Trial summary

The aim of the study is to assess the effect of continuous levodopa infusion on autonomic nervous system in patients with Parkinson's Disease (PD), blood pressure regulation and sweating. The investigators' hypothesis is that levodopa infusion may alleviate hyperhidrosis and orthostatic hypotension. Read more about this study

About this study

Official title: Effect of Duodenal Levodopa Infusion on Quality of Life and Autonomic Dysfunction in Patients With Parkinson's Disease

The aim of the study is to assess the effect of continuous levodopa infusion on autonomic nervous system in patients with Parkinson's Disease (PD), blood pressure regulation and sweating. The investigators' hypothesis is that levodopa infusion may alleviate hyperhidrosis and orthostatic hypotension.

Read the detailed description

Parkinson's disease (PD) is one of the most common neurodegenerative disorders with increasing prevalence because of aging population. The main symptoms include rigidity, hypokinesia, tremor and impaired balance, but the disease also causes autonomic dysfunction. Motor fluctuations are common treatment related problems in PD, around 50-70% of patients treated with levodopa finally develop motor fluctuations. Continuous duodenal levodopa infusion has been effective in the treatment of motor dysfunction in advanced PD. However, little is known of its effects on autonomic nervous system.

What participants receive

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

  • Levodopa infusionDrug

    Also called Duodopa

    Naso-duodenal infusion line is inserted in fluoroscopy control. Levodopa infusion is then tested approximately 5 days. If patient responds favorably to the treatment, PEG-infusion line is inserted in gastroscopy control and patient is followed in hospital for 2 to 4 days to ensure stability of the infusion line. The dosage is individually adjusted, starting dose is estimated from earlier oral levodopa dose.

What is being measured

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

  1. Orthostatic blood pressure change

    Measured: Before levodopa infusion, after 3-5 days of levodopa infusion and 2 months after levodopa infusion was started

Secondary outcomes (3)
  1. Sweating measured by evaporimeter

    Measured: Before levodopa infusion, after 3-5 days of levodopa infusion, 2 months after levodopa infusion was started

  2. Autonomic nervous system symptoms questionnaire (NMSS)

    Measured: Before levodopa infusion and 2 months after levodopa infusion was started

  3. Quality of life questionnaire (PDQ-39)

    Measured: Before levodopa infusion and 2 months after levodopa infusion was started

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Levodopa infusion in people with Parkinson's Disease, run by University of Helsinki at 1 site in Finland.

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 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: finished, as of the sponsor's last update on 24 Feb 2011. 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 Finland. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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?

Orthostatic blood pressure change (time frame: Before levodopa infusion, after 3-5 days of levodopa infusion and 2 months after levodopa infusion was started). 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 Feb 2011; AzTrials last refreshed its copy on 8 Nov 2026.
