Conditions: Urge Urinary Incontinence Overactive Bladder
Allocation: RANDOMIZED | Intervention model: PARALLEL
Enrollment: 645
Healthy volunteers: yes

Brief summary:
Six hundred and thirty-six women diagnosed with urge urinary incontinence (UUI) by a three-item self-administered questionnaire (3IQ) will be randomized to 12 weeks of fesoterodine or matching placebo. The study will take place at up to 14 clinical sites in the US. All participants who complete the 12-week randomized trial will be offered open-label fesoterodine for an additional 9 months.

The hypothesis of the randomized controlled trial is that among women diagnosed with urge incontinence using the 3IQ, fesoterodine is more effective than placebo in reducing the mean number of urge incontinence episodes per day.

Detailed description:

Arms:
arm 1: fesoterodine 4 mg (1 tablet) for 2 weeks with the option to increase to fesoterodine 8 mg or stay at fesoterodine 4 mg for 10 weeks for a total of 12 weeks of study medication. arm 2: placebo (an identical pill that contains no medication) 1 tablet daily for 2 weeks followed by the option to increase the placebo pill daily for 10 weeks for a total of 12 weeks of study placebo medication.

Interventions: intervention 1: Fesoterodine intervention 2: Matching Placebo
Intervention descriptions: intervention 1: Participants will be instructed to take one tablet of blinded study medication once a day, orally, for 12 weeks. They will start with a 4 mg dose of study medication and will have the option of doubling that dose after 2 or 4 weeks if they wish. At the end of the 12 week blinded trial, participants will be offered open-label fesoterodine (Toviaz™), for 9 months beginning at 4 mg with participant directed dose adjustment. intervention 2: Participants will be instructed to take one tablet of blinded study medication once a day, orally, for 12 weeks. They will start with a 4 mg dose of study medication and will have the option of doubling that dose after 2 or 4 weeks if they wish. At the end of the 12 week blinded trial, participants will be offered open-label fesoterodine (Toviaz™), for 9 months beginning at 4 mg with participant directed dose adjustment.
