Цель работы: провести комплексное исследование сопоставимости физико-химических и биологических характеристик лекарственного препарата Ревелиза® и референтного препарата Актилизе® для оценки их биоподобия. Материалы и методы: сравнительное пептидное картирование с определением сопоставимости хроматографических профилей триптических гидролизатов проводилось методами ОФ-ВЭЖХ и масс-спектрометрии, определение молекулярно-массового распределения — методами масс-спектрометрии и электрофореза в полиакриламидном геле по Леммли. Для определения чистоты и гомогенности препаратов, а также содержания родственных примесей (олигомеров, фрагментов) использовали метод гель-фильтрации; исследование профиля N-гликозилирования осуществляли методом гидрофильной ВЭЖХ, определение тотального содержания сиаловых кислот — методом Свеннерхольма. Оценку связывания белка с фибрином и фибриногеном человека проводили методом поверхностного плазмонного резонанса, сравнение специфической активности — методом лизиса фибринового сгустка. Результаты: в ходе исследований было продемонстрировано полное совпадение пептидных карт анализируемых препаратов, что свидетельствует об идентичности аминокислотной последовательности алтеплазы в составе сравниваемых препаратов. Также сравнительно были определены молекулярная масса и содержание интактной одноцепочечной формы белка в лекарственных препаратах, количественно охарактеризованы посттрансляционные модификации, содержание сиаловых кислот и нейтральных сахаров. При изучении профиля N-гликозилирования обнаружены незначительные различия в процентном содержании мультиантенных комплексных гликанов. Специфичность алтеплазы оценивали при образовании белковых комплексов с природными лигандами алтеплазы — фибрином и ингибитором активатора плазминогена первого типа, при этом достоверных различий обнаружено не было. При сравнении специфической активации фибринолитической активности плазминогена в тесте на скорость лизиса фибринового сгустка была продемонстрирована сопоставимость препаратов Ревелиза® и Актилизе®. Выводы: проведенные сравнительные экспериментальные исследования показали отсутствие различий в структуре, гетерогенности распределения зарядов, содержании примесей, а также специфической активности алтеплазы в составе лекарственного препарата Ревелиза® и референтного препарата Актилизе®, что позволяет сделать вывод о сопоставимости препаратов по физико-химическим и биологическим свойствам.</p></abstract><trans-abstract xml:lang="en"><p>Recombinant tissue plasminogen activator (international nonproprietary name — alteplase) which was developed by «GENERIUM» (Russia) and received a marketing authorisation in Russia is completely analogous to Actilyse® which is used to treat medical conditions accompanied by thrombosis, such as acute myocardial infarction, pulmonary embolism, and ischemic stroke. The aim of the study was to carry out a comprehensive comparison of physico-chemical and biological properties of Revelyse® and the reference product Actilyse® in order to assess their biosimilarity. Materials and Methods: comparative peptide mapping and determination of comparability of chromatographic profiles of tryptic hydrolysates was performed using RP-HPLC and massspectrometry; the molecular weight distribution was determined by mass-spectrometry and polyacrylamide gel electrophoresis (Laemmli method). The purity and homogeneity of products as well as the content of related impurities (oligomers and fragments) were determined using gel filtration; N-glycosylation profile was analysed by hydrophilic HPLC, total sialic acid was quantified by the Svennerholm resorcinol method. Protein binding to fibrin and human fibrinogen was assessed by surface plasmon resonance, and the specific activity was compared by fibrin clot lysis. Results: the research demonstrated a complete overlap of the products’ peptide maps, which indicates the identity of аlteplase amino acid sequences in the two medicines being compared. The authors of the study also determined the molecular weight and the content of the intact single-stranded form of the protein, and quantified post-translational modifications, the content of sialic acids and neutral sugars. The analysis of the N-glycosylation profile revealed insignificant differences in the percentage of multiantenna complex glycans. The specificity of alteplase was evaluated by analysing the formation of protein complexes with natural alteplase ligands – fibrin and plasminogen activator inhibitor-1, but no significant differences were found. The comparison of specific activation of plasminogen fibrinolytic activity was performed based on the results of the assay analysing the fibrin clot lysis rate, and it demonstrated comparability of Revelyse® and Actilyse®. Conclusions: comparative experimental studies have shown no differences in the structure, charge distribution heterogeneity, impurities content, and specific activity of alteplase as a component of Revelyse® and the reference product Actilyse®, which leads to the conclusion that they are similar in terms of physicochemical and biological properties.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>тканевый активатор плазминогена</kwd><kwd>биоаналог</kwd><kwd>Актилизе®</kwd><kwd>Ревелиза®</kwd><kwd>профиль гликозилирования</kwd><kwd>посттрансляционные модификации</kwd><kwd>лизис фибринового сгустка</kwd></kwd-group><kwd-group xml:lang="en"><kwd>tissue plasminogen activator</kwd><kwd>biosimilar</kwd><kwd>Actilyse®</kwd><kwd>Revelyse®</kwd><kwd>glycosylation profile</kwd><kwd>post-translational modifications</kwd><kwd>fibrin clot lysis</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Выражаем благодарность всему коллективу отдела аналитических методов МБЦ «ГЕНЕРИУМ» за советы и поддержку в работе над проектом.
