Effects Of Dutasteride On Risk Reduction Of Acute Urinary Retention Relapse Following Trial Without Catheter
Phase 4
Terminated
- Conditions
- Benign Prostatic Hyperplasia
- Registration Number
- NCT00421421
- Lead Sponsor
- GlaxoSmithKline
- Brief Summary
The purpose of this study is to evaluate the efficacy and safety of dutasteride at reducing relapse rates of Acute Urinary Retention (AUR), including reduction in surgical intervention for benign prostatic hyperplasia (BPH), in patients who receive a 6 month treatment of dutasteride (0.5mg once daily) following a single episode of AUR followed by successful Trial Without Catheter compared with placebo.
