Inclusion Criteria

Subjects must have a confirmed and documented RRMS diagnosis as defined by the Revised McDonald criteria, with relapse onset disease or a relapsing-remitting disease course.
Subjects must be ambulatory with an Kurtzke EDSS score of 0-5.5 at both Screening and Baseline (randomization) visits.
Subjects must be in a stable neurological condition, relapse-free and free of any corticosteroid treatment (intravenous [IV], IM and/or per os [PO]) or adrenocorticotrophic hormone (ACTH), 60 days prior to randomization.
Subjects must have experienced at least 1 documented relapse in the last year prior to randomization or 2 relapses in the last 3 years prior to randomization.
Subjects must be between 18 and 55 years of age at screening, inclusive.
Women of child-bearing potential must practice an acceptable method of birth control until 30 days after the last dose of treatment was administered (acceptable methods of birth control in this study include: surgical sterilization, intrauterine devices, oral contraceptive, contraceptive patch, long-acting injectable contraceptive or double-barrier method [condom or diaphragm with spermicide]).
Subjects must be able to sign and date a written informed consent prior to entering the study.
Subjects must be willing and able to comply with the protocol requirements for the duration of the study.
other criteria may apply, please contact the investigator for more information

Exclusion Criteria:

Subjects with progressive forms of MS.
Subjects with Neuromyelitis Optica (NMO).
Use of experimental or investigational drugs and/or participation in drug clinical studies within 6 months prior to Baseline visit (randomization).
Use of immunosuppressive agents, or cytotoxic agents, including cyclophosphamide and azatioprine within 12 months prior to Baseline.
Natalizumab (Tysabri®) if given more than 6 months prior to randomization AND the subject is John Cunningham (JC) virus antibody test negative at Screening.
Previous use of Rituximab, ocrelizumab, or ofatumumab is allowed if the B cell count (CD19) is higher than 80 cells /μL.
Previous treatment with glatiramer acetate (Copaxone®e), fingolimod (Gilenya®), BG-12 (Tecfidera), Teriflunomide (Aubagio®) or intravenous immunoglobulin (IVIG) within 2 months prior to Baseline.
Use of mitoxantrone (Novantrone) within 5 years prior to Screening. Use of mitoxantrone (Novantrone) >5 years before screening is allowed in subjects with normal ejection fraction and who did not exceed the total lifetime maximal dose.
Chronic (more than 30 consecutive days or monthly dosing, eg, with the intent of MS disease modification) systemic (IV, IM or PO) corticosteroid treatment within 2 months prior to Baseline.
Previous use of cladribine.
Previous use of laquinimod or Avonex® IM.
Treatment with other Interferon-β (either 1a subcutaneous [SC] or 1b SC) within 60 days before baseline (earlier treatment will be allowed if the reason for discontinuation was not treatment failure or for Interferon-β related safety reasons. This decision will be taken by the investigator).
Previous total body irradiation or total lymphoid irradiation.
Previous stem cell treatment, autologous bone marrow transplantation, or allogenic bone marrow transplantation.
Acute infection within 2 weeks prior to Baseline visit.
