Relapsing-remitting Multiple Sclerosis Clinical Trial

Official title: COMparison Between All immunoTherapies for Multiple Sclerosis. An Observational Long-term Prospective Cohort Study of Safety, Efficacy and Patient's Satisfaction of MS Disease Modulatory Treatments in Relapsing-remitting Multiple Sclerosis

Status Active, not recruiting

Clinical Trial Summary

The overarching goal of this study is to determine whether rituximab (RTX) offers effectiveness and safety advantages over other commonly used approved Disease-Modifying Drugs (DMT) in the largest real-world population-based structured prospective follow-up cohort of Relapsing-Remitting Multiple Sclerosis (RRMS) patients. The study will include both treatment naïve patients starting their first DMT and patients switching from a previous first line DMT (escalation/second-line).

Clinical Trial Description

This is a prospective non-intervention observational prospective cohort study assessing the long-term safety and efficacy of RTX treatment in MS compared with other common MS DMTs regarding both clinical and radiological parameters in a real-life population of patients with MS.

A number of parameters will be assessed annually. These include baseline demographics, previous drug history and reasons for discontinuation, disability status (expanded disability status scale), relapses, safety and adverse events (AE), contrast enhancing T1 and newly appearing T2 lesions on magnetic resonance imaging, as well as a panel of patient reported outcome measures: Symbol Digit Modalities Test (SDMT); MS impact scale-29 (MSIS-29) Fatigue Scale for Motor and Cognitive Functions (FSMC), EuroQol-5 Dimensions (EQ-5D), the MS check scale and Treatment Satisfaction Questionnaire 9 (TSQM-9).

Retrospective data entered in medical charts and the Swedish MS registry will be included together with prospective annual structured follow up from inclusion into the study for a minimum of three years (three to nine years).

In a substudy - Covid Enhancement study - analyses will be performed regarding the effect of COVID-19 on people with MS as compared to non-MS individuals and also if there is any indication that a particular DMD is associated with a risk to contract a more severe COVID-19. The analyses will primarily be performed in official health care databases. ;
