Хоффманн-Ля Рош Лтд.», Швейцария).</p><sec><title>Материалы и методы</title><p>Материалы и методы. В исследование включено 40 больных с подтвержденным диагнозом ревматоидный артрит, получивших не менее одного курса оригинального препарата ритуксимаба Мабтера® в дозе 1000 мг дважды с интервалом в 2 недели 6 месяцев назад и более и нуждающихся в продолжении лечения ритукси-мабом. По немедицинским причинам пациенты переключены на биоаналог Ацеллбия®, терапия которым продолжена в аналогичной дозе в течение года на фоне терапии синтетическими базисными противовоспалительными препаратами. На 12-й, 24-й неделях и через год после переключения проведена оценка выраженности боли по визуальной аналоговой шкале (ВАШ), числа болезненных (ЧБС) и припухших (ЧПС) суставов, уровня острофазовых маркеров воспаления, иммунологических маркеров, индекса DAS28-СОЭ, DAS28-СРБ, функционального индекса HAQ, а также безопасности терапии.</p></sec><sec><title>Результаты</title><p>Результаты. Все данные представлены в виде медианы соответствующего показателя. Через 12 недель от введения биоаналога ритуксимаба отмечено значимое снижение ЧБС и ЧПС. Их медианы уменьшились с 9,5 до 6,0 (p&lt;0,01) и с 2,0 до 1,0 (p&lt;0,01) соответственно. Достигнутый эффект сохранялся на 24-й неделе и через год. Отмечалась также аналогичная динамика интенсивности боли по ВАШ. Статистически значимо по сравнению с исходными показателями снижался индекс DAS28-СОЭ — с 4,38 до 3,55 через 24 недели и до 3,49 через год (р &lt;0,01) и DAS28-СРБ - с 3,91 до 3,15 и 3,03 соответственно (р &lt;0,01). Уровень иммунологических маркеров нарастал или оставался неизменным в течение первых месяцев наблюдения после переключения, но в дальнейшем значимо снижался по сравнению с исходными значениями. Так, через год уровень ревматоидного фактора уменьшался с 45,0 до 23,0 Ед/мл (p&lt;0,01), антител к циклическому цитруллинированному пептиду - с 88,0 до 50,5 Ед/мл (р&lt;0,01), индекс HAQ - с 1,00 до 0,75 (p&lt;0,01). После переключения на препарат Ацеллбия® профиль безопасности был сопоставим с оригинальным препаратом, тяжелые инфузионные реакции не наблюдались.</p></sec><sec><title>Заключение</title><p>Заключение. Исследование показало, что немедицинское переключение с оригинального препарата Мабтера® на биоаналог Ацеллбия® не оказало существенного влияния на эффективность и безопасность терапии.</p></sec></abstract><trans-abstract xml:lang="en"><p>Wide usage of biologic disease-modifying anti-rheumatic drugs (DMARDs) biosimilars in clinical practice has greatly increased the availability of biologic therapy for rheumatic patients. Nevertheless, not only economic expediency but efficacy and safety are the key principals of any treatment including biologic DMARDs.</p><sec><title>Objective</title><p>Objective. To investigate the efficacy and safety of switching from the original rituximab (MabThera®, “F. Hoffmann-La Roche Ltd.”, Switzerland) to its biosimilar (Acellbia®, “BIOCAD”, Russia) by non-medical reasons in rheumatoid arthritis patients.</p></sec><sec><title>Subjects and methods</title><p>Subjects and methods. 40 rheumatoid arthritis patients on basic therapy who had taken at least one course of original rituximab (MabThera®) 1000 mg twice in 2 weeks more than 6 months ago were included. They were switched to equal-dose biosimilar (Acellbia®) by non-medical reasons and were observed throughout the year. At 12, 24 weeks and one year after switching dynamics of the next parameters were evaluated: pain level according to visual analogue scale (VAS), tender joint count (TJC), swollen joint count (SJC), acute inflammatory and immunological markers, disease activity score (DAS28) calculated using erythrocyte sedimentation rate (DAS28-ESR) or C-reactive protein (DAS28-CRP), health assessment questionnaire (HAQ) index and safety profile.</p></sec><sec><title>Results</title><p>Results. All the data are presented as median of indicator in the moment of measurement after switching therapy (Meperiod). In 12-week period TJC [(Me]_0=9.50, Me_12=6.0, p&lt; 0.01) and SJC (Me_0=2,0, Me_12=1,0, p&lt;0.01) were decreased with positive dynamics on the 24 and 48 weeks. Also, similar results were observed in the VAS pain level. DAS28 showed significant decreasing during observation: Me0=4.38, Me24=3.55, Meyear=3.49, p&lt;0.01 for DAS28-ESR; and Me0=3.91, Me24=3.15, Meyear=3.03, p&lt;0.01 for DAS28-CRP. Immunological markers were increased or stable during the first months after switching, but then they were significantly decreased: Me0=45.0 U/ml, Meyear=23.0 U/ml, p&lt;0.01 for rheumatoid factor; and Me0=88.0 U/ml, Meyear=50.5 U/ml, p&lt;0.01 for anti-cyclic citrullinated peptide. HAQ index was stabilized during 1 year: Me0=1.00, Meyear=0.75, p&lt;0.01. Severe infusion reactions on Acellbia® were not observed, safety profile was similar to MabThera®.</p></sec><sec><title>Conclusion</title><p>Conclusion. Our investigation revealed that non-medical switching from original rituximab (MabThera®, “F. Hoffmann-La Roche Ltd.”, Switzerland) to its biosimilar (Acellbia®, “BIOCAD”, Russia) has no significant influence on the therapy efficacy and safety.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>ревматоидный артрит</kwd><kwd>биоаналог</kwd><kwd>ритуксимаб</kwd></kwd-group><kwd-group xml:lang="en"><kwd>rheumatoid arthritis</kwd><kwd>biosimilar</kwd><kwd>rituximab</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">работа выполнена за счет средств бюджетного финансирования на выполнение государственного задания по теме № 0324-2019-0046-C-02</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">Dorner T, Burmester GR.
