Frequency of Dimethyl Fumarate-Induced Lymphopenia among Omani Patients with Multiple Sclerosis. Sultan Qaboos Univ Med J 2024; 24:44-51. [PMID: 38434464 PMCID: PMC10906776 DOI: 10.18295/squmj.9.2023.051] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2023] [Revised: 07/24/2023] [Accepted: 08/22/2023] [Indexed: 03/05/2024] Open
Abstract
Objectives Dimethyl fumarate (DMF) is known to cause lymphopenia when used to treat patients with multiple sclerosis (MS). However, research on DMF therapy in the Arab world, especially in Oman, is scarce. This study aimed to analyse the prevalence of lymphopenia among Omani patients with MS and their reasons for discontinuing DMF therapy. Methods In this retrospective study, the medical records of Omani patients with MS who were treated using DMF at two tertiary hospitals in Muscat, Oman, from February 2017 to February 2023 were reviewed. Their demographic, clinical and laboratory data were retrieved and analysed. Absolute lymphocyte count values at baseline and at the last follow-up, as well as the reasons for discontinuing DMF therapy, were collected. Descriptive and inferential statistical techniques were used for data analysis. Binary-logistic regression analysis was used to identify the risk factors for DMF-induced lymphopenia. Results A total of 64 Omani patients with MS were included in this study. The majority of the study participants (n = 40; 63%) were female. All included patients started DMF therapy at the mean age of 33 ± 7.7 years. After administration of DMF, 14 (21.9%) patients developed grades 1-3 of lymphopenia. The DMF therapy was discontinued for 23 (36.0%) patients, mainly in response to adverse events or confirmed pregnancy. Female gender was the only significant predictor of DMF-induced lymphopenia (P = 0.037). Conclusions Most Omani patients with MS had mild lymphopenia (grades 1-2). Early adverse events and pregnancy were the main reasons provided for discontinuing DMF therapy.

Abstract
BACKGROUND Adherence is a prerequisite for the efficacy of any drug, and previous studies have shown that non-adherence is associated with disease activity and increased health care cost in multiple sclerosis (MS). The aim of this study was to investigate rates and reasons for discontinuation of dimethyl fumarate (DMF) among people with MS on a national level and differences between clinics in Denmark. METHODS This was a nationwide, registry and population study of patients treated with DMF. We calculated standard residuals (SR) demonstrate differences between clinics. For survival analysis regarding discontinuation rates and discontinuation due to specific AEs we used log-rank test Cox-proportional hazards and plotted Kaplan-Meier graphics. RESULTS We included 2,448 people with MS, treated with DMF from 2013 to 2020. Average treatment duration was 26 months (5,382 treatment years). 49.2 % of patients who initiated treatment with DMF (n = 1205) were continuously treated. Reasons for discontinuation were adverse events (54.5 %, n = 656), active disease (26.1 %, n = 315), pregnancy (9.4 %, n = 113) or other reasons (13.2 %, n = 159). We compared SR to the mean regarding reasons for discontinuation and found significant differences between sites regarding gastrointestinal adverse events, flushing and lymphopenia. Discontinuation due to all adverse events, flushing and lymphopenia were more frequent in female than male patients. CONCLUSION In this population-based study, we found major differences between the MS clinics in rates and reason for discontinuation of DMF. Our results suggest that management strategies during DMF treatment can reduce discontinuation rates.

Abstract
In the area of drug discovery, repurposing strategies represent an approach to discover new uses of approved drugs besides their original indications. We used this approach to investigate the effects of dimethyl fumarate (DMF), a drug approved for relapsing-remitting multiple sclerosis and psoriasis treatment, on early injury associated with diabetic retinopathy (DR). We used an in vivo streptozotocin (STZ)-induced diabetic rat model. Diabetes was induced by a single injection of STZ in rats, and after 1 week, a group of animals was treated with a daily intraperitoneal injection of DMF or a vehicle. Three weeks after diabetes induction, the retinal expression levels of key enzymes involved in DR were evaluated. In particular, the biomarkers COX-2, iNOS, and HO-1 were assessed via Western blot and immunohistochemistry analysis. Diabetic rats showed a significant retinal upregulation of COX-2 and iNOS compared to the retina of normal rats (non-diabetic), and an increase in HO-1 was also observed in the STZ group. This latter result was due to a mechanism of protection elicited by the pathological condition. DMF treatment significantly induced the retinal expression of HO-1 in STZ-induced diabetic animals with a reduction in iNOS and COX-2 retinal levels. Taken together, these results suggested that DMF might be useful to counteract the inflammatory process and the oxidative response in DR. In conclusion, we believe that DMF represents a potential candidate to treat diabetic retinopathy and warrants further in vivo and clinical evaluation.

Abstract
Dimethyl fumarate (DMF) is a well-characterized molecule that exhibits immuno-modulatory, anti-inflammatory, and antioxidant properties and that is currently approved for the treatment of psoriasis and multiple sclerosis. Due to its Nrf2-dependent and independent mechanisms of action, DMF has a therapeutic potential much broader than expected. In this comprehensive review, we discuss the state-of-the-art and future perspectives regarding the potential repurposing of DMF in the context of chronic inflammatory diseases of the intestine, such as inflammatory bowel disorders (i.e., Crohn's disease and ulcerative colitis) and celiac disease. DMF's mechanisms of action, as well as an exhaustive analysis of the in vitro/in vivo evidence of its beneficial effects on the intestine and the gut microbiota, together with observational studies on multiple sclerosis patients, are here reported. Based on the collected evidence, we highlight the new potential applications of this molecule in the context of inflammatory and immune-mediated intestinal diseases.

Real-World Analysis Affirms the High Persistence and Adherence Observed with Diroximel Fumarate in Patients with Multiple Sclerosis. Neurol Ther 2023; 12:145-159. [PMID: 36334241 PMCID: PMC9837354 DOI: 10.1007/s40120-022-00413-0] [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] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/18/2022] [Accepted: 10/14/2022] [Indexed: 11/06/2022] Open
Abstract
INTRODUCTION Adherence to disease-modifying therapies is key for achieving optimal outcomes in multiple sclerosis (MS). Diroximel fumarate (DRF) is an oral fumarate approved for treatment of relapsing forms of MS. It has the same pharmacologically active metabolite as dimethyl fumarate (DMF) and similar efficacy and safety profiles, but with demonstrated fewer gastrointestinal (GI) related adverse events (AEs). There are limited data characterizing persistence and adherence to DRF in the real world. METHODS This retrospective analysis of the AcariaHealth Specialty Pharmacy Program included patients with MS initiating DRF from 1 December 2019 to 30 January 2021. This analysis evaluated persistence, measured as proportion of patients remaining on therapy; discontinuation rate due to GI AEs; and adherence measured by proportion of days covered (PDC). RESULTS Overall, 1143 patients were included; 433 (37.9%) patients had been treated with prior DMF and switched to DRF. Persistence was high in both groups: the estimated proportion of patients remaining on DRF at 16 months was 82.3% [95% confidence internal (CI) 77.2-86.3%], and 90.1% (95% CI 82.2-94.6%) in the DMF to DRF group. Fifty-two (4.5%) patients overall and 15 (3.5%) in the DMF switch subgroup discontinued DRF due to GI AEs. Mean PDC was 90.8% (95% CI 89.2-92.5%), and 85.4% (95% CI 83.3-87.4%) of patients achieved PDC ≥ 80% in the overall population. In the DMF to DRF group, mean PDC was 90.7% (95% CI 88.0-93.5%), and 84.8% (95% CI 81.4-88.1%) of patients achieved PDC ≥ 80%. CONCLUSION In this analysis of > 1000 patients treated with DRF in real-world clinical practice, overall persistence at 16 months was high, treatment discontinuation due to GI AEs was low, and patients were highly adherent to therapy. Of 433 patients who switched from DMF to DRF, most (> 90%) were able to tolerate and persist on DRF after switching. Graphical abstract available for this article.

Abstract
Dimethyl fumarate (DMF) is a small molecule currently approved and used in the treatment of psoriasis and multiple sclerosis due to its immuno-modulatory, anti-inflammatory, and antioxidant properties. As an Nrf2 activator through Keap1 protein inhibition, DMF unveils a potential therapeutical use that is much broader than expected so far. In this comprehensive review we discuss the state-of-art and future perspectives regarding the potential repositioning of this molecule in the panorama of eye pathologies, including Age-related Macular Degeneration (AMD). The DMF's mechanism of action, an extensive analysis of the in vitro and in vivo evidence of its beneficial effects, together with a search of the current clinical trials, are here reported. Altogether, this evidence gives an overview of the new potential applications of this molecule in the context of ophthalmological diseases characterized by inflammation and oxidative stress, with a special focus on AMD, for which our gene-disease (KEAP1-AMD) database search, followed by a protein-protein interaction analysis, further supports the rationale of DMF use. The necessity to find a topical route of DMF administration to the eye is also discussed. In conclusion, the challenge of DMF repurposing in eye pathologies is feasible and worth scientific attention and well-focused research efforts.

Abstract
Amaç: Çalışmamızda dimetil fumarat (DMF) kullanan ya da daha önce kullanmış olan ataklı multipl skleroz (MS) hastalarında etkinlik ve güvenlik verilerinin elde edilmesi amaçlandı.
Yöntem: Çalışma gözlemsel retrospektif kohort çalışması olarak tasarlandı. İstanbul Tıp Fakültesi Nöroloji Ana Bilim Dalında takip edilen ve 2014–2021 yılları arasında DMF kullanmış ataklı yineleyici (RRMS) ve ataklı progresif (RPMS) MS hastalarının verileri incelendi. Hastalarda DMF başlandıktan sonraki ilk genişletilmiş özürlülük durum ölçeği (EDSS) kötüleşmesi, ilk atak ve ilk yeni MRG lezyonu bilgileri elde edilerek hastalık aktivitesi olmaması durumu (NEDA-3) belirlendi.
Bulgular: Toplam 126 ataklı MS hastası (85 kadın, 41 erkek; 116 RRMS, 10 RPMS) çalışmaya dahil edildi. DMF öncesi başka bir tedavi kullanmış olan, ataklı progresif olan ve DMF öncesi hastalık süresi daha uzun olan hastalarda DMF daha yüksek oranda kesilmişti (p=0,002, p=0,03 ve p=0,002). Beyin MRG bilgisi olan 65 RRMS ve RPMS tanılı hastanın %25’inde DMF başlandıktan sonraki takip döneminde NEDA-3 durumu sağlandığı görüldü. DMF öncesinde EDSS skorunun 3’ün altında olması NEDA-3 durumunun yitimine, ilk atağa ve ilk özürlülük birikiminin olmasına kadar geçen süreleri anlamlı ölçüde uzattı (NEDA-3 için p=0,008, HR=1,95).
Sonuç: Çalışmamızda elde edilen gerçek yaşam verileri güncel bilgiler ile büyük oranda benzerlik göstermektedir. Elde ettiğimiz bulgular EDSS skoru 3’ün altında olan hastalarda başlanan DMF’nin atak, yeni beyin MRG lezyonu ve engellilik birikimi gelişme riskinin azalttığına işaret etmektedir.

Efficacy and Safety Outcomes with Diroximel Fumarate After Switching from Prior Therapies or Continuing on DRF: Results from the Phase 3 EVOLVE-MS-1 Study. Adv Ther 2022; 39:1810-1831. [PMID: 35211872 PMCID: PMC8870078 DOI: 10.1007/s12325-022-02068-7] [Citation(s) in RCA: 17] [Impact Index Per Article: 8.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2021] [Accepted: 12/07/2021] [Indexed: 02/06/2023]
Abstract
Introduction Diroximel fumarate (DRF) is an oral fumarate for relapsing multiple sclerosis (MS) with the same active metabolite as dimethyl fumarate (DMF). DRF has a safety/efficacy profile similar to DMF but with improved gastrointestinal (GI) tolerability and low (< 1%) treatment discontinuation due to GI adverse events (AEs). Efficacy and safety outcomes in patients who switched to DRF from other disease-modifying therapies (DMTs) have not been evaluated. Methods EVOLVE-MS-1 is an ongoing, 2-year, open-label, phase 3 study of DRF in adults with relapsing–remitting MS. Patients either entered as newly enrolled to DRF trials, or from the 5-week, randomized, head-to-head, phase 3 EVOLVE-MS-2 study of DRF and DMF. This analysis evaluated safety and GI tolerability in patients continuing on DRF (DRF-rollover) or switching from DMF (DMF-rollover) following EVOLVE-MS-2. Safety and efficacy were evaluated in a subset of newly enrolled patients who had received prior glatiramer acetate (GA; GA/DRF) or interferons (IFN; IFN/DRF) as their most recent DMT, prior to switching to DRF in EVOLVE-MS-1. Results As of September 1, 2020, 1057 patients were enrolled in EVOLVE-MS-1, including 166, 182, 239, and 225 patients in the GA/DRF, IFN/DRF, DRF-rollover, and DMF-rollover groups, respectively. Treatment discontinuation due to GI AEs was < 1% in all groups. GA/DRF and IFN/DRF patients experienced improvements from baseline in clinical and radiological efficacy outcomes, including significantly reduced annualized relapse rates. Rollover patients had low rates of new or recurrent GI AEs (DRF-rollover, 26.8%/4.2%; DMF-rollover, 27.1%/4.9%). Conclusion After 2 years of DRF exposure, patients with prior GA, IFN, or fumarate treatment had safety outcomes consistent with previous fumarate studies. Efficacy in patients with prior GA or IFN treatment was consistent with previous fumarate studies. The data suggest that transition to DRF from GA, IFN, or DMF is a reasonable treatment strategy, with low rates of discontinuation due to GI AEs. Trial Registration ClinicalTrials.gov (NCT02634307).

Abstract
Objectives: The aim of this study was to characterize multiple sclerosis (MS) patients exposed to dimethyl fumarate (DMF) and to evaluate the predictors of therapeutic response. In addition, the study offers a picture of how DMF use has changed over the past few years in naive or switcher patients. Methods: In this observational monocentric study, we examined the prescription flow of DMF in MS patients categorized as naive or switchers (for safety/tolerability, ineffectiveness, and de-escalation strategy) from 2015 to 2019. Clinical and magnetic resonance imaging data of DMF-treated patients were analyzed, and NEDA-3 status at 24 months was evaluated by the three assessment components (absence of clinical relapses, no Expanded Disability Status Scale progression, no radiological activity). Determinants of therapeutic response were also evaluated using regression analysis. Results: The sample included 595 MS patients exposed to DMF categorized as naive (158; 26.5%) and switchers for reasons of safety/tolerability (198; 33.3%), inefficacy (175; 29.4%), and de-escalation strategy (64; 10.8%). A 15% increase in DMF use in naive and horizontal shift groups was observed in the last 3 years of observation, whereas there was a drop, with prescription passed from ~20% to <5%, as an exit strategy from second-line therapies. NEDA-3 status was calculated for 340 patients after 24 months of DMF treatment and achieved in 188 (55.3%) of these. Analyzing the predictors of DMF response, we observed that lower annualized relapse rate (ARR) in 2 years pretreatment [hazard ratio (HR) = 0.49, p = 0.001] and being naive patients (HR = 1.38, p = 0.035) were associated with achievement of NEDA-3. Analogously, ARR in 2 years pretreatment affected the NEDA-3 achievement at 24 months in patients of the de-escalation group (HR = 0.07, p = 0.041), also indicating an effect related to the DMF initiation within 3 months (HR = 1.24, p = 0.029). Conclusion: Our findings confirm DMF as a handy drug with broad clinical utility, with greater benefits for naive patients and horizontal switchers. Additionally, an increase in the flow of DMF prescriptions in these two groups of patients was also observed in our cohort.

CNS Drugs 2021; 35:861-880. [PMID: 34319570 PMCID: PMC8354931 DOI: 10.1007/s40263-021-00842-9] [Citation(s) in RCA: 23] [Impact Index Per Article: 7.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 06/28/2021] [Indexed: 02/08/2023]
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
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
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
BACKGROUND Dimethyl fumarate (DMF) is an oral drug approved for Relapsing Multiple Sclerosis (RMS) patients. Grade III lymphopenia is reported in 5-10% DMF-treated patients. Data on lymphocyte count (ALC) recovery after DMF withdrawal following prolonged lymphopenia are still scarce. OBJECTIVES To characterize ALC recovery and to identify predictors of slower recovery after DMF interruption. METHODS Multicenter data from RMS patients who started DMF and developed lymphopenia during treatment were collected. In patients with grade II-III lymphopenia, ALCs were evaluated from DMF withdrawal until reaching lymphocyte counts > 800/mm3. RESULTS Among 1034 patients who started DMF, we found 198 (19.1%) patients with lymphopenia and 65 patients (6.3%) who discontinued DMF due to persistent grade II-III lymphopenia. Complete data were available for 51 patients. All patients recovered to ALC > 800 cells/mm3 with a median time of 3.4 months. Lower ALCs at DMF suspension (HR 0.98; p = 0.005), longer disease duration (HR 1.29; p = 0.014) and prior exposure to MS treatments (HR 0.03; p = 0.025) were found predictive of delayed ALC recovery. CONCLUSION ALC recovery after DMF withdrawal is usually rapid, nevertheless it may require longer time in patients with lower ALC count at DMF interruption, longer disease duration and previous exposure to MS treatments, potentially leading to delayed initiation of a new therapy.

Abstract
Background Delayed-released dimethyl fumarate (DMF) is an oral disease-modifying therapy (DMT) approved for treating patients with multiple sclerosis (MS). This post-marketing study aimed at collecting real-world data on the safety, effectiveness, and tolerability of DMF in patients with relapsing remitting multiple sclerosis (RRMS). Methods 1-year post-marketing survey of patients prescribed DMF followed-up quarterly in hospital setting and private neurological practices in Switzerland from January 2015 to January 2018. Data on relapses, Expanded disability status scale (EDSS) score change, safety, tolerability, treatment adherence as judged by the treating neurologist and satisfaction were collected. Patients could refer to a patient support program. Results Of the 158 patients, 67 (42.4%) were treatment naïve, 91 (57.6%) switched from a prior MS DMT to DMF, 131 (82.9%) were treatment adherent, 108 (68.4%) used the support program, and 45 (28.5%) discontinued the therapy. Insufficient tolerability and insufficient effectiveness were the main reasons for discontinuation. 134 (84.8%) patients remained relapse free, 97 (61.4%) had stable or decreased EDSS score after 12 months. 74 (46.8%) patients reported adverse events; of these, 28 (17.7%) discontinued DMF treatment. Physicians and patients rated treatment satisfaction similarly (median score 8.0 of 10). Conclusions The results obtained from this real-world observation are consistent with the efficacy and safety findings reported in pivotal and larger observational trials evaluating DMF treatment. Most side effects were experienced early after therapy initiation reflecting the timing of therapy discontinuation.

Effectiveness of Dimethyl Fumarate in Real-World Clinical Practice and Strategy to Minimize Adverse Effects and Use of Healthcare Resources. Patient Prefer Adherence 2021; 15:149-158. [PMID: 33542621 PMCID: PMC7853639 DOI: 10.2147/ppa.s284425] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/08/2020] [Accepted: 01/14/2021] [Indexed: 12/24/2022] Open
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 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
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
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
BACKGROUND Worldwide multiple sclerosis (MS) centers have coordinated their efforts to use data acquired in clinical practice for real-world observational studies. In this retrospective study, we aim to harmonize outcome measures, and to evaluate their heterogeneity within the Rising Italian Researchers in MS (RIReMS) study group. METHODS RIReMS members filled in a structured questionnaire evaluating the use of different outcome measures in clinical practice. Thereafter, thirty-four already-published papers from RIReMS centers were used for heterogeneity analyses, using the DerSimonian and Laird random-effects method to compute the between-study variance (τ2). RESULTS Based on questionnaire results, we defined basic modules for diagnosis and follow-up, consisting of outcome measures recorded by all participating centers at the time of diagnosis, and, then, at least annually; we also defined more detailed/optional modules, with outcome measures recorded less frequently and/or in the presence of specific clinical indications. Looking at heterogeneity, we found 5-year variance in age at onset (ES=27.34; 95%CI=26.18, 28.49; p<0.01; τ2=4.76), and 7% in female percent (ES=66.42; 95%CI=63.08, 69.76; p<0.01; τ2=7.15). EDSS variance was 0.2 in studies including patients with average age <36.1 years (ES=1.96; 95%CI=1.69, 2.24; p<0.01; τ2=0.19), or from 36.8 to 41.1 years (ES=2.70; 95%CI=2.39, 3.01; p<0.01; τ2=0.18), but increased to 3 in studies including patients aged >41.4 years (ES=4.37; 95%CI=3.40, 5.35; p<0.01; τ2=2.96). The lowest variance of relapse rate was found in studies with follow-up duration ≤2 years (ES=9.07; 95%CI=5.21, 12.93; p = 0.02; τ2=5.53), whilst the lowest variance in EDSS progression was found in studies with follow-up duration >2 years (ES=5.41; 95%CI=3.22, 7.60; p = 0.02; τ2=1.00). DISCUSSION We suggest common sets of biomarkers to be acquired in clinical practice, that can be used for research purposes. Also, we provide researchers with specific indications for improving inclusion criteria and data analysis, ultimately allowing data harmonization and high-quality collaborative studies.

Abstract
OBJECTIVES The aim of this study was to evaluate postmarketing dimethyl fumarate (DMF) safety and effectiveness in a real-world population with relapsing-remitting multiple sclerosis (RRMS). METHODS This was a retrospective, single-center study with RRMS patients treated with DMF. Demographic, clinical, and imagiological characteristics were analyzed, including annualized relapse rate (ARR), Expanded Disability Status Scale, "No Evidence of Disease Activity 3," previous treatment, adverse events, treatment duration, and reason for discontinuation. We investigated which baseline variables were associated with clinical and radiological outcomes. RESULTS We included 176 patients (70.4% females) with a median on-treatment follow-up time of 25.5 months. In total, 139 patients received prior disease-modifying therapies, and 37 were treatment-naive. Annualized relapse rate decreased by 77.1% in the total population (P < 0.001) and also decreased in the naive, tolerability switch, and efficacy switch groups by 95.8%, 56.7%, and 76.6% (P < 0.001). No Evidence of Disease Activity 3 status after 12 months of DMF treatment was maintained in 69.2% patients. Thirty patients (17%) discontinued treatment because of adverse drug reactions, and 21 (11.9%) because of lack of effectiveness. The occurrence of first relapse during follow-up was associated with higher ARR in the year before DMF start (hazard ratio, 4.833; P < 0.001) and prior exposure to multiple sclerosis treatments (tolerability and efficacy switchers). CONCLUSIONS In this real-world audit, DMF appeared to be effective and safe for RRMS. Additionally, the study suggested that naive patients strongly benefit from DMF, and DMF also improves ARR in patients who switched from injectable therapies due to tolerability and efficacy issues.

Abstract
BACKGROUND Dimethyl fumarate (DMF) tolerability and safety in multiple sclerosis (MS) has been analyzed in randomized clinical trials. Real-life studies are needed to assess possible harms of this therapy in a wider MS population. OBJECTIVE To evaluate DMF tolerability, safety and persistence in MS in a real-world setting. METHODS We conducted a multicenter prospective study of patients who started DMF, attended in 16 public hospitals of Spain. A specific database was elaborated to collect data on most frequent adverse events (AE). Regression models were used to analyze the effect of demographic and clinical characteristics on risk of AEs and DMF discontinuation. RESULTS We collected data of 886 patients (2681 patients/years-exposition) with median 39.5 (IQR 23, 51.5) months on DMF exposure; 25.3% were treatment naïve and 74.7% switched to DMF from other disease-modifying therapies. DMF was discontinued in 29.9% of patients, in 13.2% due to AEs and in 13.5% to inefficacy. AEs were experienced by 71.2%, being flushing the most frequent (44.1%), 5.4% developed grade III lymphopenia, without cases of grade IV. Females showed a higher risk of flushing and gastroenteric symptoms (OR 1.49, p = 0.011; OR 1.69, p = 0.001, respectively); lymphopenia was associated with older age (OR 1.04, p < 0.001), and a higher EDSS with lymphopenia (OR 1.10, p = 0.035) and DMF withdrawal (HR 1.43, p = 0.012). No safety problems were reported. CONCLUSIONS Our findings confirm good tolerability and safety of DMF in real-world setting and suggest that women have an increased risk of AEs and higher baseline disability involves greater risk of drug discontinuation.

Abstract
Dimethyl fumarate (Tecfidera®) is approved for the treatment of relapsing forms of multiple sclerosis (MS). Based on evidence from the clinical trial and real-world settings, dimethyl fumarate is an effective treatment in this patient population, with benefits maintained over the longer term. In the pivotal, placebo-controlled phase III DEFINE and CONFIRM trials in adults with relapsing-remitting multiple sclerosis (RRMS), twice-daily dimethyl fumarate reduced clinical relapse and MRI measures of disease activity and improved some aspects of health-related quality of life (HR-QoL). Reduced disability progression was also observed with dimethyl fumarate in DEFINE. Results in predominantly East Asian patients (APEX trial) were reflective of those seen in DEFINE and CONFIRM. Dimethyl fumarate had an acceptable tolerability profile. The most common adverse events were flushing and gastrointestinal events, which were of mild or moderate severity and appear to be largely manageable. Thus twice-daily dimethyl fumarate remains an effective treatment option for use in patients with RRMS, with the convenience of oral administration.

Abstract
We often see that clinical and demographic characteristics of real-world studies (RWS) do not differ from patients included in randomized controlled trials (RCT). OBJECTIVE to compare clinical and demographic aspects of patients included in RCT and RWS that evaluated new disease modifying treatment in multiple sclerosis (MS). METHODS a systematic non-language-restricted literature search of RCT and RWS that evaluated new disease modifying treatments (natalizumab, alemtuzumab, ocrelizumab, fingolimod, teriflunomide, dimethyl fumarate and cladribine) from January 2005 to January 2019. Demographic and clinical data were extracted, described and compared. RESULTS 18 RCT and 73 RWS were included. We found no differences in clinical and demographic aspects between RCT and RWS except in the frequency of naïve patients included in RCT vs. RWS 65.6% (95%CI 52-74) vs. 36.4% (95%CI 21-46), respectively, (p = 0.013) at study entry, as well as for the inclusion of patients that used previous treatment 34.4% (95%CI 22-41) vs. 63.6% (95%CI 53-74) in RCT and RWS, respectively,(p = 0.007) at study entry. CONCLUSION We did not observe significant differences in most clinical and demographic aspects of included patients in RCT and RWS. Studies that include the full spectrum of MS patients followed in clinical practice are needed.

Abstract
Multiple sclerosis (MS) is the most common neurological immune-mediated disease leading to disability in young adults. The outcome of the disease is unpredictable, and over time, neurological disabilities accumulate. Interferon beta-1b was the first drug to be approved in the 1990s for relapsing-remitting MS to modulate the course of the disease. Over the past two decades, the treatment landscape has changed tremendously. Currently, more than a dozen drugs representing 1 substances with different mechanisms of action have been approved (interferon beta preparations, glatiramer acetate, fingolimod, siponimod, mitoxantrone, teriflunomide, dimethyl fumarate, cladribine, alemtuzumab, ocrelizumab, and natalizumab). Ocrelizumab was the first medication to be approved for primary progressive MS. The objective of this review is to present the modes of action of these drugs and their effects on the immunopathogenesis of MS. Each agent's clinical development and potential side effects are discussed.

Discontinuation of teriflunomide and dimethyl fumarate in a large Italian multicentre population: a 24-month real-world experience. J Neurol 2018; 266:411-416. [PMID: 30515629 DOI: 10.1007/s00415-018-9144-9] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2018] [Revised: 11/07/2018] [Accepted: 11/26/2018] [Indexed: 01/04/2023]
Abstract
BACKGROUND Teriflunomide (TRF) and Dimethyl fumarate (DMF) are licensed drugs for relapsing-remitting Multiple Sclerosis (RRMS). OBJECTIVES We aimed to compare the rate and the time to discontinuation among persons with RRMS (pwRRMS), newly treated with TRF and DMF. MATERIALS AND METHODS A retrospective study on prospectively collected data was performed in nine tertiary MS centers, in Italy. The 24-month discontinuation rate in the two cohorts was the primary study outcome. We also assessed the time to discontinuation and reasons of therapy withdrawn. Discontinuation of TRF and DMF was defined as a gap of treatment ≥ 60 days. RESULTS A cohort of 903 pwRRMS (316 on TRF and 587 on DMF) was analyzed. During 24 months of follow-up, pwRRMS on TRF and DMF showed similar discontinuation rates. The analysis of predictors with Cox regression model showed differences between the two groups (p for log-rank test = 0.007); male gender [HR 2.21 (1.00-4.90); p = 0.01] and the number of previous switches [HR 1.47 (1.16-1.86); p = 0.01] were associated with higher hazard of discontinuation in the DMF group. CONCLUSIONS In a real-world setting, pwRRMS on TRF and DMF had similar discontinuation rates over 24 months. Male pwRRMS on DMF with a previous history of therapeutic failure are at more risk of discontinuation therapy.
