Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
Participants recruited for this study were men and women with overactive bladder (OAB) who had received 1 or more antimuscarinics in the past and who were dissatisfied with their last antimuscarinic treatment due to lack of efficacy (provided that their previous antimuscarinic was not solifenacin).

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
Participants entered a 2-week, single-blind, placebo run-in period and completed a daily diary (including 3 consecutive days prior to the randomization visit for micturition and incontinence). After this, participants' eligibility criteria were re-confirmed and they were then randomized into the double-blind treatment period of the study.

Reporting Groups
  Description
Mirabegron 50 mg Participants who received mirabegron 50 mg once daily for 12 weeks.
Solifenacin 5 mg Participants who received solifenacin 5 mg once daily for 12 weeks.

[1] SAF population. The number of participants are 933 and 932. A micturition is any voluntary urination (excluding incontinence only episodes). The mean number of micturitions per 24 hours were calculated from the data recorded by the participant during the 3-day micturition diary period.

Mean (Standard Deviation)
 2.1  (2.30)   2.1  (2.05)   2.1  (2.17) 
[1] SAF population with baseline value > 0. The number of participants are 410 and 424. An incontinence episode is any involuntary leakage of urine. The mean number of incontinence episodes per 24 hours were calculated from the data recorded by the participant during the 3-day micturition diary period.

 1.9  (1.99)   2.0  (1.94)   2.0  (1.96) 
[1] SAF population with baseline value > 0. The number of participants are 401 and 413. An urgency incontinence episode is any involuntary leakage of urine accompanied by or immediately proceeded by urgency. The mean number of urgency incontinence episodes per 24 hours were calculated from the data recorded by the participant during the 3-day micturition diary period.

[1] SAF population with baseline value > 0. The number of participants are 931 and 931. An urgency episode is a sudden compelling desire to pass urine immediately followed by an incontinent event or the patient having to rush to the toilet and make it in time; severity recorded as 3 (severe urgency) or 4 (urgency incontinence) on the Patient Perception of the Intensity of Urgency Scale (PPIUS) validated scale. The mean number of urgency episodes per 24 hours were calculated from the data recorded by the participant during the 3-day micturition diary period.
