Participants aged 5 years to < 18 years received solifenacin orally once a day, with sequential titrated doses for 12 weeks to identify the optimal dose during the dose-titration period. The initial dose was pediatric equivalent dose (PED) 5 mg.
After completing the dose titration period participants entered the fixed-dose period during which solifenacin was taken orally once a day for 40 weeks or until the end of study visit (Week 52).

The purpose of this study was to investigate a medicine for the treatment of symptoms and complications of neurogenic detrusor overactivity (NDO) in children and adolescents.

A study to assess the long term effect, safety and metabolism of a solifenacin liquid suspension in participants 5 to 18 years of age with neurogenic detrusor overactivity

The NDO often occurs in patients with spina bifida or other spinal cord damage where the bladder muscle contracts more than normal during filling. These patients often have an inability to void, so that catheterization is required to empty the bladder.

The medicine being tested in this study is called solifenacin succinate. Solifenacin tablets are given to adults for the treatment of overactive bladder. A new liquid suspension has been developed to treat children and adolescents in this and other studies. 

The efficacy and safety of the solifenacin suspension was investigated. The take-up and length of time that the solifenacin suspension stays in the body was also  investigated during this study. Effectiveness was measured by urodynamics (the filling and emptying of the bladder) and the urine volumes during catheterization together with the diary responses relating to the number of incontinence episodes or incontinence free days.

Safety assessments included analysis of the blood and urine, review of the electrocardiogram (ECG), ultrasound of the kidney, simple memory and understanding tests (cognitive function) and the ability to see near and far objects (visual accommodation).

The full analysis set (FAS) consisted of all participants who had a baseline and 1 post baseline measurement for the primary endpoint (MCC) and have received at least 1 dose of study drug.

Change from Baseline Week 24

Change from Baseline Week 24 (LOCF)

During urodynamic assessments, the bladder was filled until voiding/leakage begins, or until it was stopped because either the participant experiences pain or discomfort or 135% of expected bladder capacity for age has been reached. MCC is the maximum bladder capacity reached during filling cystometry before either leakage or pain/discomfort was observed.

Analysis of change from baseline to Week 24.

Analysis of change from baseline to Week 24 LOCF.

The full analysis set (FAS) consisted of all participants who had a baseline and 1 post baseline measurement for the primary endpoint (MCC) and have received at least 1 dose of study drug. Last observation carried forward (LOCF) was utilized.

Change from Baseline to Week 24 in Maximum Cystometric Capacity (MCC)

During urodynamic assessments, the bladder was filled until voiding/leakage begins, or until it was stopped because either the participant experiences pain or discomfort or 135% of expected bladder capacity for age has been reached. MCC is the maximum bladder capacity reached during filling cystometry before either leakage or pain/discomfort was observed. Based on study requirements, the last possible titration step was Week 9 for participants enrolled under versions 1.0 and 1.1 and Week 12 under later versions.

The full analysis set (FAS) consisted of all participants who had a baseline and 1 post baseline measurement for the primary endpoint (MCC) and have received at least 1 dose of study drug. The number of participant analyzed represents participants with a non-missing change from baseline to last possible titration step.

Change From Baseline to Last Possible Titration Step in Maximum Cystometric Capacity

Bladder compliance gives an indication of the elasticity of the bladder wall and was calculated by dividing the change in volume by the change in detrusor pressure during the filling of the bladder.

Change from Baseline in Bladder Compliance

Change from baseline in the bladder volume was calculated using urodyanamic assessments. During urodynamic assessments, the bladder is filled until voiding/leakage begins, or until it is stopped because either the subject experiences pain or discomfort or 135% of expected bladder capacity for age has been reached. If no detrusor contraction of at least 15 cmH2O occurs, the bladder volume was imputed with MCC.

Change from Baseline in Bladder Volume (mL) Until First Detrusor Contraction > 15 cmH2O as a Percentage of Expected Bladder Capacity (EBC)

Bladder volumes at 30 cm H2O detrusor pressure was calculated using the urodynamic assessments. During urodynamic assessments, the bladder is filled until voiding/leakage begins, or until it is stopped because either the participants experiences pain or discomfort or 135% of expected bladder capacity for age has been reached.

Analysis of change from baseline to Week 24 in bladder volume at 30 cmH20.

Analysis of change from baseline to Week 24 LOCF in bladder volume at 30 cmH20.

The full analysis set (FAS) consisted of all participants who had a baseline and 1 post baseline measurement for the primary endpoint (MCC) and have received at least 1 dose of study drug. Last observation carried forward (LOCF) was utilized. Only participants who reached 30 cmH20 detrusor pressure were included in the analysis.

Change from Baseline in Bladder Volume at 30 cmH2O Detrusor Pressure

Bladder volumes at 40 cm H2O detrusor pressure were calculated using urodynamic assessments. During urodynamic assessments, the bladder is filled until voiding/leakage begins, or until it is stopped because either the subject experiences pain or discomfort or 135% of expected bladder capacity for age has been reached.

Analysis of change from baseline to week 24 in bladder volume at 40 cmH20.

Analysis of change from baseline to week 24 LOCF in bladder volume at 40 cmH20.

The full analysis set (FAS) consisted of all participants who had a baseline and 1 post baseline measurement for the primary endpoint (MCC) and have received at least 1 dose of study drug. Last observation carried forward (LOCF) was utilized. Only participants who reached 40 cmH20 detrusor pressure were included in the analysis.

Change from Baseline in Bladder Volume at 40 cmH2O Detrusor Pressure

Change from baseline in number of overactive detrusor contractions until end of bladder filling was measured by urodynamic testing. If leakage occurred, the “Detrusor pressure at leakage” was recorded otherwise the volume of fluid instilled into the bladder was recorded.

Change from Baseline in Number of Overactive Detrusor Contractions (> 15 cmH2O) Until End of Bladder Filling

The bladder was filled until voiding/leakage began or until it was stopped because either the participant experiences pain or discomfort or 135% of expected bladder capacity for age has been reached. Pressure was recorded for an extra 5 minutes after leakage began or the end of bladder-filling, whichever is sooner.

Change from Baseline in Detrusor Pressure at the End of Bladder Filling

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 are concurrent.

Change from Baseline in Average Catheterized Volume per Catheterization

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.

Change from Baseline in Maximum Catheterized Volume
