About this study

AIM: Investigate wether there are differences in the parasympathetic nervous system in Parkinsons patients compared to controls.

MATERIALS AND METHODS: We use the tracer [11C]donepezil to image the parasympathetic nervous system. The Investigators will include 20 Parkinsons patients and 20 healthy controls aged 40-80 in our study. The participants will receive a careful medical examination, including a neurological examination, as part of the inclusion process. The subjects also have an MRI scan of the brain. Then PET/CT scans with [11C]donepezil are conducted - once for the upper abdominal region and once for the head region. For evaluating the function of the parasympathetic nervous system gastric emptying time, heart rate variability and salivary flow will be measured. These measureless will be correlated to the PET findings.

PERSPECTIVES: The study will potentially result in the development of a PET ligand for imaging the parasympathetic nervous system. This will have applications for research in Parkinson's disease, diabetes, heart disease and other disorders, in which the autonomic nervous system is involved

What is being measured

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

  1. Distribution volume of [11C]donepezil in internal organs

    Our primary endpoint is the distribution volume of [11C]donepezil in internal organs (including salivary glands, heart, stomach and intestines) in Parkinson's patients compared to controls.

    Measured: The distribution volume of [11C]donepezil is measured at "Day 1" by PET/CT scanning each participant. The data analysis is done when all participants have completed the study.

Questions about this trial

What is this clinical trial studying?

An observational study of Parkinson's Disease, run by Per Borghammer at 1 site in Denmark.

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 1 inclusion and 8 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 2 Jun 2015. 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 Denmark. 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.

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?

Distribution volume of [11C]donepezil in internal organs (time frame: The distribution volume of [11C]donepezil is measured at "Day 1" by PET/CT scanning each participant. The data analysis is done when all participants have completed the study.). 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 2 Jun 2015.
