Efficacy and Safety of Ofatumumab Compared to Teriflunomide in Patients With Relapsing Multiple Sclerosis

This was a randomized, double-blind, double-dummy, active comparator-controlled, parallel-group, multi-center study with variable treatment duration in approximately 900 patients with relapsing multiple sclorosis (RMS). The maximal treatment duration in the study for an individual patient was 2.5 years.

Eligible patients were randomized to receive either experimental ofatumumab subcutaneous (s.c.) injections every 4 weeks or active comparator teriflunomide orally once daily. The dose regimen for ofatumumab for this study was a loading dose regimen of 20 mg at Day 1, Day 7 and Day 14, followed by a maintenance dose regimen of 20 mg administered every 4 weeks starting at Week 4. In order to blind for the different formulations, double-dummy masking was used i.e. all patients will take injections (containing either active ofatumumab or placebo) and oral capsules (containing either active teriflunomide or placebo).
