Disease-modifying therapies for relapsing multiple sclerosis reduce relapse rates by suppressing peripheral immune cells but have limited efficacy in progressive forms of the disease where cells in the central nervous system play a critical role. To our knowledge, alemtuzumab, fumarates (dimethyl, diroximel, and monomethyl), glatiramer acetates, interferons, mitoxantrone, natalizumab, ocrelizumab, ofatumumab, and teriflunomide are either limited to the periphery or insufficiently studied to confirm direct central nervous system effects in participants with multiple sclerosis. In contrast, cladribine and sphingosine 1-phosphate receptor modulators (fingolimod, ozanimod, ponesimod, and siponimod) are central nervous system-penetrant and could have beneficial direct central nervous system properties.

BACKGROUND: Ozanimod, an oral sphingosine 1-phosphate receptor 1 and 5 modulator, is approved in multiple countries for treatment of relapsing forms of MS. OBJECTIVE: To characterize long-term safety and efficacy of ozanimod. METHODS: Patients with relapsing MS who completed a phase 1‒3 ozanimod trial were eligible for an open-label extension study (DAYBREAK) of ozanimod 0.92 mg/d. DAYBREAK began 16 October 2015; cutoff for this interim analysis was 2 February 2021. RESULTS: This analysis included 2494 participants with mean 46.8 (SD 11.9; range 0.033‒62.7) months of ozanimod exposure in DAYBREAK. During DAYBREAK, 2143 patients (85.9%) had treatment-emergent adverse events (TEAEs; similar in nature to those in the parent trials), 298 (11.9%) had a serious TEAE, and 75 (3.0%) discontinued treatment due to TEAEs. Serious infections (2.8%), herpes zoster infections (1.7%), confirmed macular edema cases (0.2%), and cardiac TEAEs (2.8%) were infrequent. Adjusted annualized relapse rate was 0.103 (95% confidence interval, 0.086‒0.123). Over 48 months, 71% of patients remained relapse free. Adjusted mean numbers of new/enlarging T2 lesions/scan and gadolinium-enhancing lesions were low and similar across parent trial treatment subgroups. CONCLUSIONS: This long-term extension of ozanimod trials confirmed a favorable safety/tolerability profile and sustained benefit on clinical and magnetic resonance imaging measures of disease activity.

BACKGROUND: Fingolimod, an oral sphingosine 1-phosphate receptor immunomodulator, is approved in Europe for people with multiple sclerosis (pwMS) with highly active disease despite a full and adequate course of treatment with ≥ 1 disease-modifying therapy or patients with rapidly evolving severe relapsing-remitting MS. GOLEMS, a national, multicenter, non-interventional, single-arm, real-world study showed a favorable benefit-risk profile of 12-month treatment with fingolimod in pwMS in the Czech Republic. Here, we evaluated the long-term effectiveness and safety of fingolimod and its impact on disability progression and work capability for up to 48 months in pwMS. METHODS: The endpoints assessed were the incidence and severity of MS relapses in fingolimod-treated patients and the proportion of relapse-free patients up to 48 months of fingolimod treatment, change from baseline in the Expanded Disability Status Scale (EDSS) score, and change from baseline in work capability assessment. Efficacy outcomes were analyzed in the completed and efficacy sets, and safety was evaluated in all the enrolled patients. RESULTS: Of 240 enrolled patients, 237 were included into efficacy set. Patients with a minimum of a 12-month observation period in the core study who continued fingolimod treatment, were eligible to participate in the extension phase. Of 211 patients enrolled in extension study, 155 were evaluated in the completed set. Based on analysis of 48-month period of fingolimod treatment, 95/237 patients (40.1%) in the efficacy set, 54/155 (34.8%) in the completed set were free of relapses. The majority of relapses reported were moderate in intensity. Mean EDSS score remained stable throughout 48-month study period (Baseline, 3.4; Month 48, 3.6). No trend was observed in changes in work capability assessment or number of missed days of work. Of 240 enrolled patients, 147 (61.3%) had ≥ 1 treatment-emergent adverse event (AE) and 20 (8.3%) reported serious AEs. In total, 45 patients (18.8%) permanently discontinued treatment because of AEs related to study drug; two patients reported pregnancy after treatment initiation and subsequently discontinued the treatment; no deaths were reported. CONCLUSION: GOLEMS study demonstrated the sustained effectiveness and manageable safety profile of fingolimod under real-world conditions over 48 months in patients with MS. TRIAL REGISTRATION: Not applicable.

Secondary immunodeficiencies (SIDs) are acquired conditions that may occur as sequelae of immune therapy. In recent years a number of disease-modifying therapies (DMTs) has been approved for multiple sclerosis and related disorders such as neuromyelitis optica spectrum disorders, some of which are frequently also used in- or off-label to treat conditions such as chronic inflammatory demyelinating polyneuropathy (CIDP), myasthenia gravis, myositis, and encephalitis. In this review, we focus on currently available immune therapeutics in neurology to explore their specific modes of action that might contribute to SID, with particular emphasis on their potential to induce secondary antibody deficiency. Considering evidence from clinical trials as well as long-term observational studies related to the patients' immune status and risks of severe infections, we delineate long-term anti-CD20 therapy, with the greatest data availability for rituximab, as a major risk factor for the development of SID, particularly through secondary antibody deficiency. Alemtuzumab and cladribine have relevant effects on circulating B-cell counts; however, evidence for SID mediated by antibody deficiency appears limited and urgently warrants further systematic evaluation. To date, there has been no evidence suggesting that treatment with fingolimod, dimethyl fumarate, or natalizumab leads to antibody deficiency. Risk factors predisposing to development of SID include duration of therapy, increasing age, and pre-existing low immunoglobulin (Ig) levels. Prevention strategies of SID comprise awareness of risk factors, individualized treatment protocols, and vaccination concepts. Immune supplementation employing Ig replacement therapy might reduce morbidity and mortality associated with SIDs in neurological conditions. In light of the broad range of existing and emerging therapies, the potential for SID warrants urgent consideration among neurologists and other healthcare professionals.

IMPORTANCE: To our knowledge, the Oral Ponesimod Versus Teriflunomide In Relapsing Multiple Sclerosis (OPTIMUM) trial is the first phase 3 study comparing 2 oral disease-modifying therapies for relapsing multiple sclerosis (RMS). OBJECTIVE: To compare the efficacy of ponesimod, a selective sphingosine-1-phosphate receptor 1 (S1P1) modulator with teriflunomide, a pyrimidine synthesis inhibitor, approved for the treatment of patients with RMS. DESIGN, SETTING, AND PARTICIPANTS: This multicenter, double-blind, active-comparator, superiority randomized clinical trial enrolled patients from April 27, 2015, to May 16, 2019, who were aged 18 to 55 years and had been diagnosed with multiple sclerosis per 2010 McDonald criteria, with a relapsing course from the onset, Expanded Disability Status Scale (EDSS) scores of 0 to 5.5, and recent clinical or magnetic resonance imaging disease activity. INTERVENTIONS: Patients were randomized (1:1) to 20 mg of ponesimod or 14 mg of teriflunomide once daily and the placebo for 108 weeks, with a 14-day gradual up-titration of ponesimod starting at 2 mg to mitigate first-dose cardiac effects of S1P1 modulators and a follow-up period of 30 days. MAIN OUTCOMES AND MEASURES: The primary end point was the annualized relapse rate. The secondary end points were the changes in symptom domain of Fatigue Symptom and Impact Questionnaire-Relapsing Multiple Sclerosis (FSIQ-RMS) at week 108, the number of combined unique active lesions per year on magnetic resonance imaging, and time to 12-week and 24-week confirmed disability accumulation. Safety and tolerability were assessed. Exploratory end points included the percentage change in brain volume and no evidence of disease activity (NEDA-3 and NEDA-4) status. RESULTS: For 1133 patients (567 receiving ponesimod and 566 receiving teriflunomide; median [range], 37.0 [18-55] years; 735 women [64.9%]), the relative rate reduction for ponesimod vs teriflunomide in the annualized relapse rate was 30.5% (0.202 vs 0.290; P < .001); the mean difference in FSIQ-RMS, -3.57 (-0.01 vs 3.56; P < .001); the relative risk reduction in combined unique active lesions per year, 56% (1.405 vs 3.164; P < .001); and the reduction in time to 12-week and 24-week confirmed disability accumulation risk estimates, 17% (10.1% vs 12.4%; P = .29) and 16% (8.1% vs 9.9; P = .37), respectively. Brain volume loss at week 108 was lower by 0.34% (-0.91% vs -1.25%; P < .001); the odds ratio for NEDA-3 achievement was 1.70 (25.0% vs 16.4%; P < .001). Incidence of treatment-emergent adverse events (502 of 565 [88.8%] vs 499 of 566 [88.2%]) and serious treatment-emergent adverse events (49 [8.7%] vs 46 [8.1%]) was similar for both groups. Treatment discontinuations because of adverse events was more common in the ponesimod group (49 of 565 [8.7%] vs 34 of 566 [6.0%]). CONCLUSIONS AND RELEVANCE: In this study, ponesimod was superior to teriflunomide on annualized relapse rate reduction, fatigue, magnetic resonance imaging activity, brain volume loss, and no evidence of disease activity status, but not confirmed disability accumulation. The safety profile was in line with the previous safety observations with ponesimod and the known profile of other S1P receptor modulators.

BACKGROUND AND OBJECTIVE: Once-daily oral fingolimod is approved in the EU as escalation treatment for adult patients with highly active relapsing multiple sclerosis (MS). The efficacy and safety profiles of fingolimod have been well established in a large clinical development programme and several papers reflecting the experience with fingolimod in real-world settings have been published to date. The GOLEMS study was designed to evaluate the efficacy, safety and tolerability of fingolimod and the impact of fingolimod treatment on disability progression and work capability in patients with MS in routine clinical practice in the Czech Republic. METHODS: GOLEMS was a national, multicentre, non-interventional, single-arm study conducted to analyse the outcomes of a minimum of 12 months of fingolimod therapy on primary and secondary endpoints. The primary endpoint was to assess the proportion of relapse-free patients and severity of MS relapses in patients treated with fingolimod for 12 months. Secondary endpoints included assessment of changes in disability progression evaluated by the Expanded Disability Status Scale (EDSS) score and work capability assessment measured through voluntary completion of the WPAI-GH questionnaire. The predictive factors for relapse-free status during fingolimod treatment were also analysed. RESULTS: Of the 240 enrolled patients, 219 completed the 12-month treatment period at the time of final analysis. In the efficacy set (N = 237), the proportion of relapse-free patients increased from 47 patients (19.6 %; 95 % confidence interval [CI] 14.8-25.2) in the year before fingolimod initiation to 152 patients (64.1 %; 95 % CI 58.0-70.2) after 1 year of fingolimod treatment. Of the 85 patients who experienced at least one relapse after 1 year of fingolimod treatment, 53 (62.4 %; 95 % CI 51.7-71.9) reported only one relapse, while 25 (29.4 %; 95 % CI 20.8-39.8) and seven (8.2 %; 95 % CI 4.0-16.0) patients had ≥2 relapses, respectively. No significant changes were observed in EDSS scores over the 12-month treatment period compared with baseline. The absolute number of relapses during 2 years before initiation of fingolimod treatment and baseline EDSS scores were identified as significant independent predictors for 'being relapse-free' during the 12-month fingolimod treatment period. No trend was established in work capability or number of missed days at work due to the large proportion of missing data. Of 240 enrolled patients, 27 (11.3 %) patients discontinued the study at or before the 12-month visit, 16 (6.7 %) discontinued because of adverse events related to study drug. Only six (2.5 %) patients reported serious adverse events related to the study drug. CONCLUSION: The results confirm the favourable safety and efficacy profile of fingolimod under real-world conditions, consistent with phase III trials.

BACKGROUND: Although Fingolimod (FGD) and Natalizumab (NTZ) appear to be effective in relapsing-remitting multiple sclerosis (RRMS), they have never been directly compared in a randomized clinical trial (RCT). METHODS AND FINDINGS: We evaluated the comparative efficacy of FGD vs. NTZ using a meta-analytical approach. Data from placebo-controlled RCTs was used for indirect comparisons and observational data was utilized for head-to-head comparisons. We identified 3 RCTs (2498 patients) and 5 observational studies (2576 patients). NTZ was associated with a greater reduction in the 2-year annualized relapse rate (ARR; SMDindirect = -0.24;95% CI: from -0.44 to -0.04; p = 0.005) and with the probability of no disease activity at 2 years (ORindirect:1.82, 95% CI: from 1.05 to 3.15) compared to FGD, while no differences between the two therapies were found in the proportion of patients who remained relapse-free (ORindirect = 1.20;95% CI: from 0.84 to 1.71) and those with disability progression (ORindirect = 0.76;95% CI: from 0.48 to 1.21) at 2 years. In the analysis of observational data, we found no significant differences between NTZ and FGD in the 2-year ARR (SMD = -0.05; 95% CI: from -0.26 to 0.16), and 2-year disability progression (OR:1.08;95% CI: from 0.77 to 1.52). However, NTZ-treated patients were more likely to remain relapse-free at 2-years compared to FGD (OR: 2.19;95% CI: from 1.15 to 4.18; p = z0.020). CONCLUSIONS: Indirect analyses of RCT data and head-to-head comparisons of observational findings indicate that NTZ may be more effective than FGD in terms of disease activity reduction in patients with RRMS. However, head-to-head RCTs are required to independently confirm this preliminary observation.

IMPORTANCE: A number of officially approved disease-modifying drugs (DMD) are currently available for the early intervention in patients with relapsing-remitting multiple sclerosis (RRMS). The aim of the present study was to systematically evaluate the effect of DMDs on disability progression in RRMS. METHODS: We performed a systematic review on MEDLINE and SCOPUS databases to include all available placebo-controlled randomized clinical trials (RCTs) of RRMS patients that reported absolute numbers or percentages of disability progression during each study period. Observational studies, case series, case reports, RCTs without placebo subgroups and studies reporting the use of RRMS therapies that are not still officially approved were excluded. Risk ratios (RRs) were calculated in each study protocol to express the comparison of disability progression in RRMS patients treated with a DMD and those RRMS patients receiving placebo. The mixed-effects model was used to calculate both the pooled point estimate in each subgroup and the overall estimates. RESULTS: DMDs for RRMS were found to have a significantly lower risk of disability progression compared to placebo (RR = 0.72, 95%CI: 0.66-0.79; p<0.001), with no evidence of heterogeneity or publication bias. In subsequent subgroup analyses, neither dichotomization of DMDs as "first" and "second" line RRMS therapies [(RR = 0.72, 95% CI = 0.65-0.80) vs. (RR = 0.72, 95% = 0.57-0.91); p = 0.96] nor the route of administration (injectable or oral) [RR = 0.75 (95% CI = 0.64-0.87) vs. RR = 0.74 (95% CI = 0.66-0.83); p = 0.92] had a differential effect on the risk of disability progression. Either considerable (5-20%) or significant (>20%) rates of loss to follow-up were reported in many study protocols, while financial and/or other support from pharmaceutical industries with a clear conflict of interest on the study outcomes was documented in all included studies. CONCLUSIONS: Available DMD are effective in reducing disability progression in patients with RRMS, independently of the route of administration and their classification as "first" or "second" line therapies. Attrition bias needs to be taken into account in the interpretation of these findings.
