Title: A Phase 3, Randomized, Rater- and Dose-Blinded Study Comparing Two Annual Cycles of Intravenous Low- and High-Dose Alemtuzumab to Three-Times Weekly Subcutaneous Interferon Beta 1a (Rebif®) in Patients With Relapsing Remitting Multiple Sclerosis Who Have Relapsed On Therapy
Brief Summary: The purpose of this study was to establish the efficacy and safety of two different doses of alemtuzumab (Lemtrada™) as a treatment for relapsing-remitting multiple sclerosis (MS), in comparison with subcutaneous interferon beta-1a (Rebif®). The study enrolled participants who had received an adequate trial of disease-modifying therapies but experienced at least 1 relapse during prior treatment, and who met a minimum severity of disease as measured by magnetic resonance imaging (MRI). Participants had monthly laboratory tests and comprehensive testing every 3 months.


Options:
A: 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.
9. Patients who wouldn´t be able to perform periodic RMN explorations, patients who are not collaborative or who need anesthesia.
10. Patients with intolerance to lactose.
11. Patients with allergy to contrast used in RMN.
12. Patients with chronic kidney disease.
13. Patients in treatment with natalizumab.
B: Inclusion criteria:

Participant had completed at least 48 months of the Extension Study CAMMS03409. Signed written informed consent form.

Exclusion criteria:

Participant participating in another investigational interventional study.

The above information was not intended to contain all considerations relevant to a participant's potential participation in a clinical trial.
C: Inclusion Criteria:

* Signed informed consent form (ICF)
* Age 18 to 55 years (inclusive) as of the date the ICF was signed
* Diagnosis of MS per update of McDonald criteria
* Onset of MS symptoms (as determined by a neurologist; could be retrospectively) within 10 years of the date the ICF was signed
* Expanded Disability Status Scale (EDSS) score 0.0 to 5.0 (inclusive) at Screening
* Greater than or equal to (\>=) 2 MS attacks (first episode or relapse) occurring in the 24 months prior to the date the ICF was signed, with \>=1 attack in the 12 months prior to the date the ICF was signed, with objective neurological signs confirmed by a physician, nurse practitioner, or other Genzyme-approved health-care provider and the objective signs could be identified retrospectively
* \>=1 MS relapse during treatment with a beta interferon therapy or glatiramer acetate after having been on that therapy for \>=6 months within 10 years of the date the ICF was signed
* MRI scan demonstrating white matter lesions attributable to MS and meeting at least 1 of the following criteria, as determined by the neurologist or a radiologist: \>=9 time constant 2 (T2) lesions at least 3 millimeter (mm) in any axis; a gadolinium- (Gd-) enhancing lesion at least 3 mm in any axis plus \>=1 brain T2 lesions; and a spinal cord lesion consistent with MS plus \>=1 brain T2 lesion

Exclusion Criteria:

* Received prior therapy with alemtuzumab
* Current participation in another clinical study or previous participation in CAMMS323 (Comparison of Alemtuzumab and Rebif Efficacy in Multiple Sclerosis, CARE-MS I)
* Treatment with natalizumab, methotrexate, azathioprine, or cyclosporine in the past 6 months. Participants who received one of these medications more than 6 months before the date the ICF was signed were eligible for study entry if approval was granted by Genzyme
* Any progressive form of MS
* History of malignancy (except basal skin cell carcinoma)
* CD4 +, CD8 +, CD19 + (that is, absolute CD3 + CD4 + , CD3 + CD8 + , or CD19 + /mm 3 ) count, absolute neutrophil count less than (\<) lower limit of normal (LLN) at screening; if abnormal cell count(s) returned to within normal limits (WNL), eligibility could be reassessed
* Known bleeding disorder (for example, dysfibrinogenemia, factor IX deficiency, hemophilia, Von Willebrand's disease, disseminated intravascular coagulation, fibrinogen deficiency, or clotting factor deficiency)
* Significant autoimmune disease including but not limited to immune cytopenias, rheumatoid arthritis, systemic lupus erythematosus, other connective tissue disorders, vasculitis, inflammatory bowel disease, severe psoriasis
* Presence of anti-thyroid stimulating hormone (TSH) receptor (TSHR) antibodies (that is, above the LLN)
* Active infection or at high risk for infection
D: Inclusion Criteria:

* Male and female patients between ages 18-55 with a diagnosis of multiple sclerosis
* Patients with a relapsing-remitting disease course
* Patients with EDSS score of 0-5.5

Exclusion Criteria:

* Patients with other chronic disease of the immune system, malignancies, acute pulmonary disease, cardiac failure, etc.
