- Introduction: Dimethyl fumarate (DMF) is an oral therapy for relapsing-remitting multiple sclerosis (RRMS). DMF is included in the Swedish post-market surveillance study “Immunomodulation and Multiple Sclerosis Epidemiology” (IMSE).Objectives/Aims: To assess the effectiveness and safety of DMF with focus on patients treated at least 72 months.Methods: Descriptive data of Extended Disability Status Scale (EDSS), Multiple Sclerosis Severity Scale (MSSS), Symbol Digit Modalities Test (SDMT), Multiple Sclerosis Impact Scale (MSIS-29), European Quality of Life - 5 Dimensions Test (EQ-5D), Visual Analog Scale (VAS), Adverse Events (AEs) and Serious AEs (SAEs) is obtained from the nationwide Swedish Neuro Registry (NeuroReg). Effectiveness measures were assessed using the Wilcoxon Signed Rank Test and drug survival using the Kaplan-Meier curve.Results: 2565 DMF-treated patients were included between March 2014 and March 2022 with an overall drug survival rate of 38.7% and a mean treatment duration of 37 months. The main reasons for discontinuation were AEs (47%) and lack of effect (30%). 199 AEs were reported of which 63 were serious. For both serious and non-serious AEs reported, gastrointestinal disorders were the most common (19% and 27%, respectively).509 patients had continuous treatment for at least 72 months. This cohort had a mean age of 42 years and a mean treatment duration of 84 months. The majority (51%) had switched from interferon or glatiramer acetate and 24% were treatment naïve.Significant improvements in mean values at 72 months of treatment compared to baseline were noted for MSSS, MSIS-29 Psychological, and EQ-5D (p<0.05). All other tests remained stable after 6 years of treatment. Number of relapses per 1000 patient years were improved from 199.6 before DMF treatment start to 23.0 during treatment with DMF.49 patients (10%) have discontinued DMF treatment in the 72 month cohort with a mean treatment duration of 84 months (range 70-97 months). The main reasons for discontinuation were other reasons (33%), lack of effect (29%), stable condition (14%), and AEs (12%).Conclusions: DMF demonstrates partly clinical improvements in patients treated 72 months. However; due to the high discontinuation rate there is an unavoidable selection bias. Continued follow up is needed to assess the effectiveness and safety of DMF over longer time periods in a real world setting.
