Evaluation of Early Changes Visible to the Diffusion MRI in Response to Two Years of Treatment With Tysabri in Patients With Multiple Sclerosis

Phase 4
Terminated
Conditions
Multiple Sclerosis
Interventions
Radiation: Diffusion Magnetic Resonance Imaging at 6 months
Registration Number
NCT02904876
Lead Sponsor
University Hospital, Strasbourg, France
Brief Summary

Through this phase IV study, multicenter prospective exploratory, uncontrolled, the investigators propose to identify MRI predictive factors of treatment response, using diffusion MRI sequences, in addition to conventional sequences.

The primary objective is to study the links between changes on MRI diffusion and response to treatment with Tysabri to 2 years.

The secondary objective is to compare the evolution of diffusion MRI data with the volumetric MRI data.
