Design outcomes

Primary

MeasureTime frameDescription
Change in Number of Urinary Urge Incontinence EpisodesBaseline, Week 2, Week 6, Week 12Mean number of urinary urge incontinence episodes measured over a 7-day diary prior to week 12. Urinary urge incontinence is defined as urinary leakage associated with a strong desire to urinate.

Secondary

MeasureTime frameDescription
Change in Number of MicturitionsBaseline, Week 2, Week 6, Week 12Mean number of micturitions measured over a 7 day diary prior to each visit. Micturation is defined as urinating into the toilet.
Change in Number of Nocturia EpisodesBaseline, Week 12Mean number of nocturia episodes measured over a 7 day diary prior to each visit. A nocturia episode is a void (urinating into the toilet) that interrupts one's sleep.
Maximum Cystometric Capacity (MCC) by Urodynamic MeasurementsBaseline, Week 12Maximum Cystometric Capacity (maximum volume that the bladder can hold) measured in mean milliliters
Incontinence Quality of Life Instrument (I-QOL)Baseline, Week 2, Week 6, Week 12Measured on 3 domains; a 5-point scale (1-5) for each domain. Sum of the domain scores is normalized to a scale of 0-100 (100 = no impact of incontinence on daily activities, 0 = maximum impact of incontinence on daily activities). Mean scores presented.
