Evaluation of risk management in a natalizumab home infusion procedure.

Natalizumab is a well-established disease-modifying therapy used in active multiple sclerosis (MS). The most serious adverse event is progressive multifocal leukoencephalopathy. For safety reasons, hospital implementation is mandatory. The SARS-CoV-2 pandemic has deeply affected hospital practices leading French authorities to temporarily authorize to administer the treatment at home. The safety of natalizumab home administration should be assessed to allow ongoing home infusion. The aim of the study is to describe the procedure and assess the safety in a home infusion natalizumab model. Patients presenting relapsing-remitting MS treated by natalizumab for over two years, non-exposed to John Cunningham Virus (JCV) and living in the Lille area (France) were included from July 2020 to February 2021 to receive natalizumab infusion at home every four weeks for 12 months. Teleconsultation occurrence, infusion occurrence, infusion cancelling, JCV risk management, annual MRI completion were analyzed. The number of teleconsultations allowing infusion was 365 (37 patients included in the analysis), all home infusions were preceded by a teleconsultation. Nine patients did not complete the one-year home infusion follow-up. Two teleconsultations canceled infusions. Two teleconsultations led to a hospital visit to assess a potential relapse. No severe adverse event was reported. All 28 patients who have completed the follow-up benefited from biannual hospital examination and JCV serologies and annual MRI. Our results suggested that the established home natalizumab procedure was safe using the university hospital home-care department. However, the procedure should be evaluated using home-based services outside the university hospital.

[Therapeutic Strategies and Disease-Modifying Therapies for Multiple Sclerosis].

Multiple sclerosis is an inflammatory demyelinating disease of unknown cause that affects the central nervous system. Although it was once deemed "incurable," many disease-modifying therapies have been introduced since the beginning of the 20th century; eight of these are now available in Japan. Treatment for multiple sclerosis is undergoing a significant shift from the safety-oriented "escalation strategy," in which the patient is initially administered medications with low risks of side effects but moderate efficacy, to a "personalized approach" based on individual prognostic factors followed by an "early top-down strategy" in which higher efficacy treatments are initiated first. Disease-modifying drugs for multiple sclerosis can be high- (fingolimod, ofatumumab, natalizumab) or moderate-efficacy (interferon beta, glatiramer acetate, dimethyl fumarate), and there are also disease-modifying therapies for secondary progressive multiple sclerosis (siponimod and ofatumumab). Approximately 20,000 Japanese patients have multiple sclerosis, and this number continues to increase. Many neurologists are expected to prescribe high-efficacy drugs in the future. The risk management of adverse events, particularly progressive multifocal leukoencephalopathy, is required to ensure that the importance of safety never be underestimated, even though treatment efficacy is the main focus.

Assessment of immunological anti-platelet factor 4 antibodies for vaccine-induced thrombotic thrombocytopenia (VITT) in a large Australian cohort: A multicenter study comprising 1284 patients.

BACKGROUND: Vaccine-induced thrombotic thrombocytopenia (VITT) is a rare complication of adenovirus-based vaccines aimed to prevent and minimize COVID-19 and related pathophysiology. OBJECTIVES: To describe patterns of testing for anti-platelet factor 4 (PF4) antibodies using various ELISA assays in a large Australian cohort and comparative functional platelet activation assays in a subset. PATIENTS/METHODS: Asserachrom HPIA IgG ELISA was performed in 1284 patients over a period of 12 months, supplemented in select cohorts by comparative ELISA using three other methods (n = 78-179), three different functional assays (flow cytometry, serotonin release assay, and/or Multiplate; n = 476), and rapid immunological chemiluminescence anti-PF4 assay (n = 460), in a multicenter study. RESULTS: For first episode presentations, 190/1284 (14.8%) ELISA tests were positive. Conversely, most (445/460; 96.7%) chemiluminescence anti-PF4 test results were negative. All functional assays showed associations of higher median ELISA optical density with functional positivity and with high rates of ELISA positivity (64.0% to 85.2%). Data also identified functional positivity in 14.8%-36.0% of ELISA negative samples, suggesting false negative VITT by HPIA IgG ELISA in upward of one third of assessable cases. CONCLUSION: To our knowledge, this is the largest multicenter evaluation of anti-PF4 testing for investigation of VITT. Discrepancies in test results (ELISA vs. ELISA or ELISA vs. functional assay) in some patients highlighted limitations in relying on single methods (ELISA and functional) for PF4 antibody detection in VITT, and also highlights the variability in phenotypic test presentation and pathomechanism of VITT.

Patient and Caregiver Experiences With and Perceptions of Risk Evaluation and Mitigation Strategy Programs With Elements to Assure Safe Use.

Importance: The US Food and Drug Administration (FDA) Amendments Act of 2007 authorized the FDA to impose safety requirements on drugs with important risks, such as prescriber certification or routine laboratory testing, to ensure that the benefits of use outweighed the risks. However, little is known about patient and caregiver experiences with these Risk Evaluation and Mitigation Strategy (REMS) programs with Elements to Assure Safe Use (ETASU). Objective: To understand patient and caregiver experiences with and perceptions of REMS programs with ETASU. Design, Setting, and Participants: This qualitative study included semistructured qualitative phone interviews conducted between 2016 and 2017, with initial analysis performed in 2017 and reanalysis performed in 2021. Adult patients prescribed natalizumab or sodium oxybate, adult patients or caregivers of adult patients prescribed vigabatrin, and adult female patients of reproductive age prescribed riociguat were included. Main Outcomes and Measures: Assessment of knowledge, decision-making, medication access, and perceptions of medical privacy. Results: Among 63 participants, 46 (73%) were female. Twenty-five participants (40%) had taken natalizumab, 10 (16%) riociguat, 15 (24%) sodium oxybate, and 10 (16%) vigabatrin. One participant had taken both natalizumab and vigabatrin; 4 (6%) were caregivers of patients using vigabatrin. Most participants expressed knowledge of REMS program requirements, but many lacked the insight that these requirements were part of an FDA-mandated special safety program and expressed difficulty understanding program education materials. REMS requirements made some participants more likely to initiate treatment. However, many reported burdens accessing medication, including the need to travel to certified prescribers or pharmacies. Manufacturer access to personal health information was also controversial, although some participants expressed an altruistic desire to assist others. Conclusions and Relevance: This qualitative study found that REMS programs with ETASU reassured patients and their caregivers about drug safety and helped support medication initiation. However, steps are needed to improve the quality of REMS educational materials, promote efficient medication access, and protect patient privacy.

A safety review of biologic therapies for the management of hidradenitis suppurativa and unmet needs.

INTRODUCTION: Hidradenitis suppurativa (HS) is a chronic, debilitating inflammatory skin disorder characterized by nodules, abscesses, fistulae, and significant scarring in intertriginous areas rich in apocrine glands. Immunomodulator drugs, including biologics, are a mainstay of treatment for this disease. AREAS COVERED: This review details the safety profiles of various biologic therapies currently available commercially that have been tried for HS as assessed in clinical trials and observational studies. As the only Food and Drug Administration (FDA)-approved medication for the treatment of moderate-to-severe HS, adalimumab is discussed in the most detail. Additional biologic medications, including tumor necrosis factor α (TNFα) inhibitors, interleukin 1 (IL-1) inhibitors, IL-12 and IL-23 inhibitors, IL-17 inhibitors, and IL-23 inhibitors, are discussed as well. Safety concerns in special populations, including pregnant women and children, are outlined. EXPERT OPINION: Existing data support excellent short-term and long-term safety profiles for adalimumab, although caution must be taken with use in high-risk patient populations, including those with chronic infections or increased risk of malignancy. Based on their safety data for other indications, additional biologic agents appear safe in HS as well. However, further research is needed to fully understand the safety profiles of these medications in the HS population.

Assessment and Management of Cardiotoxicity in Hematologic Malignancies.

With the increasing overall survival of cancer patients due to recent discoveries in oncology, the incidence of side effects is also rising, and along with secondary malignancies, cardiotoxicity is one of the most concerning side effects, affecting the quality of life of cancer survivors. There are two types of cardiotoxicity associated with chemotherapy; the first one is acute, life-threatening but, fortunately, in most of the cases, reversible; and the second one is with late onset and mostly irreversible. The most studied drugs associated with cardiotoxicity are anthracyclines, but many new agents have demonstrated unexpected cardiotoxic effect, including those currently used in multiple myeloma treatment (proteasome inhibitors and immunomodulatory agents), tyrosine kinase inhibitors used in the treatment of chronic myeloid leukemia and some forms of acute leukemia, and immune checkpoint inhibitors recently introduced in treatment of refractory lymphoma patients. To prevent irreversible myocardial damage, early recognition of cardiac toxicity is mandatory. Traditional methods like echocardiography and magnetic resonance imaging are capable of detecting structural and functional changings, but unable to detect early myocardial damage; therefore, more sensible biomarkers like troponins and natriuretic peptides have to be introduced into the current practice. Baseline assessment of patients allows the identification of those with high risk for cardiotoxicity, while monitoring during and after treatment is important for early detection of cardiotoxicity and prompt intervention.

Systematic Review: Monoclonal Antibody-Induced Subacute Cutaneous Lupus Erythematosus.

BACKGROUND: Subacute cutaneous lupus erythematosus (SCLE) lacks consensus diagnostic criteria and the pathogenesis is poorly understood. There are increasing reports of SCLE induced by monoclonal antibodies (mAbs), but there are limited data on the aetiology, clinical characteristics and natural course of this disease. METHODS: We devised a set of diagnostic criteria for SCLE in collaboration with a multinational, multispecialty panel. This systematic review employed a two-layered search strategy of five databases for cases of mAb-induced SCLE (PROSPERO registered protocol CRD42019116521). To explore the relationship between relative mAb use and the number of SCLE cases reported, the estimated number of mAb users was modelled from 2013 to 2018 global commercial data and estimated annual therapy costs. RESULTS: From 40 papers, we identified 52 cases of mAb-induced SCLE, occurring in a cohort that was 73% female and with a median age of 61 years. Fifty percent of cases were induced by anti-tumour necrosis factor (TNF)-ɑ agents. A median of three drug doses preceded SCLE onset and the lesions lasted a median of 7 weeks after drug cessation. Oral and topical corticosteroids were most frequently used. Of the licensed mAbs, adalimumab, denosumab, rituximab, etanercept and infliximab were calculated to have the highest relative number of yearly users based on global sales data. Comparing the number of mAb-induced SCLE cases with estimated yearly users, the checkpoint inhibitors pembrolizumab and nivolumab showed strikingly high rates of SCLE relative to their global use, but ipilimumab did not. CONCLUSION: We present the first systematic review characterising mAb-induced SCLE with respect to triggers, clinical signs, laboratory findings, prognosis and treatment approaches. We identify elevated rates associated with the use of checkpoint inhibitors and anti-TNFɑ agents.

Comprehensive assessment of side effects in COVID-19 drug pipeline from a network perspective.

Currently, coronavirus disease 2019 (COVID-19), has posed an imminent threat to global public health. Although some current therapeutic agents have showed potential prevention or treatment, a growing number of associated adverse events have occurred on patients with COVID-19 in the course of medical treatment. Therefore, a comprehensive assessment of the safety profile of therapeutic agents against COVID-19 is urgently needed. In this study, we proposed a network-based framework to identify the potential side effects of current COVID-19 drugs in clinical trials. We established the associations between 116 COVID-19 drugs and 30 kinds of human tissues based on network proximity and gene-set enrichment analysis (GSEA) approaches. Additionally, we focused on four types of drug-induced toxicities targeting four tissues, including hepatotoxicity, renal toxicity, lung toxicity, and neurotoxicity, and validated our network-based predictions by preclinical and clinical evidence available. Finally, we further performed pharmacovigilance analysis to validate several drug-tissue toxicities via data mining adverse event reporting data, and we identified several new drug-induced side effects without labeling in Food and Drug Administration (FDA) drug instructions. Overall, this study provides forceful approaches to assess potential side effects on COVID-19 drugs, which will be helpful for their safe use in clinical practice and promoting the discovery of antiviral therapeutics against SARS-CoV-2.

Challenges in the management of patients with systemic light chain (AL) amyloidosis during the COVID-19 pandemic.

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-associated coronavirus disease 2019 (COVID-19) is primarily manifested as a respiratory tract infection, but may affect and cause complications in multiple organ systems (cardiovascular, gastrointestinal, kidneys, haematopoietic and immune systems), while no proven specific therapy exists. The challenges associated with COVID-19 are even greater for patients with light chain (AL) amyloidosis, a rare multisystemic disease affecting the heart, kidneys, liver, gastrointestinal and nervous system. Patients with AL amyloidosis may need to receive chemotherapy, which probably increases infection risk. Management of COVID-19 may be particularly challenging in patients with AL amyloidosis, who often present with cardiac dysfunction, nephrotic syndrome, neuropathy, low blood pressure and gastrointestinal symptoms. In addition, patients with AL amyloidosis may be more susceptible to toxicities of drugs used to manage COVID-19. Access to health care may be difficult or limited, diagnosis of AL amyloidosis may be delayed with detrimental consequences and treatment administration may need modification. Both patients and treating physicians need to adapt in a new reality.

Disease-Modifying Therapy Adherence and Associated Factors in a National Sample of Medicare Patients With Multiple Sclerosis.

OBJECTIVES: Disease-modifying therapies (DMTs) reduce relapse rates and disability progression for relapsing multiple sclerosis (MS). Although 25% to 30% of all US patients with MS are Medicare beneficiaries, limited information exists on this population. This is the first study using national Medicare data to (1) describe characteristics of patients with MS using DMTs, (2) estimate adherence to DMTs over a 1-year and 3-year follow-up, and (3) examine factors associated with DMT adherence. METHODS: This retrospective claims analysis used 2011-2014 100% Medicare files. Monthly adherence to MS DMTs was defined as the proportion of days covered ≥0.80 with any DMT in each month for 1-year (n = 36 593) and 3-year (n = 17 599) follow-up samples of MS DMT users. Generalized estimating equation logistic regressions were used to estimate factors associated with adherence to DMTs. RESULTS: Over 90% of patients were eligible for Medicare owing to disability, and about three-quarters qualified for low-income subsidies. A downward trend in DMT adherence was observed over time in both samples. Monthly adherence dropped significantly between December of the prior year to January of the following year (from 76% to 65% in the 1-year follow-up sample and similar drops seen across all years in the 3-year follow-up sample). Multivariable regressions indicated characteristics such as being low-income, having a disability, and having high patient out-of-pocket DMT costs associated with poor adherence to DMTs. CONCLUSION: Our study provides important insights into the characteristics and DMT adherence of Medicare patients with MS and highlights the need for interventions and policies mitigating barriers to adherence in this population.

Prevalence of cervical HPV and attitude towards cervical screening in IBD patients under immunomodulatory treatment: a multidisciplinary management experience.

OBJECTIVE: Therapeutic strategies for Inflammatory Bowel Diseases (IBD: Crohn's disease and Ulcerative Colitis) have improved but the risk for HPV infection in patients under immunomodulatory/biologic treatment is unclear. Objective of the study is to identify the attitude of patients and caregivers to cervical screening. To determine the prevalence of HPV and cervical lesions in IBD patients receiving immunomodulatory/biological treatment. PATIENTS AND METHODS: IBD patients treated with immunomodulators were enrolled from November 2016 to September 2017, thanks to a multidisciplinary cooperation. A survey was administered to enrolled patients as well as to a selected network of IBD expert physicians. Patients who consented underwent gynecological examination, smear, HPV DNA test, colposcopy, vaginal and cervical microbiological swabs. RESULTS: 294 patients from AMICI Onlus Association, 119 patients from the hospital clinic, 30 doctors from national IBD centers participated to the survey. 19 patients from the IBD clinic underwent cervical screening. More than 90% of doctors consider their patients at risk of cervical cancer. A low prevalence of high-risk genotypes and related HPV lesions and an increased prevalence of bacterial vaginosis emerged in the studied population. CONCLUSIONS: Biological drugs could lead to a positive immunomodulation towards HPV infection. In IBD patients an alteration of the vaginal and intestinal microbiota seems to be coexisting.

Immune thrombocytopenia in alemtuzumab-treated MS patients: Incidence, detection, and management.

BACKGROUND: Alemtuzumab is a highly effective therapy for relapsing-remitting multiple sclerosis (RRMS), and immune thrombocytopenia (ITP) has been identified as a risk. OBJECTIVE: To examine ITP incidence, treatment, and outcomes during the clinical development of alemtuzumab for RRMS and discuss postmarketing experience outside clinical trials. METHODS: CAMMS223 and Comparison of Alemtuzumab and Rebif® Efficacy in Multiple Sclerosis (CARE-MS) I and II investigated two annual courses of alemtuzumab 12 mg (or 24 mg in CAMMS223/CARE-MS II) versus subcutaneous interferon beta-1a three times per week. Patients completing core studies could enroll in an extension. Monthly monitoring for ITP continued until 48 months after the last alemtuzumab infusion. RESULTS: Of 1485 alemtuzumab-treated MS patients in the clinical development program, 33 (2.2%) developed ITP (alemtuzumab 12 mg, 24 [2.0%]; alemtuzumab 24 mg, 9 [3.3%]) over median 6.1 years of follow-up after the first infusion; most had a sustained response to first-line ITP therapy with corticosteroids, platelets, and/or intravenous immunoglobulin. All cases occurred within 48 months of the last alemtuzumab infusion. Postmarketing surveillance data suggest that the ITP incidence is not higher in clinical practice than in clinical trials. CONCLUSION: Alemtuzumab-associated ITP occurs in approximately 2% of patients and is responsive to therapy. Careful monitoring is key for detection and favorable outcomes.

Derivation and Validation of a Risk Assessment Model for Immunomodulatory Drug-Associated Thrombosis Among Patients With Multiple Myeloma.

BACKGROUND: Although venous thromboembolism (VTE) is a significant complication for patients with multiple myeloma (MM) receiving immunomodulatory drugs (IMiDs), no validated clinical model predicts VTE in this population. This study aimed to derive and validate a new risk assessment model (RAM) for IMiD-associated VTE. METHODS: Patients with newly diagnosed MM receiving IMiDs were selected from the SEER-Medicare database (n=2,397) to derive a RAM and then data from the Veterans Health Administration database (n=1,251) were used to externally validate the model. A multivariable cause-specific Cox regression model was used for model development. RESULTS: The final RAM, named the "SAVED" score, included 5 clinical variables: prior surgery, Asian race, VTE history, age ≥80 years, and dexamethasone dose. The model stratified approximately 30% of patients in both the derivation and the validation cohorts as high-risk. Hazard ratios (HRs) were 1.85 (P<.01) and 1.98 (P<.01) for high- versus low-risk groups in the derivation and validation cohorts, respectively. In contrast, the method of stratification recommended in the current NCCN Guidelines for Cancer-Associated Venous Thromboembolic Disease had HRs of 1.21 (P=.17) and 1.41 (P=.07) for the corresponding risk groups in the 2 datasets. CONCLUSIONS: The SAVED score outperformed the current NCCN Guidelines in risk-stratification of patients with MM receiving IMiD therapy. This clinical model can help inform providers and patients of VTE risk before IMiD initiation and provides a simplified clinical backbone for further prognostic biomarker development in this population.

Patients' preferences and willingness-to-pay for disease-modifying therapies.

BACKGROUND: While disease-modifying therapies (DMTs) for multiple sclerosis (MS) treatments are costly, patient valuation of DMTs has not been examined. The objective of this study was to examine patients' preferences and willingness-to-pay (WTP) for DMTs. METHODS: Six attributes (i.e., number of relapses, percentage of disability progression, percentage of severe adverse events, route of administration, frequency of administration, and out-of-pocket cost) and their levels were used to develop a discrete choice experiment questionnaire. Each questionnaire comprised seven choice sets and each choice set contained two hypothetical DMTs and an opt-out alternative. A total of 1,200 U.S. patients with MS were asked to choose a DMT option or opt-out in each choice set. Multinomial logit model was used to determine relative preferences of each attribute. WTPs for all attributes and DMTs were calculated. RESULTS: A total of 508 patients were analyzed. Patients preferred DMTs with lower relapse rate, lower disability progression, lower severe adverse event, lower frequency of administration, and lower cost. In addition, they preferred oral DMTs. They were willing to pay $2,768, $289, $292, and $76 a month in exchange for every 1-time decrease in the number of relapses in two years, every 1% decrease in disability progression in two years, every 1% decrease in severe adverse events, and every 1-time decrease in the frequency of administration per month, respectively. The patients were willing to pay, in relation to market prices, between $7,020 and $134,934 per year for all DMTs, but interferon beta-1a SC. CONCLUSIONS: Patients with MS considered relapse rate, disability progression, severe adverse events, route of administration, frequency of administration, and out-of-pocket cost, when they chose DMTs. Their WTPs for DMTs varied widely.

Safety outcomes of disease-modifying therapies for relapsing-remitting multiple sclerosis: A network meta-analysis.

BACKGROUND: Randomised clinical trials (RCTs) and observational studies have reported adverse events that preclude the use of disease-modifying therapies (DMTs) in relapsing-remitting multiple sclerosis (RRMS) in the long term or in specific populations, however, little is known about the relationship between the use of DMTs and frequency of undesirable events. We aimed to conduct a systematic review and network meta-analyses (NMAs) of RCTs and observational studies to synthesise the evidence on the safety of all available DMTs for patients with RRMS. METHODS: PubMed, Scopus and a manual search were performed. Bayesian NMAs of safety outcomes reported in RCTs and observational studies assessing DMTs as monotherapies were conducted. RESULTS: Forty-seven studies were included in the systematic review. Considering all studies, 368 and 149 different safety outcomes were reported for at least one study and two studies, respectively. Considering clinical trials, 22 NMAs were conducted for 16 outcomes. Regarding geometry metrics, the median number of studies, DMTs, common comparator, strong edge, and patients were 5 (IQR 5-9), 5 (IQR 4-8), 44%, 33%, and 3998 (IQR 3380-6761). In summary, most comparisons showed similar risk of safety events for DMTs and placebo for all outcomes. Considering cohort studies, only three meta-analyses were conducted. CONCLUSION: Safety outcomes are poorly reported in primary studies of DMTs in RRMS, precluding the conduction of robust meta-analyses. Therefore, the current available data on safety of these drugs is not contributing to regulatory and clinical decision making, with adverse event reports underbalanced compared to efficacy outcomes.

Adverse effects of immune-checkpoint inhibitors: epidemiology, management and surveillance.

Immune-checkpoint inhibitors (ICIs), including anti-cytotoxic T lymphocyte antigen 4 (CTLA-4), anti-programmed cell death 1 (PD-1) and anti-programmed cell death 1 ligand 1 (PD-L1) antibodies, are arguably the most important development in cancer therapy over the past decade. The indications for these agents continue to expand across malignancies and disease settings, thus reshaping many of the previous standard-of-care approaches and bringing new hope to patients. One of the costs of these advances is the emergence of a new spectrum of immune-related adverse events (irAEs), which are often distinctly different from the classical chemotherapy-related toxicities. Owing to the growing use of ICIs in oncology, clinicians will increasingly be confronted with common but also rare irAEs; hence, awareness needs to be raised regarding the clinical presentation, diagnosis and management of these toxicities. In this Review, we provide an overview of the various types of irAEs that have emerged to date. We discuss the epidemiology of these events and their kinetics, risk factors, subtypes and pathophysiology, as well as new insights regarding screening and surveillance strategies. We also highlight the most important aspects of the management of irAEs.

Review of the novelties presented at the 2018 ECTRIMS Congress: 11th Post-ECTRIMS Meeting (II). / Revision de las novedades presentadas en el Congreso ECTRIMS 2018: XI Reunion Post-ECTRIMS (II).

The Post-ECTRIMS Meeting was held for the eleventh consecutive year in October 2018 in Madrid, with the aim of analysing the advances made in multiple sclerosis that were highlighted at the latest ECTRIMS annual congress. Based on the issues discussed at this meeting, attended by the nation's foremost opinion leaders on multiple sclerosis, two review articles are presented. This second part includes the growing body of evidence confirming the safety of exposure to disease-modifying treatments in women planning a pregnancy, and the beneficial effect of breastfeeding, provided that the disease is not very active. It addresses data showing how the application of the 2017 McDonald criteria in the paediatric population has significantly improved diagnosis compared to the previous criteria. With regard to progressive multiple sclerosis, the results of neuroprotective drugs are inconclusive, but biomarkers are proposed to improve the evaluation of the therapeutic response. Studies on myelin repair treatments suggest that remyelination in multiple sclerosis is possible. Likewise, there are favourable indications for haematopoietic stem cell transplantation, provided that patients are selected appropriately. On the other hand, we also conduct a review of the similarities and differences of the recommendations in the new clinical practice guidelines. Finally, the positive results of cognitive and motor rehabilitation with the use of new technologies point to the systematic incorporation of these tools in the treatment of the disease in the near future.

TITLE: Revision de las novedades presentadas en el Congreso ECTRIMS 2018: XI Reunion Post-ECTRIMS (II).La reunion Post-ECTRIMS se celebro por undecimo año consecutivo el pasado octubre de 2018 en Madrid, con el objetivo de analizar los avances en esclerosis multiple destacados en el ultimo congreso anual ECTRIMS. Fruto de esta reunion, formada por los lideres de opinion en esclerosis multiple de ambito nacional, se presentan dos articulos de revision. En esta segunda parte, se incluye el creciente numero de evidencias que confirman la seguridad de la exposicion a los tratamientos modificadores de la enfermedad en mujeres que planifican un embarazo, y el efecto beneficioso de la lactancia, siempre y cuando la enfermedad no este muy activa. Se abordan los datos que muestran como la aplicacion de los criterios de McDonald de 2017 en poblacion pediatrica ha mejorado considerablemente el diagnostico en comparacion con los criterios anteriores. En cuanto a la esclerosis multiple progresiva, los resultados de los farmacos neuroprotectores son poco concluyentes, pero se proponen biomarcadores para mejorar la evaluacion de la respuesta terapeutica. Los estudios sobre tratamientos de reparacion de la mielina sugieren que la remielinizacion en la esclerosis multiple es posible. De igual manera, se exponen indicios favorables sobre el trasplante de celulas madre hematopoyeticas, siempre que se seleccione adecuadamente a los pacientes. Por otro lado, se revisan las similitudes y diferencias de las recomendaciones de las nuevas guias de practica clinica publicadas. Por ultimo, los resultados positivos de la rehabilitacion cognitiva y motora con el uso de las nuevas tecnologias vaticinan la incorporacion sistematica de estas herramientas en el tratamiento de la enfermedad en un futuro proximo.

Real-world study of efficacy, risk management and reasons for discontinuation of natalizumab for treatment of multiple sclerosis in Russia.

BACKGROUND: NTZ is approved in Russia for the treatment of highly active relapsing remitting multiple sclerosis and is reimbursed via federal budget program. However, no data about NTZ treatment in Russia and the effect of federal reimbursement have been performed so far. OBJECTIVE: To characterize the population of patients receiving natalizumab and assess the efficacy and risk-management plan (RMP) implementation of NTZ therapy in routine clinical practice in Russia. METHODS: We analyzed data for 334 patients, who received at least one infusion of NTZ. Relapse rate, MRI activity, NEDA-3 status after 2 years were assessed. Anti-JC virus antibodies status and RMP implementation were evaluated. Drop-out rate and reasons for therapy discontinuation were analyzed. RESULTS: Patients switched to natalizumab in Russia are mainly female (63%), with median EDSS score of 3.5 and high disease activity: 93% had at least 1 relapse and 58% had both T1Gd+ and new T2 lesion a year before therapy initiation. Introduction of federal reimbursement allowed patients with less relapses to start therapy with natalizumab. The only predictor of 6-month progression was EDSS score at the baseline of therapy (HR = 2.1375, 95%CI 1.0026-4.5570, p = 0.0492). 82% patients reached NEDA-3 at 24 month of therapy. 25% of patients discontinued NTZ for reasons: tolerability (14.5%), JCV antibody status (61%), and patient's decision (17%). RMP was implemented in only 36% patients. CONCLUSION: Natalizumab appeared to have high efficacy in Russian clinical practice. Federal reimbursement allowed less active patients to start natalizumab. More efforts should be done to improve RMP implementation.

Incidence, management, and outcomes of autoimmune nephropathies following alemtuzumab treatment in patients with multiple sclerosis.

BACKGROUND: Autoimmune disorders including nephropathies have been reported more frequently in alemtuzumab-treated multiple sclerosis (MS) patients than in the general population. OBJECTIVE: Describe instances of autoimmune nephropathy in alemtuzumab-treated MS patients. METHODS: Cases were identified from safety monitoring within the alemtuzumab relapsing-remitting multiple sclerosis (RRMS) clinical development program (CDP) or post-marketing, or following off-label use. RESULTS: As of 16 June 2017, 16 autoimmune nephropathies have occurred following alemtuzumab treatment for MS. The incidence of autoimmune nephropathies was 0.34% within the CDP (5/1485 patients). The five CDP cases (one of anti-glomerular basement membrane (anti-GBM) disease, two of membranous glomerulonephropathy, and two of serum anti-GBM antibody without typical anti-GBM disease) were identified early, responded to conventional therapy (where needed), and had favorable outcomes. Three of 11 cases outside the CDP occurred following off-label alemtuzumab use prior to approval for RRMS and were all anti-GBM disease. Diagnosis was delayed in one of these three cases and another did not receive appropriate treatment; all three cases resulted in end-stage renal failure. All anti-GBM disease cases with documented urinalysis demonstrated prior microscopic hematuria. CONCLUSION: Close monitoring of alemtuzumab-treated MS patients facilitates diagnosis and treatment early in the nephropathy course when preservation of renal function is more likely.

Cardiovascular Complications Associated with Multiple Myeloma Therapies: Incidence, Pathophysiology, and Management.

PURPOSE OF REVIEW: Multiple myeloma is a common hematologic malignancy characterized by recurrent relapsing disease course requiring use of various therapies. Over the past few decades, significant advancements in the treatment of myeloma have occurred including routine use of proteasome inhibitors and immunomodulatory drugs. These have effectively improved survival; however, some also have increased risk of cardiovascular toxicity. Here, we will review the incidence, pathophysiology, and management of cardiovascular complications associated with antimyeloma agents. RECENT FINDINGS: Cardiovascular complications associated with myeloma treatment are common. These cardiovascular complications include accelerated hypertension, ischemic heart disease, congestive heart failure, arrhythmia, pulmonary hypertension, venous thromboembolism, and arterial thromboembolism. Thromboprophylactic strategies during treatment with immunomodulatory agents and screening strategies to detect changes in myocardial function prior to the development of overt heart failure have occurred. Cardiovascular complications associated with proteasome inhibitors and immunomodulatory drugs are an important component in supportive care of patients with myeloma. The incidence of cardiotoxicity is high, and, as such, early intervention and collaborative efforts between cardiologists and oncologists to mitigate and effectively manage these complications are imperative. Additional studies are needed to clarify the underlying pathophysiology and evaluate effective strategies for prevention and treatment.
