About this study
Official title: Open-Label Safety And Dose Conversion/Determination Study of OROS® Oxybutynin Chloride for Urge Urinary Incontinence
The purpose of this study is to is to evaluate the safety and efficacy of OROS® oxybutynin chloride in patients being treated for urge urinary incontinence. Oxybutynin is an antispasmodic, anticholinergic medication for the treatment of the symptoms of overactive bladder.
Read the detailed description
Urinary incontinence refers to the involuntary loss of urine in sufficient amounts to be considered a social or health problem. It is under-reported and under-treated as patients are often ashamed and embarrassed to discuss their condition and clinicians may also fail to ask patients about incontinence. This is a multi-center, open-label study including dose conversion and dose determination to evaluate the safety of OROS® oxybutynin chloride at a clinically acceptable dose. There are three study periods: Run-in, Dose Conversion/Determination, and Maintenance. During the 1-week Run-in Period, baseline incontinence, urinary frequency, and health related quality-of-life data are collected. During the Dose Conversion/Determination Period, any previous urge urinary incontinence medications are discontinued and each patient is started on OROS® oxybutynin chloride. The dose is titrated to a clinically acceptable dose in 5-mg increments at 7 ± 3 day intervals to a possible maximum dose of 30 mg/day. The clinically acceptable dose is defined as either the minimum effective dose (i.e., the dose at which the patient has no incontinent episodes for the last 2 days of the dosing interval) or the dose providing the best balance between symptomatic improvement and side effects. Patients taking immediate-release oxybutynin at enrollment started dose titration on OROS® oxybutynin chloride at a dose equal to their immediate-release oxybutynin dose; all others started at 5 mg per day OROS® (oxybutynin chloride). After the clinically acceptable dose is established, the patient continues for an additional week at that dose to confirm that it is appropriate. Then the patient enters the 12-week Maintenance Period that evaluates whether the urge urinary incontinence reduction that is achieved by the beginning of maintenance has persisted. The primary outcome of the study is an evaluation of the safety of OROS® oxybutynin chloride. Safety assessments include the incidence of adverse events, physical examination and medical history, clinical laboratory tests, urinalysis, electrocardiograms (ECGs), vital signs, and the Physician's Anticholinergic Effects Assessment (P-ACEA), an assessment completed by the physician if severe or intolerable anticholinergic effects occur.
OROS® oxybutynin chloride (5 mg and 10 mg systems): One to five systems taken orally per day (5 mg per day to a maximum of 30 mg per day) as a single morning dose. The duration of the Maintenance Period of the study is 12 weeks.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing OROS® oxybutynin in people with Urinary Incontinence, run by Alza Corporation, DE, USA.
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 5 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 19 May 2011. Status can change between updates, so confirm with the study contact before making plans.
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 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?
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?
Incidence of adverse events; Results from Physician's Anticholinergic Effects Assessment (P-ACEA). 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 19 May 2011.
