Eligibility Criteria  ICMJE

Inclusion criteria :

  • Participants with RRMS aged from 10 years to <18 years at study entry are eligible. Participants must meet the criteria of diagnosis of MS as defined by the International Pediatric MS Study Group (IPMSSG) criteria for pediatric MS and the criteria of MS based on 2010 McDonald criteria.
  • Signed written informed consent/assent obtained from participant and participant's legal representative (parent or guardian) according to local regulations.
  • Expanded Disability Status Scale (EDSS) score of 0.0 to 5.0 (inclusive) at screening.
  • At least 2 recorded MS attacks and at least 1 MS attack (relapse) in the last year during treatment with a beta interferon therapy (IFNB) or glatiramer acetate (GA) after being on that therapy for at least 6 months, and was currently still taking the same therapy.
  • At least 1 of the following:
  • >=1 new or enlarging T2 hyperintense lesion or gadolinium enhancing lesion while on that same prior therapy (IFNB or GA), or

  • Medical, psychiatric, cognitive, or other conditions that, in the Investigator's opinion, compromise the participant's ability to understand the participant information, to give informed consent, to comply with the trial protocol, or to complete the study.
  • Major psychiatric disorder that is not adequately controlled by treatment in the opinion of the Investigator.
  • Epileptic seizures that are not adequately controlled by treatment.
  • Magnetic resonance imaging (MRI)-related conditions: conditions that could interfere with MRI acquisition and/or interpretation of MRI results (eg, claustrophobia, orthopedic implants/treatments, orthodontic treatments etc).
  • Known bleeding disorder (e.g., dysfibrinogenemia, factor IX deficiency, hemophilia, Von Willebrand's disease, disseminated intravascular coagulation, fibrinogen deficiency, clotting factor deficiency).
  • Prior history of invasive fungal infections.
  • Active infection, eg, deep-tissue infection, that the Investigator considers sufficiently serious to preclude study participation.
  • In the Investigator's opinion, participant is at high risk for infection (e.g., indwelling catheter, dysphagia with aspiration, decubitus ulcer, history of prior aspiration pneumonia or recurrent urinary tract infection).
