A Randomized, Open Label, Multi-center, Active-comparator Study to Assess Efficacy, Safety & Tolerability of Ofatumumab 20mg sc Monthly Versus Continued Current Therapy in Relapsing-remitting Multiple Sclerosis After Elevation of Serum Neurofilament Light Levels (SOSTOS)
ClinicalTrials.gov Identifier:
Novartis Reference Number:COMB157GUS09
All compounds are either investigational or being studied for (a) new use(s). Efficacy and safety have not been established. There is no guarantee that they will become commercially available for the use(s) under investigation.

Study Description

This study will evaluate if relapsing-remitting MS patients that have not had a relapse in the past year would benefit from a switch to ofatumumab versus staying on their continued current therapy. This study will also look at whether an elevated serum neurofilament light (NfL) level predicts enhanced benefit from a switch to ofatumumab. This is a multicenter, prospective study of up to 150 relapsing-remitting MS participants/ The study is looking to see if patients who have not had a relapse in the past year would benefit from switching to ofatumumab.

After giving consent, participants will have a 1 week screening/qualification period. If they qualify to continue, they will start a a six month run-in period during which lab samples will be collected. Patients that are relapse-free during the run-in period will continue into next period of the study in which they will be randomized to either ofatumumab or continued therapy for the next 15 months. Every 3 out of 5 randomized participants will be selected to wear a digital study watch to collect physical activity, sleep, and vitals during this 15 month period. The study watch will be worn 24 hours a day, 7 days a week but can be removed during showers/bathing. At the end of the 15 month period, a study completion visit will be held.

The total study duration is 21 months plus 1 week for screening/qualification.
