry, dose is maintained during the first 12 weeks of study treatment, and patient meets criteria for disease progression
