Abstract
Multiple system atrophy is a rare, debilitating, adult-onset neurodegenerative disorder that manifests clinically as a diverse combination of parkinsonism, cerebellar ataxia, and autonomic dysfunction. It is pathologically characterized by oligodendroglial cytoplasmic inclusions containing abnormally aggregated α-synuclein. According to the updated Movement Disorder Society diagnostic criteria for multiple system atrophy, the diagnosis of clinically established multiple system atrophy requires the manifestation of autonomic dysfunction in combination with poorly levo-dopa responsive parkinsonism and/or cerebellar syndrome. Although symptomatic management of multiple system atrophy can substantially improve quality of life, therapeutic benefits are often limited, ephemeral, and they fail to modify the disease progression and eradicate underlying causes. Consequently, effective breakthrough treatments that target the causes of disease are needed. Numerous preclinical and clinical studies are currently focusing on a set of hallmarks of neurodegenerative diseases to slow or halt the progression of multiple system atrophy: pathological protein aggregation, synaptic dysfunction, aberrant proteostasis, neuronal inflammation, and neuronal cell death. Meanwhile, specific biomarkers and measurements with higher specificity and sensitivity are being developed for the diagnosis of multiple system atrophy, particularly for early detection of the disease. More intriguingly, a growing number of new disease-modifying candidates, which can be used to design multi-targeted, personalized treatment in patients, are being investigated, notwithstanding the failure of most previous attempts.

Abstract
OBJECTIVE In Iraq, a lack of evidence-based management protocols for diagnosing, treating, and managing multiple sclerosis (MS) poses risks of suboptimal outcomes and clinical practice variability and potential harm to the patients. This study aimed to develop consensus recommendations regarding the diagnosis and management of MS in Iraq, specifically focusing on treatment-naïve patients, suboptimal responders, and women of childbearing age during preconception, pregnancy planning, and lactation. A survey was conducted to collect feedback from a panel of ten key opinion leaders (KOLs), who evaluated and discussed the statements to determine agreement levels. The mini-Delphi method was employed to establish a consensus on the management recommendations, and a meeting was held to analyze the responses and ensure that the recommendations were based on current evidence and followed a consensus-driven approach. RESULTS The Revised McDonald Criteria is recommended for MS diagnosis, which includes evidence of dissemination of disease characteristics in space and time. Disease activity and progression can be monitored using relapses, MRI activity, and short-term disability progression. Experts suggest initiating treatment at diagnosis using higher efficacy medications, such as cladribine, ocrelizumab, natalizumab, or rituximab, for patients with high disease activity after careful risk stratification. Injectable interferon preparations have a tolerable risk profile but have drawbacks, such as the route and frequency of administration. Overall, disease-modifying therapies (DMTs) have shown efficacy in reducing relapse rates and short-term disability. CONCLUSION This article presents expert panel recommendations for managing MS in Iraq, taking into account international guidelines, medication updates, and local resources. However, practical questions remain regarding the real-world use of disease-modifying therapies (DMTs). Personalizing treatment based on disease severity, prognosis, and individual risk factors while adhering to guidelines is crucial. A collaborative approach between healthcare providers and patients, considering individual preferences, is vital for achieving treatment goals.

Abstract
Multiple sclerosis (MS) is characterized by progressive neuroinflammation and neurodegeneration from disease onset that, if left untreated, can result in the accumulation of irreversible neurological disability. Early intervention with high-efficacy therapies (HETs) is increasingly recognized as the best strategy to delay or mitigate disease progression from the earliest stages of the disease and to prevent long-term neurodegeneration. Although there is growing clinical and real-world evidence supporting early HET intervention, foregoing this strategy in favor of a traditional escalation approach prioritizing lower-efficacy disease-modifying therapies remains a common approach in clinical practice. This review explores potential health care professional- and patient-related barriers to the early use of HETs in patients with MS in the United States. Barriers can include regulatory and reimbursement restrictions; knowledge gaps and long-term safety concerns among health care professionals; and various individual, cultural, and societal factors affecting patients. Potential strategies for overcoming these barriers and encouraging early HET use are proposed.

Abstract
PURPOSE OF REVIEW This review summarizes previous and ongoing neuroprotection trials in multiple system atrophy (MSA), a rare and fatal neurodegenerative disease characterized by parkinsonism, cerebellar, and autonomic dysfunction. It also describes the preclinical therapeutic pipeline and provides some considerations relevant to successfully conducting clinical trials in MSA, i.e., diagnosis, endpoints, and trial design. RECENT FINDINGS Over 30 compounds have been tested in clinical trials in MSA. While this illustrates a strong treatment pipeline, only two have reached their primary endpoint. Ongoing clinical trials primarily focus on targeting α-synuclein, the neuropathological hallmark of MSA being α-synuclein-bearing glial cytoplasmic inclusions. The mostly negative trial outcomes highlight the importance of better understanding underlying disease mechanisms and improving preclinical models. Together with efforts to refine clinical measurement tools, innovative statistical methods, and developments in biomarker research, this will enhance the design of future neuroprotection trials in MSA and the likelihood of positive outcomes.

Abstract
Multiple sclerosis (MS) is a chronic, progressive, inflammatory disorder of the central nervous system. Relapsing-remitting MS (RRMS), the most common form of the disease, is characterized by transient neurological dysfunction with concurrent accumulation of disability. Over the past three decades, disease-modifying therapies (DMTs) capable of reducing the frequency of relapses and slowing disability worsening have been studied and approved for use in patients with RRMS. The first DMTs were interferon-betas (IFN-βs), which were approved in the 1990s. Among them was IFN-β-1a for subcutaneous (sc) injection (Rebif®), which was approved for the treatment of MS in Europe and Canada in 1998 and in the USA in 2002. Twenty years of clinical data and experience have supported the efficacy and safety of IFN-β-1a sc in the treatment of RRMS, including pivotal trials, real-world data, and extension studies lasting up to 15 years past initial treatment. Today, IFN-β-1a sc remains an important therapeutic option in clinical use, especially around pregnancy planning and lactation, and may also be considered for aging patients, in which MS activity declines and long-term immunosuppression associated with some alternative therapies is a concern. In addition, IFN-β-1a sc is used as a comparator in many clinical studies and provides a framework for research into the mechanisms by which MS begins and progresses.

Abstract
With evolving diagnostic criteria and the advent of new oral and parenteral therapies for Multiple Sclerosis (MS), most current diagnostic and treatment algorithms need revision and updating. The diagnosis of MS relies on incorporating clinical and paraclinical findings to prove dissemination in space and time and exclude alternative diseases that can explain the findings at hand. The differential diagnostic workup should be guided by clinical and laboratory red flags to avoid unnecessary tests. Appropriate selection of MS therapies is critical to maximize patient benefit. The current guidelines review the current diagnostic criteria for MS and the scientific evidence supporting treatment of acute relapses, radiologically isolated syndrome, clinically isolated syndrome, relapsing remitting MS, progressive MS, pediatric cases and pregnant women. The purpose of these guidelines is to provide practical recommendations and algorithms for the diagnosis and treatment of MS based on current scientific evidence and clinical experience.

Abstract
BACKGROUND Active relapsing-remitting (RR) and secondary progressive (SP) multiple sclerosis (MS) are currently defined as "relapsing MS" (RMS). The aim of this cross-sectional study was to assess drivers of treatment switches due to clinical relapses in a population of RMS patients collected in the Italian MS and Related Disorders Register (I-MS&RD). METHODS RRMS and SPMS patients with at least one relapse in a time window of 2 years before of data extraction were defined as RMS. Factors associated with disease-modifying therapy (DMT) switching due to clinical activity were assessed through multivariable logistic regression models in which treatment exposure was included as the last recorded DMT and the last DMT's class [moderate-efficacy (ME), high-efficacy (HE) DMTs and anti-CD20 drugs]. RESULTS A cohort of 4739 RMS patients (4161 RRMS, 578 SPMS) was extracted from the I-MS&RD. A total of 2694 patients switching DMTs due to relapses were identified. Switchers were significantly (p < 0.0001) younger, less disabled, more frequently affected by an RR disease course in comparison to non-switcher patients. The multivariable logistic regression models showed that Alemtuzumab (OR 0.08, 95% CI 0.02-0.37), Natalizumab (0.48, 0.30-0.76), Ocrelizumab (0.1, 0.02-0.45) and Rituximab (0.23, 0.06-0.82) exposure was a protective factor against treatment switch due to relapses. Moreover, the use of HE DMTs (0.43, 0.31-0.59), especially anti-CD20 drugs (0.14, 0.05-0.37), resulted to be a protective factor against treatment switch due to relapses in comparison with ME DMTs. CONCLUSIONS More than 50% of RMS switched therapy due to disease activity. HE DMTs, especially anti-CD20 drugs, significantly reduce the risk of treatment switch.

Abstract
OBJECTIVES We evaluate the potential clinical and cost impacts of discontinuing disease-modifying therapy (DMT) in people with multiple sclerosis (PwMS) when age-related immunosenescence can reduce DMT efficacy while increasing associated risks. METHODS A Markov model simulated clinical and cost impacts to the patient and payers when a proportion of eligible patients with relapsing remitting multiple sclerosis (RRMS) discontinue DMT. Eligibility was defined as age >55 years, an RRMS diagnosis of >5 years, and no history of relapses for 5 years. Increasing the proportion of eligible patients willing to discontinue therapy was also modeled. Clinical and cost inputs were from published literature. RESULTS Difference in EDSS progression between eligible patients who did and did not attempt discontinuation was not significant. After 1 year of eligibility, per-patient costs were $96k lower in the cohort that attempted discontinuation; however a higher proportion of relapses were seen in this group. When the proportion of patients willing to discontinue DMT increased, clinical findings remained consistent while the average cost per patient decreased. CONCLUSION While there are increased clinical and cost benefits as more eligible patients attempt discontinuation, the risk of relapses can increase. Timely disease monitoring is required to manage safe DMT discontinuation.

Abstract
Objective Our objective was to uncover the predictive factors that can help anticipate the malignant progression of individuals with Relapsing-Remitting Multiple Sclerosis (RRMS). Additionally, we sought to analyze and compare the response to treatment between patients with benign and malignant forms of RRMS. Methods This cohort study included RRMS patients categorized as benign (≥10 years since disease onset, Expanded Disability Status Scale (EDSS) ≤ 1) or malignant (≤5 years since disease onset, EDSS ≥6). Patients' data, including demographics, medical history, treatment, and MRI (Magnetic Resonance Imaging) scans, were collected and statistically analyzed. Results Among the 254 patients diagnosed with RRMS, 174 were found to have benign RRMS, while the remaining 80 were diagnosed with malignant RRMS. Notably, patients with malignant RRMS exhibited a significantly higher mean age of onset (32.00 ± 7.96 vs. 25.70 ± 17.19; P < 0.001) and a greater prevalence of males (40% vs. 18.4%; P = 0.014). Additionally, within the initial five years of diagnosis, patients with malignant RRMS experienced a higher number of relapses (median: 4 vs. 2; P < 0.001) and hospitalizations (median: 2 vs. 1; P = 0.006) compared to those with benign RRMS. Clinical presentations of malignant RRMS were predominantly characterized by multifocal attacks, whereas unifocal attacks were more prevalent in patients with benign RRMS. MRI scans revealed that malignant RRMS patients displayed a higher burden of plaques in the infratentorial and cord regions, as well as a greater number of black hole lesions. Conversely, benign RRMS patients exhibited a higher number of Gadolinium-enhanced lesions. Utilizing Disease-Modifying Therapies (DMTs) with an escalating approach has shown effectiveness in managing benign RRMS. However, it has proven insufficient in addressing malignant RRMS, resulting in frequent transitions to higher-line DMTs. As a result, it places a considerable burden on patients with malignant RRMS, consuming valuable time and resources, and ultimately yielding subpar outcomes. Conclusion Our study identifies prognostic factors for malignant progression in RRMS, including older age of onset, male gender, increased relapses and hospitalizations, multifocal attacks, higher plaque load, and black hole lesions. The current escalation strategy for DMTs is insufficient for managing malignant RRMS, requiring alternative approaches for improved outcomes. In other words, MS is a spectrum rather than a single disease, and some patients progress to a malignant phenotype of MS that is not effectively treated by the current approach.

Abstract
Multiple sclerosis has a 3:1 female-to-male predominance and commonly presents in young adult women. The hormonal changes in women throughout their lifetime do affect the underlying pathology of multiple sclerosis, and the needs of women therefore change with age. Although multiple sclerosis does not adversely affect fertility or pregnancy, there are many factors to consider when caring for women throughout family planning, pregnancy, and the postpartum period. The care of these women and complex decisions regarding disease-modifying therapy use in family planning should be individualized and comprehensive.

Abstract
BACKGROUND There is a lack of knowledge of disease course, prognosis, comorbidities and potential treatments of elderly MS patients. OBJECTIVE To characterize the disease course including disability progression and relapses, to quantify the use of DMTs and to identify comorbidities and risk factors for progression in elderly multiple sclerosis (MS) patients. METHODS This is a retrospective study of 1200 Austrian MS patients older than 55 years as of May 1st, 2017 representing roughly one-third of all the MS patients of this age in Austria. Data were collected from 15 MS centers including demographics, first symptom at onset, number of relapses, evolvement of disability, medication, and comorbidities. RESULTS Median observation time was 17.1 years with 957 (80%) relapsing and 243 (20%) progressive onsets. Average age at diagnosis was 45 years with a female predominance of 71%. Three-hundred and twenty-six (27%) patients were never treated with a DMT, while most treated patients received interferons (496; 41%) at some point. At last follow-up, 420 (35%) patients were still treated with a DMT. No difference was found between treated and never-treated patients in terms of clinical outcome; however, patients with worse disability progression had significantly more DMT switches. Pyramidal onset, number of comorbidities, dementia, epilepsy, and psychiatric conditions as well as a higher number of relapses were associated with worse outcome. The risk of reaching EDSS 6 rose with every additional comorbidity by 22%. In late and very-late-onset MS (LOMS, VLOMS) time to diagnosis took nearly twice the time compared to adult and early onset (AEOMS). The overall annualized relapse rate (ARR) decreased over time and patients with AEOMS had significantly higher ARR compared to LOMS and VLOMS. Four percent of MS patients had five medications or more fulfilling criteria of polypharmacy and 20% of psychiatric drugs were administered without a matching diagnosis. CONCLUSIONS In this study, we identified number of comorbidities, pyramidal and cerebellar signs, and a higher number of relapses as unfavorable prognostic factors in elderly MS patients filling gaps of knowledge in patients usually underrepresented in clinical trials and may guide future therapeutic studies.

Abstract
Open-label extension (OLE) studies help inform long-term safety and efficacy of disease-modifying therapies in multiple sclerosis (MS). We report exploratory analyses from a phase 2 trial on the longest follow-up to date of ocrelizumab-treated patients with relapsing-remitting MS (RRMS). The primary treatment period (PTP) comprised four 24-week treatment cycles; participants were randomized to double-blind ocrelizumab (2000 mg or 600 mg), placebo, or interferon β-1a (open label) for one cycle, then dose-blinded ocrelizumab 1000 mg or 600 mg for the remaining cycles. The PTP was followed by consecutive assessed and unassessed treatment-free periods (TFPs) and then the OLE (ocrelizumab 600 mg every 24 weeks). Safety and efficacy were prospectively assessed. Of 220 participants randomized, 183 (84%) completed the PTP. After the TFP, 103 entered OLE (median OLE ocrelizumab exposure 6.5 years). Most common adverse events across all periods were infusion-related reactions. MRI activity, annualized relapse rate, and confirmed disability progression (CDP) rates remained low throughout. During the assessed TFP, there was a trend toward less and later B-cell repletion, and later CDP, for patients randomized to ocrelizumab; MRI activity was observed in 16.3% of patients, the earliest 24 weeks after the last ocrelizumab dose. This is the longest follow-up of ocrelizumab-treated patients with RRMS, with no new safety signals emerging during an observation period from 2008 to 2020. Results reinforce the sustained efficacy of long-term ocrelizumab. Reduced disease activity was maintained following interruption of 6-month dosing cycles, with no evidence of rebound.

Abstract
Randomized controlled trials (RCTs) are essential for regulatory approval of disease-modifying therapies (DMTs), yet their strict selection criteria often lead to limited generalizability. Observational studies using real-world data (RWD) allow for more inclusive heterogeneous cohorts resulting in higher external validity to inform treatment practices. As reviewed in this article, well-designed comparative effectiveness studies are an important application of RWD. Although, like RCTs, observational studies have their own set of limitations, including various biases that may confound results, advanced statistical methods can mitigate many of these limitations. A focus on personalized treatment will continue to add value to individualize MS care.

Abstract
BACKGROUND Autologous haematopoietic stem cell transplantation (AHSCT) is a highly effective one-off treatment for relapsing-remitting multiple sclerosis (RR-MS), potentially representing an optimal front-loading strategy for costs. OBJECTIVE Exploring cost/effectiveness of AHSCT and high-efficacy disease-modifying treatments (HE-DMTs) in RR-MS, estimating costs at our centre in Italy, where National Health Service (NHS) provides universal health coverage. METHODS Costs (including drugs, inpatient/outpatient management) for treatment with AHSCT and HE-DMTs were calculated as NHS expenditures over 2- and 5-year periods. Cost-effectiveness for each treatment was estimated as "cost needed to treat" (CNT), i.e. expense to prevent relapses, progression, or disease activity (NEDA) in one patient over n-years, retrieving outcomes from published studies. RESULTS Costs of AHSCT and HE-DMTs were similar over 2 years, whereas AHSCT was cheaper than most HE-DMTs over 5 years (€46 600 vs €93 800, respectively). When estimating cost-effectiveness of treatments, over 2 years, mean CNT of HE-DMTs for NEDA was twofold that of AHSCT, whereas it was similar for relapses and disability. Differences in CNT were remarkable over 5 years, especially for NEDA, being mean CNT of HE-DMTs €382 800 vs €74 900 for AHSCT. CONCLUSIONS AHSCT may be highly cost-effective in selected aggressive RR-MS. Besides priceless benefits for treated individuals, cost-savings generated by AHSCT may contribute to improving healthcare assistance at a population level.

Abstract
BACKGROUND Long-term population-based safety studies are needed to investigate cancer outcomes in people with multiple sclerosis (MS) treated with modern disease-modifying therapy (DMT). OBJECTIVES To investigate if exposure to DMT increases the risk of invasive cancer in MS. METHODS We used population-based administrative health data from Alberta, Canada between 2008 and 2018. DMT exposure was defined in two ways: first as exposure to any DMT, and second by DMT type (modulating, sequestering, depleting). Study outcome was time to first diagnosis of invasive cancer. Cancer risk was compared to the general population using standardized incidence ratios (SIRs) and to the unexposed MS cases using hazard ratios (HRs). RESULTS The analysis included 14,313 MS cases: 5,801 (40.5 %) were exposed to DMT. Median (interquartile range) follow-up was 8.4 (4.3, 10.4) years. Compared to the general population, there was no difference in cancer risk for the overall MS population (SIR: 0.94, 95 % confidence interval [CI]: 0.87, 1.02) or the DMT-exposed MS cases (SIR: 0.89; 95 % CI: 0.75, 1.05). Compared to unexposed MS cases, we found an interaction with age for exposure to any DMT (p = 0.001) and modulating DMT (p = 0.001), indicating that a difference in the risk of cancer associated with DMT depends on age. Cancer risk was not associated with exposure to sequestering DMT (HR: 1.28, 95 % CI: 0.78, 2.08) or depleting DMT (HR: 2.29, 95 % CI: 0.86, 6.14). CONCLUSIONS Cancer risk for MS patients was similar to the general population. In the MS population, the age-dependent effect of DMT for cancer risk suggests a higher risk of cancer with age 62 or older and a protective effect at younger age. Further investigation is required to clarify whether the interaction between DMT exposure and age is a causal effect.

Abstract
BACKGROUND Changes in immunoglobulin (Ig) levels may occur in association with various drugs targeting immunity, including those used to treat multiple sclerosis (MS). However, influence of high-dose corticosteroids (CS) is poorly described. OBJECTIVE To describe influence of disease-modifying drugs (DMD) and CS on the Ig levels. METHODS Monocentric retrospective study examining changes in Ig levels in relation with CS intake in a series of 304 consecutive MS patients (and 1204 samples) followed or hospitalized for 7 years in a single centre. Ig levels are routinely collected in MS patients followed in our centre. RESULTS IgG levels were significantly lower in MS patients exposed to CS infusion during the last 24 months. IgG levels were also lower in DMD-treated patients exposed to CS. DMD-specific decrease of IgM levels was confirmed in interaction with CS. CONCLUSION Stratification by CS exposure suggested that a decrease in Ig levels occurring during DMD treatment was strongly associated with CS infusion. The strong and persistent effect of CS on Ig levels could be a hidden variable and should be considered in further studies targeting Ig levels.

Abstract
BACKGROUND Multiple sclerosis (MS) management varies markedly between different countries of the Middle East and North Africa (MENA) region based on the availability and accessibility of disease-modifying therapies (DMTs). OBJECTIVE To evaluate the accessibility to DMTs in each MENA country, identify barriers to treatment and make recommendations for improved access to DMTs across the region. METHODS This is a descriptive, survey-based study whereby we extracted data collected, between October 2019 and April 2020, for countries in the MENA region by the Multiple Sclerosis International Federation (MSIF) through their Atlas of MS survey. RESULTS 16 out of 19 countries in the MENA region were included in this study. Sudan and Syria did not have any originator DMTs approved. Interferons were the most widely low-efficacy originator approved DMTs. Three countries did not have any high efficacy DMTs approved. Moreover, follow-on DMTs were approved in half (50%) of the countries. Cost of treatment was the most important barrier, reported in nearly half (47%) of the MENA countries. CONCLUSION Although most MENA countries have access to DMTs, more than half of countries report problems with treatment continuation, highlighting the need for a targeted regional strategy to address the variations in access to MS treatments.

Abstract
BACKGROUND Changes in immunoglobulin (Ig) levels may occur in association with various drugs targeting immunity, including disease-modifying drugs (DMD) and corticosteroids (CS) used to treat multiple sclerosis (MS). However, kinetics of Ig levels during the natural history of MS is poorly described. OBJECTIVE To describe the natural history of the Ig levels in MS. METHODS Monocentric retrospective study examining changes in Ig levels in relation with CS intake in a series of 304 consecutive MS patients (and 1204 samples) followed or hospitalized for 7 years in a single centre. Ig levels are routinely collected in MS patients followed in our centre. RESULTS IgG levels were higher in samples taken at diagnosis than in those taken after the onset of MS symptoms. This effect was also observed in patients remaining free of DMD or CS since onset. On the other hand, overall Ig levels remained stable across fixed time points ranging from 1 to 20 years after onset CONCLUSION: An unanticipated finding of this study was the transient higher IgG levels in samples taken at onset, which suggests that strong inflammatory processes may occur early.

Abstract
INTRODUCTION Prior research has demonstrated that early treatment with high-efficacy disease-modifying therapies (DMTs), including ocrelizumab (OCR), can reduce relapses and delay disease progression among persons with multiple sclerosis (pwMS) compared with escalation from low-/moderate-efficacy DMTs. However, there is a lack of research examining the impact of early use of OCR on real-world clinical and economic outcomes. This study aimed to evaluate differences in events often associated with a relapse (EOAR) as well as non-DMT healthcare resource use (HCRU) and costs among pwMS who received OCR as a first-line treatment compared with later-line treatment after diagnosis. METHODS Newly diagnosed adult pwMS were selected from deidentified Optum Market Clarity claims data (study period: January 1, 2015-June 30, 2021). All pwMS were required to have initiated OCR after diagnosis and have 12 months of continuous eligibility prior to diagnosis. The index date was the date of initiation of the first-line DMT after diagnosis. pwMS who initiated OCR as first-line (1L OCR cohort) or a second- or later-line treatment (2L + OCR cohort) were matched 1:1 based on length of continuous eligibility after the first-line DMT and weighted using stabilized inverse probability of treatment. In the follow-up period, differences in outcomes, including annualized EOAR, non-DMT HCRU and costs, were evaluated for pwMS in the 1L vs. 2L + OCR cohorts. RESULTS The sample included 748 pwMS. During the follow-up period, pwMS in the 1L OCR cohort had a significantly lower annual rate of EOAR compared with pwMS in the 2L + OCR cohort (0.37 vs. 0.56; difference: 0.20 [95% CI 0.08, 0.32]). pwMS in the 1L OCR cohort had a significantly lower probability of any hospitalization within 1 year, fewer non-DMT outpatient visits and lower all-cause and MS-related, non-DMT costs compared with pwMS in the 2L + OCR cohort. CONCLUSIONS First-line initiation OCR was associated with improvements in clinical and non-DMT economic outcomes compared with later-line initiation of OCR, suggesting that early initiation may benefit both patients and the healthcare system.

Abstract
BACKGROUND Relapsing multiple sclerosis (MS) is an inflammatory, demyelinating, neurodegenerative disease of the central nervous system that causes episodes of neurological dysfunction (relapse) alternating with variable intervals of stability. Disease-modifying therapies (DMTs) aim to reduce the rate of relapse and slow disease progression in people with MS, particularly in those with relapsing MS. Ofatumumab is a fully human anti-CD20 monoclonal antibody approved to treat patients with relapsing forms of MS. This study describes the demographics, clinical characteristics, and prior DMT use of patients with at least one ofatumumab prescription claim following approval by the United States (US) Food and Drug Administration (FDA). Understanding ofatumumab utilization patterns and patient characteristics can help define the journey of patients with MS and aid future clinical decision-making. METHODS This retrospective study is based on data from IQVIA's Longitudinal Prescription Data (LRx) and Medical Claims (Dx) databases in the US, collected between August 01, 2019 and May 31, 2021. The index date was defined as the date of the first ofatumumab prescription. The pre-index period was defined as the 12 months prior to the index date. Adult patients (aged ≥18 years) with a diagnosis of MS and at least one prescription for ofatumumab between August 2020 and May 2021 in the LRx database were included. Only patients with at least one medical claim in the Dx database and a diagnosis of MS 24 months prior to the index date were included. Descriptive analyses were conducted 3, 6, and 9 months after FDA approval. RESULTS Overall, 3,600 patients with a prescription for ofatumumab were identified in the LRx claims database, and 2,101 patients remained in the study after inclusion and exclusion criteria had been applied. At the 9-month post-approval time point, patients with ofatumumab claims were characterized as primarily female (74%) and middle-aged (median age: 48 years); two-thirds (64.7%) had a mild MS disability level. Patients were otherwise generally healthy with limited comorbid conditions. Most patients (81.7%) in the study did not experience relapse during the pre-index period. DMT-naïve patients who were prescribed ofatumumab at 3, 6, and 9 months post-approval accounted for 46.9%, 54.8%, and 58.4% of the study population, respectively. Over time, this increase in DMT-naïve ofatumumab initiators was statistically significant (p = 0.0003). Among patients who had been treated with DMTs during the previous year, most had taken them orally (50.6%), some had received them via intravenous infusion (32.2%), and some via subcutaneous/intramuscular injection (21.1%). Intravenous ocrelizumab was the most common DMT switch observed (n = 205, 23.4%) among these patients. CONCLUSION This real-world study is the first to describe patients treated with ofatumumab since FDA approval during the COVID-19 pandemic. The majority of patients in this study were middle-aged women with mild MS symptoms. Ofatumumab was increasingly used as a first-line DMT. Additionally, a number of patients aged ≥55 years (beyond the trial population) used ofatumumab, which may suggest expanding clinician confidence in the safety and clinical utility of ofatumumab therapy. However, future long-term observational studies are needed to confirm these results.

Abstract
BACKGROUND AND PURPOSE disease-modifying treatments (DMT) for Multiple Sclerosis (MS) have expanded in recent years making the shared-decision process challenging. Moreover, no head-to-head studies are available within the first-line options. Our aim is to compare therapeutic persistence within first-line DMT: teriflunomide (TER), dimethyl fumarate (DMF), and injectable drugs (INJ) in a real-world setting. METHODS Retrospective observational study analyzing diagnosed with Relapsing-Remitting Multiple Sclerosis (RRMS) who started DMT between January 2015 and April 2022 (TER=117, DMF=117, INJ=123). Clinical, radiological, and demographic variables were collected. The primary outcome was the median time to discontinuation of any DMT. Dropout was defined as discontinuation for 6 months for any reason. RESULTS Of the total of 357 patients, 155 withdraw with a median time-to-discontinuation of 1.427 years (IQR 2.410). The discontinuation rate was higher in the injectable group, 49.6%; compared to teriflunomide 40.2%, and dimethyl fumarate 39.8% (p = 0.201). The most frequent reason of discontinuation differs within groups (lack of efficacy in TER, 63.8%, and adverse effects in DMF and INJ (40.4% and 40.9% respectively). No difference in persistence was observed between DMT (p = 0.30). After 2018 there has been a tendency to treat in a quick and early manner (lower EDSS; relapse rate and number of naïve patients), statistically significant for TER (p = 0.005, p = 0.010, and p = 0.045). CONCLUSIONS Our study demonstrated no differences in persistence between the actual first-line DMT in a real-world setting, although a trend to favor oral-DMT was seen. Reasons for discontinuation differs within groups.

Abstract
BACKGROUND Previously, several studies investigated the effect of cladribine among patients with multiple sclerosis (MS) as a treatment option. Due to the contradictory results of previous studies regarding the efficacy and safety of cladribine in the MS population, we aimed to conduct a systematic review and meta-analysis by including clinical trials and observational studies in terms of having more confirmative results to make a general decision. METHODS The three databases including PubMed, Scopus, and Web of Science were comprehensively searched in May 2022. We included the studies that investigated the efficacy and safety of cladribine in patients with MS. Eligible studies have to provide sufficient details on MS diagnosis and appropriate follow-up duration. We investigated the efficacy of cladribine with several outcomes including Expanded Disability Status Scale (EDSS) change, progression-free survival (PFS), relapse-free survival (RFS), and MRI-free activity survival (MFAS). RESULTS After two-step reviewing, 23 studies were included in our qualitative and quantitative synthesis. The pooled SMD for EDSS before and after treatment was - 0.54 (95%CI: - 1.46, 0.39). Our analysis showed that the PFS after cladribine use is 79% (95%CI 71%, 86%). Also, 58% of patients with MS who received cladribine remained relapse-free (95%CI 31%, 83%). Furthermore, the MFAS after treatment was 60% (95%CI 36%, 81%). Our analysis showed that infection is the most common adverse event after cladribine treatment with a pooled prevalence of 10% (95%CI 4%, 18%). Moreover, the pooled prevalence of infusion-related adverse events was 9% (95%CI 4%, 15%). Also, the malignancies after cladribine were present in 0.4% of patients (95%CI 0.25%, 0.75%). CONCLUSION Our results showed acceptable safety and efficacy for cladribine for the treatment of MS except in terms of reducing EDSS. Combination of our findings with the results of previous studies which compared cladribine to other disease-modifying therapies (DMTs), cladribine seems to be a safe and effective drug in achieving better treatment for relapsing-remitting MS (RRMS) patients.

Abstract
BACKGROUND Cholesterol and lipids are essential components of nerve cells. Myelin synthesis and stabilization is a cholesterol-dependent process. It has been shown in several studies that high plasma cholesterol levels may be associated with clinical deterioration in Multiple Sclerosis (MS). There is scarce information about the effects of disease-modifying treatment (DMTs) on lipid profile. In this study, we aimed to investigate the effect of DMTs on plasma lipid profiles in MS patients. METHOD The records of 380 MS patients who were still under follow-up were analyzed in terms of age, sex, disease duration, EDSS scores, serum lipid levels, and used DMTs. The data of patients receiving Interferon (n = 53), Glatiramer acetate (n = 25), Fingolimod (n = 44), Teriflunomide (n = 24), Dimethyl fumarate (n = 7) and Ocrelizumab (n = 14) were compared with the data of control group (n = 53). RESULTS A total of 220 patients, 157 women, and 63 men, were included in the study. The average age of the participants in the study was 39.83 ± 10.21 years, mean disease duration was 8.45 ± 6.56 years, and the EDSS score was 2.25 ± 1.97. Although, Lipid parameters were higher in MS patients using Fingolimod the difference cannot reach the statistical significance. CONCLUSION No significant relationship was found between the DMTs that MS patients had been using for the last six months and their cholesterol levels.

Abstract
BACKGROUND Multiple sclerosis is an autoimmune chronic inflammatory disease characterized by selective destruction of myelin in the CNS neurons (including optic nerve). It was first described in the 19th century and remained elusive owing to the disease's unique relapsing and remitting course. The widespread and debilitating prevalence of multiple sclerosis (MS) has prompted the development of various treatment modalities for its effective management. METHODS AND OBJECTIVES A literature review was conducted using the electronic databases PubMed and Google Scholar. The main objective of the review was to compile the advances in pathogenesis, classifications, and evolving treatment modalities for MS. RESULTS The understanding of the pathogenesis of MS and the potential drug targets for its precise treatment has evolved significantly over the past decade. The experimental developments are also motivating and present a big change coming up in the next 5 years. Numerous disease-modifying therapies (DMTs) have revolutionized the management of MS: interferon (IFN) preparations, monoclonal antibodies-natalizumab and ocrelizumab, immunomodulatory agents-glatiramer acetate, sphingosine 1-phosphate receptor 1 (S1PR1) modulators (Siponimod) and teriflunomide. The traditional parenteral drugs are now available as oral formulations improving patient acceptability. Repurposing various agents used for related diseases may reinforce the drug reserve to manage MS and are under trials. Although at a nascent phase, strategies to enhance re-myelination by stimulating oligodendrocytes are fascinating and hold promise for better outcomes in patients with MS. CONCLUSIONS The recent past has seen staggering inclusions to the management of multiple sclerosis catalyzing a significant turnabout in our approach to diagnosis, treatment, and prognosis. Since the advent of DMTs various other oral and injectable agents have been approved. The advances in MS therapeutics and diagnostics have laid the ground for further research and development to enhance the quality of life of afflicted patients.

Abstract
BACKGROUND The decision of initiating treatment for multiple sclerosis (MS) with a high-efficacy DMT (HE DMT) or non-high-efficacy DMT (non-HE DMT) is influenced by several factors, including risk perception of patients and physicians. OBJECTIVE Investigate the influence of physicians' risk perception on decision-making when switching treatments for MS and the reasons for switching. METHODS Data were drawn from the Adelphi Real-World MS Disease-Specific Program (a retrospective survey) and analysis included people with RMS identified between 2017- 2021. RESULTS Of 4129 patients with reasons for switch available, 3538 switched from non-HE DMT and 591 from HE DMT. Overall, 4.7% of patients were switched treatment by their physicians due to the risk of malignancies and infections including PML risk. The proportion of switches that were made due to the risk of PML were 23.9% in the HE DMT and 0.5% in the non-HE DMT groups. The top reasons for switching were relapse frequency (non-HE DMT vs HE-DMT: 26.8% vs 15.2%), lack of efficacy (20.9 vs 11.7) and increased number of MRI lesions (20.3% vs 12.4%). CONCLUSIONS Physicians' risk perception of malignancies and infection excluding PML was not a leading factor when switching treatment. The risk of PML was a key factor, especially for switching patients from HE DMTs. In both groups, lack of efficacy was the key contributing factor for switching. Initiating the treatment with HE DMTs may potentially reduce the number of switches due to sub-optimal efficacy. These findings might help physicians to engage more in discussions with patients about the benefit/risk profile of DMTs.

Abstract
BACKGROUND People with MS (PwMS) and related conditions treated with anti-CD20 and S1P modulating therapies exhibit attenuated immune responses to SARS-CoV-2 vaccines. It remains unclear whether humoral/T-cell responses are valid surrogates for postvaccine immunity. OBJECTIVE To characterize COVID-19 vaccine-breakthrough infections in this population. METHODS We conducted a prospective multicenter cohort study of PwMS and related CNS autoimmune conditions with confirmed breakthrough infections. Postvaccination antibody response, disease-modifying therapies (DMTs) at the time of vaccination, and DMT at the time of infection were assessed. RESULTS Two hundred nine patients had 211 breakthrough infections. Use of anti-CD20 agents at time of infection was associated with increased infection severity (p = 0.0474, odds ratio (OR) = 5.923) for infections during the Omicron surge and demonstrated a trend among the total cohort (p = 0.0533). However, neither use of anti-CD20 agents at the time of vaccination nor postvaccination antibody response was associated with hospitalization risk. Anti-CD20 therapies were relatively overrepresented compared to a similar prevaccination-era COVID-19 cohort. CONCLUSION Use of anti-CD20 therapies during vaccine breakthrough COVID-19 infection is associated with higher severity. However, the attenuated postvaccination humoral response associated with anti-CD20 therapy use during vaccination may not drive increased infection severity. Further studies are necessary to determine if this attenuated vaccine response may be associated with an increased likelihood of breakthrough infection.

Abstract
BACKGROUND Multiple sclerosis (MS) prevalence is rising in the Middle East. Most MS medications are available in the region, but not all, possibly affecting neurologists' prescribing habits. OBJECTIVES To provide an overview of the current practices of Near East (NE) healthcare practitioners by probing their prescribing decisions, to report the COVID-19 impacts on neurologists' prescribing habits, and to explore the future relevance of current medication used in MS management among other newcomers. METHODS A cross-sectional study was carried out using an online survey from April 27, 2022, to July 5, 2022. The questionnaire was designed with the input of five neurologists representing five NE countries (Iran, Iraq, Lebanon, Jordan & Palestine). They identified several factors that play a crucial role in the optimal care of MS patients. The link was shared among neurologists using snowball sampling. RESULTS The survey included 98 neurologists. Effectiveness and safety balance was the most important factor considered when selecting the MS treatment. Among patients with MS, the most challenging factor for the patients was thought to be related to family planning, followed by affordability and tolerability of side effects. In the treatment of mild to moderate relapsing remitting multiple sclerosis (RRMS) in men, Interferon beta 1a SC, Fingolimod, and Glatiramer acetate were the most commonly recommended treatments. Dimethyl fumarate substituted fingolimod in female patients. Interferon beta 1a SC was the safest treatment for mild to moderate RRMS. Interferon beta 1a SC was preferred over other treatments for patients with mild to moderate MS and planning for pregnancy (56.6%) or breastfeeding (60.2%). Fingolimod was not a choice for these patients. Neurologists seemed to discuss the top three treatments of Natalizumab, Ocrelizumab, and Cladribine with patients with highly active MS. When asked to position future disease-modifying therapies five years from today, more than 45% of physicians expressed a lack of information on Bruton's tyrosine kinase (BTK) inhibitors. CONCLUSIONS Most neurologists in the NE region followed Middle East North Africa Committee for Treatment and Research in Multiple Sclerosis (MENACTRIMS) recommendations for prescribing treatment. The treatment choice also depended on the availability of disease-modifying therapies (DMTs) in the region. Regarding the use of upcoming DMTs, there is a clear need for real-world data, long-term extension studies, and comparative studies to support their efficacy and safety profiles in treating patients with MS.

Abstract
BACKGROUND Although the relapse risk is increased after birth in women with relapsing multiple sclerosis (RMS), only a very few disease-modifying therapies (DMTs) are approved during breastfeeding. Glatiramer acetate (GA, Copaxone®) is one of three DMTs that can be used in breastfeeding. The real-world safety of Copaxone® in Offsprings of Breastfeeding and treated RMS pAtients (COBRA) study demonstrated that offspring parameters (hospitalisations, antibiotic use, developmental delays, growth parameters) were similar between offspring breastfed by mothers taking GA or no DMT (control) during breastfeeding. COBRA data analyses were extended to provide further safety data on the impact of maternal GA treatment during breastfeeding on offspring. METHODS COBRA was a non-interventional, retrospective study using German Multiple Sclerosis and Pregnancy Registry data. Participants had RMS, gave birth and had GA or no DMT during breastfeeding. Offspring total adverse events (AEs), non-serious AEs (NAEs) and serious AEs (SAEs) up to 18 months postpartum were assessed. Reasons for offspring hospitalisations and antibiotic treatments were explored. RESULTS Baseline maternal demographics and disease characteristics were similar between cohorts. Each cohort had 60 offspring. Numbers of offspring AEs were comparable between cohorts; total AEs: 82 (GA) vs 83 (control); NAEs: 59 vs 61; SAEs: 23 vs 22. AEs in both cohorts were diverse with no specific patterns. Duration of GA-exposed breastfeeding was 6 to >574 days for offspring with any AE. For all-cause hospitalisations, 11 offspring had 12 hospitalisations (GA cohort) and 12 control offspring had 16 hospitalisations. Most common reason for hospitalisation was infection: 5/12 (41.7%; GA) vs 4/16 (25.0%, control). Two out of 12 (16.7%) hospitalisations due to infection occurred during GA-exposed breastfeeding; the others occurred 70, 192 and 257 days after discontinuation of GA-exposed breastfeeding. Median (range) duration of GA-exposed breastfeeding was 110 (56 to ≥285) days for offspring hospitalised for infections and 137 (88-396) days for those hospitalised for other reasons. Nine offspring had 13 antibiotic treatments (GA cohort) and nine control offspring had 10 treatments. Ten out of 13 (76.9%) antibiotic treatments occurred during GA-exposed breastfeeding, of which four were primarily due to double kidney with reflux. Other antibiotic treatments occurred 193, 229 and 257 days after discontinuation of GA-exposed breastfeeding. CONCLUSIONS GA treatment of mothers with RMS during breastfeeding did not increase AEs, hospitalisations or antibiotic use in their offspring versus control offspring. These data support previous COBRA data that the benefit of maternal RMS treatment with GA during breastfeeding outweighs the potential, apparently low risk of untoward events, in their breastfed offspring.

Abstract
OBJECTIVE Disease-modifying therapies (DMTs) in multiple sclerosis (MS) may affect the course and outcome of COVID-19, but withholding them could permit disease activity. This study aimed to understand the course of COVID-19 in unvaccinated patients with MS on disease-modifying therapies. SUBJECTS AND METHODS This descriptive study examined the course of COVID-19 among infected patients with MS followed up at a large tertiary center in Kuwait between March 1, 2020, and March 1, 2021. All subjects were outpatients at the time of data collection. RESULTS We studied 51 patients with MS confirmed to be infected with SARS-CoV-2 using real-time polymerase chain reaction. Of these patients, 33/51 were female, median age was 35 years (IQR 27-39 years), median Expanded Disability Status Scale score was 1.5 (IQR zero-3), and 47/51 had RRMS. B-cell-depleting agents (ocrelizumab and rituximab) were given to 19 patients, another 19 were on immune cell traffickers (fingolimod and natalizumab), and 13 were on other DMT treatments (alemtuzumab, cladribine, interferon-beta, dimethyl fumarate, and teriflunomide). 43/51 of these patients experienced mild COVID-19, not requiring hospitalization. None of the subjects experienced MS relapses during infection. Two patients on rituximab had a moderate course of the illness, which required hospitalization for oxygen support, but did not need mechanical ventilation; the rest of the subjects remained asymptomatic. CONCLUSIONS These findings suggest that DMT may not adversely affect the course of COVID-19 in MS patients; however, patients on B-cell-depleting agents trended toward a worse outcome.

Abstract
BACKGROUND There is a paucity of information on maternal multiple sclerosis (MS) and risk of adverse pregnancy and perinatal outcomes. OBJECTIVE The aim of this study was to determine the association between MS and risks of adverse pregnancy and perinatal outcomes in women with MS. In women with MS, the influence of exposure to disease-modifying therapy (DMT) was also investigated. METHODS Population-based retrospective cohort study on singleton births to mothers with MS and matched MS-free mothers from the general population in Sweden between 2006 and 2020. Women with MS were identified through Swedish health care registries, with MS onset before child's birth. RESULTS Of 29,568 births included, 3418 births were to 2310 mothers with MS. Compared with MS-free controls, maternal MS was associated with increased risks of elective caesarean sections, instrumental delivery, maternal infection and antepartum haemorrhage/ placental abruption. Compared with offspring of MS-free women, neonates of mothers with MS were at increased risks of medically indicated preterm birth and being born small for gestational age. DMT exposure was not associated with increased risks of malformations. CONCLUSIONS While maternal MS was associated with a small increased risk of few adverse pregnancy and neonatal outcomes, DMT exposure close to pregnancy was not associated with major adverse outcomes.

Abstract
INTRODUCTION This study assessed the cost-effectiveness of ozanimod compared with commonly used disease-modifying therapies (DMTs) for relapsing-remitting multiple sclerosis (RRMS). METHODS Annualized relapse rate (ARR) and safety data were obtained from a network meta-analysis (NMA) of clinical trials of RRMS treatments including ozanimod, fingolimod, dimethyl fumarate, teriflunomide, interferon beta-1a, interferon beta-1b, and glatiramer acetate. ARR-related number needed to treat (NNT) relative to placebo and annual total MS-related healthcare costs was used to estimate the incremental annual cost per relapse avoided with ozanimod vs each DMT. ARR and adverse event (AE) data were combined with drug costs and healthcare costs to manage relapses and AEs in order to estimate annual cost savings with ozanimod vs other DMTs, assuming a 1 million USD fixed treatment budget. RESULTS Treatment with ozanimod was associated with lower incremental annual healthcare costs to avoid a relapse, ranging from $843,684 vs interferon beta-1a (30 μg; 95% confidence interval [CI] - $1,431,619, - $255,749) to $72,847 (95% CI - $153,444, $7750) vs fingolimod. Compared with all other DMTs, ozanimod was associated with overall healthcare cost savings ranging from $8257 vs interferon beta-1a (30 μg) to $2178 vs fingolimod. Compared with oral DMTs, ozanimod was associated with annual cost savings of $6199 with teriflunomide 7 mg, $4737 with teriflunomide 14 mg, $2178 with fingolimod, and $2793 with dimethyl fumarate. CONCLUSION Treatment with ozanimod was associated with substantial reductions in annual drug costs and total MS-related healthcare costs to avoid relapses compared with other DMTs. In the fixed-budget analysis, ozanimod demonstrated a favorable cost-effective profile relative to other DMTs.

Abstract
INTRODUCTION The current therapeutic landscape of Alzheimer's disease (AD) is evolving rapidly. Our treatment options include new anti-amyloid-β protein disease-modifying therapies (DMTs) that decrease cognitive decline in patients with early AD (prodromal and mild AD dementia). Despite these advances, we have limited information on how neurologists would apply the results of recent DMT trials to make treatment decisions. Our goal is to identify factors associated with the use of new AD DMTs among neurologists applying concepts from behavioral economics. METHODS This non-interventional, cross-sectional, web-based study will assess 400 neurologists with expertise in AD from across Spain. Participants will start by completing demographic information, practice settings, and a behavioral battery to address their tolerance to uncertainty and risk preferences. Participants will then be presented with 10 simulated case scenarios or vignettes of common encounters in patients with early AD to evaluate treatment initiation with anti-amyloid-β DMTs (e.g., aducanumab, lecanemab, etc.). The primary outcomes will be therapeutic inertia and suboptimal decisions. Discrete choice experiments will be used to determine the weight of factors influencing treatment choices. RESULTS The results of this study will provide new insights into a better understanding of the most relevant factors associated with therapeutic decisions on the use of DMTs, assessing how neurologists handle uncertainty when making treatment choices, and identifying the prevalence of therapeutic inertia in the management of early AD.

Abstract
No disease-modifying therapies are currently available for Alzheimer's disease (AD) in Europe. Current evidence from clinical trials testing anti-beta amyloid (Aβ) monoclonal antibodies (mAbs) in patients with early AD, though, suggests a likely marketing authorization in the next years. Since the implementation of disease-modifying therapies for AD in the clinical practice will evidently require a huge change of dementia care in all countries, a group of prominent AD clinical experts in Italy met to discuss patients' selection and management strategies. The current diagnostic-therapeutic standard of care in Italy was taken as the starting point. The prescription of new therapies cannot ignore the definition of a biological diagnosis through the assessment of both amyloid- and tau-related biomarkers. The high risk/benefit ratio of anti-Aβ immunotherapies, moreover, needs a highly specialized diagnostic work-up and a thorough exclusion criteria assessment, which should be provided by a neurology specialist. The Expert Panel also suggests a reorganization of the Centers for dementia and cognitive decline in Italy into 3 levels of increasing complexity: community center, first- and second-level center. Tasks and requirements for each level were defined. Finally, specific characteristics of a center deputed to prescribe anti-Aβ mAbs were discussed.

Abstract
Background We aimed to determine the proportion of highly active multiple sclerosis patients under high-efficacy therapies (HETs) achieve no evidence of disease activity-3 (NEDA-3) at 1 and 2 years, and to identify factors associated with failing to meet no evidence of disease activity 3 at 2 years. Methods This retrospective cohort study based on Argentina Multiple Sclerosis patient registry (RelevarEM), includes highly active multiple sclerosis patients who received HETs. Results In total, 254 (78.51%) achieved NEDA-3 at year 1 and 220 (68.12%) achieved NEDA-3 at year 2. Patients who achieved NEDA-3 at 2 years had a shorter duration of multiple sclerosis (p < 0.01) and a shorter time between first treatment and current treatment (p = 0.01). Early high-efficacy strategy patients reached NEDA-3 more frequently (p < 0.01). Being a naïve patient (odds ratio: 3.78, 95% confidence interval 1.50-9.86, p < 0.01) was an independent predictor to reach NEDA-3 at 2 years. No association was found between type of HETs and NEDA-3 at 2 years when adjusted for potential confounders (odds ratio: 1.73; 95% confidence interval 0.51-6.06, p 0.57). Conclusion We found a high proportion of patients who achieved NEDA-3 at 1 and 2 years. Early high-efficacy strategy patients had a higher probability of achieving NEDA-3 at 2 years.

Abstract
INTRODUCTION The discontinuation of disease-modifying therapies (DMTs) in multiple sclerosis (MS) is commonly seen in real-world settings due to several factors. AREA COVER The aim of this study is to describe the frequency of disease activity after discontinuation of DMTs in MS patients included in the Argentinean MS and NMOSD registry. DISCUSION Patients with relapsing remitting MS (RRMS) and active secondary progressive MS (SPMS) were included based on the following criteria: they discontinued treatment for more than 6 months, they had been treated with a DMT for ≥2 years, and they had at least 6 months of follow-up in the registry after discontinuation. Demographic and clinical data were collected. Disease activity during follow-up was defined as the presence of a clinical relapse or a new magnetic resonance (MRI) lesion (either new lesions on T2-weighted sequence and/or contrast enhancement). Bivariate analysis was applied to identify clinical and demographic factors related to disease activity. CONCLUSION We included 377 patients (75.5% RRMS, 22.5% SPMS) who had discontinued DMTs. The mean (SD) follow-up after discontinuation was 15.7 (7.9) months. After discontinuation, the presence of relapse was detected in 18.8% and 3.5% in RRMS and SPMS, respectively; and new MRI activity in 22% and 3.5%, respectively. We found that higher risk of relapse and MRI activity was associated with younger age (p < 0.001), shorter disease duration (p < 0.001), and RRMS phenotype (p = 0.006). Males showed higher MRI activity (p 0.011). This study provides real-world data that can guide physicians when considering discontinuation of DMTs.

Abstract
Background Multiple sclerosis (MS) is often diagnosed in women of childbearing age (WCBA), with a mean age of onset of 30 years. Women with MS have long been cautioned to carefully plan their pregnancies and, traditionally, disease-modifying therapies (DMTs) have not been recommended for use in patients engaged in family planning. In 2020, the United States Food and Drug Administration (FDA) approved a label update for interferon beta (IFN ß) by adding new safety data on pregnancy and breastfeeding. Because current management guidelines do not yet reflect the recent label update, a panel of neurology experts from Iraq decided to discuss the potential need for changes in treatment strategies in Iraq. Methods A panel of experts consisting of 8 neurologists from Iraq and one international neurology expert from Germany convened to develop an expert opinion that would provide practical guidance for the pharmacological management of WCBA with MS in Iraq. They considered the latest label update and relevant published literature, along with local clinical practice and available resources. Results Interferon and Glatiramer acetate have no evidence of harm during pregnancy. IFN β can be continued safely through pregnancy. Switching treatment during pregnancy is generally not recommended. Short-term intravenous methylprednisolone can be used to treat disabling relapses. Conclusion Given the complexity of managing MS in pregnant women, it is the opinion of the expert panel that family planning should be discussed early in the disease course, planned pregnancy should be encouraged, and open communication with patient for her treatment decisions is paramount. Patients who are engaged in family planning are no longer discouraged from treatment with some of the currently available DMTs.

Abstract
BACKGROUND Immunogenicity data shows blunted responses to COVID-19 vaccination among people with MS (pwMS) on certain disease-modifying therapies (DMTs). Still, it is uncertain how this data translates into the clinic. OBJECTIVE To assess the effect of DMTs and other factors on the effectiveness of inactivated vaccination in pwMS. METHODS This cohort study was conducted in a period in which Iran experienced two COVID-19 peaks caused by the Delta variant. We used multivariable cox regression to compare COVID-19-free survivals, and an ordinal logistic model to compare COVID-19 severity between vaccinated pwMS on different DMTs. RESULTS A total of 617 pwMS were included in the final analysis, with a mean [SD] follow-up of 25.59 weeks [5.48] after their second dose. Laboratory/imaging-confirmed breakthrough COVID-19 occurred in 15/277 (5.41%) of injectable-treated (reference), 10/61 (16.39%) of fingolimod-treated (adjusted hazard ratio (aHR) [95% confidence interval (CI)]: 2.80 [1.24, 6.29]; P = 0.01), 9/128 (7.03%) of other oral-treated (aHR [95%CI]: 1.16 [0.50, 2.68]; P = 0.73), 19/145 (13.10%) of anti-CD20-treated (aHR [95%CI]: 2.11 [1.05, 4.22]; P = 0.04), and 6/56 (10.71%) of non-treated pwMS (aHR [95%CI]: 1.52 [0.57, 4.04]; P = 0.40). Age (adjusted Odds Ratio [aOR] [95%CI]: 1.05 [1.00, 1.10], P = 0.05) number of comorbidities (aOR [95%CI]: 2.05 [1.06, 3.96], P = 0.03), fingolimod therapy (aOR [95%CI]: 10.39 [2.47, 43.62], P < 0.01), and anti-CD20 therapy (aOR [95%CI]: 4.44 [1.49, 13.23], P < 0.01) were independently associated with a more severe COVID-19 course. CONCLUSION The observed results stress the importance of developing personalized vaccination schedules and reservation of COVID-19 treatment resources for older pwMS with comorbidities receiving fingolimod or anti-CD20 therapies.

Abstract
Multiple sclerosis (MS) is characterized by a complex etiology that is mirrored by the perplexing and inconsistent treatment responses observed across different patients. Although epigenetic research has garnered rightful interest in its efforts towards demystifying and understanding aberrant responses to treatment, the interim undoubtedly requires alternative non-pharmacological approaches towards attaining more effective management strategies. Of particular interest in this review is resistance training (RT) as a non-pharmacological exercise-based interventional strategy and its potential role as a disease-modifying tool. RT has been reported across literature to positively influence numerous aspects in the quality of life (QoL) and functional capacity of MS patients, and one of the attributes of these benefits may be a shift in the immune system of these individuals. RT has also been proven to affect different immune system key players associated with MS pathology. Ultimately, this brief review aims to provide a potential yet crucial link between RT, alterations in the expression profile of the immune system, and finally an imminent improvement in the overall well-being and QoL of MS patients, suggesting that utilizing RT as an interventional exercise modality may be an effective strategy that would aid in managing such a complex and debilitating disease.

Abstract
BACKGROUND Patients with relapsing-remitting multiple sclerosis commonly switch between disease-modifying therapies (DMTs). Identifying predictors of relapse when switching could improve outcomes. OBJECTIVE To determine predictors of relapse hazard when switching to cladribine. METHODS Data of patients who switched to cladribine, grouped by prior disease-modifying therapy (pDMT; interferon-β/glatiramer acetate, dimethyl fumarate, teriflunomide, fingolimod or natalizumab (NTZ)), were extracted from the MSBase Registry. Predictors of relapse hazard during the treatment gap and the first year of cladribine therapy were determined. RESULTS Of 513 patients, 22 relapsed during the treatment gap, and 38 within 1 year of starting cladribine. Relapse in the year before pDMT cessation predicted treatment gap relapse hazard (hazard ratio (HR) = 2.43, 95% confidence interval (CI) = 1.03-5.71). After multivariable adjustment, relapse hazard on cladribine was predicted by relapse before pDMT cessation (HR = 2.00, 95% CI = 1.01-4.02), treatment gap relapse (HR = 6.18, 95% confidence interval (CI) = 2.65-14.41), switch from NTZ (HR compared to injectable therapies 4.08, 95% CI = 1.35-12.33) and age at cladribine start (HR = 0.96, 95% CI = 0.91-0.99). CONCLUSION Relapse during or prior to the treatment gap, and younger age, are of prognostic relevance in the year after switching to cladribine. Switching from NTZ is also independently associated with greater relapse hazard.

Abstract
INTRODUCTION Several disease-modifying therapies (DMTs) show efficacy in relapsing-remitting multiple sclerosis (RRMS) and clinically isolated syndrome (CIS). However, there is still a relevant proportion of patients who remain untreated. We provide real-world data on untreated and treated patients and we report whether and how the introduction of oral DMTs changed the treatment decision. Furthermore, we discuss possible reasons for not receiving DMTs. METHODS We conducted a retrospective cross-sectional study and analysed demographic and clinical data of patients with RRMS and CIS at our MS center. Comparison was made between untreated and treated patients in 2010 (before the introduction of oral DMTs) and in 2014 (after the introduction of oral DMTs). Furthermore, we analysed reasons for the decision against DMTs in patients who never received DMTs and patients who discontinued DMTs. RESULTS We analysed datasets of 344 MS patients in 2010 and 253 in 2014. There were more untreated patients in CIS than in RRMS. In RRMS, the proportion of untreated patients decreased significantly between 2010 and 2014 from 23.6% to 11.1%, while the use of oral medications increased significantly from <1% to more than 50% in 2014. In CIS, there was no significant change in untreated patients between 2010 and 2014 (61.1% in 2010 to 52.6% in 2014). Untreated patients with RRMS were significantly older and had lower ARR than treated patients. Patients who never received DMT had lower EDSS compared to patients that had been treated before. The main reasons for the decision against DMT were "belief in a benign course" and "fear of adverse effects". Treatment discontinuation was caused mainly by the adverse effects. DISCUSSION In our data a relevant proportion of patients with RRMS and CIS did not receive any DMT. We hypothesize that in patients with RRMS the introduction of oral DMTs translated to a higher rate of treatment, whereas in CIS there no change was observed. This could be due to limited therapeutic options in CIS. There is more information needed regarding the treatment recommendation for older patients and patients with mild course of the disease.

Abstract
BACKGROUND Following the outbreak of COVID-19, global healthcare systems have had to rapidly adapt. People with multiple sclerosis (pwMS) were required to make decisions about their individual risk and consequent work and social behaviors. This study aimed to evaluate risk perception and patterns of shielding behavior amongst pwMS at the onset of the COVID-19 pandemic and the subsequent impact on patients' employment and access to disease modifying therapies (DMTs). METHODS Postal surveys were sent to 1690 people within a UK population-based MS cohort during the first wave of the COVID-19 pandemic. Patients were surveyed on: (i) perceived vulnerability to COVID-19; (ii) isolation behavior; (iii) interruption to DMT; (iv) employment status; (v) level of satisfaction with their current working arrangement. RESULTS Responses were received from 1000 pwMS. Two thirds of patients reported isolating at home during the first wave of the pandemic. This behavior was associated with increased age (p<0.0001), higher disability (p<0.0001) and use of high-efficacy DMTs (p = 0.02). The majority of patients reported feeling vulnerable (82%) with perceived vulnerability associated with higher EDSS (p<0.0001) and receiving a high-efficacy DMT (p = 0.04). Clinician-defined risk was associated with shielding behavior, with those at high-risk more likely to self-isolate/shield (p<0.0001). Patients on high-efficacy DMTs were more likely to have an interruption to their treatment (50%) during the first wave of the pandemic. Most pwMS experienced a change to their working environment, and most were satisfied with the adjustments. CONCLUSION This study highlights the risk perception, social behavioral practices and changes to treatment experienced by pwMS during the first wave of the COVID-19 pandemic in a large, well-described UK cohort. The results may help inform management of pwMS during future pandemic waves.

Abstract
The SARS-COV-2 pandemic has been a global public health problem since 2019, with over 400 million reported cases, 6 million deaths, and significant economic and social damage. Overlapping SARS-CoV-2 infection in patients with chronic diseases, such as multiple sclerosis (MS), causes management problems, especially in patients treated with disease-modifying therapies. Studies investigating COVID-19 vaccination effectiveness have shown variability in postvaccination immune response that depends on the patient's background treatment, and special attention is required for anti-CD20 therapies. Existing data on the efficacy of COVID-19 vaccination in patients with MS undergoing disease-modifying treatment are summarized and critically evaluated in this article.

Abstract
The SARS-CoV-2 pandemic has raised particular concern for people with Multiple Sclerosis, as these people are believed to be at increased risk of infection, especially those being treated with disease-modifying therapies. Therefore, the objective of this review was to describe how COVID-19 affects people who suffer from Multiple Sclerosis, evaluating the risk they have of suffering an infection by this virus, according to the therapy to which they are subjected as well as the immune response of these patients both to infection and vaccines and the neurological consequences that the virus can have in the long term. The results regarding the increased risk of infection due to treatment are contradictory. B-cell depletion therapies may cause patients to have a lower probability of generating a detectable neutralizing antibody titer. However, more studies are needed to help understand how this virus works, paying special attention to long COVID and the neurological symptoms that it causes.

Abstract
Introduction The mechanisms of action of disease-modifying therapies (DMTs) for multiple sclerosis (MS) are complex and involve an interplay of immune system components. People with MS (PwMS) may lack a clear understanding of the immunological pathways involved in MS and its treatment; effective communication between healthcare professionals (HCPs) and PwMS is needed to facilitate shared decision-making when discussing the disease and selecting DMTs and is particularly important in the coronavirus disease 2019 (COVID-19) era. Methods In this patient-authored two-part review, we performed a targeted literature search to assess the need for better communication between HCPs and PwMS regarding treatment selection, and also conducted a qualitative survey of four patient and care-partner authors to obtain insights regarding their understanding of and preferences for the treatment and management of MS. Results Following a search of the Embase and MEDLINE databases using Ovid in June 2020, an analysis of 40 journal articles and conference abstracts relating to patient empowerment and decision-making in DMT selection for MS showed a preference for safety and efficacy of treatments, followed by autonomy and convenience of administration. A need for better communication between HCPs and PwMS during treatment selection to improve patient satisfaction was also identified. The open survey responses from the patient authors revealed a need for greater involvement in decision-making processes and desire for improved communication and information tools. Conclusions This targeted literature search and phenomenological review confirms PwMS preferences for empowered decision-making in disease management and treatment selection, to optimize independence, safety, and efficacy. It also identifies an unmet need for improved communication and information tools that convey MS information in a relatable manner. Furthermore, this review seeks to address this unmet need by providing plain language figures and descriptions of MS immune mechanisms that can be used to facilitate discussions between HCPs and PwMS. Supplementary Information The online version contains supplementary material available at 10.1007/s40120-022-00349-5. In multiple sclerosis (MS), there are different cells in the immune system that contribute to the disease. The main cells in the immune system are T and B cells. People with MS (PwMS) might not be familiar with details about the immune system, and healthcare professionals might not always communicate details about how treatments work clearly to PwMS when choosing treatments with them. It is important for PwMS to have all the information they need to help make decisions about treatments. This information needs to be given in a way they can understand. This is especially important during the coronavirus disease 2019 (COVID-19) pandemic. In this paper, we first looked at what research has already been published about what is most important to PwMS when making treatment decisions. The existing research says that safety and effectiveness are the most important things and that PwMS prefer treatments that they can take themselves. PwMS also need better communication and information from doctors to make decisions and to help explain how MS treatments work in the body. Next, we gave a survey to the patients who are authors of this paper to ask about what is important to them when making treatment decisions. Their answers were very similar to the existing research. Overall, PwMS need better communication from healthcare professionals about the immune system. This paper also includes plain language descriptions and figures to help healthcare professionals explain and discuss the importance of the immune system in MS with PwMS.

Abstract
INTRODUCTION The recent advent of disease-modifying therapies (DMTs) has dramatically changed the treatment landscape of spinal muscular atrophy (SMA), and the multifaceted impact of this advancement has not been assessed thoroughly in the growing body of literature. We sought to summarize the literature on the natural history of SMA and the impact of SMA DMTs, including health-related quality of life (HRQOL) and utilities, clinical efficacy and safety, and economic impact. METHODS Systematic literature reviews were conducted following PRISMA guidelines with no inclusive dates. Relevant studies were identified by searching full-text databases on November 12-13, 2020, including MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials, and EconLit, conference proceedings, health technology assessment databases, and clinical trial registries. All searches used a combination of MeSH and key terms. Studies were screened according to criteria based upon population, intervention, outcomes, and study design structure. RESULTS Findings from 17, 23, 32, and 42 studies were included for the evaluation of natural history of SMA, HRQOL and utilities, clinical efficacy and safety, and economic impact of DMTs, respectively. Currently available data indicate that untreated SMA is associated with considerable humanistic and economic burden, with estimates of costs varying by treatment. While a variety of interventions have been evaluated in SMA clinical trials, quantitative synthesis of safety and efficacy findings was not feasible because of inconsistencies in reported outcomes. Data assessing impacts of DMTs on HRQOL were also lacking. CONCLUSIONS Overall, this systematic literature review highlights a clear need for up-to-date and methodologically rigorous clinical, HRQOL, and economic data to support unbiased assessments of the relative clinical and economic effectiveness of SMA treatments. More research is required to extend our understanding of the burden of SMA on HRQOL utility assessments and the impact of new DMTs on HRQOL and utilities for patients with SMA.

Abstract
Monoclonal antibodies (mAbs) against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) received emergency use authorization for the acute treatment of COVID-19. We are not aware of published data on their use in immunosuppressed people with multiple sclerosis (pwMS). We report 23 pwMS (mean age = 49 years, ocrelizumab (n = 19), fingolimod (n = 2), vaccinated with at least an initial series (n = 19)) who received mAb for acute COVID-19. Following mAb receipt, approximately half recovered in <7 days (48%). There were no adverse events or deaths. Use of mAb for pwMS treated with fingolimod or ocrelizumab was not observed to be harmful and is likely helpful for treatment of acute COVID-19.

Abstract
Background Hand dexterity impairment is a key feature of disability in people with primary progressive multiple sclerosis (PPMS). So far, ocrelizumab, a recombinant humanized monoclonal antibody that selectively depletes CD20-expressing B cells, is the only therapy approved for PPMS and recent analysis reported its ability to reduce the risk of upper limb disability progression. However, the neural mechanisms underlying hand impairment in PPMS and the brain networks behind the effect of ocrelizumab on manual dexterity are not fully understood. Objective Main aims of our study were: (i) to investigate neurophysiological and behavioural correlates of hand function impairment in subjects with PPMS, and (ii) to use neurophysiologic and behavioural measures to track the effects of ocrelizumab therapy on manual dexterity. Methods Seventeen PPMS patients and 17 healthy-controls underwent routine neurophysiological protocols assessing the integrity of cortico-spinal and somatosensory pathways and advanced transcranial magnetic stimulation (TMS) protocols evaluating inhibitory (short and long interval intracortical inhibition, short-latency afferent inhibition) and facilitatory (motor thresholds, intracortical facilitation, short-interval intracortical facilitation) circuits in the primary motor cortex. All subjects also underwent behavioural analysis of hand dexterity by means of nine-hole peg test and finger movement analysis, and hand strength with handgrip and three-point pinch test. Neurophysiological and clinical assessments of hand functionality were also performed after 1 year of ocrelizumab therapy. Results At baseline PPMS patients displayed a significant impairment of hand dexterity and strength compared to healthy controls (all p < 0.03). Neurophysiological study disclosed prolonged latencies of standard somatosensory and motor evoked potentials (all p < 0.025) and an overall reduction of intracortical excitability at TMS protocols, involving both excitatory and inhibitory circuits. Importantly, hand dexterity impairment, indexed by delayed 9HPT, correlated with TMS protocols investigating cortical sensorimotor integration (short-latency afferent inhibition, SAI), p = 0.009. Both parameters, 9HPT (p = 0.01) and SAI (p = 0.01), displayed a significant improvement after 1 year of therapy with ocrelizumab. Conclusion Intracortical sensorimotor networks are involved in hand dexterity dysfunction of PPMS. Ocrelizumab therapy displays a beneficial effect on hand dexterity impairment most likely through intracortical networks implicated in fast sensorimotor integration.

Abstract
Background Few data are available so far on the antibody-mediated immune response to anti-SARS-Cov2 vaccination in people with multiple sclerosis (pwMS) treated with disease-modifying treatments (DMTs), therefore this issue was explored in a real-life cohort of pwMS. Materials and methods Retrospective monocentric study on anti-spike protein antibody response in pwMS who had received vaccination for Sars-Cov2. Adverse events following vaccination were also recorded. Results One hundred and twenty pwMS were included: 83 females (69%); median age at vaccination 42 years (range 21–73); 112/120 patients (93%) were receiving DMTs at vaccination. Anti-spike protein IgG antibodies were detectable in 102/120 (85%) cases overall, being the proportion lower in pwMS receiving anti-CD20 antibodies (14/31, 45%) compared to non-depletive treatments (77/78, 99%), p < 0.0001. Median anti-spike titre was lower in anti-CD20 antibodies and fingolimod-treated pwMS compared to those receiving other DMTs, and it correlated with anti-CD20 treatment duration (R − 0.93, p < 0.0001) and with age at vaccination in pwMS not receiving depletive treatments (R − 0.25, p = 0.028). Baseline CD19+ cell count (where available) was higher in the responder group than in non-responders, p < 0.0001. Two symptomatic COVID-19 infections were diagnosed over a median follow-up of 5 months (range 2–7); adverse events were aligned with the published literature. Conclusion Antibody response to anti-COVID-19 vaccines was detected in most of the pwMS analysed, but frequency of responders was reduced in those receiving CD20 depleting therapies compared to other DMTs-treated pwMS. Investigations on cell-mediated immune response are needed to assess whether a protective immune response is elicited also in non-antibody responders.

Abstract
BACKGROUND Six monthly courses of mitoxantrone were approved in France in 2003 for patients with highly active multiple sclerosis (MS). OBJECTIVE To report the 10-year clinical follow-up and safety of mitoxantrone as an induction drug followed by maintenance therapy in patients with early highly active relapsing-remitting MS (RRMS) and an Expanded Disability Status Scale (EDSS) score<4, 12months prior to mitoxantrone initiation. METHODS In total, 100 consecutive patients with highly active RRMS from the Rennes EDMUS database received monthly mitoxantrone 20mg combined with methylprednisolone 1g for 3 (n=75) or 6months (n=25) followed by first-line disease-modifying drug (DMD). The 10-year clinical impact was studied through clinical activity, DMD exposure, and adverse events. RESULTS Twenty-four percent were relapse-free over 10years and the mean annual number of relapses was 0.2 at 10years. The mean EDSS score remained significantly improved for up to 10years, changing from 3.5 at mitoxantrone initiation to 2.7 at 10years. The probability of disability worsening and improvement from mitoxantrone initiation to 10years were respectively 27% and 58%, and 13% converted to secondary progressive MS. Patients only remained untreated or treated with a first-line maintenance DMD for 6.5years in average. In our cohort, mitoxantrone was generally safe. No leukemia was observed and six patients developed neoplasms, including 4 solid cancers. CONCLUSION Monthly mitoxantrone for 3 or 6months, followed by maintenance first-line treatment, may be an attractive therapeutic option for patients with early highly active RRMS, particularly in low-income countries.
