- Introduction: Cladribine is a deoxyadenosine analogue prodrug that selectively induces immune reconstitution by targeting B- and T-lymphocytes. Cladribine tablets (CladT) are administered in two courses, 12 months apart, for patients with relapsing multiple sclerosis (RMS). CladT are included in the Swedish post-market surveillance study “Immunomodulation and Multiple Sclerosis Epidemiology”(IMSE).Objectives: To assess the safety and effectiveness of CladT with focus on patients treated at least 12 months.Methods: 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 Wilcoxon Signed Rank Test and relapse rates were tested using paired samples T-test.Results: 208 patients were included in the IMSE 10 study since the Swedish market launch in April 2018 with an overall drug survival rate of 94.2%. 12 patients discontinued treatment, of which 1 later restarted. The most common reason for discontinuation was lack of effect (83%). 21 AEs were reported of which 7 were serious. The most common AE reported were infection and infestation (8 reports).139 patients were treated for at least 12 months. 29 % of the patients was treated with CladT as their first MS drug. 19 % were treated with natalizumab and 10 % with dimethyl fumarate prior to CladT. The number of relapses decreased significantly from 249 per 1,000 patient years before treatment start to 73 during treatment. 12 patients in this cohort have experienced a relapse during treatment. Significant improvements in mean values at 12 months of treatment compared to baseline were noted for MSSS (p=0.005) and MSIS29 Psychological(p=0.033). MSIS-29 Physical showed a tendency for improvement while all other tests remained stable after one year of treatment.Lymphocyte levels decreased from a mean of 1.9 x 109/L at treat-ment start (n=80) to 1.1 x 109/L after 12 months of treatment (n=71).Conclusions: CladT treatment demonstrates clinical stability in patients treated 12 months. However, continued follow-up is needed to assess the effectiveness and safety of CladT over a longer time to assess if these results sustain after the final treatment course has been administered.

- 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 60 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) 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: 2466 DMF-treated patients were included between March 2014 and April 2021 with an overall drug survival rate of 41.2% and a mean treatment duration of 34 months. The main reasons for discontinuation were AEs (49%) and lack of effect (30%). 198 AEs were reported of which 62 were serious. For both serious and non-serious AEs reported, gastrointestinal disorders were the most common (19% and 27%, respectively).588 patients had continuous treatment for at least 60 months. This cohort had a mean age of 42.1 years and a mean treatment duration of 72.4 months. The majority (63%) had switched from interferon or glatiramer acetate and 22% were treatment naïve.Significant improvements in mean values at 60 months of treatment compared to baseline were noted for MSSS in the 60-month cohort (p<0.001). MSIS-29 Psychological showed a tendency for improvement while all other tests remained stable after 5 years of treatment. Number of relapses per 1000 patients years were improved from 198.9 before DMF treatment start to 27.9 during treatment with DMF.69 patients (12%) have discontinued DMF treatment in the 60 month cohort with a mean treatment duration of 67 months (range 60-82 months). The main reasons for discontinuation were lack of effect (26%), other reasons (26%), AEs (20%), and stable condition (15%).Conclusions: DMF demonstrates partly clinical improvements in patients treated ⩾ 60 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: Teriflunomide (TFM) is an oral therapy for relapsing-remitting multiple sclerosis (RRMS) included in the Swedish post-market surveillance study “Immunomodulation and Multiple Sclerosis Epidemiology” (IMSE).Objectives: To assess the safety and effectiveness of TFM with focus on patients treated at least 48 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) and Adverse Events (AEs) is obtained from the nationwide Swedish Neuro Registry (NeuroReg). Effectiveness measures were assessed using Wilcoxon Signed Rank Test and drug survival using Kaplan-Meier curve.Results: 645 patients were included in the IMSE 4 study from March 2014 to April 2021, 70% were female, mean age at treatment start was 46 years and mean treatment duration was 31 months. The most common prior treatment was interferon beta or glatiramer acetate (34%) and 17% were treatment naïve. One- two- and three- year drug survival rates were 74%, 59% and 49% respectively. 340 patients (53%) have discontinued treatment with main reasons for discontinuation being AEs (41%) and lack of effect (40%). Of 68 reported AEs, 20 were serious. For both serious and non-serious AEs, skin and subcutaneous tissue disorders were the most common (25% and 21%, respectively).At the cut-off date, 168 patients had been treated for at least 48 months. This cohort had a mean age of 48 years at treatment start and a mean treatment duration of 65 months. The majority (64%) had switched from interferon or glatiramer acetate and 12% were treatment naïve.Significant improvement in mean values at 48 months of treatment compared to baseline were noted for SDMT in the 48-month cohort (49.1 ± 8.2 to 50.5 ± 10.0, n=35, p=0.049) while a minor worsening were noted for EDSS (2.2 ± 1.7 to 2.6 ± 2.0, n=37, p=0.017). All other tests remained stable after 4 years of treatment.Conclusions: TMF demonstrates partly clinical improvements and stability in patients treated ⩾ 48 months but with a minor negative outcome of the EDSS scores in this cohort. A longer follow-up period is needed to assess the real-world effectiveness and safety of TMF.

- Background B-cell depleting therapies are highly efficacious in relapsing-remitting multiple sclerosis but one such therapy, rituximab, is not approved for multiple sclerosis and no phase 3 trial data are available. We therefore examined the safety and efficacy of rituximab compared with dimethyl fumarate in patients with relapsing-remitting multiple sclerosis to obtain data that might allow inclusion of rituximab in treatment guidelines. Methods RIFUND-MS was a multicentre, rater-blinded, active-comparator, phase 3, randomised controlled trial done at 17 Swedish university and community hospitals. Key inclusion criteria for participants were: age 18-50 years; relapsing-remitting multiple sclerosis or clinically isolated syndrome according to prevailing McDonald criteria; 10 years or less since diagnosis; untreated or only exposed to interferons or glatiramer acetate; and with clinical or neuroradiological disease activity in the past year. Patients were automatically randomly assigned (1:1) by the treating physician using a randomisation module in the Swedish multiple sclerosis registry, without stratification, to oral dimethyl fumarate 240 mg twice daily or to intravenous rituximab 1000 mg followed by 500 mg every 6 months. Relapse evaluation, Expanded Disability Status Scale rating, and assessment of MRI scans were done by examining physicians and radiologists masked to treatment allocation. The primary outcome was the proportion of patients with at least one relapse (defined as subacute onset of new or worsening neurological symptoms compatible with multiple sclerosis with a duration of more than 24 h and preceded by at least 30 days of clinical stability), assessed in an intention-to-treat analysis using log-binomial regression with robust standard errors. This trial is registered at ClinicalTrials.gov, NCT02746744. Findings Between July 1, 2016, and Dec 18, 2018, 322 patients were screened for eligibility, 200 of whom were randomly assigned to a treatment group (100 assigned to rituximab and 100 assigned to dimethyl fumarate). The last patient completed 24-month follow-up on April 21, 2021. 98 patients in the rituximab group and 97 patients in the dimethyl fumarate group were eligible for the primary outcome analysis. Three (3%) patients in the rituximab group and 16 (16%) patients in the dimethyl fumarate group had a protocol-defined relapse during the trial, corresponding to a risk ratio of 0.19 (95% CI 0.06-0.62; p=0.0060). Infusion reactions (105 events [40.9 per 100 patient-years]) in the rituximab group and gastrointestinal reactions (65 events [47.4 per 100 patient-years]) and flush (65 events [47.4 per 100 patient-years]) in the dimethyl fumarate group were the most prevalent adverse events. There were no safety concerns. Interpretation RIFUND-MS provides evidence that rituximab given as 1000 mg followed by 500 mg every 6 months is superior to dimethyl fumarate in preventing relapses over 24 months in patients with early relapsing-remitting multiple sclerosis. Health economic and long-term safety studies of rituximab in patients with multiple sclerosis are needed.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: The use of disease-modifying therapies (DMTs) in multiple sclerosis (MS) has been associated with reduced relapse rates and accumulation of disability. However, studies examining impact of DMT on risk of transition to secondary progressive MS (SPMS) leveraging population-based nationwide data are still rare. Here, we determine the population incidence of conversion to SPMS using two consecutive nation-wide cohorts, one immediately before and one after the introduction of DMT in Sweden.METHODS: We included two consecutive population cohorts of relapsing-remitting MS (RRMS) from the Swedish national MS register for the periods 1975-1994 (n = 2161), before DMT availability, and 1995-2011 (n = 3510), in which DMTs, mainly first generation DMT (injectables), became available and eventually were used by 70% of patients. We explored the risk of transition to SPMS as a calendar year function encompassing the two cohorts. In addition, we determined the incidence of transition to SPMS through age strata below and above 50 years in untreated and treated patient subgroups.RESULTS: The risk of conversion to SPMS (adjusted for current age, current time since onset, calendar year and sex) was significantly lower in the second compared with the first population cohort (hazard ratio 0.58; CI 0.48, 0.70). The risk of SPMS conversion per calendar year decreased by 2.6% annually (p < 0.001) after 1995. The risk of SPMS conversion increased with age until age 50. Thereafter, it was unchanged or decreased among those with early MS onset age (<35 years), but continued to increase with onset at higher age, with similar trends in treated and untreated subgroups.CONCLUSION: The incidence of SPMS conversion significantly decreased at the population level after introduction of first generation DMTs by 1995. DMT efficiency was confirmed by a downward turn of the annual trajectory of the risk of SPMS conversion after 1995. An onset age determined pattern of variable SPMS incidence in higher age appeared in both treated and untreated strata. While first generation DMT delayed conversion to SPMS, their long-term effect was only moderate.

- Background Statins are widely used to prevent cardiovascular disease (CVD). With advancing age, the risks of statins might outweigh the potential benefits. It is unclear which factors influence general practitioners' (GPs) advice to stop statins in oldest-old patients. Objective To investigate the influence of a history of CVD, statin-related side effects, frailty and short life expectancy, on GPs' advice to stop statins in oldest-old patients. Design We invited GPs to participate in this case-based survey. GPs were presented with 8 case vignettes describing patients > 80 years using a statin, and asked whether they would advise stopping statin treatment. Main Measures Cases varied in history of CVD, statin-related side effects and frailty, with and without shortened life expectancy (< 1 year) in the context of metastatic, non-curable cancer. Odds ratios adjusted for GP characteristics (ORadj) were calculated for GPs' advice to stop. Key Results Two thousand two hundred fifty GPs from 30 countries participated (median response rate 36%). Overall, GPs advised stopping statin treatment in 46% (95%CI 45-47) of the case vignettes; with shortened life expectancy, this proportion increased to 90% (95CI% 89-90). Advice to stop was more frequent in case vignettes without CVD compared to those with CVD (ORadj 13.8, 95%CI 12.6-15.1), with side effects compared to without ORadj 1.62 (95%CI 1.5-1.7) and with frailty (ORadj 4.1, 95%CI 3.8-4.4) compared to without. Shortened life expectancy increased advice to stop (ORadj 50.7, 95%CI 45.5-56.4) and was the strongest predictor for GP advice to stop, ranging across countries from 30% (95%CI 19-42) to 98% (95% CI 96-99). Conclusions The absence of CVD, the presence of statin-related side effects, and frailty were all independently associated with GPs' advice to stop statins in patients aged > 80 years. Overall, and within all countries, cancer-related short life expectancy was the strongest independent predictor of GPs' advice to stop statins.

- Recombinant human growth hormone (rhGH) has been in use for 30 years, and over that time its safety and efficacy in children and adults has been subject to considerable scrutiny. In 2001, a statement from the GH Research Society (GRS) concluded that 'for approved indications, GH is safe'; however, the statement highlighted a number of areas for on-going surveillance of long-term safety including; cancer risk, impact on glucose homeostasis and use of high dose pharmacological rhGH treatment. Over the intervening years, there have been a number of publications addressing the safety of rhGH with regard to mortality, cancer and cardiovascular risk and the need for longterm surveillance of the increasing number of adults who were treated with rhGH in childhood. Against this backdrop of interest in safety, the European Society of Paediatric Endocrinology (ESPE), the GRS and the Pediatric Endocrine Society (PES) convened a meeting to reappraise the safety of rhGH. The ouput of the meeting is a concise position statement.
