Patients with spinal muscular atrophy received therapy with onasemnogene abeparvovec based on the prescription of the drug according to vital indications by a council of physicians of Federal institutions (the availability of the drug was carried out within the framework of the MAP Program (global program of managed access MAP to AVXS-101 for eligible patients in countries, where it is not approved by regulatory authorities (NCT03955679), through funding from the charitable foundations, as well as through funding from the state fund “Circle of Kindness”. The drug tolerance was assessed and the analysis of side effects after drug administration was based on the criteria for adverse events (General criteria Adverse Event Terminology (CTCAE) v. 5.0) Patient motor function was assessed prior to treatment initiation and every 3–6 months after therapy using the Philadelphia Pediatric Hospital’s CHOP INTEND scale, total motor development based on Hammersmith Hospital Neurological Assessment Scale in Young Children, Part 2 (HINE-2), and the acquisition of new motor skills.<bold>Results</bold>. 41 children aged 5 to 47 months (weighing no more than 21 kg) received therapy with onasemnogene abeparvovec in the period from April 2020 to December 2021. Adverse events (hyperthermia, decreased appetite, nausea, vomiting) were registered in all patients with different degree of severity. Elevated levels of transaminases greater than 2 times the upper limit of the normal range were observed in 32 patients (78 %), thrombocytopenia in 9 patients (22 %). 15 patients (36 %) required a dose adjustment of corticosteroids.17 patients underwent assessment of motor scales after 6 months, 10 children were assessed after a year. The average improvement on the HINE-2 scale was 3.3 / 4.4 points, respectively. The average improvement on the CHOP INTEND Scale was 7.1 / 9.4 points after 6 / 12 months of therapy.<bold>Conclusion</bold>. The efficacy and safety of onasemnogene abeparvovec have been demonstrated in real clinical practice in the treatment of spinal muscular atrophy for children in different age groups with a body weight of no more than 21 kg.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Цель исследования</bold> – проанализировать безопасность и оценить эффективность терапии препаратом Золгенсма® (онасемноген абепарвовек) у пациентов со спинальной мышечной атрофией в реальной клинической практике на основании опыта применения препарата в нервно-мышечном центре ОСП «Научно-исследовательский клинический институт педиатрии им. акад. Ю. Е. Вельтищева» ФГБОУ ВО РНИМУ им. Н. И. Пирогова.<bold>Материалы и методы</bold>. Пациенты со спинальной мышечной атрофией получали терапию препаратом онасемноген абепарвовек на основании назначения препарата по жизненным показаниям консилиумом врачей федеральных учреждений (доступность к препарату осуществлялась в рамках Программы MAP (глобальная программа управляемого доступа MAP к препарату AVXS-101 для пациентов, соответствующих критериям, в странах, где он не был одобрен регулирующими органами (NCT03955679)), за счет финансирования благотворительных фондов, а также за счет финансирования государственным фондом «Круг добра». Проведены оценка переносимости препарата и анализ побочных эффектов после введения препарата на основании критериев нежелательных явлений (Общие критерии терминологии для нежелательных явлений (CTCAE) v. 5.0). Оценивались моторная функция пациентов до начала терапии и каждые 3–6 мес после терапии с помощью шкалы детской больницы Филадельфии для диагностики двигательных функций у новорожденных (CHOP INTEND), общее двигательное развитие по шкале оценки неврологического статуса больницы Хаммерсмит у детей раннего возраста, часть 2 (HINE-2), а также приобретение новых двигательных навыков.<bold>Результаты</bold>. Терапию препаратом онасемноген абепарвовек получил 41 ребенок в возрасте от 5 до 47 мес (с массой тела не более 21 кг) в период с апреля 2020 г. по декабрь 2021 г. Нежелательные явления (гипертермия, снижение аппетита, тошнота, рвота) зарегистрированы у всех пациентов с разной степенью выраженности. Повышение уровня трансаминаз более чем в 2 раза от верхней границы нормы было отмечено у 32 (78 %) пациентов, тромбоцитопения – у 9 (22 %); 15 (36 %) пациентам потребовалась коррекция дозы кортикостероидов.Семнадцати пациентам проведена оценка по двигательным шкалам через 6 мес, 10 детям – спустя год. Среднее улучшение по шкале HINE-2 составило 3,3 / 4,4 балла соответственно. Среднее улучшение по шкале CHOP INTEND составило 7,1 / 9,4 балла через 6 / 12 мес терапии.<bold>Заключение</bold>. Продемонстрированы эффективность и безопасность применения препарата онасемноген абепарвовек в условиях реальной клинической практики при терапии спинальной мышечной атрофии для детей в разных возрастных группах с массой тела не более 21 кг.</p></trans-abstract><kwd-group xml:lang="en"><kwd>spinal muscular atrophy</kwd><kwd>onasemnogene abeparvovec</kwd><kwd>Zolgensma®</kwd><kwd>safety</kwd><kwd>MAP program</kwd><kwd>increased transaminases</kwd><kwd>SMN1 gene</kwd><kwd>gene replacement therapy</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>спинальная мышечная атрофия</kwd><kwd>онасемноген абепарвовек</kwd><kwd>Золгенсма®</kwd><kwd>безопасность</kwd><kwd>программа MAP</kwd><kwd>повышение уровня трансаминаз</kwd><kwd>ген SMN1</kwd><kwd>генозаместительная терапия</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Verhaart E.C., Robertson A., Wilson I.J. et al.
