About this study

Official title: A Randomized, Placebo Controlled, Crossover Study to Evaluate the Effects of Tolterodine Tartrate on Urodynamic Parameters in Patients With Overactive Bladder

Being tested
tolterodine tartrate, Comparator: Placebo to tolterodine tartrate
Medical subject headings
Urinary Bladder, Overactive

What is being measured

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

  1. Change From Baseline in Maximum Cystometric Capacity at 4 Hours Post Dose 7 on Tolterodine 4 mg and Placebo

    Change from baseline in maximum cystometric capacity at 4 hours post dose 7 on tolterodine 4 mg and placebo (analysis on natural log transformed data)

    Measured: 4 hours post dose 7

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing tolterodine tartrate in people with Overactive Bladder, run by Merck Sharp & Dohme LLC.

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 3 inclusion and 16 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 22 Feb 2018. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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 19 Aug 2014). 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 From Baseline in Maximum Cystometric Capacity at 4 Hours Post Dose 7 on Tolterodine 4 mg and Placebo (time frame: 4 hours post dose 7). 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 NCT00768521, 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 22 Feb 2018.
