Prior/Concomitant Therapy: - Treatment with any approved MS treatment at Screening. Participants may become eligible after completion of a washout period prior to acquiring any screening laboratory tests but should not be withdrawn from therapies for the sole purpose of meeting eligibility for the trial - Previous treatment with alemtuzumab, cladribine, mitoxantrone, cyclophosphamide, total body irradiation, bone marrow transplantation, and hematopoietic stem cell transplantation. For the USA only, previous treatment with daclizumab - Previous treatment with anti-CD20 B-cell-depleting therapies (e.g., rituximab, ocrelizumab, or ofatumumab) - <12 months prior to acquiring any screening laboratory tests, - =12 months prior to acquiring any screening laboratory tests, if B-cells are outside the normal range, or not back to individual baseline ± 20% (if data are available), - if discontinuation of a prior B-cell depletion therapy was motivated by safety reasons - Current or prior treatment with natalizumab (if <24 months prior to acquiring any screening laboratory tests) Prior/Concurrent Clinical Study Experience: - Participation in an investigational drug medicinal product or medical device study within 30 days before Screening or within five times the PD or PK half-life (if known), whichever is longer Diagnostic Assessments: - Positive result on human immunodeficiency virus (HIV1) and HIV2, hepatitis C, or hepatitis B - Participants with suicidal ideation or behavior within 6 months prior to Screening or participants who, in the Investigator's judgment, pose a suicidal or homicidal risk - Vaccination with a live or live-attenuated vaccine within 6 weeks prior to Day 1 |

Primary | Change From Baseline in Suicide Risk as Assessed Using the Columbia-Suicide Severity Rating Scale (C-SSRS) | The C-SSRS is an interview-based instrument used to assess baseline incidence of suicidal ideation and behavior. The assessment includes "yes" or "no" responses for 5 questions, each related to suicidal ideation (wish to be dead, non-specific active suicidal thoughts, active suicidal ideation with any methods, active suicidal ideation with some intent, active suicidal ideation with specific plan) and suicidal behavior (preparatory acts or behavior, aborted attempt, interrupted attempt, actual attempt, suicide). Numeric ratings are provided for severity of ideation (if present), from 0 to 5. A score of 0 is assigned if no suicide risk is present. A score of 1 or higher indicates suicidal ideation or behavior, with 5 being the most severe. | Day 1 to Day 169 | |
