Ponatinib in treatment of chronic myeloid leukemia with T315I mutation

Abstract

Chronic myeloid leukemia (CML) is a type of myeloproliferative neoplasm associated with a characteristic chromosomal translocation t(9;22)(q34;q11) which causes the formation of the Philadelphia chromosome (Ph). Therapeutic progress made in the last two decades and new-generation tyrosine kinase inhibitors (TKIs) introduction, signifi cantly increased patients’ prognosis. We present a case study of a Ph-positive CML patient with a point BCR/ABL1 mutation T315I treated with ponatinib.
