A Trial Comparing Combination Treatment (Solifenacin Plus Mirabegron) With One Treatment Alone (Solifenacin)

The mean number of incontinence episodes (complaint of any involuntary leakage of urine) per day was derived from number of incontinence episodes recorded on valid diary days during the 3-day micturition diary period divided by the number of valid diary days during the 3-day micturition diary period.

The average number of micturitions (voluntary urinations (excluding incontinence only episodes)) per 24 hours was derived from number of micturitions recorded on valid diary days during the 3-day micturition diary period divided by the number of valid diary days during the 3-day micturition diary period (excluding incontinence only episodes).

The number of incontinence episodes (complaint of any involuntary leakage of urine) per day was derived from total number of incontinence episodes on valid diary days recorded during the 3-day micturition diary period.

MVV per micturition was defined as MVV (mL) per micturition during last 3 days of the 3-day micturition diary period. MVV per micturition was calculated as the sum of each volume voided for each record with volume voided > 0 on valid diary days divided by the total number of records with a volume voided > 0 on valid diary days during the 3-day micturition diary period.

CMF was defined as the mean number of micturitions per 24 hours that participants would have at EoT if their fluid intake had remained unchanged since baseline. This was calculated by the MVV per Micturition at baseline multiplied by the mean number of micturitions per 24 hours at baseline divided by the MVV per micturition at EoT.

UI was defined as the complaint of involuntary urine leakage accompanied by or immediately preceded by urgency. UI was measured using the Patient Perception of Intensity of Urgency Scale (PPIUS), a patient reported outcome validated 5-point categorical scale rating the degree of associated urinary urgency severity (0=No urgency, I felt no need to empty my bladder, but did so for other reasons. 1=Mild, I could postpone voiding as long as necessary, without fear of wetting myself. 2= Moderate, I could postpone voiding for a short while, without fear of wetting myself. 3=Severe, I could not postpone voiding, but had to rush to the toilet in order not to wet myself. 4=Urgency incontinence, I leaked before arriving to the toilet). One urgency incontinence episode was counted for each record of the diary in which the following occurred: incontinence episode or 'both' was recorded \& severity of urinary urgency recorded was 3 or 4.

Number of UI episodes was calculated using the number of UI episodes recorded on valid diary days during the 3-day micturition diary period. NOTE: Only urgency incontinence episodes recorded on a valid diary day were counted.

An urgency episode was defined as the complaint of a sudden, compelling desire to pass urine, which is difficult to defer. The mean number of urgency episodes (severity of 3 or 4) per 24 hours was defined as the average number of times a participant recorded an urgency episode (severity of 3 or 4) with or without incontinence per day during the 3-day micturition diary period. Measured using the PPIUS scale. This was calculated using the sum of each record with an urgency episode (severity of 3 or 4) recorded on a valid diary day divided by the number of valid diary days during the 3-day micturition diary period.

The mean number of pads per 24 hours was defined as the average number of times a participant recorded a new pad used per day during the 3-day micturition diary period. This was calculated using the number of new pads used during valid diary days during the 3-day micturition diary period divided by the number of valid diary days during the 3-day micturition diary period.

The number of pads used was defined as the number of times a participant recorded a new pad used during the 3-day micturition diary period. This was calculated using the sum of each record with new pad checked. Only records with new pad checked on a valid diary day were counted.

Mean number of nocturia episodes was defined as the number of times a participant urinated (excluding incontinence only episodes) while sleeping during the 3-day diary period, divided by the number of valid diary days during the diary period. Night time episode of incontinence only was not considered a nocturia episode. Nocturia episodes were counted for each micturition record which occurred between the date/time of going to bed with intention to sleep and the date/time of getting up with intention to stay awake on a valid diary day \& which was accompanied by a sleep interruption. Nocturia only determined for those who were not night-shift workers.

The number of nocturia episodes was defined as the number of times a participant urinated (excluding incontinence only episodes) during sleeping time during the 3-day micturition diary period. This was calculated using the sum of each nocturia episode recorded on valid diary days during the 3-day micturition diary period.

The EQ-5D is an international, standardized, nondisease specific instrument for describing and valuing health status. It has 5 dimensions: Mobility, Self-care, Usual Activities, Pain/Discomfort, and Anxiety/Depression. Each dimension has 5 response levels: level 1=no problem or none; level 2=slight problems; level 3=moderate problems; level 4=severe problems; level 5=unable to perform activity.

The OAB-q was a self-reported questionnaire comprising 33-items each rated on a 6-point Likert scale. The questionnaire consisted of an 8-item symptom bother scale and 25 health-related QoL (HRQL) items comprising 4 HRQL subscales (Coping, Concern, Sleep, and Social Interaction). Symptom Bother score ranges from 0 (least severity) to 100 (worst severity).
