Only direct medical costs per patient (drug therapy costs) were taken into account in the model.</p> <p><bold>Results. </bold>As a result of CEA, it was shown that the mean number of progression-free years lived during the 20-year modeling period in CLL when using ibrutinib in combination with venetoclax was 12.63 years, which was 8.16 years more than the mean number of progression-free years in case of use of FCR – 4.47 years. The median number of years lived during a 20-year modeling period in CLL using ibrutinib in combination with venetoclax would be 18.12 years, which is 3.7 years more than the average number of years that one patient lives if he receives FCR – 14.41 years. Compared to the FCR therapy regimen included in the high-cost nosology (HCN) program, already at the 7-year horizon, the cost of the ibrutinib + venetoclax regimen for the healthcare system becomes lower than the cost of FCR due to a fixed duration with superior efficacy rates and allows to increase life expectancy without progression in adult patients with CLL, the cost of an additional year of life without progression is 2,770,241.80 rubles/year. The method is dominant from an economic point of view, because the cost-effectiveness ratio in terms of progression-free life year for ibrutinib with venetoclax is 7,341,534,177 lower than for FCR. Compared to other targeted therapy drugs for CLL, the burden on the healthcare budget can be reduced to 26.4%, or by 7,342 million rubles, when using ibrutinib + venetoclax. for 5 years of therapy.</p> <p><bold>Conclusion.</bold> Ibrutinib + venetoclax is the dominant method due to the lower cost with greater efficiency compared to the current option of therapy within the framework of the HCN and other targeted CLL therapy options.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Цель исследования: </bold>проведение оценки экономических последствий (клинико-экономический анализ [КЭА] и анализ влияния на бюджет) при комбинированной таргетной терапии ибрутиниб+венетоклакс для терапии взрослых пациентов с хроническим лимфолейкозом (ХЛЛ) высокого риска в рамках льготного лекарственного обеспечения.</p> <p><bold>Методы. </bold>Построена аналитическая модель принятия решений в MS Excel, которая позволяет проводить КЭА при применении комбинации ибрутиниб+венетоклакс фиксированной продолжительности по сравнению с применением FCR (флударабин, циклофосфамид и ритуксимаб) и анализ влияния на бюджет при применении комбинации ибрутиниб+венетоклакс фиксированной продолжительности по сравнению с таргетной терапией (акалабрутиниб, ибрутиниб, комбинация венетоклакс+ обинутузумаб) в терапии первой линии пациентов с ХЛЛ высокого риска. В модели были учтены только прямые медицинские затраты на одного пациента (затраты на лекарственную терапию).</p> <p><bold>Результаты.</bold> В результате КЭА показано, что среднее число прожитых лет без прогрессирования в течение 20-летнего периода моделирования при ХЛЛ при использовании ибрутиниба в комбинации с венетоклаксом составит 12,63 года, что на 8,16 года больше, чем среднее число лет без прогрессирования, которые проживет один пациент, если он будет получать FCR, – 4,47 года. Среднее число прожитых лет в течение 20-летнего периода моделирования при ХЛЛ при использовании ибрутиниба в комбинации с венетоклаксом составит 18,12 года, что на 3,7 года больше, чем среднее число лет, которые проживет один пациент, если он будет получать FCR, – 14,41 года. По сравнению с включенным в программу высокозатратных нозологий (ВЗН) режимом терапии (FCR) уже на 7-летнем горизонте стоимость схемы ибрутиниб+венетоклакс для системы здравоохранения становится ниже стоимости FCR за счет фиксированной длительности при превосходящих показателях эффективности и позволяет увеличивать продолжительность жизни без прогрессирования взрослых больных ХЛЛ, стоимость дополнительного года жизни без прогрессирования составляет 2 770 241,80 руб/год. Метод является доминантным с экономической точки зрения, т.к. коэффициент «затраты–эффективность» по показателю «год жизни без прогрессирования» для ибрутиниба с венетоклаксом на 7 341 534 177 ниже, чем для FCR. По сравнению с другими препаратами таргетной терапии ХЛЛ нагрузку на бюджет системы здравоохранения при использовании ибрутиниб+венетоклакс удастся снизить до 26,4%, или на 7 342 млн руб., за 5 лет терапии.</p> <p><bold>Заключение.</bold> Ибрутиниб+венетоклакс является доминантным методом, т.к. при большей эффективности обладает меньшей стоимостью по сравнению с текущей опцией терапии в рамках ВЗН и с другими таргетными опциями терапии ХЛЛ.</p></trans-abstract><kwd-group xml:lang="en"><kwd>chronic lymphocytic leukemia</kwd><kwd>ibrutinib + venetoclax</kwd><kwd>ibrutinib</kwd><kwd>acalabrutinib</kwd><kwd>ibrutinib</kwd><kwd>venetoclax</kwd><kwd>cost minimization analysis</kwd><kwd>budget impact analysis</kwd><kwd>pharmacoeconomics</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>хронический лимфолейкоз</kwd><kwd>ибрутиниб+венетоклакс</kwd><kwd>ибрутиниб</kwd><kwd>акалабрутиниб</kwd><kwd>ибрутиниб</kwd><kwd>венетоклакс</kwd><kwd>анализ минимизации затрат</kwd><kwd>анализ влияния на бюджет</kwd><kwd>фармакоэкономика</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Kipps T.J., Stevenson F.K., Wu C.J., et al.
