Trial summary

It is difficult to determinate prognostic criteria of Multiple Sclerosis with conventional MRI insofar as physiopathology is not well-known: the precise sequences of events leading to plaque formation and axonal injury are still not completely understood. Read more about this study

About this study

It is difficult to determinate prognostic criteria of Multiple Sclerosis with conventional MRI insofar as physiopathology is not well-known: the precise sequences of events leading to plaque formation and axonal injury are still not completely understood.

Some elements involved in plaque formation can be studied thanks to MR techniques (cerebrospinal fluid and periveinular spaces, neuronal injury, microglia, and cerebral microcirculation's dysfunction).

This study aims at giving a better understanding of MS plaques' physiopathology, using data from modern MRI through a longitudinal followed up with weakly MR 3T examination.

Read the detailed description

The objective of this work are:

  • study weakly development of the active MS plaque with multimodal MRI parameters using advanced MRI techniques: Veinography/3D FLAIR, Diffusion (CDA), Perfusion (CBV, CBF, MTT) MR Spectroscopy (NAA, myo-inositol, choline, lactate…) and enhanced 3DT1 sequences.
  • define prognostic markers of MS aggressiveness ("black holes")
  • Study development of MS plaque around venous structures.

What participants receive

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

  • 3T MR scannerProcedure or surgery

    The follow-up will be scheduled for one year; it will consist in a weekly MR examination during the first two months, and subsequently on the 6th and the 12th months.

    We will perform for each MRI exploration an intravenous injection of contrast agents: gadobutrol (gadovist 1,0 mmol/ml) which is a stable agent with a cyclic structure. This agent is few responsible for NFS, given their low capacity to liberate gadolinium GD3+ in tissues.

    The same imaging protocol will be performed for each MR examination. Evaluation of creatinemia will be used before inclusion and during the 1st, 3rd, 5th, 7th, 9th, and the 10th MRI examination. Thus we will take advantage of catheter to perform the creatinemia blood test and to reduce the discomfort produced by the injection.

What is being measured

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

  1. Modification of MR parameters before and after the blood brain barrier disruption observed in newly enhancing lesion in MS.

    Measured: each week for 2 months, at 6 month and at 12 month

Secondary outcomes (2)
  1. Predictive scorers of plaque transformation in "black-holes", which correspond with a pejorative evolution of accurate lesions, also defined by a focal destruction of cerebral tissue.

    Measured: each week for 2 months, at 6 month and at 12 month

  2. Relation between plaques development and cerebral venous structures.

    Measured: each week for 2 months, at 6 month and at 12 month

Questions about this trial

What is this clinical trial studying?

A study testing 3T MR scanner in people with Lesions and Multiple Sclerosis, run by Hospices Civils de Lyon 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?

The sponsor lists 4 inclusion and 5 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 21 Jun 2013. 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?

Modification of MR parameters before and after the blood brain barrier disruption observed in newly enhancing lesion in MS. (time frame: each week for 2 months, at 6 month and at 12 month). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00861172, which also lists 1 linked publication.

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 21 Jun 2013.
