A population-based cohort study was conducted in 54 patients with RRMS who received cladribine tablets.</p><sec><title>Objective</title><p>Objective: to evaluate our own experience of treating patients with highly active MS (HAMS) with cladribine tablets in real-life clinical practice in the MS Centre of the Khanty-Mansi Autonomous Area (KhMAA) — Yugra.</p></sec><sec><title>Material and methods</title><p>Material and methods. The data source is the register of MS patients of the KhMAA — Yugra. Cladribine tablets at a dose of 3.5 mg/kg of body weight were prescribed in two annual treatment cycles, each comprising 2 weeks with a treatment duration of 4—5 days — at the beginning of the first month and at the beginning of the second month. In 2021—2023, 54patients received therapy with cladribine tablets with an average frequency of exacerbations of 1.2 (62 exacerbations in 48 patients) within 12 months prior to therapy initiation. Before starting therapy and every 6 months thereafter, patients underwent magnetic resonance imaging (MRI) of the brain, cervical and thoracic regions MRI with contrast enhancement, assessment of neurological status using the Expanded Disability Status Scale (EDSS), complete blood count, monitoring of blood lymphocytes level and biochemical blood testing. After the first and second treatment courses with cladribine tablets, the lymphocyte level was assessed after 2 months and after 6 months.</p></sec><sec><title>Results</title><p>Results. It was found that the average frequency of exacerbations before the start of treatment was 1.2 per year; after treatment with cladribine tablets it was 0.05 per year, i.e. the average annual frequency of exacerbations fell by 92% in the first year of treatment. Before starting treatment with cladribine tablets, only six (11%) out of 54 patients had no exacerbations; after starting the treatment with cladribine tablets, 48 (89.5%) patients had no exacerbations. The results obtained exceed the results of the CLARITY study, in which the proportion of patients without exacerbations in the cladribine group was 79.7%. In addition, all patients had no disease activity on MRI after starting cladribine therapy compared to the baseline data before starting cladribine therapy, when Gd+ lesions were detected on T1-weighted images in 50 (92.5%) patients. There was also no increase in disability. The mean EDSS score remained stable (median 3.0) or decreased by 0.5—1 point. At the end of follow-up period, 49 (92%) out of 54 patients included in the analysis achieved NEDA-3 status. No adverse events were observed during patient follow-up.</p></sec><sec><title>Conclusion</title><p>Conclusion. The experience with the use of cladribine in KhMAA is consistent with data from real-world clinical practice around the world in terms of efficacy, safety and results of randomized clinical trials. Cladribine tablets are a highly effective and safe treatment for HAMS. Further monitoring of patients is required to assess the long-term benefits and risks of cladribine.</p></sec></abstract><trans-abstract xml:lang="ru"><p>Кладрибин — таблетированный препарат для лечения ремиттирующего рассеянного склероза (РРС), применяемый в качестве терапии иммунореконституции. Проведено популяционное когортное исследование с участием 54 пациентов с РРС, получавших кладрибин в таблетках.</p><p>Цель исследования - оценка собственного опыта лечения пациентов с высокоактивным РС (ВАРС) кладрибином в таблетках в реальной клинической практике центра РС Ханты-Мансийского автономного округа (ХМАО) — Югры.</p><sec><title>Материал и методы</title><p>Материал и методы. Источником данных является реестр пациентов с РС ХМАО-Югры. Таблетки кладрибина в дозе 3,5 мг/кг массы тела назначались двумя ежегодными курсами лечения, каждый из которых включает 2 нед лечения продолжительностью 4—5 дней — в начале первого месяца и в начале второго месяца. В 2021—2023 гг. терапию кладрибином в таблетках получили 54 пациента со средней частотой обострений за 12 мес до начала терапии 1,2 (62 обострения у48 пациентов). До начала терапии и каждые последующие 6 мес пациентам проводили магнитно-резонансную томографию (МРТ) головного мозга, шейного и грудного отделов с контрастным усилением, оценку неврологического статуса по Расширенной шкале инвалидизации (Expanded Disability Status Scale, EDSS), клинический анализ крови, контроль уровня лимфоцитов крови, биохимический анализ крови. После первого и второго курсов лечения кладрибином в таблетках оценивали уровень лимфоцитов через 2 мес и через 6 мес.</p></sec><sec><title>Результаты</title><p>Результаты. Показано, что средняя частота обострений до начала терапии составляла 1,2 в год; после лечения кладрибином в таблетках она составила 0,05 в год, т.е. среднегодовая частота обострений снизилась на 92% уже на первом году лечения. До инициации терапии кладрибином в таблетках только шесть пациентов (11%) из 54 не имели обострений, после начала терапии кладрибином в таблетках обострений не было у 48 (89,5%) пациентов. Полученные результаты превосходят результаты исследования CLARITY, в котором доля пациентов без обострений в группе кладрибина составила 79,7%. При этом у всех пациентов после начала терапии кладрибином отсутствовала активность заболевания по данным МРТ по сравнению с исходными данными — до начала терапии кладрибином, когда у 50 (92,5%) пациентов были выявлены Gd+ очаги на Т1-взвешенных изображениях. Также не отмечалось усиления инвалидизации. средний балл EDSS оставался стабильным (медиана — 3,0) или уменьшился на 0,5—1 балл. К концу наблюдения у 49 (92%) из 54 пациентов, включенных в анализ, был достигнут статус NEDA-3. За время наблюдения за пациентами никаких нежелательных явлений не наблюдалось.</p></sec><sec><title>Заключение</title><p>Заключение. Опыт применения кладрибина в ХМАО соответствует данным реальной клинической практики в мире по эффективности, безопасности и результатам рандомизированных клинических исследований. Кладрибин в таблетках является высокоэффективным и безопасным методом лечения ВАРС. Для оценки долгосрочной пользы и риска применения кладрибина необходимо дальнейшее наблюдение за пациентами.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>высокоактивный рассеянный склероз</kwd><kwd>ремиттирующее течение</kwd><kwd>кладрибин</kwd><kwd>иммунореконституция</kwd></kwd-group><kwd-group xml:lang="en"><kwd>highly active multiple sclerosis</kwd><kwd>relapsing-remitting course</kwd><kwd>cladribine</kwd><kwd>immune reconstitution</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Статья спонсируется компанией «Мерк».</funding-statement><funding-statement xml:lang="en">The article is sponsored by Merck.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Клинические рекомендации.
