Title: Double-blind, Randomized, Placebo-controlled, Parallel-group, Multicenter Study Evaluating the Safety, Tolerability and Effect on MRI Lesion Parameters of FTY720 vs Placebo in Patients With Relapsing Multiple Sclerosis Including 18 Month Extension Phase
Brief Summary: This study evaluated the safety, tolerability and effect on MRI lesion parameters of FTY720 in patients with relapsing multiple sclerosis.


Options:
A: Core Study

Inclusion Criteria:

* Diagnosis of relapsing multiple Sclerosis (MS)
* Patients with at least two documented relapses in the previous 2 years or one documented relapse in the last year
* Patients with an Expanded Disability Status Scale (EDSS) score of 0-6

Extension Study

* A positive Gd-enhanced MRI scan at screening (in case the first MRI scan obtained at screening was negative, a second scan could have been obtained 1 month later)
* Neurologically stable with no evidence of relapse within 30 days prior to randomization,or during the Screening and Baseline periods.
* Female patients either post-menopausal, surgically incapable of bearing children, or practicing an acceptable method of birth control. Females of childbearing potential with a negative pregnancy test at baseline prior to entry into the treatment period.

Exclusion Criteria:

Core Study

* Patients with other chronic disease of the immune system, malignancies, pulmonary or heart disease, etc
* Pregnant or nursing women

Extension Study

* Patients who had permanently discontinued study drug prior to the Month 6 visit of the core study
* Patients with diabetes mellitus (to reduce the risk of ME), and therefore ongoing patients with diabetes mellitus or who developed diabetes mellitus were discontinued from the study)

Other protocol-defined inclusion/exclusion criteria may apply
B: Inclusion Criteria:

1. Subjects must have a confirmed and documented MS diagnosis as defined by the Revised McDonald criteria with a relapsing-remitting disease course.
2. Subjects must be ambulatory with an EDSS score of 0-5.5 in both screening and baseline visits.
3. Subjects must be in a relapse-free, stable neurological condition and free of corticosteroid treatment \[intravenous (IV), intramuscular (IM) and/or per os (PO)\] or ACTH 30 days prior to screening (month -1) and between screening and baseline (month 0) visits.
4. Subjects must have experienced one of the following:

   At least one documented relapse in the 12 months prior to screening, or At least two documented relapses in the 24 months prior to screening, or One documented relapse between 12 and 24 months prior to screening with at least one documented T1-Gd enhancing lesion in an MRI performed within 12 months prior to screening.
5. Subjects must be between 18 and 55 years of age, inclusive.
6. Women of child-bearing potential must practice an acceptable method of birth control.
7. Subjects must be able to sign and date a written informed consent prior to entering the study.
8. Subjects must be willing and able to comply with the protocol requirements for the duration of the study

Exclusion Criteria:

1. Subjects with progressive forms of MS.
2. Use of experimental or investigational drugs, and/or participation in drug clinical studies within the 6 months prior to screening.
3. Use of immunosuppressive (including Mitoxantrone and Fingolimod) or cytotoxic agents within 6 months prior to the screening visit.
4. Use of natalizumab (Tysabri®) or any other monoclonal antibodies within 2 years prior to screening.
5. Use of cladribine within 2 years prior to screening.
6. Previous treatment with immunomodulators (including IFNβ 1a and 1b, and IV Immunoglobulin (IVIg) within 2 months prior to screening.
7. Previous use of GA or any other glatiramoid.
8. Chronic (more than 30 consecutive days) systemic (IV, PO or IM) corticosteroid treatment within 6 months prior to screening visit.
9. Previous total body irradiation or total lymphoid irradiation.
10. Previous stem-cell treatment, autologous bone marrow transplantation or allogenic bone marrow transplantation.
11. Pregnancy or breastfeeding.
12. Subjects with a clinically significant or unstable medical or surgical condition that would preclude safe and complete study participation, as determined by medical history, physical exams, ECG, abnormal laboratory tests and chest X-ray. Such conditions may include hepatic, renal or metabolic diseases, systemic disease, acute infection, current malignancy or recent history (5 years) of malignancy, major psychiatric disorder, history of drug and/or alcohol abuse and allergies that could be detrimental according to the investigator's judgment.
13. A known history of sensitivity to Gadolinium.
14. Inability to successfully undergo MRI scanning.
15. A known drug hypersensitivity to Mannitol.

* Must have an EDSS score between 0.0 and 5.0.
* Must have experienced at least 2 relapses that have been medically documented within the last 3 years with at least one occurring in the last 12 months

Key Exclusion Criteria:
