About this study

Official title: Tear Analysis by Isoelectric Focusing in Clinically Isolated Syndrome as Multiple Sclerosis Criterion Among Patients With or Without Lesions at the Magnetic Resonance Imaging (Oligoclonal Profile of Tears)

This is a multicentric and prospective study for the validation of a diagnostic method in multiple sclerosis. Our hypothesis is that there is a characteristic profile of tears that can be recognized in order to help in the diagnosis of this pathology and that could possibly replace the lumbar punction which is an invasive method. Semi-automatic and automatic techniques of isoelectric focusing will be developed for analyzing data from tears. These results will help in the identification of markers of this disease.

What participants receive

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

  • tears and cerebrospinal fluid samplingProcedure or surgery

    All patients recruited in this study will undergo a cerebrospinal fluid sampling which is an invasive procedure included in the actual routine practice. In addition a sampling from eyes will be obtain using the Schirmer test to get tears from the lacrimal gland.

What is being measured

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

  1. Test of the concordance coefficient between the analysis of tears and the analysis of cerebrospinal fluid

    Test of the concordance coefficient between the analysis of tears and the analysis of cerebrospinal fluid

    Measured: two years after

Secondary outcomes (5)
  1. Diagnostic performance of isoelectric focusing of tears

    Identification of the number of patients with a typical electrophoretic profile in tears allowing the early diagnosis of a SEP-RR

    Measured: inclusion, two years after

  2. Concordance between visual and automatic reading of electrophoretic profiles

    Determination of percentage of positive and negative tests after visual and automatic reading of electrophoretic profiles

    Measured: two years

  3. Calculation of sensitivity/specificity

Questions about this trial

What is this clinical trial studying?

A study testing tears and cerebrospinal fluid sampling in people with Clinically Isolated Syndrome and Multiple Sclerosis, run by Lille Catholic University at 15 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 3 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: finished, as of the sponsor's last update on 26 Mar 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 15 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?

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?

Test of the concordance coefficient between the analysis of tears and the analysis of cerebrospinal fluid (time frame: two years after). 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 26 Mar 2024.
