What is being measured

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

  1. Change in Number of Urinary Urge Incontinence Episodes

    Mean number of urinary urge incontinence episodes measured over a 7-day diary prior to week 12. Urinary urge incontinence is defined as urinary leakage associated with a strong desire to urinate.

    Measured: Baseline, Week 2, Week 6, Week 12

Secondary outcomes (4)
  1. Change in Number of Micturitions

    Mean number of micturitions measured over a 7 day diary prior to each visit. Micturation is defined as urinating into the toilet.

    Measured: Baseline, Week 2, Week 6, Week 12

  2. Change in Number of Nocturia Episodes

    Mean number of nocturia episodes measured over a 7 day diary prior to each visit. A nocturia episode is a void (urinating into the toilet) that interrupts one's sleep.

    Measured: Baseline, Week 12

  3. Maximum Cystometric Capacity (MCC) by Urodynamic Measurements

    Maximum Cystometric Capacity (maximum volume that the bladder can hold) measured in mean milliliters

    Measured: Baseline, Week 12

  4. Incontinence Quality of Life Instrument (I-QOL)

    Measured on 3 domains; a 5-point scale (1-5) for each domain. Sum of the domain scores is normalized to a scale of 0-100 (100 = no impact of incontinence on daily activities, 0 = maximum impact of incontinence on daily activities). Mean scores presented.

    Measured: Baseline, Week 2, Week 6, Week 12

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing botulinum toxin Type A in people with Overactive Bladder and Urinary Incontinence, run by Allergan at 6 sites in 6 countries.

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 2 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 6 Nov 2013. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 6 sites in United States, Belgium, Canada, Germany, Poland and 1 more country. 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 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?

Yes. Results are posted in the registry (first posted 11 Feb 2010). 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?

Change in Number of Urinary Urge Incontinence Episodes (time frame: Baseline, Week 2, Week 6, Week 12). 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 NCT00168454, which also lists 1 linked publication.

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 6 Nov 2013; AzTrials last refreshed its copy on 31 Oct 2026.
