Details and patient eligibility


This study will evaluate the impact of ofatumumab in Relapsing Remitting Multiple Sclerosis (RRMS) participants that are very early in the course of their disease using clinical and magnetic resonance imaging (MRI) outcomes. The study will also assess changes in disease using monitoring techniques including digital biometric device use, biomarker analysis and non-conventional MRI. Select outcomes in the ofatumumab treated group will be compared to a group of Healthy participants to determine if there are similarities between the groups after the patients with MS undergo treatment with ofatumumab.

Full description

The study is an open-label, multi-center, prospective 18-month study in 118 MS participants with early RRMS (defined as within 6 months of diagnosis of clinically definite RRMS) and who are treatment naïve. It is designed to determine if RRMS participants treated with 20 mg subcutaneous monthly ofatumumab during the earliest part of their disease will benefit from the use of ofatumumab as their first disease modifying therapy. Additionally, RRMS patients will be compared to age- and sex-matched healthy participants (n=50) for select outcomes to observe similarities and differences between the groups. After giving consent, participants will have a 28-day screening/qualification period. If they qualify to continue, they will start study measures including assessments of clinical and magnetic resonance imaging (MRI) metrics and use of a digital monitoring watch. Additionally, samples will be collected for laboratory and biomarker analysis. RRMS participants will begin treatment with ofatumumab for the next 18 months. Healthy participants will undergo similar assessments; however they will not receive any treatment during the course of the study. Over the 18 months, participants will have regular clinical visits with assessments and sample collection. After 18 months in the trial, participants in both groups will have the option to enter into a 12-month extension (up to 30 months total in study) to collect further information on long-term clinical and MRI outcomes.

Primary purpose




Interventional model

Single Group Assignment


None (Open label)

182 participants in 2 patient groups

Experimental group
Ofatumumab will be provided in an autoinjector for subcutaneous administration. Dosing regimen for this study is an initial dose of 20mg at Baseline/Week 0, followed by Week 1, 2 and every month thereafter, beginning at Week 4 (Month 1) until Month 18. There will be an optional extension of dosing through month 30.
Drug: Ofatumumab
Healthy Control
No Intervention group
Healthy Control arm will be age- and sex-matched subjects (to the ofatumumab treated arm) and will not receive a study treatment.
