Inclusion Criteria:

• Able to provide signed, written informed consent to participate in the study
• 18-55 years of age.
• Definite diagnosis of MS according to the 2010 revisions of the McDonald diagnostic criteria for MS [Polman, 2011].
• Subjects do not have any manifestation of another type of MS other than RRMS.
• Subjects must have a relapsing-remitting course of disease with at least one of the following prior to screening:
• At least one confirmed relapse within the previous year or
• At least two confirmed relapses within the previous 2 years or
• At least one relapse in the previous 2 years, with a GdE brain lesion on an MRI scan in the past year.
• Expanded Disability Status Scale (EDSS) score of 0-5.5 (inclusive) at screening.
• Neurologically stable with no evidence of relapse for at least 30 days prior to start of Screening and during the Screening Phase (subjects who relapse during the screening Phase can be re-screened, once the relapse has resolved).
• A female subject is eligible to enter the study if she is:
• Of non-childbearing potential
• Of childbearing potential and NOT pregnant or nursing, has a negative serum pregnancy test at screening, and agrees to one of the following:
• Complete abstinence from intercourse for the period from consent into the study until 6 months after the last dose of investigational product; or,
• Consistent and correct use of one of the following acceptable methods of birth control for the period from consent into the study until 6 months after the last dose of investigational product:

Oral contraceptives (either combined or progesterone only) Injectable progesterone Levonorgestrel implants Estrogenic vaginal ring Percutaneous contraceptive patches Intrauterine device (IUD) or intrauterine system (IUS) with a documented failure rate of <1% per year Male partner sterilization (vasectomy with documentation of azoospermia) prior to the female subject's entry into the study; this male must be the sole partner for the subject Double barrier method: condom and an occlusive cap (diaphragm or cervical/vault caps) with a vaginal spermicidal agent (foam/gel/film/cream/suppository).

A female is considered "Non-childbearing potential" if she is status-post hysterectomy, status-post surgical removal of both ovaries, has current, documented tubal ligation, or is postmenopausal and >2 years without menses. Female subjects who are post-menopausal <2 years must be confirmed menopausal by Follicle Stimulating Hormone (FSH) and estradiol levels.

A female is considered "childbearing potential" if she has functional ovaries, ducts, and uterus with no impairment that would cause sterility. This includes women with oligomenorrhea (even severe), and women who are perimenopausal or who have just begun to menstruate.

• French subjects: In France, a subject will be eligible for inclusion in this study only if either affiliated to, or a beneficiary of, a social security category.

Exclusion Criteria:

• Unable to undergo MRI scans (e.g. due to pacemaker, severe claustrophobia, hypersensitivity to contrast media, or who lack adequate peripheral venous access).
• Any clinically significant brain abnormality other than MS found on MRI.
• Neurological findings consistent with Progressive Multifocal Leukoencephalopathy (PML) or confirmed PML (see Appendix 4, Section 11.4, for PML monitoring algorithm).
• Subjects whom experience a relapse during the Screening Phase. These subjects may be eligible for re-screening after consultation with GlaxoSmithKline (GSK).
• History of clinically significant Central Nervous System (CNS) trauma (e.g. traumatic brain injury, cerebral contusion, spinal cord compression) or a history or presence of myelopathy due to spinal cord compression by disk or vertebral disease.
• Prior treatment with any of the following:
• Systemic glucocorticoids or Adrenocorticotrophic hormone (ACTH) within one month prior to screening
• Receipt of a live vaccine within 6 weeks prior to screening
• Glatiramer acetate (Copaxone) or Interferon (IFN)-β (Betaferon, Betaseron, Avonex, or Rebif) within 3 months prior to screening
• Any immunomodulatory therapies, excluding glatiramer acetate or IFN-β, within 6 months prior to screening including natalizumab and fingolimod (Gilenya), immunoglobulin, or plasma exchange/plasmapheresis
• Any monoclonal antibodies at any time, other than natalizumab (Tysabri)
• Any lymphocyte-depleting therapies, including, but not limited to: cladribine, anti-Cluster of Differentiation 4 (CD4), total body irradiation, or bone marrow transplantation
• Any immunosuppressive agents, including, but not limited to: mitoxantrone, azathioprine, cyclosporine, cyclophosphamide, or tacrolimus
• Past or current history of medically significant adverse effects (including allergic reactions) from:
• Cetirizine (or equivalent)
• Paracetamol/acetaminophen
• Corticosteroids
• Known hypersensitivity to components of the investigational product.
• Past or current malignancy, except for
• Cervical carcinoma Stage 1B (cancer is present but has not spread) or less
• Non-invasive basal cell and squamous cell skin carcinoma
• Cancer diagnoses with a duration of complete response (remission) >5 years
• A history of hematologic malignancy excludes a subject from participation, regardless of response.
• Electrocardiogram (ECG) showing a clinically significant abnormality at Screening or showing an average QT interval for heart rate corrected using Bazett's Formula (QTcB) or QT interval for heart rate corrected using Fridericia's Formula (QTcF) interval >/=450 msec (>/=480 msec for subjects with a Bundle Branch Block) over 3 consecutive ECGs.
• Significant concurrent, uncontrolled medical condition including, but not limited to, cardiac, renal, hepatic, hematological, gastrointestinal, endocrine, immunodeficiency syndrome, pulmonary, cerebral, psychiatric, or neurological disease which in the opinion of the investigator could affect the subject's safety, impair the subject's reliable participation in the trial, impair the evaluation of endpoints, or necessitate the use of medication not allowed by this protocol.
• History of severe, clinically significant CNS trauma (e.g. cerebral contusion, spinal cord compression) or a history or presence of myelopathy due to spinal cord compression by disk or vertebral disease.
• Chronic or ongoing active infectious disease requiring long term systemic treatment such as, but not limited to, chronic renal infection, chronic chest infection with bronchiectasis, tuberculosis, or active hepatitis C.

• Known history of positive serology for HIV.

• Use of an investigational drug or other experimental therapy for a condition other than MS within 4 weeks, 5 pharmacokinetic half lives or duration of biological effect (whichever is longer) prior to screening. Any prior use of an investigational drug or other experimental therapy for MS at any time should be discussed with the GSK Medical Monitor.
• Current participation in any other interventional clinical trial. Participation in a non-interventional trial requires approval of the protocol by the GSK Medical Monitor
• French subjects: the French subject has participated in any study using an investigational drug during the previous 30 days
