Trial summary

Parkinson disease (PD), multiple system atrophy (MSA) and progressive supranuclear palsy (PSP) are neurodegenerative disorders. PD and MSA are alpha-synucleinopathies, which are characterized by the abnormal accumulation of alpha-synuclein, while tau protein accumulates in PSP. Read more about this study

About this study

Official title: Development of Biomarkers for the Diagnosis and Prognosis of Parkinsonian Syndromes Running Head: Biomarkers in Parkinsonian Syndromes

Parkinson disease (PD), multiple system atrophy (MSA) and progressive supranuclear palsy (PSP) are neurodegenerative disorders. PD and MSA are alpha-synucleinopathies, which are characterized by the abnormal accumulation of alpha-synuclein, while tau protein accumulates in PSP. The development of biological markers for the diagnosis and prognosis in PD, MSA and PSP remains an unmet need. Such biological markers are crucial for future disease-modification and neuroprotection trials. Alpha-synuclein has a high potential for biomarker development since it constitutes the pathological hallmark feature in PD and MSA. The oligomeric alpha-synuclein seems to be particularly involved in abnormal protein aggregation in alpha-synucleinopathies.

The main objective is to compare oligomeric alpha-synuclein CSF levels between PD, MSA and PSP patients. PD and MSA patients will receive Cerebrospinal Fluid (CSF) and blood sampling at two study visits (baseline and after 12 months). Major secondary objectives are (i) to assess potential associations between the biomarker and clinical measures of disease severity and progression in MSA and PSP, and (ii) to assess the variation of the biomarker and its correlation to disease severity and progression in PD, MSA and PSP.

Read the detailed description

The differential diagnosis between Parkinson's disease, multiple system atrophy and progressive supranuclear palsy can be very difficult in early disease. PD, MSA and PSP are neurodegenerative disorders. PD and MSA belong to the alpha-synucleinopathies, which are characterized by the abnormal accumulation of alpha-synuclein. Alpha-synuclein accumulates in intraneuronal Lewy bodies in PD patients and as intracytoplasmic glial inclusions in MSA. In PSP, tau protein accumulates in neurons and glia cells while alpha-synuclein deposits are only found to a small extend.

The development of biological markers for the diagnosis and prognosis of PD, MSA and PSP remains an unmet need. Beyond guiding clinical decision-making, such biological markers are crucial for future disease-modification and neuroprotection trials.

Alpha-synuclein has a high potential for biomarker development since it constitutes the pathological hallmark feature of PD and MSA. The oligomeric alpha-synuclein fraction whose CSF levels are increased in PD seems to be particularly involved in abnormal protein aggregation in alpha-synucleinopathies.

The main objective of the study is to compare oligomeric alpha-synuclein CSF levels between PD, MSA and PSP patients. Secondary objectives are (i) to compare total alpha-synuclein levels and the index total/oligomeric alpha-synuclein between PD, MSA and PSP, (ii) to study the correlation and concordance between CSF and plasma levels of total and oligomeric alpha-synuclein, (iii) to assess potential associations between the biomarker and clinical measures of disease severity and progression and (iv) to assess the variation of the biomarker over time and its correlation to disease severity and progression.

What is being measured

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

  1. Concentration of oligomeric alpha-synuclein in cerebrospinal fluid

    Measured: at day 0 (inclusion) and one year after inclusion

Secondary outcomes (4)
  1. Total alpha-synuclein concentration in CSF, oligomeric/total alpha-synuclein ratio in CSF

    Measured: At inclusion (Day 0) and one year after inclusion

  2. Oligomeric and total alpha-synuclein concentration in plasma, oligomeric/total alpha-synuclein ratio in plasma

    Measured: At inclusion (Day 0) and one year after inclusion

  3. Alpha-synuclein levels in relation to disease severity and progression, disease duration and age

    Measured: At inclusion (Day 0) and one year after inclusion

  4. Variation of alpha-synuclein levels between first and second sampling

    Measured: At inclusion (Day 0) and one year after inclusion

Questions about this trial

What is this clinical trial studying?

An observational study of Parkinsonian Syndromes and Parkinson's Disease, run by University Hospital, Bordeaux at 3 sites in France.

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 9 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: status not confirmed, as of the sponsor's last update on 31 Mar 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites 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 Wassilios MEISSNER, Pr (wassilios.meissner@chu-bordeaux.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Concentration of oligomeric alpha-synuclein in cerebrospinal fluid (time frame: at day 0 (inclusion) and one year after inclusion). 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 31 Mar 2022.
