About this study

Official title: Influence of the Non-Ergot Dopamine Agonist Piribedil on Vigilance and Cognitive Function in Patients With Parkinson's Disease Compared to Other Oral Non-Ergot Dopamine Agonists

The purpose of this clinical trial is to investigate the effects of the non-ergot dopamine agonist piribedil on vigilance and cognitive performances in patients with Parkinson's disease in comparison with other oral non-ergot dopamine agonists.

It should be tested whether piribedil is superior to continued pramipexole or ropinirole treatment regarding improvement of reduced vigilance and cognitive performance in patients with Parkinson's disease.

Read the detailed description

Treatment of motor symptoms associated with PD by non-ergot dopamine agonists has been proven to be effective, both as monotherapy and in combination with levodopa. Non-motor symptoms like cognitive or sleep-related disorders and disturbed vigilance, however, are common in PD and can significantly worsen health and quality of life of the patient and family members. Some of these non-motor symptoms may also be caused by the antiparkinsonian medication per se. The Committee for Proprietary Medicinal Products (CPMP) initiated a review of dopamine agonists in relation to episodes of sudden onset of sleep already in 2000 which resulted in special warnings of somnolence and sudden sleep attacks in the non-ergot dopamine agonists' summary of product characteristics.

Beneficial effects of piribedil on parameters of vigilance and cognition have been described in several studies. But, as it seems, no study has been performed so far to identify such effects in the setting of a comparative study with different oral non-ergot dopamine agonists in patients with PD, and utilizing vigilance and cognitive parameters as primary and main secondary objective. The neuropsychological tests being applied in this study are validated and routinely used tests in studies investigating different aspects of attention or vigilance and cognition.

What is being measured

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

  1. The primary efficacy variable will be the 'median reaction time during the second 15 minutes (minutes 16-30)' of the subtest 'vigilance', visual test condition 'moving bar', of the Test battery for Attention Performances (TAP) at end of treatment.

    Measured: Baseline and End of Treatment

Secondary outcomes (8)
  1. Other vigilance parameters of the TAP test

    Measured: Baseline and End of Treatment

  2. Other neuropsychological tests: Test of verbal fluency (RWT), Verbal learning memory test (VLMT), Stroop test (FWIT)

    Measured: Baseline and End of Treatment

  3. Epworth Sleepiness Scale (ESS)

    Measured: Baseline and End of Treatment

  4. Parkinson's Disease Sleeping Scale (PDSS)

    Measured: Baseline and End of Treatment

  5. Unified Parkinson's Disease Rating Scale (UPDRS) subscores I to IV and total score

    Measured: Baseline and End of Treatment

  6. Parkinson's disease quality of life questionnaire (PDQ-39)

    Measured: Baseline and End of Treatment

  7. Clinical Global Impressions (CGI) (except item 3.2)

    Measured: End of Treatment

  8. Patient Global Impression (PGI)

    Measured: End of Treatment

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing piribedil and pramipexole or ropinirole in people with Idiopathic Parkinson's Disease, run by Desitin Arzneimittel GmbH at 12 sites in Germany.

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 7 inclusion and 26 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 May 2012. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 12 sites in Germany. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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?

The primary efficacy variable will be the 'median reaction time during the second 15 minutes (minutes 16-30)' of the subtest 'vigilance', visual test condition 'moving bar', of the Test battery for Attention Performances (TAP) at end of treatment. (time frame: Baseline and End of Treatment). 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 May 2012.
