Trial summary

Overactive Bladder (OAB) is a chronic condition caused by instability of the detrusor or bladder muscle, which gives rise to symptoms of urinary urgency and often urinary incontinence. Idiopathic Detrusor Overactivity (IDO) is a subset of OAB where the cause for the bladder muscle instability is unknown. Read more about this study

About this study

Official title: Efficacy of Peri-trigonal Onabotulinumtoxin Injections in the Treatment of Refractory Idiopathic Detrusor Overactivity (IDO): A Single-blind, Randomised Controlled Trial Comparing Peri-trigonal Injections vs Injection of the Bladder Body.

Overactive Bladder (OAB) is a chronic condition caused by instability of the detrusor or bladder muscle, which gives rise to symptoms of urinary urgency and often urinary incontinence. Idiopathic Detrusor Overactivity (IDO) is a subset of OAB where the cause for the bladder muscle instability is unknown.

OAB is usually treated by conservative measures or with oral medications eg. anticholinergics. Injection of onabotulinum toxin A (onaBoNT-A) into the bladder wall is licenced in the treatment of refractory IDO where oral medications fail. The injected toxin paralyses the bladder by blocking the ability of certain (motor) nerves to communicate with the bladder muscle. As these nerves are mainly concentrated in what is known as the "body" of the bladder this is traditionally where the injections are given.

In addition to its action on motor nerves, onaBoNT-A also affects sensory nerve pathways. Recent studies show that IDO is caused by both motor and sensory nerve dysfunction, therefore injecting the "trigone", a part of the bladder where sensory nerves are particularly dense, may be of clinical benefit. Three studies comparing trigone versus trigone-sparing injection of botulinum toxin in the treatment of IDO have been carried out. One of these indicated a significant benefit in targeting the trigone and the other two did not show any difference.

Our study aims to examine if injection of onaBoNT-A into the trigone alone will provide symptom and functional improvement in patients with IDO by comparing peritrigonal injection of onaBoNT-A with the traditional method of injection which spares the trigone.

Botulinum toxin injected to bladder body, Botulinum toxin injected into trigone

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Botulinum toxin injected to bladder bodyDrug

    Also called Botulinum toxin, Onabotulinumtoxin, Botox

    arm will receive 100u of onaBoNT-A in 20x1ml aliquots (5u/ml). 20 injections will be given into the bladder wall, sparing the trigone. Injections will be given through all layers of the bladder eg suburothelially and intradetrusor. The intervention will be performed under local anaesthetic using a flexible cystoscope.

  • Botulinum toxin injected into trigoneDrug

    Also called Botulinum toxin, Onabotulinumtoxin, Botox

    Arm B will receive 100u onaBoNT-A injected into 10x1ml suburothelial peri-trigonal sites (aliquot dose 10u/ml). The procedure will be performed under local anaesthetic by flexible cystoscopy.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Botulinum toxin injected to bladder body and Botulinum toxin injected into trigone in people with Overactive Detrusor, run by Mr HD Flood at 1 site in Ireland.

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 7 inclusion and 13 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: status not confirmed, as of the sponsor's last update on 12 Dec 2013. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Ireland. 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 phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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

Are results available for this study?

Results are not available in the source record.

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

Contact H D Flood, FRCSI (e_red1@yahoo.co.uk), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Global Response Assessment (time frame: measured at 3 months following intervention). 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 12 Dec 2013.
