Метаболический синдром – мультифакторный комплекс метаболических нарушений, сопровождающийся сахарным диабетом 2 типа и абдоминальным ожирением. В фармакологической коррекции ожирения и сахарного диабета 2 типа наибольший эффект демонстрируют двойные агонисты глюкагоноподобного пептида-1 (GLP-1) и глюкозозависимого инсулинотропного полипептида (GIP), в частности тирзепатид. Оригинальный препарат («Мунджаро», мнн: тирзепатид) не зарегистрирован в Евразийском экономическом союзе (ЕАЭС), что ограничивает его доступность для пациентов и приводит к необходимости разработки отечественного дженерика.</p></sec><sec><title>Цель</title><p>Цель. Проведение физико-химической и биологической характеризации препарата Седжаро® (GP30931) в сравнении с оригинальным препаратом Мунджаро® для установления их сопоставимости.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Исследованы три серии каждого препарата (раствор для подкожного введения, 25 мг/мл). Первичную структуру проверяли с помощью высокоэффективной жидкостной хроматографии в сочетании с масс спектрометрией (ВЭЖХ-МС), пептидного картирования и ЯМР (2D-ЯМР-1H-1H TOCSY). Вторичную структуру, структуры высшего порядка и агрегацию оценивали методами кругового дихроизма (КД), ядерного магнитного резонанса высокого разрешения (ЯМР), квантового выхода флуоресценции (КФ) и динамического рассеяния света (DLS). Профиль примесей анализировали с использованием эксклюзионной и обращенно фазовой ВЭЖХ. Функциональную активность определяли в клеточных тестах по активации кальциевых потоков через рецепторы GLP-1 и GIP с оценкой полумаксимальной эффективной концентрации (EC50); эквивалентность подтверждали методом двух односторонних тестов (TOST, 90 % доверительный интервал).</p></sec><sec><title>Результаты и обсуждение</title><p>Результаты и обсуждение. ВЭЖХ-МС и картирование подтвердили идентичные массу (4 810,52 Да) и аминокислотную последовательность. Спектры ЯМР, профили КД и КФ, а также ДЛС полностью совпадали, что позволяет заключить, что вторичные и третичные структуры препаратов структурно идентичны. Содержание всех видов примесей у GP30931 не превышало значений «Мунджаро». Различие значений EC50 для активации GLP-1 и GIP рецепторов составило ≤5 %, сравнительная биологическая активность находились в пределах 0,80–1,25.</p></sec><sec><title>Заключение</title><p>Заключение. Комплекс проведенных исследований с использованием ортогональных методов показал, что «Седжаро» (GP30931) и «Мунджаро» структурно идентичны, сопоставимы по профилю примесей и биологически эквивалентны. Полученные данные вносят значимый вклад в научное обоснование эквивалентности воспроизведенного препарата тирзепатида и референтного оригинального препарата, тем самым обеспечивая надежную основу для дальнейшей регистрации и клинического применения Седжаро® без проведения дополнительных клинических исследований.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Metabolic syndrome is a multifactorial complex of metabolic disorders accompanied by type 2 diabetes mellitus and abdominal obesity. In the pharmacological correction of obesity and type 2 diabetes mellitus, the greatest effect is demonstrated by dual agonists of glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP), in particular tirzepatide. The original drug (Mundjaro, pln: tirzepatide) is not registered in the Eurasian Economic Union (EAEU), which limits its availability to patients and leads to the need to develop a domestic generic.</p></sec><sec><title>Aim</title><p>Aim. Conducting a physicochemical and biological characterization of the drug Sejaro® (GP30931) in comparison with the original drug Mundjaro® to establish their comparability.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. Three batches of each drug (solution for subcutaneous administration, 25 mg/ml) were studied. The primary structure was verified using high-performance liquid chromatography coupled with mass spectrometry (HPLC-MS), peptide mapping and NMR (2D-NMR-1H-1H TOCSY). Secondary structure, higher order structures and aggregation were assessed by circular dichroism (CD), high-resolution nuclear magnetic resonance (NMR), fluorescence quantum yield (FQY) and dynamic light scattering (DLS). Impurity profiles were analyzed using size-exclusion and reversed-phase HPLC. Functional activity was determined in cellular tests for activation of calcium currents through GLP-1 and GIP receptors with an assessment of the half-maximal effective concentration (EC50); equivalence was confirmed by the two-sided test (TOST, 90 % confidence interval).</p></sec><sec><title>Results and discussion</title><p>Results and discussion. HPLC-MS and mapping confirmed identical mass (4,810.52 Da) and amino acid sequence. NMR spectra, CD and CF profiles, and DLS were completely consistent, which allows us to conclude that the secondary and tertiary structures of the preparations are structurally identical. The content of all types of impurities in GP30931 did not exceed the Munjaro values. The difference in EC50 values for activation of GLP-1 and GIP receptors was ≤5 %, the comparative biological activity was within 0.80–1.25.</p></sec><sec><title>Conclusion</title><p>Conclusion. The complex of studies conducted using orthogonal methods showed that "Sejaro" (GP30931) and "Mundjaro" are structurally identical, comparable in impurity profile and biologically equivalent. The obtained data make a significant contribution to the scientific substantiation of the equivalence of the reproduced drug tirzepatide and the reference original drug, thereby providing a reliable basis for further registration and clinical use of Sejaro® without conducting additional clinical studies.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>тирзепатид</kwd><kwd>GLP-1</kwd><kwd>GIP</kwd><kwd>воспроизведенный пептид</kwd><kwd>физико химическая характеризация</kwd><kwd>ЯМР</kwd><kwd>дженерик</kwd></kwd-group><kwd-group xml:lang="en"><kwd>tirzepatide</kwd><kwd>GLP-1</kwd><kwd>GIP</kwd><kwd>recombinant peptide</kwd><kwd>physicochemical characterization</kwd><kwd>NMR</kwd><kwd>generic</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Спонсор данного исследования – ООО «ГЕРОФАРМ».</funding-statement><funding-statement xml:lang="en">The sponsor of this study is LLC "GEROPHARM".</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">Hirode G., Wong R.
