При фармацевтической разработке российских препаратов генной терапии на основе аденоассоциированных вирусов (AAV) необходимым этапом является создание стандартных образцов (СО), которые используются на протяжении всего цикла разработки препарата, а также установление стабильности СО при хранении. В качестве материала для СО AAV 9 серотипа (AAV9) может выступать препарат пустых капсидов AAV9.ЦЕЛЬ. Разработка методик оценки физико-химических показателей качества для характеристики стандартного образца пустых капсидов AAV9 и исследование его стабильности при хранении.МАТЕРИАЛЫ И МЕТОДЫ. Наработку СО пустых капсидов AAV9 проводили в суспензионных клетках HEK293 с использованием бессывороточной среды при оптимизированных параметрах трансфекции с последующим осветлением, концентрированием, хроматографической очисткой AAV9 на аффинном сорбенте (AAVX) и диафильтрацией. Для анализа образцов применяли электрофорез, трансмиссионную электронную микроскопию, иммуноферментный анализ (ИФА), эксклюзионную хроматографию, динамическое светорассеяние, спектрофотометрию и биослойную интерферометрию. Определение концентрации капсидов проводили методом ИФА. Для разработки методов оценки физического титра использовали СО AAV с известным титром. При исследовании стабильности СО хранили при –80 °C в течение 9 мес.РЕЗУЛЬТАТЫ. Наработанный СО AAV9 обладал высокой степенью чистоты по результатам эксклюзионной хроматографии — содержание мономеров вирусных капсидов составляло не менее 98%. С использованием методов динамического светорассеяния, эксклюзионной хроматографии и электронной микроскопии показано отсутствие агрегатов в образце. Установлена стабильность полученного СО пустых капсидов AAV9 в течение 9 мес. Показано, что при определении физического титра СО пустых капсидов AAV9 оптимальными для рутинного анализа качества являются методы динамического рассеяния света и спектрофотометрии; метод биослойной интерферометрии рекомендуется для регулярного анализа. Определенные тремя указанными методами значения титра вирусных частиц варьировали от 1,48×10¹³ до 5,6×10¹³.ВЫВОДЫ. Разработан стандартный образец пустых капсидов AAV9, который может быть пригоден для контроля качества препаратов генной терапии на основе AAV9.</p></abstract><trans-abstract xml:lang="en"><p>INTRODUCTION. The development of adeno-associated virus (AAV)-based gene therapy products in Russia requires establishing reference standards, which are used throughout the pharmaceutical development cycle, and monitoring their stability during the storage period. A preparation of empty capsids of AAV serotype 9 (AAV9) is an appropriate material for a reference standard for empty AAV9 capsids (AAV9 RS).AIM. This study aimed to develop analytical procedures to evaluate the AAV9 RS physicochemical quality parameters for its characterisation and to study its storage stability.MATERIALS AND METHODS. Empty AAV9 capsids were produced in HEK293 suspension culture using serum-free medium and optimised transfection parameters. The next steps involved AAV9 clarification, concentration, and purification by affinity chromatography with AAVx resin and diafiltration. The analysis of AAV9 samples used electrophoresis, transmission electron microscopy, enzyme-linked immunosorbent assay (ELISA), size-exclusion chromatography, dynamic light scattering, spectrophotometry, and bio-layer interferometry. The concentration of capsids was measured by ELISA. Analytical procedures for physical titre determination were developed using an AAV9 standard with a known physical titre. The stability study of the AAV9 RS involved storage at –80 °C for 9 months.RESULTS. Size-exclusion chromatography demonstrated the high purity of the established AAV9 RS, with at least 98% content of the viral capsid monomer. Dynamic light scattering, size-exclusion chromatography, and electron microscopy confirmed that the AAV9 RS was free of aggregates. The stability study showed that the AAV9 RS remained stable for 9 months. Dynamic light scattering and spectrophotometry were deemed optimal methods for routine quality analysis measuring the AAV9 RS physical titre, and bio-layer interferometry was recommended for regular analysis. The viral particle titres determined by these methods ranged from 1.48×1013 to 5.6×1013.CONCLUSIONS. The AAV9 RS established in this study is suitable for quality control of AAV9-based gene therapy products.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>аденоассоциированный вирус</kwd><kwd>AAV</kwd><kwd>пустой капсид</kwd><kwd>генная терапия</kwd><kwd>генотерапевтический преперат</kwd><kwd>фармацевтическая разработка</kwd><kwd>методы контроля качества</kwd><kwd>стандартный образец</kwd><kwd>HEK293</kwd><kwd>аффинная хроматография</kwd><kwd>физический титр капсидов</kwd><kwd>стабильность стандартного образца</kwd></kwd-group><kwd-group xml:lang="en"><kwd>adeno-associated virus</kwd><kwd>AAV</kwd><kwd>empty capsid</kwd><kwd>gene therapy</kwd><kwd>gene therapy product</kwd><kwd>pharmaceutical development</kwd><kwd>quality control methods</kwd><kwd>reference standard</kwd><kwd>HEK293</kwd><kwd>affinity chromatography</kwd><kwd>physical capsid titre</kwd><kwd>reference standard stability</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Финансирование проекта осуществлялось Министерством науки и высшего образования Российской Федерации (Соглашение № 075-10-2021-093; проект GTH-RND-2112).</funding-statement><funding-statement xml:lang="en">The study was funded by the Ministry of Science and Higher Education of the Russian Federation (Agreement No. 075-10-2021-093, Research Project No. GTH-RND-2112).</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">Minskaia E, Galieva A, Egorov AD, Karabelsky AV.
