Human Umbilical Cord-Derived Mesenchymal Stem Cells in the Treatment of Multiple Sclerosis Patients: Phase I/II Dose-Finding Clinical Study. Cell Transplant 2024; 33:9636897241233045. [PMID: 38450623 PMCID: PMC10921855 DOI: 10.1177/09636897241233045] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/12/2023] [Revised: 01/08/2024] [Accepted: 01/31/2024] [Indexed: 03/08/2024] Open
Abstract
Multiple sclerosis (MS) is a chronic neuro-inflammatory disease resulting in disabilities that negatively impact patients' life quality. While current treatment options do not reverse the course of the disease, treatment using mesenchymal stromal/stem cells (MSC) is promising. There has yet to be a consensus on the type and dose of MSC to be used in MS. This work aims to study the safety and efficacy of two treatment protocols of MSCs derived from the umbilical cord (UC-MSCs) and their secretome. The study included two groups of MS patients; Group A received two intrathecal doses of UC-MSCs, and Group B received a single dose. Both groups received UC-MSCs conditioned media 3 months post-treatment. Adverse events in the form of a clinical checklist and extensive laboratory tests were performed. Whole transcriptome analysis was performed on patients' cells at baseline and post-treatment. Results showed that all patients tolerated the cellular therapy without serious adverse events. The general disability scale improved significantly in both groups at 6 months post-treatment. Examining specific aspects of the disease revealed more parameters that improved in Group A compared to Group B patients, including a significant increase in the (CD3+CD4+) expressing lymphocytes at 12 months post-treatment. In addition, better outcomes were noted regarding lesion load, cortical thickness, manual dexterity, and information processing speed. Both protocols impacted the transcriptome of treated participants with genes, transcription factors, and microRNAs (miRNAs) differentially expressed compared to baseline. Inflammation-related and antigen-presenting (HLA-B) genes were downregulated in both groups. In contrast, TNF-alpha, TAP-1, and miR142 were downregulated only in Group A. The data presented indicate that both protocols are safe. Furthermore, it suggests that administering two doses of stem cells can be more beneficial to MS patients. Larger multisite studies should be initiated to further examine similar or higher doses of MSCs.

The Potential Cost-Effectiveness of a Cell-Based Bioelectronic Implantable Device Delivering Interferon-β1a Therapy Versus Injectable Interferon-β1a Treatment in Relapsing-Remitting Multiple Sclerosis. PHARMACOECONOMICS 2022; 40:91-108.

Abstract
BACKGROUND Current first-line disease-modifying therapies (DMT) for multiple sclerosis (MS) patients are injectable or oral treatments. The Optogenerapy consortium is developing a novel bioelectronic cell-based implant for controlled release of beta-interferon (IFNβ1a) protein into the body. The current study estimated the potential cost effectiveness of the Optogenerapy implant (hereafter: Optoferon) compared with injectable IFNβ1a (Avonex). METHODS A Markov model simulating the costs and effects of Optoferon compared with injectable 30 mg IFNβ1a over a 9-year time horizon from a Dutch societal perspective. Costs were reported in 2019 Euros and discounted at a 4% annual rate; health effects were discounted at a 1.5% annual rate. The cohort consisted of 35-year-old, relapsing-remitting MS patients with mild disability. The device is implanted in a daycare setting, and is replaced every 3 years. In the base-case analysis, we assumed equal input parameters for Optoferon and Avonex regarding disability progression, health effects, adverse event probabilities, and acquisition costs. We assumed reduced annual relapse rates and withdrawal rates for Optoferon compared with Avonex. Sensitivity, scenario, value of information, and headroom analysis were performed. RESULTS Optoferon was the dominant strategy with cost reductions (- €26,966) and health gains (0.45 quality-adjusted life-years gained). A main driver of cost differences are the acquisition costs of Optoferon being 2.5 times less than the costs of Avonex. The incremental cost-effectiveness ratio was most sensitive to variations in the annual acquisition costs of Avonex, the annual withdrawal rate of Avonex and Optoferon, and the disability progression of Avonex. CONCLUSION Innovative technology such as the Optoferon implant may be a cost-effective therapy for patients with MS. The novel implantable mode of therapeutic protein administration has the potential to become a new mode of treatment administration for MS patients and in other disease areas. However, trials are needed to establish safety and effectiveness.

Abstract
Importance Treatment strategies for relapsing-remitting multiple sclerosis (RRMS) vary markedly between Denmark and Sweden. The difference in the association of these national strategies with clinical outcomes is unknown. Objective To investigate the association of national differences in disease-modifying treatment (DMT) strategies for RRMS with disability outcomes. Design, Setting, and Participants This cohort study used data on 4861 patients from the Danish and Swedish national multiple sclerosis (MS) registries from the date of index DMT initiation (between January 1, 2013, and December 31, 2016) until the last recorded visit at time of data extraction (October 2, 2019). Exposures All MS-specific DMTs initiated during the observation period were included in the analysis. Main Outcomes and Measures The primary study outcome was time to 24-week confirmed disability worsening. Secondary outcomes were 24-week confirmed disability improvement, milestone Expanded Disability Status Scale scores of 3 and 4, annualized relapse rate, time to first relapse, and treatment switching. Data were analyzed using inverse probability of treatment weighting-based models using a propensity score to weight and correct the comparison for the imbalance of confounders observed at baseline between the 2 countries. Results A total of 2700 patients from the Swedish MS registry (1867 women [69.2%]; mean [SD] age, 36.1 [9.5] years) and 2161 patients from the Danish MS registry (1472 women [68.1%]; mean [SD] age, 37.3 [9.4 years]) started a first DMT between 2013 and 2016, were included in the analysis, and were observed for a mean (SD) of 4.1 (1.5) years. A total of 1994 Danish patients (92.3%) initiated a low to moderately effective DMT (teriflunomide, 907 [42.0%]) and 165 (7.6%) initiated a highly effective DMT, whereas a total of 1769 Swedish patients (65.5%) initiated a low to moderately effective DMT (teriflunomide, 64 [2.4%]) and 931 (34.5%) initiated a highly effective DMT. The Swedish treatment strategy was associated with a 29% reduction in the rate of postbaseline 24-week confirmed disability worsening relative to the Danish treatment strategy (hazard ratio, 0.71; 95% CI, 0.57-0.90; P = .004). The Swedish treatment strategy was also associated with a 24% reduction in the rate of reaching an expanded disability status scale score of 3 (hazard ratio, 0.76; 95% CI, 0.60-0.97; P = .03) and a 25% reduction in the rate of reaching an expanded disability status scale score of 4 (hazard ratio, 0.75; 95% CI, 0.61-0.96; P = .01) relative to Danish patients. Conclusions and Relevance The findings of this study suggest that there is an association between differences in treatment strategies for RRMS and disability outcomes at a national level. Escalation of treatment efficacy was inferior to using more efficacious DMT as initial treatment.

An implantable device to treat multiple sclerosis: A discrete choice experiment on patient preferences in three European countries. J Neurol Sci 2021; 428:117587. [PMID: 34364148 DOI: 10.1016/j.jns.2021.117587] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2021] [Revised: 06/27/2021] [Accepted: 07/21/2021] [Indexed: 11/23/2022]
Abstract
BACKGROUND Persons with multiple sclerosis (MS) take their treatment via pills, injections or infusions. A novel mode of disease-modifying treatment administration, an implantable device, is under development. This study determined MS patient preferences for three modes of first-line treatment administration (implant, pills, injectables), and trade-offs regarding treatment characteristics. METHODS A survey including a discrete choice experiment was conducted among MS patients in the Netherlands, France, and the United Kingdom. Respondents had to repeatedly choose between various treatment scenarios with four treatment characteristics: risk of relapse, reduction of disease progression, risk of side effects and mode of administration. Data was analysed using a panel latent class logit model. RESULTS Based on the preferences of 753 MS patients (response rate 7%: 753/11202), two latent classes were identified (class probability of 74% vs 26%). Persons with relapsing-remitting MS and who administered medication via injections generally preferred any treatment over no treatment. Patients who could walk without an aid were more likely to prefer no treatment. Reducing disease progression was the most important treatment characteristic class 1. Mode of administration was the most important characteristic in class 2. Patients were willing to accept an increase in risk of relapse and disease progression to get their treatment via an implant rather than injections. Predicted uptake was the highest for the implant, followed by pills, injections, and no treatment. CONCLUSION We found that a drug-delivery implant could be a potential addition to the MS treatment landscape: MS patients are willing to trade-off risk of relapse and disease progression for an implant, and predicted uptake for an implant is relatively high.

Abstract
Importance Availability of new disease-modifying therapies (DMTs) and changes of therapeutic paradigms have led to a general improvement of multiple sclerosis (MS) prognosis in adults. It is still unclear whether this improvement also involves patients with pediatric-onset MS (POMS), whose early management is more challenging. Objective To evaluate changes in the prognosis of POMS over time in association with changes in therapeutic and managing standards. Design, Setting, and Participants Retrospective, multicenter, observational study. Data were extracted and collected in May 2019 from the Italian MS Registry, a digital database including more than 59 000 patients. Inclusion criteria were MS onset before age 18 years, diagnosis before January 2014, and disease duration of at least 3 years. Exclusion criteria were primary progressive MS, Expanded Disability Status Scale (EDSS) score of at least 8 one year after onset, unavailability of diagnosis date, and less than 2 EDSS score evaluations. Eligible patients were 4704 patients with POMS. According to these criteria, we enrolled 3198 patients, excluding 1506. Exposures We compared time to reach disability milestones by epoch of MS diagnosis (<1993, 1993-1999, 2000-2006, and 2007-2013), adjusting for possible confounders linked to EDSS evaluations and clinical disease activity. We then analyzed the difference among the 4 diagnosis epochs regarding demographic characteristics, clinical disease activity at onset, and DMTs management. Main Outcomes and Measures Disability milestones were EDSS score 4.0 and 6.0, confirmed in the following clinical evaluation and in the last available visit. Results We enrolled 3198 patients with POMS (mean age at onset, 15.2 years; 69% female; median time to diagnosis, 3.2 years; annualized relapse rate in first 1 and 3 years, 1.3 and 0.6, respectively), with a mean (SD) follow-up of 21.8 (11.7) years. Median survival times to reach EDSS score of 4.0 and 6.0 were 31.7 and 40.5 years. The cumulative risk of reaching disability milestones gradually decreased over time, both for EDSS score of 4.0 (hazard ratio [HR], 0.70; 95% CI, 0.58-0.83 in 1993-1999; HR, 0.48; 95% CI, 0.38-0.60 in 2000-2006; and HR, 0.44; 95% CI, 0.32-0.59 in 2007-2013) and 6.0 (HR, 0.72; 95% CI, 0.57-0.90; HR, 0.44; 95% CI, 0.33-0.60; and HR, 0.30; 0.20-0.46). In later diagnosis epochs, a greater number of patients with POMS were treated with DMTs, especially high-potency drugs, that were given earlier and for a longer period. Demographic characteristics and clinical disease activity at onset did not change significantly over time. Conclusions and Relevance In POMS, the risk of persistent disability has been reduced by 50% to 70% in recent diagnosis epochs, probably owing to improvement in therapeutic and managing standards.

Low serum neurofilament light chain values identify optimal responders to dimethyl fumarate in multiple sclerosis treatment. Sci Rep 2021; 11:9299.

Abstract
Serum neurofilament light chains (sNfL) are biomarkers of disease activity in multiple sclerosis (MS), but their value to predict response to treatment, and their association with patient immunological profile, need to be further explored. We studied 80 relapsing–remitting MS patients initiating dimethyl fumarate (DMF) treatment. sNfL levels were explored at baseline and at 3, 6 and 12 months by single molecule array. Blood lymphocyte subsets were measured at baseline and at 6 months by flow cytometry. Patients were followed a year and classified as NEDA (no evidence of disease activity) or ODA (ongoing disease activity). NEDA patients had lower sNfL levels at baseline (p = 0.0001), and after three (p = 0.004) and six (p = 0.03) months of DMF treatment. Consequently, low baseline sNfL values (≤ 12 pg/ml) increased the probability of NEDA (OR 5.8; CI 1.82–15.6; p = 0.002, after correcting by disease activity in the previous year), and associated with significant reductions of central memory CD4+ T lymphocytes, interferon-gamma+ CD8+ T lymphocytes, Natural Killer T cells, and memory B cells upon DMF treatment, being the highest differences in memory B cells (p < 0.0001). This shows that low baseline sNfL values identify MS patients with higher probability of optimal response to DMF and of a reduction in effector immune cells.

Bolton C. An evaluation of the recognised systemic inflammatory biomarkers of chronic sub-optimal inflammation provides evidence for inflammageing (IFA) during multiple sclerosis (MS). Immun Ageing 2021; 18:18. [PMID: 33853634 PMCID: PMC8045202 DOI: 10.1186/s12979-021-00225-0] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2020] [Accepted: 03/12/2021] [Indexed: 01/11/2023]
Abstract
The pathogenesis of the human demyelinating disorder multiple sclerosis (MS) involves the loss of immune tolerance to self-neuroantigens. A deterioration in immune tolerance is linked to inherent immune ageing, or immunosenescence (ISC). Previous work by the author has confirmed the presence of ISC during MS. Moreover, evidence verified a prematurely aged immune system that may change the frequency and profile of MS through an altered decline in immune tolerance. Immune ageing is closely linked to a chronic systemic sub-optimal inflammation, termed inflammageing (IFA), which disrupts the efficiency of immune tolerance by varying the dynamics of ISC that includes accelerated changes to the immune system over time. Therefore, a shifting deterioration in immunological tolerance may evolve during MS through adversely-scheduled effects of IFA on ISC. However, there is, to date, no collective proof of ongoing IFA during MS. The Review addresses the constraint and provides a systematic critique of compelling evidence, through appraisal of IFA-related biomarker studies, to support the occurrence of a sub-optimal inflammation during MS. The findings justify further work to unequivocally demonstrate IFA in MS and provide additional insight into the complex pathology and developing epidemiology of the disease.

Abstract
This article will review current treatment options for multiple sclerosis (MS) while keeping our primary focus on alemtuzumab, as it is now approved in more than 65 countries. From a pathophysiological point of view, MS is a disabling disease impacting a patient's life both physically and mentally, leading to devastating social and economic impact. This review will elaborate on alemtuzumab's role in treating relapsing-remitting MS (RRMS) by comparing its efficacy, side effects, and monitoring with other disease-modifying therapies (DMTs) available in the market. It is a point of great concern not only for physicians but also for neurologists, nephrologists, endocrinologists, dermatologists, and oncologists when encountering long-term effects of alemtuzumab in the life of treated MS patients. We hope that our review will not only benefit treating faculties but also those who are suffering from this devastating disease.

Visser LA, De Mul M, Redekop WK. Innovative Medical Technology and the Treatment Decision-Making Process in Multiple Sclerosis: A Focus Group Study to Examine Patient Perspectives. Patient Prefer Adherence 2021; 15:927-937. [PMID: 33994779 PMCID: PMC8114356 DOI: 10.2147/ppa.s306132] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/10/2021] [Accepted: 03/25/2021] [Indexed: 11/23/2022] Open
Abstract
BACKGROUND Disease-modifying therapies are given to people with multiple sclerosis (MS) to reduce disease progression and relapse frequency. Current modes of administration include oral, injectable and infusion therapy and the treatment decision-making process is complex. A novel mode of treatment administration, an implantable device, is currently under development, yet patient attitudes about the device are unknown. The aim of this study was 1) to understand the treatment decision-making process from the patient perspective and 2) to explore the possible acceptance of an implant to treat MS. METHODS Focus groups with people with MS were conducted in the Netherlands. Three topics were addressed: the treatment decision-making process, the current treatment landscape, and attitudes about the implantable device. All focus groups were recorded and transcribed and data were analyzed by raw data coding and creating themes. An online survey was conducted in the Netherlands to quantify interest in an implant. RESULTS Two focus group sessions were held (n=16 participants) and n=93 persons filled out the survey. The main theme that emerged was the constant uncertainty persons with MS face throughout their disease course and during treatment decisions (when to start, stop, continue or switch treatment). Patients were generally positive towards the implant but felt that efficacy and safety should be guaranteed. CONCLUSION People with MS want some form of control over their disease and treatment course. New medical technologies, such as an implant, may enhance the treatment landscape and with caution we postulate that it may be accepted by patients as a new mode of administration, though further research is needed. For medical technologies to be successful, patients should be engaged early on in the design process.

Souza KM, Diniz IM, de Lemos LLP, Junior NGR, Zuppo IDF, Teodoro JA, Acurcio FDA, Atallah ÁN, Júnior AAG. Effectiveness of first-line treatment for relapsing-remitting multiple sclerosis in Brazil: A 16-year non-concurrent cohort study. PLoS One 2020; 15:e0238476. [PMID: 32877451 PMCID: PMC7467258 DOI: 10.1371/journal.pone.0238476] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2020] [Accepted: 08/17/2020] [Indexed: 01/25/2023] Open
Abstract
BACKGROUND Relapsing-remitting multiple sclerosis (RRMM) is a chronic, progressive, inflammatory and immune-mediated disease that affects the central nervous system and is characterized by episodes of neurological dysfunction followed by a period of remission. The pharmacological strategy aims to delay the progression of the disease and prevent relapse. Interferon beta and glatiramer are commonly used in the Brazilian public health system and are available to patients who meet the guideline criteria. The scenario of multiple treatments available and in development brings the need for discussion and evaluation of the technologies already available before the incorporation of new drugs. This study analyses the effectiveness of first-line treatment of RRMS measured by real-world evidence data, from the Brazilian National Health System (SUS). METHODS AND FINDINGS We conducted a non-concurrent national cohort between 2000 and 2015. The study population consisted of 22,722 patients with RRMS using one of the following first-line drugs of interest: glatiramer or one of three presentations of interferon beta. Kaplan-Meier analysis was used to estimate the time to treatment failure. A univariate and multivariate Cox proportional hazard model was used to evaluate factors associated with treatment failure. In addition, patients were propensity score-matched (1:1) in six groups of comparative first-line treatments to evaluate the effectiveness among them. The analysis indicated a higher risk of treatment failure in female patients (HR = 1.08; P = 0,01), those with comorbidities at baseline (HR = 1.20; P<0,0001), in patients who developed comorbidities after starting treatment (i.e., rheumatoid arthritis-HR = 1.65; P<0,0001), those exclusive SUS patients (HR = 1.31; P<0,0001) and among patients using intramuscular interferon beta (IM βINF-1a) (28% to 60% compared to the other three treatments; P<0,0001). Lower risk of treatment failure was found among patients treated with glatiramer. CONCLUSIONS This retrospective cohort suggests that glatiramer is associated with greater effectiveness compared to the three presentations of interferon beta. When evaluating beta interferons, the results suggest that the intramuscular presentation is not effective in the treatment of multiple sclerosis.

Dimethyl fumarate vs Teriflunomide: an Italian time-to-event data analysis. J Neurol 2020; 267:3008-3020. [PMID: 32506391 DOI: 10.1007/s00415-020-09959-1] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2020] [Revised: 05/23/2020] [Accepted: 05/28/2020] [Indexed: 10/24/2022]
Abstract
BACKGROUND The introduction of oral disease-modifying therapies (DMTs) for relapsing-remitting multiple sclerosis (RRMS) changed algorithms of RRMS treatment. OBJECTIVES To compare the effectiveness of treatment with dimethyl fumarate (DMF) and teriflunomide (TRF) in a large multicentre Italian cohort of RRMS patients. MATERIALS AND METHODS Patients with RRMS who received treatment with DMF and TRF between January 1st, 2012 and December 31st, 2018 from twelve MS centers were identified. The events investigated were "time-to-first-relapse", "time-to-Magnetic-Resonance-Imaging (MRI)-activity" and "time-to-disability-progression". RESULTS 1445 patients were enrolled (1039 on DMF, 406 on TRF) and followed for a median of 34 months. Patients on TRF were older (43.5 ± 8.6 vs 38.8 ± 9.2 years), with a predominance of men and higher level of disability (p < 0.001 for all). Patients on DMF had a higher number of relapses and radiological activity (p < .05) at baseline. Time-varying Cox-model for the event "time-to-first relapse" revealed that no differences were found between the two groups in the first 38 months of treatment (HRt < 38DMF = 0.73, CI = 0.52 to 1.03, p = 0.079). When the time-on-therapy exceeds 38 months patients on DMF had an approximately 0.3 times lower relapse hazard risk than those who took TRF (HRt>38DMF = 3.83, CI = 1.11 to 13.23, p = 0.033). Both DMTs controlled similarly MRI activity and disability progression. CONCLUSIONS Patients on DMF had higher relapse-free survival time than TRF group after the first 38 months on therapy.

Regulatory B Cells Normalize CNS Myeloid Cell Content in a Mouse Model of Multiple Sclerosis and Promote Oligodendrogenesis and Remyelination. J Neurosci 2020; 40:5105-5115. [PMID: 32430295 DOI: 10.1523/jneurosci.2840-19.2020] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2019] [Revised: 04/03/2020] [Accepted: 05/13/2020] [Indexed: 01/13/2023] Open
Abstract
The unmet medical need of patients with multiple sclerosis (MS) is the inexorable loss of CNS myelin and latterly neurons leading to permanent neurologic disability. Solicitation of endogenous oligodendrocytes progenitor cells, the precursor of oligodendrocytes, to remyelinate axons may abort the onset of disability. In female mice with experimental autoimmune encephalomyelitis (EAE), a murine model of MS, adoptive transfer of IL-10+ regulatory B cells (Bregs) has been shown to reverse EAE by promoting the expansion of peripheral and CNS-infiltrating IL-10+ T cells. Here, we examined whether Bregs treatment and its bystander effect on regulatory T cells are associated with CNS repair as reflected by oligodendrogenesis and remyelination. We have found that transfusion of Bregs reverses established clinical EAE and that clinical improvement is associated with a significant increase in spinal cord remyelination as reflected by g-ratio analysis within the thoracic and lumbar spine. We further observed in the spinal cords of EAE Bregs-treated mice that CNS resident CD11b/CD45intLy6C- microglia, and infiltrating CD11b+/CD45high monocytes/macrophages content reverts to normal and polarize to a M2-like CD206+ phenotype. Concurrently, there was a substantial increase in neo-oligodendrogenesis as manifest by an increase in CD45-/low CNS cells expressing A2B5, an early marker in oligodendrocytes progenitor cell differentiation as well as GalC+/O1+ premyelinating and myelin basic protein+/myelin oligodendrocyte glycoprotein+ mature oligodendrocytes with reciprocal downregulation of paired related homeobox protein 1. These results demonstrate that the clinical benefit of Bregs is associated with normalization of CNS immune milieu and concurrent activation of oligodendrocyte progenitor cells with subsequent remyelination.SIGNIFICANCE STATEMENT In multiple sclerosis patients, demyelination progresses with aging and disease course, leading to irreversible disability. In this study, we have discovered, using a mouse model of multiple sclerosis, that the transfusion of autologous regulatory B cells (Bregs) is able to ameliorate, cure, and sustain the durable remission of the disease. We show that the adoptive transfer of Bregs dramatically decreased the frequency of myeloid-derived cells, both infiltrating monocytes/macrophages and resident microglia, and converted their phenotype to an immunosuppressive-like phenotype. Moreover, we showed that CNS oligodendrocyte progenitor cells are activated following Bregs treatment and differentiate into myelinating oligodendrocytes, which results in neo-oligodendrogenesis and remyelination of spinal cords.

Abstract
The modern era of multiple sclerosis (MS) treatment began 25 years ago, with the approval of IFNβ and glatiramer acetate for the treatment of relapsing-remitting MS. Ten years later, the first monoclonal antibody, natalizumab, was approved, followed by a third important landmark with the introduction of oral medications, initially fingolimod and then teriflunomide, dimethyl fumarate and cladribine. Concomitantly, new monoclonal antibodies (alemtuzumab and ocrelizumab) have been developed and approved. The modern era of MS therapy reached primary progressive MS in 2018, with the approval of ocrelizumab. We have also learned the importance of starting treatment early and the importance of clinical and MRI monitoring to assess treatment response and safety. Treatment decisions should account for disease phenotype, prognostic factors, comorbidities, the desire for pregnancy and the patient's preferences in terms of acceptable risk. The development of treatment for MS during the past 25 years is a fantastic success of translational medicine.

Mult Scler Relat Disord 2020; 40:101971. [PMID: 32062444 DOI: 10.1016/j.msard.2020.101971] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2019] [Revised: 12/17/2019] [Accepted: 01/27/2020] [Indexed: 11/16/2022]
Abstract
BACKGROUND Modified-release 4-aminopyridine (fampridine-MR) is used in the symptomatic treatment of walking disability in patients with multiple sclerosis (MS). Its potential for use in other MS symptoms remains unproven and its mode of action in this context is uncertain. Interest is growing in the use of upper limb outcome measures in clinical trials in patients with Multiple Sclerosis, particularly in advanced or progressive disease. This study tests the following hypotheses: (1) Fampridine-MR improves upper limb function in patients with MS and upper limb impairment. (2) Treatment with fampridine-MR is associated with measurable alterations in objective electrophysiological parameters (evoked potentials and transcranial magnetic stimulation (TMS)) which may predict response to drug treatment. METHODS Study population: patients with MS of any disease subtype, duration and severity who have symptomatic impairment of one or both upper limbs. A healthy control group was included for validation of clinical and electrophysiological measures. Study design: randomised double blind placebo-controlled trial. Treatment details: participants allocated to either fampridine-MR 10 mg bd or placebo of identical appearance for 8 weeks. Primary outcome: performance on 9-hole peg test (9HPT) after 4 weeks. Secondary outcomes: persistence of effect on 9HPT; grip strength; visual acuity and contrast sensitivity; modified fatigue impact scale score; sensory discrimination capacity; visual, somatosensory and motor evoked potentials; resting motor threshold; paired-pulse TMS; peripheral nerve conduction studies. RESULTS 40 patients with MS (60% female, median age 52, median disease duration 13.5 years, median EDSS 6.0) were enrolled. Treatment with fampridine-MR was not associated with any change in upper limb function as measured by the clinical primary or secondary outcomes. Treatment with fampridine-MR was also not associated with any difference in electrophysiological measures of upper limb function. This held true after adjustment for hand dominance, disease duration and severity. Four patients withdrew from the trial because of lack of efficacy or side-effects; all were in the placebo arm. Three patients were admitted to hospital during the study period; one with MS exacerbation (placebo group), one with syncope (drug group) and one with UTI (drug group); otherwise there were no serious adverse events. CONCLUSION Treatment with fampridine-MR was well-tolerated but did not produce clinical benefit in terms of upper limb function, vision or fatigue, nor was there any measurable effect on objective electrophysiological parameters.

Abstract
BACKGROUND Considering the multiple treatments approved for multiple sclerosis (MS) by the Food and Drug Administration (FDA) and European Medicines Agency (EMA), determining a treatment strategy for patients with clinically isolated syndrome (CIS) and relapsing-remitting MS (RRMS) can be challenging. To date, an overview of the needs and preferences of patients at each treatment decision-making moment is lacking. Therefore, the aim of this systematic review is to examine the existing literature about the needs and preferences of patients with CIS and RRMS when making treatment decisions. METHODS A systematic search was done using Embase, Medline, PsychINFO, Web of Science and Google Scholar. Eligibility criteria included whether the article described a study of adults with CIS/RRMS and reported patient needs or preferences regarding first-line disease modifying treatment (DMT) decisions. Publications were categorized by treatment decision: initiation of first DMT (D1), DMT adherence/discontinuation (D2a/D2b), and switch to a second DMT (D3). A separate category was created for stated preference studies such as discrete choice experiment methods to examine the relative importance of different treatment attributes. Publications were compared to identify key factors. RESULTS The search yielded 2789 articles after removal of duplicates and 434 full-text publications were reviewed for eligibility. Twenty-four articles fulfilled all criteria: n = 5 (D1), n = 12 (D2a), n = 13 (D2b), and n = 3 (D3); six articles studied more than one treatment decision. The need for social support is important during D1. The most commonly reported reasons for adherence/discontinuation/switch included forgetfulness, side-effects, and injection-related reasons. Eight articles described preference studies; the most important DMT attributes were efficacy, mode and frequency of administration, and side-effect profile. CONCLUSIONS Understanding the needs and preferences of CIS/RRMS patients regarding DMT attributes and non-treatment related attributes are important to improve treatment decision-making and reduce non-adherence. Studies are needed to understand patient preferences upon treatment initiation. Furthermore, preference studies should include attributes based on the patient perspective.

Abstract
Interferon beta (IFNβ) was the first disease-modifying therapy available to treat multiple sclerosis (MS), providing patients with a treatment that resulted in reduced relapse rates and delays in the onset of disability. Four IFNβ drugs are currently approved to treat relapsing forms of MS: subcutaneous (SC) IFNβ-1b, SC IFNβ-1a, intramuscular IFNβ-1a, and, most recently, SC peginterferon beta-1a. Peginterferon beta-1a has an extended half-life and requires less frequent administration than other available treatments (once every 2 weeks vs every other day, 3 times per week, or weekly). Large randomized controlled clinical trials have confirmed the efficacy of interferons for the treatment of relapsing MS. The most frequent adverse events in patients receiving IFNs include injection site reactions and flu-like symptoms. Patient education and mitigation strategies are key to managing these adverse events and supporting therapy adherence. With fewer injections needed, peginterferon beta-1a is associated with less frequent discomfort, which may translate to improved adherence, a major factor in treatment efficacy. Because the available interferon therapies differ in administration route and frequency of injection, switching among these therapies may be a viable option for patients who experience issues with tolerability. Although a variety of disease-modifying therapies are now available to treat relapsing MS, the efficacy and long-term safety profile of interferons make them an important first-line option for treatment.

Abstract
The expanding therapeutic arsenal in multiple sclerosis (MS) has allowed for more effective and personalized treatment, but the choice and management of disease-modifying therapies (DMTs) is becoming increasingly complex. In this context, experts from the Brazilian Committee on Treatment and Research in Multiple Sclerosis and the Neuroimmunology Scientific Department of the Brazilian Academy of Neurology have convened to establish this Brazilian Consensus for the Treatment of MS, based on their understanding that neurologists should be able to prescribe MS DMTs according to what is better for each patient, based on up-to-date evidence and practice. We herein propose practical recommendations for the treatment of MS, with the main focus on the choice and management of DMTs, as well as present a review of the scientific rationale supporting therapeutic strategies in MS.

Abstract
Dimethyl fumarate (DMF) is an oral disease-modifying therapy approved for management of relapsing-remitting multiple sclerosis patients. Results from phase 3 clinical trials (DEFINE, CONFIRM) and follow-up study (ENDORSE) have provided good evidence for its efficacy and safety profile. Patient-reported outcomes (PROs) assessment revealed stabilization or boost in health-related quality of life and work productivity of patients treated with DMF compared to placebo reflecting a higher patient satisfaction to therapy. Being an oral agent with relatively favorable risk versus benefit profile DMF is commonly prescribed first-line agent. However, literature suggests that intolerance to side effects, especially gastrointestinal adverse effects and flushing is one of the major causes to compromised therapeutic compliance. An increase in the real-world incidence of progressive multifocal leukoencephalopathy and liver abnormality cases is also concerning. Several prevention and mitigation strategies like patient counseling, dose up-titration, pretreatment with aspirin, use of symptomatic therapy and frequent blood monitoring have demonstrated to be effective in tackling these adverse effects and promoting adherence to DMF. In this article, we review the efficacy, safety, PROs and patient adhere data, along with various measures to manage adverse events and promote compliance.

Abstract
Multiple sclerosis (MS) is a chronic neurologic disease and the most common cause of nontraumatic disability in young adults in the United States. It strikes adults in the prime of life and can gradually diminish physical and mental function, affect relationships, employment, financial capacity, and independence. Neurologic symptoms fluctuate in a pattern of remissions and exacerbations for the majority of those with MS. A multidisciplinary treatment approach is essential. There are a wide number of medications that can be used. Treating the disease at an early stage within the first 5 years of clinical symptom onset is optimal. Home healthcare clinicians can use assessment tools to evaluate disease progression, teach the patient and family how to live with the disorder, and monitor the patient for medication side effects.

Abstract
Background: The aim of the study was to evaluate the achievement of ‘no evidence of
disease activity’ (NEDA) over a 12-month period in a large multicenter
population with relapsing remitting multiple sclerosis (RRMS) treated with
delayed-release dimethyl fumarate (DMF) and teriflunomide (TRF) using a
propensity-score adjustment. Methods: A time-to-event method was used to determine the percentages of patients with
RRMS (pwRRMS) in both groups achieving NEDA 3 (no relapses, no 12-week
confirmed disability progression, and no new T2/gadolinium-enhancing brain
lesions). We described the safety profile of the investigated drugs. Results: Of the 587 pwRRMS treated with DMF and the 316 pwRRMS treated with TRF, 468
pwRRMS were successfully paired by propensity score: 234 on DMF and 234 on
TRF. The percentages of pwRRMS who achieved NEDA 3 were 80.3% in the DMF
group and 77.2% in the TRF group. Serious adverse events occurred in four
(1.9%) pwRRMS on DMF and in three (1.3%) pwRRMS on TRF. Conclusions: DMF and TRF significantly impacted RRMS disease activity in our study.
Serious safety concerns were recorded in less than 2% of the studied
population.

Abstract
INTRODUCTION Multiple sclerosis (MS) is a chronic and disabling immune-mediated disease of the central nervous system. Beta-interferons are the first approved and still the most widely used first-line disease-modifying treatment in MS. AREAS COVERED Here we focus on recent developments in pharmacology and delivery systems of beta-interferons, and discuss their place within current state of the art therapeutic approaches. We briefly review the clinical trials for classical and PEGylated formulations, emphasizing effectiveness, safety concerns, and tolerability. The mechanisms of action of IFN-β in view of MS pathogenesis are also debated EXPERT OPINION Though only modestly efficient in reducing the annualized relapse rate, beta-interferons remain a valid first-line option due to their good long-term safety profile and cost-efficacy. Moreover, they are endogenous class II cytokines essential for mounting an effective antiviral response, and they may interact with putative MS triggering factors such as Epstein-Barr virus infection and human endogenous retroviruses. Recent improvements in formulations, delivery devices and drug regimens tackle the tolerability and adherence issues frequently seen with these drugs, and scientific advances may offer means for a better selection of patients. Although a well-established immunomodulatory treatment, beta-interferons have not said their last word in the management of MS.

Abstract
In Brazil, inclusion and exclusion of health technologies within the Unified Health System (SUS) is the responsibility of the National Committee for Health Technology Incorporation (CONITEC). A recent Cochrane systematic review demonstrated that intramuscular interferon beta 1a (IFN-β-1a-IM) was inferior to the other beta interferons (IFN-βs) for multiple sclerosis (MS). As a result, CONITEC commissioned an analysis to review possible disinvestment within SUS. The objective of this paper is to describe the disinvestment process for IFN-β-1a-IM in Brazil. The first assessment comprised a literature review and mixed treatment comparison meta-analysis. The outcome of interest was the proportion of relapse-free patients in 2 years. This analysis confirmed the inferiority of IFN-β-1a-IM. Following this, CONITEC recommended disinvestment, with the decision sent for public consultation. More than 3000 contributions were made on CONITEC's webpage, most of them against the preliminary decision. As a result, CONITEC commissioned a study to assess the effectiveness of IFN-β-1a-IM among Brazilian patients in routine clinical care. The second assessment involved an 11-year follow-up of a non-concurrent cohort of 12,154 MS patients developed by deterministic-probabilistic linkage of SUS administrative databases. The real-world assessment further demonstrated that IFN-β-1a-IM users had a statistically higher risk of treatment failure, defined as treatment switching or relapse treatment or death, with the assessment showing that IFN-β-1a-IM was inferior to the other IFN-βs and to glatiramer acetate in both direct and indirect analysis. In the drug ranking with 40,000 simulations, IFN-β-1a-IM was the worst option, with a success rate of only 152/40,000. Following this, CONITEC decided to exclude the intramuscular presentation of IFN-β from the current MS treatment guidelines, giving patients who are currently on this treatment the option of continuing until treatment failure. In conclusion, we believe this is the first example of this new disinvestment process in action, providing an exemplar for other treatments in Brazil as well as other countries.

Abstract
BACKGROUND Multiple sclerosis (MS) is an autoimmune disease, in which the insulating covers of nerve cells in the brain and spinal cord are demyelinated. This study was conducted to compare the efficacy of alemtuzumab and natalizumab in the treatment of different stages of MS patients. METHODS A total of 585 patients diagnosed with MS and hospitalized were included and analyzed after which they were divided into the primary progressive MS A and B groups, the relapsing-remitting MS (RRMS) C and D groups, and the secondary progressive MS E and F groups. Patients in A, C, and E groups were administered alemtuzumab while those in B, D, and F groups were administered natalizumab for the treatment. The expanded disability status scale (EDSS) scores and the EDSS difference were calculated before and after treatment. The number of head magnetic resonance imaging enhanced lesions in the patients, recurrence time and recurrence rate were measured before and after treatment. RESULTS The EDSS score of the RRMS group was significantly lower than that of the primary progressive MS group and the secondary progressive MS group. After 12 months of treatment, the EDSS score of RRMS patients treated with natalizumab was significantly lower compared with the patients with alemtuzumab, and the difference before and after treatment was significantly higher than alemtuzumab. The recurrence rate of the RRMS-D group was significantly lower than the RRMS-C group. After 12 months of treatment, compared with the RRMS-C group, a significant reduction was observed in the number of head magnetic resonance imaging enhanced lesions and longer recurrence time in the RRMS-D group. CONCLUSION The efficacy of natalizumab was better than alemtuzumab in the treatment of patients in the RRMS group, while there was no significant difference among other stages of MS patients, which provided the theoretical basis and clinical guidance for the treatment of different stages of MS.

Abstract
The availability of multiple disease-modifying medications with regulatory approval to treat multiple sclerosis illustrates the substantial progress made in therapy of the disease. However, all are only partially effective in preventing inflammatory tissue damage in the central nervous system and none directly promotes repair. Cell-based therapies, including immunoablation followed by autologous haematopoietic stem cell transplantation, mesenchymal and related stem cell transplantation, pharmacologic manipulation of endogenous stem cells to enhance their reparative capabilities, and transplantation of oligodendrocyte progenitor cells, have generated substantial interest as novel therapeutic strategies for immune modulation, neuroprotection, or repair of the damaged central nervous system in multiple sclerosis. Each approach has potential advantages but also safety concerns and unresolved questions. Moreover, clinical trials of cell-based therapies present several unique methodological and ethical issues. We summarize here the status of cell-based therapies to treat multiple sclerosis and make consensus recommendations for future research and clinical trials.

Abstract
The treatment landscape for relapsing forms of multiple sclerosis (RMS) has expanded considerably over the last 10 years with the approval of multiple new disease-modifying therapies (DMTs), and others in late-stage clinical development. All DMTs for RMS are believed to reduce central nervous system immune-mediated inflammatory processes, which translate into demonstrable improvement in clinical and radiologic outcomes. However, some DMTs are associated with long-lasting effects on the immune system and/or serious adverse events, both of which may complicate the use of subsequent therapies. When customizing a treatment program, a benefit–risk assessment must consider multiple factors, including the efficacy of the DMT to reduce disease activity, the short- and long-term safety and immunologic profiles of each DMT, the criteria used to define switching treatment, and the risk tolerance of each patient. A comprehensive benefit–risk assessment can only be achieved by evaluating the immunologic, safety, and efficacy data for DMTs in the controlled clinical trial environment and the postmarketing clinical practice setting. This review is intended to help neurologists make informed decisions when treating RMS by summarizing the known data for each DMT and raising awareness of the multiple considerations involved in treating people with RMS throughout the entire course of their disease.

Abstract
Daclizumab (Zinbryta®; previously known as daclizumab high-yield process) is a therapeutic monoclonal antibody that has recently been approved for the treatment of relapsing forms of multiple sclerosis (MS) in adults. Daclizumab is a humanized IgG1 monoclonal antibody directed against CD25, the alpha subunit of the high-affinity interleukin-2 receptor. As demonstrated in the phase III DECIDE trial, once-monthly subcutaneous daclizumab was superior to once-weekly intramuscular interferon (IFN) β-1a in reducing the clinical relapse rate and radiological measures of disease in patients with relapsing-remitting MS. In addition, daclizumab has demonstrated efficacy in reducing disability progression and in improving health-related quality of life in patients with relapsing MS. Ongoing open-label clinical trials indicate that daclizumab's efficacy is maintained in the longer term (3 years or more). Daclizumab appears to be generally well tolerated, with adverse events of interest (including hepatic, infectious and cutaneous events) generally manageable with regular monitoring and/or standard therapies. The place of daclizumab in MS treatment remains to be fully determined. However, based on available evidence, daclizumab provides a useful alternative option to other currently available disease-modifying therapies in the treatment of relapsing MS.

Abstract
OBJECTIVE This study aimed to test the number needed to treat to benefit (NNTB) and to harm (NNTH), and the likelihood to be helped or harmed (LHH) when assessing benefits, risks, and benefit-risk ratios of disease-modifying treatments (DMTs) approved for relapsing-remitting multiple sclerosis (RRMS). METHODS In May 2016, we conducted a systematic review using the PubMed and Cochrane Central Register of Controlled Trials databases to identify phase III, randomized controlled trials with a duration of ≥2 years that assessed first-line (dimethyl fumarate [DMF], glatiramer acetate [GA], β-interferons [IFN], and teriflunomide) or second-line (alemtuzumab, fingolimod, and natalizumab) DMTs in patients with RRMS. Meta-analyses were performed to estimate relative risks (RRs) on annualized relapse rate (ARR), proportion of relapse-free patients (PPR-F), disability progression (PP-F-CDPS3M), and safety outcomes. NNTB and NNTH values were calculated applying RRs to control event rates. LHH was calculated as NNTH/NNTB ratio. RESULTS The lowest NNTBs on ARR, PPR-F, and PP-F-CDPS3M were found with IFN-β-1a-SC (NNTB 3, 95 % CI 2-4; NNTB 7, 95 % CI 4-18; NNTB 4, 95 % CI 3-7, respectively) and natalizumab (NNTB 2, 95 % CI 2-3; NNTB 4, 95 % CI 3-6; NNTB 9, 95 % CI 6-19, respectively). The lowest NNTH on adverse events leading to treatment discontinuation was found with IFN-β-1b (NNTH 14, 95 % 2-426) versus placebo; a protective effect was noted with alemtuzumab versus IFN-β-1a-SC (NNTB 22, 95 % 17-41). LHHs >1 were more frequent with IFN-β-1a-SC and natalizumab. CONCLUSIONS These metrics may be valuable for benefit-risk assessments, as they reflect baseline risks and are easily interpreted. Before making treatment decisions, clinicians must acknowledge that a higher RR reduction with drug A as compared with drug B (versus a common comparator in trial A and trial B, respectively) does not necessarily mean that the number of patients needed to be treated for one patient to encounter one aditional outcome of interest over a defined period of time is lower with drug A than with drug B. Overall, IFN-β-1a-SC and natalizumab seem to have the most favorable benefit-risk ratios among first- and second-line DMTs, respectively.

Abstract
Performing a therapeutic switch in MS is still a matter of debate. Objective of our study is to compare switching to another first-line therapy with switching to a second-line therapy in persons with relapsing-remitting multiple sclerosis (pwRRMS). A retrospective analysis of data prospectively collected was performed. PwRRMS experiencing on-treatment disease activity were included. No clinical relapse, no sustained disability progression by the Expanded Disability Status Scale (EDSS), and no radiological activity (new T2 and/or gadolinium-enhanced brain lesions) were used as indicators of no disease activity (NEDA 3). Time to reach the first relapse after switch and time to reach an EDSS of 4.0 were also evaluated. Ninety-one pwRRMS were enrolled. Forty-eight (52.7 %) were on lateral switch, and 43 (47.3 %) on escalation switch. At baseline, the two groups differed for T2 and T1 brain lesions number (higher in the escalation group, p < 0.005). The proportion of pwRRMS who were NEDA 3 after 24 months from the switch was similar in the two groups (20.8 % in lateral group and 18.6 % in escalation group). No difference in timing to reach the first relapse after switch and an EDSS of 4.0 were found. Therefore, in selected pwRRMS, lateral and escalation strategies showed similar efficacy in delaying MS progression.
