The role of second generation Bruton tyrosine kinase inhibitors in the treatment of chronic lymphocytic leukemia. Resolution

Chronic lymphocytic leukemia (CLL) is the most common type of adult leukemia, with incidence rate of 4: 100 thousand per year, according to European data. CLL remains an incurable disease, with most patients over 60 years old. Immunochemotherapy schemes today remain the standard treatment approach for CLL. The advent of novel molecules expands possibilities of treating this disease. Targeted therapy with small molecule inhibitors of Bruton tyrosine kinase (BTK) occupies an important place in the treatment of patients with CLL, both for first-line therapy and for treatment of relapses. The drug acalabrutinib as a highly selective new generation of BTK inhibitor can be considered as an efficient and safe option for first-line therapy and for treatment of the disease relapse in patients with CLL, especially in patients with comorbidity, including cardiovascular diseases (CDV) or risk factors for CVD.
