Outcomes

Primary Outcomes

Change from Baseline in mean number of micturitions per 24 hours at Week 12

Time Frame: Micturtions will be assessed prior to randomization and at Week 12 (Visit 6).

Micturition events will be recorded by subjects in an eDiary using a smartphone device during 3-day diary periods prior to randomization and at 12 weeks.
