A phase I clinical trial reveals nilotinib has a relatively favorable safety profile and demonstrates activity against drug-resistant CML, with notable improvements in chronic phase CML patients. However, the agent shows less activity in acute lymphoblastic leukemia patients and may require careful monitoring for cardiac events.
