A Study to Evaluate the Efficacy, Safety and Tolerability of Mirabegron and Solifenacin Succinate Alone and in Combination for the Treatment of Overactive Bladder

The average number of micturitions (urinations) per 24 hours was derived from the number of urinations (excluding incontinence only episodes) per day recorded by the participant in the micturition diary for 3-days before the Baseline and Week 12 clinic visits.

The average number of incontinence episodes (any involuntary leakage of urine) per day was derived from the number of incontinence episodes recorded by the participant in the micturition diary for 3-days before the Baseline and Week 12 clinic visits.

The average volume voided per micturition was calculated from the volume of each micturition measured by the participant and recorded in a micturition diary for 3 days before the Baseline and each post-baseline clinic visit.

The average number of micturitions (urinations) per 24 hours was derived from the number of urinations (excluding incontinence only episodes) per day recorded by the participant in the micturition diary for 3-days before the Baseline and each post-baseline clinic visit.

A responder is defined as a participant with at most 8 micturitions per 24 hours post-baseline and a negative change (i.e. an improvement) from Baseline.

The average number of incontinence episodes (any involuntary leakage of urine) per day was derived from the number of incontinence episodes recorded by the participant in the micturition diary for 3-days before the Baseline and each post-baseline clinic visit.

The percentage of participants with no incontinence episodes for the 3 days prior to each clinic visit derived from the micturition diary recorded by the participant.

The percentage of participants with at least a 50% decrease from Baseline in mean number of incontinence episodes per 24 hours during the 3 days prior to each clinic visit derived from the participant's micturition diary.

Urgency incontinence is the involuntary leakage of urine accompanied by or immediately preceded by urgency, and was derived from the number of incontinence episodes classified by the participant in a 3-day micturition diary as Grade 3 or 4 on the Patient Perception of Intensity of Urgency Scale: 0 = No urgency; 1 = Mild urgency; 2 = Moderate urgency, could postpone voiding a short while; 3 = Severe urgency, could not postpone voiding; 4 = Urge incontinence, leaked before arriving to the toilet.

The average number of urgency episodes (the sudden, compelling desire to pass urine, which is difficult to defer), derived from urgency episodes classified by the participant in the 3-day micturition diary as grade 3 or 4 on the Patient Perception of Intensity of Urgency Scale: 0: No urgency; 1: Mild urgency; 2: Moderate urgency, could delay voiding a short while; 3: Severe urgency, could not delay voiding; 4: Urge incontinence, leaked before arriving to the toilet.

Average of participants' ratings on the degree of urgency associated with each micturition and/or incontinence episode recorded in the 3-day micturition diary according to the Patient Perception of Intensity of Urgency Scale: 0: No urgency; 1: Mild urgency; 2: Moderate urgency, could delay voiding a short while; 3: Severe urgency, could not delay voiding; 4: Urge incontinence, leaked before arriving to the toilet.

The average number of times a participant recorded a new pad used per day during the 3-day micturition diary period.

Nocturia is defined as waking at night one or more times to void. The average number of times a participant urinated (excluding incontinence only episodes) during sleeping time per day was derived from the 3-day micturition diary.

The PPBC scale is a global assessment tool that asks patients to rate their impression of their current bladder condition on a 6-point scale from 1: 'Does not cause me any problems at all'; 2: 'Causes me some very minor problems'; 3: 'Causes me some minor problems'; 4: 'Causes me (some) moderate problems'; 5: 'Causes me severe problems' and 6: 'Causes me many severe problems'. A negative change from Baseline score indicates improvement.

Improvement was defined as at least a 1-point improvement (decrease) from Baseline in PPBC score.

Major improvement was defined as at least a 2-point improvement (decrease) from Baseline in PPBC score.

Deterioration was defined as at least a 1 point increase from Baseline in PPBC score.

Overactive bladder symptoms were assessed using the symptom bother scale of the overactive bladder questionnaire. The symptom bother scale consists of 8 questions answered by the participant on a scale from 1-6. The total symptom bother score was calculated from the 8 answers and then transformed to range from 0 to 100, with 100 indicating worst severity. A negative change from Baseline in symptom bother score indicates improvements.

Health-related quality of life was assessed by the HRQL subscales (coping, concern, sleep and social interaction) of the overactive bladder questionnaire (OABq). The HRQL total score was calculated by adding the 4 HRQL subscale scores, and transforming to a scale from 0 to 100, with higher scores indicating better quality of life. A positive change from Baseline in HRQL score indicates improvements.

The EQ-5D is an international, standardized, nondisease-specific (i.e., generic) instrument for describing and valuing health status. Participants were asked to indicate which of the following statements best describes their health state:

I have no problems in walking about; I have some problems in walking about; I am confined to bed.

In the table below, each row title lists Baseline health status first followed by End of Treatment health status and reports the number of patients in that category.

The EQ-5D is an international, standardized, generic instrument for describing and evaluating health status. Health status is assessed by patients evaluating their health on a vertical, visual analog scale from 0 to 100 where the endpoints are labeled 'Worst imaginable health state' (=0) and 'Best imaginable health state' (=100). On the EQ-5D VAS, a positive change from baseline indicates improvement.

This 6-item assessment measures productivity losses during the past 7 days and includes measures on work time missed due to health, impairment while working due to health (the participant's assessment of the degree to which health affected their productivity while working), overall work impairment due to health (takes into account both hours missed due to health and the participant's assessment of the degree to which health affected their productivity while working) and activity impairment due to health (the degree in which health problems affected their ability to do regular daily activities). Scores for each measure are expressed from 0 to 100 with higher numbers indicating greater impairment and less productivity, i.e., worse outcomes. A negative change from baseline indicates improvement.

The TS-VAS is a visual analog scale (VAS) that asks patients to rate their satisfaction with treatment by placing a vertical mark on a 10 cm line where the endpoints are labeled 'No, not at all' on the left (=0) to 'Yes, completely satisfied' on the right (=10). A positive change from Baseline indicates improvement.
