Brief Summary
This double-blind, double-dummy study will evaluate the safety and efficacy of ocrelizumab compared with fingolimod in children and adolescents with RRMS aged between 10 and \< 18 years over a flexible duration. The double-blind period will last until after the last participant randomized has completed 24 weeks.

Outcome Measures
Primary Outcomes (1)
Protocol-defined Annualized Relapse Rate (ARR)
The population-level summary is rate ratio of ARR. The ARR is calculated as the total number of protocol-defined relapses divided by the total patient-years. Protocol-defined relapse is the occurrence of new/worsening neurological symptoms attributable to multiple sclerosis (MS) and immediately preceded by relatively stable or improving neurological state for ≥ 30 days. Symptoms must persist for \>24 hours \& should not be attributable to confounding clinical factors. The new/worsening neurological symptoms must be accompanied by objective neurological worsening consistent with an increase of at least half a step on the expanded disability status scale (EDSS) score, or 2 points on one of the appropriate functional system (FS) scores, or 1 point on two or more of the appropriate FS scores. The change must affect the selected FS (i.e., pyramidal, ambulation, cerebellar, brainstem, sensory, or visual). Adjusted values were reported. OM assessed non inferiority of ocrelizumab vs fingolimod.
Up to after the last participant randomized completed 24 weeks since first study treatment administration (up to approximately 160 weeks)
Secondary Outcomes (8)
Protocol-defined ARR

Study Arms (2)
Ocrelizumab
EXPERIMENTALParticipants will receive ocrelizumab, as IV infusion Q24W. The first dose is given as dual infusions of half the dose of ocrelizumab on Days 1 and 15, and subsequent doses are given as single infusions of ocrelizumab Q24W. Participants will also receive a placebo of fingolimod administered as QD capsule.
Fingolimod
ACTIVE COMPARATORParticipants will receive fingolimod PO, QD as per the prescribing information provided with fingolimod. Participants will also receive a placebo of ocrelizumab administered as IV infusion on Days 1 and 15, and Q24W thereafter.
Interventions
Ocrelizumab, 300 milligrams (mg) will be administered as IV infusion to participants who weigh \< 35 kilograms (kg), and ocrelizumab 600 mg, IV will be administered to participants who weigh ≥ 35 kg on Days 1 and 15 (half the dose, 2 weeks apart), and Q24W thereafter.
Ocrelizumab matching placebo will be administered as IV infusion on Day 1 and Day 15, and Q24W thereafter.
Fingolimod will be administered QD as a capsule per the prescribing information (0.25 mg to participants who weigh ≤ 40 kg and 0.5 mg to participants who weigh \> 40 kg).
Eligibility Criteria
You may qualify if:
- Body weight ≥ 25 kg
- Diagnosis of RRMS in accordance with the International Pediatric Multiple Sclerosis Study Group (IPMSSG) criteria for pediatric multiple sclerosis (MS), Version 2012, or McDonald criteria 2017
- Expanded Disability Status Scale (EDSS) at screening: 0-5.5, inclusive
- For all countries except Germany, at least one MS relapse during the previous year or two MS relapses in the previous 2 years or evidence of at least one Gd-enhancing lesion on MRI within 6 months prior to randomization
- Participants in Group A (ocrelizumab in the DBP) and Group B (fingolimod in the DBP) who, in the opinion of the investigator, may benefit from switching to ocrelizumab and who have completed the DBP with study treatment (ocrelizumab/fingolimod), may participate in the OLE period
You may not qualify if:
- Known presence or suspicion of other neurologic disorders that may mimic MS
- Significant uncontrolled somatic diseases, known active infection or any other significant condition that may preclude participant from participating in the study
- Participants with severe cardiac disease or significant findings on the screening electrocardiograph (ECG)
- Participants who have discontinued the study during the DBP
