  • Sustained Efficacy of Natalizumab in the Treatment of Relapsing-Remitting Multiple Sclerosis Independent of Disease Activity
    Zurich Open Repository and Archive University of Zurich Main Library Strickhofstrasse 39 CH-8057 Zurich www.zora.uzh.ch Year: 2012 Sustained efficacy of natalizumab in the treatment of relapsing-remitting multiple sclerosis independent of disease activity and disability at baseline: real-life data from a Swiss cohort Kallweit, U ; Jelcic, I ; Braun, N ; Fischer, H ; Zörner, B ; Schreiner, B ; Sokolov, A A ; Martin, R ; Weller, M ; Linnebank, M Abstract: OBJECTIVES: Therapy for relapsing-remitting multiple sclerosis with natalizumab (Tysabri; Biogen Idec) has been shown to be effective in the reduction of the clinical relapse rate and disability progression. However, real-life longitudinal data, including years before baseline, are rare. METHODS: An observational single-center study was carried out. We analyzed data from 64 consecutive patients with multiple sclerosis. RESULTS: After 1 year of treatment (n = 64), score on the Expanded Disability Status Scale (EDSS) decreased by 0.47 points (P = 0.047) and the annualized relapse rate (ARR) decreased by 82% (P < 0.001). After 2 years (n = 41), EDSS score was still reduced by 0.28 (not significant) and ARR was reduced by 69% (P < 0.001). After 3 years (n = 23), EDSS score was reduced by 0.26 (not significant), and ARR was reduced by 77% (P < 0.001). Reduction of EDSS score andARRdid not depend on baseline ARR (1-2 vs >2) or EDSS score and was not biased by exceptional high disease activity or relapses around baseline. CONCLUSIONS: These real-life data reinforce that natalizumab is effective over years, reduces ARR, and stabilizes EDSS score independent of baseline ARR, baseline EDSS score, or baseline treatment.

  • Multiple Sclerosis Research: Diagnostics, Disease-Modifying
    S14 Journal of Neuroscience Nursing Multiple Sclerosis Research: Diagnostics, Disease-Modifying Treatments, and Emerging Therapies Kathleen Costello ABSTRACT Multiple sclerosis (MS) is a complex disease that affects the central nervous system. It is believed to be an immune mediated disease, and although the etiology remains unknown, it is believed to occur from a combination of genetic risk factors and environmental risk factors. There is no single diagnostic test for MS, and diagnostic criteria have been developed to aid the provider in making an accurate and timely diagnosis. Once a diagnosis of MS is made, treatments directed toward the inflammatory immune response should be initiated. Currently, there are 10 treatments for MS: four interferon beta products; one glatiramer acetate; one monoclonal antibodyVnatalizumab; three oral treatmentsVfingolimod, teriflunomide, and dimethyl fumarate; and one immunosuppressant agentVmitoxantrone. Each of these agents has a different administration and different risks and side effects. Numerous agents are in late stage development, and it is possible that several more agents, all with different mechanisms of action, will become available over the next several years. Keywords: alemtuzumab, daclizumab, dimethyl fumarate, disease modifying treatment, fingolimod, glatiramer acetate, interferon beta, laquinimod, MCDONALD Criteria, multiple sclerosis, natalizumab, teriflunomide ultiple sclerosis (MS) is a chronic disease of the disease from onset, known as primary progres- of the central nervous system

  • COMPARISON of the WHO ATC CLASSIFICATION & Ephmra/Intellus Worldwide ANATOMICAL CLASSIFICATION
    COMPARISON OF THE WHO ATC CLASSIFICATION & EphMRA/Intellus Worldwide ANATOMICAL CLASSIFICATION: VERSION June 2019 2 Comparison of the WHO ATC Classification and EphMRA / Intellus Worldwide Anatomical Classification The following booklet is designed to improve the understanding of the two classification systems. The development of the two systems had previously taken place separately. EphMRA and WHO are now working together to ensure that there is a convergence of the 2 systems rather than a divergence. In order to better understand the two classification systems, we should pay attention to the way in which substances/products are classified. WHO mainly classifies substances according to the therapeutic or pharmaceutical aspects and in one class only (particular formulations or strengths can be given separate codes, e.g. clonidine in C02A as antihypertensive agent, N02C as anti-migraine product and S01E as ophthalmic product). EphMRA classifies products, mainly according to their indications and use. Therefore, it is possible to find the same compound in several classes, depending on the product, e.g., NAPROXEN tablets can be classified in M1A (antirheumatic), N2B (analgesic) and G2C if indicated for gynaecological conditions only. The purposes of classification are also different: The main purpose of the WHO classification is for international drug utilisation research and for adverse drug reaction monitoring. This classification is recommended by the WHO for use in international drug utilisation research. The EphMRA/Intellus Worldwide classification has a primary objective to satisfy the marketing needs of the pharmaceutical companies. Therefore, a direct comparison is sometimes difficult due to the different nature and purpose of the two systems.

The development of animal experimental models, specific for each stage of MS will aid in the design of new drugs specific for the different forms of the disease. Animal models of experimental autoimmune encephalomyelitis successfully reflect the pathophysiological mechanisms of the early phases of MS. However, few models resemble the features of the progressive forms of MS such as cortical demyelination and meningeal inflammation.

Purpose for Class Update: Evidence for the comparative effectiveness of disease modifying drugs (DMDs) for multiple sclerosis (MS) was last reviewed by the Oregon Pharmacy & Therapeutic Committee (P&T) in August 2020 as summarized in a Drug Effectiveness Review Project (DERP) report. This review examines new comparative evidence of DMDs for MS published since 2020 and summarizes the evidence for 2 new DMDs, ofatumumab and ponesimod, approved to treat relapsing forms of MS. Research Questions: 1. What is the comparative effectiveness and efficacy of DMDs for MS? 2. Do DMDs for MS differ in harms? 3. Are there subgroups of patients with MS based on demographics (age, racial or ethnic groups, and gender), socioeconomic status, concomitant medications, severity of disease, or co-morbidities for which one DMD is more effective or associated with fewer adverse events? 4. What is the evidence for efficacy and safety for use of ofatumumab in relapsing MS? 5. What is the evidence for efficacy and safety of ponesimod in relapsing MS ? Author: Deanna Moretz, PharmD, BCPS Conclusions: Multiple Sclerosis Disease-Modifying Drugs No new evidence of comparative efficacy or effectiveness of DMDs approved to treat MS has been published since the last MS class review.
