RATIONALE: Diagnostic procedures, such as ultrasound-guided biopsy, may help find prostate cancer. Dutasteride may improve the ability of ultrasound-guided biopsy to find prostate cancer. It is not yet known whether dutasteride followed by ultrasound-guided biopsy is more effective than a placebo followed by ultrasound-guided biopsy in finding prostate cancer.
PURPOSE: This randomized phase III trial is studying dutasteride and ultrasound-guided biopsy to see how well they find prostate cancer compared with a placebo and ultrasound-guided biopsy.
|Condition or disease||Intervention/treatment||Phase|
|Prostate Cancer||Drug: dutasteride Other: placebo||Phase 3|
- Determine the efficacy of dutasteride followed by contrast-enhanced, ultrasound-guided targeted biopsy in detecting prostate cancer.
- Determine the detection rate of prostate cancer with targeted biopsy using contrast-enhanced ultrasound combined with dutasteride.
- Determine the efficacy of targeted biopsy using contrast-enhanced ultrasound vs systematic biopsy in diagnosing clinically significant prostate cancer.
- Determine the reduction in post-biopsy bleeding after dutasteride in these patients.
- Determine the cost effectiveness of this regimen in these patients.
OUTLINE: This is a prospective, double-blind, placebo-controlled, randomized study. Patients are randomized to 1 of 2 arms.
- Arm I: Patients receive oral dutasteride once daily on days 1-14.
- Arm II: Patients receive oral placebo once daily on days 1-14. On day 14, patients in both arms undergo blood collection and contrast-enhanced (perflutren protein-type A microspheres) transrectal ultrasound. Conventional gray-scale imaging, color Doppler imaging, and power Doppler imaging are performed. Biopsies are then performed; first up to 6 targeted ultrasound-guided biopsies and then up to 12 systematic biopsies.
After completion of study procedures, patients are followed at 1 day.
PROJECTED ACCRUAL: A total of 450 patients will be accrued for this study.
