Nilotinib therapy after resistance to imatinib

Abstract

In this article we present the case of a 43-year-old man with chronic myeloid leukemia (CML) successfully treated with nilotinib. At presentation we started him on imatinib at standard dose of 400 mg/day but after 36 months of treatment the patient didn’t achieve a molecular response. We switched him on second-generation tyrosine kinase inhibitor (TKI), nilotinib, at the dose of 800 mg/day. After twelve months on nilotinib the patient obtained a complete molecular response. During treatment with nilotinib we did not observe any drug-related toxicity.
