Overview
Brief Summary
This study will assess the safety and efficacy of botulinum toxin Type A for the treatment of urinary incontinence overactive bladder in patients with a spinal cord injury or multiple sclerosis.
Detailed Description
Botulinum toxin Type A 300U has been discontinued from the study after regulatory approval of botulinum toxin Type A 200U. Patients remaining in the study who were allocated to receive botulinum toxin Type A 300U at treatment 2 (and had not yet received it) will receive botulinum toxin Type A 200U instead.

Eligibility Criteria
Inclusion Criteria
- •Urinary incontinence as a result of neurogenic overactive bladder due to spinal cord injury or multiple sclerosis
- •Inadequate response to anticholinergic medication used to treat overactive bladder.

Arms & Interventions
botulinum toxin Type A 200U
Botulinum toxin Type A 200U injection into the detrusor on Day 1 followed by a repeat botulinum toxin Type A 200U injection after a minimum of 12 weeks (if applicable).
Intervention: botulinum toxin Type A
botulinum toxin Type A 300U
Botulinum toxin Type A 300U injection into the detrusor on Day 1 followed by a repeat botulinum toxin Type A 300U injection after a minimum of 12 weeks (if applicable).
Intervention: botulinum toxin Type A
Placebo/botulinum toxin Type A 200U
Placebo (Normal Saline) injection into the detrusor on Day 1 followed by a botulinum toxin Type A 200U injection after a minimum of 12 weeks (if applicable).
Intervention: botulinum toxin Type A
Placebo/botulinum toxin Type A 200U
Placebo (Normal Saline) injection into the detrusor on Day 1 followed by a botulinum toxin Type A 200U injection after a minimum of 12 weeks (if applicable).
Intervention: Normal Saline (Placebo)
Placebo/botulinum toxin Type A 300U
Placebo (Normal Saline) injection into the detrusor on Day 1 followed by a botulinum toxin Type A 300U injection (200U after discontinuation of 300U) after a minimum of 12 weeks (if applicable).
Intervention: botulinum toxin Type A
Placebo/botulinum toxin Type A 300U
Placebo (Normal Saline) injection into the detrusor on Day 1 followed by a botulinum toxin Type A 300U injection (200U after discontinuation of 300U) after a minimum of 12 weeks (if applicable).
Intervention: Normal Saline (Placebo)
Outcomes
Primary Outcomes
Change From Baseline in Forced Expiratory Volume in One Second (FEV1)
Time Frame: Baseline, Week 6
Spirometry was conducted according to American Thoracic Society standards. A spirometer was used to measure FEV1, the maximum amount of air exhaled in one second, at Baseline and Week 6. The highest value at each time-point was recorded. A positive change from Baseline indicated improvement.
Change From Baseline in Forced Vital Capacity (FVC)
Time Frame: Baseline, Week 6
Spirometry was conducted according to American Thoracic Society standards. A spirometer was used to measure FVC, the maximum amount of air exhaled from the lungs after taking the deepest breath possible, at Baseline and Week 6. A positive change from Baseline indicated improvement.
Change From Baseline in FEV1/FVC Ratio
Time Frame: Baseline, Week 6
The FEV1/FVC ratio was calculated by dividing the FEV1 value by the FVC value representing the portion (or ratio) of FVC exhaled in one second. A positive change from Baseline indicated improvement.
Secondary Outcomes
- Change From Baseline in the Number of Urinary Incontinence Episodes(Baseline, Week 6)
- Change From Baseline in the Maximum (Amplitude) Detrusor Pressure (MDP)(Baseline, Week 6)
- Change From Baseline in Maximum Cystometric Capacity (MCC)(Baseline, Week 6)
