Clinical Trial Summary

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.

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Proportion of patients demonstrating NEDA-3	Proportion of patients demonstrating No Evidence of Disease Activity (NEDA)-3 (12-24 months) in both cohorts, respectively. NEDA-3 is defined by no confirmed Multiple Sclerosis relapse, no new or enlarging T2 lesions, no Gadolinium-positive T1 lesions, and no six-month confirmed disability worsening.	from month 12 up to month 24
Secondary	Proportion of patients demonstrating no evidence of disease activity in individual components of NEDA-3	Proportion of patients demonstrating no evidence of disease activity in individual components of NEDA-3 (12-24 months) in the overall population and in both cohorts.	12-24 months
Secondary	Multiple Sclerosis Impact Scale Questionnaire (MSIS-29)	Treatment effect of Ofatumumab on the impact of multiple sclerosis as measured by MSIS-29 (baseline, 12 and 24 months) in the overall population and in both cohorts.; MSIS-29 is a 29-item self-report measure with 20 items associated with a physical scale and 9 items with a psychological scale. Items ask about the impact of MS on day-to-day life in the past two weeks. All items have 4 response options. Each score domain is obtained by summing all individual items and transformed it to a -100 scale where high scores indicate worse health.	Baseline, Month 12, Month 24
Secondary	Fatigue Symptoms and Impacts Questionnaire - Relapsing Multiple Sclerosis (FSIQ-RMS)	Treatment effect of Ofatumumab on the impact of multiple sclerosis as measured by FSIQ-RMS (baseline, 12 and 24 months) in the overall population and in both cohorts.; The FSIQ-RMS is a patient-reported outcome (PRO) instrument used to assess fatigue in patients with relapsing types of multiple sclerosis (RMS).It is a 20-item self-report measure with 7 items for MS-related symptoms of fatigue and 13 for fatigue-related impacts on several aspects of patients' lives. The impact of fatigue divides into 3 subdomains: physical, cognitive and emotional, and coping. The scores for fatigue and the subdomains of impact are standardized to a 0-100 scale using a scoring algorithm, with higher scores indicating more severe symptoms and impacts.	Baseline, Month 12, Month 24
Secondary	Treatment Satisfaction Questionnaire for Multiple Sclerosis (TSQM-9)	Treatment satisfaction with Ofatumumab as measured by TSQM-9 (baseline, 12 and 24 months) in the overall population and in both cohorts.; The TSQM-9 is a validated tool, widely used, to measure treatment satisfaction that will be applied in the context of this study regarding Ofatumumab. The TSQM-9 uses nine of the 14 TSQM Version 1.4 items, not including five questions related to side effects of medication, and comprises three scales: the effectiveness scale, the convenience scale and the global scale. The TSQM-9 domain scores range from 0 to 100 with higher scores representing higher satisfaction on that domain.	Baseline, Month 12, Month 24
Secondary	Proportion of patients permanently discontinuing Ofatumumab during the study	Proportion of patients permanently discontinuing Ofatumumab during the study, and reasons for discontinuation in the overall population and in both cohorts	up to month 24
Secondary	Proportion of patients demonstrating NEDA-3 in the overall population.	Proportion of patients demonstrating NEDA-3 in the overall population.	12-24 months
