Conditions

Incontinence, Obesity, Overactive Bladder

Brief summary

This study evaluated the effectiveness of trospium chloride extended release (XR) in obese female patients with overactive bladder (OAB). Patients received either placebo and trospium chloride XR or placebo only. The study assessed the change from baseline in urinary frequency, urgency, and incontinence for trospium chloride XR versus a placebo-pill. The study was 14 weeks in duration.

Interventions

DRUGTrospium Chloride, Extended Release (XR)

Trospium chloride extended release 60 mg capsule taken orally once daily for 12 weeks.

OTHERplacebo

Placebo capsule taken orally once daily for either 2 weeks or 14 weeks.

Design outcomes

Primary

MeasureTime frameDescription
Percent Change From Baseline in Urinary Urgency Incontinence (UUI)Baseline (Week 2), Week 14Patients recorded information about UUI (accidental leakage, urgency associated with void and urgency severity) in a 3-day diary at Baseline (Week 2) and Week 14. The daily average episodes of UUI was the sum of all UUI episodes over valid diary days during the 3-day diary period divided by the valid number of diary days with at least one valid bladder entry. The percent change from baseline was calculated as (Mean UUI at Week 14- Mean UUI at Week 2)/ Mean UUI at Week 2 X 100. A negative number percent change from baseline indicated an improvement.

Outcome results

Primary

Percent Change From Baseline in Urinary Urgency Incontinence (UUI)

Patients recorded information about UUI (accidental leakage, urgency associated with void and urgency severity) in a 3-day diary at Baseline (Week 2) and Week 14. The daily average episodes of UUI was the sum of all UUI episodes over valid diary days during the 3-day diary period divided by the valid number of diary days with at least one valid bladder entry. The percent change from baseline was calculated as (Mean UUI at Week 14- Mean UUI at Week 2)/ Mean UUI at Week 2 X 100. A negative number percent change from baseline indicated an improvement.

Population: Modified Intent-to-Treat (mITT) defined as all patients who were randomized and received at least one dose of study medication. Analysis below was done on patients from the mITT population who completed the study at Week 14 and who had data available for this outcome measure.
