Overactive Bladder

Brief summary

This Phase 3B study is designed to test if a fesoterodine flexible dose regimen is more effective than placebo in reducing micturition frequency and other overactive bladder (OAB) symptoms, e.g., urgency, urgency incontinence episodes in patients with overactive bladder and if the fesoterodine regimen is safe and well tolerated.

Interventions

DRUGFesoterodine

4mg tablets once daily for 2 weeks, then either 4mg or 8mg tablets once daily for 10 weeks. Subjects were instructed to take 1 tablet every evening within 4 hours prior to bedtime with water, swallowed whole without chewing.

DRUGPlacebo

Matched placebo tablets once daily for 12 weeks. Subjects were instructed to take 1 tablet every evening within 4 hours prior to bedtime with water, swallowed whole without chewing.

Recruitment details

Participants were screened at 90 centers in the United States; in 88 centers, participants were randomized.

Pre-assignment details

The study consisted of a 2-week no-treatment screening period and a 12-week double-blind treatment period. Participants with bothersome overactive bladder (OAB) symptoms who met all entry criteria at baseline (end of screening) were randomized.

Participants by arm

Placebo
All randomized participants were treated with placebo once daily for the first 2 weeks of treatment. The dose remained as placebo once daily or changed to matching placebo (for 8 mg) once daily for the next 10 weeks based on discussion between investigator and participant.

Fesoterodine
All randomized participants were treated with fesoterodine 4mg once daily for the first 2 weeks of treatment. The dose remained at 4 mg once daily or increased to 8 mg once daily for the next 10 weeks based on discussion between investigator and participant.

Outcome results

Primary

Change in Mean Number of Micturition Episodes Per 24 Hours at Week 12 Relative to Baseline.

The number of micturitions per 24 hours was calculated as the sum of all micturitions divided by the total number of diary days collected at that visit. Change: mean at Week 12 minus mean at Baseline

Time frame: Baseline and Week 12

Population: Participants in the Full Analysis Set (FAS) with non-missing numerical change from baseline to Week 12 (last observation carried forward \[LOCF)). The FAS included all participants who took at least 1 dose of assigned study drug and had at least 1 valid efficacy assessment, either at baseline or post baseline.

Change in Overactive Bladder Questionnaire (OAB-q) at Week 12 Relative to Baseline - Health Related Quality of Life (HRQL) Subscales

Each item rated by subject on a Likert scale 1 (least symptom bother) to 6 (most symptom bother). Raw scores were transformed to a score from 0 to 100. Once transformed a positive change indicates improvement. Change: mean at Week 12 minus mean at baseline.

Time frame: Baseline and Week 12

Population: Participants in the Full Analysis Set (FAS) with non-missing numerical change from baseline to Week 12.~The FAS included all participants who took at least 1 dose of assigned study drug and had at least 1 valid efficacy assessment, either at baseline or post baseline
