Background Options for non-responders to relapsing–remitting multiple sclerosis (RRMS) first-line disease-modifying therapies (DMT) are limited. We explored whether switching first-line DMT is effective. Methods Patients with RRMS who first received interferon-beta (IFNB) or glatiramer acetate (GA) were classified in three categories: DMT change because of suboptimal response, DMT change because of other reasons, and no DMT change during follow-up. Outcomes included annualized relapse rate (ARR) and relapse-free proportions. Results We identified 597 patients who initiated first-line DMT. For patients who did not change DMT ( n = 240), pre-DMT and on-DMT median ARR were 0.50 and 0 ( P < 0.0001). At 24 months, 76% (95%CI = 69–81%) of patients who did not change DMT were relapse-free. Of the 155 who switched because of suboptimal response, 101 switched to another first-line DMT. Median ARR pre-DMT, on first DMT and second DMT were: 0.50, 0.55, and 0.25 for switchers from IFNB to GA (IFNB/GA, n = 12) (pre-DMT versus first DMT: P = 0.92; first versus second DMT: P = 0.31); 0.90, 0.50, and 0 for switchers from GA to IFNB (GA/IFNB, n = 18; P = 0.19; P = 0.01); 0.50, 0.68, and 0 for switchers from an IFNB to another IFNB (IFNB/IFNB’, n = 71; P = 0.34; P = 0.02). Estimated relapse-free proportion after 24 months of treatment was 42% (95%CI=15–66%) during the period on IFNB versus 53% (95%CI = 17–80%) on GA for IFNB/GA ( P = 0.21); 12% (95%CI = 0–40%) on GA versus 87% (95%CI = 59–97%) on IFNB for GA/IFNB ( P = 0.001); and 41% (95%CI = 29–52%) on initial IFNB versus 67% (95%CI = 53–79%) on subsequent IFNB for IFNB/IFNB’ ( P = 0.0001). Conclusions Switching first-line DMT in patients with RRMS failing initial therapy may be effective in many cases.

Background Disease-modifying therapies benefit individuals with relapsing forms of multiple sclerosis, but their utility remains unclear for those without relapses. Objective To determine disease-modifying therapy use and costs in 2009, compare use in 2009 and 2000, and examine compliance with evidence-based guidelines. Methods We determined the extent and characteristics of disease-modifying therapy use by participants in the Sonya Slifka Longitudinal Multiple Sclerosis Study (Slifka) in 2000 ( n=2156) and 2009 ( n=2361) and estimated out-of-pocket and total (payer) costs for 2009. Two multivariable logistic regressions predicted disease-modifying therapy use. Results Disease-modifying therapy use increased from 55.3% in 2000 to 61.5% in 2009. In 2009, disease-modifying therapy use was reported by 76.5% of participants with relapsing-remitting multiple sclerosis, 73.2% with progressive-relapsing multiple sclerosis, 62.5% with secondary progressive multiple sclerosis, and 41.8% with primary progressive multiple sclerosis. Use was significantly associated with relapsing-remitting multiple sclerosis, shorter duration of illness, one to two relapses per year, non-ambulatory symptoms, using a cane, younger age, higher family income, and having health insurance. Average annual costs in 2009 were US$939–3101 for patients and US$16,302–18,928 for payers. Conclusion Use rates were highest for individuals with relapsing-remitting multiple sclerosis, but substantial for those with progressive courses although clinical trials have not demonstrated significant benefits for them.

Aim: The aim of the study was to assess switching disease-modifying therapy in patients with relapsing-remitting multiple sclerosis. Materials and methods: This observational single-centre study involved a retrospective evaluation of data of patients with relapsing-remitting multiple sclerosis receiving disease-modifying therapy under drug programmes reimbursed by the National Health Fund. Demographic data, the level of disability, disease activity and treatment methods were analysed with a particular emphasis on the reasons for switching the therapy. Results: Data were collected from patients with a mean age of 39.6 years, with women accounting for 68%. Therapy was switched in 32% (n = 118) of patients. In this group, 72% (n = 85) of patients modified their first-line treatment, and 28% (n = 33) required switching to a second-line drug. Treatment failure (52.5%, n = 62), followed by treatment intolerance (47.5%, n = 56) were the main reasons for switching. Patients on first line-treatment mostly required switching from interferon beta-1a, which was usually replaced with dimethyl fumarate and glatiramer acetate. The most common adverse events included skin reactions and needle fatigue, which were the most common reasons for switching treatment due to intolerance. Conclusions: The currently used immunomodulatory treatment is relatively well tolerated, and its failure is a more frequent reason for therapy switching. This indicates the need for diseasemodifying treatments that are highly effective, safe and well tolerated.

Background Disease-modifying therapies are thought to reduce the conversion rate to secondary progressive multiple sclerosis. Objective To explore the rate, chronology, and contributing factors of conversion to the progressive phase in treated relapsing–remitting multiple sclerosis patients. Methods Our study included 204 patients treated for relapsing–remitting multiple sclerosis between 1995 and 2002, prospectively followed to date. Kaplan–Meier analysis was applied to estimate the time until secondary progressive multiple sclerosis conversion, and multivariate survival analysis with a Cox regression model was used to analyse prognostic factors. Results Relapsing–remitting multiple sclerosis patients were continuously treated for 13 years (SD 4.5); 36.3% converted to secondary progressive multiple sclerosis at a mean age of 42.6 years (SD 10.6), a mean time of 8.2 years (SD 5.2) and an estimated mean time of 17.2 years (range 17.1–18.1). A multifocal relapse, age older than 34 years at disease onset and treatment failure independently predicted conversion to secondary progressive multiple sclerosis but did not influence the time to reach an Expanded Disability Status Scale of 6.0. Conclusions The favourable influence of disease-modifying therapies on long-term disability in relapsing–remitting multiple sclerosis is well established. However, the time to progression onset and the subsequent clinical course in treated patients seem similar to those previously reported in natural history studies. More studies are needed to clarify the effect of disease-modifying therapies once the progressive phase has been reached.

Abstract Background Besides coping with a disease with many uncertainties, people with relapsing-remitting multiple sclerosis face complex decisions concerning disease-modifying therapies (DMTs). In an interview study, we aimed to assess patients’ experiences with DMTs. Methods Problem-centred interviews were conducted with 50 people with relapsing-remitting multiple sclerosis in Germany using maximum variation sampling and covering all licensed DMTs. Data were analysed thematically using deductive and inductive categories. Results 47 of 50 patients had treatment with at least one of the approved DMTs. The main themes were: (1) starting a DMT, (2) switching to another DMT, (3) discontinuing a DMT, and (4) multiple sclerosis without starting a DMT. Different intercorrelated factors influenced the decision-making processes for or against a DMT. Individual experiences with DMTs in daily life contained the effort in administration, success, and failure of DMTs, coping strategies and well-being without DMTs. The decision-making process for or against a DMT and the use of those treatments can be understood as a constant, continually shifting process, complicated by different factors, which change over time. Experiences with DMTs were characterized by attempts to handle uncertainty and to (re)gain control and integrate adaptivity into one’s life. Conclusions The study provides a rich and nuanced amount of patients’ experiences with DMTs. The findings demonstrate the importance for practitioners to look at current life circumstances of patients with multiple sclerosis when recommending a DMT and to promote and enable patients to make informed decisions.
