It develops through a multistage process of a series of genomic events. Bruton’s tyrosine kinase (BTK) plays an important role in signal transduction through constantly active BCR pathway. It participates in all aspects of B cell development including proliferation, maturation, differentiation, and apoptosis. Therefore, it seems reasonable to modulate BTK using pharmaceutical agents with the goal to suppress tumor process. The effect of 1st generation BTK inhibitor ibrutinib on non-target kinases is significant and causes some adverse events which can limit its use in older patients with concomitant pathologies. The results of completed trails have convincingly shown safety advantage and similar effectiveness of highly selective 2nd generation BTK inhibitor acalabrutinib compared to ibrutinib in all subgroups of patients with CLL. Considering the necessity of long term BTK inhibitor therapy (until progression or unacceptable progression), long-term manageable safety profile of acalabrutinib is important. The article discusses clinical pharmacology, effectiveness and safety of acalabrutinib therapy in the context of clinical trials. Analysis of medical histories of patients with CLL treated at the Clinical and Diagnostic Center of the Lapino Clinical Hospital, “Mother and Child” group of companies, in the last year was performed, and indications for treatment using 2nd generation BTK inhibitor were evaluated.</p></abstract><trans-abstract xml:lang="ru"><p>   Хронический лимфолейкоз (ХЛЛ) – В-клеточная опухоль из малых лимфоцитов, в основе молекулярного патогенеза которой лежит многоступенчатый процесс в виде серии геномных событий. Важную роль в передаче сигнала через постоянно активный BCR-путь играет нерецепторная тирозинкиназа Брутона (Bruton’s tyrosine kinase, BTK), участвующая во всех аспектах развития В-клеток, включая пролиферацию, созревание, дифференцировку и апоптоз. В связи с этим представляется оправданным фармакологическое воздействие на BTK с целью подавления активности при развитии опухолевого процесса. Несомненное значение имеет влияние ингибитора BTK 1-го поколения ибрутиниба на нецелевые киназы, обусловливающее ряд нежелательных явлений, развитие которых в популяции больных пожилого возраста с сопутствующей патологией может ограничивать его дальнейшее применение. Результаты проведенных к настоящему времени исследований убедительно продемонстрировали преимущество в этой ситуации высокоселективного ингибитора BTK 2-го поколения акалабрутиниба перед ибрутинибом во всех подгруппах больных ХЛЛ наряду с сопоставимой эффективностью. С учетом необходимости в длительной терапии ингибиторами BTK (до прогрессирования или развития неприемлемой токсичности) большое значение имеет долгосрочный управляемый профиль безопасности акалабрутиниба. В статье освещены вопросы клинической фармакологии, дана оценка эффективности и безопасности терапии акалабрутинибом на основании результатов проведенных клинических исследований. Выполнен анализ историй болезни пациентов с ХЛЛ, обратившихся в поликлиническое отделение лечебно-диагностического центра Клинического госпиталя «Лапино» группы компаний «Мать и дитя» за прошедший год, и оценены показания к лечению ингибитором ВТК 2-го поколения.</p></trans-abstract><kwd-group xml:lang="en"><kwd>chronic lymphocytic leukemia</kwd><kwd>acalabrutinib</kwd><kwd>2<sup>nd</sup> generation Bruton’s tyrosine kinase inhibitor</kwd><kwd>effectiveness</kwd><kwd>manageable safety profile</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>хронический лимфолейкоз</kwd><kwd>акалабрутиниб</kwd><kwd>ингибитор тирозинкиназы Брутона 2-го поколения</kwd><kwd>эффективность</kwd><kwd>управляемый профиль безопасности</kwd></kwd-group><funding-group><funding-statement xml:lang="en">The work was performed without external funding</funding-statement><funding-statement xml:lang="ru">Работа выполнена без спонсорской поддержки</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Moia R., Patriarca A., Schipani M. et al.
