The number of patients and the cost of drugs are increasing, leading to an increased MS societal burden. However, treatment costs can be reduced due to the introduction of generic drugs, including domestic ones, which price is significantly lower.</p><sec><title>Objective</title><p>Objective: to assess the attitude of Russian patients to the reproduced disease modifying therapies (DMTs) and features influencing an attitude to the replacement from the original to the reproduced drug.</p></sec><sec><title>Patients and methods</title><p>Patients and methods. We interviewed 300 patients from six regions of the Russian Federation, receiving interferon beta-1a 44 μg, interferon beta-1b, glatiramer acetate, and teriflunomide, who had an experience of switching from an original drug to a domestic biosimilar drug or generic not earlier than 2009.</p></sec><sec><title>Results and discussion</title><p>Results and discussion. The majority of patients (63%) do not notice any changes due to drug replacement from the original to the generic one, some (28%) experience a deterioration in their well-being, and others (7%) experience an improvement in their condition. Young patients (up to 30 years) are relatively less likely to notice a deterioration in well-being after drug replacement. The clinical deterioration after drug replacement is much more often experienced by the patients whose drug was replaced in a pharmacy (74% of cases) and not by the attending clinician (only 54% of cases of deterioration). The majority (87%) of patients with relapsing-remitting MS (RRMS) did not interrupt the treatment after replacement; 13% of respondents reported that they had stopped taking the drug. Among them, there were much more patients whose drug was replaced in a pharmacy, and not due to clinician recommendation (more than 80% of such cases). Adverse reactions to a new drug are another reason for drug withdrawal (20% of all withdrawals). Patients receiving interferon beta-1b have a higher negative attitude towards domestic DMTs: 52% of the respondents gave negative feedback (compared to 20–35% in other groups). Relatively higher loyalty to Russian DMTs was observed in patients receiving interferon beta-1a (20% of negative feedback, which is noticeably lower than in other groups) and teriflunomide (a relatively higher proportion of positive feedback to Russian drugs – 25% compared to 11–16% in other groups). The majority (76%) of the respondents noted that they are interested in learning more about the development and registration of new Russian drugs.</p></sec><sec><title>Conclusion</title><p>Conclusion. The majority of RRMS patients do not tend to have a negative attitude towards Russian DMTs. Consequently, the proportion of ratings in favor of Russian DMTs exceeds the weight of ratings against them. The key priority in the formation of loyalty to Russian DMTs should be changing the perception of adverse reactions. This will significantly increase the adherence to therapy and the quality of the provided treatment.</p></sec></abstract><trans-abstract xml:lang="ru"><p>Проблема адекватного выбора метода лечения рассеянного склероза (РС) остается одной из наиболее актуальных в современной неврологии. Количество пациентов и стоимость препаратов увеличиваются, что приводит к нарастанию «бремени» РС для общества. Снижение стоимости лечения возможно при внедрении воспроизведенных препаратов, в том числе отечественных, стоимость которых существенно ниже.</p><p>Целью данного исследования явилась оценка отношения российских пациентов к воспроизведенным препаратам, изменяющим течение РС (ПИТРС), особенностей формирования отношения к замене с оригинального на воспроизведенный препарат.</p><sec><title>Пациенты и методы</title><p>Пациенты и методы. Опрошено 300 пациентов из шести регионов Российской Федерации, имеющих опыт перехода с оригинального препарата на отечественный биоаналог или дженерик не ранее 2009 г., принимающих препараты интерферон бета-1а 44 мкг, интерферон бета-1b, глатирамера ацетат и терифлуномид.</p></sec><sec><title>Результаты и обсуждение</title><p>Результаты и обсуждение. Большинство пациентов (63%) не замечают никаких изменений при замене препарата с оригинального на воспроизведенный, часть (28%) испытывают ухудшение самочувствия, часть (7%) – улучшение состояния. Молодые пациенты (до 30 лет) сравнительно реже отмечают ухудшение самочувствия при замене препарата. Ухудшение состояния на фоне замены препарата значительно чаще испытывают те пациенты, кому эта замена была осуществлена в аптеке (74% случаев), а не лечащим врачом (только 54% случаев ухудшения). Большинство (87%) пациентов с ремиттирующим РС (РРС) не прекращали прием препарата после замены; о прекращении приема препарата сообщили 13% опрошенных. Среди них преобладают те, кому замену осуществили в аптеке, а не по рекомендации врача (более 80% таких случаев). Побочные реакции на новый препарат – другая причина отказа от препарата (20% от всех случаев отказа). У пациентов, получающих интерферон бета-1b, на порядок выше негативное отношение к отечественным ПИТРС: 52% опрошенных дали им отрицательную оценку (по сравнению с 20–35% в других группах). Сравнительно выше лояльность к российским ПИТРС у пациентов, принимающих интерферон бета-1а (20% негативных оценок в этой группе – заметно меньше, чем в других) и терифлуномид (здесь сравнительно выше доля положительных оценок российских препаратов – 25% по сравнению с 11–16% в других группах). Большинство (76%) опрошенных отметили, что им интересно узнавать о разработке и регистрации новых российских препаратов.</p></sec><sec><title>Заключение</title><p>Заключение. Большинство пациентов с РРС не склонны негативно относиться к российским ПИТРС. Удельный вес оценок в пользу российских ПИТРС превышает вес оценок против них. Основная работа при формировании лояльности к российским ПИТРС должна проводиться в области изменения представлений о побочных реакциях. Это позволит существенно повысить приверженность терапии и качество оказываемого лечения.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>рассеянный склероз</kwd><kwd>интерфероны бета</kwd><kwd>глатирамера ацетат</kwd><kwd>терифлуномид</kwd><kwd>воспроизведенные препараты</kwd><kwd>биоаналоги</kwd></kwd-group><kwd-group xml:lang="en"><kwd>multiple sclerosis</kwd><kwd>interferons beta</kwd><kwd>glatiramer acetate</kwd><kwd>teriflunomide</kwd><kwd>reproduced drugs</kwd><kwd>biosimilars</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Исследование спонсировалось ЗАО «БИОКАД».</funding-statement></funding-group><funding-group xml:lang="en"><funding-statement>The paper has been sponsored by BIOCAD.</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">Hauser SL, Cree BAC.
