BACKGROUND: Limited licensed medications are available for multiple sclerosis (MS) in pediatric patients. OBJECTIVE: To evaluate the efficacy, safety, and tolerability of alemtuzumab in pediatric patients with relapsing-remitting multiple sclerosis (RRMS) and disease activity on prior disease-modifying therapies (DMTs). METHODS: LemKids was a multicenter, multinational, single-arm, open-label, switch (from ongoing DMT to alemtuzumab treatment) study in pediatric RRMS patients (aged 10-<18 years), with disease activity on DMT. The primary endpoint was a comparison of the number of new/enlarging T2 lesions on the magnetic resonance imaging of the brain between the prior-DMT period and alemtuzumab treatment. RESULTS: This study was prematurely terminated due to low enrollment and an European Medicines Agency Article-20 pharmacovigilance review of alemtuzumab in adult RRMS. Of 46 screened patients, 16 were enrolled; 12 completed prior-DMT treatment period; 11 received alemtuzumab of whom 7 completed treatment. Patients on alemtuzumab developed fewer new/enlarging T2 lesions compared with prior-DMT (7 vs 178, relative risk (95% confidence interval): 0.04 (0.01-0.14)). No significant pharmacodynamic changes or safety concerns were noted in this limited dataset. CONCLUSION: Alemtuzumab treatment was associated with a low number of new/enlarging T2 lesions in pediatric patients with RRMS and was safe and well tolerated in seven patients during infusion and the initial 4 months.

IMPORTANCE: Progression independent of relapse activity (PIRA) is a significant contributor to long-term disability accumulation in relapsing-remitting multiple sclerosis (MS). Prior studies have used varying PIRA definitions, hampering the comparability of study results. OBJECTIVE: To compare various definitions of PIRA. DESIGN, SETTING, AND PARTICIPANTS: This cohort study involved a retrospective analysis of prospectively collected data from the MSBase registry from July 2004 to July 2023. The participants were patients with MS from 186 centers across 43 countries who had clinically definite relapsing-remitting MS, a complete minimal dataset, and 3 or more documented Expanded Disability Status Scale (EDSS) assessments. EXPOSURE: Three-hundred sixty definitions of PIRA as combinations of the following criteria: baseline disability (fixed baseline with re-baselining after PIRA, or plus re-baselining after relapses, or plus re-baselining after improvements), minimum confirmation period (6, 12, or 24 months), confirmation magnitude (EDSS score at/above worsening score or at/above threshold compared with baseline), freedom from relapse at EDSS score worsening (90 days prior, 90 days prior and 30 days after, 180 days prior and after, since previous EDSS assessment, or since baseline), and freedom from relapse at confirmation (30 days prior, 90 days prior, 30 days before and after, or between worsening and confirmation). MAIN OUTCOME AND MEASURE: For each definition, we quantified PIRA incidence and persistence (ie, absence of a 3-month confirmed EDSS improvement over ≥5 years). RESULTS: Among 87 239 patients with MS, 33 303 patients fulfilled the inclusion criteria; 24 152 (72.5%) were female and 9151 (27.5%) were male. At the first visits, the mean (SD) age was 36.4 (10.9) years; 28 052 patients (84.2%) had relapsing-remitting MS, and the median (IQR) EDSS score was 2.0 (1.0-3.0). Participants had a mean (SD) 15.1 (11.9) visits over 8.9 (5.2) years. PIRA incidence ranged from 0.141 to 0.658 events per decade and persistence from 0.753 to 0.919, depending on the definition. In particular, the baseline and confirmation period influenced PIRA detection. The following definition yielded balanced incidence and persistence: a significant disability worsening compared with a baseline (reset after each PIRA event, relapse, and EDSS score improvement), in absence of relapses since the last EDSS assessment, confirmed with EDSS scores (not preceded by relapses within 30 days) that remained above the worsening threshold for at least 12 months. CONCLUSION AND RELEVANCE: Incidence and persistence of PIRA are determined by the definition used. The proposed standardized definition aims to enhance comparability among studies.

BACKGROUND AND OBJECTIVES: IV-administered ocrelizumab (OCR) is approved for the treatment of relapsing and primary progressive multiple sclerosis (RMS/PPMS). OCARINA II (NCT05232825) was designed to demonstrate noninferiority in drug exposure of OCR subcutaneous (SC) vs IV administration. METHODS: This phase 3, randomized, open-label study enrolled OCR-naive patients aged 18-65 years with RMS/PPMS and an Expanded Disability Status Scale score of 0-6.5. Patients received OCR IV 600 mg or OCR SC 920 mg (controlled period), followed by OCR SC 920 mg every 24 weeks, up to week 96 (OCR IV/SC and OCR SC/SC). The primary end point was OCR area under the serum concentration-time curve from day 1 to week 12 (AUCW1‒12); other end points included clinical, biomarker, and pharmacodynamic outcomes and safety data. RESULTS: Baseline demographics were balanced across OCR IV/SC and OCR SC/SC arms (N = 118/118, 40.0 ± 11.9/39.9 ± 11.4 years, 59.3%/65.3% female, 89.0%/89.0% with RMS). The study demonstrated noninferiority of OCR SC 920 mg to OCR IV 600 mg for the primary end point AUCW1-12 and also over the dosing interval for AUCW1‒24 (geometric mean ratios [90% CI] 1.29 [1.23-1.35] and 1.27 [1.21-1.34], respectively). At week 48, 111 of 118 (OCR IV/SC) and 114 of 118 (OCR SC/SC) had received OCR SC. A near-complete suppression of MRI activity was reported in OCR IV/SC and OCR SC/SC: 0 of 113 and 0 of 113 patients had T1 lesions while 1 of 114 and 1 of 113 had 2 and 1 new/enlarging T2 lesions, respectively. Two patients (1.9%) in each arm had 1 relapse, and 1 patient (0.9%; OCR SC/SC) had 2 relapses. In both arms, rapid and sustained B-cell depletion was observed and serum neurofilament light chain reduction was comparable. Patients receiving at least 1 dose of OCR SC 920 mg in the OCR IV/SC and OCR SC/SC arms reported adverse events (AEs): 75.4% and 86.4%, and serious AEs: 5.9% and 2.5%. The most frequently reported AEs were injection reactions (IRs, 51.5%); local and systemic IRs were experienced by 117 of 233 patients (50.2%) and 27 of 233 patients (11.6%), respectively. All IRs were mild/moderate; intensity and duration decreased with subsequent injections. DISCUSSION: The OCR SC formulation demonstrated noninferiority to OCR IV formulation regarding drug exposure, providing comparable efficacy and safety and an additional treatment option for patients with multiple sclerosis. CLASSIFICATION OF EVIDENCE: This study provides Class II evidence that a single SC injection of 920 mg of OCR achieves a noninferior 12-week area under serum concentration-time curve to that of 2 IV infusions of 300-mg OCR administered 2 weeks apart.

INTRODUCTION: The efficacy of anti-CD20 antibodies has significantly contributed to advancing our understanding of disease pathogenesis and improved treatment outcomes in relapsing-remitting multiple sclerosis (RRMS). A comprehensive analysis of the peripheral immune cell profile, combined with prospective clinical characterization, of RRMS patients treated with ocrelizumab (OCR) or ofatumumab (OFA) was performed to further understand immune reconstitution following B-cell depletion. METHODS: REBELLION-MS is a longitudinal analysis of RRMS patients treated with either OCR (n = 34) or OFA (n = 25). Analysis of B, T, natural killer (NK) and natural killer T (NKT) cells at baseline, month 1, and 12 was performed by multidimensional flow cytometry. Data were analyzed by conventional gating and unsupervised computational approaches. In parallel, different clinical parameters were longitudinally assessed. Twenty treatment-naïve age/sex-matched RRMS patients were included as the control cohort. RESULTS: B-cell depletion by OCR and OFA resulted in significant reductions in CD20+ T and B cells as well as B-cell subsets, alongside an expansion of CD5+CD19+CD20- B cells, while also elevating exhaustion markers (CTLA-4, PD-1, TIGIT, TIM-3) across T, B, NK, and NKT cells. Additionally, regulatory T-cell (TREG) numbers increased, especially in OCR-treated patients, and reductions in double-negative (CD3+CD4-CD8-) T cells (DN T cells) were observed, with these DN T cells having higher CD20 expression compared to CD4 or CD8 positive T cells. These immune profile changes correlated with clinical parameters, suggesting pathophysiological relevance in RRMS. CONCLUSIONS: Our interim data add weight to the argumentation that the exhaustion/activation markers, notably TIGIT, may be relevant to the pathogenesis of MS. In addition, we identify a potentially interesting increase in the expression of CD5+ on B cells. Finally, we identified a population of double-negative T cells (KLRG1+HLADR+, in particular) that is associated with MS activity and decreased with CD20 depletion.

BACKGROUND: In relapsing-remitting multiple sclerosis (RRMS), extended exposure to high-efficacy disease modifying therapy may increase the risk of side effects, compromise treatment adherence, and inflate medical costs. Treatment de-escalation, here defined as a switch to a lower efficacy therapy, is often considered by patients and physicians, but evidence to guide such decisions is scarce. In this study, we aimed to compare clinical outcomes between patients who de-escalated therapy versus those who continued their therapy. METHODS: In this retrospective analysis of data from an observational, longitudinal cohort of 87,239 patients with multiple sclerosis (MS) from 186 centers across 43 countries, we matched treatment episodes of adult patients with RRMS who underwent treatment de-escalation from either high- to medium-, high- to low-, or medium- to low-efficacy therapy with counterparts that continued their treatment, using propensity score matching and incorporating 11 variables. Relapses and 6-month confirmed disability worsening were assessed using proportional and cumulative hazard models. RESULTS: Matching resulted in 876 pairs (de-escalators: 73% females, median [interquartile range], age 40.2 years [33.6, 48.8], Expanded Disability Status Scale [EDSS] 2.5 [1.5, 4.0]; non-de-escalators: 73% females, age 40.8 years [35.5, 47.9], and EDSS 2.5 [1.5, 4.0]), with a median follow-up of 4.8 years (IQR 3.0, 6.8). Patients who underwent de-escalation faced an increased hazard of future relapses (hazard ratio 2.36 and 95% confidence intervals [CI] [1.79-3.11], p < 0.001), which was confirmed when considering recurrent relapses (2.43 [1.97-3.00], p < 0.001). It was also consistent across subgroups stratified by age, sex, disability, disease duration, and time since last relapse. CONCLUSIONS: On the basis of this observational analysis, de-escalation may not be recommended as a universal treatment strategy in RRMS. The decision to de-escalate should be considered on an individual basis, as its safety is not clearly guided by specific patient or disease characteristics evaluated in this study.

BACKGROUND: Cognitive impairment is a well-recognized symptom of multiple sclerosis (MS) that can manifest early in the disease course. Deficits in cognitive function can have a major impact on daily life. However, cognitive decline is often under-examined in clinical trials and clinical practice due to lack of adequate data. The objective of this study was to examine the longitudinal effect of ocrelizumab vs interferon beta (IFNβ)-1a on cognitive impairment in 2 phase 3 studies in relapsing MS (RMS). METHODS: The pooled population of participants with RMS (n = 1656) from the OPERA I/II clinical trials received subcutaneous IFNβ-1a (44 μg; n = 829) 3 times weekly or intravenous ocrelizumab (600 mg; n = 827) every 24 weeks. Cognition was assessed with a Symbol Digit Modalities Test (SDMT), administered in written or oral form according to each site investigator's choice, that primarily measured cognitive processing speed at baseline and every 12 weeks until the end of the double-blind treatment (96 weeks). Treatment effects were investigated based on longitudinal linear models for the change from baseline in SDMT and Cox regression for the time to 12- or 24-week confirmed decline of ≥4 points. RESULTS: Among the participants with an SDMT assessment at baseline and ≥1 postbaseline time point (IFNβ-1a, n = 749; ocrelizumab, n = 766), ocrelizumab treatment was associated with a greater mean SDMT improvement over 96 weeks than IFNβ-1a treatment (5.4 [95 % CI, 4.4-6.5] vs 4.0 [95 % CI, 3.0-5.1]; adjusted mean difference, 1.4 [95 % CI, 0.05-2.72]; P = 0.042). The risk of a clinically meaningful SDMT decline (≥4 points) was lower for those treated with ocrelizumab for both ≥12 weeks (IFNβ-1a, 18.4 %; ocrelizumab, 12.7 %; hazard ratio, 0.63 [95 % CI, 0.47-0.85]; P = 0.003) and ≥24 weeks (IFNβ-1a, 12.9 %; ocrelizumab, 7.9 %; HR, 0.57 [95 % CI, 0.39-0.82]; P = 0.003). CONCLUSION: Ocrelizumab treatment resulted in better cognitive outcomes as measured by SDMT in participants with RMS compared with IFNβ-1a treatment. However, methodological limitations need to be considered when interpreting these data. CLINICALTRIALS: gov: NCT01247324, NCT01412333.

BACKGROUND AND OBJECTIVES: Patients with multiple sclerosis (MS) may demonstrate better disease control when treatment is initiated on high-efficacy disease-modifying therapies (DMTs) from onset. This subgroup analysis assessed the long-term efficacy and safety profile of the high-efficacy DMT ocrelizumab (OCR) as first-line therapy for early-stage relapsing MS (RMS). METHODS: Post hoc exploratory analyses of efficacy and safety were performed in a subgroup of treatment-naive patients with RMS who received ≥1 dose of OCR in the multicenter OPERA I/II (NCT01247324/NCT01412333) studies. Patients were randomized to OCR or interferon β-1a for 96 weeks (double-blind controlled treatment period [DBP]), before switching to OCR in the open-label extension (OLE). Efficacy assessments included no evidence of disease activity (NEDA-3), 24-week confirmed disability progression (CDP), MRI lesion activity, change in whole-brain volume; with safety outcomes assessed over a 9-year treatment period. RESULTS: Overall, 757 patients were included (interferon-treated n = 382, mean age 36.3 years, 65.7% female; OCR-treated n = 375, mean age 35.5 years, 64.0% female); 505 of 757 (66.7%) completed 9 years of follow-up. The difference in NEDA status between OCR-treated and interferon-treated patients achieved during the DBP (72.5% and 43.8%, respectively, odds ratio 3.48, 95% CI 2.52-4.81) was maintained throughout the 7-year OLE (48.2% vs 25.7%; odds ratio 2.72, 95% CI 1.94-3.82). No 24-week CDP was observed in 78.7% of OCR-treated patients over 9 years. Brain volume loss over the entire study period remained numerically higher among patients starting OCR later (p = 0.09 at OLE at week 336). During the DBP, safety profiles in both groups were similar; no new safety signals were observed during the OLE. Over >9 years of continuous OCR treatment, the rate of infections remained low and stable over time. DISCUSSION: A higher proportion of OCR-treated patients achieved NEDA status compared with interferon-treated patients during the DBP, which was maintained throughout the OLE. After switching to OCR, disability accrual and brain volume loss among interferon-treated patients became similar to the OCR-OCR group, but disability and brain volume loss accrued during interferon treatment were not recovered. Possible study limitations include assessment bias due to unmaintained blinding during the OLE. These data support OCR as first-line therapy for these patients. CLASSIFICATION OF EVIDENCE: This study provides Class II evidence that OCR delays disease progression in treatment-naïve patients with early-stage RMS.

BACKGROUND: Natalizumab is a humanized monoclonal antibody administered at a fixed dose of 300 mg intravenously or subcutaneously every 4-6 weeks to treat relapsing-remitting multiple sclerosis. In this prospective cross-sectional study, natalizumab serum concentrations obtained during routine healthcare were measured, and the relationships between different routes of administration, sampling times, body characteristics, changes in blood count, and presence of anti-natalizumab antibodies were evaluated. METHODS: Ninety-two patients were included in this study. Blood samples were collected 0-48 days after administration, and natalizumab serum and anti-natalizumab antibody concentrations, as well as blood counts were measured. Subsequently, patients were divided into three groups according to the collection time after natalizumab administration. RESULTS: During the entire monitored period, serum natalizumab concentrations ranged from 1.8 to 193.3 μg/mL and 1.8 to 100.3 μg/mL after intravenous and subcutaneous administrations, respectively. A significant inverse correlation was found between serum natalizumab concentrations and differential and absolute peripheral blood neutrophil counts, erythrocyte counts, and hemoglobin concentrations. CONCLUSION: Although all patients were treated with the same dose, a 30-fold difference in serum natalizumab concentrations was observed. This wide inter-individual variability can potentially lead to an increased risk of natalizumab adverse events or, conversely, suboptimal therapeutic concentrations with the risk of further worsening of multiple sclerosis.

Tato kazuistika popisuje léčbu pacienta s relabující-remitující formou roztroušené sklerózy (RR-RS), který zároveň trpí Crohnovou nemocí. Po počáteční terapii glatiramer-acetátem a interferonem beta-1a došlo u pacienta k pokračující aktivitě onemocnění, která si vyžádala změnu léčby. S ohledem na potřebu vysoce účinné terapie a pacientovu preferenci méně častých návštěv zdravotnického zařízení byla v dubnu 2022 zahájena léčba ponesimodem. Po více než dvouleté léčbě pacient zůstává klinicky stabilní, bez nových atak či progrese nemoci, a Crohnova nemoc je v remisi. Pacient dobře toleruje léčbu a vede plnohodnotný život, což potvrzuje účinnost a bezpečnost ponesimodu jako vhodné volby pro pacienty s aktivní RS a komorbiditami.

This case report describes the treatment of a patient with relapsing-remitting multiple sclerosis (RR-RS) who also suffers from Crohn's disease. After initial therapy with glatiramer acetate and interferon beta-1a, the patient had ongoing disease activity that required a change in treatment. Considering the need for highly effective therapy and the patient's preference for less frequent visits to the medical facility, treatment with ponesimod was started in April 2022. After more than two years of treatment, the patient remains clinically stable, without new relapses or disease progression, and Crohn's disease is in remission. The patient tolerates the treatment well and leads a full life, which confirms the efficacy and safety of ponesimod as a suitable choice for patients with active MS and comorbidities.
