Investigating Central Mechanisms of Overactive Bladder in Adults With Parkinson's Disease

August 16, 2021 updated by: Pinky Agarwal, MD, EvergreenHealth

Case-control Study Investigating Central Mechanisms of Overactive Bladder in Adults With Parkinson's Disease and Overactive Bladder and Adults With Parkinson's Disease Only

This study investigates the central mechanisms of Overactive Bladder (OAB) in Patients with Parkinson's Disease (PD).

The plan is to enroll 10 adults with Parkinson's disease and Overactive bladder (PD + OAB) and 10 adults with Parkinson's disease only (PD). Both groups will undergo fMRI (functional MRI).

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Detailed Description

Overactive bladder (OAB) is a physical problem that causes strong urges to urinate, frequent urination, and sometimes urinary incontinence (accidental loss of urine control) commonly in patients with Parkinson' disease (PD) severely impacting their quality of life.

Unfortunately OAB in adults with PD is difficult to treat. This is largely because the mechanisms underlying OAB in adults with PD are not known. Recent functional MRI (fMRI) studies suggest that certain areas of the brain have an important role in OAB. Blood oxygenation level dependent (BOLD) fMRI is an imaging technique in which neural activity of a region of the brain can be measured by fluctuation in the BOLD signal. It is hoped that the findings of this study will allow the development of new treatments for adults with Parkinson's disease and overactive bladder.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

30 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Probability Sample

Study Population

10 adults with Parkinson's disease (PD) and Overactive Bladder (OAB) and 10 adults with PD only.

Description

Inclusion Criteria:

  • Diagnosis of PD by United Kingdom (UK) brain bank criteria.
  • PD patients with and without OAB as per bladder questionnaire.
  • No change in PD medications after screening, with no dose changes during the study, except that pro re nata (PRN) doses of carbidopa/levodopa will be allowed to address periodic worsening of parkinsonian symptoms.
  • Patient willing and able to complete study questionnaires.
  • Use of other medication that could influence bladder function, will be permitted as long as the dose is stable during the study.
  • Patient expects to have valid health insurance for the duration of the study period.

Exclusion Criteria:

  • Women who are breast-feeding, pregnant or have the potential to become pregnant during the course of the study (fertile and unwilling/unable to use effective contraceptive measures).
  • Cognitive deficits that in the opinion of the investigator would interfere with the subject's ability to give informed consent or perform study testing.
  • Evidence of Urinary Tract Infection (UTI) at screening.
  • Bladder pain or history of chronic inflammation such as interstitial cystitis, recurrent UTIs, bladder stones, bladder obstruction, previous pelvic radiation therapy, or previous or current malignant disease of the pelvic organs.
  • Adults who have an interstim device in place.
  • Claustrophobia, occupational risk for ferrous metal in the eye, or having an implantable medical device or foreign body precluding fMRI (e.g. cardiac pacemaker, metallic fragment, orthopedic hardware).
  • Intravesical botulinum toxin treatment within the previous six months of screening.
  • Use of indwelling catheter or self-catheterization.
  • Any other serious and/or unstable medical condition

Design Details

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Comparison of perfusion activity in the Limbic System
Time Frame: 1 hour functional Magnetic Resonance Imaging (fMRI)
Comparison of the perfusion activity in the limbic system between subjects with Parkinson's Disease and Overactive Bladder and Parkinson's disease only using Blood Oxygenation Level Dependent (BOLD) functional Magnetic Resonance Imaging (fMRI) contrast maps. It will be performed at the second visit.
1 hour functional Magnetic Resonance Imaging (fMRI)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Determination on the relationship of perfusion activity in the limbic system and anxiety.
Time Frame: 1 hour functional Magnetic Resonance Imaging (fMRI) - 10 Minutes questionnaire.
Determination of the relationship of perfusion activity in the limbic system and anxiety scores (using Zung's Self-rating Anxiety Scale (SAS)) in subjects with Parkinson's Disease and Overactive Bladder.
1 hour functional Magnetic Resonance Imaging (fMRI) - 10 Minutes questionnaire.

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
