Nilotinib in the treatment of chronic myeloid leukemia.

Abstract

Nilotinib, a second-generation tyrosine kinase inhibitor, was designed to overcome resistance of a wide range of BCR-ABL mutants to imatinib. When used in the first-line treatment in newly diagnosed chronic myeloid leukemia (CML), it induces faster and deeper molecular responses in higher than imatinib percentage of patients. Treatment-free remission after achievement of sustained deep molecular response represents an emerging treatment goal for a proportion of patients with CML in chronic phase. The pharmacologic properties, and the role of nilotinib in the current treatment of CML in the context of considered optimal end point of therapy including the discontinuation trial and durable treatment-free remission achievement is discussed in the article.
