Primary Outcome Measures
NameTimeMethod
Change From Baseline in Number of Daily Episodes of Urinary IncontinenceBaseline, Week 12

A urinary incontinence episode is defined as an incident of involuntary loss of urine as recorded in a patient bladder diary during the 3 days before the Baseline and Week 12 study visits. A negative number change from baseline indicates a reduction in incontinence episodes (improvement).

Secondary Outcome Measures
NameTimeMethod
Change From Baseline in Volume Voided Per MicturitionBaseline, Week 12

The total volume voided was measured over one 24-hour period in the week prior to the Baseline and Week 12 study visit and recorded by the patient in the bladder diary. This was used to calculate volume voided per micturition. A positive number change from baseline indicates an increase in volume voided per micturition (improvement).

Change From Baseline in Number of Daily Micturition EpisodesBaseline, Week 12

The number of micturition episodes (the number of times a patient urinates into the toilet) was recorded by the patient in a bladder diary during 3 consecutive days in the week prior to the Baseline and prior to the Week 12 study visit. A negative number change from baseline indicates a reduction in micturition episodes (improvement).
