In this regard, the development of effective therapeutic agents with fundamentally new mechanisms of action that provide increased survival is currently an urgent task. One potential immunotherapeutic target is signaling lymphocyte activation molecules (SLAMs), and the anti-SLAMF7 monoclonal antibody elotuzumab is used in combination with either lenalidomide and dexamethasone (Elo-Rd regimen) after 1 prior line of therapy, or with pomalidomide and dexamethasone (Elo-Pd regimen) after 2 or more lines of therapy. The results of studies demonstrated a survival benefit in all subgroups of patients with refractory or relapsed multiple myeloma when using elotuzumab. A manageable safety profile and a low frequency of grade III–IV induced myelosuppression were noted, which allows the use of elotuzumab in combination with lenalidomide or pomalidomide and dexamethasone in elderly and debilitated patients. We present our own experience of using elotuzumab in the treatment of patients with refractory/recurrent multiple myeloma. A clinical case of a patient in whom treatment with elotuzumab was initiated at an early stage (after 1 line of previous therapy) is presented; the effectiveness and safety of using the monoclonal antibody are assessed. A significant improvement in the patient’s clinical condition and positive dynamics according to laboratory data were noted already during the 1st cycle of Elo-Rd regimen with a further progressive deepening of the antitumor response along with satisfactory tolerability and the absence of significant adverse events.</p></abstract><trans-abstract xml:lang="ru"><p>Несмотря на достигнутые успехи в терапии, во многом обусловленные изучением молекулярной биологии, множественная миелома остается неизлечимым заболеванием, а рефрактерное течение или рецидивы значимо ухудшают прогноз. В связи с этим разработка эффективных терапевтических агентов с принципиально новыми механизмами действия, обеспечивающих увеличение выживаемости, является в настоящее время актуальной задачей. Одна из потенциальных мишеней для иммунотерапевтического воздействия – сигнальные молекулы активации лимфоцитов (signaling lymphocytic activation molecule, SLAM). Моноклональное антитело элотузумаб, направленное против SLAMF7, применяется в комбинации либо с леналидомидом и дексаметазоном (режим Elo-Rd) после 1 предшествующей линии терапии, либо с помалидомидом и дексаметазоном (режим Elo-Pd) после 2 и более линий терапии. Результаты проведенных исследований продемонстрировали преимущество в выживаемости во всех подгруппах пациентов с рецидивами или рефрактерным течением множественной миеломы при применении элотузумаба. Отмечены управляемый профиль безопасности и небольшая частота эпизодов индуцированной миелосупрессии III–IV степеней, что позволяет применять элотузумаб в комбинации с леналидомидом или помалидомидом и дексаметазоном у пожилых и ослабленных больных. представлен собственный опыт использования элотузумаба в терапии больных рефрактерной/рецидивирующей множественной миеломой. приведено клиническое наблюдение пациента, которому лечение элотузумабом было инициировано на раннем этапе (после 1 линии предшествующей терапии), оценены эффективность и безопасность использования моноклонального антитела. Значимое улучшение клинического состояния больного и положительная динамика по лабораторным данным отмечены уже в процессе проведения 1-го цикла лечения в режиме Elo-Rd с дальнейшим прогрессивным углублением противоопухолевого ответа наряду с удовлетворительной переносимостью и отсутствием значимых нежелательных явлений.</p></trans-abstract><kwd-group xml:lang="en"><kwd>refractory/relapsed multiple myeloma</kwd><kwd>elotuzumab</kwd><kwd>lenalidomide</kwd><kwd>dexamethasone</kwd><kwd>stabilization</kwd><kwd>deepening of antitumor response</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>рефрактерная/рецидивирующая множественная миелома</kwd><kwd>элотузумаб</kwd><kwd>леналидомид</kwd><kwd>дексаметазон</kwd><kwd>стабилизация</kwd><kwd>углубление противоопухолевого ответа</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">1.
