Primary Outcome Measures:
  • Number of participants with Adverse Events (AEs) and Serious Adverse Events (SAEs) [ Time Frame: Up to 6 years combining the Open-Label Extension Study 205MS303 with the initial Study 205MS301 (NCT01064401),Study 205MS203 (NCT01051349) or Study 205MS302 (NCT01462318) ]

Secondary Outcome Measures:
  • Annualized Relapse Rate (ARR) [ Time Frame: Up to 6 years combining the Open-Label Extension Study 205MS303 with the initial study 205MS301, study 205MS203 or 205MS302 ]
    Relapses are defined as new or recurrent neurological symptoms not associated with fever or infection, lasting at least 24 hours, and accompanied by new objective neurological findings upon examination by the Examining Neurologist

  • Number of participants who relapse [ Time Frame: Up to 6 years combining the Open-Label Extension Study 205MS303 with the initial study 205MS301, study 205MS203 or 205MS302 ]

    Sustained disability progression is defined as at least a 1.0 point increase on the Expanded Disability Status Scale (EDSS) from baseline EDSS ≥1.0 that is sustained for 24 weeks, or at least a 1.5 point increase on the EDSS from baseline EDSS <1.0 that is sustained for 24 weeks. The EDSS measures the disability status of people with multiple sclerosis on a scale that ranges from 0 to 10. The range of main categories include (0) =normal neurologic exam; to(5) = ambulatory without aid or rest for 200 meters; disability severe enough to impair full daily activities; to (10) = death due to MS.

    The 29-item Multiple Sclerosis Impact Scale (MSIS-29) is a disease specific patient-reported outcome measure that has been developed and validated to examine the physical and psychological impact of MS from a patient's perspective; it measures 20 physical items and 9 psychological items

  • Change in quality of life as assessed by the European Quality of Life, 5 dimensions (EQ 5D and EQ VAS) [ Time Frame: Up to 5 years during the Open-Label Extension Study 205MS303 ]
    The EQ-5D is a self-administered questionnaire consisting of 5 sets of 3 questions pertaining to specific health states (i.e.: mobility, self-care, pain, usual activities, anxiety), and a visual analog scale that records the respondent's self-rated health from 0 (worst imaginable health state) to 100 (best imaginable health state).

  • Change from baseline in direct health resource utilization (HRU) [ Time Frame: Up to 5 years during the Open-Label Extension Study 205MS303 ]

  • Change from baseline in Symbol Digit Modalities Test (SDMT) score [ Time Frame: Up to 6 years combining the Open-Label Extension Study 205MS303 with the initial study 205MS301 ]
    SDMT is a screening test for cognitive impairment. Participants are given 90 seconds in which to pair specific numbers with given geometric figures using a key. Scores range from 0 to 110 (best).

  • Change from baseline in 3-Second Paced Auditory Serial Addition Test (PASAT 3) score [ Time Frame: Up to 6 years combining the Open-Label Extension Study 205MS303 with the initial study 205MS301 ]
    The PASAT assesses auditory information processing speed. A random series of numbers from 1 to 9, inclusive, are presented and the participant is instructed to consecutively add pairs of numbers so that each number is added to the one that immediately preceded it. In the 3- second PASAT, numbers are presented at a rate of 1 every 3 seconds.
