About this study

Official title: A Double Blind, Randomized Placebo Controlled Trial Evaluating the Urodynamic and Clinical Efficacy of Mirabegron Among Neurogenic Bladder Patients

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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Bladder Capacity

    Urodynamic bladder capacity

    Measured: 10 weeks

Secondary outcomes (12)
  1. 3 Day Voiding Diary

    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

    Measured: 10 weeks

  2. 24hr Urinary Pad Weights

    This will determine the amount of urinary incontinence that occurs over a 24hr period.

    Measured: 10 weeks

  3. Quality of Life (Bladder Specific)

    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.

    Measured: 10 weeks

  4. Quality of Life (Incontinence)

    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

    Measured: 10 weeks

  5. Patient Reported Outcome Measure-NBSS

    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.

    Measured: 10 weeks

  6. Patient Perception of Bladder Condition

    The patient perception of bladder condition is a commonly used measure in the assessment of oral medications for the treatment of overactive bladder symptoms

    Measured: 10 weeks

  7. Adverse Events

    Adverse events will be monitored passively. They will be actively monitored for hypertension, tachycardia, and urinary retention.

    Measured: 10 weeks

  8. Secondary Urodynamic Characteristics: Maximum Detrusor Pressure

    Measured: 10 weeks

  9. Secondary Urodynamic Characteristics: Volume at Maximum Detrusor Pressure

    Measured: 10 weeks

  10. Secondary Urodynamic Characteristics: Bladder Sensation

    Measured: 10 weeks

  11. Secondary Urodynamic Characteristics: Bladder Compliance

    Measured: 10 weeks

  12. Secondary Urodynamic Characteristics: Volume at First Detrusor Overactivity

    Measured: 10 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing Mirabegron in people with Urinary Bladder, Neurogenic, run by London Health Sciences Centre Research Institute OR Lawson Research Institute of St. Joseph's at 5 sites in Canada.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 38 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 5 Feb 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 5 sites in Canada. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 7 Jan 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Bladder Capacity (time frame: 10 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 Feb 2019.
