Patients suffering relapsing- remitting multiple sclerosis will be investigated in this study, with an EDSS score less or equal to 4.0. Patients must be older than 18 years old. There must not be any clinical evidence of an MS relpase within the 3 months prior to inclusion.

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: Cerebral perfusion is globally decreased in patients with Multiple Sclerosis (MS) and might contribute to progressive axonal degeneration, cognitive decline and fatigue. In this placebo-controlled, double-blind, randomized trial with the endothelin-1 antagonist bosentan, we want to explore whether pharmacological restoration of cerebral blood flow (CBF) in patients with MS can improve axonal metabolism and clinical disability.;Secondary Objective: Not applicable.;Primary end point(s): N-acetyl aspartate (NAA) levels after restoring the cerebral blood flow (CBF) with the endothelin-1 antagonist.;Timepoint(s) of evaluation of this end point: Before the start of the study (day 0). At the end of the study (this is at day 28 +/- 2 days) | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): - Effects on the clinical disability and fatigue in MS patients - Effects on biomarkers of multiple sclerosis (serum neurofilament light chain) wich can be used as a marker of axonal damage.;Timepoint(s) of evaluation of this end point: Before the start of the study (day 0). At the end of the study (this is at day 28 +/- 2 days) | — |
