Trial Outcomes & Findings for Web-based Methodology Trial to Evaluate the Efficacy and Safety of Tolterodine ER in Subjects With Overactive Bladder (NCT NCT01302938)

Out of 237 participants screened, 118 participants received single-blind placebo matched to tolterodine 4 milligram (mg) capsule once daily during run-in period for 2 weeks. Only 18 participants were randomized to receive double-blind treatment due to early termination of the study.

Web-based Methodology Trial to Evaluate the Efficacy and Safety of Tolterodine ER in Subjects With Overactive Bladder

Micturitions include episodes of voluntary micturition and episodes of Urgency Urinary Incontinence (UUI). UUI episodes were defined as those micturitions with Urinary Sensation Scale (USS) rating of 5 in the diary in participants with UUI at baseline. USS rating 5: Unable to hold; leak urine. The mean number of micturitions per 24 hours was calculated as the total number of micturitions divided by the total number of diary days collected at that visit.

Mean voided volume per micturition was calculated as sum of voided volume divided by the total number of micturition episodes with a recorded voided volume greater than 0 at that visit. Baseline values for each time point were calculated separately considering only those participants who were evaluable at the given time point.

UUI episodes were defined as those with the Urinary Sensation Scale (USS) rating of 5 in the diary. USS total range 1 to 5: 1. No feeling of urgency, 2. Mild feeling of urgency, 3. Moderate feeling of urgency, 4. Severe feeling of urgency, 5. Unable to hold; leak urine. Baseline values for each time point were calculated separately considering only those participants who were evaluable at the given time point.

Baseline values for each time point were calculated separately considering only those participants who were evaluable at the given time point.

Nocturnal micturitions were defined as micturitions with USS rating 1-5 that occurred between the time the participant went to bed and the time he or she arose to start the next day. USS rating: 1. No feeling of urgency, 2. Mild feeling of urgency, 3. Moderate feeling of urgency, 4. Severe feeling of urgency, 5. Unable to hold; leak urine. The mean number of nocturnal micturitions per 24 hours was calculated as the total number of nocturnal micturitions divided by the total number of diary days collected at that visit.

The mean number of micturition-related nocturnal urgency episodes per 24 hours was calculated as the total number of micturitions with USS rating of greater than or equal to (\>=) 3 that occurred between time participant went to bed and time participant arose to start next day divided by the total number of days that diary data was collected at that visit. USS total range 1 to 5: 1. No feeling of urgency, 2. Mild feeling of urgency, 3. Moderate feeling of urgency, 4. Severe feeling of urgency, 5. Unable to hold; leak urine.

The mean number of micturition-related urgency episodes per 24 hours was calculated as the total number of micturitions with USS rating of \>= 3 divided by the total number of days that diary data was collected at that visit. USS total range 1 to 5: 1. No feeling of urgency, 2. Mild feeling of urgency, 3. Moderate feeling of urgency, 4. Severe feeling of urgency, 5. Unable to hold; leak urine. Baseline values for each time point were calculated separately considering only those participants who were evaluable at the given time point.

PPBC: self-administered,single-item questionnaire to describe participant's perception of bladder-related problems. PPBC assessed on 6-point scale:1=no problems at all,2=some very minor problems,3=some minor problems,4=some moderate problems,5=severe problems,6=many severe problems. Results categorized as score change (SC) from baseline on 2-point scale:improvement (negative SC),no improvement (SC 0 or more) and on 4-point scale:major improvement (SC is negative in magnitude of 2 or more), minor improvement (SC is negative in magnitude of 1), no change (SC= 0),deterioration (positive SC).

PPUS: a self-administered, single-item, validated questionnaire that measures the participant's perception of urinary urgency. It is sensitive to changes in perceptions of urinary urgency over time. Scale of 0 (usually not able to hold urine), 1 (usually able to hold urine \[without leaking\] until reaching toilet if go to toilet immediately), or 2 (usually able to finish what he/she is doing before going to toilet \[without leaking\]). Results categorized as SC from baseline on 3-point scale: improvement (positive SC), no change (SC 0), deterioration (negative SC).

OAB-q: a self-administered, 33-item, questionnaire that assesses how much the participant has been bothered by selected bladder symptoms. Each item rated by participant on Likert scale 1 (not at all) to 6 (a very great deal). Symptom bother score derived as sum of scores for items 1 to 8; lowest possible raw score: 8; highest possible score: 48. Data analyzed based on transformation of the score to a 0 to 100 scale \[(Actual total raw score - lowest possible value of raw score)/range\]\*100. Higher scores values indicative of greater symptom bother.

OAB-q: self-administered, 33-item, questionnaire, assesses how much participant has been bothered by selected bladder symptoms. Each item rated on Likert scale 1 (not at all) to 6 (a very great deal). Questions 9 to 33 constitute HRQL, includes domains (range): concern(7-42), coping(8-48), sleep(5-30), and social function(5-30). Total HRQL score (25-125) derived as sum of HRQL domains. Transformed score range 0 to 100 (HRQL domain or total) = \[(Highest possible raw score-Actual total raw score)/Raw score range\]\*100. Higher transformed scores indicate better HRQL.

Participant experience questionnaire (PEQ) is a web-based self-administered, exploratory questionnaire that assesses the participant's perception of trial method. Number of participants who responded to question 1, "Where did you hear first about the study?" are reported.

An AE was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. An SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. Treatment-emergent are events between first dose of study drug and up to 28 days after last dose that were absent before treatment or that worsened relative to pretreatment state.

AE:any untoward medical occurrence attributed to study medication in participant who received study drug. Relatedness to study medication was assessed by the investigator. Severity of AEs assessed as: mild (does not interfere with participant's usual function), moderate (interferes to some extent with participant's usual function) and severe (interferes significantly with participant's usual function). Mild, moderate and severe are not mutually exclusive; hence same participant may be included in more than 1 type of severity of AEs.
