Primary Outcome Measures :
  1. Annual Relapse Rate (AAR) [ Time Frame: up to 96 weeks from baseline ]
    ARR is the number of confirmed relapses in a year calculated based on cumulative number of relapses by patient adjusted for time-in-study by patient

Secondary Outcome Measures :
  1. Safety evaluation [ Time Frame: 96 weeks ]
    Proportion of patients with adverse events, including injection related reactions, abnormal laboratory results or vital signs as well as proportion of patients discontinuing treatment due to insufficient effectiveness or safety
