Outcome Measures

Primary Outcome Measures :
  1. Cumulative Number of New T1 Gadolinium-Enhancing (Gd+) Lesions on Magnetic Resonance Imaging (MRI) Scan From Week 12 to Week 24 [ Time Frame: From Week 12 to 24 ]
    Cumulative Number of new T1 gadolinium-enhancing (Gd+) lesions per year on magnetic resonance imaging (MRI) scan from Week 12 to Week 24 were reported. Negative binomial (NB) regression analysis on Per protocol analysis set and imputation was applied for the missing data. Here, MS signifies multiple sclerosis.


Secondary Outcome Measures :
  1. Annualized Confirmed Relapse Rate [ Time Frame: Up to 24 weeks ]
    Relapse: occurrence of acute episode of one or more new symptoms or worsened symptoms of Multiple Sclerosis (MS), not associated with fever/infection and lasting 24 hours after stable 30 days period. Confirmed relapse: increase from baseline at least 0.5 point Expanded Disability Status Scale (EDSS) score or increase of one point in one, two or three Functional Systems (FS), excluding bowel/bladder and cerebral/mental FS. EDSS and FS scores are based on neurological examination for assessing its impairment in MS. Among eight FS, seven are ordinal clinical rating scales ranging from 0-5 or 6 with higher scale indicating overall functional impairment assessing Visual, Brain Stem, Pyramidal, Cerebellar, Sensory, Bowel/Bladder and Cerebral functions. Rating individual FS scores is used to rate EDSS with information concerning gait and use of assistance. EDSS is ordinal clinical scale ranges 0 (normal neurological examination) to 10(death due to MS)

  2. Number of Participants With First Confirmed Relapse as Assessed by Kaplan-Meier Estimate From Baseline to Week 24 [ Time Frame: Baseline to Week 24 ]
    Relapse: occurrence of acute episode of one or more new symptoms or worsened symptoms of MS, not associated with fever/infection and lasting 24 hours after stable 30 days period. Confirmed relapse: increase from baseline at least 0.5 point Expanded Disability Status Scale (EDSS) score or increase of one point in one, two or three Functional Systems (FS), excluding bowel/bladder and cerebral/mental FS. EDSS and FS scores are based on neurological examination for assessing its impairment in MS. Among eight FS, seven are ordinal clinical rating scales ranging from 0-5 or 6 with higher scale indicating overall functional impairment assessing Visual, Brain Stem, Pyramidal, Cerebellar, Sensory, Bowel/Bladder and Cerebral functions. Rating individual FS scores is used to rate EDSS with information concerning gait and use of assistance. EDSS is ordinal clinical scale ranges 0 (normal neurological examination) to 10(death due to MS). Kaplan-Meier estimate used for Outcome Measure analysis.
