The disease is characterized by early onset of muscle weakness in the proximal limbs, loss of the ability to walk independently, followed by damage to respiratory and cardiac functions, and premature death of patients in the second or third decade of life.</p> <p>Until recently, patients were prescribed only symptomatic treatment aimed at slowing down the progression of the disease. Currently, several pathogenetic drugs have appeared aimed at restoring the synthesis of the dystrophin protein (microdystrophin). One of them, delandistrogen moxparvovec, is gene therapy drug based on a recombinant adeno-associated virus (AAVhr74).</p> <p>The article presents the experience of using Delandistrogen moxparvovec in 17 patients with Duchenne muscular dystrophy aged 5 years 8 months to 9 years and 1 months. Preliminary data indicate a possible slowdown in the progression of the disease, which is manifested in stabilization or improvement of motor functions. In all patients, the use of this drug was safe, there were no adverse events associated with this therapy.</p></abstract><trans-abstract xml:lang="ru"><p>Прогрессирующая мышечная дистрофия Дюшенна – тяжелое X-сцепленное наследственное нервно-мышечное заболевание. Оно обусловлено мутациями в гене <italic>DMD,</italic> кодирующем белок дистрофин. Заболевание характеризуется ранним началом мышечной слабости в проксимальных отделах конечностей, потерей способности к самостоятельной ходьбе с последующим поражением дыхательной и сердечной функций и преждевременной смертью пациентов во II или III декаде жизни.</p> <p>До недавнего времени пациентам назначали только симптоматическое лечение, направленное на замедление прогрессирования заболевания. В настоящее время появилось несколько патогенетических лекарственных препаратов, направленных на восстановление синтеза белка дистрофина (микродистрофина). Один из них, деландистроген моксепарвовек, представляет собой терапевтическое средство на основе нереплицирующегося рекомбинантного аденоассоциированного вируса AAVhr74.</p> <p>В статье представлен опыт применения препарата деландистроген моксепарвовек у 17 пациентов с мышечной дистрофией Дюшенна в возрасте от 5 лет 8 мес до 9 лет 1 мес. Предварительные данные указывают на возможное замедление прогрессирования болезни, что проявляется стабилизацией или улучшением двигательных функций. У всех пациентов применение данного препарата было безопасным, не выявлено серьезных нежелательных явлений, связанных с его применением.</p></trans-abstract><kwd-group xml:lang="en"><kwd>delandistrogene moxeparvec</kwd><kwd>microdystrophin</kwd><kwd>gene therapy</kwd><kwd>DMD</kwd><kwd>North Star Ambulatory Assessment</kwd><kwd>safety</kwd><kwd>efficacy</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>деландистроген моксепарвовек</kwd><kwd>микродистрофин</kwd><kwd>генная терапия</kwd><kwd>DMD</kwd><kwd>шкала Северная звезда</kwd><kwd>безопасность</kwd><kwd>эффективность</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Clinical Guidelines “Progressive Duchenne muscular dystrophy.
