Trial summary

Overactive bladder induce urgency, urge incontinence, nocturia and pollakiuria. This condition is often resistant to anticholinergic drugs used as a first line treatment for this purpose. Moreover muscarinic side effects (constipation, mouth dryness) often limits the use of those treatments. Read more about this study

About this study

Official title: Efficacy and Safety of Botulinum Toxin A for the Treatment of Refractory Overactive Bladder (OAB). A Multicenter Phase II, Randomized, Double-blind, Placebo Controlled 6 Month Study . VESITOX

Overactive bladder induce urgency, urge incontinence, nocturia and pollakiuria. This condition is often resistant to anticholinergic drugs used as a first line treatment for this purpose. Moreover muscarinic side effects (constipation, mouth dryness) often limits the use of those treatments. This study is designed to evaluate the efficacy and safety of botulinum toxin A injected into the detrusor muscle to control symptoms and improve quality of life for patients resistant or intolerant to anticholinergic drugs.

What is being measured

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

  1. Number of urgency and urge incontinence episodes at 3 months after injection

    Measured: at 3 months

Secondary outcomes (12)
  1. Number of micturition episodes on micturition chart per day

    Measured: per day

  2. Mean value of volume of urine per micturition

  3. Mean delay between urgency and leakage Quality of life improvement by Iqol and EuroQol (EQ-5D)

  4. Urodynamic parameters : Volume at first contraction, volume at first desire to void, volume at urgency, maximal bladder capacity, maximal detrusor pressure

  5. Number of pads used per day

  6. Number of patients with less than 3 episodes per day of leakages by urge incontinence or urgency per day

  7. Residual volume of urine after flowmetry

  8. Maximal flow

  9. Visual analogic scale for pain for procedure

  10. Biologic modifications

  11. Ultrasound of kidneys

  12. Toxin A antibodies

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Botulinum Toxin A (Botox ) in people with Overactive Bladder, run by Assistance Publique - Hôpitaux de Paris at 1 site in France.

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 1 inclusion and 0 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: finished, as of the sponsor's last update on 17 Feb 2011. 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 France. 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. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Number of urgency and urge incontinence episodes at 3 months after injection (time frame: at 3 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00231491, which also lists 2 linked publications.

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 17 Feb 2011.
