Dutasteride Followed By Ultrasound-Guided Biopsy in Finding Prostate

Status Completed

Clinical Trial Summary

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.

Clinical Trial Description

OBJECTIVES:

- 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. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
