Habtemariam S. Anti-Inflammatory Therapeutic Mechanisms of Isothiocyanates: Insights from Sulforaphane. Biomedicines 2024; 12:1169. [PMID: 38927376 PMCID: PMC11200786 DOI: 10.3390/biomedicines12061169] [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: 04/23/2024] [Revised: 05/16/2024] [Accepted: 05/21/2024] [Indexed: 06/28/2024] Open
Abstract
Isothiocyanates (ITCs) belong to a group of natural products that possess a highly reactive electrophilic -N=C=S functional group. They are stored in plants as precursor molecules, glucosinolates, which are processed by the tyrosinase enzyme upon plant tissue damage to release ITCs, along with other products. Isolated from broccoli, sulforaphane is by far the most studied antioxidant ITC, acting primarily through the induction of a transcription factor, the nuclear factor erythroid 2-related factor 2 (Nrf2), which upregulates downstream antioxidant genes/proteins. Paradoxically, sulforaphane, as a pro-oxidant compound, can also increase the levels of reactive oxygen species, a mechanism which is attributed to its anticancer effect. Beyond highlighting the common pro-oxidant and antioxidant effects of sulforaphane, the present paper was designed to assess the diverse anti-inflammatory mechanisms reported to date using a variety of in vitro and in vivo experimental models. Sulforaphane downregulates the expression of pro-inflammatory cytokines, chemokines, adhesion molecules, cycloxyhenase-2, and inducible nitric oxide synthase. The signalling pathways of nuclear factor κB, activator protein 1, sirtuins 1, silent information regulator sirtuin 1 and 3, and microRNAs are among those affected by sulforaphane. These anti-inflammatory actions are sometimes due to direct action via interaction with the sulfhydryl structural moiety of cysteine residues in enzymes/proteins. The following are among the topics discussed in this paper: paradoxical signalling pathways such as the immunosuppressant or immunostimulant mechanisms; crosstalk between the oxidative and inflammatory pathways; and effects dependent on health and disease states.

Abstract
Aging is the progressive decline of body functions and a number of chronic conditions can lead to premature aging characterized by frailty, a diseased vasculature, osteoporosis, and muscle wasting. One of the major conditions associated with premature and accelerated aging is chronic kidney disease (CKD), which can also result in early vascular aging and the stiffening of the arteries. Premature vascular aging in CKD patients has been considered as a marker of prognosis of mortality and cardiovascular morbidity and therefore requires further attention. Oxidative stress, inflammation, advanced glycation end products, fructose, and an aberrant gut microbiota can contribute to the development of early aging in CKD patients. There are several key molecular pathways and molecules which play a role in aging and vascular aging including nuclear factor erythroid 2-related factor 2 (Nrf-2), AMP-activated protein kinase (AMPK), sirtuin 1 (SIRT1), and klotho. Potential therapeutic strategies can target these pathways. Future studies are needed to better understand the importance of premature aging and early vascular aging and to develop therapeutic alternatives for these conditions.

J Neuroimmunol 2023; 383:578178. [PMID: 37672841 DOI: 10.1016/j.jneuroim.2023.578178] [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: 06/28/2023] [Revised: 08/13/2023] [Accepted: 08/17/2023] [Indexed: 09/08/2023]
Abstract
OBJECTIVES To report pregnancy outcomes among multiple sclerosis (MS) patients treated with disease-modifying therapies (DMTs). METHODS We performed a retrospective chart review of articles published from June 1996 to May 2023. Additional information was acquired from the drug registries of individual pharmaceutical companies. A comparison was also made with pregnancy data of the general population using the World Health Organization database. Summary analysis was achieved using R statistical software (v3.6), and the overall prevalence of outcomes was estimated using a random effects model. RESULTS A meta-analysis of 44 studies was conducted. Dimethyl fumarate had the highest prevalence of premature births at 0.6667% (SD:0.5236-0.7845). The highest rates of stillbirths and infant deaths (perinatal and neonatal) were observed with interferons at 0.004% (SD:0.001-0.010) and 0.009% (SD:0.005-0.0015), respectively. Cladribine had the majority of ectopic pregnancies (0.0234%, SD:0.0041-1217), while natalizumab had the highest prevalence of spontaneous abortions (0.1177%, SD:0.0931-0.1477) and live birth defects (0.0755%, SD:0.0643-0.0943).None of the outcomes were significantly different from those of the general population (p > 0.05), except ectopic pregnancy and spontaneous abortion (p < 0.001), where the odds were 0.665 (0.061-0.886) and 0.537(0.003-0.786), respectively. The pooled prevalence of MS relapses was 221% for a single episode (SD:0.001-0.714), 0.075% for more than one episode (SD:0.006-0.167), and 0.141% for at least one episode requiring steroids (SD:0.073-0.206) none of these reached clinical significance. CONCLUSION Existing research suggests that DMT use in MS patients during pregnancy is generally considered safe. This study supports their utilization on a case-by-case basis. However, further primary research on this topic with clinical trials is warranted.

Abstract
INTRODUCTION The emergence of several therapeutic options in multiple sclerosis (MS), which significantly modify the immune system functioning, has led to the need for the consideration of additional factors, such as risk of infections, in the decision-making process. The aim of these consensus recommendations was to discuss and perform a practical guide to Latin American neurologists on the risk of infections at diagnosis, follow-up and prior to initiation of DMDs. METHODS A panel of Latin American neurologists, experts in demyelinating diseases and dedicated to management and care of MS patients, gathered during 2021 and 2022 to make consensus recommendations on the risk of infections in PwMS treated with DMDs in Latin America. The RAND/UCLA methodology was developed to synthesize the scientific evidence and expert opinions on health care topics and was used for reaching a formal agreement. RESULTS Recommendations were established based on relevant published evidence and expert opinion, focusing on: 1- baseline infection disease and vaccination status; 2- opportunistic infections; 3- progressive multifocal leukoencephalopathy; 4- genitourinary system infections; 5- respiratory tract infections; 6- digestive system infections, 7-others local infections and 8- COVID-19. CONCLUSION The recommendations of this consensus seek to optimize the care, management and treatment of PwMS in Latin America. The standardized evidence-based care of pwMS infections will allow better outcomes.

Hepatobiliary Adverse Reactions during Treatment with Cladribine: Analysis of Data from the European Spontaneous Reporting System. Pharmaceuticals (Basel) 2023; 16:1071. [PMID: 37630986 PMCID: PMC10459297 DOI: 10.3390/ph16081071] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2023] [Revised: 07/23/2023] [Accepted: 07/24/2023] [Indexed: 08/27/2023] Open
Abstract
BACKGROUND Cladribine belongs to the group of disease-modifying therapies (DMTs) used to treat multiple sclerosis (MS). According to the highlights of a meeting held by the Pharmacovigilance Risk Assessment Committee (PRAC) on 14 January 2022, cladribine may be associated with the occurrence of liver injury, and thus liver function monitoring is recommended. OBJECTIVES AND METHODS Using data from the European spontaneous reporting database (EudraVigilance-EV), we aimed to describe the main characteristics of Individual Case Safety Reports (ICSRs) reporting cases of hepatobiliary disorders related to cladribine. The reporting odds ratio (ROR) was calculated to provide the probability of reporting hepatobiliary ICSRs among DMTs used to treat MS. RESULTS Overall, 118 ICSRs described the occurrence of cladribine-induced hepatobiliary ADRs. The majority of the ICSRs reported ADRs that were classified as serious (93%), and the outcome was mostly reported as "unknown" (50.8%). The most reported hepatobiliary disorders were drug-induced liver injury, abnormal hepatic function, ALT increases, liver disorders, hepatic failure, jaundice, lymphocyte count decreases, hepatotoxicity and hypertransaminasemia. The majority of cladribine-induced hepatic ADRs occurred in female patients belonging to the age group of 18-65 years. CONCLUSION Considering the seriousness of cladribine-induced hepatic ADRs, a close monitoring of patients receiving this drug is highly recommended. In this context, further pharmacovigilance studies evaluating the hepatic safety profile of cladribine are strongly needed.

Clinical use of dimethyl fumarate in multiple sclerosis treatment: an update to include China, using a modified Delphi method. Ther Adv Neurol Disord 2023; 16:17562864231180734. [PMID: 37465201 PMCID: PMC10350766 DOI: 10.1177/17562864231180734] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2022] [Accepted: 05/20/2023] [Indexed: 07/20/2023] Open
Abstract
Dimethyl fumarate (DMF) is a widely used oral disease-modifying therapy for multiple sclerosis (MS). Its efficacy and safety profiles are supported by over a decade of experience. Differences exist between Asia and Europe/United States in the prevalence and characteristics of MS; most data for DMF are derived from populations outside Asia. DMF was recently (2021) approved for use in China. The objectives of this review were to evaluate the evidence for DMF's profile, to provide an update to healthcare providers on current knowledge surrounding its use and to assess the relevance of existing data to use in China. This study used a modified Delphi method based on the insights of a scientific Steering Committee (SC), with a structured literature review conducted to assess the data of DMF. The literature review covered all papers in English (from 01 January 2011 to 21 February 2022) that include 'dimethyl fumarate' and 'multiple sclerosis', and their MeSH terms, on PubMed, supplemented by EMBASE and Citeline searches. Papers were categorized by topic and assessed for relevance and quality, before being used to formulate statements summarizing the literature on each subject. SC members voted on/revised statements, requiring ⩾80% agreement and ⩽10% disagreement for inclusion. Statements not reaching this level were discussed further until agreement was reached or until there was agreement to remove the statement. A total of 1030 papers were retrieved and used to formulate the statements and evidence summaries considered by the SC members. A total of 45 statements were agreed by the SC members. The findings support the positive efficacy and safety profile of DMF in treating patients with MS. Limited Chinese patient data are an ongoing consideration; however, based on current evidence, the statements are considered applicable to both the global and Chinese populations. DMF is a valuable addition to address unmet MS treatment needs in China. Registration: Not applicable.

Abstract
Alzheimer's disease (AD), the leading cause of dementia, is a growing health issue with very limited treatment options. To meet the need for novel therapeutics, existing drugs with additional preferred pharmacological profiles could be recruited. This strategy is known as 'drug repurposing'. Here, we describe dimethyl fumarate (DMF), a drug approved to treat multiple sclerosis (MS), to be tested as a candidate for other brain diseases. We used an APP-transgenic model (APPtg) of senile β-amyloidosis mice to further investigate the potential of DMF as a novel AD therapeutic. We treated male and female APPtg mice through drinking water at late stages of β-amyloid (Aβ) deposition. We found that DMF treatment did not result in modulating effects on Aβ deposition at this stage. Interestingly, we found that glutathione-modified DMF interacts with the ATP-binding cassette transporter ABCC1, an important gatekeeper at the blood-brain and blood-plexus barriers and a key player for Aβ export from the brain. Our findings suggest that ABCC1 prevents the effects of DMF, which makes DMF unsuitable as a novel therapeutic drug against AD. The discovered effects of ABCC1 also have implications for DMF treatment of multiple sclerosis.

Real-life outcomes for oral disease-modifying treatments of relapsing-remitting multiple sclerosis patients: Adherence and adverse event profiles from Marmara University. Turk J Med Sci 2023; 53:771-779. [PMID: 37476900 PMCID: PMC10388038 DOI: 10.55730/1300-0144.5640] [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: 01/17/2022] [Accepted: 02/01/2023] [Indexed: 07/22/2023] Open
Abstract
BACKGROUND Disease-modifying treatments (DMT) are used to prevent future relapses and disability. High long-term adherence to treatment is important to achieve disease control. This study aims to investigate and compare adherence, adverse event (AE) profiles, and frequencies, main reasons for treatment discontinuation under Teriflunomide (TERI), Dimethyl Fumarate (DMF), and Fingolimod (FNG) for relapsing-remitting MS (RRMS) patients. This study is designed to explore patient-reported experiences in real-life settings. METHODS Patients who were older than 18 years with a definite diagnosis of RRMS and no history of stem-cell transplantation were included. Outpatient clinic data files at the Neurology Department of Marmara University from June 2012 to June 2019 were examined retrospectively. RESULTS One hundred and ninety MS patients were enrolled. 118 FNG, 51 DMF, 44 TERI treatment cycles were recorded. Time sincedisease onset, time since diagnosis, and treatment duration were significantly longer for FNG (p = 0.012, p = 0.004, p < 0.001). 72.8% of all the treatment cycles were continued. There was no significant difference in treatment continuity between the 3 DMT groups. The most common reasons for treatment discontinuation in order of frequency were adverse events, the progression of the disease, and the persistence of relapses. No significant difference was found for treatment discontinuation reasons. 32% of the patients reported at least one AE. 28% FNG, 49 % DMF, and 27.3% TERI using patients reported AEs. AEs were much more frequently reported for DMF (p = 0.015). The most common adverse events for each DMT were alopecia (n = 6, 13.6%) for TERI, flushing for DMF (n = 20, 39.2%), and persistent lymphopenia for FNG (n = 9, 7.6%). No severe or life-threatening AE was reported for DMF, one patient experienced pancreatitis under TERI, and 11 (9.3%) patients using FNG had to stop treatment due to serious or life-threatening AEs including cardiac adverse events, opportunistic infections, and dysplasia. DISCUSSION Overall treatment discontinuation because of AEs is as low as 10.3% in this study. However, AEs are still the main reason for treatment drop-out.

Efficacy of Dimethyl Fumarate in Young Adults with Relapsing-Remitting Multiple Sclerosis: Analysis of the DEFINE, CONFIRM, and ENDORSE Studies. Neurol Ther 2023; 12:883-897. [PMID: 37061656 DOI: 10.1007/s40120-023-00475-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/07/2023] [Accepted: 03/27/2023] [Indexed: 04/17/2023] Open
Abstract
INTRODUCTION Dimethyl fumarate (DMF) showed favorable benefit-risk in patients with relapsing-remitting multiple sclerosis (MS) in phase 3 DEFINE and CONFIRM trials and in the ENDORSE extension study. Disease activity can differ in younger patients with MS compared with the overall population. METHODS Randomized patients received DMF 240 mg twice daily or placebo (PBO; years 0-2 DEFINE/CONFIRM), then DMF (years 3-10; continuous DMF/DMF or PBO/DMF; ENDORSE); maximum follow-up (combined studies) was 13 years. This integrated post hoc analysis evaluated safety and efficacy of DMF in a subgroup of young adults aged 18-29 years. RESULTS Of 1736 patients enrolled in ENDORSE, 125 were young adults, 86 treated continuously with DMF (DMF/DMF) and 39 received delayed DMF (PBO/DMF) in DEFINE/CONFIRM. Most (n = 116 [93%]) young adults completed DMF treatment in DEFINE/CONFIRM. Median (range) follow-up time in ENDORSE was 6.5 (2.0-10.0) years. Young adults entering ENDORSE who had been treated with DMF in DEFINE/CONFIRM had a model-based Annualized Relapse Rate (ARR; 95% CI) of 0.24 (0.16-0.35) vs. 0.56 (0.35-0.88) in PBO patients. ARR remained low in ENDORSE: 0.07 (0.01-0.47) at years 9-10 (DMF/DMF group). At year 10 of ENDORSE, EDSS scores were low in young adults: DMF/DMF, 1.9 (1.4); PBO/DMF, 2.4 (1.6). At ~ 7 years, the proportion of young adults with no confirmed disability progresion was 81% for DMF/DMF and 72% for PBO/DMF. Patient-reported outcomes (PROs) (SF-36 and EQ-5D) generally remained stable during ENDORSE. The most common adverse events (AEs) in young adults during ENDORSE were MS relapse (n = 53 [42%]). Most AEs were mild (n = 20 [23.3%], n = 7 [17.9%]) to moderate (n = 45 [52.3%], n = 23 [59.0%]) in the DMF/DMF and PBO/DMF groups, respectively. The most common serious AE (SAE) was MS relapse (n = 19 [15%]). CONCLUSION The data support a favorable benefit-risk profile of DMF in young adults, as evidenced by well-characterized safety, sustained efficacy, and stable PROs.

Dimethyl fumarate treatment of primary progressive multiple sclerosis: results of an open-label extension study. Mult Scler Relat Disord 2023; 70:104458. [PMID: 36586351 DOI: 10.1016/j.msard.2022.104458] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2022] [Revised: 12/02/2022] [Accepted: 12/07/2022] [Indexed: 12/13/2022]
Abstract
INTRODUCTION Dimethyl fumarate treatment is approved in Europe for patients with relapsing-remitting multiple sclerosis (MS) and in the US for relapsing forms of MS. We recently published the results of the first randomized placebo-controlled trial of 48 weeks of treatment with dimethyl fumarate or placebo in primary progressive MS (PPMS) (clinicaltrial.gov NCT02959658). The placebo-controlled phase of the trial did not meet its primary endpoint (reduction in cerebrospinal fluid concentrations of neurofilament light chain [NFL]). AIM To investigate the effects of dimethyl fumarate treatment in the open-label extension phase of the trial (week 48-96), where all patients were treated with DMF. METHODS Reported data are from screening, week 48, and week 96 visits. Patients were clinically evaluated with Expanded Disability Status Scale (EDSS), 9-Hole Peg Test (9HPT), Timed 25-Foot Walk (T25FW) test, Symbol Digit Modalities Test (SDMT), California Verbal Learning Test, and Brief Visuospatial Memory-Revised. Serum NFL concentrations were measured by single-molecule array analysis. MRI was performed on a 3 tesla MRI scanner and included: new/enlarging lesions, volume of lesions, cortical grey matter, putamen, thalamus, and normal-appearing white matter, and additional diffusion tensor imaging and magnetization transfer ratio measures. RESULTS Forty-two patients entered the open-label treatment phase, and 33 patients (61%) had complete data sets at week 96. The remaining 39% did not complete the trial and were not evaluated at week 96. We found no evidence of differences in clinical and MRI measures between patients initially treated with dimethyl fumarate and patients initially treated with placebo from baseline to week 48 and from week 48-96, where all patients were treated with dimethyl fumarate. Serum NFL concentrations remained stable in both groups over 96 weeks. Assessed with either EDSS, T25FW, or 9HPT at week 96, progression was observed for 14 patients (45%). Interestingly, another 15 patients (46%) had improvement in one or more of these domains. Applying a cut-off of 8 points, 2 (6%) patients worsened on SDMT, 25 (78%) did not change, and 5 (16%) improved. CONCLUSIONS Dimethyl fumarate treatment showed no effects on neither clinical nor MRI outcomes or changes in serum concentrations of NFL. An expected number of patients showed evidence of progression on standard clinical scales; however, this was matched by an equal number of patients improving. The reasons for the physical improvement in an unexpectedly high proportion of patients must be addressed in future studies.

Abstract
INTRODUCTION Alemtuzumab is a highly effective drug approved by the European Medicines Agency as a disease-modifying drug for the treatment of relapsing-remitting multiple sclerosis. OBJECTIVE A consensus document was drafted on the management of alemtuzumab in routine clinical practice in Spain. DEVELOPMENT A group of multiple sclerosis specialists reviewed articles addressing treatment with alemtuzumab in patients with multiple sclerosis and published before December 2017. The included studies assessed the drug's efficacy, effectiveness, and safety; screening for infections and vaccination; and administration and monitoring aspects. The initial proposed recommendations were developed by a coordinating group and based on the available evidence and their clinical experience. The consensus process was carried out in 2 stages, with the initial threshold percentage for group agreement established at 80%. The final document with all the recommendations agreed by the working group was submitted for external review and the comments received were considered by the coordinating group. CONCLUSION The present document is intended to be used as a tool for optimising the management of alemtuzumab in routine clinical practice.

Abstract
Background To compare the effectiveness of dimethyl fumarate (DMF) with subcutaneous interferon beta-1a (IFNβ-1a) in controlling disease activity in patients with relapsing–remitting Multiple Sclerosis (MS). Methods Clinical and imaging data from patients treated with either IFNβ-1a or DMF for at least one year were reviewed. The proportion of patients with at least one clinical relapse within 3–15 months after treatment onset, the proportion of patients with new T2 or gadolinium-enhancing lesions, and the proportion of subjects who achieved no evidence of disease activity (NEDA) status were assessed. Results Three hundred sixteen (98 on IFNβ-1a, 218 on DMF) subjects were included. Baseline demographics were comparable between groups except for age, disease duration, and the number of previous treatments being higher and relapse rate in the prior year being lower in the DMF-treated group. The proportion of patients having a clinical relapse (24.5% vs. 9.6%; OR = 3.04; P < 0.001) or a new MRI lesion (28.6% vs. 8.7%; OR = 4.19, P < 0.001) at 15 months were higher on IFNβ-1a. 79.9% of the patients achieved NEDA status at 15 months on DMF (vs. 51.1% for IFNβ-1a; OR = 0.26, P < 0.001). Further adjustment for demographics, disease characteristics, treatment and relapse history, and subgroup analyses confirmed these findings. Conclusion DMF was associated with less clinical and radiological disease activity compared to IFNβ-1a.

Abstract
Multiple sclerosis (MS) is a chronic disease affecting the brain and the spinal cord. It is a chronic inflammatory demyelinating disease of the central nervous system. It is the leading cause of non-traumatic disability in young adults. The clinical course of the disease is quite variable, ranging from stable chronic disease to rapidly evolving debilitating disease. The pathogenesis of MS is not fully understood. Still, there has been a rapid shift in understanding the immune pathology of MS away from pure T cell-mediated disease to B cells and microglia/astrocytes having a vital role in the pathogenesis of MS. This has helped in the emergence of new therapies for management. Effective treatment of MS requires a multidisciplinary approach to manage acute attacks, prevent relapses and disease progression and treat the disabling symptoms associated with the disease. In this review, we discuss the pathogenesis of MS, management of acute relapses, disease-modifying therapies in MS, new drugs and drugs currently in trial for MS and the symptomatic treatment of MS. All language search was conducted on Google Scholar, PubMed, MEDLINE, and Embase till February 2022. The following search strings and medical subheadings (MeSH) were used: "Multiple Sclerosis", "Pathogenesis of MS", and "Disease-modifying therapies in MS". We explored literature on the pathogenic mechanisms behind MS, management of acute relapses, disease-modifying therapies in MS and symptomatic management.

Abstract
Background: Dimethyl fumarate (DMF) is a drug currently in use in oral therapy for the treatment of relapsing-remitting multiple sclerosis (RRMS) due to its immunomodulatory and neuroprotective effects. The mechanisms by which DMF exerts its therapeutic effects in MS and in particular its influence on the oligodendrocytes (OLs) survival or differentiation have not yet been fully understood. Methods: Characterization of Oli neu cells was performed by immunocytochemistry and RT-PCR. The effect of DMF on cell proliferation and morphology was assessed by MTT assay, trypan blue staining, RT-PCR and Western blot analysis. The antioxidant and anti-inflammatory properties of DMF were analysed by ROS detection through DCFDA staining and lipid content analysis by Oil Red O staining and TLC. Results: DMF has been observed to induce a slowdown of cell proliferation, favoring the oligodendrocyte lineage cells (OLCs) differentiation. DMF has an antioxidant effect and is able to modify the lipid content even after the LPS-mediated inflammatory stimulus in Oli neu cells. Conclusions: The results obtained confirm that DMF has anti-inflammatory and antioxidant effects also on Oli neu cells. Interestingly, it appears to promote the OLCs differentiation towards mature and potentially myelinating cells.

Abstract
Over the recent years, the treatment of multiple sclerosis (MS) and neuromyelitis optica spectrum disorder (NMOSD) has evolved very rapidly and a large number of disease-modifying treatments (DMTs) are now available. However, most DMTs are associated with adverse events, the most frequent of which being infections. Consideration of all DMT-associated risks facilitates development of risk mitigation strategies. An international focused workshop with expert-led discussions was sponsored by the European Committee for Treatment and Research in Multiple Sclerosis (ECTRIMS) and was held in April 2021 to review our current knowledge about the risk of infections associated with the use of DMTs for people with MS and NMOSD and corresponding risk mitigation strategies. The workshop addressed DMT-associated infections in specific populations, such as children and pregnant women with MS, or people with MS who have other comorbidities or live in regions with an exceptionally high infection burden. Finally, we reviewed the topic of DMT-associated infectious risks in the context of the current SARS-CoV-2 pandemic. Herein, we summarize available evidence and identify gaps in knowledge which justify further research.

Lymphopenia during treatment with dimethyl fumarate in patients with multiple sclerosis: Prevalence, predicting factors and clinical outcomes. Mult Scler Relat Disord 2022; 57:103357. [PMID: 35158466 DOI: 10.1016/j.msard.2021.103357] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2021] [Revised: 10/06/2021] [Accepted: 10/28/2021] [Indexed: 01/01/2023]
Abstract
BACKGROUND Lymphopenia is a common side effect of treatment with dimethyl fumarate (DMF) in patients with multiple sclerosis (PwMS). Prevalence and predictive factors of this side effect are still uncertain, because literature has provided discrepant results and it is still a matter of debate if lymphopenia is associated with a better treatment outcome. METHODS We retrospectively recruited PwMS treated for at least one month with DMF and collected clinical, demographic data and absolute lymphocyte count (ALC) during follow-up. Lymphopenia was graded according to CTCAE. Patients according to the grade in lymphopenia (all grades) and severe lymphopenia (grade II-IV). To evaluate predictors of lymphopenia, we compared characteristics of patients with/without lymphopenia and patients with/without severe lymphopenia. A logistic binary regression was performed to elucidate any predictive factor of lymphopenia and severe lymphopenia. Area under the curve (AUC) was calculated to evaluate sensibility and specificity of predictors. We analyzed treatment outcome with NEDA-3 status at 1- and 2-years. RESULTS 98 of 105 patients treated with DMF were included. 46.9% developed lymphopenia, 27.6% severe lymphopenia. Lymphopenia was associated with basal ALC (p<0.001, AUC=0.786), treatment duration (p = 0.01, AUC=0.685),% of reduction at third month (p = 0.001, AUC=0.616) Severe lymphopenia was associated with basal ALC (p = 0.003, AUC=0.750).NEDA-3 status at 1-year (n = 66) and at 2-year (n = 44) did not differ in patients with/without lymphopenia (p = 0.059; p = 0.583) or with/without severe lymphopenia (p = 1.02; p = 0.169). CONCLUSION Lymphopenia is a common side effect of DMF and basal ALC predicts its development. Lymphopenia is not associated with the achievement of NEDA-3 status.

An Innovative Approach to Modelling the Optimal Treatment Sequence for Patients with Relapsing-Remitting Multiple Sclerosis: Implementation, Validation, and Impact of the Decision-Making Approach. Adv Ther 2022; 39:892-908. [PMID: 34796464 PMCID: PMC8866358 DOI: 10.1007/s12325-021-01975-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2021] [Accepted: 10/26/2021] [Indexed: 10/24/2022]
Abstract
INTRODUCTION An innovative computational model was developed to address challenges regarding the evaluation of treatment sequences in patients with relapsing-remitting multiple sclerosis (RRMS) through the concept of a 'virtual' physician who observes and assesses patients over time. We describe the implementation and validation of the model, then apply this framework as a case study to determine the impact of different decision-making approaches on the optimal sequence of disease-modifying therapies (DMTs) and associated outcomes. METHODS A patient-level discrete event simulation (DES) was used to model heterogeneity in disease trajectories and outcomes. The evaluation of DMT options was implemented through a Markov model representing the patient's disease; outcomes included lifetime costs and quality of life. The DES and Markov models underwent internal and external validation. Analyses of the optimal treatment sequence for each patient were based on several decision-making criteria. These treatment sequences were compared to current treatment guidelines. RESULTS Internal validation indicated that model outcomes for natural history were consistent with the input parameters used to inform the model. Costs and quality of life outcomes were successfully validated against published reference models. Whereas each decision-making criterion generated a different optimal treatment sequence, cladribine tablets were the only DMT common to all treatment sequences. By choosing treatments on the basis of minimising disease progression or number of relapses, it was possible to improve on current treatment guidelines; however, these treatment sequences were more costly. Maximising cost-effectiveness resulted in the lowest costs but was also associated with the worst outcomes. CONCLUSIONS The model was robust in generating outcomes consistent with published models and studies. It was also able to identify optimal treatment sequences based on different decision criteria. This innovative modelling framework has the potential to simulate individual patient trajectories in the current treatment landscape and may be useful for treatment switching and treatment positioning decisions in RRMS.

Abstract
BACKGROUND Dimethyl fumarate (DMF) demonstrated favorable benefit-risk in relapsing-remitting multiple sclerosis (RRMS) patients in phase-III DEFINE and CONFIRM trials, and ENDORSE extension. OBJECTIVE The main aim of this study is assessing DMF safety/efficacy up to 13 years in ENDORSE. METHODS Randomized patients received DMF 240 mg twice daily or placebo (PBO; Years 0-2), then DMF (Years 3-10; continuous DMF/DMF or PBO/DMF); maximum follow-up (combined studies), 13 years. RESULTS By January 2020, 1736 patients enrolled/dosed in ENDORSE (median follow-up 8.76 years (ENDORSE range: 0.04-10.98) in DEFINE/CONFIRM and ENDORSE); 52% treated in ENDORSE for ⩾6 years. Overall, 551 (32%) patients experienced serious adverse events (mostly multiple sclerosis (MS) relapse or fall; one progressive multifocal leukoencephalopathy); 243 (14%) discontinued treatment due to adverse events (4% gastrointestinal (GI) disorders). Rare opportunistic infections, malignancies, and serious herpes zoster occurred, irrespective of lymphocyte count. For DMF/DMF (n = 501), overall annualized relapse rate (ARR) remained low (0.143 (95% confidence interval (CI), 0.120-0.169)), while for PBO/DMF (n = 249), ARR decreased after initiating DMF and remained low throughout (ARR 0-2 years, 0.330 (95% CI, 0.266-0.408); overall ARR (ENDORSE, 0.151 (95% CI, 0.118-0.194)). Over 10 years, 72% DMF/DMF and 73% PBO/DMF had no 24-week confirmed disability worsening. CONCLUSION Sustained DMF safety/efficacy was observed in patients followed up to 13 years, supporting DMF's positive benefit/risk profile for long-term RRMS treatment.

Abstract
Background and Objective To study whether dimethyl fumarate is superior to placebo in decreasing CSF concentrations of neurofilament light chain (NFL) in patients with primary progressive MS (PPMS). Methods In the double-blind, placebo-controlled phase 2 study dimethyl FUMArate treatment in Progressive Multiple Sclerosis (FUMAPMS), patients with PPMS were randomly assigned to treatment with 240 mg dimethyl fumarate or placebo in a 1:1 ratio for 48 weeks. The primary endpoint was change in concentration of NFL in the CSF. Secondary endpoints included other CSF biomarkers and clinical and MRI measures. Efficacy was evaluated for the full data set by multiple imputations to account for missing data. Safety was assessed for the full data set. Results Fifty-four patients (mean age 54.9 years [SD 6.1], median Expanded Disability Status Scale 4.0 [nterquartile range 4.0–6.0], disease duration 14.1 [SD 9.4], and 21 [39%] female) were randomized to either placebo (n = 27) or dimethyl fumarate (n = 27) therapy. At screening CSF concentrations, adjusted for age and sex, of NFL, myelin basic protein (MBP), soluble CD27, chitinase 3-like 1, and B-cell maturation antigen were higher than in a group of symptomatic controls. Twenty-six patients (96%) in the dimethyl fumarate group and 24 patients (89%) in the placebo group completed the randomized phase. Mean change in CSF concentrations of NFL did not differ between groups (mean difference 99 ng/L; 95% CI −292 to 491 ng/L). MBP in CSF decreased in the treatment group (−182 ng/L, 95% CI −323 to −41 ng/L compared with placebo). The difference observed in the multiple imputation data set was not significant in a per protocol analysis. This was nominally significant in the multiple imputation data set but not in the per protocol analysis This was not found in the per protocol analysis Other secondary and tertiary outcomes were not affected. Various infections, lymphopenia, flushing, and gastrointestinal side effects were more frequent in the dimethyl fumarate group. Serious adverse events were similar between groups. Discussion Dimethyl fumarate treatment for 48 weeks had no effect on any of the investigated efficacy measures in patients with PPMS. We did not observe adverse events not anticipated for dimethyl fumarate treatment. Trial Registration Information Clinicaltrials.gov identifier NCT02959658. Classification of Evidence This study provides Class I evidence that for patients with PPMS, dimethyl fumarate treatment has no effect on CSF NFL levels compared with placebo treatment.

Abstract
In this narrative review, we analyze pre-registration and post-marketing data concerning hepatotoxicity of all disease-modifying therapies (DMTs) available for the treatment of relapsing-remitting multiple sclerosis, including beta interferon, glatiramer acetate, fingolimod, teriflunomide, dimethyl fumarate, cladribine, natalizumab, alemtuzumab, and ocrelizumab. We review the proposed causal mechanisms described in the literature and we also address issues like use of DMTs in patients with viral hepatitis or liver cirrhosis. Most data emerged in the post-marketing phase by reports to national pharmacovigilance agencies and published case reports or case series. Serious liver adverse events are rare, but exact incidence is largely unknown, as are predictive factors. Unfortunately, none of the DMTs currently available for the treatment of multiple sclerosis is free of potential hepatic toxic effects. Cases of acute liver failure have been reported for beta-interferon, fingolimod, natalizumab, alemtuzumab, and ocrelizumab by different mechanisms (idiosyncratic reaction, autoimmune hepatitis, or viral reactivation). Patients with multiple sclerosis should be informed about possible hepatic side effects of their treatment. Most cases of liver injury are idiosyncratic and unpredictable. The specific monitoring schedule for each DMT has been reviewed and the clinician should be ready to recognize clinical symptoms suggestive for liver injury. Not all DMTs are indicated in cirrhotic patients. For some DMTs, screening for hepatitis B virus and hepatitis C virus is required before starting treatment and a monitoring or antiviral prophylaxis schedule has been established. Beta interferon, glatiramer acetate, natalizumab, and alemtuzumab are relatively contraindicated in autoimmune hepatitis due to the risk of disease exacerbation.

Abstract
INTRODUCTION Viral, bacterial, or fungal infections are suspected of triggering multiple sclerosis (MS) and promoting relapses of the disease and are likely to be promoted by immune-active treatments. This raises questions about the infectious workup and preventive treatment of these infections prior to their initiation. OBJECTIVES To establish recommendations on infections and MS. Provide information to patients and healthcare professionals on the minimal infectious workup to be performed in an MS patient at diagnosis and prior to initiation of immuno-active therapy in MS. METHODS The recommendation attempts to answer four main questions about infections and MS. The French Group for Recommendations in Multiple Sclerosis (France4MS) did a systematic review of articles from PubMed and universities databases (from January 1975 to June 2020), using the RAND/UCLA formalized consensus method. The RAND/UCLA method has been developed to synthesize the scientific literature and expert opinions on health care topics and was used for reaching a formal agreement. Twenty-three experts contributed to the detailed review and a group of 63 multidisciplinary health professionals validated the final version of 36 recommendations. RESULTS It is recommended that MS patients undergo a minimal infectious workup, check their vaccination status at diagnosis, and repeat it during follow-up and before starting immunotherapy. Screening and preventive treatment of viral (group Herpes virus, HPV, JCV, HCV, HBV), bacterial (mycobacteria) and fungal (Cryptococcus) infections is recommended prior to the initiation of certain immuno-active MS therapies. DISCUSSION AND CONCLUSIONS At diagnosis of MS and prior to the choice of therapeutic strategy, it is recommended to update the vaccination schedule of MS patients in reference to the HCSP vaccination schedule and the SFSEP recommendations. Before starting immunosuppressive treatment, it is recommended to inform patients of the risks of infections and to look for a constitutive or acquired immune deficiency. Health professionals and patients should be informed of the updated recommendations on infections and MS.

Abstract
Background The aim of this observational study is to investigate the efficacy and safety of two approved oral disease-modifying therapies (DMTs) in patients with remitting-relapsing multiple sclerosis (RRMS): dimethyl fumarate (DMF) vs. teriflunomide (TRF). Methods A total of 159 RRMS patients (82 on TRF and 77 on DMF) were included. The expanded disability status scale (EDSS), confirmed disability improvement (CDI), confirmed disability progression (CDP), and annualized relapse rate (ARR) were evaluated for the two-year period prior to enrollment in our study. The drug-associated adverse effects (AEs) were recorded. We conducted propensity matching score to compare the efficacy between TRF and DMF. Results After matching for the confounders, TRF- and DMF-treated groups were not different in terms of EDSS (P value = 0.54), CDI (P value = 0.80), CDP (P value = 0.39), and ARR (P value >0.05). TRF discontinuation occurred in 2 patients (2.43%) due to mediastinitis and liver dysfunction, while a patient (1.29%) discontinued DMF due to depression. Incidence rate of AEs in the TRF-treated group was 81.4%: hair thinning (hair loss) (62.9%), nail loss (20.9%), and elevated aminotransferase (14.8%) were the most common AEs; in DMF-treated patients, AEs were 88.2% with predominance of flushing (73.2%), pruritus (16.9%), and abdominal pain (16.9%). Conclusion Based on our findings, DMF is as efficacious and safe as TRF for the treatment of RRMS in our Iranian study population. Multicentric studies need to corroborate these findings in other populations.

Abstract
Background There are currently no best practice recommendations for lymphocyte subset monitoring for patients with multiple sclerosis (pwMS) on disease-modifying therapies including Tecfidera® (dimethyl fumarate, DMF). However, there have been several cases of pwMS on DMF without severe lymphopenia who had high CD4:CD8 T cell ratios and went on to develop progressive multifocal leukoencephalopathy. Objective Our objective was to characterize the changes in immune profile during and after DMF treatment in pwMS. Methods A retrospective analysis of longitudinal data from 299 pwMS who have been treated with DMF at the Fraser Health Multiple Sclerosis Clinic in British Columbia, Canada. The blood test results were taken from January 1, 2013 to April 1, 2020. Results Our results suggest that CD8+ T cells had the highest proportional decrease compared to other lymphocyte subset populations and overall lymphocyte count in response to DMF treatment. CD56+ Natural Killer cells were similarly decreased in response to DMF treatment. CD4:CD8 T cell ratio was the measurement that had the highest rate of change in response to DMF initiation and discontinuation. Conclusion CD8+ T cell count and CD4:CD8 T cell ratio may be a more sensitive measurement of the immune landscape of patients with MS on DMF.

Abstract
INTRODUCTION Alzheimer's disease (AD) is the leading cause of dementia and a major global health issue. Currently, only limited treatment options are available to patients. One possibility to expand the treatment repertoire is repurposing of existing drugs such as dimethyl fumarate (DMF). DMF is approved for treatment of multiple sclerosis and previous animal studies have suggested that DMF may also have a beneficial effect for the treatment of AD. METHODS We used an APPPS1 transgenic model of senile β-amyloidosis and treated female mice orally with DMF in two treatment paradigms (pre and post onset). We quantified learning and memory parameters, β-amyloidosis, and neuroinflammation to determine the potential of DMF as AD therapeutics. RESULTS Treatment with DMF had no influence on water maze performance, β-amyloid accumulation, plaque formation, microglia activation, and recruitment of immune cells to the brain. Compared to vehicle-treated animals, oral DMF treatment could not halt or retard disease progression in the mice. DISCUSSION Our results do not favour the use of DMF as treatment for AD. While our results stand in contrast to previous findings in other models, they emphasize the importance of animal model selection and suggest further studies to elucidate the mechanisms leading to conflicting results.

Abstract
Diroximel fumarate (Vumerity®), an orally administered disease-modifying drug (DMD), expands the available treatment options for adults with relapsing forms of multiple sclerosis (MS), including clinically isolated syndrome, relapsing-remitting MS (RRMS), and active secondary progressive MS. It demonstrates bioequivalence to dimethyl fumarate and was developed to provide similar clinical benefits, but with an improved gastrointestinal (GI) tolerability profile. In RRMS patients who are treatment-naïve or were previously treated with interferon-β or glatiramer acetate, diroximel fumarate reduces annualized relapse rates, with most patients experiencing no relapses during treatment, and reduces the formation of new MS-associated brain lesions. Diroximel fumarate has an acceptable tolerability profile that is consistent with that of dimethyl fumarate, albeit with a significantly lower rate of GI adverse events.

Abstract
Multiple sclerosis (MS) is a chronic inflammatory disease of the central nervous system. In recent years, many disease-modifying therapies (DMT) have been approved for MS treatment. For this reason, a profound knowledge of the characteristics and indications of the available compounds is required to tailor the therapeutic strategy to the individual patient characteristics. This should include the mechanism of action and pharmacokinetic of the drug, the safety and efficacy profile provided by clinical trials, as well as the understanding of possible side effects. Moreover, the evolving knowledge of the disease is paving the way to new and innovative therapeutic approaches, as well as the development of new biomarkers to monitor the therapeutic response and to guide the clinician's therapeutic choices. In this review we provide a comprehensive overview on currently approved therapies in MS and the emerging evidence-based strategies to adopt for initiating, monitoring, and eventually adapting a therapeutic regimen with DMT.

Abstract
Multiple sclerosis (MS) is a prevalent neurologic autoimmune disorder affecting two million people worldwide. Symptoms include gait abnormalities, perception and sensory losses, cranial nerve pathologies, pain, cognitive dysfunction, and emotional aberrancies. Traditional therapy includes corticosteroids for the suppression of relapses and injectable interferons. Recently, several modern therapies-including antibody therapy and oral agents-were approved as disease-modifying agents. Monomethyl fumarate (MMF, Bafiertam) is a recent addition to the arsenal available in the fight against MS and appears to be well-tolerated, safe, and effective. In this paper, we review the evidence available regarding the use of monomethyl fumarate (Bafiertam) in the treatment of relapsing-remitting MS.

Abstract
Human CD4+CD25hiFOXP3+ regulatory T (Treg) cells are key players in the control of immunological self-tolerance and homeostasis. Here, we report that signals of pseudo-starvation reversed human Treg cell in vitro anergy through an integrated transcriptional response, pertaining to proliferation, metabolism, and transmembrane solute carrier transport. At the molecular level, the Treg cell proliferative response was dependent on the induction of the cystine/glutamate antiporter solute carrier (SLC)7A11, whose expression was controlled by the nuclear factor erythroid 2-related factor 2 (NRF2). SLC7A11 induction in Treg cells was impaired in subjects with relapsing-remitting multiple sclerosis (RRMS), an autoimmune disorder associated with reduced Treg cell proliferative capacity. Treatment of RRMS subjects with dimethyl fumarate (DMF) rescued SLC7A11 induction and fully recovered Treg cell expansion. These results suggest a previously unrecognized mechanism that may account for the progressive loss of Treg cells in autoimmunity and unveil SLC7A11 as major target for the rescue of Treg cell proliferation.

Abstract
Background There is limited data analyzing the safety and effectiveness of dimethyl fumarate (DMF) in the progressive multiple sclerosis (PMS) population. Objective To analyze the safety and effectiveness of DMF in patients with PMS. Methods We used Cox proportional hazards models to compare the time to confirmed worsening and improvement on the Expanded Disability Status Scale (EDSS) and timed 25-foot walk (T25FW) between patients treated with DMF and glatiramer acetate (GA) for at least one year. Results We included 46 patients treated with DMF and 42 patients treated with GA. The safety and tolerability of GA and DMF were consistent with established profiles. There was no difference in confirmed EDSS progression. A trend towards reduced T25FW was seen in the DMF compared to GA after adjustment (HR = 0.86; 95% CI:0.37, 1.98; p = 0.72 and HR = 0.60; 95% CI:0.27, 1.34; p = 0.21, respectively). Conclusion Dimethyl fumarate showed a trend towards reduction in T25FW but no evidence of clinically significant impact on EDSS. The small sample precluded definitive determination.

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.

Abstract
OBJECTIVE Macrophage activation syndrome (MAS) is characterized by increased serum levels of ferritin and heme oxygenase 1 (HO-1), and yet no known function is ascribed to these molecules in MAS. Because HO-1 is antiinflammatory, we hypothesized that pharmacologic activation of HO-1 could ameliorate MAS disease activity. Dimethyl fumarate (DMF), a treatment approved by the US Food and Drug Administration for multiple sclerosis, activates HO-1. Monomethyl fumarate (MMF) is the active metabolite of DMF. We therefore evaluated whether MMF could elicit HO-1-dependent therapeutic improvements in a murine model of MAS. METHODS We induced MAS by repeated activation of Toll-like receptor 9 (TLR-9) in wild-type and myeloid-specific HO-1-deficient mice. MMF was administered twice daily to test its efficacy. We assessed organ weights, serum cytokine levels, histologic features of the spleen and liver tissue, and complete blood cell counts to evaluate disease activity. Statistical testing was performed using Student's t-test or by 2-way analysis of variance as appropriate. RESULTS The presence of HO-1 was required for the majority of TLR-9-induced interleukin-10 (IL-10). IL-10 production in TLR-9-induced MAS was found to correlate with the myeloid-HO-1 gene dose in myeloid cells (P < 0.001). MMF treatment increased the levels of HO-1 in splenic macrophages by ~2-fold (P < 0.01), increased serum levels of IL-10 in an HO-1-dependent manner in mice with TLR-9-induced MAS (P < 0.005), and improved multiple disease parameters in both an HO-1-dependent and HO-1-independent manner. CONCLUSION TLR-9-induced production of IL-10 is regulated by HO-1 activity both in vitro and in vivo. Therapeutic enhancement of the HO-1/IL-10 axis in a murine model was able to significantly ameliorate MAS disease activity. These results suggest that HO-1 may be viable as a MAS therapeutic target, and treatment with DMF and MMF should be considered in future investigations of MAS therapy.

Abstract
PURPOSE OF REVIEW To summarize the currently known side effects of the approved therapies of multiple sclerosis and to suggest monitoring procedures. RECENT FINDINGS The progress in the treatment of multiple sclerosis with new very effective therapies is accompanied by a number of side effects. Some of these have already been described in the approval studies, but some only after approval in a real world situation. The reason for this is the short duration of the clinical studies, the very heterogeneous patient profile in the real world setting with a number of comorbidities, pretherapies, and wider age range. The side effects may occur during application of therapies or afterwards during the course of the treatment. The side effects may range from mild infections, mild laboratory abnormalities, secondary autoimmune diseases to life-threatening side effects such as progressive multifocal leukoencephalopathy. SUMMARY It has to be pointed out that these side effects are not to be considered as final and neurologists should be vigilant against new unknown side effects. The doctor should be aware of these undesirable effects, should weigh the benefits of the therapies against the risks, but at the same time she/he should keep in mind that multiple sclerosis can be a very disabling disease if not treated properly.

Abstract
BACKGROUND Potential increase of cancer incidence is one of the main safety concerns of the disease-modifying therapies employed in Multiple Sclerosis (MS). OBJECTIVE Detailed description of patients who developed cancer among a prospective cohort of Spanish MS patients on dimethyl fumarate (DMF) treatment. METHODS We describe patients who developed cancer among a cohort of 886 MS patients on DMF treatment (2681 patient-years), with a median time of exposure of 39.5 months (IQR 23-51.5), who participated in a multicentre and prospective real-world study conducted in 16 Spanish National Health System hospitals from February 2014 to May 2019. Local researchers were periodically contacted by the investigation team to monitor safety issues. Cancer histories were collected from the medical records and the information was updated at July 30th 2020. RESULTS Eight Caucasian women developed cancer, which accounts for 0.9% and an accumulated malignancy rate of 298.39 cases per 100,000 patient-years of DMF exposure. At the time of cancer diagnosis, age was between 33 to 67 years and median time on DMF treatment 16.5 months (range 1-53). Two patients had familiar history of cancer. No specific cancer lines were found (breast cancer in 2 cases, thyroid in 3, urothelial carcinoma, cervix and a progression to leiomyosarcoma from a mitotically active leiomyoma). DMF was withdrawn during cancer treatment in 6 patients and reintroduced later. All cancers except one are in complete remission. The patient with leiomyosarcoma died by cancer progression. CONCLUSION A relationship between cancers and DMF is unlikely because the malignancy rate was similar to that of the age-and sex-matched general population, and because of the absence of specific tumour cell lines. Nevertheless, as with other immunosuppressive DMTs, clinicians treating MS should be aware of any potential cancer symptom and demand proper testing.

Abstract
BACKGROUND Real-world safety data for the oral multiple sclerosis (MS) disease-modifying therapies (DMTs), dimethyl fumarate (DMF), fingolimod, and teriflunomide are important. We examined laboratory test abnormalities and adverse health conditions in new users. METHODS Linked laboratory and administrative health data were accessed for all persons with MS (PwMS) filling their first oral DMT prescription in two Canadian provinces. PwMS were followed from first prescription fill until discontinuation, death, emigration or study end. Proportions of PwMS, and incidence rates (IR)/100 person-years, were calculated for ≥1 event of elevated alanine aminotransferase (ALT) (>the upper limit of normal [ULN]; all DMTs), liver toxicity (ALT>3xULN; fingolimod); lymphopenia and proteinuria (DMF), and cardiac arrhythmia, hypertension and pneumonia (all DMTs). RESULTS Overall, 1,140 PwMS were followed for up to 2 years. De novo elevated alanine aminotransferase affected 13.2% (DMF), 12.4% (teriflunomide), and 30.0% (fingolimod) of users. Liver toxicity affected 2.8% of fingolimod, lymphopenia 3.1% of DMF, and proteinuria 2.9% of DMF users. The incidences of cardiac arrhythmia, pneumonia and hypertension ranged from <1 to 1.86/100 person-years depending on the DMT. CONCLUSIONS The short-term, real-world incidences of abnormal laboratory results or adverse events were consistent with the pivotal clinical trial findings. Longer-term safety data are still needed.

Abstract
Background: Pediatric multiple sclerosis (MS) is rare: only 1.5-5% of MS cases are diagnosed before 18 years of age, and data on disease-modifying therapies (DMTs) for pediatric MS are limited. The CONNECTED study assessed the long-term safety and efficacy of treatment with delayed-release dimethyl fumarate (DMF), an oral MS DMT, in pediatric patients with MS. Methods: CONNECTED is the 96-week extension to FOCUS, a 24-week phase 2 study of patients aged 13-17 years; participants received DMF 240 mg twice daily. Endpoints included (primary) incidence of adverse events (AEs), serious AEs, and DMF discontinuations due to an AE, and (secondary) T2 hyperintense lesion incidence by magnetic resonance imaging and annualized relapse rate (ARR). Results: Twenty participants [median (range) age, 17 (14-18) years; 65% female] who completed FOCUS enrolled into CONNECTED; 17 (85%) completed CONNECTED. Eighteen participants (90%) experienced AEs: the most frequent was flushing (25%). None experienced infections or fever related to low lymphocyte counts. Three participants experienced four serious AEs; none led to DMF discontinuation. Twelve of 17 participants (71%) had no new/newly enlarged T2 lesions from weeks 16-24, two (12%) had one, and one each (6%) had two, three, or five or more lesions [median (range), 0 (0-6)]. Over the full 120-week treatment period, ARR was 0.2, an 84.5% relative reduction (n = 20; 95% confidence interval: 66.8-92.8; p < 0.0001) vs. the year before DMF initiation. Conclusions: The long-term safety and efficacy observed in CONNECTED was consistent with adults, suggesting pediatric and adolescent patients with MS might benefit from DMF treatment.

Abstract
BACKGROUND Dimethyl fumarate (DMF) has shown efficacy in reducing relapse rates in patients with multiple sclerosis (MS). However, associated adverse effects (AE) such as gastrointestinal (GI) AE, flushing and lymphopenia are the main cause of treatment discontinuation. The aim of this study was to evaluate the effectiveness of DMF, and to assess strategies to reduce treatment discontinuation rates in routine clinical practice. PATIENTS AND METHODS Ninety patients started DMF treatment between August 2015 and February 2020. Prior to DMF therapy, patients received written information regarding treatment and the management of AE, along with medical prescriptions. Clinical and analytical data were collected at clinical visits performed at least 6-monthly, and disease progression was evaluated by brain magnetic resonance imaging (MRI). RESULTS Prior to DMF, 78.7% of patients had an annualized relapse rate (ARR) of 1.07 (range: 1-3) and median Expanded Disability Status Scale (EDSS) score of 1.0 (range: 0-2). At final follow-up, ARR and median EDSS scores were significantly reduced to 0.09 (range: 0-2; p< 0.001) and 0 (range: 0-1.625; p< 0.001), respectively. Just over one quarter of patients with brain MRI (26.8% of 71 patients) showed improvement in disease activity based on MRI evaluation. Lymphopenia was associated with previous treatment lines (p=0.042) and longer disease duration (p=0.032). A total of twelve patients abandoned DMF treatment, mainly due to lymphopenia (7.9%), but none did it because of GI AE or flushing. CONCLUSION In our series, DMF showed high clinical and radiological efficacy. Providing patients with complete information prior to treatment on the management of associated AE helps them to better understand what to expect, improves tolerance and reduces clinical and telephone consultations, which may help to reduce the use and cost of healthcare resources.

Abstract
BACKGROUND Tecfidera® (dimethyl fumarate [DMF]) is an approved product for the treatment of relapsing forms of multiple sclerosis. Monomethyl fumarate (MMF) is the only active metabolite of DMF and is responsible for its therapeutic efficacy. OBJECTIVE The objective of this study was to determine whether two Bafiertam™ capsules each containing 95 mg of MMF is bioequivalent to one Tecfidera® capsule containing 240 mg of DMF, a prodrug of MMF. METHODS This was a single-dose, open-label, randomized, two-way crossover study evaluating two treatments over two periods with a washout interval between treatments. Fifty healthy subjects were randomized to receive a single dose of the test drug MMF 190 mg as 2 × 95 mg delayed-release capsules or the reference drug DMF 240 mg as a 1 × 240-mg delayed-release capsule. Blood samples were obtained prior to dosing and at prespecified time points through 24 h post-dose to determine plasma concentrations of MMF. The pharmacokinetic parameters of MMF were calculated including maximum observed concentration, time to reach maximum observed concentration, apparent half-life of the drug in plasma, AUC0-t which is the area under the plasma concentration-time curve (AUC) from time zero (dosing time) to the last time point, t, with measurable analyte concentration, and AUC0-inf, which is AUC0-t plus the extrapolated AUC from time t to infinity. RESULTS The geometric least-squares mean ratios (90% confidence interval) of the test drug MMF vs the reference drug DMF were 96.80% (92.18-101.64), 96.35% (91.81-101.12), and 104.84% (95.54-115.05) for AUC0-t, AUC0-inf, and maximum observed concentration, respectively. Two capsules of Bafiertam™ was safe and generally well tolerated. The most common adverse event for both products was flushing, 60% and 51%, for Bafiertam™ and Tecfidera®, respectively. CONCLUSIONS Based on the statistical analysis results of the pharmacokinetic parameters of MMF, a single oral dose of two Bafiertam™ DR 95 mg capsules is bioequivalent to a single oral dose of one Tecfidera® DR 240 mg capsule. CLINICAL TRIAL REGISTRATION This study was retrospectively registered with ClinicalTrials.gov (NCT04570670) on 30 September, 2020.

Abstract
BACKGROUND Dimethyl fumarate (DMF) has demonstrated efficacy in phase III studies. However, real-world data are still limited. OBJECTIVE The objective of this study was to describe the profile of patients who receive DMF and to assess the effectiveness of DMF regarding relapses, disability progression, magnetic resonance imaging activity, and NEDA (No Evidence Disease Activity)-3 status in a Spanish population in a real-world setting. METHODS We conducted a multicenter prospective study of patients who started DMF between 2014 and 2019 in Spain. Three subgroups were considered: naïve, switch to DMF because of inefficacy, and switch to DMF because of adverse effects. The effects of DMF on clinical and radiological measures were evaluated. RESULTS Among 886 patients, 25.3% were naïve, 28.8% switched because of adverse effects, and 45.9% because of inefficacy. Median follow-up was 38.9 (interquartile range 22.6-41.8) months. Annualized relapse rates were 0.15, 0.10, and 0.10 at 12, 24, and 36 months respectively, and 77.7% of patients were relapse free at month 42. At 12, 24, and 42 months, 96.1%, 87.4%, and 79.7% of patients were progression free, respectively. The number of T1 gadolinium-enhancement (T1Gd+) lesions was 0.19, 0.14, and 0.18 at 12, 24, and 36 months. NEDA-3 status at month 42 was maintained by 49.8% of patients. Relapsing was associated with higher annualized relapse rates the year before (hazard ratio 1.34, p < 0.001) and to the inefficacy switch vs naïve group (hazard ratio 1.76, p = 0.003). A higher baseline Expanded Disability Status Scale score was associated with disability progression (hazard ratio 1.15, p = 0.003) and more T1Gd+ lesions (hazard ratio 1.07, p < 0.001) with radiological progression. A higher baseline Expanded Disability Status Scale score, a larger number of T1Gd+ lesions, and a switch because of inefficacy (vs adverse events) were all risk factors for losing NEDA-3 status. DMF was discontinued in 29.9% of patients, in 13.5% because of inefficacy. CONCLUSIONS Our findings confirm the sustained effectiveness of DMF on the clinical and radiological activity of multiple sclerosis in a real-world setting, both in naïve patients and in those switching from other multiple sclerosis therapies.

Abstract
INTRODUCTION Compared with the non-Hispanic/non-Latino population, Hispanic/Latino patients with multiple sclerosis (MS) are reported to exhibit greater disease severity. Geographical location and genetics play a role in differences observed across Hispanic/Latino subpopulations. We evaluated real-world safety and effectiveness of dimethyl fumarate (DMF) on MS disease activity in Hispanic/Latino patients. METHODS ESTEEM is an ongoing, 5-year, multinational, prospective study evaluating long-term safety and effectiveness of DMF in patients with MS. This interim analysis included patients newly prescribed DMF in routine practice at 394 sites globally. RESULTS Overall, 4986 non-Hispanic/non-Latino and 98 Hispanic/Latino patients were analyzed; median (range) follow-up was 18 (2-37) months. Unadjusted annualized relapse rates (ARRs) for 12 months before DMF initiation versus 36 months post DMF initiation, respectively, were: non-Hispanic/non-Latino patients, 0.82 (95% CI 0.80-0.84) versus 0.10 (95% CI 0.09-0.10), 88% lower ARR (P < 0.0001); Hispanic/Latino patients, 0.80 (95% CI 0.65-1.00) versus 0.09 (95% CI 0.06-0.14), 89% lower ARR (P < 0.0001). In total, 28 (29%) Hispanic/Latino patients reported adverse events leading to treatment discontinuation; gastrointestinal (GI) disorders (n = 10, 10%) were the most common, consistent with the non-Hispanic/non-Latino population (8%). Median lymphocyte counts decreased by approximately 24% in the first year (vs 36% decrease in non-Hispanic/non-Latino patients) then remained stable and above the lower limit of normal in most patients. CONCLUSIONS Relapse rates remained low in Hispanic/Latino patients, consistent with non-Hispanic/non-Latino patients. The safety profile of DMF in Hispanic/Latino patients was consistent with safety findings from the non-Hispanic/non-Latino ESTEEM population, demonstrating the real-world treatment benefit of DMF in the Hispanic/Latino patient cohort.

Abstract
OBJECTIVES Establish recommendations for the management of UTIs in MS patients. BACKGROUND Urinary tract infections (UTIs) are common during multiple sclerosis (MS) and are one of the most common comorbidities potentially responsible for deaths from urinary sepsis. METHODS The recommendations attempt to answer three main questions about UTIs and MS. The French Group for Recommendations in MS (France4MS) did a systematic review of articles from PubMed and universities databases (01/1980-12/2019). The RAND/UCLA appropriateness method, which has been developed to synthesize the scientific literature and expert opinions on health care topics, was used for reaching a formal agreement. 26 MS experts worked on the full-text review and a group of 70 multidisciplinary health care specialists validated the final evaluation of summarized evidences. RESULTS UTIs are not associated with an increased risk of relapse and permanent worsening of disability. Only febrile UTIs worsen transient disability through the Uhthoff phenomenon. Some immunosuppressive treatments increase the risk of UTIs in MS patients and require special attention especially in case of hypogammaglobulinemia. Experts recommend to treat UTIs in patients with MS, according to recommendations of the general population. Prevention of recurrent UTIs requires stabilization of the neurogenic bladder. In some cases, weekly oral cycling antibiotics can be proposed after specialist advice. Asymptomatic bacteriuria should not be screened for or treated systematically except in special cases (pregnancy and invasive urological procedures). CONCLUSION Physicians and patients should be aware of the updated recommendations for UTis and MS.

Abstract
INTRODUCTION Black or African American (black/AA) patients with multiple sclerosis (MS) are reported to exhibit greater disease severity compared with non-black or non-AA patients. Whether differences exist in response to MS disease-modifying therapies remains uncertain, as MS clinical trials have included low numbers of non-white patients. We evaluated real-world safety and effectiveness of dimethyl fumarate (DMF) on MS disease activity in black/AA patients. METHODS ESTEEM is an ongoing, 5-year, multinational, prospective study evaluating long-term safety and effectiveness of DMF in patients with MS. This interim analysis included patients newly prescribed DMF in routine practice at 394 sites globally. RESULTS Overall, 4897 non-black/non-AA and 187 black/AA patients were analyzed; median (range) follow-up 18 (2-37) months. Unadjusted annualized relapse rates (ARRs) for 12 months before DMF initiation versus 36 months post DMF initiation, respectively, were: non-black/non-AA patients, 0.83 (95% CI 0.80-0.85) versus 0.10 (95% CI 0.09-0.10), 88% lower ARR (P < 0.0001); black/AA patients, 0.68 (95% CI 0.58-0.80) versus 0.07 (95% CI 0.05-0.10), 90% lower ARR (P < 0.0001). In total, 35 (19%) black/AA patients reported adverse events leading to treatment discontinuation; gastrointestinal disorders were most common (7%), consistent with non-black/non-AA patients (8%). Median lymphocyte counts decreased by 22% in the first year (vs 36% in non-black/non-AA patients), then remained stable and above lower limit of normal in most patients. CONCLUSIONS Relapse rates remained low in black/AA patients, consistent with non-black/non-AA patients. The safety profile of DMF in black/AA patients was consistent with that in the non-black/non-AA ESTEEM population, although lymphocyte decrease was less pronounced in black/AA patients.

Effectiveness of Dimethyl Fumarate in Patients With Relapsing Multiple Sclerosis Switching After Suboptimal Response to Glatiramer Acetate, Including Patients With Early Multiple Sclerosis: Subgroup Analysis of RESPOND. Neurol Ther 2020; 10:169-182. [PMID: 33225410 PMCID: PMC8140000 DOI: 10.1007/s40120-020-00223-2] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/07/2020] [Accepted: 10/30/2020] [Indexed: 01/22/2023] Open
Abstract
Introduction This post hoc subset analysis of RESPOND evaluated the effectiveness of dimethyl fumarate (DMF) 240 mg twice daily in patients with relapsing multiple sclerosis (RMS) after suboptimal response to glatiramer acetate (GA; “first switch” patients), including patients with early MS (“early MS switch” patients). Methods Patients had discontinued GA due to suboptimal response and initiated DMF treatment within 60 days after enrollment. Relapse data were collected from medical records. First switch patients had had one prior approved MS therapy (GA) before initiating DMF treatment. Early MS switch patients were first switch patients with baseline Patient-Reported Expanded Disability Status Scale (PR-EDSS) score ≤ 3.5, ≤ 1 relapses in the past 1 year, or both. Results Among first switch patients (n = 231), the annualized relapse rate (ARR) was 0.48 (95% confidence interval [CI] 0.40–0.58) for 12 months before DMF initiation and 0.11 (95% CI 0.06–0.18) for 12 months after DMF initiation, a 78% decrease in ARR. Among early MS switch patients with baseline PR-EDSS score ≤ 3.5 (n = 120), ≤ 1 relapses in the prior year (n = 219), or both (n = 114), the ARRs (95% CIs) for 12 months before DMF initiation were 0.47 (0.37–0.59), 0.37 (0.32–0.44), and 0.39 (0.31–0.49), respectively; values for 12 months after DMF initiation were 0.06 (0.02–0.19), 0.09 (0.05–0.17), and 0.06 (0.02–0.20), respectively, an 87, 75, and 83% decrease in ARR. The proportion of patients relapse-free 12 months after DMF initiation versus 12 months before were 94 versus 59% in first switch patients, and 97 versus 58%, 94 versus 63%, and 97 versus 61% in early MS switch patients in the PR-EDSS score ≤ 3.5, ≤ 1 relapses in the prior year, or PR-EDSS score ≤ 3.5 and ≤ 1 relapses subgroups, respectively. After 12 months of DMF treatment, most patient-reported outcomes scores showed significant improvement. Conclusions DMF may be an effective treatment option in first switch and early MS switch patients with RMS who experience a suboptimal response to GA.

Abstract
Supplemental digital content is available in the text. BACKGROUND: Gastrointestinal (GI) adverse events (AEs) are commonly encountered with delayed-release dimethyl fumarate (DMF), an approved treatment for relapsing multiple sclerosis (MS). METHODS: Two hundred thirty-nine MS nurses from 7 countries were asked to complete a 2-round Delphi survey developed by a 7-member steering committee. Questions pertained to approaches for mitigating DMF-associated GI AEs. RESULTS: Ninety-six percent of nurses followed the label recommendation for DMF dose titration in round 1, but 77% titrated the DMF dose more slowly than recommended in round 2. Although 86% of nurses advised persons with relapsing forms of MS (PWMS) to take DMF with food, patients were not routinely informed of appropriate types of food to take with DMF. Most nurses recommended both pharmacologic and nonpharmacologic symptomatic therapies for PWMS who experienced GI AEs on DMF. Pharmacologic and nonpharmacologic symptomatic therapies were regarded as equally effective at keeping PWMS on DMF. In round 2, 58% of nurses stated that less than 10% of PWMS who temporarily discontinued DMF went on to permanently discontinue treatment. Sixty-six percent of nurses stated that less than 10% of PWMS permanently discontinued DMF because of GI AEs in the first 6 months of treatment in round 1. Most nurses agreed that patient education on potential DMF-associated GI AEs contributes to adherence. CONCLUSION: This first real-world nurse-focused assessment of approaches to caring for PWMS with DMF-associated GI AEs suggests that, with implementation of slow dose titration, symptomatic therapies, and educational consultations, most PWMS can remain on DMF and, when necessary after temporary discontinuation, successfully restart DMF.

Abstract
Dimethyl fumarate (DMF) is a first line medication for multiple sclerosis. It has a favourable safety profile, however, there is concern regarding the occurrence of moderate-severe and sustained lymphopenia and the associated risk of progressive multifocal leukoencephalopathy. We carried out an extensive literature review to understand the molecular mechanisms underlying this adverse reaction. Dynamic changes in certain components of the immune system are likely to be important for the therapeutic effects of DMF, including depletion of memory T cells and decrease in activated T cells together with expansion of naïve T cells. Similar modifications were reported for the B cell components. CD8+ T cells are particularly susceptible to DMF-induced cell death, with marked reductions observed in lymphopenic subjects. The reasons underlying such increased sensitivity are not known, nor it is known how expansion of other lymphocyte subsets occurs. Understanding the molecular mechanisms underlying DMF action is challenging: in vivo DMF is rapidly metabolized to monomethyl fumarate (MMF), a less potent immunomodulator in vitro. Pharmacokinetics indicate that MMF is the main active species in vivo. However, the relative importance of DMF and MMF in toxicity remains unclear, with evidence presented in favour of either of the compounds as toxic species. Pharmacogenetic studies to identify genetic predictors of DMF-induced lymphopenia are limited, with inconclusive results. A role of the gut microbiome in the pharmacological effects of DMF is emerging. It is clear that further investigations are necessary to understand the mechanisms of DMF-induced lymphopenia and devise preventive strategies. Periodic monitoring of absolute lymphocyte counts, currently performed in clinical practise, allows for the early detection of lymphopenia as a risk-minimization strategy.

Abstract
BACKGROUND AND PURPOSE Dimethyl fumarate (DMF) causes a mean lymphocyte count drop of approximately 30% in relapsing-remitting multiple sclerosis (RRMS) patients. The relationship between this reduction and DMF effectiveness is controversial. The objective was to investigate if the decrease in absolute lymphocyte count (ALC) from baseline during DMF treatment is associated with clinical and magnetic resonance imaging (MRI) disease activity. A secondary aim was to evaluate ALC variations over time in a real-life cohort of DMF-treated patients. METHODS Demographic, laboratory, clinical and MRI data were collected in this observational multicentre study, conducted on RRMS patients treated with DMF for at least 6 months. Multivariate Cox models were performed to evaluate the impact of 6-month ALC drop on time to no evidence of disease activity (NEDA-3) status loss. NEDA-3 is defined as absence of clinical relapses, MRI disease activity and confirmed disability progression. RESULTS In all, 476 patients (312 females, age at DMF start 38.4 ± 9.97 years) were analysed up to 5-year follow-up. A greater lymphocyte decrease was associated with a lower risk of NEDA-3 status loss (hazard ratio 0.87, P = 0.01). A worse outcome in patients with lower ALC drop (<11.5%), compared with higher tertiles (11.5%-40.5% and >40.5%), was observed (P = 0.008). The nadir of ALC drop (-33.6%) and 35% of grade III lymphopaenia cases occurred after 12 months of treatment. CONCLUSION A higher lymphocyte count drop at 6 months is related to better outcomes in DMF-treated patients. A careful ALC monitoring should be pursued up to 24 months of treatment.

Abstract
INTRODUCTION In recent years, many treatment options have become available for relapsing remitting MS. Randomized clinical trials and real-world studies are complementary sources of information, and together have the potential to offer a comprehensive understanding of the safety and efficacy profiles of each drug, a critical factor for a personalized management of the disease. AREAS COVERED In this review, the authors provide an up-to-date review of both RCTs and real-world studies assessing the safety and efficacy profiles of recently developed disease-modifying drugs for relapsing remitting MS. These include fingolimod, teriflunomide, dimethyl fumarate, alemtuzumab and ocrelizumab. EXPERT OPINION From the authors' review of the literature, the efficacy profiles resulted from RCTs were confirmed by observational studies with regard to the disease-modifying drugs considered. The magnitude of the effects on annualized relapse rates and MRI active lesions was generally even larger in the observational studies compared to RCTs. From the safety point of view, observational studies revealed new adverse events, mostly in the area of bacterial and opportunistic infections, not seen in the relative registration programme. This is a very important gain because it allows to elaborate appropriate strategies to prevent and handle the risks.

Abstract
BACKGROUND The safety profile of dimethyl fumarate (DMF) for multiple sclerosis (MS) is not fully understood. OBJECTIVE To systematically review the literature for adverse events (AE) associated with DMF for MS. METHODS We searched MEDLINE, EMBASE, CINAHL, Web of Science, CENTRAL, and clinicaltrials.gov for articles published from database inception to May/2019. Studies (observational and randomized controlled trials (RCTs)) reporting AEs, serious AEs (SAE), or discontinuation due to AEs were included. We summarized the proportion of DMF-exposed patients affected and calculated the risk ratios (RR) and number needed to treat for an additional harmful outcome (NNTH) and 95% confidence intervals (CI) for the DMF relative to placebo-exposed participants. RCT findings were pooled via meta-analyses. RESULTS Twenty-one observational studies, 4 RCTs, 1 RCT extension study, and 2 open-label studies were included, totalling 12,380 MS patients on DMF followed for an average of 19.8 months. Compared to placebo, DMF-exposed patients had a higher risk of grade III/IV lymphopenia (NNTH = 28.8;95%CI:20.2-50.5), pruritus (NNTH = 22.1;95%CI:14.0-52.3), flushing (NNTH = 3.7;95%CI:3.3-4.1), gastrointestinal related events (NNTH = 5.7;95%CI:3.5-15.7), nausea (NNTH = 23.4;95%CI:14.9-54.7), diarrhea (NNTH = 21.2;95%CI:13.6-47.6), and abdominal pain (NNTH = 19.2;95%CI:12.9-37.9). Patients discontinued DMF because of GI symptoms (498/5619;8.9%), lymphopenia (163/4003;4.1%), and flushing (173/4779;3.6%). From pooled analyses of 4 RCTs, AE risks were higher in the DMF versus placebo groups (RR = 1.37;95%CI:1.27-1.48), but SAEs were similar (RR = 1.01;95%CI:0.77-1.33). CONCLUSION Over the short-term, DMF was associated with a higher risk of AEs. The NNTH included 4 for flushing, 6 for gastrointestinal complaints, and 29 for severe or life-threatening (grade III/IV) lymphopenia. The longer-term safety of DMF, including consequences of lymphopenia remain unknown.

Abstract
The exact mechanism of action of different modifying treatments in the evolutionary course of multiple sclerosis (MS) remains unknown, but it is assumed that they act upon the cells involved in acquired immunity. One effect of these treatments is the development of lymphopenia, which carries inherent safety risks. This study was conducted to understand the alterations that teriflunomide (TERI) and dimethyl fumarate (DMF) exert upon white blood cells in a series of patients with MS. This study included a total of 99 patients; 44 treated with DMF and 55 patients treated with TERI. Blood counts were evaluated at baseline and every 6 months in order to track the absolute leukocyte, lymphocyte, and neutrophil counts. Twelve months after starting treatment, we observed a significant decrease in leukocytes (21.1%), lymphocytes (39.1%), and neutrophils (10%) in the DMF group. In the TERI group, leukocytes decreased by 11.1%, lymphocytes by 8.1%, and neutrophils by 15.7%. Both TERI and DMF produced a significant decrease in leukocytes during the first year of treatment and this was mainly related with a decrease in neutrophils in the TERI group and a decrease in lymphocytes in the DMF group.

Abstract
INTRODUCTION The portfolio of multiple sclerosis (MS) disease modifying treatments (DMTs) has significantly expanded over the past two decades. Given the lifelong use of MS pharmacotherapy, understanding their long-term safety profiles is essential in determining suitable and personalized treatment. AREAS COVERED In this narrative review, we summarize the short-, mid-, and long-term safety profile of currently available MS DMTs categories. In addition to the initial trial findings, safety outcomes derived from long-term extension studies (≥5-20 years) and safety-based prescription programs have been reviewed. In order to better understand the risk-benefit ratio for each particular DMT group, a short description of the DMT-based efficacy outcomes has been included. EXPERT OPINION Long-term extension trials, large observational studies and real-world databases allow detection of rare and potentially serious adverse events. Two-year-long trials are unable to fully capture the positive and negative effects of immune system modulation and reconstitution. DMT-based monitoring programs can provide greater insights regarding safe use of MS medications in different patient populations and clinical settings. During the process of shared DMT decision, both MS care providers and their patients should be aware of an ever-expanding number of drug-based adverse events and their influence on the risk-benefit analysis.
