Almost all currently licensed disease-modifying therapies (DMTs) for MS treatment require prolonged if not lifelong administration. Yet, as people age, the immune system has increasingly reduced responsiveness, known as immunosenescence. Many MS DMTs reduce the responsiveness of the immune system, increasing the risks for infections and possibly cancers. As people with MS (pwMS) age, it is recognized that inflammatory MS activity declines. Several studies have addressed de-escalation of DMTs for relapsing MS under special circumstances. Here, we review evidence for de-escalating DMTs as a strategy that is particularly relevant to pwMS of older age. Treatment de-escalation can involve various strategies, such as extended or reduced dosing, switching from high-efficacy DMTs having higher risks to moderately effective DMTs with lesser risks, or treatment discontinuation. Studies have suggested that for natalizumab extended dosing maintained clinical efficacy while reducing the risk of PML. Extended interval dosing of ocrelizumab mitigated the decline of Ig levels. Retrospective and observational discontinuation studies demonstrate that age is an essential modifier of drug efficacy. Discontinuation of MS treatment in older patients has been associated with a stable disease course, while younger patients who discontinued treatment were more likely to experience new clinical activity. A recently completed 2-year randomized-controlled discontinuation study in 260 stable pwMS > 55 years found stable clinical multiple sclerosis with only a small increased risk of new MRI activity upon discontinuation. DMT de-escalation or discontinuation in MS patients older than 55 years may be non-inferior to continued treatment with immunosuppressive agents having higher health risks. However, despite several small studies, a definite conclusion about treatment de-escalation in older pwMS will require larger and longer studies. Ideally, comparison of de-escalation versus continuation versus discontinuation of DMTs should be done by prospective randomized-controlled trials enrolling sufficient numbers of subjects to allow comparisons for MS patients of both sexes within age groups, such as 55-59, 60-65, 66-69, etc. Optimally, such studies should be 3 years or longer and should incorporate testing for specific markers of immunosenescence (such as T-cell receptor excision circles) to account for differential aging of individuals.

This review addresses current changes in the approach to treating patients with multiple sclerosis (MS). The widely practiced approach of utilizing agents with lower treatment efficacy (LETA) at onset with subsequent escalation has been challenged by new data suggesting that MS patients derive greater benefit when therapy is initiated with high-efficacy treatment agents (HETA). Several recent studies compared treatment efficacy and safety of early administration of HETA versus LETA. The results of randomized, double blind, phase III studies with LETA as a control arm and population-based larger and longer studies using propensity scoring, marginal structural modeling and weighted cumulative exposure analysis support the benefit of early treatment with HETA. Patients initiating their treatment with HETA, regardless of prognostic factors and MRI burden at baseline, showed significantly lower annualized relapse rate (ARR) and reduced disability progression in follow-up periods of up to 10-15 years. Moreover, the safety profile of recently approved HETA ameliorates concerns about off-target effects associated with a number of earlier high-efficacy drugs. Patient perception has also changed with an increasing preference for medication profiles that both improve symptoms and prevent disease progression. Accumulating data from randomized studies and the results of large population-based studies demonstrating short-term and longer-term patient benefits support the view that HETA should be more widely used. The adoption of early treatment with HETA capitalizes on a window of opportunity for anti-inflammatory drugs to maximally impact disease pathology and heralds a sea change in clinical practice toward pro-active management and away from a philosophy routed in generating clinical benefit as a consequence of treatment failure.

BACKGROUND: Daclizumab beta is a humanized monoclonal antibody specific for the human interleukin-2 receptor alpha chain (CD25). In two pivotal studies in relapsing multiple sclerosis (MS), patients treated with daclizumab beta exhibited lower annualized relapse rates (ARR) when compared with placebo or with intramuscular (IM) interferon beta-1a. OBJECTIVES: To determine if the efficacy of daclizumab beta demonstrated in the phase 2 SELECT study and the phase 3 DECIDE study was consistent in patient subgroups. METHODS: In the SELECT study, patients received daclizumab beta 150 or 300mg administered subcutaneously every 4 weeks for 52 weeks, and were compared with patients who received placebo. In the DECIDE study, patients received daclizumab beta 150mg administered subcutaneously every 4 weeks for 96-144 weeks, and were compared with patients who received IM interferon beta-1a 30µg. Subgroups were defined by sex, age, the number of relapses in the year before the study, disease duration, baseline disability measured by EDSS, presence of Gd-enhancing lesions, T2 hyperintense lesion volume at baseline, and previous interferon beta-1a use. RESULTS: Treatment with daclizumab beta was associated with relative lower ARR, with 95% confidence intervals (CIs) below 1 in 13 of 15 subgroups (SELECT study) compared with placebo and in all 17 subgroups compared with interferon beta-1a (DECIDE study). In 2 subgroups in the SELECT study (patients who were older than 35 years of age or who had a disease duration of 10 or more years), the rate ratio point estimate for the ARR was in favor of daclizumab beta but the 95% CI overlapped with 1. The clinical benefits in ARR achieved with daclizumab beta treatment compared with placebo or interferon beta-1a across subgroups were similarly supported by reductions in lesion activity on magnetic resonance images (MRIs). CONCLUSIONS: These findings suggest that treatment with daclizumab beta is consistently effective among clinically important patient subgroups and support its potential as a viable therapeutic option across the spectrum of relapsing MS.

BACKGROUND: In the SELECT trial, disease activity was reduced in patients with multiple sclerosis who received daclizumab high-yield process (HYP) for 52 weeks. The primary aim of the SELECTION extension study was to assess the safety and immunogenicity of extended treatment with daclizumab HYP. METHODS: A multicentre, randomised, double-blind, 52-week extension trial was done in 74 centres in the Czech Republic, Germany, Hungary, India, Poland, Russia, Ukraine, and the UK between Feb 13, 2009, and Oct 3, 2012. Eligible patients were aged 18-55 years, had relapsing-remitting multiple sclerosis, and had completed the SELECT study. Patients who received placebo in SELECT were randomly assigned (1:1) to receive 150 mg or 300 mg subcutaneous daclizumab HYP every 4 weeks for 52 weeks (treatment initiation group); those who had received daclizumab HYP were randomly assigned (1:1) to continue their present dose with (washout and re-initiation group) or without (continuous treatment group) a washout period of 20 weeks. All randomisation was done with a centralised, interactive voice-response system. Patients and personnel were masked to treatment assignment, except for the site pharmacist who prepared the study drug but had no interaction with patients. The primary endpoints were the safety and immunogenicity of daclizumab HYP. Analyses were by intention to treat. This study is registered with ClinicalTrials.gov, number NCT00870740. FINDINGS: 517 (91%) of 567 patients who completed the SELECT trial entered SELECTION, of whom 170 were in the treatment initiation group, 173 in the continuous treatment group, and 174 in the washout and re-initiation group. 11 patients in the treatment initiation group (6%), 13 in the continuous treatment group (8%), and ten in the washout and re-initiation group (6%) had any serious adverse event other than relapse of multiple sclerosis. One patient in the washout and re-initiation group (300 mg daclizumab HYP) died because of autoimmune hepatitis; a contributory role of daclizumab HYP could not be excluded. Seven patients tested positive for neutralising antidrug antibodies: one (1%) of 128 for whom data were available in the continuous treatment group (this patient also tested positive at SELECTION baseline), four (2%) in the treatment initiation group, and two (2%) of 129 in the washout and re-initiation group. INTERPRETATION: Adverse events and immunogenicity were not increased in the second year of continuous treatment with daclizumab HYP or during treatment washout and re-initiation. These results support further assessment of daclizumab HYP for relapsing-remitting multiple sclerosis. FUNDING: Biogen Idec and AbbVie Biotherapeutics.

Secondary progressive multiple sclerosis (SPMS) is a debilitating condition characterized by gradual worsening after an initial relapsing disease course. Despite the recent advances in our understanding of the disease, the diagnosis and treatment of SPMS continue to be challenging in routine clinical practice. The aim of this review article is to present the views of leading MS experts on the challenges in the diagnosis and management of SPMS and clinicians' perspectives in Central and Eastern Europe. This article also provides recommendations of MS experts to improve the situation with diagnosis and management of SPMS. Many countries within Central and Eastern Europe have high prevalence of MS (>100 per 100,000 population). Consistent with the global trend, in the absence of reliable tests or biomarkers, SPMS at early stage remains undiagnosed. Due to diagnostic uncertainty and lack of a universally accepted disease definition, clinicians rely more on retrospective analysis of the clinical symptoms to confirm the diagnosis. With the lack of awareness and poor understanding of the timing of the onset of SPMS, clinicians may tend to direct attention to relapses than the symptoms of progression, which leads to underestimation of SPMS. Although several predictors of progression to SPMS have been identified, their predictive value is highly variable. Therefore, defining the transitioning period as a separate stage of MS is essential. According to experts' opinion, frequent follow-up of patients and periodic assessment of progression are recommended for the timely identification of patients transitioning from RRMS to SPMS. MSProDiscuss Tool is an example of a quick assessment tool for identifying patients progressing from RRMS to SPMS. MS progression is usually assessed by changes in Expanded Disability Status Scale (EDSS) scores. As EDSS scores tend to fluctuate when measured in the short term (3-6 months), a longer period (≥12 months) may be needed to confirm the progression. Assessment of cognitive function is also important for evaluating secondary progression. Compartmentalization of inflammation within the central nervous system is an important reason behind the limited success of disease-modifying therapies (DMTs) for treating SPMS. Most of the DMTs fail to cross the blood-brain barrier; only 38% of the tested DMTs achieved their primary endpoint in SPMS. In Europe, siponimod is the first oral treatment for adults with active SPMS. Particularly, in Central and Eastern Europe, patients with SPMS are still being prescribed less efficacious DMTs and interferons. The absence of alternative treatments in SPMS supports the use of new products (siponimod and others); however the decision to initiate siponimod therapy in more severe patients (EDSS score of 7 or higher) should be individualized in consultation with the payers. The focus should be on early treatment initiation to delay disease progression.

BACKGROUND: In the phase 3 DEFINE and CONFIRM trials, flushing and gastrointestinal (GI) events were associated with delayed-release dimethyl fumarate (DMF; also known as gastroresistant DMF) treatment in people with relapsing-remitting multiple sclerosis (MS). To investigate these events, a post hoc analysis of integrated data from these trials was conducted, focusing on the initial treatment period (months 0-3) with the recommended DMF dosage (240 mg twice daily). METHODS: Eligibility criteria included age 18 to 55 years, relapsing-remitting MS diagnosis, and Expanded Disability Status Scale score 0 to 5.0. Patients were randomized and received treatment with placebo (n = 771) or DMF (n = 769) for up to 2 years. Adverse events were recorded at scheduled clinic visits every 4 weeks. RESULTS: The incidence of GI and flushing events was highest in the first month of treatment. In months 0 to 3, the incidence of GI events was 17% in the placebo group and 27% in the DMF group and the incidence of flushing and related symptoms was 5% in the placebo group and 37% in the DMF group. Most GI and flushing events were of mild or moderate severity and resolved during the study. The events were temporally associated with the use of diverse symptomatic therapies (efficacy not assessed) and infrequently led to DMF discontinuation. CONCLUSIONS: This integrated analysis indicates that in a clinical trial setting, GI and flushing events associated with DMF treatment are generally transient and mild or moderate in severity and uncommonly lead to treatment discontinuation.

BACKGROUND: Daclizumab high-yield process (HYP) is a humanized monoclonal antibody that binds to CD25 (alpha subunit of the interleukin-2 receptor) and modulates interleukin-2 signaling. Abnormalities in interleukin-2 signaling have been implicated in the pathogenesis of multiple sclerosis and other autoimmune disorders. METHODS: We conducted a randomized, double-blind, active-controlled, phase 3 study involving 1841 patients with relapsing-remitting multiple sclerosis to compare daclizumab HYP, administered subcutaneously at a dose of 150 mg every 4 weeks, with interferon beta-1a, administered intramuscularly at a dose of 30 μg once weekly, for up to 144 weeks. The primary end point was the annualized relapse rate. RESULTS: The annualized relapse rate was lower with daclizumab HYP than with interferon beta-1a (0.22 vs. 0.39; 45% lower rate with daclizumab HYP; P<0.001). The number of new or newly enlarged hyperintense lesions on T2-weighted magnetic resonance imaging (MRI) over a period of 96 weeks was lower with daclizumab HYP than with interferon beta-1a (4.3 vs. 9.4; 54% lower number of lesions with daclizumab HYP; P<0.001). At week 144, the estimated incidence of disability progression confirmed at 12 weeks was 16% with daclizumab HYP and 20% with interferon beta-1a (P=0.16). Serious adverse events, excluding relapse of multiple sclerosis, were reported in 15% of the patients in the daclizumab HYP group and in 10% of those in the interferon beta-1a group. Infections were more common in the daclizumab HYP group than in the interferon beta-1a group (in 65% vs. 57% of the patients, including serious infection in 4% vs. 2%), as were cutaneous events such as rash or eczema (in 37% vs. 19%, including serious events in 2% vs. <1%) and elevations in liver aminotransferase levels that were more than 5 times the upper limit of the normal range (in 6% vs. 3%). CONCLUSIONS: Among patients with relapsing-remitting multiple sclerosis, daclizumab HYP showed efficacy superior to that of interferon beta-1a with regard to the annualized relapse rate and lesions, as assessed by means of MRI, but was not associated with a significantly lower risk of disability progression confirmed at 12 weeks. The rates of infection, rash, and abnormalities on liver-function testing were higher with daclizumab HYP than with interferon beta-1a.

BACKGROUND: Demonstration of clinical benefits on disability progression measures is an important attribute of effective multiple sclerosis (MS) treatments. OBJECTIVE: Examine efficacy of daclizumab beta versus intramuscular (IM) interferon beta-1a on measures of disability progression in patient subgroups from DECIDE. METHODS: Twenty-four-week confirmed disability progression (CDP), 24-week sustained worsening on a modified Multiple Sclerosis Functional Composite (MSFCS) where 3-Second Paced Auditory Serial Addition Test was replaced by Symbol Digit Modalities Test, and proportion of patients with clinically meaningful worsening in 29-Item Multiple Sclerosis Impact Scale physical impact subscale (MSIS-29 PHYS) score from baseline to week 96 were examined in the overall population and subgroups defined by baseline demographic/disease characteristics. RESULTS: Daclizumab beta significantly reduced risk of 24-week CDP (hazard ratio (HR), 0.73; 95% confidence interval (95% CI), 0.55-0.98), risk of 24-week sustained MSFCS progression (HR, 0.80; 95% CI, 0.67-0.95), and odds of clinically meaningful worsening in MSIS-29 PHYS (odds ratio, 0.76; 95% CI, 0.60-0.95) versus IM interferon beta-1a. Point estimates showed trends favoring daclizumab beta over IM interferon beta-1a across several patient subgroups for all three outcome measures. CONCLUSION: Daclizumab beta showed consistent benefit versus IM interferon beta-1a across measures assessing patient disability/function and across a range of clinical baseline characteristics in patients with relapsing-remitting MS.

BACKGROUND: Daclizumab is a humanized monoclonal antibody against CD25 that modulates interleukin 2 signaling. The SELECT TRILOGY of clinical studies (SELECT/SELECTION/SELECTED) evaluated the safety and efficacy of daclizumab in patients with relapsing-remitting multiple sclerosis (RRMS). We report the long-term safety and efficacy of daclizumab 150 mg subcutaneous every 4 weeks in patients with RRMS in the SELECTED open-label extension study. METHODS: An interim intent-to-treat analysis of all enrolled patients was performed in January 2014 for this ongoing study. RESULTS: The SELECTED study enrolled 90% of patients who completed SELECTION. In the safety and efficacy analysis (N = 410), median treatment time in SELECTED was 25 months (range, <1-45). Adverse events (AEs) were reported in 76% of patients, serious AEs (SAEs) excluding MS relapse in 16%, and treatment discontinuation due to AEs including multiple sclerosis (MS) relapse in 12%. AEs were primarily of mild to moderate severity, and common AEs (≥10%), excluding MS relapse, were nasopharyngitis (12%) and upper respiratory tract infection (12%). Most commonly reported SAEs (in ≥3 patients), excluding MS relapses, were increased serum hepatic enzymes, pneumonia, ulcerative colitis, and urinary tract infection (<1% each). Incidences of AE groups of interest include cutaneous events (28%), cutaneous SAEs (2%), gastrointestinal SAEs (2%), hepatic SAEs, (1%) and malignancies (1%). The incidence of AEs, SAEs, and treatment-related study discontinuations did not increase over time and no deaths were reported. The adjusted annualized relapse rate (95% confidence interval (CI)) analyzed at 6-month intervals was 0.15 (0.10-0.22) for weeks 97-120 and 0.15 (0.10-0.21) for weeks 121-144. In year 3, the adjusted mean (95% CI) number of new/newly enlarging T2 hyperintense lesions was 1.26 (0.93-1.72) and the mean (median) annualized change in brain volume was -0.32% (-0.34%). CONCLUSIONS: The AE incidence did not increase with extension of therapy into year 3 in SELECTED; the safety profile was similar to that previously observed. The clinical efficacy of daclizumab was sustained over the 3 years comprising the SELECT TRILOGY, although potential selection bias cannot be excluded. TRIAL REGISTRATION: Clinicaltrials.gov NCT01051349; first registered January 15, 2010.

OBJECTIVE: To characterize effects of alemtuzumab treatment on measures of disability improvement in patients with relapsing-remitting multiple sclerosis (RRMS) with inadequate response (≥1 relapse) to prior therapy. METHODS: Comparison of Alemtuzumab and Rebif Efficacy in Multiple Sclerosis (CARE-MS) II, a 2-year randomized, rater-blinded, active-controlled, head-to-head, phase 3 trial, compared efficacy and safety of alemtuzumab 12 mg with subcutaneous interferon-β-1a (SC IFN-β-1a) 44 μg in patients with RRMS. Prespecified and post hoc disability outcomes based on Expanded Disability Status Scale (EDSS), Multiple Sclerosis Functional Composite (MSFC), and Sloan low-contrast letter acuity (SLCLA) are reported, focusing on improvement of preexisting disability in addition to slowing of disability accumulation. RESULTS: Alemtuzumab-treated patients were more likely than SC IFN-β-1a-treated patients to show improvement in EDSS scores (p < 0.0001) on all 7 functional systems. Significantly more alemtuzumab patients demonstrated 6-month confirmed disability improvement. The likelihood of improved vs stable/worsening MSFC scores was greater with alemtuzumab than SC IFN-β-1a (p = 0.0300); improvement in MSFC scores with alemtuzumab was primarily driven by the upper limb coordination and dexterity domain. Alemtuzumab-treated patients had more favorable changes from baseline in SLCLA (2.5% contrast) scores (p = 0.0014) and MSFC + SLCLA composite scores (p = 0.0097) than SC IFN-β-1a-treated patients. CONCLUSIONS: In patients with RRMS and inadequate response to prior disease-modifying therapies, alemtuzumab provides greater benefits than SC IFN-β-1a across several disability outcomes, reflecting improvement of preexisting disabilities. CLASSIFICATION OF EVIDENCE: This study provides Class I evidence (based on rater blinding and a balance in baseline characteristics between arms) that alemtuzumab modifies disability measures favorably compared with SC IFN-β-1a.
