Abstract
BACKGROUND AND PURPOSE Rituximab (RTX) is frequently used off-label in multiple sclerosis. However, studies on the risk-benefit profile of RTX in pediatric-onset multiple sclerosis are scarce. METHODS In this multicenter retrospective cohort study, patients with pediatric-onset multiple sclerosis from Sweden, Austria and Germany, who received RTX treatment were identified by chart review. Annualized relapse rates, Expanded Disability Status Scale scores and magnetic resonance imaging parameters (new T2 lesions and contrast-enhancing lesions) were assessed before and during RTX treatment. The proportion of patients who remained free from clinical and disease activity (NEDA-3) during RTX treatment was calculated. Side effects such as infusion-related reactions, infections and laboratory abnormalities were assessed. RESULTS Sixty-one patients received RTX during a median (interquartile range) follow-up period of 20.9 (35.6) months. The annualized relapse rate decreased from 0.6 (95% confidence interval [CI] 0.38-0.92) to 0.03 (95% CI 0.02-0.14). The annual rate of new T2 lesions decreased from 1.25 (95% CI 0.70-2.48) to 0.08 (95% CI 0.03-0.25) and annual rates of new contrast-enhancing lesions decreased from 0.86 (95% CI 0.30-3.96) to 0. Overall, 70% of patients displayed no evidence of disease activity (NEDA-3). Adverse events were observed in 67% of patients. Six patients discontinued treatment due to ongoing disease activity or adverse events. CONCLUSION Our study provides class IV evidence that RTX reduces clinical and radiological activity in pediatric-onset multiple sclerosis.

Abstract
Pediatric onset multiple sclerosis (POMS) in the very young is a very rare entity and presents a difficult diagnostic challenge due to overlapping signs and symptoms with other diseases. We present a 4-year-old boy who initially presented with right-sided hemiparesis and demyelinating lesions on MRI. Follow-up MRI examinations 3 and 6 months later revealed new demyelinating lesions. Ten months after initial presentation, he presented with right-sided hemiparesis, central facial nerve palsy on the right side and new demyelinating lesions on MRI. Two clinical events and new MRI lesions on follow-up MRIs confirmed the diagnosis of POMS. He was treated with rituximab and experienced no further relapses or radiological progression during the follow-up period.

Abstract
Importance Moderately effective therapies (METs) have been the main treatment in pediatric-onset multiple sclerosis (POMS) for years. Despite the expanding use of highly effective therapies (HETs), treatment strategies for POMS still lack consensus. Objective To assess the real-world association of HET as an index treatment compared with MET with disease activity. Design, Setting, and Participants This was a retrospective cohort study conducted from January 1, 2010, to December 8, 2022, until the last recorded visit. The median follow-up was 5.8 years. A total of 36 French MS centers participated in the Observatoire Français de la Sclérose en Plaques (OFSEP) cohort. Of the total participants in OFSEP, only treatment-naive children with relapsing-remitting POMS who received a first HET or MET before adulthood and at least 1 follow-up clinical visit were included in the study. All eligible participants were included in the study, and none declined to participate. Exposure HET or MET at treatment initiation. Main Outcomes and Measures The primary outcome was the time to first relapse after treatment. Secondary outcomes were annualized relapse rate (ARR), magnetic resonance imaging (MRI) activity, time to Expanded Disability Status Scale (EDSS) progression, tertiary education attainment, and treatment safety/tolerability. An adapted statistical method was used to model the logarithm of event rate by penalized splines of time, allowing adjustment for effects of covariates that is sensitive to nonlinearity and interactions. Results Of the 3841 children (5.2% of 74 367 total participants in OFSEP), 530 patients (mean [SD] age, 16.0 [1.8] years; 364 female [68.7%]) were included in the study. In study patients, both treatment strategies were associated with a reduced risk of first relapse within the first 2 years. HET dampened disease activity with a 54% reduction in first relapse risk (adjusted hazard ratio [HR], 0.46; 95% CI, 0.31-0.67; P < .001) sustained over 5 years, confirmed on MRI activity (adjusted odds ratio [OR], 0.34; 95% CI, 0.18-0.66; P = .001), and with a better tolerability pattern than MET. The risk of discontinuation at 2 years was 6 times higher with MET (HR, 5.97; 95% CI, 2.92-12.20). The primary reasons for treatment discontinuation were lack of efficacy and intolerance. Index treatment was not associated with EDSS progression or tertiary education attainment (adjusted OR, 0.51; 95% CI, 0.24-1.10; P = .09). Conclusions and Relevance Results of this cohort study suggest that compared with MET, initial HET in POMS was associated with a reduction in the risk of first relapse with an optimal outcome within the first 2 years and was associated with a lower rate of treatment switching and a better midterm tolerance in children. These findings suggest prioritizing initial HET in POMS, although long-term safety studies are needed.

Abstract
PURPOSE OF REVIEW Multiple sclerosis is a chronic inflammatory disease of the central nervous system. When seen in children and adolescents, crucial stages of brain development and maturation may be affected. Prompt recognition of multiple sclerosis in this population is essential, as early intervention with disease-modifying therapies may change developmental trajectories associated with the disease. In this paper, we will review diagnostic criteria for pediatric multiple sclerosis, outcomes, differential diagnosis, and current therapeutic approaches. RECENT FINDINGS Recent studies have demonstrated the utility of newer structural and functional metrics in facilitating early recognition and diagnosis of pediatric MS. Knowledge about disease-modifying therapies in pediatric multiple sclerosis has expanded in recent years: important developmental impacts of earlier therapeutic intervention and use of highly effective therapies have been demonstrated. Pediatric MS is characterized by highly active disease and high disease burden. Advances in knowledge have led to early identification, diagnosis, and treatment. Lifestyle-related interventions and higher efficacy therapies are currently undergoing investigation.

Abstract
AIM To compare the efficacy and safety of newer and/or second-line disease-modifying treatments (DMTs) with interferon beta-1a. METHOD This observational retrospective study included patients younger than 18 years old in the French KIDBIOSEP cohort who had a diagnosis of relapsing multiple sclerosis between 2008 and 2019 and received at least one DMT. Primary outcome was the annualized relapse rate (ARR). Secondary outcomes were the risk of new T2 or gadolinium-enhanced lesions on brain MRI. RESULTS Among 78 patients enrolled, 50 were exposed to interferon and 76 to newer DMTs. Mean ARR went from 1.65 during pre-treatment period to 0.45 with interferon (p < 0.001). Newer DMTs reduced ARR compared to interferon: fingolimod 0.27 (p = 0.013), teriflunomide 0.25 (p = 0.225), dimethyl-fumarate 0.14 (p = 0.045), natalizumab 0.03 (p = 0.007). Risk of new lesions on MRI was reduced with interferon compared to pre-treatment period; it decreased even more with newer DMTs for T2 lesions. Regarding risk of new gadolinium-enhanced lesions, the added value of new treatments compared to interferon was less obvious, except for natalizumab (p = 0.031). CONCLUSION In this real-world setting, newer DMTs showed better efficacy than interferon beta-1a on ARR and risk of new T2 lesions, with a good safety profile. Natalizumab tend to emerge as the most effective treatment.

Abstract
BACKGROUND Treatment of pediatric-onset multiple sclerosis (POMS) is challenging given the lack of safety and efficacy data in the pediatric population for many of the disease-modifying treatments (DMTs) approved for use in adults with MS. Our objective was to describe the demographic features and clinical and radiologic course of patients with POMS treated with the commonly used newer DMTs within the US Network of Pediatric MS Centers (NPMSC). METHODS This is an analysis of prospectively collected data from patients who initiated treatment before age 18 with the DMTs listed below at the 12 regional pediatric MS referral centers participating in the NPMSC. RESULTS One hundred sixty-eight patients on dimethyl fumarate, 96 on fingolimod, 151 on natalizumab, 166 on rituximab, and 37 on ocrelizumab met criteria for analysis. Mean age at DMT initiation ranged from 15.2 to 16.5 years. Disease duration at the time of initiation of index DMT ranged from 1.1 to 1.6 years with treatment duration of 0.9-2.0 years. Mean annualized relapse rate (ARR) in the year prior to initiating index DMT ranged from 0.4 to 1.0. Mean ARR while on index DMT ranged from 0.05 to 0.20. New T2 and enhancing lesions occurred in 75%-88% and 55%-73% of the patients, respectively, during the year prior to initiating index DMT. After initiating index DMT, new T2 and enhancing lesions occurred in 0%-46% and 11%-34% patients, respectively. Rates of NEDA-2 (no evidence of disease activity) ranged from 76% to 91% at 6 months of treatment with index DMTs and 66% to 84% at 12 months of treatment with index DMTs. CONCLUSIONS Though limited by relatively short treatment duration with the index DMTs, our data suggest clinical and MRI benefit, as well as high rates of NEDA-2, in a large number of POMS patients, which can be used to guide future studies in this population.

Abstract
BACKGROUND Paediatric-onset multiple sclerosis (POMS) is increasing worldwide and represents approximately 5% of all MS cases. Although this patient group has similar characteristics to the adult group, it is important for this patient group to receive effective treatment due to the early onset of cognitive involvement, higher lesion burden, and secondary progression at an earlier age than adults. In this study, we aimed to evaluate the factors that cause treatment change in POMS patients. MATERIAL AND METHOD Adult patients with a first MS attack at age 18 years or younger who were followed up with the diagnosis of MS at the Clinical Neuroimmunology and Demyelinating Diseases outpatient clinic of Cerrahpaşa Medical School between 1987 and 2020 were included in our study. Patient files were reviewed retrospectively, and demographic and clinical characteristics, imaging, first attack characteristics, and treatment change were noted. We included 269 patients with a definite diagnosis of MS in the study, and these patients were evaluated in two groups: negative for treatment change and positive for treatment change. RESULTS Multifocal involvement was detected more frequently in the group with treatment change (p = 0,049). Cerebellar involvement as a first attack symptom was more common in male patients (p = 0,023) The age at first MS attack was found to be younger (p = 0,006), and the disease duration was longer in the positive for treatment change group (p = 0,003). Spinal cord involvement was more common in the positive for treatment change group (p = 0,016). Abnormal VEP findings were observed more frequently in the group without treatment change (p = 0.018). In multivariant analysis, spinal cord involvement, younger age at first attack, and abnormal VEP findings in the group without treatment change were found to be significant. Among the reasons for treatment change, the most common reason was radiological and clinical progression. CONCLUSION The higher inflammatory load in POMS patients compared with adults necessitates early initiation of treatment in this group and timely treatment change to prevent disability. Furthermore, this patient group should be followed closely and receive effective treatment.

Abstract
OBJECTIVE To study the clinical course, the rate of progression and the results of the disease modifying treatment (DMT) in pediatric-onset multiple sclerosis (POMS) patients in the Voronezh region. MATERIAL AND METHODS The clinical characteristics of the course of relapsing-remitting multiple sclerosis (MS) were analyzed among 51 POMS patients and 51 patients with the adult-onset MS (AOMS). The clinical course was assessed based on the Expanded Disability Status Scale (EDSS) score, the average annual frequency of exacerbations and the rate of disease progression before and during DMT. RESULTS There were no statistically significant differences in EDSS scores 11 years after the onset of MS between the groups: POMS patients achieved moderate disability by the age of 25, and AOMS patients showed stabilization of their condition during DMT by the age of 36. During changing first-line drugs in patients with POMS, there was again an increase in disability with the transition of 25% of patients to the group with secondary progression of MS on average after 8 years of DMT. CONCLUSION The onset of the disease in children and adolescents leads to a significant decrease in their quality of life and the deterioration of all activities throughout their lives. To prevent the progression of the disease it seems appropriate to transfer patients with POMS immediately to second-line DMT when signs of a suboptimal response to first line DMT appear, and in the case of a rapidly progressive course to start therapy with second-line drugs.

Abstract
Teriflunomide (Aubagio®), which was developed by Sanofi, is an oral immunomodulatory agent targeting the mitochondrial enzyme dihydroorotate dehydrogenase and available to adults to treat relapsing-remitting multiple sclerosis (MS). On 18 June 2021, teriflunomide received its first approval in this indication in pediatric patients aged ≥ 10 years in the EU. This article summarizes the milestones in the development of teriflunomide leading to this first pediatric approval for relapsing-remitting MS.

Abstract
BACKGROUND Only recently has the first disease-modifying therapy been approved for children with multiple sclerosis (MS) and practice patterns including substantial off-label use have evolved. Understanding attitudes towards treatment of paediatric MS and whether this has changed due to the ongoing COVID-19 pandemic is vital to guide future therapeutic trials and for developing guidelines that reflect practice. METHODS We performed an online survey within the International Paediatric Multiple Sclerosis Study Group between July and September 2020. The survey was sent to 130 members from 25 countries and consisted of five sections: demographic data, treatment, disease modifying therapies and COVID-19, outcome and three patient cases. RESULTS The survey was completed by 66 members (51%), both paediatric neurologists and adult neurologists. Fingolimod and β-interferons were the most frequently used disease-modifying therapies, especially among paediatric neurologists. Almost a third (31%) of respondents had altered their prescribing practice due to COVID-19, in particular at the beginning of the pandemic. CONCLUSIONS The survey results indicate a tendency of moving from the traditional escalation therapy starting with injectables towards an early start with newer, highly effective disease modifying therapies. The COVID-19 pandemic only slightly affected prescribing patterns and treatment choices in paediatric MS.

Abstract
BACKGROUND A significant proportion of pediatric-onset multiple sclerosis (POMS) patients do not respond to first-line disease-modifying therapies. Clinical trials showed that natalizumab is effective and safe in adults, but there are limited clinical trial data for children. Natalizumab is currently prescribed off-label for POMS. We aimed to characterize the effectiveness, safety and tolerability of natalizumab in all POMS cases treated in Portugal (from 2007 to 2018). METHODS Data from clinical records were retrospectively collected for all POMS cases treated with natalizumab in Portugal. RESULTS Twenty-one patients were included, 14 (67%) of which were female. The median age at POMS diagnosis was 13 years old. The median duration of treatment with natalizumab was 2 years and 3 months. Median Expanded Disability Status Scale score decreased from 1.5 to 1.0 after 24 months. The Annualized Relapse Rate decreased from 1.31 events/patient/year before treatment with natalizumab to 0 after 12 months of treatment and to 0.04 after 24 months. No gadolinium-enhancing lesions or new or enlarged T2 hyperintense lesions were observed in 8/8 patients (100%) after 12 months, and 4/5 (80%) after 24 months. There was one possible serious adverse event, which did not require dose adjustment. Five patients discontinued treatment due to positive anti-JCV (JC virus) antibody JC serostatus. CONCLUSION Natalizumab may be an effective and safe disease-modifying therapy for POMS. Our results are in line with data published for the adult population, as well as with similar observational studies in pediatric populations in other regions.

Abstract
The natural history of multiple sclerosis (MS) is highly heterogeneous. A subgroup of patients has what might be termed aggressive MS. These patients may have frequent, severe relapses with incomplete recovery and are at risk of developing greater and permanent disability at the earlier stages of the disease. Their therapeutic window of opportunity may be narrow, and while it is generally considered that they will benefit from starting early with a highly efficacious treatment, a unified definition of aggressive MS does not exist and data on its treatment are largely lacking. Based on discussions at an international focused workshop sponsored by the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS), we review our current knowledge about treatment of individuals with aggressive MS. We analyse the available evidence, identify gaps in knowledge and suggest future research needed to fill those gaps. A companion paper details the difficulties in developing a consensus about what defines aggressive MS.

Abstract
OBJECTIVE To assess real-world effectiveness of initial treatment with newer compared to injectable disease-modifying therapies (DMTs) on disease activity in pediatric multiple sclerosis (MS) and clinically isolated syndrome (CIS). METHODS This is a cohort study of children with MS/CIS followed at 12 clinics in the US Network of Pediatric MS Centers, who received initial therapy with newer (fingolimod, dimethyl fumarate, teriflunomide, natalizumab, rituximab, ocrelizumab) or injectable (interferon-β, glatiramer acetate) DMTs. Propensity scores (PSs) were computed, including preidentified confounders. Relapse rate while on initial DMT was modeled with negative binomial regression, adjusted for PS-quintile. Time to new/enlarging T2-hyperintense and gadolinium-enhancing lesions on brain magnetic resonance imaging were modeled with midpoint survival analyses, adjusted for PS-quintile. RESULTS A total of 741 children began therapy before 18 years, 197 with newer and 544 with injectable DMTs. Those started on newer DMTs were older (15.2 vs injectable 14.4 years, p = 0.001) and less likely to have a monofocal presentation. In PS-quintile-adjusted analysis, those on newer DMTs had a lower relapse rate than those on injectables (rate ratio = 0.45, 95% confidence interval (CI) = 0.29-0.70, p < 0.001; rate difference = 0.27, 95% CI = 0.14-0.40, p = 0.004). One would need to treat with newer rather than injectable DMTs for 3.7 person-years to prevent 1 relapse. Those started on newer DMTs had a lower rate of new/enlarging T2 (hazard ratio [HR] = 0.51, 95% CI = 0.36-0.72, p < 0.001) and gadolinium-enhancing lesions (HR = 0.38, 95% CI = 0.23-0.63, p < 0.001) than those on injectables. INTERPRETATION Initial treatment of pediatric MS/CIS with newer DMTs led to better disease activity control compared to injectables, supporting greater effectiveness of newer therapies. Long-term safety data for newer DMTs are required. ANN NEUROL 2020 ANN NEUROL 2020;88:42-55.

Abstract
Pediatric-onset multiple sclerosis (POMS) is an immune-mediated, demyelinating, neurodegenerative disease that accounts for 3-5% of all multiple sclerosis (MS) cases. Although evidence suggests that it has similar risk factors and disease pathophysiology as adult-onset MS (AOMS), there are distinctive features in disease characteristics and patient demographics of POMS that require unique therapeutic development and treatment considerations. Gilenya® (Novartis International AG, Basel, Switzerland) (fingolimod) is a sphingosine-1-phosphate (S1P) receptor modulator that prevents lymphocytic outflow from peripheral lymph nodes. It has demonstrated efficacy in AOMS. In POMS, there have been three observational studies and one pivotal clinical trial evaluating the efficacy, safety, and tolerability of fingolimod. Currently, fingolimod is the only Food and Drug Administration and European Medicines Agency approved disease-modifying therapy to treat POMS. This review will critically evaluate the available evidence of fingolimod in the treatment of POMS in detail, as well as discussing its treatment implications.

Abstract
PURPOSE OF REVIEW With the recognition that pediatric-onset multiple sclerosis (POMS) is characterized by more prominent disease activity, earlier age at onset of disability milestones, and more prominent cognitive impairment compared with physical disability earlier in the disease course compared with adult-onset multiple sclerosis (AOMS), there has been increasing interest in identifying optimal and safe treatment approaches to achieve better disease control in this group. Injectable therapies have been traditionally used as first line in this population, although not formally approved. This review focuses on current treatment and monitoring approaches in POMS. RECENT FINDINGS In the past few years, and despite the paucity of FDA-approved medications for use in POMS, an increasing trend toward using newer disease-modifying therapies (DMTs) in this group is observed. However, escalation (as opposed to induction) remains the most frequent approach, and many children continue to be untreated before age 18, particularly before age 12. The only FDA- and EMA-approved disease-modifying therapy in POMS is fingolimod; however, dimethyl fumarate, teriflunomide, natalizumab, ocrelizumab, and alemtuzumab either have been evaluated in observational studies or are being currently investigated in formal randomized controlled trials for use in POMS and appear to be safe in this group. Autologous hematopoietic stem cell transplantation has also been evaluated in a small series. Clinical outcome measures and MS biomarkers have been poorly studied in POMS; however, the use of composite functional scores, neurofilament light chain, optical coherence tomography, and imaging findings is being increasingly investigated to improve early diagnosis and efficient monitoring of POMS. Off-label use of newer DMTs in POMS is increasing, and based on retrospective data, and phase 2 trials, this approach appears to be safe in children. Results from ongoing trials will help clarify the safety and efficacy of these therapies in the future. Fingolimod is the only FDA-approved medication for use in POMS. Outcome measures and biomarkers used in AOMS are being studied in POMS and are greatly needed to quantify treatment response in this group.

Abstract
Multiple sclerosis is a chronic immune-mediated demyelinating disease of the central nervous system. The diagnosis of multiple sclerosis in children, as in adults, requires evidence of dissemination of inflammatory activity in more than one location in the central nervous system (dissemination in space) and recurrent disease over time (dissemination in time). The identification of myelin oligodendrocyte glycoprotein antibodies (MOG-Ab) and aquaporin-A antibodies (AQP4-Ab), and the subsequent discovery of their pathogenic mechanisms, have led to a shift in the classification of relapsing demyelinating syndromes. This is reflected in the 2017 revised criteria for the diagnosis of multiple sclerosis, which emphasizes the exclusion of multiple sclerosis mimics and aims to enable earlier diagnosis and thus treatment initiation. The long-term efficacy of individual therapies initiated in children with multiple sclerosis is hard to evaluate, owing to the small numbers of patients who have the disease, the relatively high number of patients who switch therapy, and the need for long follow-up studies. Nevertheless, an improvement in prognosis with a globally reduced annual relapse rate in children with multiple sclerosis is now observed compared with the pretreatment era, indicating a possible long-term effect of therapies. Given the higher relapse rate in children compared with adults, and the impact multiple sclerosis has on cognition in the developing brain, there is a question whether rapid escalation or potent agents should be used in children, while the short- and long-term safety profiles of these drugs are being established. With the results of the first randomized controlled trial of fingolimod versus interferon-β1a in paediatric multiple sclerosis published in 2018 and several clinical trials underway, there is hope for further progress in the field of paediatric multiple sclerosis. WHAT THIS PAPER ADDS: Early and accurate diagnosis of multiple sclerosis is crucial. The discovery of antibody-mediated demyelination has changed the diagnosis and management of relapsing demyelination syndromes. Traditional escalation therapy is being challenged by induction therapy.

Abstract
Multiple sclerosis (MS) presenting in the pediatric years can lead to landmark disability levels younger in life than adult onset MS and so therefore early and effective treatment remains paramount for long-term outcomes. The goals of MS therapeutics in adults have widened to address multiple mechanisms: anti-inflammatory, neuroprotective, and myelin repair, yet the optimal paradigm for MS therapies in the pediatric population is not known. Pediatric onset MS add complexities due to the ongoing development of the central nervous system and the immune system. Clinical trials have led to an increasing number of pharmaceutical therapies for adult onset MS (AOMS), one POMS randomized controlled trial is completed and other trials are ongoing, yet due to the low prevalence of POMS, the dynamic landscape and risk management of the MS disease modifying therapies (DMT) it remains more difficult to complete trials in POMS. There is consensus that controlled clinical trials leading to appropriate and safe therapies for POMS are important for a multitude of reasons that include unique pediatric pharmacokinetics, short and long-term safety, developmental issues, clinical benefits, and regulatory approval.
