1.Patient with documented relapsing-remitting multiple sclerosis (RR-MS) according to revised McDonald’s criteria including MRI scan revealing lesion consistent with the diagnosis of MS.
2.Patient with unsatisfactory response to first line treatment defined as :
a.Under treatment with interferon beta-1a, interferon beta-1b, peginterferon beta-1a or glatiramer acetate for at least 12 months before randomisation;
b.With at least one relapse during the 12-months before randomisation or at least 2 relapses during the 24-months before randomisation, under treatment. Relapse is defined as a new or a worsening of an existing neurological sign lasting more than 24 hours in patients who have been stable, were improving or slowly progressing and in whom there was no infection, fever or withdrawal of steroid.
c.Taking the same treatment during 3 months prior randomisation
3.Patient with EDSS score in the range of 0 to 5.0 at the baseline visit.
4.Patient with adequate organ function
5.Male or female patient, aged 18 to 75 years, weight = 41 kg, BMI between 18 and 35 kg/m².
6.Female patient of childbearing potential (entering the study after a menstrual period and who have a negative pregnancy test), who agrees to use two highly effective methods (one for the patient and one for the partner) of medically acceptable forms of contraception during the study and for 3 months after the last treatment intake.
7.Male patients must use medically acceptable methods of contraception if your female partner is pregnant, from the time of the first administration of the study drug until three months following administration of the last dose of study drug
8.Patient able and willing to comply with study procedures as per protocol.
9.Patient able to understand, and willing to sign, and date the written informed consent form at screening visit prior to any protocol-specific procedures.
10.Patient able to understand the patient card and to follow the patient card procedures in case of signs or symptoms of severe neutropenia or severe cutaneous toxicity, during the first 2 months of treatment

1.Patients with primary progressive, secondary progressive or progressive relapsing multiple sclerosis.
2.Patient suffering from a disease other than MS that would better explain the patient’s neurological clinical signs and symptoms and/or MRI lesions.
3.Patient with MS relapse occurred within 50 days prior to randomisation and patients with previous relapse not stabilized at the time of the screening.
4.Patient treated with natalizumab, fingolimod, teriflunomide or dimethyl fumarate.
5.Patient treated within 12 weeks prior to randomisation with an approved disease modifying therapy other than interferon beta-1a, interferon beta-1b, peginterferon beta-1a, glatiramer acetate (azathioprine, cladribine, cyclophosphamide, cyclosporine, methotrexate, plasmapheresis, micophenolate mofetyl, cytapheresis,...).
6.Known allergy to gadolinium-DTPA and/or any contraindication to MRI examination.
7.Patient who previously received mitoxantrone.
8.Patient who previously received treatment with anti-lymphocyte, anti-lymphocyte monoclonal antibody (e.g. alemtuzumab) or total lymphoid irradiation.
9.Patient who had a major surgery within 4 weeks of study entry.
10.Patient presenting with cardiac disorders defined by at least one of the following conditions:
•Patient with recent cardiac history (within 6 months) of:
-Acute coronary syndrome;

-Significant ventricular arrhythmia (persistent ventricular tachycardia, ventricular fibrillation, resuscitated sudden death);
•Patient with cardiac failure class III or IV of the NYHA classification;
•Patient with severe conduction disorders which are not prevented by permanent pacing (atrio-ventricular block 2 and 3, sino-atrial block);
•Syncope without known aetiology within 3 months;
•Uncontrolled severe hypertension, according to the judgment of the investigator, or symptomatic hypertension.
11.Patient with life expectancy < 12 months.
