Purpose

The purpose of this study is to evaluate the safety and effectiveness of oxybutynin extended release tablets 10 mg plus tamsulosin HCl 0.4 mg in the treatment of lower urinary tract symptoms as measured by change of the total International Prostate Symptom Score (I-PSS) from baseline to Week 12 or the Final Visit.

Primary Outcome Measures:

Change of the total International Prostate Symptom Score (I-PSS) from baseline to Week 12 or the Final Visit.

Secondary Outcome Measures:

At all timepoints assessed and final visit: I-PSS (total score, irritative component score, quality of life score); Symptom Problem Index score; Urgency and frequency scales scores; Incontinence Indicator scale score

Estimated Enrollment:	350
Study Start Date:	May 2004
Study Completion Date:	June 2005

Detailed Description:

The objective of this double-blind (neither the patient nor the physician knows whether drug or placebo is being taken, or at what dosage), randomized (patients are assigned different treatments based on chance), parallel group trial is to evaluate the safety and effectiveness of oxybutynin extended release tablets 10 mg per day for 12 weeks in conjunction with an alpha-blocker for the treatment of lower urinary tract symptoms (LUTS). The hypothesis of the study is that oxybutynin extended release tablets 10 mg plus tamsulosin 0.4 mg will be more effective than tamsulosin 0.4 mg plus placebo in the treatment of lower urinary tract symptoms as measured by change of the total International Prostate Symptom Score (I-PSS) from baseline to Week 12 or the Final Visit. Safety assessments include Peak Flow Rate (PFR) and Post-Void Residual (PVR) volume, adverse events, vital signs and physical exams.

Patients will receive oxybutynin extended release 10 mg plus tamsulosin 0.4 mg or placebo plus tamsulosin 0.4 mg every day for 12 weeks.
