| NCT01314872 | A Study of the Efficacy and Safety of Vibegron (MK-4618) in Participants With Overactive Bladder (OAB) (MK-4618-008) | PHASE2 | COMPLETED | 1,395 | — | — | Mar 31, 2011 | Oct 10, 2013 | Feb 4, 2019 | - | — |
Participants were required to keep a voiding diary, recording the occurrence of each micturition. The average daily number of micturitions was calculated as the total number of micturitions that occurred over a week (4 to 10 days) during the Base Study, divided by the total number of days of voiding kept in the participant's diary. Baseline was defined as the average daily number of daily micturitions that occurred during the week of placebo run-in prior to Week 0 visit.
