  • A platelet count \<150 000/μL at the screening visit.
  • A history of significant bleeding event within 6 months prior to screening, according to the Investigator's judgment such as, but not limited to cerebral or gastrointestinal
  • Lymphocyte count below the lower limit of normal at Screening.
  • Recent live (attenuated) vaccine within 2 months before the first treatment visit.
  • Recent major surgery (within 4 weeks of Screening) or planned major surgery during the study.
  • The participant has received medications/treatments for MS within a specified time frame.
