За последнее десятилетие мы наблюдаем значимое изменение в современных подходах в 1-й линии терапии хронического лимфоцитарного лейкоза (ХЛЛ). Результаты исследования СLL10 определили режим FCR как терапию выбора у молодых пациентов, без значимой сопутствующей патологии, в то время как для пациентов старше 65 лет чаще рассматривается режим BR как менее токсичный. По опубликованным данным, у 46% пациентов с впервые диагностированным ХЛЛ выявляется сопутствующая патология. Кроме того, пациенты из группы высокого риска [с del(17p) и/или мутацией TP53] чаще всего не отвечают на иммунохимиотерапию (ИХТ). Таким образом, около 1/2 пациентов не могут быть пролечены или не ответят на терапию стандартными схемами ИХТ. Таргетная терапия ингибиторами тирозинкиназы Брутона (ТКБ) занимает важное место в лечении пациентов с ХЛЛ в 1-й линии. Акалабрутиниб – высокоселективный ингибитор ТКБ II поколения, который не ингибирует мишени EGFR, ITK или TEC. Акалабрутиниб в комбинации с обинутузумабом или в монотерапии может рассматриваться как высокоэффективная и безопасная опция 1-й линии терапии ХЛЛ. Учитывая высокую селективность препарата, акалабрутиниб может рассматриваться как предпочтительная опция для пациентов, не подходящих для ИХТ, в том числе коморбидных пациентов с сердечно-сосудистыми заболеваниями или наличием факторов риска для их развития. Ключевые слова: хронический лимфоцитарный лейкоз, ингибиторы тирозинкиназы Брутона, иммунохимиотерапия, таргетная терапия, акалабрутиниб.

Over the past decade, we have seen a significant change in modern approaches in the first-line treatment of chronic lymphocytic leukemia (CLL). The CLL-10 study data established the FCR regimen as the treatment of choice for younger patients with limited comorbidities, while for patients older than 65 years, the BR regimen is more often considered as less toxic one. According to published data, 46% of patients with newly diagnosed CLL have comorbidities. Moreover, high-risk patients with del(17p) and/or TP53 mutation do not have response on immunochemotherapy (ICT) most often. Thus, about 1/2 of the patients cannot be treated or will not respond to standard ICT regimens. Targeted therapy with Bruton's tyrosine kinase (BTK) inhibitors is an important option of the first-line treatment of patients with CLL. Acalabrutinib is a highly selective second-generation BTK inhibitor that does not inhibit EGFR, ITK or TEC targets. Acalabrutinib in combination with obinutuzumab or as monotherapy can be considered as a highly effective and safe option of the first line of CLL therapy. Based on the hight selectivity of the agent, acalabrutinib can be considered as the preferable option for patients who are not eligible for ICT, including patients with commodities, such as cardiovascular diseases or risk factors for their development. Key words: chronic lymphocytic leukemia, Bruton’s tyrosine kinase inhibitors, immunochemotherapy, targeted therapy, acalabrutinib.
