Outcomes

Primary Outcomes

Change From Baseline to End of Treatment in Overactive Bladder Questionnairre (OAB-q) Symptom Bother Score

The OAB-q is used to assess how much a patient is bothered by OAB symptoms \& the impact of these symptoms on the patient's Health Related Quality of Life(HRQL). It is a patient administered tool comprised of 33 items, where the first 8 define symptom bother with raw score being converted to a scale of 0 to 100. Higher score values are indicative of greater symptom severity or bother, and a lower score in change from baseline indicates improvement. End of Treatment results include patients who had early discontinuation from the study. Change is calculated as End of Treatment - Baseline.

Time frame: Baseline and 12 Weeks

Secondary Outcomes

Change From Baseline to Each Visit in Symptom Bother Utilizing the OAB-q Score

The OAB-q is used to assess how much a patient is bothered by OAB symptoms and the impact of these symptoms on the patient's HRQL. It is a validated patient administered tool comprised of 33 items, where the first 8 items define symptom bother with raw score being converted to a scale of 0 to 100. Higher score values are indicative of greater symptom severity or bother, and a lower score in change from baseline indicates improvement. Change is calculated as Actual Data for each timepoint - Baseline.

Time frame: Baseline, Week 4, Week 8 and Week 12

Change From Baseline to Each Visit in OAB-q Health Related Quality of Life (HRQL) Total Score

The OAB-q is used to assess how much a patient is bothered by OAB symptoms and the impact of these symptoms on the patient's HRQL. It is a validated patient administered tool comprised of 33 items, where items 9 - 33 define HRQL with raw score being converted to a scale of 0 to 100. Higher score values are indicative of better HRQL, and a positive score in change from baseline indicates improvement. Change is calculated as Actual Data for each time point - Baseline.

The PPBC is a validated, global assessment tool using a 6-point Likert scale which requires patients to assess their bladder condition by selecting one of the following responses: 1=Does not cause me any problem at all; 2=Cause me some very minor problems; 3=Causes me some minor problems; 4=Causes me (some) moderate problems; 5=Causes me severe problems; 6=Causes me many severe problems Improvement is defined by any reduction in PPBC score. End of Treatment results include patients who had early discontinuation from the study. Change is calculated as End of Treatment (EOT) - Baseline

Patient Perception of Treatment Benefit at the End of Treatment in the Global Assessment Score of the Benefit, Satisfaction, and Willingness (BSW) Questionnaire

The BSW questionnaire is a validated instrument that can be used to assess patient satisfaction with antimuscarinic agents for OAB. It is designed to capture the patient's perception of the effect of treatment in terms of relative benefit, patient satisfaction, and patient intention or willingness to continue on therapy.

Change From Baseline to Each Visit in the OAB-q HRQL Sub-domain Scores of Coping, Concern, Sleep and Social

The OAB-q is used to assess how much a patient is bothered by OAB symptoms \& the impact on the patient's HRQL. It is comprised of 33 items, with raw scores for each sub-domain being converted to a scale of 0 to 100. Higher score values are indicative of better HRQL, and a positive score in change from baseline indicates improvement. Change is calculated End of Treatment (EOT) for each sub-domain - Baseline.

Change From Baseline in Work Productivity Assessment Index (WPAI)

The WPAI is a tool used to evaluate the effect of solifenacin succinate on a patient's overall satisfaction \& quality of life, and included 6 questions regarding the effect that bladder condition had on ability to perform work-related functions \& carry out daily activities over the past 4 weeks. The scores were converted to percentages for reporting. A negative score in Change from Baseline indicates improvement. End of Treatment results include patients who had early discontinuation from the study. Change from baseline is based on the ANCOVA model after adjusting baseline value \& center.

Change From Baseline in the Treatment Satisfaction Visual Analog Scale (TS-VAS)

The TS-VAS is a instrument utilized to further evaluate the effect of solifenacin succinate on patients' overall satisfaction \& quality of life. Each patient completed a TS-VAS to rate satisfaction with treatment. They were to answer the following question: "Are you satisfied with your treatment?" by placing a mark on a line that ran from 0 (no, not at all) to 100 (yes, completely).

Change From Baseline to End of Treatment in Mean Parameters Per 24 Hours Recorded in 3-day Diary

The mean parameters recorded for previous 24 hours in the 3-day diary were: number of micturitions, number of incontinence episodes, number of urgency episodes, number of nocturia episodes and number of nocturnal voids.
