               -  Subject has experienced frequency of micturition on average ≥ 8 times per 24-hour
                  period during the 3-day micturition diary period (incontinence episode should not

               -  Subject must experience at least 1 episode of urgency (grade 3 or 4) per 24-hour
                  period (with or without urgency incontinence) during the 3 day micturition diary
