Real-world therapy management of patients with multiple sclerosis receiving cladribine tablets beyond year 4 - Results from a German cladribine cohort.

BACKGROUND: The current approval of oral cladribine covers four years, with two treatment courses in the first two years, followed by two treatment-free years. For decision-making in year 5, experts recommend three scenarios: Extending the treatment-free period, retreatment with cladribine, or therapy switch. OBJECTIVE: To assess the implementation of the three year-5-scenarios in clinical practice in a large multicentric real-world cohort in Germany. METHODS: Data from adult patients diagnosed with highly active RMS (first dose between 8/2017 and 8/2018) were included. The primary outcome was the percentages of patients who remained treatment-free in year 5, were retreated with cladribine, or switched to another therapy. RESULTS: In total, 187 patients (75 % female, mean age 38.6 years, median EDSS 2.5, 21 % DMT-naive) were evaluated. Overall, 27 (14 %) switched treatment within year 1-4, 36 (19 %) continued therapy with cladribine tablets in year 5, and 8 (4 %) switched therapy in year 5. All other patients (n = 118, 63 %) continued to be monitored without therapy in year 5. CONCLUSION: The recommended three treatment scenarios in year 5 appear to be feasible in clinical practice. Treatment-free structured monitoring is the most frequently applied strategy, highly likely due to the prospect of continuing low disease activity under cladribine treatment.

Evaluation of Patient-Reported Outcomes in Patients with Relapsing Multiple Sclerosis Treated with Cladribine Tablets in the CLAWIR Study: 12-Month Interim Analysis.

INTRODUCTION: Patient-reported outcomes (PROs) provide an insightful method of assessing the subjective impact of therapies for those affected by multiple sclerosis (MS), a chronic neurologic disease notable for symptoms of fatigue and reduced physical function. The ongoing CLAWIR study aims to assess the effect of cladribine tablets (3.5 mg/kg cumulative dose over 2 years) in patients with highly active relapsing MS focusing on PROs of fatigue, physical function, treatment satisfaction, and work productivity. Here, we report on a pre-planned analysis at 12 months after treatment initiation with cladribine tablets. METHODS: CLAWIR is a 2-year, multicenter, prospective, observational study of patients with relapsing MS newly initiating cladribine tablets. The following PROs were analyzed: PRO Measurement Information System (PROMIS®) Fatigue MS (v1.0) and Physical Function MS (v2.1), Treatment Satisfaction Questionnaire for Medication (TSQM, v1.4), and Work Productivity and Activity Impairment MS Questionnaire (WPAI-MS). Data were analyzed descriptively. RESULTS: In total, 128 patients were eligible for analysis: 95 females (74.2%); median (range) age 34.5 (29, 44) years; 34 patients (26.6%) were treatment-naïve, and 89 (69.5%) were early switchers from platform therapies (the remaining 5 patients [3.9%] switched from a high-efficacy disease-modifying therapy). PROMIS® Fatigue MS mean (± standard deviation [SD]) T-scores decreased from 54.6 (± 9.59) at baseline to 51.8 (± 10.30) at 12 months, indicating an alleviation of fatigue, whereas PROMIS® Physical Function MS mean T-scores remained stable over time [baseline: 49.4 (± 10.69); 12 months: 50.3 (± 10.88)]. TSQM v1.4 mean scores indicated an improvement over time, increasing from 52.2 (± 27.79) at baseline to 81.4 (± 17.06) at 12 months for global satisfaction. WPAI-MS scores also showed an improvement across all four domains over 12 months. CONCLUSION: This real-world study demonstrates the effect of cladribine tablets over 12 months on PROs of fatigue, physical function, treatment satisfaction, and work productivity. TRIAL REGISTRATION: The CLAWIR study is registered at the German Federal Institute for Drugs and Medical Devices with the internal NIS number 7469.

Assessment of the treating physicians' first-hand experience with handling and satisfaction of ofatumumab therapy: findings from the PERITIA survey conducted in Europe.

BACKGROUND: Real-world evidence on experience and satisfaction of ofatumumab as a treatment option for relapsing multiple sclerosis (RMS) is limited. OBJECTIVE: To present cumulative responses from a questionnaire related to first-hand experience of treating physicians on handling and convenience of ofatumumab therapy along with concerns related to COVID-19. METHODS: PERITIA was a multicentre survey conducted to collect responses from the ASCLEPIOS I/II trial investigators from Europe via an online questionnaire. RESULTS: Forty-six physicians (Germany, n = 14; Spain, n = 12; Portugal, n = 10; Italy, n = 10) completed the survey. Overall, 43% of the physicians considered the benefit-risk ratio of ofatumumab as very good. Over 93% were in favour of ofatumumab self-administration at home and the majority (83%) believed it to be completely true that self-administration of ofatumumab eases the burden for patients in terms of time. All investigators would like to potentially use anti-CD20 therapy as a long-term strategy. Even during the COVID-19 pandemic, physicians were in favour of a self-administration of MS therapy at home over other anti-CD20 therapy infusions. CONCLUSION: European neurologists who were part of this survey considered the benefit-risk-ratio of ofatumumab as favourable and the monthly self-administered subcutaneous injections offering convenience for patients in the clinical practice.

An ID-Associated Application to Facilitate Patient-Tailored Management of Multiple Sclerosis.

Despite improvements in diagnosis and treatment, multiple sclerosis (MS) is the leading neurological cause of disability in young adults. As a chronic disease, MS requires complex and challenging management. In this context, eHealth has gained an increasing relevance. Here, we aim to summarize beneficial features of a mobile app recently implemented in clinical MS routine as well as beyond MS. PatientConcept is a CE-certified, ID-associated multilingual software application allowing patients to record relevant health data without disclosing any identifying data. Patients can voluntarily share their health data with selected physicians. Since its implementation in 2018, about 3000 MS patients have used PatientConcept. Initially developed as a physician-patient communication platform, the app maps risk management plans of all current disease modifying therapies and thereby facilitates adherence to specified monitoring appointments. It also allows continuous monitoring of various PROs (Patient Reported Outcomes), enabling a broad overview of the disease course. In addition, various studies/projects currently assess monitoring, follow-up, diagnostics and telemetric evaluations of patients with other diseases beyond MS. Altogether, PatientConcept offers a broad range of possibilities to support physician-patient communication, implementation of risk management plans and assessment of PROs. It is a promising tool to facilitate patient-tailored management of MS and other chronic diseases.

Oral pulsed therapy of relapsing multiple sclerosis with cladribine tablets - expert opinion on issues in clinical practice.

BACKGROUND: Oral cladribine is the first oral pulsed therapy licensed for relapsing multiple sclerosis (RMS). Three years after the introduction into the European market, we evaluated practical aspects in the use of cladribine tablets, incorporating the experience gained in routine clinical practice and real-world studies. METHODS: Based on a structured review process, a panel of nine neurologists experienced in MS therapy discussed salient statements regarding the use of cladribine tables. For each statement the level of evidence was determined according to the levels of evidence recommended by the Centre for Evidence-Based Medicine, Oxford. The strength of each expert statement was then evaluated by means of a linear scale from 1 (very strong rejection) to 9 (very strong approval). Votes were collected by a formalized blinded process. Consent was considered to be reached if at least 75% of the experts agreed on a particular statement (i.e. voted for 7-9 points on the linear scale). RESULTS: . Statements include efficacy in early RMS, risk of side effects and infections, vaccination, pregnancy, and monitoring requirements. CONCLUSION: The consented recommendations summarize the practical experience inthe use of cladribine tablets in a real-world setting. These may provide guidance for unanswered questions arising with the introduction of new treatments such as cladribine tablets.

Mental symptoms in MS (MeSyMS): Development and validation of a new assessment.

BACKGROUND: Patients with Multiple Sclerosis (MS) have an increased risk of suffering from mental and neuropsychiatric symptoms. So far, a fundamental problem in the clinical care of MS patients is that these symptoms are underdiagnosed and, as a consequence, often remain untreated. Present assessment tools have not been developed to be applied in patients with MS. This study aims to develop and validate a new questionnaire to identify disease-related mental symptoms in MS patients. METHODS: A questionnaire has been developed by including the following subscales: social and emotional health problems, anxiety, and depression. To evaluate test quality and internal consistency, an item analysis has been conducted. After matching MS patients and control subjects on age and gender, we conducted group comparisons, a Receiver Operating Characteristic (ROC) Curve analysis and a binary logistic regression model. RESULTS: In total, 314 MS patients and 100 matched control subjects were analysed. After performed item analysis, the questionnaire revealed an excellent internal consistency (α=0.94). Compared to control subjects, MS patients showed significant mental health problems in all three dimensions. In comparison to the subscales, the dimension of social and emotional health problems revealed the highest accuracy (AUC = 0.75; d = 0.948) and turned out to be the only scale that reliably differentiated between the groups. CONCLUSIONS: MeSyMS constitutes a valid screening instrument to detect mental symptoms in MS. Social and emotional health problems turned out to be the most important aspect when identifying disease-related mental health symptoms in MS.

Listeria Meningitis Complicating Alemtuzumab Treatment in Multiple Sclerosis--Report of Two Cases.

Alemtuzumab, a humanized monoclonal antibody targeting the surface molecule CD52, leads to a rapid depletion of immune cells in the innate and adaptive immune system. In phase 2 and 3 trials in multiple sclerosis (MS), infections have been reported more frequently in alemtuzumab than in interferon beta treated patients. Here we report two patients treated with alemtuzumab for MS developing Listeria meningitis few days after the first infusion cycle. Both patients recovered completely after prompt diagnosis and adequate treatment. Physicians and patients should be aware of this serious, but treatable complication.

Candidate biomarkers of chronic inflammatory demyelinating polyneuropathy (CIDP): proteome analysis of cerebrospinal fluid.

We aimed to identify disease-related biomarkers in CIDP. Using the two-dimensional difference in gel electrophoresis (2-D-DIGE), we compared CSF from patients with CIDP (n = 11) and controls (n = 11). Protein spots that showed a significant difference were further analyzed by MALDI-TOF mass spectrometry. We identified 10 proteins that were upregulated in CIDP (two transferrin isoforms, alpha-1 acid glycoprotein 1 precursor, apolipoprotein A IV, two haptoglobin isoforms, transthyretin (TTR), retinol binding protein and two isoforms of proapolipoprotein) and 1 protein that was downregulated (integrin beta 8). The pathophysiological role of these proteins remains to be clarified by further studies.
