Primary Outcome Measures
NameTimeMethod
Percent Change From Baseline in Average Daily Cough-induced Stress Urinary Incontinence (SUI) Episodes at Week 12Baseline and week 12

Cough-induced SUI episodes were assessed using an event-driven electronic Incontinence Diary where the participant recorded the main cause of each urinary incontinence episode as coughing, another stress reason, or other cause. Episodes of incontinence were recorded for the week before baseline and treatment visit. Average daily cough induced SUI episodes were calculated as (sum of daily cough-induced SUI episodes in a week)/number of days recorded. The percent change from baseline in the average daily cough-induced SUI episodes to Week 12 are presented.

Secondary Outcome Measures
NameTimeMethod
Percentage of Participants With Adverse EventsUp to ~16 weeks

An AE is defined as any untoward medical occurrence in a participant, temporally associated with the use of study treatment, whether or not considered related to the study treatment. The number of participants who experienced an adverse event are presented.

Percentage of Participants Who Discontinued Study Intervention Due to AEsUp to ~14 weeks

An AE is defined as any untoward medical occurrence in a participant, temporally associated with the use of study treatment, whether or not considered related to the study treatment. The number of participants who discontinued study intervention due to an adverse event are presented.
