Clinical Trial Summary

This is an investigator-initiated study of safety, efficacy and tolerability of dutasteride given for 18 months, including a 1-year double-blind randomized co-administration with either tolterodine ER or placebo in men suffering from lower urinary tract symptoms (LUTS) including urgency and frequency, with or without urgency urinary incontinence (i.e., overactive bladder (OAB) symptoms).


Clinical Trial Description

Men who are treated with an alpha blocker (AB) or 5-alpha reductase inhibitor (5-ARI) for benign prostatic enlargement (BPE) and lower urinary tract symptoms (LUTS) often have symptoms including urinary frequency and urgency. ABs and 5-ARIs may improve the obstructive voiding symptoms but not necessarily the storage symptoms.

This study will evaluate the safety and efficacy of dutasteride 0.5 mg once daily for 6 months in an open label fashion. Those patients who continue to report storage urinary symptoms, will be randomized to receive dutasteride 0.5 mg once daily for an additional one year together with double-blind tolterodine ER 4 mg or matched tolterodine ER placebo once daily. ;
