|Brief Title ICMJE||Cyproterone Acetate in Treating Patients With Newly Diagnosed Stage III or Stage IV Prostate Cancer|
|Official Title ICMJE||Intermittent Hormone Therapy for Newly Diagnosed Metastatic Prostate Cancer|
RATIONALE: Androgens can cause the growth of prostate cancer cells. Hormone therapy, such as cyproterone acetate may stop the adrenal glands from making androgens. Sometimes the tumor may not need treatment until it progresses. In this case, observation may be sufficient. It is not yet known whether giving cyproterone acetate continuously is more effective than giving cyproterone acetate after tumor progression in treating prostate cancer.
PURPOSE: This randomized phase III trial is studying cyproterone acetate to compare how well it works when given continuously or after tumor progression in treating patients with newly diagnosed stage III or stage IV prostate cancer.
OUTLINE: This is a randomized, multicenter study.
All patients receive cyproterone acetate daily for 16 weeks. Patients also receive monthly injections of luteinizing hormone-releasing hormone (LHRH) agonist beginning in week 2 and continuing for 14 weeks. Patients with a prostate-specific antigen (PSA) level of ≤ 4 ng/mL and who are asymptomatic at 14 weeks are randomized to 1 of 2 treatment arms.
Quality of life is assessed every 6 months for 2 years and then annually thereafter.
Quality of life is assessed every 6 months and when therapy is restarted.
Pain and performance status are assessed at each visit in both treatment arms.
After completion of study therapy, patients are followed periodically.
PROJECTED ACCRUAL: A total of 900 patients will be accrued for this study.
