Clinical Trial Summary

The purpose of this study was to evaluate long term efficacy and safety of treatment with solifenacin succinate (the study drug) in children with neurogenic detrusor overactivity after multiple dose administration.

Description:

In some children with a severe form of spina bifida (which is the consequence of a spinal cord defect), the bladder muscle (detrusor) contracts strongly and without warning (also known as neurogenic detrusor overactivity) and the urethra (the passage connecting the bladder with outside) does not relax. Though these children cannot void, urine leakage can happen when the overactive contractions are strong, and/or the pressure in the bladder is so high that it overcomes the closed urethra (overflow at high filling bladder pressure). This high bladder pressure puts these children at risk for kidney damage and can decrease the quality of the bladder. Therapy was aimed to decrease the high filling bladder pressure and the overactive detrusor contractions.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change From Baseline to Week 24 in Maximum Cystometric Capacity (MCC)	MCC was the volume instilled into the bladder prior to leakage or end of bladder-filling (whichever was reached first), as assessed by urodynamics (procedure: the bladder was to be filled until voiding/leakage began, or until it was stopped because either the participant experienced pain or discomfort or 135% of expected bladder capacity [EBC] was reached for participants = 2 years or of maximum catheterized volume [MCV] for participants aged 6 months to < 2 years; the participants' bladder was emptied via catheterization).	Baseline and Week 24
Secondary	Change From Baseline to Weeks 3, 6, 9, 12 and 52 in MCC	MCC was the volume instilled into the bladder prior to leakage or end of bladder-filling (whichever was reached first) as assessed by urodynamics (procedure: the bladder was to be filled until voiding/leakage began, or until it was stopped because either the participant experienced pain or discomfort or 135% of EBC was reached for participants = 2 years or of MCV for participants aged 6 months to < 2 years. The participants' bladder was emptied via catheterization).	Baseline and Weeks 3, 6, 9, 12, 52
Secondary	Change From Baseline to Weeks 3, 6, 9, 12, 24 and 52 in Bladder Compliance	Bladder compliance gives an indication of the elasticity of the bladder wall. Bladder compliance was calculated by dividing the change in volume during the filling of the bladder by the change in detrusor pressure during that change in bladder volume using urodynamic assessments. The values for bladder volume and detrusor pressure at the beginning and end of filling were taken and used.	Baseline and Weeks 3, 6, 9, 12, 24, 52
Secondary	Change From Baseline to Weeks 3, 6, 9, 12, 24 and 52 in Detrusor Pressure at End of Bladder-Filling	Detrusor pressure was expressed as bladder pressure minus intra-abdominal pressure as assessed by urodynamics.	Baseline and Weeks 3, 6, 9, 12, 24, 52
Secondary	Change From Baseline to Weeks 3, 6, 9, 12, 24 and 52 in Detrusor Pressure 5 Minutes After End of Bladder-Filling	Detrusor pressure was expressed as bladder pressure minus intra-abdominal pressure as assessed by urodynamics.	Baseline and Weeks 3, 6, 9, 12, 24, 52
Secondary	Change From Baseline to Weeks 3, 6, 9, 12, 24 and 52 in Catheterized Volume 5 Minutes After End of Bladder-Filling	Catheterized volume was measured when the bladder was emptied via catheterization 5 minutes after the end of bladder-filling.	Baseline and Weeks 3, 6, 9, 12, 24, 52
Secondary	Change From Baseline to Weeks 3, 6, 9, 12, 24 and 52 in Bladder Volume Until First Detrusor Contraction (> 15 cmH2O)	Bladder volume as assessed by urodynamics.	Baseline and Weeks 3, 6, 9, 12, 24, 52
Secondary	Change From Baseline to Weeks 3, 6, 9, 12, 24 and 52 in Bladder Volume at 10 cmH20 Detrusor Pressure	Bladder volume as assessed by urodynamics.	Baseline and Weeks 3, 6, 9, 12, 24, 52
Secondary	Change From Baseline to Weeks 3, 6, 9, 12, 24 and 52 in Bladder Volume at 20 cmH20 Detrusor Pressure	Bladder volume as assessed by urodynamics.	Baseline and Weeks 3, 6, 9, 12, 24, 52
Secondary	Change From Baseline to Weeks 3, 6, 9, 12, 24 and 52 in Bladder Volume at 30 cmH20 Detrusor Pressure	Bladder volume as assessed by urodynamics.	Baseline and Weeks 3, 6, 9, 12, 24, 52
Secondary	Change From Baseline to Weeks 3, 6, 9, 12, 24 and 52 in Number of Overactive Detrusor Contractions (> 15 cmH2O) Until Leakage or End of Bladder-Filling		Baseline and Weeks 3, 6, 9, 12, 24, 52
Secondary	Change From Baseline to Weeks 3, 6, 9, 12, 24, 36 and 52 in Average Catheterized Volume Per Catheterization	The average catheterized volume per catheterization was calculated using all available (non-zero) catheterized volumes recorded over both of the 2 measuring days in the diary, whether or not these 2 days were concurrent. Catheterized volumes were recorded for 2 days in a participant diary prior to each visit. Four to six catheterizations were performed every day.	Baseline and Weeks 3, 6, 9, 12, 24, 36, 52
Secondary	Change From Baseline to Weeks 3, 6, 9, 12, 24, 36 and 52 in Maximum Catheterized Volume (MCV)	The maximum catheterized volume per day was calculated using all available (non-zero) catheterized volumes recorded for the 2 measuring days in the diary, whether or not these 2 days were concurrent. The maximum value was calculated separately for each measuring day and the mean of these two values was used.	Baseline and Weeks 3, 6, 9, 12, 24, 36, 52
Secondary	Change From Baseline to Weeks 3, 6, 9, 12, 24, 36 and 52 in Average First Morning Catheterized Volume	The first morning catheterized volume was the volume associated with the first morning catheterization. The average first morning catheterized volume was calculated as the average of the available first morning catheterized volumes recorded for the 2 measuring days in the diary, whether or not these 2 days are concurrent.	Baseline and Weeks 3, 6, 9, 12, 24, 36, 52
Secondary	Change From Baseline to Weeks 3, 6, 9, 12, 24, 36 and 52 in Mean Number of Periods Between the Clean Intermittent Catheterizations (CICs) With Incontinence Per 24 Hours	Participants were required to have 4-6 CICs per day on a schedule fixed for the duration of the study. To calculate the number of periods between CICs with incontinence in a diary day, the diary day was divided into periods between CICs (i.e. inter-CIC periods). The hour period, rather than the exact time, of each CIC and incontinence episode was recorded in the diary. When an incontinence episode and a CIC were marked in the same hour period, the incontinence episode was counted as occurring prior to the CIC (when the bladder had not yet emptied), rather than after it (when the bladder had recently been emptied), i.e. the inter-CIC period ended with the hour in which the CIC was recorded. The mean number of periods between CICs with incontinence per 24 hours was the number of periods between CICs when incontinence occurred, divided by the total number of valid diary days.	Baseline and Weeks 3, 6, 9, 12, 24, 36, 52
Secondary	Percentage of Days With Catheterizations for Each Hour of 24 Hour Day at Baseline	For each one hour period of the 24 hour day, the percentage of days with catheterization was assessed as the number of days with catheterization occurring within the one hour period divided by the number of valid diary days over all participants.
