About

This non-interventional study will compare the effect of Ofatumumab treatment between patients that began Ofatumumab within the 3 years after Multiple Sclerosis diagnosis and patients that began Ofatumumab with more than 3 years of Multiple Sclerosis diagnosis in a real-world setting in Portugal.

Full description

This is a 2 cohort, multi-center, observational study carried out in Portugal that aims to describe the effectiveness of Ofatumumab in a setting of routine medical care. Primary data will be collected from Multiple Sclerosis patients who initiate Ofatumumab early and later in their disease (cohorts 1 and 2, respectively).

Data will be collected during 3 visits distributed over a maximum period of 24 months. Exceptionally, if the patient shows Expanded Disability Status Scale (EDSS) worsening in visit 2 or 3 (12 and 24 months after Ofatumumab initiation, respectively), there will be an additional visit 6±1 months after visit 2 or 3 for EDSS confirmation.

The study includes patients that have initiated Ofatumumab up to 12 months prior inclusion in the study OR Patients that are initiating Ofatumumab at the moment of study inclusion.

Patients in both cohorts will have to be treated with Ofatumumab for at least two years to compare No Evidence of Disease Activity (NEDA)-3 at 12 to 24 months, respectively.
