Evaluation of the use of high-efficacy treatments (HETs) in patients with relapsing-remitting multiple sclerosis in Argentina. Mult Scler Relat Disord 2023; 79:104935.

Abstract
BACKGROUND Disease-modifying therapies (DMTs) in multiple sclerosis (MS) can be classified according to the efficacy in which they prevent inflammatory activity. To date, there are limited data regarding the use of high-efficacy treatments (HETs) in Latin America (LATAM). We aimed to analyze the use of HETs in Argentina, focusing on the clinical and sociodemographic characteristics of the patients who use these treatments and the changes in the trend of use over the years. METHODS A retrospective cohort study was done using the Argentina MS patient registry, RelevarEM. Patients diagnosed with relapsing-remitting MS (RRMS) according to validated diagnostic criteria and under treatment with natalizumab, alemtuzumab, cladribine, rituximab or ocrelizumab were included. RESULTS Out of 2450 RRMS patients under a DMT, 462 (19%) were on HETs. One third of those patients (35%) received HETs as the first treatment. The most frequent reason for switching to HETs was treatment failure to previous DMT (77%). The time from MS diagnosis to the first HET in treatment-naive patients was less than one year (IQR: 0-1 year) and in treatment-experienced patients it was 5 years (IQR: 3-9 years). Between 2015 and 2017 (P1), 729 patients included in RelevarEM started a new treatment, of which 85 (11.65%) were HETs. Between 2018 and 2020 (P2), 961 patients included in RelevarEM started a new treatment, of which 284 (29.55%) were HETs. When comparing P2 with P1, a significant increase in the use of HETs was observed (p < 0.01). The most frequently used HETs were alemtuzumab (50.59%) in P1, and cladribine (45.20%) in P2. CONCLUSION The demographic and clinical characteristics of patients under HET in Argentina were identified. Based on a real-world setting, we found a significant trend towards and a rapid increase in the use of HETs in clinical practice in patients with RRMS.

Abstract
OBJECTIVE Currently, there are several reasons to promote worldwide the concept of multiple sclerosis care units (MSCU) for a better management of affected patients. Ideally, the MSCU should have some human and technical resources that distinguish and improve the care of affected patients; however, local, and regional aspects should be considered when recommending how these units should operate. The objective of these consensus recommendations was to review how MSCU should work in Latin America to improve long-term outcomes in MS patients. METHODS A panel of neurology experts from Latin America dedicated to the diagnosis and care of MS patients gathered virtually during 2019 and 2020 to carry out a consensus recommendation about objectives and functioning implementation of MSCU in Latin America. To achieve consensus, the methodology of "formal consensus-RAND/UCLA method" was used. RESULTS Recommendations focused on the objectives, human and technical resources, and the general functioning that MSCU should have in Latin America. CONCLUSIONS The recommendations of these consensus guidelines attempt to optimize the health care and management of MS patients by setting how MSCU should work in our region.

Quality of Life Improves with Alemtuzumab Over 6 Years in Relapsing-Remitting Multiple Sclerosis Patients with or without Autoimmune Thyroid Adverse Events: Post Hoc Analysis of the CARE-MS Studies. Neurol Ther 2020; 9:443-457. [PMID: 32410147 PMCID: PMC7606412 DOI: 10.1007/s40120-020-00191-7] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/11/2019] [Indexed: 11/28/2022] Open
Abstract
Introduction In clinical trials of alemtuzumab, autoimmune thyroid adverse events (AEs) were frequent. Here, we assess the impact of thyroid AEs on health-related quality of life (HRQL) in alemtuzumab-treated patients with relapsing-remitting multiple sclerosis (RRMS). Methods In phase 3 CARE-MS I (NCT00530348) and II (NCT00548405) trials, patients with RRMS were administered alemtuzumab 12 mg/day on 5 consecutive days at baseline and on 3 consecutive days 12 months later. Patients could participate in an extension study (NCT00930553) through year 6. HRQL was assessed at baseline and annually using the Functional Assessment of Multiple Sclerosis (FAMS), EuroQoL-5 Dimension Visual Analog Scale (EQ-5D VAS), and 36-Item Short-Form Survey (SF-36) questionnaires. Outcomes were analyzed in patients with or without thyroid AEs (nonserious or serious). A subset of patients with thyroid AEs was analyzed to assess HRQL before and during the onset of thyroid AEs. Results A total of 811 CARE-MS patients were treated with alemtuzumab. Of these, 342 (42%) patients experienced thyroid AEs over 6 years; serious thyroid AEs occurred in 44 (5%) patients. At year 6, HRQL outcomes generally remained slightly improved or similar to core study baseline in alemtuzumab-treated patients with or without thyroid AEs: FAMS (least-squares mean change from baseline without thyroid AEs, 0.7; with nonserious thyroid AEs, 5.1; with serious thyroid AEs, − 5.3), EQ-5D VAS (2.0; 3.0; − 6.8), SF-36 mental component summary (MCS [0.6; 1.6; − 2.8]), SF-36 physical component summary (PCS [0.8; 1.0; 1.1]). Over 6 years, 63–82% of patients in each group had improved/stable SF-36 MCS and PCS scores. Among patients with thyroid AE onset in year 3 (peak incidence), there were minimal differences between HRQL outcomes before onset (year 2) and after onset (year 3). Conclusion Autoimmune thyroid AEs (serious and nonserious) had minimal impact on HRQL in alemtuzumab-treated patients. These data may aid therapeutic decisions in patients with relapsing MS. Electronic supplementary material The online version of this article (10.1007/s40120-020-00191-7) contains supplementary material, which is available to authorized users. This study looked at alemtuzumab, an approved treatment for multiple sclerosis (MS). People who receive alemtuzumab may develop thyroid problems. The researchers wanted to know whether people who developed thyroid problems with alemtuzumab had a worse quality of life compared with those who did not. The researchers measured quality of life using a questionnaire. The questionnaire looked at people’s physical, social, and psychological well-being over 6 years. A total of 811 people with MS treated with alemtuzumab took part in this study. Of these, 469 people (58%) did not develop thyroid problems and 342 people (42%) developed thyroid problems. The thyroid problems were serious in 44 people. The researchers observed that thyroid problems during alemtuzumab treatment did not make quality of life worse in most people. Some people with serious thyroid problems had worsened quality of life; this was mostly among people who required certain treatments for their thyroid problems. Quality of life did not change much in people while the thyroid problems were ongoing. This study shows that thyroid problems after alemtuzumab treatment for MS have little negative impact on quality of life for most people. These findings may help healthcare providers make decisions about MS treatment.

Abstract
Purpose: To describe drug-use patterns in patients with multiple sclerosis (MS) using disease-modifying drugs (DMDs) and to estimate the incidence of severe adverse events (SAEs) of treatment. Methods: We conducted a cohort study within the German Pharmacoepidemiological Research Database between January 1, 2006 and December 31, 2013. MS patients on DMDs were described in terms of clinical characteristics and drug-use patterns. Next, we assessed the incidence of AEs in new users of fingolimod, natalizumab, glatiramer acetate, and IFNβ1a. Results: Among approximately 11 million insured members of German Statutory Health Insurance, the DMD-user cohort comprised 15,377 patients with MS, with a mean age of 39.6 years and 68% females. Nearly half of all DMD users had a diagnosis of depression, with prevalence ranging from 40.1% for IFNβ1a to 62.3% for immunoglobulins. The overall rate of MS relapses per patient and year was 0.34 (95% CI 0.33-0.34). During an average follow-up of 1,650 days, the majority (42.4%) of MS patients were adherent to DMD treatment ("continuous single users"), followed by patients interrupting treatment (39.5%, "interrupters"). Switch of DMD treatment (11.9%) was less frequent, and only 5.6% discontinued treatment. Treatment discontinuation was most common in users of natalizumab (7.5%) and IFNβ1b (7.0%). The most frequent SAE was hospitalization for depression, followed by any infectious disease and any malignancy. The incidence rate of all adverse events did not significantly differ across different DMDs. Conclusion: Treatment discontinuation with DMDs and treatment switch were rare. Causes of rather frequent DMD-treatment interruption have to be evaluated in further studies based on primary data collection. Active safety monitoring of new DMDs based on claims data requires large data sets to detect rare AEs and availability of up-to-date data.

Abstract
INTRODUCTION Multiple sclerosis (MS) treatment has changed considerably in recent years thanks to the introduction of ever-more-powerful drugs. Unfortunately, the higher efficacies of these therapies are associated with increased risks of severe adverse events. In this scenario, neurologists and persons with MS (pwMSs) must now balance benefits and risks when making decisions regarding MS management. Areas covered: This review highlights the importance of the risk perception of pwMSs and their neurologists in the shared decision-making process in MS management, taking into account different ways improve the empowerment and engagement of pwMSs. Expert commentary: The shared decision-making process in MS is strongly influenced by an individual's risk perception, which is dynamic and influenced by the personal, emotional, social, and experiential factors of both the pwMSs and neurologists.

Abstract
Background: While many studies have previously focused on fingolimod's effect on immune cells, the effect it has on circulating and local central nervous system platelets (Plts) has not yet been investigated. This study will elucidate what effects fingolimod treatment has on multiple sclerosis (MS) patients’ plasma Plt levels. In addition, it will propose possible reasoning for these effects and suggest further investigation into this topic. Methods: This quasi-experimental study used patients from the Isfahan Multiple Sclerosis Society to produce a subject pool of 80 patients, including 14 patients who ceased fingolimod use due to complications. The patients had their blood analyzed to determine Plt levels both 1-month prior to fingolimod treatment and 1-month after fingolimod treatment had been started. Results: The mean level of Plts before initiation of fingolimod therapy (Plt1) among these MS patients was 256.53 ± 66.26. After 1-month of fingolimod treatment, the Plt level yielded an average of 229.96 ± 49.67 (Plt2). This number is significantly lower than the average Plt count before treatment (P < 0.01). Conclusions: MS patients taking oral fingolimod treatment may be at risk for side-effects caused by low Plt levels. This may not be a factor for patients with higher or normal Plt levels. However, a patient with naturally low Plt levels may experience a drop below the normal level and be at risk for excessive bleeding. In addition to these possible harmful side-effects, the decreased Plt population may pose positive effects for MS patients.

Abstract
Mitoxantrone is an immunosuppressive drug approved for aggressive relapsing and progressive multiple sclerosis. In recent years, its use has decreased due to the risk of severe adverse events and the introduction of novel therapies, such as natalizumab or fingolimod. Mitoxantrone is effective in reducing inflammatory activity by decreasing the number of relapses and MRI lesions and simultaneously decreasing the worsening of disability. Apart from its role as a second/third-line therapy, some studies suggest its use as an induction therapy. However, mitoxantrone use is limited because of its potential risk of severe adverse events, such as cardiotoxicity and the induction of therapy-related acute leukemia. Genetic markers are on evaluation to predict side effects and therapeutic efficacy, which is consistent with the direction of personalized treatment. Considering its efficacy and the potential risks, mitoxantrone use is limited to active patients after a careful, individualized evaluation of the risk/benefit balance.

Abstract
Clinical trials have generated a wealth of data on the safety profile of interferon β-1b for patients with multiple sclerosis (MS). In general, interferon β-1b has not been associated with serious or life-threatening side effects during long-term treatment. Flu-like symptoms, injection site reactions, depression, and elevated liver transaminases were the most common adverse events in clinical trials. This review will discuss the rates of these and other common adverse events observed in 3 clinical trials of interferon β-1b: BENEFIT, BEYOND, and the 16-year Long-Term Follow-up (LTF) of the pivotal interferon β-1b trial in MS, as well as how these adverse events may influence patient and physician decision making when selecting a disease-modifying therapy. In addition, we will discuss the effects of interferon β-1b on mortality in the 16-year and 21-year LTF studies.
