About this study

Official title: Behavioural Profiling of Disease-related Cognitive and Motor Impairment With Focus on Dopaminergic Effects in Parkinson's Disease and Potential Correlation to Biomarkers.

In this project, patients with Parkinson's Disease (PD) will be characterized by measuring cognitive and motor function and relation to effect of Levodopa.

Participants will be patients with Parkinson's Disease and healthy controls. It will be investigated if there is a difference between patients with a good measured Levodopa response and with a poor measured response.

Read the detailed description

The patients with Parkinson's Disease will be included from the outpatient clinic at the Department of Neurology at Bispebjerg Frederiksberg Hospital and healthy controls will be found among relatives or volunteers through research ads.

Patients will be asked to pause dopaminergic medication for 6 half times.Then a baseline examination will be performed in the morning in a non-medicated state (OFF), using Unified Parkinson's disease rating Scale (UPDRS), the MOntreal Cognitive Assessment (MoCA) and computerized cognitive testing. Baseline screening for depression with Beck Depression Inventory (BDI) and for impulsivity with Questionnaire for Impulsive-Compulsive Disorders in Parkinson's Disease-Rating Scale (QUIP).

An acute levodopa challenge will be performed with patients receiving 200/25 mg dispersible levodopa/benserazide. After an hour UPDRS and cognitive computerized tests are repeated.

This is estimated to take about 3½ hours to complete. In healthy controls a neurological examination, BDI and MoCA will pe performed.

The UPDRS motor test is videotaped. A specialist will later evaluate the motor function blinded.

The participants will be asked to participate in the Bispebjerg Frederiksberg (BFH) BioBank, BFH-2017-114, (ISuite nr.: 05991) at Bispebjerg Frederiksberg Hospital for future research.

An exact calculation of power is difficult to calculate as the project includes a broad range of correlations.

Numeric data will be analysed using the Student's t-test (when normal distribution is met) or Wilcoxon rank sum test (when normal distribution is not met). Binary data will be analysed using the Fishers exact test.

What is being measured

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

  1. Motor improvement

    Unified Parkinson's disease rating scale, motor part (UPDRS-3) OFF medication compared to ON medication

    Measured: Baseline to end of Levodopa challenge test, approximately 3-4 hours

Secondary outcomes (1)
  1. Cognitive function

    Cognitive computer tests

    Measured: Baseline to end of Levodopa challenge test, approximately 3-4 hours

Questions about this trial

What is this clinical trial studying?

A study testing Levodopa in people with Parkinson Disease and Medication, run by University Hospital Bispebjerg and Frederiksberg 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 4 inclusion and 2 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 23 Feb 2024. 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?

Motor improvement (time frame: Baseline to end of Levodopa challenge test, approximately 3-4 hours). 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 23 Feb 2024.
