Drug Information available for: Cladribine

Arm Intervention/treatment
Experimental: Mavenclad® Drug: Mavenclad®
Subjects will receive Mavenclad® 3.5 milligram per kilogram (mg/kg) of body weight over 2 years, administered as 1 treatment course of 1.75 mg/kg per year.
Other Name: Cladribine

Primary Outcome Measures :
  1. Change From Baseline in Counts of Combined Unique Active (CUA) Magnetic Resonance Imaging (MRI) Lesions at Month 6 [ Time Frame: Baseline, Month 6 ]

Secondary Outcome Measures :
  1. Change From Baseline in Counts of Immune Cell Subsets at Month 3, 6, 12, 15, 18 and 24 [ Time Frame: Baseline, Month 3, 6, 12, 15, 18 and 24 ]
    Immune cell subsets will be analyzed by flow cytometry analysis.
