Two primary efficacy variables will be assessed for submission in the United States: change in the average number of micturitions (frequency) per 24 hours and the change in the average number of urge incontinence episodes per 24 hours. For the submissions in the European Union, the first primary variable will be the change in the average number of micturitions (frequency) per 24 hours and the co-primary variable is the treatment response, based on a treatment benefit scale. All continuous variables will be measured as changes from baseline to value after 12 weeks of treatment. The following safety variables were observed and assessed: adverse events, change in residual urinary volume (mL), change in laboratory parameters, change in vital signs, change in electrocardiogram (ECG), change in physical examination and change in urological/urogynecological examination.
