Primary Outcome Measures:
  • Number of Participants Who Experienced First Documented Relapse [ Time Frame: Baseline up to 96 weeks (+/- 1 week) or early termination (ET) ] [ Designated as safety issue: No ]
    Documented relapse: development of new/exacerbation of existing neurological symptoms, persisting for >48 hrs and with previous period for >30 days with stable/improving condition. Exacerbation = at least (>=)1 point increase in 2 functional systems/2 points increase in 1 system,either in pyramidal, cerebral, brain-stem, sensory, bowel and bladder, visual, cerebral or other functional system or >=0.5 point increase on expanded disability status scale (EDSS) which assesses disability in 8 functional systems with overall score ranging from 0 (normal) to 10 (death due to multiple sclerosis [MS]).


Secondary Outcome Measures:
  • Number of Participants With Documented Relapses [ Time Frame: Baseline up to 96 weeks (+/- 1 week) or ET ] [ Designated as safety issue: No ]
    Documented relapse: development of new/exacerbation of existing neurological symptoms, persisting for >48 hrs and with previous period for >30 days with stable/improving condition. Exacerbation was >=1 point increase in 2 functional systems /2 points increase in 1 system, either in pyramidal, cerebral, brain-stem, sensory, bowel and bladder, visual, cerebral or other functional system or >=0.5 point increase on EDSS which assesses disability in 8 functional systems with overall score ranging from 0 (normal) to 10 (death due to MS).

  • Number of New or Enlarging Lesions on Time Constant 2 (T2) Weighted Magnetic Resonance Imaging (MRI) [ Time Frame: Final visit (96 weeks [+/- 1 week]) or ET ] [ Designated as safety issue: No ]
    Inflammatory disease activity was assessed by MRI measurement of the number of new or enlarging T2 lesions.

  • Changes in Brain Volume Measured on Magnetic Resonance Imaging (MRI) [ Time Frame: Screening , final visit (96 weeks [+/- 1 week]) or ET ] [ Designated as safety issue: No ]
    Changes in brain volume were measured as the brain parenchymal fraction using MRI scans.


Other Outcome Measures:
  • Number of Participants With Onset of Disability Progression [ Time Frame: Baseline up to 96 weeks (+/- 1 week) or ET ] [ Designated as safety issue: No ]
    Disability progression was defined as an increase, compared to baseline evaluation of >= 1.0 points on EDSS if EDSS was >= 1.0 at baseline or >=1.5 point on EDSS if EDSS was 0.0 at baseline. EDSS assesses disability in 8 functional systems with overall score ranging from 0 (normal) to 10 (death due to MS).

  • Number of Time Constant 2 (T2) Active Lesions [ Time Frame: Week 48 up to Week 96 (+/- 1 week) or ET ] [ Designated as safety issue: No ]
    Inflammatory disease activity was assessed by MRI measurement of the number of T2 active lesions.

  • Percentage of Time Constant 2 (T2) Active Scans Per Participant [ Time Frame: Baseline up to 96 weeks (+/- 1 week) or ET ] [ Designated as safety issue: No ]
    Inflammatory disease activity was assessed by MRI measurement of the percentage of T2 active scans.

  • Burden of Disease [ Time Frame: Baseline up to 96 weeks (+/- 1 week) or ET ] [ Designated as safety issue: No ]
    The burden of disease (BOD) is the total area of MS lesions (abnormal plaques) in the brain measured on Time Constant 1 (T1) or T2 weighted MRI.

  • Relapse Count [ Time Frame: Week 48 (+/- 1 week) or ET ] [ Designated as safety issue: No ]
    A relapse was defined as the development of new or the exacerbation of existing neurological symptoms or signs, in the absence of fever, persisting for more than 48 hours and with a previous period for more than 30 days with a stable or an improving condition.

  • Number of Relapse Free Participants Without Progression [ Time Frame: Baseline up to 96 weeks (+/- 1 week) or ET ] [ Designated as safety issue: No ]
    Analysis based on documented relapses (relapse: development of new/exacerbation of existing neurological symptoms, persisting for >48 hrs and with previous period for >30 days with stable/improving condition; relapse documented by exacerbation >=1 point increase in 2 functional systems/2 points increase in 1 functional system, or >=0.5 point increase on EDSS which assesses disability in 8 functional systems with overall score ranging from 0 [normal] to 10 [death due to MS]) and overall relapses (documented and undocumented relapses); undocumented relapses only fulfilled condition for relapse.

  • Number of Participants With Total Number of Reported Relapses (Documented and Undocumented Relapses) [ Time Frame: Baseline up to 96 weeks (+/- 1 week) or ET ] [ Designated as safety issue: No ]
    Documented relapses (relapse: development of new/exacerbation of existing neurological symptoms, persisting for >48 hrs and with previous period for >30 days with stable/improving condition; relapse documented by exacerbation >=1 point increase in 2 functional systems/2 points increase in 1 functional system, or >=0.5 point increase on EDSS which assesses disability in 8 functional systems with overall score ranging from 0 [normal] to 10 [death due to MS]) and undocumented relapses only fulfilled condition for relapse.

  • Relapse Severity Based on Expanded Disability Status Scale (EDSS) [ Time Frame: 96 weeks (+/- 1 week) or ET ] [ Designated as safety issue: No ]
    EDSS assesses disability in 8 functional systems. An overall score ranging from 0 (normal) to 10 (death due to MS) was calculated. EDSS progression was defined as increase by at least 1 point if last value of EDSS was equal to 5.5 and by at least 0.5 points if last EDSS was more than 5.5.

The exacerbation must be equivalent to an increase of at least 1 point in 2 functional systems or to an increase of 2 points in 1 system, either in the pyramidal, cerebellar, brain-stem, sensory, bowel and bladder, visual, cerebral or other functional system or an increase of at least half a point on the EDSS. Changes in bowel and bladder or cerebral functions should not solely be responsible for documentation of a relapse. The relapses must have been evaluated by a neurologist, retrospectively if necessary)
