Title: Multicenter, Randomized, Double Blind, Clinical Trial to Compare the Clinical and Radiological Efficacy of Equivalent Doses of Methylprednisolone Administered Orally or Intravenously in Patients With Multiple Sclerosis During Relapse
Brief Summary: This is a phase IV, multicenter, randomized, double blind clinical trial. The investigators will study 48 patients with remitting relapsing multiple sclerosis (MS) experiencing moderate or severe attack receiving immunomodulatory therapy or not. Patients will be randomly assigned to one of the two groups.


Options:
A: Key Inclusion Criteria:

- Must have a body mass index of 19 to 30 kg/m2, inclusive, and minimum body weight of 45.0 kg at Screening and Day -1

Key Exclusion Criteria:

* History or positive test result at Screening for human immunodeficiency virus, hepatitis C virus antibody or current hepatitis B infection (defined as positive for hepatitis B surface antigen \[HBsAg\] and/or hepatitis B core antibody \[HBcAb\])
* History of premalignant and malignant disease including solid tumors and hematologic malignancies
* Known allergy to any interferon or any component of BIIB017
* Prior treatment with any investigational drug within the 30 days prior to Day 1, or within 5 half-lives of the drug, whichever is longer

NOTE: Other protocol defined Inclusion/ Exclusion criteria may apply.
B: Inclusion Criteria:

* Diagnosis of multiple sclerosis, in accordance with the revised McDonald criteria (2010)
* At least 2 documented clinical attacks within the last 2 years prior to screening or one clinical attack in the years prior to screening (but not within 30 days prior to screening)
* Neurologic stability for greater than or equal to (\>/=) 30 days prior to both screening and baseline
* Expanded Disability Status Scale (EDSS) score 0 to 5.5 inclusive

Exclusion Criteria:

* Primary progressive multiple sclerosis
* Disease duration of more than 10 years in patients with EDSS score less than or equal to (\</=) 2.0 at screening
* Contraindications for MRI
* Known presence of other neurological disorders which may mimic multiple sclerosis
* Pregnancy or lactation
* Requirement for chronic treatment with systemic corticosteroids or immunosuppressants during the course of the study
* History of or currently active primary or secondary immunodeficiency
* History of severe allergic or anaphylactic reactions to humanized or murine monoclonal antibodies
* Active infection, or history of or known presence of recurrent or chronic infection (for example, hepatitis B or C, Human Immunodeficiency Virus \[HIV\], syphilis, tuberculosis)
* History of progressive multifocal leukoencephalopathy
* Contraindications to or intolerance of oral or IV corticosteroids
* Contraindications to Rebif or incompatibility with Rebif use
C: Inclusion Criteria:

1. The subject must have undergone a single clinical attack.
2. The subject must have a unifocal clinical presentation.
3. The subject should be enrolled within the period of 90 days after onset of a single unifocal clinical attack (index attack).
4. There must be 2 or more cerebral lesions highly suspicious of multiple sclerosis (MS) on the screening Magnetic Resonance Imaging (MRI), measuring 6mm or more in diameter.
5. Subjects must be between the ages of 18 and 45 years inclusive.
6. Subjects must not have taken corticosteroids within the 30 days prior to the MRI at the baseline visit.
7. Subjects may be male or female. Women of child-bearing potential must practice a medically acceptable method of birth control. Acceptable methods include oral contraceptive, contraceptive patch, long-acting injectable contraceptive, or double-barrier method (condom or intrauterine device with spermicide).
8. The subjects must be willing and able to give written informed consent, prior to entering the study.

Exclusion Criteria:

1. Multifocal clinical presentation.
2. Diseases other than MS responsible for the clinical/MRI presentation. The following laboratory tests must be part of the subject's medical history for differential diagnosis of clinically isolated syndrome (CIS): erythrocyte sedimentation rate (ESR), antinuclear antibody (ANA), complement (C3, C4) and anticardiolipin IgG - IgM. In the event that the results of these tests are inconclusive, the following additional tests may be requested by the Eligibility Evaluation Committee: syphilis screening, vitamin B12 and folic acid. In the case of spinal cord CIS presentation, a spinal cord MRI is required for confirmation of diagnosis in the medical history of the subject.
3. Use of experimental or investigational drugs, including IV immunoglobulin, and/or participation in an investigational drug study within 6 months prior to study entry.
4. Use of interferon agents within 6 months prior to the screening visit.
5. Chronic corticosteroid treatment (more than 30 consecutive days) in the 6 months prior to study entry.
6. Pregnancy or breast feeding.
7. Subjects who experience a relapse between the screening (month -1) and baseline (month 0) visits.
8. Life-threatening or other clinically significant disease.
9. A medical or psychiatric condition that affects the subject's ability to give informed consent, or to complete the study, or if the subject is considered by the treating neurologist/physician to be, for any other reason, an unsuitable candidate for this study.
10. A known history of sensitivity to mannitol.
11. A known history of sensitivity to gadolinium.
12. Inability to successfully undergo MRI scanning.
D: Inclusion Criteria:

1. To have been diagnosed MS Remittent Recurrent according to Mc Donald 20052 criteria.
2. To have an EDSS between 0 and 5 before the relapse.
3. The symptoms have begun after at least one month of previous stability.
4. The symptoms have started maximum 15 days before the inclusion.
5. The patient is capable of having an adequate communication with the investigator and to carry out with the clinical trial requisites.
6. To be or not to be with allowed immunomodulatory therapy (IFN-B /AG).
7. To be capable and to be willing to ingest the medication.

Exclusion Criteria:

1. First inflammatory neurological episode (relapse).
2. Multiple sclerosis secondary progressive or primary progressive.
3. The symptoms have gone on for less than 24 hours.
4. To be in treatment or have been treated with corticoids during the three months before.
5. Patients in treatment with immunosuppressors (azathioprine, mitoxantrone, ciclofosfamide...)
6. Pregnancy or breastfeeding or women in fertile age who don't use contraceptives measurements.
7. Illnesses with contraindication treatment with corticoids.
8. Antecedents of serious adverse effects or hypersensitive to related study medication.
