Гиперэкспрессия EGFR на клетках опухолей эпителиального происхождения является известным фактом, что обусловливает выбор данного рецептора в качестве мишени для препаратов терапевтических моноклональных антител. Основным механизмом действия данных препаратов является блокирование пролиферации эпителиальных клеток вследствие связывания с EGFR. В рамках экспериментов in vivo была проведена оценка динамики роста опухоли у иммунодефицитных мышей Nu/Nu по двум показателям: индексу прироста опухоли и торможению роста опухоли (ТРО, %). Полученные при использованной схеме эксперимента результаты свидетельствуют о том, что исследуемые препараты производства ЗАО «Биокад» и коммерческий препарат «Эрбитукс®» обладают сопоставимой выраженностью противоопухолевого эффекта, оценённого по значениям ТРО и индекса прироста опухоли.</p></abstract><trans-abstract xml:lang="en"><p>This article presents the results of the comparative antitumor efficacy study of two test articles of therapeutic humanized monoclonal antibodies against epidermal growth factor receptor (EGFR) manufactured by Russian biopharmaceutical company CJSC “Biocad” and the commercial drug “Erbitux®” (Merck, Germany) in subcutaneous xenografts model using human epidermoid carcinoma A431NS cell line. EGFR overexpression in epithelial tumor cells is a commonly known fact that determines use of this receptor as a target for therapeutic monoclonal antibodies. The basic mechanism of action of such drugs is blocking of epithelial cells proliferation through competitive binding to EGFR. Evaluation of tumor growth dynamics in immunodeficient (Nu/Nu) mice was performed during in vivo experiment using two parameters: tumor growth index and tumor growth inhibition (TGI, %). The results received with used study design show that antitumor effects of the test articles manufactured by CJSC “Biocad” and the commercial comparator drug “Erbitux®” estimated by values of TGI and tumor growth index are comparable.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>A431NS</kwd><kwd>Эрбитукс®</kwd><kwd>Ксенографт</kwd><kwd>иммунодефицитные мыши</kwd><kwd>торможение роста опухоли</kwd><kwd>противоопухолевая эффективность</kwd><kwd>эпидермоидная карцинома человека</kwd><kwd>индекс прироста опухоли</kwd></kwd-group><kwd-group xml:lang="en"><kwd>A431NS</kwd><kwd>Erbitux®</kwd><kwd>Xenograft</kwd><kwd>immunodeficient mice</kwd><kwd>Tumor growth inhibition</kwd><kwd>antitumor efficacy</kwd><kwd>human epidermoid carcinoma</kwd><kwd>Tumor growth index</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Беленький М.Л.
