Nilotinib (Tasigna((R))) is a more potent BCR-ABL inhibitor than imatinib and was designed to overcome imatinib's deficiencies. Nilotinib has significant efficacy in patients with chronic myeloid leukemia (CML) in chronic phase, accelerated phase and blastic phase, following imatinib failure. Based on the results of the Evaluating Nilotinib Efficacy and Safety in Clinical Trials-Newly Diagnosed Patients (ENESTnd) study, the US FDA has granted accelerated approval of nilotinib for the treatment of adult patients with newly diagnosed Philadelphia chromosome-positive CML in chronic phase. Imatinib has changed our perceptions of the therapeutic power of targeted inhibition of a pathologically active kinase. Nilotinib, a designer agent built on the imatinib scaffold, has proven superior to its template agent by every significant surrogate marker we use in monitoring CML. Nilotinib's clinical superiority over imatinib, as demonstrated by the ENESTnd study, has established it as an agent that we believe is a significant further step towards the cure of CML.
