Brief summary

Efficacy and safety of ofatumumab and siponimod compared to fingolimod in pediatric patients with multiple sclerosis

Detailed description

The study is divided into a Core Part and Extension Part. The Core Part is a 24-month, double-blind, triple dummy, randomized, 3-arm active-controlled in children/adolescent patients aged 10-17 years old with Multiple Sclerosis (MS). The Extension Part is 60-month (5 year) open label (except for first 12 weeks transition which will remain double-blind) treatment for patients who complete the Core Part of the study and meet all inclusion/exclusion criteria. The targeted enrollment is 120 participants with multiple sclerosis which will include at least 5 participants with body weight (BW) ≤40 kg and at least 5 participants with age 10 to 12 years in each of the ofatumumab and siponimod arms. There is a minimum 6 month follow up period for all participants (core and extension). Total duration of the study could be up to 7 years.

Interventions

DRUGFingolimod

Fingolimod capsule administered orally once daily at a dose of either 0.5 mg or 0.25 mg (depending on patient's body weight).

DRUGOfatumumab

Ofatumumab as a solution for injection in an autoinjector containing 20 mg ofatumumab (50 mg/mL, 0.4 mL content) for subcutaneous administration. A loading dose at Day1, Day 7 and Day 14 and then injections every 4 weeks/ 6 weeks (depending on patient's body weight).

Siponimod tablet administered orally once daily. Titration period, Day 1 to Day 6, first dose is either 0.1 mg or 0.25 mg up to daily dose of either 0.5 mg, 1 mg or 2 mg (depending on CYP2C9 genotype and body weight).

Design outcomes

Primary

MeasureTime frameDescription
Annualized relapse rate (ARR) in target pediatric participantsBaseline up to 24 monthsFrequency of relapses assessed by the annualized relapse rate (ARR). The ARR is defined as the average number of confirmed relapses per year (total number of confirmed relapses divided by the total days in the study multiplied by 365.25).

Secondary

MeasureTime frameDescription
Annualized relapse rate (ARR) as compared to historical interferon β-1a dataBaseline up to 24 monthsFrequency of relapses assessed by the annualized relapse rate (ARR) to historical interferon β-1a data. The ARR is defined as the average number of confirmed relapses per year. The historical data for interferon β-1a will derived from prior phase 3 studies.
Annualized T2 lesion rateBaseline up to 24 monthsNumber of new/newly enlarged T2 lesions per year
Neurofilament light chain (NfL) concentrationsDay 1, Months 3,6,12,18,24Neurofilament light chain (NfL) concentration in serum of ofatumumab and/or siponimod versus fingolimod
Plasma Concentrations of ofatumumabDay 1, pre-dose for Day 7, Months 2,3,5,6,12,18,24Ofatumumab plasma concentrations
Plasma Concentrations of siponimodDay 1 (2,3,4,6 h), Day 3 (2,3,4,6 h), pre-dose for Months 1 (pre, 3h), 3,5,12Siponimod plasma concentrations
Plasma Concentrations of siponimod metabolite (M17)Pre-dose Month 3, 5 and Month 12Siponimod metabolite (M17) plasma concentration
Percentage of participants with anti-ofatumumab antibodiesDay 1, Pre-Dose Months 2,3,5,6,12,18,24Anti-ofatumumab antibodies to demonstrate immunogenicity of ofatumumab
Number of adverse events and serious adverse eventsBaseline up approximately 66 monthsAny clinically relevant finding that meets the criteria of an adverse event (as determined by the investigator) identified during the safety assessments (ECG, laboratory and ophthalmological data, pulmonary function tests and vital signs) will be reported as an adverse event
