USS is 5-item scale measuring urinary urgency; range is 1 (no feeling of urgency) to 5 (unable to hold; leak urine). Change calculated as UUI episodes per 24 hours at observation divided by baseline number of UUI episodes per 24 hours, multiplied by 100.
Time frame: Baseline, Week 1, Week 4, Week 12
Change From Baseline in Mean Voided Volume Per Micturition.
Mean voided volume calculated as sum of voided volume divided by the total number of micturition episodes with a recorded voided volume greater than 0 in the 3-day diary at that visit.
Time frame: Baseline, Week 1, Week 4, Week 12
Change From Baseline in Mean Number of Micturitions Per 24 Hours.
The mean number of micturitions was calculated as the sum of all micturitions divided by the total number of diary days collected at that visit. Change calculated as mean at observation minus mean at baseline.

Percent Change From Baseline of Micturitions Per 24 Hours.
Percent change of micturitions per 24 hours was calculated as change in 24-hour mean at that visit divided by the baseline 24-hour mean multiplied by 100 (ie, 100% \*(Week 12 or 4 - baseline)/baseline).
Time frame: Baseline, Week 1, Week 4, Week 12
Change From Baseline in Mean Number of Nocturnal Micturitions Per 24 Hours.
Mean number of nocturnal micturitions per 24 hours was calculated as the sum of all micturitions divided by the total number of diary days collected at that visit. Nocturnal (Bedtime) was defined as the time the subject went to bed until he/she arose to start the next day.
Time frame: Baseline, Week 1, Week 4, Week 12
Percent Change From Baseline of Nocturnal Micturitions Per 24 Hours.
Percent change of nocturnal micturitions per 24 hours was calculated as change in 24-hour mean at that visit divided by the baseline 24-hour mean multiplied by 100 (ie, 100% \*(Week 12 or 4 - baseline)/baseline). Nocturnal (Bedtime) was defined as the time the subject went to bed until he/she arose to start the next day.
Time frame: Baseline, Week 1, Week 4, Week 12
Change From Baseline in Mean Number of Urgency Episodes Per 24 Hours.
Mean number urgency episodes (USS rating \>= to 3 in diary) per 24 hours calculated as sum of all micturitions divided by total number of diary days collected at visit. USS: 5-item scale measuring urinary urgency; range is 1 (no feeling of urgency) to 5 (unable to hold; leak urine). Change calculated as mean at observation minus mean at baseline.
Time frame: Baseline, Week 1, Week 4, Week 12
Percent Change From Baseline of Urgency Episodes Per 24 Hours.
Percent change of urgency episodes (USS rating \>= to 3 in diary) per 24 hours calculated as change in 24-hour mean at that visit divided by the baseline 24-hour mean multiplied by 100. USS: 5-item scale measuring urinary urgency; range is 1 (no feeling of urgency) to 5 (unable to hold; leak urine).
Time frame: Baseline, Week 1, Week 4, Week 12
Change From Baseline in Mean Number of Severe Urgency Episodes Per 24 Hours.
Mean number of severe urgency episodes (USS rating \>= to 4 in diary ) per 24 hours: sum of all micturitions divided by total number of diary days collected at that visit. USS: 5-item scale to measure urinary urgency; range: 1 (no feeling of urgency) to 5 (unable to hold; leak urine). Change calculated as mean at observation minus mean at baseline.
Time frame: Baseline, Week 1, Week 4, Week 12
Percent Change From Baseline of Severe Urgency Episodes Per 24 Hours.
Percent change calculated as change in severe urgency episodes (USS rating \>= to 4 in diary ) per 24 hours at that visit divided by the baseline number of severe urgency episodes per 24 hours, multiplied by 100. USS is 5-item scale measuring urinary urgency; range is 1 (no feeling of urgency) to 5 (unable to hold; leak urine).
Time frame: Baseline, Week 1, Week 4, Week 12
Change From Baseline in Mean USS Rating Per Micturition Per 24 Hours.
Mean USS rating calculated as the sum of rating scores on USS per 24 hours divided by the mean number of micturitions per 24 hours at that visit. USS is 5-item scale measuring urinary urgency; range is 1 (no feeling of urgency) to 5 (unable to hold; leak urine). Change calculated as mean at observation minus mean at baseline.

Time frame: Baseline, Week 1, Week 4, Week 12
Change From Baseline in Overactive Bladder Questionnaire (OAB-q): Symptom Bother Score at Week 12 (End of Treatment).
Symptom bother score derived as sum of scores for questions 1-8; lowest possible raw score: 8; highest possible score: 48. Data analyzed based on transformation of the score to a 0 to 100 scale \[(Actual total raw score - lowest possible value of raw score)/by raw score range \* 100\]. Higher transformed scores indicative of greater symptom bother. Negative change in Symptom Bother score indicates improvement. Change calculated as score at observation minus score at baseline.
Time frame: Baseline, Week 12
Change From Baseline in OAB-q: Health Related Quality of Life (HRQL) at Week 12 (End of Treatment).
HRQL domain and total raw score derived as sum of scores (6-point scale: 1=not at all/none of the time; 6=a very great deal/all of the time). Transformed score (Total HRQL or domain)=\[(Highest possible raw score-Actual total raw score)/Raw score range\]x100. Higher transformed scores indicative of better HRQL. Positive change in HRQL scores indicates improvement. Change: score at observation minus score at baseline.
