In 2020, fremanezumab, a new calcitonin gene-related peptide monoclonal antibody was authorized in Russia.</p> <p><bold><italic>Objective:</italic></bold> to evaluate safety and effectiveness of fremanezumab in patients with high-frequency episodic migraine (HF EM) and chronic migraine (CM).</p> <p><bold><italic>Materials and methods. </italic></bold>We assessed 60 patients at the age of 35.5 ± 8.96 years (85%, females) with HFEM and CM with and without aura who were either receiving preventive treatment or not. Fremanezumab was administered subcutaneously at a single dose of 675 mg. The study participants were followed-up for efficacy in 3 months. The investigators assessed change in the number of days with headache per month as well as headache intensity, its impact on the daily activities, anxiety, and depression.</p> <p><bold><italic>Results. </italic></bold>By the end of month 3 post dosing, the number of days with headache decreased by &gt;50% in 76.7% of participants where 77.8% of individuals suffered from HF EM and 72.7% of individuals had CM while headache intensity decreased in all the patients equally. No response (decrease in the number of days with headache by &lt; 30%) was reported in 15% of participants including 14.8% of individuals with HF EM and 15.2% of individuals with CM. By the end of study month 3, 81% of participants demonstrated no anxiety symptoms and 79% of participants showed no depression with significant MIDAS and HIT-6 score decline in both groups. Only 3 (5%) patients noted adverse events (redness, itching at the administration site).</p> <p><bold><italic>Conclusion.</italic></bold> We documented higher fremanezumab safety and effectiveness in patients with EM and CM in real-world practice as compared to fremanezumab safety and efficacy in randomized clinical trials. A single dose of fremanezumab (675 mg) resulted in effective migraine prevention, decline in comorbid anxiety and depression, and improved quality of life during 3-month follow-up.</p></abstract><trans-abstract xml:lang="ru"><p><bold><italic>Введение.</italic></bold> Высокая распространённость мигрени, её негативное влияние на качество жизни обосновывают разработку оригинальных препаратов. В 2020 г. в России для лечения мигрени зарегистрирован препарат фреманезумаб — моноклональное антитело к кальцитонин-ген-родственному пептиду.</p> <p><bold><italic>Цель</italic></bold> исследования — оценить эффективность и безопасность фреманезумаба у пациентов с частой эпизодической (ЭМ) и хронической (ХМ) мигренью.</p> <p><bold><italic>Материал и методы.</italic></bold> Обследованы 60 пациентов в возрасте 35,5 ± 8,96 года (85% — женщины) с частой ЭМ и ХМ с аурой и без ауры, ранее получавшие и не получавшие профилактическое лечение. Пациентам проведено однократное подкожное введение 675 мг фреманезумаба с оценкой эффективности через 3 мес. Учитывали изменение количества дней с головной болью в месяц и её интенсивности, влияние на повседневную активность, тревогу и депрессию.</p> <p><bold><italic>Результаты. </italic></bold>К концу 3-го месяца после введения фреманезумаба снижение числа дней с ГБ в месяц &gt; 50% произошло у 76,7% пациентов: у 77,8% с частой ЭМ, у 72,7% с ХМ; интенсивности головной боли — у всех пациентов в равной степени. Не ответили на лечение фреманезумабом (число дней с ГБ в месяц снизилось &lt; 30%) 15% пациентов: 14,8% с частой ЭМ и 15,2% с ХМ. К концу 3-го месяца исследования отсутствие симптомов тревоги продемонстрировали 81% пациентов, депрессии — 79%, значительное снижение уровня инвалидизации по шкале MIDAS и опроснику HIT-6 отмечено у большинства пациентов обеих групп. Лишь 3 (5%) пациента отметили нежелательные явления в виде покраснения и зуда в месте инъекции препарата.</p> <p><bold><italic>Заключение. </italic></bold>Настоящее исследование реальной клинической практики установило более высокую эффективность и безопасность фреманезумаба в лечении ЭМ и ХМ, чем в рандомизированных клинических исследованиях. Однократное введение 675 мг фреманезумаба обеспечивало на протяжении 3 мес наблюдения эффективную профилактику мигрени, снижение коморбидных тревоги и депрессии, улучшение качества жизни.</p></trans-abstract><kwd-group xml:lang="en"><kwd>migraine</kwd><kwd>monoclonal antibodies</kwd><kwd>CGRP</kwd><kwd>fremanezumab</kwd><kwd>clinical practice</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>мигрень</kwd><kwd>моноклональные антитела</kwd><kwd>CGRP</kwd><kwd>фреманезумаб</kwd><kwd>клиническая практика</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>GBD 2016 Headache Collaborators.
