- 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.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- 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. ALZ has therefore been 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 into the nationwide Swedish Neuro Registry (NeuroReg). IMSE 3 includes patients starting ALZ treatment. Adverse events (AEs) and clinical meas-ures; 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) are obtained from NeuroReg. The Wilcoxon signed-rank test was used to assess changes in effectiveness.Results: 110 patients (60% female; 95% RRMS) have been included in IMSE 3 between March 2014 and April 2018. Mean age at treatment start was 34 years and mean treatment duration was 28 months. Most patients (40%) switched from natalizumab and 14% were treatment naïve. 103 patients were currently treated with ALZ at cut-off date and 97 patients had been treated for at least 12 months. Seven patients had discontinued ALZ treatment, of which five patients switched to another disease modifying therapy, one patient died in association with the first ALZ treatment cycle due to fulminant viral hepatitis and one patient had no treatment registered after ALZ discontinuation. In total, 20 AEs were reported to the Swedish Medical Products Agency; 13 events were classified as non-serious. In patients treated at least 12 months significant improvements were seen for EDSS (2.0±1.4 to 1.6±1.3, n=67), MSSS (3.4±2.6 to 2.6±2.3, n=58), MSIS-29 Physical (22.9±21.0 to 17.5±18.0, n=83), VAS (66.9±22.0 to 73.7±18.5, n=68) and EQ-5D (0.7±0.3 to 0.8±0.3, n=74). MSIS-29 Psychological and SDMT did not improve significantly.Conclusions: NeuroReg functions well as a post-marketing drug surveillance platform, providing data regarding drug effectiveness and AEs. A longer follow-up period is needed to evaluate the real-world effectiveness and safety of ALZ.

- Background: Fingolimod (FGL) is an oral therapy for patients with relapsing-remitting multiple sclerosis (RRMS) and the efficacy has been shown in phase II and III studies. However; long-term surveillance and safety is important, therefore FGL is included in the Swedish “Immunomodulation and Multiple Sclerosis Epidemiology Study 2” (IMSE 2).Objective: To follow up the effectiveness and long-term safety of FGL in a real-world setting.Methods: Swedish MS patients are registered into the nationwide Swedish Neuro Registry (NeuroReg). IMSE 2 includes data of adverse events (AEs) and clinical measures; 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), obtained from NeuroReg.Results: From September 2011 until April 2018, 1617 patients (67% female; 91% RRMS) were included in IMSE 2. At treatment start 38 patients were ≤20 years (yr), 308 aged 21-30 yr and 1271 aged >30 yr. Mean treatment duration was 34 months. 852 patients were currently treated with FGL at cut-off date and 1230 patients had been treated for at least 12 months. In total, 39% switched treatment from interferons or glatiramer acetate, 26% from natalizumab and 5% from dimethyl fumarate or teriflunomide. 803 patients have discontinued FGL at some point, mainly due to lack of effect (43%) or AEs (34%), most patients switched to rituximab after FGL discontinuation. Relapses were reduced from 281 to 87/1000 patient years (PY) when comparing before and during FGL treatment. In patients aged ≤20 yr, 21-30 yr and >30 yr relapses were reduced from 694 to 144/1000 PY, 455 to 129/1000 PY and 258 to 77/1000 PY, respectively. After 12 months significant improvements were seen in EQ-5D (0.7 to 0.8, n=752), MSSS (3.1 to 2.9, n=410), MSIS-29 Physical (21.1 to 20.0 n=812), MSIS-29 Psychological (29.2 to 24.9, n=812), SDMT (54.3 to 57.0, n=751) and VAS (70.9 to 72.8, n=692). When analysing age groups separately significant improvements were seen in MSSS, SDMT, and MSIS-29 Psychological in patients aged 21-30 yr and >30 yr. EQ-5D, VAS and MSIS-29 Physical significantly improved in patients aged >30 yr.Conclusions: FGL is a generally well-tolerated drug that reduces the clinical activity in MS patients. NeuroReg functions well as a drug surveillance platform, enabling monitoring of long-term effectiveness and AEs.
