Primary Outcome Measures:
  • Safety variables will be summarized using descriptive statistics based on adverse events. [ Time Frame: Up to 6 months ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • The efficacy data regarding prevention of relapse due to MS will be estimated based on the number of relapse. [ Time Frame: During 6 month ] [ Designated as safety issue: No ]
  • Progression or aggravation to Multiple sclerosis (MS) will be identified based on the change of Expanded Disability Status Scale (EDSS) and the Magnetic Resonance Imaging (MRI) outcome. [ Time Frame: 0, 6 month ] [ Designated as safety issue: No ]
