Chronic myeloid leukemia (CML) is a myeloproliferative neoplasm characterized by a chromosomal translocation that results in the generation of the BCR-ABL1 oncogene, which encodes the chimeric BCR-ABL1 protein with tyrosine kinase activity. Allosteric tyrosine kinase inhibitors (TKIs) represent an improvement of 2-fold in efficacy over standard inhibitors and are better tolerated.
