Phase 3
Terminated
Conditions
Urinary Incontinence
Overactive Bladder
Interventions
Biological: Botulinum toxin type A
Drug: Placebo
Registration Number
NCT02660138
Lead Sponsor
Ipsen
Brief Summary

The purpose of this study is to provide confirmatory evidence of the safety and efficacy of two Dysport® (AbobotulinumtoxinA) doses (600 units \[U\] and 800 U), compared to placebo in reducing urinary incontinence (UI) in adult subjects treated for neurogenic detrusor overactivity (NDO) due to spinal cord injury (SCI) or multiple sclerosis (MS).

Inclusion Criteria
  • Urinary Incontinence for at least 3 months prior to Screening as a result of Neurogenic Detrusor Overactivity due to Spinal Cord Injury or Multiple Sclerosis.
  • Subjects with Spinal Cord Injury must have a stable neurological injury at T1 level or below which occurred at least 6 months prior to Screening.
  • Subjects with Multiple Sclerosis must be clinically stable in the investigator's opinion, with no exacerbation (relapse) of MS for at least 3 months prior to Screening.
  • Subjects must have had an inadequate response after at least 4 weeks of oral medications used in the treatment of NDO (e.g. anticholinergics, beta-3 agonists) and/or have intolerable side-effects.
  • Routinely performing Clean Intermittent Catheterization (CIC) to ensure adequate bladder emptying.
  • An average of at least two episodes per day of Urinary Incontinence recorded on the screening bladder diary.

Key

Exclusion Criteria
  • Any current condition (other than NDO) that may impact on bladder function.
  • Previous or current, tumour or malignancy affecting the spinal column or spinal cord, or any other unstable cause of SCI.
  • Any condition that will prevent cystoscopic treatment administration or CIC usage, e.g. urethral strictures.
  • Current indwelling bladder catheter, or removal of indwelling bladder catheter less than 4 weeks prior to Screening.
  • BTX-A treatment within 9 months prior to Screening for any urological condition (e.g. detrusor or urethral sphincter treatments).
  • Any neuromodulation/electrostimulation usage for urinary symptoms/incontinence within 4 weeks prior to Screening. Any implanted neuromodulation device must be switched off at least 4 weeks prior to Screening.

Primary Outcome Measures
NameTimeMethod
Mean Change From Baseline in Weekly Number of UI Episodes at Week 6 of DBPC CycleBaseline and Week 6 of DBPC Cycle

The weekly number of UI episodes was measured using a 7-day bladder diary. Bladder diaries that contained data recorded on at least 5 days were included in the analysis. The least square (LS) mean of the change in weekly number of UI episodes at 6 weeks after the first study treatment was calculated using a mixed model repeated measures (MMRM) analysis.

Secondary Outcome Measures
NameTimeMethod
Mean Change From Baseline in Maximum Cystometric Capacity (MCC) at Week 6 of DBPC CycleBaseline and Week 6 of DBPC Cycle

All subjects had a standardised urodynamic (filling cystometry) assessment at baseline (screening) and again at Week 6 to determine the MCC. The LS mean of the change in MCC at 6 weeks after the first study treatment was calculated using an analysis of covariance (ANCOVA).

Mean Change From Baseline in Maximum Detrusor Pressure (MDP) at Week 6 of DBPC CycleBaseline and Week 6 of DBPC Cycle

All subjects had a standardised urodynamic filling cystometry assessment at baseline (screening) and again at Week 6 to determine the MDP. The LS mean of the change in MDP at 6 weeks after the first study treatment was calculated using an ANCOVA.

Number of Subjects With No Episodes of UI at Week 6 of DBPC CycleBaseline and Week 6 of DBPC Cycle

The weekly number of UI episodes was measured using a 7-day bladder diary. Bladder diaries that contained data recorded on at least 5 days were included in the analysis. The number of subjects with no UI episodes at 6 weeks after the first study treatment was recorded and the percentage of subjects was also calculated from the total number of subjects with any number of UI events at Week 6.

Number of Subjects With No IDCs During Storage at Week 6 of DBPC CycleBaseline and Week 6 of DBPC Cycle

All subjects had a standardised urodynamic filling cystometry assessment at baseline (screening) and again at Week 6 to determine the occurrence of IDCs. The number of subjects without IDCs at 6 weeks after the first study treatment was recorded and the percentage of subjects was also calculated from the total number of subjects with data available for analysis at Week 6.

Mean Change From Baseline in Incontinence Quality of Life (I-QoL) Questionnaire Total Summary Score at Week 6 of DBPC CycleBaseline and Week 6 of DBPC Cycle

The I-QoL questionnaire is a validated, disease-specific questionnaire designed to measure the effect of UI on subjects' QoL. It consists of 22 items in 3 domains (avoidance and limiting behaviour, psychosocial impact and social embarrassment). Subjects used a 5-point response scale for each of the 22 items with values ranging from 1 (extremely) to 5 (not at all). The total summary score was transformed to a 100 point scale ranging from 0 to 100, with higher scores indicating a better QoL. The LS mean of the change in the I-QoL total summary score at 6 weeks after the first study treatment was calculated using a MMRM analysis.

Number of Subjects With a UI Response at Improvement Levels ≥30%, ≥50%, and ≥75% at Week 6 of the DBPC CycleBaseline and Week 6 of DBPC Cycle

The weekly number of UI episodes was measured using a 7-day bladder diary. Bladder diaries that contained data recorded on at least 5 days were included in the analysis. The number of baseline UI episodes was compared with the number of UI episodes at Week 6 to determine the level of response each subject reached, i.e. a decrease of ≥30%, ≥50% or ≥75% . The number of subjects showing an improvement of ≥30%, ≥50% and ≥75% were recorded and the percentage of subjects was also calculated from the total number of subjects with any number of UI events at Week 6.

Mean Change From Baseline in Volume at First Involuntary Detrusor Contraction (Vol@1stIDC) at Week 6 of DBPC CycleBaseline and Week 6 of DBPC Cycle

All subjects had a standardised urodynamic (filling cystometry) assessment at baseline (screening) and again at Week 6 to determine the Vol@1stIDC which is the instilled volume when first IDC commences. Subjects who did not exhibit a post-treatment IDC at Week 6 had Vol@1stIDC imputed using the recorded corrected MCC volume at Week 6. The LS mean of the change in Vol@1stIDC at 6 weeks after the first study treatment was calculated using an ANCOVA.

Mean Change From Baseline in Volume Per Void at Week 6 of DBPC CycleBaseline and Week 6 of DBPC Cycle

The volume per void was measured during one 24-hour period of the 7-day bladder diary. The LS mean of the change in volume per void at 6 weeks after the first study treatment was calculated using a MMRM analysis.

Median Time Between TreatmentsDay of first treatment (baseline) and day of retreatment, up to 2 years

Duration of effect for time between treatments was calculated by: (the date of the first retreatment visit - date of first treatment administration in the DBPC cycle). The median number of days between treatments was determined based on the Kaplan-Meier method. Subjects with no retreatment were censored at the last visit.
