Trial Outcomes & Findings for An Efficacy and Safety Study of Oxybutynin Chloride Oral Osmotic Therapeutic System (OROS) in Korean Overactive Bladder Participants (NCT NCT00613327)

NCT ID: NCT00613327

Last Updated: 2013-11-19

Results Overview

Goal achievement was measured by using the 6-point Likert scale (0=not achieved at all and 5=completely achieved). Achievement of treatment goal was defined by a score of 4 or 5 in the Likert scale. Percentage of participants who achieved their treatment goal defined at Baseline (for a maximum of 3 items among the 10 items including incontinence, urinary urgency, frequent urination, nocturnal frequent urination, tenesmus, general health, life habit, activity, pain/pressure pain, and sexual function) was reported.

Oxybutynin Chloride OROS
Oxybutynin chloride osmotic release oral system (OROS) tablet at starting dose of 10 milligram (mg) orally once daily. The dose was adjusted by 10 mg every 2 weeks up to first 6 weeks, based on the criteria for evaluation of optimal dose. The optimal dose obtained in first 6 weeks was continued up to Week 12.

PRIMARY outcome

Timeframe: Week 12

Population: ITT population included all participants who received study drug at least once and had data for efficacy evaluation (goal achievement in treatment) available. Missing data at Week 12 were imputed using last observation carried forward (LOCF).

Goal achievement was measured by using the 6-point Likert scale (0=not achieved at all and 5=completely achieved). Achievement of treatment goal was defined by a score of 4 or 5 in the Likert scale. Percentage of participants who achieved their treatment goal defined at Baseline (for a maximum of 3 items among the 10 items including incontinence, urinary urgency, frequent urination, nocturnal frequent urination, tenesmus, general health, life habit, activity, pain/pressure pain, and sexual function) was reported.

Timeframe: Baseline and Week 12

Population: ITT population included all participants who received study drug at least once and had data for efficacy evaluation (goal achievement in treatment) available. Here 'N' (Number of Participants Analyzed) signifies those participants who were evaluable for this measure.

Participants assessed their bothering for overactive bladder symptom by completing POSQ rated on a 5-point scale: how much they were bothered by urinary urgency (strong micturition desire indicated) in the past two weeks. The responses were indicated as: 1 (not bothered at all), 2 (slightly bothered), 3 (average), 4 (strongly bothered) and 5 (very strongly bothered). Number of participants with change from Baseline in the response to this question at Week 12 was reported.

Participants assessed their bothering for overactive bladder symptom by completing POSQ rated on a 5-point scale: how much they were bothered by daytime frequent urination (frequent urination was required more than the frequency desired during daytime) in the past two weeks. The responses were indicated as: 1 (not bothered at all), 2 (slightly bothered), 3 (average), 4 (strongly bothered) and 5 (very strongly bothered). Number of participants with change from Baseline in the response to this question at Week 12 was reported.

Participants assessed their bothering for overactive bladder symptom by completing POSQ rated on a 5-point scale: how much they were bothered by urge urinary incontinence (involuntary voiding or urinary leakage due to sudden micturition desire, not by sneezing, coughing or laughing) in the past two weeks. The responses were indicated as: 1 (not bothered at all), 2 (slightly bothered), 3 (average), 4 (strongly bothered) and 5 (very strongly bothered).

SECONDARY outcome

Timeframe: Week 12

Population: ITT population included all participants who received study drug at least once and had data for efficacy evaluation (goal achievement in treatment) available. Here 'N' (Number of Participants Analyzed) signifies those participants who were evaluable for this measure.

Participant's perception about decrease in the most bothering symptom of overactive bladder (defined at Baseline) was evaluated by using visual analogue scale (VAS) at Week 12. The total score range was 0 to 100 where 0=symptom disappeared and 100=symptom unchanged or worsened compared to Baseline.

The PPTB was used to assess participant's perception about treatment benefit and satisfaction of the study drug. Regarding benefit, participants indicated whether they had any benefit obtained from the treatment. If yes, then the participants indicated whether it was weak benefit or strong benefit. Regarding satisfaction, participants indicated whether they were satisfied with the treatment. If yes, then they indicated if the treatment was slightly satisfactory or very satisfactory. If no, then they indicated if the treatment was slightly unsatisfactory or very unsatisfactory.

Participant's perception about bladder condition was evaluated by using self administered PPBC questionnaire. Participants answered "Which of the following statements describes your bladder condition best at the moment?" on a 6-point scale: 1= not problematic at all, 2=mild problem, 3=more or less a mild problem, 4=moderate problem, 5=severe problem and 6=very severe problem.

Timeframe: Baseline, Week 6, 12 or early discontinuation (ED)

Population: ITT population included all participants who received study drug at least once and had data for efficacy evaluation (goal achievement in treatment) available. Here, 'n' specifies those participants who were evaluable for specific categories at given time point.

The OAB-q was used to evaluate influence of overactive bladder symptom on health-related quality of life (HRQL). It consisted of 2 parts: Symptom bother (6 items) evaluating how much symptoms related to overactive bladder were bothering in the last 4 weeks and HRQL (13 items) evaluating how general symptoms related to the bladder influenced life in the last 4 weeks. Each item was rated on 6-point Likert scale: 1 (not at all) to 6 (a very great deal). Total score range: 6 to 36 for symptom bother and 13 to 78 for HRQL. Transformed score calculated as (\[Actual total raw score - lowest possible value of raw score\]/range)\*100 for symptom bother where higher score indicates greater symptom bother and as (\[Highest possible raw score-Actual total raw score\]/Raw score range)\*100 for HRQL where higher scores indicate better HRQL. Transformed score range: 0-100 for both, symptom bother and HRQL.
