About this study

Official title: Validation of Instruments for Pragmatic Clinical Trials for Overatcive Bladder

  1. Objectives \& Hypothesis Overactive bladder (OAB) affects over 10 million adults in the United States and each year substantial costs are incurred from private and public funds to test the efficacy of new and existing drugs for OAB.14 However, effectiveness and adherence data from traditional clinical trials are not generalizable to clinical practice.3, 4 In an era of limited resources and competing demands, it is essential that cost-effectiveness data from clinical trials be generalizable to the clinical world. Pragmatic clinical trials measure the effectiveness of treatments in real clinical practice, and in the full spectrum of patients that require treatment.5 Pragmatic trials require patient reported outcomes that are valid but have low patient burden.5 The conduct of pragmatic clinical trials for OAB has been limited by a lack of instruments that have demonstrable validity and reliability in the typical clinical setting Pill counts, used to measure primary outcomes in most traditional trials, are burdensome in the clinical setting.1610 The optimal instrument for measuring utility scores, general quality of life scores for cost-effectiveness analyses for OAB, is also not known.

Although poor adherence carries the potential for continued suffering for patients and wasted health care resources, there is a lack of data on the clinical and economic impact of poor adherence to treatment for OAB in real-world clinical practice. We have published preliminary data that underscores the role of adherence and utilities in the treatment of OAB. 3 Our hypothesis is that effectiveness, adherence, and utility preference scores can be measured using pragmatic patient reported instruments and that poor adherence is associated with lower effectiveness and quality of life in adults with OAB in a clinical setting. Specifically, the overriding goal of this proposal is to validate pragmatic instruments to measure effectiveness, adherence and utility preference scores and obtain preliminary data on the effect of adherence and quality of life in adults undergoing treatment for overactive bladder in a clinical setting.

Read the detailed description

Specific Aim 1: To determine the validity and responsiveness of pragmatic patient reported outcome instruments to measure clinical effectiveness, adherence and utility preference scores in adults undergoing treatment with anti-cholinergic medications for overactive bladder. We will perform a prospective cohort study of adults with OAB undergoing treatment with anti-cholinergic medication. We will compare improvement in urinary symptoms (clinical effectiveness), adherence, and change in utility preference scores from baseline to 3 months of treatment using new and existing 'gold standard' instruments. The results will be informative as to which, if any of these pragmatic instruments, is useful for measuring effectiveness, adherence, and utility preference scores in the 'real world' clinical setting.

Specific Aim 2: To use the newly validated pragmatic instruments to measure the impact of adherence on clinical effectiveness and health related quality of life in a real world clinical setting in adults undergoing treatment with anti-cholinergic medications for overactive bladder. The impact of adherence on clinical effectiveness and health related quality of life will be measured through comparisons in adults with high and low adherence to anti-cholinergic medication. This aim will corroborate the findings of aim 1 and establish if pragmatic instruments are useful in measuring outcomes of effectiveness, adherence and utility preference scores. These results will also provide preliminary data on the effectiveness of anti-cholinergic medication and the impact of adherence on clinical effectiveness and quality of life in the clinical setting.

What participants receive

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

  • ToviazDrug

    Also called Toviaz4mg and 8mg

    Means of effectiveness, adherence, and utility instruments over time will be examined to evaluate whether changes are linear from baseline to 8 weeks and 3 months. We will demonstrate the validity and responsiveness of pragmatic instruments against existing established measures (Table 3).

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Toviaz in people with Overactive Bladder, run by University of Pennsylvania at 1 site in United States.

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 4 inclusion and 9 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 10 Dec 2014. 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 United States. 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 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?

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?

Clinical effectiveness The primary outcome for clinical effectiveness will be patient reported improvement in urinary urgency at 3 months compared to before start of treatment. On two pragmatic instruments, QVD and OAB-q clinical effectiveness will be (time frame: 2.5 YEARS). 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 10 Dec 2014.
