- Background: Dimethyl fumarate (DMF) is an oral therapy for relapsing-remitting multiple sclerosis (RRMS), which has been included in the Swedish post-market surveillance study “Immunomodulation and Multiple Sclerosis Epidemiology 5” (IMSE 5) in order to monitor and determine the long-term safety and effectiveness in a real-world setting.Objectives: To follow-up the long-term safety and effectiveness of DMF in a real-world setting.Methods: MS patients are registered into the nationwide Swedish Neuro Registry (NeuroReg) in Sweden. The IMSE 5 study obtains descriptive data of adverse events (AEs), 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 - Five Dimensions Test (EQ-5D) and Visual Analog Scale (VAS) from NeuroReg. Drug survival was measured using the Kaplan-Meier curve and effectiveness measures were assessed using the Wilcoxon Signed Rank Test.Results: 2010 DMF-treated patients have been included in the IMSE 5 study between March 2014 and April 2018. 73 % were female and the mean age at treatment start was 40.6 years. The mean treatment duration was 22.3 months. 92 % of the patients had RRMS with 2 % missing data on MS phenotype. Most patients switched from interferon and glaimer acetat (41 %) and 24 % of the patients were treatment naïve (13 % were missing data on prior treatment). The overall one year drug survival was 74 % and 889 patients terminated their treatment at some point. Most patients (39 %) switched to rituximab (15 % have no new treatment registered). The most common reason for discontinuation was AEs (53 %) and lack of effect (29 %). 227 (11 %) patients have continued treatment for ≥36 months. In patients treated with DMF continuously for ≥24 months (n=918), significant improvements in mean values at 24 months of treatment compared to mean baseline values have been noted for EDSS (1.9 ± 1.6 to 1.6 ± 1.6, n=196); MSSS (2.5 ± 2.4 to 2.0 ± 2.0, n=145); SDMT (52.6 ± 11.0 to 53.8 ± 11.7, n=315); MSIS-29 Psychological Subscale (26.3 ± 22.8 to 21.8 ± 20.6, n=337); and EQ-5D (0.76 ± 0.23 to 0.81 ± 0.20, n=284).Conclusions: NeuroReg proves to function well as a post-marketing drug surveillance platform, providing data regarding drug effectiveness and AEs. A longer follow-up period is needed to assess the real-world effectiveness and safety of DMF.

- Background: Teriflunomid (TFM) is an oral therapy for relapsing-remitting multiple sclerosis (RRMS), which has been included in the Swedish post-market surveillance study “Immunomodulation and Multiple Sclerosis Epidemiology 4” (IMSE 4) in order to surveille and determine the long-term safety and effectiveness in a real-world setting.Objectives: To follow-up the long-term safety and effectiveness of TFM in a real-world setting.Methods: MS patients are registered into the nationwide Swedish Neuro Registry (NeuroReg) in Sweden. The IMSE 4 study obtains descriptive data of adverse events (AEs), 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 - Five Dimensions Test (EQ-5D) and Visual Analog Scale (VAS) from NeuroReg. Drug survival was measured using the Kaplan-Meier curve.Results: 481 TFM-treated patients have been included in the IMSE 4 study between March 2014 and April 2018. 70 % were female and the mean age at treatment start was 45.8 years. The mean treatment duration was 20.5 months. 89 % of the patients had RRMS with 3 % missing data on MS phenotype. Most patients switched from interferon and glatimer acetat (37 %) and 14 % of the patients were treatment naïve before starting TFM. The overall one year drug survival rate was 81 % and the overall two year drug survival rate was 41 %. 168 (35 %) patients terminated their treatment at some point, of which 33 % started rituximab treatment and 22 % have no new treatment registered. The most common reasons for discontinuation were AEs (49 %) and lack of effect (40 %). 318 patients have been continuously treated with TFM for ≥12 months and mean baseline values compared to val-ues at 12 months have been noted for EDSS (2.0 ± 1.5 to 2.2 ± 1.5, n=141); MSSS (2.6 ± 2.2 to 2.9 ± 2.3, n=126); SDMT (50.8 ± 10.5 to 50.8 ± 10.7, n=165); MSIS-29 Physiological subscale (20.2 ± 19.3 to 19.7 ± 20.0, n=181); MSIS-29 Psychological subscale (28.1 ± 22.2 to 23.7 ± 21.7, n=181); EQ-5D (0.74 ± 0.24 to 0.73 ± 0.26, n=154); and VAS (70.0 ± 20.8 to 70.8 ± 19.6, n=150).Conclusions: NeuroReg proves to function well as a post-marketing drug surveillance platform, providing data regarding drug effectiveness and AEs. However, a longer follow-up period is needed to assess the real-world effectiveness and safety of TMF.

- Background: Alemtuzumab (ALZ) is a modulatory drug for patients with relapsing-remitting multiple sclerosis (RRMS). Post-marketing surveillance is important to assess the long-term safety and effectiveness in a real-world setting where ALZ was included into the Swedish post-market surveillance study “Immunomodulation and Multiple Sclerosis Epidemiology Study 3” (IMSE 3) upon launch in Sweden (March 2014).Objective: To follow up the effectiveness and long-term safety of ALZ in a real-world setting.Methods: Swedish MS patients are registered in the nationwide Swedish Neuro Registry (NeuroReg).IMSE 3 includes patients starting ALZ treatment with annual clinical measures obtained from NeuroReg; 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 Dimension Test (EQ-5D) and Visual Analogue Scale (VAS). The Wilcoxon signed-rank test was used to assess changes in effectiveness.Results: 118 patients (59% female; 95% RRMS) have been included in IMSE 3 between March 2014 and April 2021. Mean age at treatment start was 34 years. At cut-off date 85 patients had been treated with ALZ with at least 48 months of follow-up. Mean values at baseline compared to 48 months showed significant improvements for MSSS and SDMT while EQ-5D, EDSS, MSIS-29 and VAS scores showed tendencies of improvement.The largest proportion of the entire cohort switched from natalizumab (39%) or were treatment naïve (14%) prior ALZ. The number of relapses per 1,000 patient years decreased from 441 before ALZ initiation to 84 during ALZ treatment (16% missing data). 36 adverse events (AEs) were reported to the Swedish Medical Products Agency. 23 were classified as serious and the most common AEs categories were infections and infestations and blood and lymphatic system disorders (23% respectively). For non-serious events endocrine disorders (43%) was the most common category. Two patients died during ALZ treatment, one of which was associated to ALZ treatment, and died in association with the first ALZ treatment cycle due to fulminant viral hepatitis.Conclusions: Patients treated with ALZ for at least 48 months improved or remained stable across all effectiveness measures. Continued follow-up is needed to evaluate the real-world effectiveness and safety of ALZ.
