Study Description
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. 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.
