Trial summary

The main objectives are to determine on one hand whether oligomeric alpha-synuclein levels are increased in MSA patients compared to controls and on other hand whether there is a good agreement between cerebrospinal fluid (CSF) and plasma levels. Read more about this study

Study population: Cases will be selected from cohort of 90 MSA patients referenced in Bordeaux University Hospital. Controls will be selected from patients requiring spinal tap without being affected by a neurodegenerative disorder and paired in age and gender with cases.

  • MSA patients
  • Inclusion criteria: Patients suffering from "probable" MSA according to clinical consensus criteria (Gilman et al, 2008), Age >30 Written informed consent Patient covered by the national health system
  • exclusion criteria: UMSARS IV score > 4 points Patient under tutelage Patient unable to give consent Patients receiving anticoagulants, showing abnormal coagulation on blood testing or thrombocytopenia are excluded from this study
  • Controls (patients requiring spinal tap without suffering from a neurodegenerative disorder) o Inclusion criteria: Patients not suffering from a neurodegenerative disorder and requiring a spinal tap Age >30 Written informed consent Patient covered by the national health system o exclusion criteria: Similar to MSA patients

About this study

Official title: Oligomeric Alpha-synuclein Levels as a Biomarker for Multiple System Atrophy

The main objectives are to determine on one hand whether oligomeric alpha-synuclein levels are increased in MSA patients compared to controls and on other hand whether there is a good agreement between cerebrospinal fluid (CSF) and plasma levels.

Read the detailed description

Multiple system atrophy (MSA) is a rare neurodegenerative disorder which is characterized by a variable combination of parkinsonism, cerebellar dysfunction, autonomic failure, and additional signs.

No effective treatment is available. Together with PD and Lewy body dementia, MSA belongs to a group of neurodegenerative disorders, the alpha-synucleinopathies, which are characterized by the abnormal accumulation of alpha-synuclein.

The development of biological markers for the diagnosis and prognosis in MSA 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 MSA.

The oligomeric alpha-synuclein seems to be particularly involved in abnormal protein aggregation in alpha-synucleinopathies.

The study will compare alpha-synuclein levels in CSF and plasma between patients suffering from AMS and controls who are patients requiring spinal tap without being affected by a neurodegenerative disorder. The MSA patients and controls will receive CSF and blood sampling at one study visit.

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 (CSF).

    Measured: Day 0

Secondary outcomes (3)
  1. Total alpha-synuclein concentration in CSF and oligomeric/total alpha-synuclein ratio in CSF

    Measured: Day 0

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

    Measured: Day 0

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

    Measured: Day 0

Questions about this trial

What is this clinical trial studying?

An observational study of Multiple System Atrophy (MSA), run by University Hospital, Bordeaux at 1 site in France.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

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 27 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?

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?

Concentration of oligomeric alpha-synuclein in cerebrospinal fluid (CSF). (time frame: Day 0). 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 27 Jun 2019.
