- 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.

- Background: 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).Objective: To assess the effectiveness and safety of DMF with focus on patients treated at least 36 months in the IMSE study.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) and Adverse Events (AEs) 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: 2229 DMF-treated patients were included since March 2014 with a one- and two-year drug survival rate of 73% and 59%. The main reasons for discontinuation were AEs (51%) and lack of effect (29%). 77 AEs were reported to the Swedish Medical Products Agency of which 20 were serious. There were 6 fatal cases of which 4 were confirmed as unrelated to DMF and 2 were still under investigation.865 patients had continuous treatment for at least 36 months. This cohort had a mean age of 42 years and a mean treatment duration of 44 months. The majority had switched from interferon and glatiramer acetate (IFN&GA) (50%) or were treatment naïve (TN) (22%). Significant improvements in mean values at 36 months of treatment compared to baseline were noted for EDSS, MSSS, SDMT, MSIS-29 Psychological and EQ-5D. When TN patients were solely assessed improvements were noted for EDSS, MSSS, SDMT, MSIS-29 Physical and Psychological and EQ-5D. Treatment experienced patients displayed significant improvements only for MSSS and EQ-5D. Patients previously treated with IFN&GA also improved only in MSSS and EQ-5D. TN patients had a mean duration from diagnosis to treatment start of 6 months compared to 83 months for IFN&GA patients and 105 months for the remaining cohort.Conclusions: DMF demonstrates clinical improvements in patients treated ⩾ 36 months, most pronounced in TN patients. However; the tolerability of DMF was reduced since 41% interrupted treatment during the first 24 months of therapy. Continued follow up is needed to assess the effectiveness and safety of DMF over longer time periods in a real world setting.

- Introduction: Natalizumab (NTZ) is a highly effective disease modulatory treatment for relapsing-remitting multiple sclerosis (RRMS). Post-marketing surveillance is important for evaluation of long-term safety and effectiveness in a real-world setting. To this end the “Immunomodulation and Multiple Sclerosis Epidemiology Study” (IMSE 1) was initiated upon NTZ launch in Sweden (Aug 2006).Objectives/Aims: To follow-up the long-term effectiveness and safety of NTZ in a real-world setting.Methods: Adverse events (AEs), Serious AEs (SAEs), John Cunningham virus status (JCV) and clinical effectiveness measures; Extended Disability Status Scale (EDSS), Multiple Sclerosis Severity Scale (MSSS), Symbol Digit Modalities Test (SDMT) and Multiple Sclerosis Impact Scale (MSIS-29) data is collected from the nationwide Swedish Neuro Registry (NeuroReg). Effectiveness measures were assessed using the Wilcoxon Signed Rank Test.Results: A total of 3622 NTZ patients were included in the IMSE 1 study from August 2006 until March 2022 (72% female; mean age 36 years; 80% RRMS; mean treatment duration 49 months) and 186 had been treated for at east 132 months. Of the 132-month cohort, 73% were female, the mean age was 36 years, 88% had RRMS, and the mean treatment duration was 155 months. The majority were treated with interferons and glatiramer acetate prior NTZ (64%). 25% (47/186) discontinued NTZ treatment of which 47% (n=22) discontinued due to JCV positive (JCV+). In total, 30% (55/186) of these patients were JCV+ with a mean JCV index of 1.2±1.0 (2% missing data). Relapses before treatment were reduced from 380/1000 patient years to 43/1000 during treatment, 71% were relapse-free and 18% had 1 relapse during the entire treatment period (15% missing data). Most clinical effectiveness measures, MSSS, MSIS-29 and SDMT showed statistically significant improvement between baseline and 132 months (p<0.05). Over the entire observation time, 125 SAEs had been reported to the Swedish MPA including 9 cases (2 fatal) of progressive multifocal leukoencephalopathy (PML) of which 8 occurred between 2008 and 2012, and one in 2018.Conclusions: NTZ is generally well tolerated with sustained effectiveness regarding cognitive, physical and psychological measures, as well as relapse-control. Introduction of JCV testing has led to fewer treated JCV+ patients, which likely explains a drastic drop in number of reported cases of PML.

- 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.

- Background: Alemtuzumab (ALZ) is an approved disease-modifying therapy (DMT) for 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” (IMSE) upon launch in Sweden (March 2014).Objective: To track 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 all 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).Results: A total of 118 MS patients (59% female; 95% RRMS) were included in IMSE 3 between March 2014 and April 2019. 95 patients had started ALZ >24 months ago (63% female; 98% RRMS) at cut-off date (31st of Mars 2019), where only 3 patients had switched to another DMT. Mean age at treatment start for patients treated at least 24 months was 34 years and mean treatment duration was 42 months. Mean number of drugs prior ALZ initiation was 2.3. Most patients (41/95) switched to ALZ from natalizumab, while 14/95 patients were treatment naïve with ALZ. The number of relapses per 1,000 patient years decreased from 471 before ALZ initiation to 65 during ALZ treatment (n=83, missing data; n=12). In patients treated ⩾ 24 months significant improvements in mean were seen for EDSS (1.9 ± 1.4 to 1.6 ± 1.3, n=57), MSSS (3.3 ± 2.6 to 2.4 ± 2.1, n=48) and EQ-5D (0.7 ± 0.3 to 0.8 ± 0.3, n=53), while MSIS-29, SDMT and VAS scores remained stable. A total of 28 adverse events were reported to the Swedish Medical Products Agency, 12 events were classified as serious and 16 events as non-serious. Two patients died during ALZ treatment, of which one patient died in association with the first ALZ treatment cycle due to fulminant viral hepatitis.Conclusions: Patients treated with ALZ for at least 24 months improved or remained stable across all effectiveness measures. Only a very small percentage of patients switched to other DMTs. Continued follow-up is needed to address long term effectiveness and safety of ALZ.
