o At least two relapses in the last 2 years, with at least one relapse
experienced in the previous year
o At least two relapses in the last 2 years and >= 1 Gd-enhancing

Exclusion Criteria

Exclusions Related to General Health:
- Pregnancy or lactation
-Known presence or suspicion of other neurologic disorders that may mimic MS, including, but not limited to, acute disseminated encephalomyelitis, and neuromyelitis optica or neuromyelitis optica spectrum disorders and any neurologic, somatic, or metabolic condition that could interfere with brain function or normal cognitive or neurological development
- Patients that are aquaporin 4 positive and myelin oligodendrocyte glycoprotein (MOG) antibody positive are not eligible to participate in the study

- Contraindications to or intolerance of oral or IV corticosteroids, antihistaminics, or antipyretics according to the country label
- Treatment with any investigational agent within 24 weeks of screening or 5 half-lives, whichever is longer
- Previous treatment with B-cell-targeted therapies
- Any previous treatment with alemtuzumab, anti-CD4, cladribine, mitoxantrone, daclizumab, laquinimod, total body irradiation, or bone marrow transplantation
