BACKGROUND: Evobrutinib, a Bruton's tyrosine kinase (BTK) inhibitor, has shown preliminary efficacy in people with relapsing multiple sclerosis in a phase 2 trial. Here, we aimed to compare the safety and efficacy of evobrutinib with the active comparator teriflunomide in people with relapsing multiple sclerosis. METHODS: EvolutionRMS1 and evolutionRMS2 were two multicentre, randomised, double-blind, double-dummy, active-controlled, phase 3 trials conducted at 701 multiple sclerosis centres and neurology clinics in 52 countries. Adults aged 18-55 years with relapsing multiple sclerosis (Expanded Disability Status Scale [EDSS] score of 0·0-5·5) were included. Participants were randomly assigned (1:1) using a central interactive web response system to receive either evobrutinib (45 mg twice per day with placebo once per day) or teriflunomide (14 mg once per day with placebo twice per day), all taken orally and in an unfasted state, with randomisation stratified by geographical region and baseline EDSS. All study staff and participants were masked to the study interventions. The primary endpoint for each study was annualised relapse rate based on adjudicated qualified relapses up to 156 weeks, assessed in the full analysis set (defined as all randomly assigned participants) with a negative binomial model. These studies are registered with ClinicalTrials.gov (NCT04338022 for evolutionRMS1 and NCT04338061 for evolutionRMS2, both are terminated). FINDINGS: The primary analysis was done using data for 2290 randomly assigned participants collected from June 12, 2020, to Oct 2, 2023. 1124 participants were included in the full analysis set in evolutionRMS1 (560 in the evobrutinib group and 564 in the teriflunomide group) and 1166 in evolutionRMS2 (583 in each group). 751 (66·8%) participants were female and 373 (33·1%) were male in evolutionRMS1, whereas 783 (67·2%) were female and 383 (32·8%) were male in evolutionRMS2. Annualised relapse rate was 0·15 (95% CI 0·12-0·18 with evobrutinib vs 0·14 [0·11-0·18] with teriflunomide (adjusted RR 1·02 [0·75-1·39]; p=0·55) in evolutionRMS1 and 0·11 (0·09-0·13 vs 0·11 [0·09-0·13]; adjusted RR 1·00 [0·74-1·35]; p=0·51) in evolutionRMS2. The pooled proportion of participants with any treatment-emergent adverse event (TEAE) was similar between treatment groups (976 [85·6%] of 1140 with evobrutinib vs 999 [87·2%] of 1146 with teriflunomide). The most frequently reported TEAEs were COVID-19 (223 [19·6%] with evobrutinib vs 223 [19·5%] with teriflunomide), alanine aminotransferase increased (173 [15·2%] vs 204 [17·8%]), aspartate aminotransferase increased (110 [9·6%] vs 131 [11·4%]), and headache (175 [15·4%] vs 176 [15·4%]). Serious TEAE incidence rates were higher with evobrutinib than teriflunomide (86 [7·5%] vs 64 [5·6%]). Liver enzyme elevations at least 5 × upper limit of normal were more common with evobrutinib than with teriflunomide, particularly in the first 12 weeks (55 [5·0%] vs nine [<1%]). Three people who received evobrutinib and one who received teriflunomide met the biochemical definition of Hy's law; all cases resolved after discontinuation of treatment. There were two deaths (one in each group), neither related to study treatment. INTERPRETATION: The efficacy of evobrutinib was not superior to that of teriflunomide. Together, efficacy and liver-related safety findings do not support the use of evobrutinib in people with relapsing multiple sclerosis. FUNDING: Merck.

Background: Multiple sclerosis (MS) is threefold more prevalent in women than men. However, sex-specific efficacy analysis for MS disease-modifying therapies is not typically performed. Methods:Post hoc analyses of data from female patients enrolled in the phase 3, double-blind OPTIMUM study of relapsing MS were carried out. Eligible adults were randomized to ponesimod 20 mg or teriflunomide 14 mg once daily for up to 108 weeks. The primary endpoint was annualized relapse rate (ARR); secondary endpoints included change in symptom domain of Fatigue Symptom and Impact Questionnaire-Relapsing Multiple Sclerosis (FSIQ-RMS) at week 108, number of combined unique active lesions (CUALs) per year on magnetic resonance imaging, and time to 12- and 24-week confirmed disability accumulation (CDA). Results: A total of 735 female patients (581 of childbearing potential) were randomized to ponesimod (n = 363, 49.4%) or teriflunomide (n = 372, 50.6%). Relative risk reduction in the ARR for ponesimod versus teriflunomide was 33.1% (mean, 0.192 vs. 0.286, respectively; p < 0.002). Mean difference in FSIQ-RMS for ponesimod versus teriflunomide was -4.34 (0.12 vs. 4.46; p = 0.002); rate ratio in CUALs per year, 0.601 (1.45 vs. 2.41; p < 0.0001), and hazard ratio for time to 12- and 24-week CDA risk estimates, 0.83 (10.7% vs. 12.9%; p = 0.38) and 0.91 (8.8% vs. 9.7%; p = 0.69), respectively. Incidence of treatment-emergent adverse events was similar between treatment groups (89.0% and 90.1%). Conclusions: Analyses demonstrate the efficacy and safety of ponesimod, versus active comparator, for women with relapsing MS, supporting data-informed decision-making for women with MS. Clinical Trial Registration Number: NCT02425644.

BACKGROUND: Teriflunomide is administered orally to treat relapsing-remitting multiple sclerosis. In this prospective pilot study, the free and total serum concentrations of teriflunomide obtained during routine health care were measured and their relationship with disease activity was evaluated. METHODS: Eighty-nine patients were included in this study. Blood samples were collected from April 2021 to February 2022, and free and total teriflunomide serum concentrations were measured. Patient assessment involved monitoring of blood counts and potential adverse effects of teriflunomide. RESULTS: In the steady-state group, total teriflunomide concentrations ranged from 14.7 to 144.2 mg/L, while free concentrations from 31.1 to 389.7 μg/L. In the non-steady-state group, the total concentration ranged from 2.2 to 59.3 mg/L, with free concentrations ranging from 6.8 to 143.5 μg/L. In the steady-state group, a significant inverse correlation was found between absolute peripheral blood lymphocyte count and both total and free teriflunomide serum concentrations. CONCLUSION: Although all patients were treated with the same dose, up to a 10-fold difference in total and free teriflunomide serum concentrations, and up to a 5-fold difference in steady-state trough concentrations were observed. This vast interindividual variability can potentially lead to toxicity or, conversely, to suboptimal therapeutic concentrations of teriflunomide, with the risk of further worsening of multiple sclerosis compensation.

BACKGROUND: Promotion of myelin repair in the context of demyelinating diseases such as multiple sclerosis (MS) still represents a clinical unmet need, given that this disease is not only characterized by autoimmune activities but also by impaired regeneration processes. Hence, this relates to replacement of lost oligodendrocytes and myelin sheaths-the primary targets of autoimmune attacks. Endogenous remyelination is mainly mediated via activation and differentiation of resident oligodendroglial precursor cells (OPCs), whereas its efficiency remains limited and declines with disease progression and aging. Teriflunomide has been approved as a first-line treatment for relapsing remitting MS. Beyond its role in acting via inhibition of de novo pyrimidine synthesis leading to a cytostatic effect on proliferating lymphocyte subsets, this study aims to uncover its potential to foster myelin repair. METHODS: Within the cuprizone mediated de-/remyelination model teriflunomide dependent effects on oligodendroglial homeostasis and maturation, related to cellular processes important for myelin repair were analyzed in vivo. Teriflunomide administration was performed either as pulse or continuously and markers specific for oligodendroglial maturation and mitochondrial integrity were examined by means of gene expression and immunohistochemical analyses. In addition, axon myelination was determined using electron microscopy. RESULTS: Both pulse and constant teriflunomide treatment efficiently boosted myelin repair activities in this model, leading to accelerated generation of oligodendrocytes and restoration of myelin sheaths. Moreover, teriflunomide restored mitochondrial integrity within oligodendroglial cells. CONCLUSIONS: The link between de novo pyrimidine synthesis inhibition, oligodendroglial rescue, and maintenance of mitochondrial homeostasis appears as a key for successful myelin repair and hence for protection of axons from degeneration.

BACKGROUND: The monoclonal antibody ublituximab enhances antibody-dependent cellular cytolysis and produces B-cell depletion. Ublituximab is being evaluated for the treatment of relapsing multiple sclerosis. METHODS: In two identical, phase 3, double-blind, double-dummy trials (ULTIMATE I and II), participants with relapsing multiple sclerosis were randomly assigned in a 1:1 ratio to receive intravenous ublituximab (150 mg on day 1, followed by 450 mg on day 15 and at weeks 24, 48, and 72) and oral placebo or oral teriflunomide (14 mg once daily) and intravenous placebo. The primary end point was the annualized relapse rate. Secondary end points included the number of gadolinium-enhancing lesions on magnetic resonance imaging (MRI) by 96 weeks and worsening of disability. RESULTS: A total of 549 participants were enrolled in the ULTIMATE I trial, and 545 were enrolled in the ULTIMATE II trial; the median follow-up was 95 weeks. In the ULTIMATE I trial, the annualized relapse rate was 0.08 with ublituximab and 0.19 with teriflunomide (rate ratio, 0.41; 95% confidence interval [CI], 0.27 to 0.62; P<0.001); in the ULTIMATE II trial, the annualized relapse rate was 0.09 and 0.18, respectively (rate ratio, 0.51; 95% CI, 0.33 to 0.78; P = 0.002). The mean number of gadolinium-enhancing lesions was 0.02 in the ublituximab group and 0.49 in the teriflunomide group (rate ratio, 0.03; 95% CI, 0.02 to 0.06; P<0.001) in the ULTIMATE I trial and 0.01 and 0.25, respectively (rate ratio, 0.04; 95% CI, 0.02 to 0.06; P<0.001), in the ULTIMATE II trial. In the pooled analysis of the two trials, 5.2% of the participants in the ublituximab group and 5.9% in the teriflunomide group had worsening of disability at 12 weeks (hazard ratio, 0.84; 95% CI, 0.50 to 1.41; P = 0.51). Infusion-related reactions occurred in 47.7% of the participants in the ublituximab group. Serious infections occurred in 5.0% in the ublituximab group and in 2.9% in the teriflunomide group. CONCLUSIONS: Among participants with relapsing multiple sclerosis, ublituximab resulted in lower annualized relapse rates and fewer brain lesions on MRI than teriflunomide over a period of 96 weeks but did not result in a significantly lower risk of worsening of disability. Ublituximab was associated with infusion-related reactions. (Funded by TG Therapeutics; ULTIMATE I and II ClinicalTrials.gov numbers, NCT03277261 and NCT03277248.).

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

Sclerosis multiplex (SM) je autoimunitné ochorenie centrálneho nervového systému. V súčasnosti máme k dispozícii pomerne širokú škálu ochorenie modifikujúcich liečiv (Disease Modifying Therapy - DMT) s rôznym mechanizmom účinku a účinnosťou. Na dosiahnutie čo najlepšieho liečebného ovplyvnenia ochorenia je potrebný individuálny prístup pri výbere liečby. Je potrebné mať na pamäti aj riziká zvolenej liečby pre daného pacienta. Kontinuálne klinické, ako aj laboratórne monitorovanie pacientov je nevyhnutné.

Currently, we have a fairly wide range of disease - modifying drugs (DMD) with different mechanisms of action and different efficiencies. To obtain the most efficient therapeutic results we need to choose an individual approach for appropriate therapy. It is also very important to keep in mind the risk of this therapy for appropriate patient. The continual clinical and laboratory monitoring of the patients is unavoidable.
