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.

Detailed description

This Phase III randomized, double-blind, double-dummy, multicenter study will evaluate the safety and efficacy of ocrelizumab administered as intravenous (IV) infusion every 24 weeks (Q24W) compared with fingolimod taken orally (PO), once daily (QD), in children and adolescents with RRMS aged between 10 and \< 18 years. Participants will be randomized in a 1:1 ratio (ocrelizumab:fingolimod), globally. This study consists of a double-blind, double dummy period in which participants will be treated with either active ocrelizumab or active fingolimod for a flexible duration. Participants who complete the double-blind period will be offered the possibility to enter an optional open-label extension (OLE) treatment period of at least 144 weeks with ocrelizumab.

Interventions

DRUGOcrelizumab

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.

OTHEROcrelizumab Placebo

Ocrelizumab matching placebo will be administered as IV infusion on Day 1 and Day 15, and Q24W thereafter.

DRUGFingolimod

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).

Fingolimod matching placebo will be administered QD as a capsule.

Inclusion criteria

* 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 Inclusion Criteria for Optional OLE Period: -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

Exclusion criteria

* 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)

Design outcomes

Primary

MeasureTime frameDescription
Protocol-defined Annualized Relapse Rate (ARR)Up to after the last participant randomized completed 24 weeks since first study treatment administration (up to approximately 160 weeks)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.

Number of New or Enlarging T2-hyperintense Lesions (T2 Lesions), as Detected by Brain Magnetic Resonance Imaging (MRI)Up to after the last participant randomized completed 24 weeks since first study treatment administration (up to approximately 160 weeks)Number of new or enlarging T2 lesions for each participant was calculated as the sum of the individual number of new or enlarging T2 lesions as detected by brain MRI.
Number of T1 Gd Lesions at Week 12At Week 12Brain MRI with and without a Gd-contrast agent were performed to assess the number of Gd lesions.
Number of Participants With Adverse Events (AEs)Up to approximately 7 yearsAn AE was defined as any untoward medical occurrence in a clinical investigation subject administered a pharmaceutical product, regardless of causal attribution. An AE can therefore be any unfavorable and unintended sign, symptom, or disease temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product.
Maximum Serum Concentration (Cmax) of OcrelizumabCycle (1 Cycle=24 weeks)
Area Under the Plasma Concentration-time Curve Over a Dosing Interval (AUC Tau) of OcrelizumabCycle 1 (1 Cycle=24 weeks)
Number of Participants With Anti-drug Antibodies (ADAs) to OcrelizumabUp to approximately 7 yearsParticipants were considered to be ADA positive if they were ADA negative or had missing data at baseline but developed an ADA response following study drug exposure (treatment-induced ADA response), or if they were ADA positive at baseline and the titer of one or more post-baseline samples was at least 0.60 titer unit greater than the titer of the baseline sample (treatment-enhanced ADA response). The total number of participants who developed ADAs to atezolizumab was determined by summing the ADA-positive participants across all timepoints.
Levels of Cluster of Differentiation 19 (CD19) + B-cell Count in BloodUp to approximately 7 yearsCD19+ B-cell count in blood will be assessed using flow cytometry.
