Brief Summary:

The proposed study is a randomized, double blind placebo controlled multicenter study to determine the effectiveness of mirabegron in the treatment of neurogenic bladder dysfunction. Patients will be randomized into one of two trial arms: mirabegron 25mg for two weeks, with escalation to 50mg for the remaining 8 weeks, or matched placebo capsule for two weeks, with placebo escalation for the remaining 8 weeks. Each of these trial arms will be stratified based on whether the patient is already taking an anticholinergic medication or not. The study will treat a total of 144 patients (72 with placebo, 72 with mirabegron). The study hypothesis is that mirabegron will result in a statistically superior (increased) urodynamic bladder capacity.

The study duration is 12 weeks, with a 1-4 week run in period where no active or placebo treatment will be administered. The primary outcome measure will be based on an increase in urodynamic bladder capacity. Secondary outcome measures will be additional urodynamic parameters, urinary symptom scales, urinary quality of life indices, and voiding diary results.

Patients who are over 18 years of age with a diagnosis of multiple sclerosis (MS) or spinal cord injury (SCI) will be eligible to participate. All eligible patients will have urodynamic studies performed within 4 weeks of trial enrollment, and at the end of study (week 9-10). Adverse events and study outcomes will be assessed at predefined study time points.

Drug Information available for: Mirabegron

Arm Intervention/treatment
Experimental: Mirabegron
Patients randomised to this arm start with mirabegron 25mg PO daily for two weeks, and then at 2 weeks titrate to 50mg PO daily, and maintain that dose for the duration of the study (8 additional weeks).
Drug: Mirabegron
Mirabegron 25mg PO daily for 2 weeks, with dose increase to Mirabegron 50mg PO daily for the remaining 8 weeks.

Placebo Comparator: Placebo
Inert placebo pill, matching active treatment pill.
Drug: Placebo
Matched placebo capsules to the intervention arm

Primary Outcome Measures :
  1. Bladder Capacity [ Time Frame: 10 weeks ]
    Urodynamic bladder capacity

Secondary Outcome Measures :
  1. 3 Day Voiding Diary [ Time Frame: 10 weeks ]
    The 3 day voiding diary is a simple patient maintained record of fluid intake, voided volume and incontinence episodes. This will be used to assess number of episodes of urgency incontinence, urinary frequency, longest time between voids, functional capacity, and mean voided volume

  2. 24hr Urinary Pad Weights [ Time Frame: 10 weeks ]
    This will determine the amount of urinary incontinence that occurs over a 24hr period.

  3. Quality of Life (Bladder Specific) [ Time Frame: 10 weeks ]
    The Short Form-Qualiveen is a urinary specific quality of life measure developed and studied specifically for neurogenic bladder patients; validity, reliability and responsiveness have been established.

  4. Quality of Life (Incontinence) [ Time Frame: 10 weeks ]
    The I-QOL is an incontinence specific quality of life tool that has been shown to be a valid, reliable and responsive measurement among patients with neurogenic bladder dysfunction

  5. Patient Reported Outcome Measure-NBSS [ Time Frame: 10 weeks ]
    The Neurogenic bladder symptom score (NBSS) is a symptom specific measure of urinary symptoms developed for patients with neurogenic bladder dysfunction with demonstrated validity and reliability. Minimum score is 0, maximum score is 74. Higher score is worse neurogenic bladder symptoms.

  6. Patient Perception of Bladder Condition [ Time Frame: 10 weeks ]
    The patient perception of bladder condition is a commonly used measure in the assessment of oral medications for the treatment of overactive bladder symptoms

  7. Adverse Events [ Time Frame: 10 weeks ]
    Adverse events will be monitored passively. They will be actively monitored for hypertension, tachycardia, and urinary retention.

  8. Secondary Urodynamic Characteristics: Maximum Detrusor Pressure [ Time Frame: 10 weeks ]
  9. Secondary Urodynamic Characteristics: Volume at Maximum Detrusor Pressure [ Time Frame: 10 weeks ]
  10. Secondary Urodynamic Characteristics: Bladder Sensation [ Time Frame: 10 weeks ]
  11. Secondary Urodynamic Characteristics: Bladder Compliance [ Time Frame: 10 weeks ]
  12. Secondary Urodynamic Characteristics: Volume at First Detrusor Overactivity [ Time Frame: 10 weeks ]

Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion criteria:

  • Diagnosis of traumatic or nontraumatic suprasacral spinal cord injury (SCI) or multiple sclerosis (MS, based on a neurologist assessment and/or the McDonald criteria)(28)
