Overactive Bladder
Conditions
Brief summary
The purpose of this study is to assess the safety and effectiveness of botulinum toxin type A (onabotulinumtoxinA) in treating patients with idiopathic overactive bladder with urinary incontinence.
Interventions
BIOLOGICALonabotulinumtoxinA
OnabotulinumtoxinA (botulinum toxin Type A) 100 U injected into the detrusor at Day 1, followed by a repeat injection of onabotulinumtoxinA 100 U after a minimum of 12 weeks (if applicable). Or, if placebo is administered at Day 1, onabotulinumtoxinA 100 U injected after a minimum of 12 weeks (if applicable).
DRUGnormal saline
Normal saline (placebo) injected into the detrusor at Day 1.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change From Baseline in Number of Daily Episodes of Urinary Incontinence | Baseline, Week 12 | A urinary incontinence episode is defined as an incident of involuntary loss of urine as recorded in a patient bladder diary during the 3 days before the Baseline and Week 12 study visits. A negative number change from baseline indicates a reduction in incontinence episodes (improvement). |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change From Baseline in Number of Daily Micturition Episodes | Baseline, Week 12 | The number of micturition episodes (the number of times a patient urinates into the toilet) was recorded by the patient in a bladder diary during 3 consecutive days in the week prior to the Baseline and prior to the Week 12 study visit. A negative number change from baseline indicates a reduction in micturition episodes (improvement). |
| Change From Baseline in Volume Voided Per Micturition | Baseline, Week 12 | The total volume voided was measured over one 24-hour period in the week prior to the Baseline and Week 12 study visit and recorded by the patient in the bladder diary. This was used to calculate volume voided per micturition. A positive number change from baseline indicates an increase in volume voided per micturition (improvement). |

Outcome results
Primary
Change From Baseline in Number of Daily Episodes of Urinary Incontinence
A urinary incontinence episode is defined as an incident of involuntary loss of urine as recorded in a patient bladder diary during the 3 days before the Baseline and Week 12 study visits. A negative number change from baseline indicates a reduction in incontinence episodes (improvement).
Time frame: Baseline, Week 12
Population: Intent-to-treat population included all randomized patients.
| Arm | Measure | Group | Value (MEAN) | Dispersion |
|---|---|---|---|---|
| onabotulinumtoxinA | Change From Baseline in Number of Daily Episodes of Urinary Incontinence | Baseline | 5.47 Incontinence episodes | Standard Deviation 3.621 |
| onabotulinumtoxinA | Change From Baseline in Number of Daily Episodes of Urinary Incontinence | Change from Baseline at Week 12 | -2.65 Incontinence episodes | Standard Deviation 3.333 |
| Placebo/onabotulinumtoxinA | Change From Baseline in Number of Daily Episodes of Urinary Incontinence | Baseline | 5.09 Incontinence episodes | Standard Deviation 3.204 |
| Placebo/onabotulinumtoxinA | Change From Baseline in Number of Daily Episodes of Urinary Incontinence | Change from Baseline at Week 12 | -0.87 Incontinence episodes | Standard Deviation 2.833 |

The number of micturition episodes (the number of times a patient urinates into the toilet) was recorded by the patient in a bladder diary during 3 consecutive days in the week prior to the Baseline and prior to the Week 12 study visit.

| onabotulinumtoxinA | Change From Baseline in Number of Daily Micturition Episodes | Baseline | 11.98 micturition episodes | Standard Deviation 4.259 |
| onabotulinumtoxinA | Change From Baseline in Number of Daily Micturition Episodes | Change from Baseline at Week 12 | -2.15 micturition episodes | Standard Deviation 2.933 |

Secondary
Change From Baseline in Volume Voided Per Micturition
The total volume voided was measured over one 24-hour period in the week prior to the Baseline and Week 12 study visit and recorded by the patient in the bladder diary.
