ListOutcomeTime frameDescription
PrimaryChange From Baseline (CFB) to the End of 12-Week Treatment Period in Mean Number of Micturition/24 Hours in Mirabegron 50 mg GroupBaseline, week 12
A micturition was defined as any voluntary act of passing urine (excluding incontinence only episodes). The mean number of micturitions per 24 hours was calculated as the average number of times a participant urinated per day during the 3-day micturition diary period.
SecondaryNumber of Participants With Treatment Emergent Adverse EventsFrom first dose up to 30 days after last dose (up to week 16)
AE was defined as any untoward medical occurrence in a participant administered a study drug or had undergone study procedures and which did not necessarily have had a causal relationship with the treatment. An abnormality identified during a medical test (e.g., laboratory parameter, vital sign, Electrocardiography (ECG) data, and physical exam) was defined as an AE only if the abnormality induced clinical signs or symptoms or requires active intervention or requires interruption or discontinuation of study medication or the abnormality or investigational value was clinically significant in the opinion of the investigator. Treatment emergent AE was defined as an AE observed after starting administration of the IP and 30 days after the final administration of study drug.
SecondaryChange From Baseline to Week 12 in Post Void Residual (PVR) VolumeBaseline, week 12PVR was assessed by ultrasonography.
SecondaryChange From Baseline in Mean Number of Grade 3 or 4 Patient Perception of Intensity of Urgency Scale (PPIUS) Urgency Episodes Per 24 HoursBaseline and weeks 4, 8, and 12
Urgency was defined as a complaint of a sudden, compelling desire to pass urine, which was difficult to defer. An urgency episode was defined as any micturition or incontinence episode with a severity of grade 3 or 4, assessed by participants based on the PPIUS, where grade 0 = No urgency; grade 1 = Mild urgency; grade 2 = Moderate urgency, could delay voiding a short while; grade 3 = Severe urgency, could not delay voiding; grade 4 = Urge incontinence, leaked before arriving to the toilet. The mean number of urgency episodes (grade 3 and/or 4) per day was calculated as the average number of times a participant recorded an urgency episode (grade 3 and/or 4) with or without incontinence per day during the 3-day micturition diary period.
SecondaryChange From Baseline in Mean Number of Daytime Incontinence Episodes Per 24 HoursBaseline and weeks 4, 8, and 12
An incontinence episode was defined as an episode with any involuntary loss of urine. Daytime was defined as time between waking up in the morning and going to sleep later the same day or next day. The mean number of incontinence episodes was determined using the patient diary data recorded by the participant in the 7 days prior to baseline visit and at various specified time-intervals.
SecondaryChange From Baseline in Mean Number of Nighttime Incontinence Episodes Per 24 HoursBaseline and weeks 4, 8, and 12
An incontinence episode was defined as an episode with any involuntary loss of urine. Nightime was defined as time between between going to sleep on a day and waking up on the same or next day. The mean number of incontinence episodes was determined using the patient diary data recorded by the participant in the 7 days prior to baseline visit and at various specified time-intervals.
SecondaryChange From Baseline in Mean Number of Urge Incontinence Episodes Per 24 HoursBaseline and weeks 4, 8, and 12
An incontinence episode was defined as an episode with any involuntary loss of urine. The mean number of urge incontinence episodes per 24 hours was determined using the patient diary data recorded by the participant in the 7 days prior to baseline visit and at various specified time-intervals.
SecondaryChange From Baseline in OAB Symptom Score (OABSS)Baseline and weeks 4, 8, and 12
The OABSS questionnaire was a questionnaire completed by participants with 4 questions regarding their OAB symptoms: Daytime Frequency ("How many times do you typically urinate from waking in the morning until sleeping at night?" where scores range from 0-2), Nighttime Frequency ("How many times do you typically wake up to urinate from sleeping at night until waking in the morning?" where scores range from 0-3), Urgency ("How often do you have a sudden desire to urinate, which is difficult to defer?" where scores range from 0-5), Urgency Incontinence ("How often do you leak urine because you cannot defer the sudden desire to urinate?" where scores range from 0-5). The total score ranges from 0 to 15 with higher score indicating more symptoms.
SecondaryChange From Baseline in Mean Number of Micturition Per 24 HoursBaseline and weeks 4 and 8
A micturition was defined as any voluntary act of passing urine (excluding incontinence only episodes). The mean number of micturitions per 24 hours was calculated as the average number of times a participant urinated per day during the 3-day micturition diary period.
