Effectiveness, safety and health-related quality of life of multiple sclerosis patients treated with fingolimod: results from a 12-month, real-world, observational PERFORMS study in the Middle East

Therapeutic Potential of Fingolimod on Psychological Symptoms and Cognitive Function in Neuropsychiatric and Neurological Disorders

Neuropsychiatric and neurological disorders pose a significant global health burden, highlighting the need for innovative therapeutic approaches. Fingolimod (FTY720), a common drug to treat multiple sclerosis, has shown promising efficacy against various neuropsychiatric and neurological disorders. Fingolimod exerts its neuroprotective effects by targeting multiple cellular and molecular processes, such as apoptosis, oxidative stress, neuroinflammation, and autophagy. By modulating Sphingosine-1-Phosphate Receptor activity, a key regulator of immune cell trafficking and neuronal function, it also affects synaptic activity and strengthens memory formation. In the hippocampus, fingolimod decreases glutamate levels and increases GABA levels, suggesting a potential role in modulating synaptic transmission and neuronal excitability. Taken together, fingolimod has emerged as a promising neuroprotective agent for neuropsychiatric and neurological disorders. Its broad spectrum of cellular and molecular effects, including the modulation of apoptosis, oxidative stress, neuroinflammation, autophagy, and synaptic plasticity, provides a comprehensive therapeutic approach for these debilitating conditions. Further research is warranted to fully elucidate the mechanisms of action of fingolimod and optimize its use in the treatment of neuropsychiatric and neurological disorders.

A Prospective, Observational Study Assessing Effectiveness, Safety, and QoL of Greek Patients with Multiple Sclerosis Under Treatment with Fingolimod

INTRODUCTION

Fingolimod is the first approved oral therapy for relapsing-remitting multiple sclerosis (RRMS). The present study aimed to further characterize fingolimod's safety profile, and to assess the patient-reported treatment satisfaction and impact of fingolimod on the quality of life (QoL) of patients with multiple sclerosis (MS) treated in routine care in Greece.

METHODS

This was a multicenter, prospective, observational, 24-month study conducted in Greece by hospital-based and private practice neurologists who specialize in MS. Eligible patients had initiated fingolimod within 15 days in accordance with the locally approved label. Safety outcomes included any adverse event (AE) observed during the study period and efficacy outcomes included both objective (disability progression and 2-year annualized relapse rate) and patient-reported assessments (Treatment Satisfaction Questionnaire for Medication (TSQM) v1.4 and the EuroQol (EQ)-5-dimension (5D) 3-level instruments).

RESULTS

A total of 489 eligible patients (age 41.2 ± 9.8 years; 63.7% female; 4.2% treatment-naive) were exposed to fingolimod for a median of 23.7 months. During the observation period, 20.5% of the participants experienced 233 AEs. Lymphopenia (8.8%), leukopenia (4.2%), hepatic enzyme increased (3.4%), and infections (3.0%) were the most common. Most patients (89.3%) did not experience disability progression; the 2-year annualized relapse rate decreased by 94.7% compared to baseline. The median EQ-visual analogue scale (VAS) was 74.5 at month 24 vs. 65.0 at enrollment (p < 0.001) and the EQ-5D index score was 0.80 vs. 0.78, respectively. Significant improvements were noted in the TSQM global satisfaction and effectiveness domain scores between 6 and 24 months post enrollment (median scores at month 24, 71.4 and 66.7, respectively) (p < 0.001). Significant increases from enrollment to the 24th month were also noted in the patients' global satisfaction and effectiveness domain scores [mean change of 7.4 ± 17.7 (p = 0.005) and mean increase of 5.4 ± 16.2) (p = 0.043), respectively].

CONCLUSION

In the real-world setting of Greece, fingolimod demonstrates a clinical benefit and a predictable and manageable safety profile, which contribute towards high patient-reported treatment satisfaction and improvements in the QoL of patients with MS.

Retrospective analysis of effectiveness of fingolimod in real life setting in Turkey (REFINE)

BACKGROUND

During multiple sclerosis (MS) treatment different modes of action such as lateral (interferon beta to glatiramer acetate or glatiramer acetate to interferon beta) or vertical (interferon beta/glatiramer acetate to fingolimod) drug switch can be performed. This study aims to investigate the clinical effectiveness of switching from the first-line injectable disease modifying treatments (iDMTs) to fingolimod (FNG) compared to switching between first-line iDMTs.

METHODS

This is a multicenter, observational and retrospective study of patients with relapsing-remitting MS who had lateral and vertical switch. The observation period included three key assessment time points (before the switch, at switch, and after the switch). Data were collected from the MS patients' database by neurologists between January 2018 and June 2019. The longest follow-up period of the patients was determined as 24 months after the switch.

RESULTS

In 462 MS patients that were included in the study, both treatments significantly decreased the number of relapses during the postswitch 12 months versus preswitch one year while patients in the FNG group experienced significantly fewer relapses compared to iDMT cohort in the postswitch 12 months period. FNG cohort experienced fewer relapses than in the iDMT cohort within the postswitch 2 year. The mean time to first relapse after the switch was significantly longer in the FNG group.

DISCUSSION

The present study revealed superior effectiveness of vertical switch over lateral switch regarding the improvement in relapse outcomes. Patients in the FNG cohort experienced sustainably fewer relapses during the follow-up period after the switch compared the iDMT cohort. Importantly, switching to FNG was more effective in delaying time to first relapse when compared with iDMTs.

Ceramide and Sphingosine-1-Phosphate in Neurodegenerative Disorders and Their Potential Involvement in Therapy

Neurodegenerative disorders (ND) are progressive diseases of the nervous system, often without resolutive therapy. They are characterized by a progressive impairment and loss of specific brain regions and neuronal populations. Cellular and animal model studies have identified several molecular mechanisms that play an important role in the pathogenesis of ND. Among them are alterations of lipids, in particular sphingolipids, that play a crucial role in neurodegeneration. Overall, during ND, ceramide-dependent pro-apoptotic signalling is promoted, whereas levels of the neuroprotective spingosine-1-phosphate are reduced. Moreover, ND are characterized by alterations of the metabolism of complex sphingolipids. The finding that altered sphingolipid metabolism has a role in ND suggests that its modulation might provide a useful strategy to identify targets for possible therapies. In this review, based on the current literature, we will discuss how bioactive sphingolipids (spingosine-1-phosphate and ceramide) are involved in some ND (Alzheimer’s disease, Parkinson’s disease, amyotrophic lateral sclerosis) and their possible involvement in therapies.

Early use of fingolimod is associated with better clinical outcomes in relapsing-remitting multiple sclerosis patients

BACKGROUND

Multiple sclerosis (MS) is a chronic autoimmune disease with huge heterogeneity in terms of clinical course, disease severity and treatment response. The need for a tailored treatment approach has emerged over the last few years. The present observational study aims to assess fingolimod (FTY) effectiveness in RRMS patients, stratifying them according to the disease-modifying treatments used before FTY, to identify subjects who could benefit more from this treatment.

METHODS

We prospectively included 554 RRMS patients who started FTY at San Raffaele Hospital between 2012 and 2018. We classified them into three categories according to previous treatments: naïve patients, subjects previously treated with first-line drugs, and patients previously treated with second-line drugs. We compared disease activity during a 2-years follow-up using No-Evidence-of-Disease-Activity (NEDA-3) and Time-To-First-Relapse (TTFR) outcomes, applying logistic and Cox proportional hazard regression respectively.

RESULTS

The proportion of patients who maintained NEDA-3 status was higher in the naïve group despite a higher level of baseline disease activity (naïve versus first-line p = 0.025, naïve versus second-line p < 0.001). In the multivariable analyses, patients switching to FTY from first- and second-line treatments showed a higher risk of disease reactivation (p = 0.041, OR = 1.86 and p = 0.002, OR = 2.92, respectively) and a shorter TTFR (p = 0.017, HR = 4.35 and p = 0.001, HR = 8.19, respectively).

CONCLUSION

Naïve patients showed a better response to FTY compared to patients switching to FTY from other drugs. Our findings support the early use of FTY in patients with active MS.

Long-Term Effectiveness, Safety and Tolerability of Fingolimod in Patients with Multiple Sclerosis in Real-World Treatment Settings in France: The VIRGILE Study

Introduction

It is important to confirm the effectiveness and tolerability of disease-modifying treatments for relapsing–remitting multiple sclerosis (RRMS) in real-world treatment settings. This prospective observational cohort study (VIRGILE) was performed at the request of the French health authorities. The primary objective was to evaluate the effectiveness of fingolimod 0.5 mg in reducing the annualised relapse rate (ARR) in patients with RRMS.

Methods

Participating neurologists enrolled all adult patients with RRMS starting fingolimod treatment between 2014 and 2016, who were followed for 3 years. Follow-up consultations took place at the investigator’s discretion. The primary outcome measure was the change in ARR at month 24 after fingolimod initiation. Relapses and adverse events were documented at each consultation; disability assessment (EDSS) and magnetic resonance imagery were performed at the investigator’s discretion.

Results

Of 1055 eligible patients, 633 patients were assessable at month 36; 405 (64.0%) were treated continuously with fingolimod for 3 years. The ARR decreased from 0.92 ± 0.92 at inclusion to 0.31 ± 0.51 at month 24, a significant reduction of 0.58 [95% CI − 0.51 to − 0.65] relapses/year (p < 0.001). Since starting fingolimod, 461 patients (60.9%) remained relapse-free at month 24 and 366 patients (55.5%) at month 36. In multivariate analysis, no previous disease-modifying treatment, number of relapses in the previous year and lower EDSS score at inclusion were associated with a greater on-treatment reduction in ARR. The mean EDSS score remained stable over the course of the study. Sixty-one out of 289 (21.1%) patients presented new radiological signs of disease activity. Treatment-related serious adverse events were lymphopenia (N = 21), bradycardia (N = 19), elevated transaminases (N = 9) and macular oedema (N = 9).

Conclusions

The effectiveness and tolerability of fingolimod in everyday clinical practice are consistent with findings of previous phase III studies. Our study highlights the utility of fingolimod for the long-term management of patients with multiple sclerosis.

The Disease-Modifying Therapies of Relapsing-Remitting Multiple Sclerosis and Liver Injury: A Narrative Review

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.

Long-Term Effectiveness of Fingolimod for Multiple Sclerosis in a Real-World Clinical Setting

INTRODUCTION

The primary aim of the present study was to evaluate the long-term efficacy of fingolimod in patients with multiple sclerosis (MS); secondary aims were to describe the safety of fingolimod with the evaluation of treatment satisfaction and impact on the quality of life in real life.

METHODS

We collected clinical, demographical, neuroradiological, and treatment data, including pre- and posttreatment status health-related quality of life from 286 MS patients consecutively treated with fingolimod. Clinical assessment was based on the Expanded Disability Status Scale (EDSS), and quality of life assessment was performed with MS-related quality of life inventory (MSQOLI). The data were recorded at baseline and every 6 months for 2 years.

RESULTS

One hundred and fourteen males and 172 females were enrolled. The annualized relapse rate and EDSS showed a statistically significant reduction during the observation period (p < 0.001). The patients also demonstrated substantial improvements in magnetic resonance imaging (MRI) outcomes (p < 0.001). Health-related quality of life scores improved significantly between baseline and 24-month visit (p < 0.001). No serious adverse events occurred.

CONCLUSION

In our cohort, fingolimod treatment was associated with reduced relapse, MRI activity, and improved EDSS and MSQOLI scores. Additionally, fingolimod has been able to maintain its effectiveness over a considerable long period of treatment.

Safety of S1P Modulators in Patients with Immune-Mediated Diseases: A Systematic Review and Meta-Analysis

INTRODUCTION

Sphingosine-1-phosphate modulators are approved for the treatment of multiple sclerosis and are under development for other immune-mediated conditions; however, safety concerns have arisen.

OBJECTIVE

The objective of this systematic review was to investigate the safety profile of S1P modulators in patients with multiple sclerosis, ulcerative colitis, Crohn's disease, psoriasis, and systemic lupus erythematosus.

METHODS

We searched MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials from 1 January, 1990 through 1 April, 2020. We also performed a manual review of conference databases from 2017 through 2020. The primary outcome was the occurrence of adverse events and serious adverse events. We also estimated the occurrence of serious infections, herpes zoster infection, malignancy, bradycardia, atrio-ventricular block, and macular edema. We performed a meta-analysis of controlled studies to assess the risks of such events.

RESULTS

We identified 3843 citations; of these, 26 studies were finally included, comprising 9604 patients who were exposed to a sphingosine-1-phosphate modulator. A meta-analysis of randomized controlled trials showed an increased risk in herpes zoster infection [risk ratio, 1.75 (95% confidence interval 1.09-2.80)], bradycardia [2.64 (1.77-3.96)], and atrio-ventricular block [1.73 (1.03-2.91)] among subjects exposed to sphingosine-1-phosphate modulators as compared with a placebo or an active comparator.

CONCLUSIONS

We found an increased risk of herpes zoster infection, and transient cardiovascular events among patients treated with sphingosine-1-phosphate modulators.

Longitudinal analysis of safety and medication adherence of patients in the Fingolimod patient support program: a real-world observational study

The Fingolimod Patient Support Program (F-PSP) is an interprofessional specialty pharmacy service designed to ensure responsible use of fingolimod by promoting patient safety and medication adherence. This study aims to evaluate the safety and medication adherence of patients who joined the F-PSP between 2013 and 2016. Sociodemographic and medical characteristics, patient safety data (patient-reported symptoms, discontinuations due to adverse events (AEs), repeated first-dose monitoring), and medication adherence (implementation, persistence, reasons for discontinuation, influence of covariates, barriers and facilitators) were described. Sixty-seven patients joined the F-PSP. Patients reported a high frequency of symptoms. Due to AEs, 7 patients discontinued fingolimod, 3 took therapeutic breaks, and 1 reduced the regimen temporarily. Three patients repeated the first-dose monitoring. Patients had a high medication adherence over the 18-month analysis period: implementation decreased from 98.8 to 93.7%, and fingolimod persistence was 83.2% at 18 months. The patients’ level of education, professional situation, and living with child(ren) influenced implementation. Patients reported more facilitators of medication adherence than barriers. The F-PSP seems valuable for supporting individual patients (ensuring responsible use of fingolimod and inviting patients for shared-decision making) and public health (indirectly gathering real-world evidence).

Bioequivalence Study of 2 Capsule Formulations of Fingolimod 0.5 mg Assessing Both Parent Drug and Active Metabolite in New Zealand Healthy Subjects (Truncated Design)

Fingolimod is indicated for the treatment of patients with the relapsing-remitting form of multiple sclerosis. The primary study objective was to evaluate the bioequivalence of a test formulation, 0.5 mg fingolimod HCl capsule (Lebrina, Asofarma Sociedad Anónima Industrial y Comercial, Argentina) relative to a reference formulation, 0.5 mg fingolimod capsule (Gilenya, Novartis Pharmaceutical, Australia). In a single-center, randomized, single-dose, single-blinded, 2-way crossover study, 33 New Zealand healthy subjects of both sexes were enrolled to receive a 0.5-mg dose of 3 capsules of each fingolimod formulation under fasting conditions, with a 42-day washout period between administrations. Additional pharmacokinetic information regarding its main active metabolite, fingolimod phosphate, was also provided. The point estimate and 90% confidence intervals of the ratios of maximum concentration and area under the plasma concentration-time curve from time 0 to 72 hours were 99.07 (95.83-102.41) and 97.64 (95.33-100.00) for fingolimod, and 95.60 (90.95-100.49) and 98.54 (96.19-100.96), for fingolimod phosphate. Primary parameters, maximum concentration and area under the plasma concentration-time curve from time 0 to 72 hours for fingolimod and fingolimod phosphate were found to have no significant difference when test and reference formulations were compared. Fingolimod and fingolimod phosphate of both formulations were within the accepted 90% confidence interval limits of 80.00% and 125.00%. No significant differences between the test and reference drug products were detected in any of the pharmacokinetic parameters estimated. Notwithstanding the primary conclusion of bioequivalence is focused on the measurement of the parent compound, compliance with the same criteria by the active metabolite reinforces the comparability between the pharmacokinetic profiles of both formulations (ClinicalTrials.gov Identifier: NCT03757338).

Effectiveness of fingolimod in real-world relapsing-remitting multiple sclerosis Italian patients: the GENIUS study

Background

Fingolimod is the first oral agent approved for treatment of relapsing-remitting multiple sclerosis (RRMS). We aimed to evaluate fingolimod effectiveness in a real-world sample of RRMS patients.

Methods

A retrospective, multicentre study in patients treated with fingolimod, whom clinical and radiological data were collected in the 2 years preceding and following the initiation of fingolimod.

Results

Out of 414 patients, 56.8% received prior first-line injectable disease-modifying therapies, 25.4% were previously treated with natalizumab, 1.2% with immunosuppressant agents, and 16.7% were treatment naive. The annualized relapse rate decreased by 65% in the first year and by 70% after two years of treatment. Age ≤ 40 years, ≥ 1 relapse in the 24 months before fingolimod initiation and previous treatment with natalizumab were risk factors for relapses. Overall, 67.9% patients had no evidence of disease activity (NEDA-3) after 1 year and 54.6% after 2 years of treatment. A higher proportion of naïve (81.2% in 1 year and 66.7% after 2 years) or first-line injected patients (70.2% and 56.6%) achieved NEDA-3 than those previously treated with natalizumab (54.3% and 42.9%).

Conclusions

Fingolimod appeared to be effective in naive patients and after first-line treatment failure in reducing risk of relapse and disease activity throughout the 2-year follow-up.

Macular oedema and changes in macular thickness in multiple sclerosis patients treated with fingolimod

Macular oedema is a known side effect to fingolimod, but changes in specific areas of the retina are only sparsely described. Our aim was to investigate the prevalence of macular oedema and characterize macular changes after initiation of fingolimod based on routine ophthalmological examinations in all consecutive patients treated at our hospital. We evaluated macular thickness change from baseline to 3-4 months after initiation of treatment. Central retinal thickness, total macular volume, total macular thickness, average thickness and inner-/outer macular thickness were automatically measured using optical coherence tomography (OCT). A total of 190 eyes completed the study, and none of those developed visible macular oedema. All macular areas showed a small, but statistically significant increase in thickness. Total macular volume increased by a mean of 0.05 mm³ (P = <.001). Mean best-corrected visual acuity only changed by .03 (P = .074). We observed a minimal change in macular thickness and no clinically relevant affection on visual acuity after 3-4 months of fingolimod treatment. Thus, our results do not underpin the need for routine screening for macular oedema in asymptomatic MS patients without diabetes or uveitis receiving 0.5 mg fingolimod daily.

Do clinical trials for new disease modifying treatments include real world patients with multiple sclerosis?

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.

[Influence of psychopathological factors and personality traits on the results of the study of quality of life in patients with multiple sclerosis]

AIM

To study the influence of psychopathological factors and personality traits on the results of the study of quality of life (QoL) in patients with multiple sclerosis (MS).

MATERIAL AND METHODS

Forty-three patients with relapsing MS were included in the study (74.4% female; mean age 33.1 years). SF-36 was used to evaluate QoL. Effects of psychopathological factors, cognitive regulation of emotions and personality traits on QoL were studied. Statistical analysis was performed using multiple linear model.

RESULTS AND DISCUSSION

A wide number of strategies of cognitive regulation of emotions has conflicting effects on the physical component of QoL; subscales of anhedonic depression and anxious arousal (MASQ), which probably represent depressive and anxiety disorders, decrease the physical component of QoL. The key factors of the mental component of QoL include psychopathological factors (mostly obsessive-compulsive symptoms) and personality traits (the more intense they are the lower is QoL). Strategies of cognitive regulation of emotions have low impact on the mental component of QoL.

Real-world experience of fingolimod in patients with multiple sclerosis (MS Fine): An observational study in the UK

Background

Fingolimod is approved for the treatment of highly active relapsing–remitting multiple sclerosis in Europe. There is limited information on its effectiveness and safety in clinical practice within the UK.

Objective

To evaluate retrospectively the effectiveness and safety of fingolimod in patients with relapsing–remitting multiple sclerosis who were prescribed fingolimod by UK neurologists within the National Health Service.

Methods

This was a multicentre, observational study conducted in the UK. Patients were initiated on fingolimod 0.5 mg 12 months before inclusion in the study. Key efficacy outcomes included annualised relapse rate and the proportion of patients free from relapses, disability progression and clinical and radiological disease activity at 12 months following fingolimod initiation. Resource utilisation and safety outcomes were also assessed.

Results

In 12 months of treatment with fingolimod, the mean annualised relapse rate was reduced by 79%, the majority of patients were free from relapses (83.7%). Based on limited data, most patients were free from disability progression and clinical and radiological disease activity. More than 90% of patients continued on fingolimod. Lymphocyte count reductions and liver enzyme increases were observed.

Conclusion

Fingolimod was effective in reducing the disease activity in relapsing–remitting multiple sclerosis patients requiring an escalation from first-line therapies who were prescribed fingolimod in clinical practice in the UK.

A randomized study to evaluate the effect of exercise on fatigue in people with relapsing-remitting multiple sclerosis treated with fingolimod

Background

Fatigue is a major symptom of multiple sclerosis (MS) in patients, and it has been shown to improve with physical exercise. Although fingolimod might lessen fatigue, it is unclear how patients treated with fingolimod react to physical activity regarding fatigue.

Objective

This study evaluated the effect of an exercise intervention on fatigue in relapsing–remitting MS patients receiving fingolimod.

Methods

People with MS (PwMS) were randomized to either a structured internet-based exercise program (e-training) or no e-training intervention. The primary endpoint was the change in the Modified Fatigue Impact Scale (mFIS) after six months.

Results

The primary analysis showed no statistically significant difference between groups in the mFIS change. Subgroup analyses revealed a beneficial effect of physical exercise for PwMS with low aerobic capacity and with low aerobic capacity plus more severe fatigue. The incidence of adverse events was similar in both groups. No cardiovascular events were reported. The majority of PwMS were relapse free.

Conclusion

Physical exercise benefits on fatigue may depend on the physical capacity of the patient and requires individualized training. Consistent with previous studies, these results suggest that physical exercise generally does not impose a risk and that this holds true also for patients receiving fingolimod.

Long-term safety and real-world effectiveness of fingolimod in relapsing multiple sclerosis

With a growing number of disease-modifying therapies becoming available for relapsing multiple sclerosis, there is an important need to gather real-world evidence data regarding long-term treatment effectiveness and safety in unselected patient populations. Although not providing as high a level of evidence as randomized controlled trials, and prone to bias, real-world studies from observational studies or registries nevertheless provide crucial information on real-world outcomes of a given therapy. In addition, evaluation of treatment satisfaction and impact on quality of life are increasingly regarded as complementary outcome measures. Fingolimod was the first oral disease-modifying therapy approved for relapsing multiple sclerosis. This review aims to summarize current knowledge on the long-term effectiveness and safety outcomes of multiple sclerosis patients on fingolimod. Impact on treatment satisfaction and quality of life will be discussed according to available data.
