About this study

Official title: Investigating the Noradrenergic System in the Living Human Brain With Hybrid Molecular Functional Imaging

The main goal of this research proposal is to provide, for the first time in humans, a wider understanding of the role of the noradrenergic system both in health and illness (Parkinson's disease) through the use of a newly developed radiotracer (11Carbon [11C]Yohimbine) visualizing alpha-2 (α2) adrenergic receptors (AR) combined with cutting-edge technology, the hybrid positron emission tomography (PET)/magnetic resonance imaging (MRI) scanner. The secondary aim of this study will be to determine whether the expected age- and Parkinson's disease (PD)-related changes in the noradrenergic system are paralleled by changes in neuropsychological performances (such as cognitive, motor and/or olfactory abilities).

What participants receive

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

  • The role of the noradrenergic system across the life span (Healthy Subjects)Other

    A sample (n=90) of balanced distribution of healthy males and females within a continuous segment of the adult life span from 20 to 80 years old will be recruited, with approximately 7 males and 7 females subjects for each decade of age. Each participant will undergo 1) a neuropsychological examination, 2) an olfactory screening and 3) a 90 min 11C-Yohimbine positron emission tomography (PET)/magnetic resonance imaging (MRI) scan in a resting state.

  • The role of the noradrenergic system across the life span (Parkinson's Disease Subjects)Other

    Three groups of Parkinson Disease (PD) patients (each of them n=15) will be studied according to the duration and stage of the disease: early stage (the same group in Task 2); mid stage (5-7 years of disease duration; Hoehn and Yahr in Off 2-3); late stage (7-10 years of disease duration; Hoehn and Yahr in Off 3-4).

What is being measured

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

  1. Positron Emission Tomography (PET) and Magnetic Resonance Imaging (MRI) measures

    Derived from the Positron Emission Tomography (PET) data, the binding potentials will be calculated using compartmental modelling techniques. Derived from the Magnetic Resonance Imaging (MRI) data.

    Measured: Day 1 -180 minutes

Secondary outcomes (14)
  1. Global Cognitive Assessment

    Measured with Montreal Cognitive Assessment. Outcome measure is between 0 and 30. A score of 26 or over is considered to be normal.

    Measured: Day 2 - 10 minutes

  2. Memory Assessment

    Measured with the 16-item Free and Cued Recall test. Outcome measure is the total immediate recall which is the sum of free and cued recall.

    Measured: Day 2 - 20 minutes

  3. Working Memory Assessment

    Measured with the Digit Span Memory test. Outcome measure is the total number of items correctly repeated.

    Measured: Day 2 - 20 minutes

  4. Executive Functioning

    Measured with the Trail Making test. Unit of measure is first seconds to perform the test, which will be converted in a percentile score and then number of errors made during the test.

    Measured: Day 2 - 20 minutes

  5. Planning Functioning

    Measured with the Tower of London test. Outcome measure is the total correct and total moves score.

    Measured: Day 2 - 20 minutes

  6. Visuo-spatial Assessment

    Measured by the Visual Object and Space Perception Battery. The study will use a selection of theses tests : incomplete letters (outcome measure is between 0 and 20; cut-off score = 16) and position discrimination (outcome measure is between 0 and 10; cut-off score = 7)

    Measured: Day 2 - 20 minutes

  7. Depression Evaluation

    Measured by the Beck Depression Inventory-II Questionnaire. Outcome measure is between 0 and 20 with a cut-off score = 13. A score higher than 14 indicates the presence of depression.

    Measured: Day 2 - 10 minutes

  8. Anxiety Evaluation

    Measured by the State-Trait Anxiety Inventory (STAI) form Y questionnaire. Outcome measure is between 20 and 80, with higher scores correlating with greater anxiety.

    Measured: Day 2 - 10 minutes

  9. Praxic Abilities

    Measured by the Mahieux Praxic test. Outcome measure is between 0 and 23.

    Measured: Day 2 - 10 minutes

  10. Day time sleepiness evaluation

    Measured by the Epworth Sleepiness Scale Questionnaire. Outcome measure is between 0 and 24 with a score between 0-8 indicating normal Daytime sleepiness, a score between 9-14 indicating mild sleep deficiency and a score above 15 an excessive daytime sleepiness.

    Measured: Day 2 - 5 minutes

  11. Sleep Quality

    Measured by the Pittsburgh Sleep Quality Index (PSQI). Outcome measure is between 0 and 21 with 0 indicating no sleep problem and 21 major sleep disorder.

    Measured: Day 2 - 5 minutes

  12. Olfactory assessment : odor detection

    The odor detection capability will be evaluated using a phenyl-ethyl alcohol (PEA) test. In this experiment, the detection threshold is obtained using a "staircase" procedure. Outcome measure is between 0 and 16 with higher score indicating better performance.

    Measured: Day 2 - 30 minutes

  13. Olfactory assessment: odor discrimination

    Odor discrimination capacity will be assessed by asking the participant to smell three bottles (two bottles contain the same odor, and the third contains a different smell). The test includes 16 triplets of odorous substances. Outcome measure is between 0 and 16 with higher score indicating better performance.

    Measured: Day 2 - 30 minutes

  14. Olfactory assessment : odor identification

    The odor identification capacity will be estimated by the European test of olfactory capacities (ETOC), a test based on 16 identifications. Outcome measure is between 0 and 16 with higher score indicating better performance.

    Measured: Day 2 - 30 minutes

Questions about this trial

What is this clinical trial studying?

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 15 inclusion and 6 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: status not confirmed, as of the sponsor's last update on 24 Jun 2019. 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 France. 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?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Chloé Laurencin, MD (4.72.11.80.22 ext. 33, chloe.laurencin@chu-lyon.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Positron Emission Tomography (PET) and Magnetic Resonance Imaging (MRI) measures (time frame: Day 1 -180 minutes). 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 24 Jun 2019.
