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

NCT02904876

TerminatedPhase 4

Sponsor: University Hospital, Strasbourg, France

Conditions: Multiple Sclerosis

Interventions: Diffusion Magnetic Resonance Imaging at 6 months

Countries: France

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.
