- 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).Objectives: 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: 2349 DMF-treated patients were included between March 2014 and June 2020 with an overall drug survival rate of 45%. The main reasons for discontinuation were AEs (50%) and lack of effect (30%). 186 AEs were reported to the Swedish Medical Products Agency, of which 59 were serious. A total of 8 patients have died during DMF treatment or within 6 months of treatment discontinuation. 36 month cohort: 940 patients had con-tinuous treatment for at least 36 months. This cohort had a mean age of 42 years and a mean treatment duration of 56 months. The majority (50%) had switched from interferon or glatiramer ace-tate, and (24%) were treatment naïve (TN). Significant improve-ments in mean values at 36 months of treatment compared to baseline for the 36-month cohort were noted for MSSS, SDMT, MSIS-29 Psychological, EQ-5D and VAS. When TN patients were solely assessed (n=230) improvements were noted for all above mentioned measures as well as MSIS-29 Psychological. The remaining patients in the cohort; treatment experienced patients (n=710) displayed significant improvements only for MSSS, MSIS-29 Psychological and EQ-5D. TN patients had a mean duration from diagnosis to treatment start of 5 months com-pared to 91 months for the remaining cohort. TN were also younger than the remaining cohort (37 years vs 43 years).Conclusions: DMF demonstrates clinical improvements in patients treated 36 months, more pronounced in TN patients. 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: Cladribine is a deoxyadenosine analogue prodrug. Cladribine tablets (CT) are administered in two courses, 12 months apart, for patients with relapsing multiple sclerosis (RMS). CT are included in the Swedish post-market surveillance study “Immunomodulation and Multiple Sclerosis Epidemiology” (IMSE).Objectives: To assess the safety and effectiveness of CT in a real-world setting with focus on patients treated at least 12 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), relapses and Adverse Events (AEs) is obtained from the nationwide Swedish Neuro Registry (NeuroReg). Effectiveness measures were assessed using the Wilcoxon Signed Rank Test and relapse rates were tested using the paired samples T-test.Results: 85 patients were included in the IMSE 10 study since CT were introduced on the Swedish market in April 2018. 42 patients were treated for at least 12 months. Five AEs were reported since the study start, four were classified as infections and infestations. 25 % of the entire cohort was treated with CT as their first MS drug. 13 % were treated with natalizumab and 12 % with dimethyl fumarate prior to CT. Five AEs were reported since the study start, four were classified as infections and infestations. Relapse data was available for 27/42 patients in the 12-month cohort. The number of reported relapses decreased significantly from 208.6 per 1,000 patient years before treatment start to 83.6 during treatment. Only three patients in this cohort experienced a relapse during treatment of which two were during the first treatment year. Significant improvements in mean values at 12 months of treatment compared to baseline were noted for MSSS for the 12-month cohort (n=17). All other tests remained stable but significantly unchanged after one year of treat-ment. Lymphocyte levels decreased from a mean of 2.4 x 109/L at treatment start (n=8) to 1.2 x 109/L after 12 months of treatment (n=6) in the 12-month cohort. No patients were below the 0.8 x 109/L limit at 12 months.Conclusions: CT treatment demonstrates clinical stability in patients treated 12 months. However, continued follow-up is needed to assess the effectiveness and safety of CT over a longer time to assess if these results sustain after the final treatment course has been administered.

- Background: Teriflunomid (TFM) is an oral therapy for relaps-ing-remitting multiple sclerosis (RRMS), which has been included in the Swedish post-market surveillance study “Immunomodulation and Multiple Sclerosis Epidemiology” (IMSE).Objectives: To assess the long-term safety and effectiveness of TFM for patients treated in a real-world setting over time.Methods: A large majority of MS patients are registered into the nationwide Swedish Neuro Registry (NeuroReg). 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. Effectiveness measures were assessed using the Wilcoxon Signed Rank Test and drug survival using the Kaplan-Meier curve.Results: 609 TFM-treated patients had been included in the IMSE 4 study from March 2014 to June 2020, 70% were female and mean age at treatment start was 46 years. Mean treatment duration was 27 months and 89% of the patients had RRMS. The most common prior treatment was interferon beta or glatiramer acetate (39%) and 17% of the patients were treatment naïve. The overall one- two- and three- year drug survival rates were 73%, 59% and 48% respectively. 307 (50%) patients had discontinued treatment at some point, of which 34% started rituximab treatment (36% had no new treatment registered). The most common rea-sons for discontinuation were AEs (42%) and lack of effect (40%). 204 patients had been continuously treated with TFM for ⩾36 months and significant changes in mean baseline values compared to values at 36 months were noted only for EDSS (2.0 ± 1.6 to 2.3 ± 1.8, n=49). All other clinical measures were stable. A total of 68 AEs were reported of which 20 events were classified as serious (S). The most common AE category was skin and subcutaneous tissue disorders for both serious and non-serious (NS) AEs (S: 25%, NS: 21%).Conclusions: NeuroReg proves to function well as a post-market-ing drug surveillance platform, providing data regarding drug effectiveness and AEs. Patients starting TMF are older at treat-ment start than patients initiating most other DMTs, which may explain the lack of significant improvement in most clinical meas-ures and the negative outcome of the EDSS scores. A longer fol-low-up period is needed to assess the real-world effectiveness and safety of TMF.

- Background: Natalizumab (NTZ) is a highly effective disease modulatory treatment for relapsing-remitting multiple sclerosis (RRMS). Post-marketing surveillance is important for evalua-tion 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 (August 2006).Objectives: To follow-up the long-term effectiveness and safety of NTZ in a real-world setting, with focus on patients treated at least 10 years.Methods: IMSE 1 includes patients starting NTZ treatment and data is collected from the nationwide Swedish Neuro Registry (NeuroReg). Adverse events (AEs), JC-virus status (JCV) and clinical effectiveness measures are registered in NeuroReg pro-spectively. Effectiveness measures were assessed using the Wilcoxon Signed Rank Test.Results: A total of 3291 patients were included in the IMSE 1 study from August 2006 until June 2020 (72% female; mean age 36 years; 80% RRMS; mean treatment duration 50 months). 171/3291 patients (5%) had been treated for at least 120 months (73% female; men age 36 years; 87% RRMS; mean treatment duration 139 months). A total of 64% (110/171) were treated with interferons or glatiramer acetate prior to NTZ treatment. Over the duration of follow-up discontinued 21% (35/171) their NTZ treat-ment of which 46% (16/35) discontinued due to JCV positive (JCV+). In total, 27% (46/171) of these patients were JCV+ with a mean JCV index of 1.2±1.0 (4% missing data). The mean num-ber of relapses were reduced from 0.84 one year before NTZ treat-ment start to 0.00 during the first treatment year (12% missing data). All clinical effectiveness measures (Extended Disability Status Scale (EDSS), Multiple Sclerosis Severity Scale (MSSS), Multiple Sclerosis Impact Scale (MSIS-29) and Symbol Digit Modalities Test (SDMT)) showed improvement in mean between baseline and 120 months. However, only MSSS, MSIS-29 psy-chological and SDMT were statistically significant. Over the entire observation time, 114 Serious AEs had been reported to the Swedish Medical Product Agency and included nine cases (2 fatal) of progressive multifocal leukoencephalopathy (PML) of which eight between year 2008 and 2012, and one in 2018. 17 patients died during or within 6 months of last NTZ infusion. None were judged to be directly associated with NTZ.Conclusions: NTZ is generally well tolerated with sustained effectiveness regarding cognitive, physical and psychological measures, as well as relapse-control.

- Background: Subcutaneous peginterferon beta-1a (PegIFN) was approved for relapsing-remitting multiple sclerosis (RRMS) in Europe 2014. The clinical trial program showed that PegIFN reduced the relapse rate and proportion with disability progression compared to placebo. At its launch in Sweden, PegIFN was included in the Swedish “Immunomodulation and Multiple Sclerosis Epidemiology Study” (IMSE 6), providing possibilities to track long-term effectiveness and safety in a population-based setting.Objectives: To follow-up the long-term effectiveness and safety of PegIFN treatment in Swedish patients in a real-world context.Methods: Data was obtained from the nationwide Swedish Neuro Registry (NeuroReg) between June 2015 and May 2020. Effectiveness measures were assessed using the Wilcoxon Signed Rank Test and drug survival using the Kaplan-Meier curve.Results: A total of 364 patients (78% female; 87% RRMS; mean age at treatments start 43 years) were followed up to 57 months (mean 20 months), of which 200 (55%) patients had been treated for at least 12 months. The majority of the patients had switched from other injectables (164 patients, 45%) or were treatment naïve (90 patients, 25%) prior to treatment with PegIFN. Over the dura-tion of the follow-up, 68% (247/364) patients discontinued their PegIFN treatment for various reasons (60% adverse events, 24% lack of effect) and switched mainly to rituximab (105 patients, 43%). The overall drug survival was 32%, 40% for men and 30% for women. The one- and two-year drug survival rate was 57% and 40%, respectively. The mean number of relapses were reduced from 0.35 one year before treatment start to 0.11 one year after (35% missing data). All clinical effectiveness measures (Extended Disability Status Scale (EDSS), Multiple Sclerosis Severity Scale (MSSS), Multiple Sclerosis Impact Scale (MSIS-29), European Quality of Life – 5-Dimension test (EQ-5D), Visual Analogue Score (VAS) and Symbol Digit Modalities Test (SDMT)) remained stable. Statistically significant changes were observed in SDMT (p=0.027). A total number of 18 adverse events (6 serious) were reported to Swedish Medical Product Agency.Conclusions: These findings are consistent with PegIFN being a safe disease modifying treatment, however, a relatively high pro-portion of patients switched due to adverse events. All clinical effectiveness measures remained stable in patients treated with PegIFN for at least 12 months in this nationwide population-based real-world study. Longer follow up is needed to address the long-term effectiveness.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Background: Alemtuzumab (ALZ) is an approved disease-modi-fying 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).Objectives: To track effectiveness and long-term safety of ALZ in a real-world setting, with focus on patients treated with ALZ for at least 36 months.Methods: Swedish MS patients are registered into the nationwide Swedish MS 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 patients (59% female; 95% RRMS) were included in IMSE 3 between March 2014 and June 2020. Out of 118 patients, 93 had been treated for at least 36 months (62% female), of which 10 patients had switched to another DMT. Mean age at treatment start for patients treated ⩾ 36 months was 34 years and mean treatment duration was 54 months. Mean number of drugs prior ALZ initiation was 2.4. Most of the patients (40%, n=37) switched to ALZ from natalizumab or were treatment naïve (13%, n=12) prior ALZ. The mean num-ber of relapses was reduced from 0.72 one year before ALZ initiation to 0.10 during the first treatment year, followed by 0.08 the second treatment year and 0.06 the third year of ALZ treatment (n=79, 15% missing data). In patients treated ⩾ 36 months significant improvements in mean baseline compared to 36 months were seen for MSSS (3.3 ± 2.7 to 2.3 ± 2.3, n=44) and EQ-5D (0.7 ± 0.3 to 0.8 ± 0.3, n=50), while SDMT showed significantly worsened results after 36 months (64.8 ± 17.5 to 56.2 ± 12.7, n=59). EDSS, MSIS-29 and VAS scores remained stable. A total of 36 adverse events were reported to the Swedish Medical Products Agency, 13 events were classified as serious and 23 events as non-serious. 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 36 months improved or remained stable across all effectiveness measures except SDMT. Continued follow-up is needed to address long term effectiveness and safety of ALZ.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Background: Fingolimod (FGL) is an oral disease-modifying therapy (DMT) for patients with relapsing-remitting multiple sclerosis, introduced in Sweden 2011. Already from launch, FGL was included in the Swedish “Immunomodulation and Multiple Sclerosis Epidemiology Study” (IMSE) in order to enable long-term surveillance of effectiveness and safety aspects in a large population-based cohort.Objectives: To assess the relation between Expanded Disability Status Scale (EDSS) and patient-reported outcome measurements (PROMS) in patients treated with FGL.Methods: Swedish MS patients are registered into the nation-wide Swedish MS Registry. Demographic data, EDSS and the Multiple Sclerosis Impact Scale (MSIS-29), Symbol Digit Modalities Test (SDMT), European Quality of Life - 5 Dimensions Test (EQ-5D), Visual Analog Scale (VAS) were collected for FGL patients who agreed to participate in the IMSE 2 study. Spearman rank correlation were used to determine associations between EDSS and PROMS.Results: From September 2011 until June 2020, 1670 MS patients (68% female) were included in IMSE 2. Mean age at treatment start was 39 years and mean treatment duration in the entire cohort was 44 months (M). Out of 1670 patients, 560 (63% female) had been treated with FGL for at least 60 M. Mean age was 40 years and mean treatment duration 81 M. Significant (p<0.05) correla-tions was found between EDSS and all PROMs. The strongest correlation was found between the physical component of MSIS-29 for both baseline (r=0.60, n=778) and 60 M (r=0.64, n=109). Also, for both EQ-5D and VAS, Spearman coefficient indicates a moderate correlation for baseline (EQ-5D; r=-0.48, n=744 and VAS; -0.43, n=706) and 60 M (EQ-5D; r=-0.47, n=102 and VAS; -0.48, n=102) respectively. The correlation between EDSS and SDMT and the psychological component of MSIS-29, both indi-cated a weak correlation for baseline (SDMT; r=-0.28, n=771 and MSIS-29 psychological; r=0.28, n=778). For 60 M the correla-tions were stronger and indicated a moderate correlation (SDMT; r= -0.42, n=114 and MSIS-29 psychological; r=0.33, n=109).Conclusions: The observed correlations between EDSS and PROMs in patients treated with FGL indicate a weak correlation with SDMT and the psychological component of MSIS-29. These results highlight that different scales capture different dimensions of the physical and psychological impact of MS from the patient’s perspective and have important functions which should continue to be followed.

Tidskriftsartikel (refereegranskat)abstract
- Aims: We tested whether autoantibodies to all three ZnT8RWQ variants, GAD65, insulinoma-associated protein 2 (IA-2), insulin and autoantibodies to islet cell cytoplasm (ICA) in combination with human leukocyte antigen (HLA) would improve the diagnostic sensitivity of childhood type 1 diabetes by detecting the children who otherwise would have been autoantibody-negative.Methods: A total of 686 patients diagnosed in 1996–2005 in Skåne were analyzed for all the seven autoantibodies [arginin 325 zinc transporter 8 autoantibody (ZnT8RA), tryptophan 325 zinc transporter 8 autoantibody (ZnT8WA), glutamine 325 Zinc transporter 8 autoantibody (ZnT8QA), autoantibodies to glutamic acid decarboxylase (GADA), Autoantibodies to islet-antigen-2 (IA-2A), insulin autoantibodies (IAA) and ICA] in addition to HLA-DQ genotypes.Results: Zinc transporter 8 autoantibody to either one or all three amino acid variants at position 325 (ZnT8RWQA) was found in 65% (449/686) of the patients. The frequency was independent of age at diagnosis. The ZnT8RWQA reduced the frequency of autoantibody-negative patients from 7.5 to 5.4%—a reduction by 28%. Only 2 of 108 (2%) patients who are below 5 years of age had no autoantibody at diagnosis. Diagnosis without any islet autoantibody increased with increasing age at onset. DQA1-B1*X-0604 was associated with both ZnT8RA (p = 0.002) and ZnT8WA (p = 0.01) but not with ZnT8QA (p = 0.07). Kappa agreement analysis showed moderate (>0.40) to fair (>0.20) agreement between pairs of autoantibodies for all combinations of GADA, IA-2A, ZnT8RWQA and ICA but only slight ( < 0.19) agreement for any combination with IAA.Conclusions: This study revealed that (1) the ZnT8RWQA was common, independent of age; (2) multiple autoantibodies were common among the young; (3) DQA1-B1*X-0604 increased the risk for ZnT8RA and ZnT8WA; (4) agreement between autoantibody pairs was common for all combinations except IAA. These results suggest that ZnT8RWQA is a necessary complement to the classification and prediction of childhood type 1 diabetes as well as to randomize the subjects in the prevention and intervention of clinical trials.
