Effects On Dihydrotestosterone Regulated Gene Expression In Benign Prostatic Hyperplasia Or Prostate Cancer

A randomized, open-label, parallel-group pilot study, to assess the pharmacodynamic effect on dihydrotestosterone regulated gene expression, longitudinally and in a dose dependent manner, of 0.5mg or 3.5mg dutasteride administered orally once daily, for three months in men with symptomatic benign prostatic hyperplasia or during the period between baseline and radical prostatectomy in men with biopsy-proven, clinically localized prostate cancer.
