Maintaining treatment with imatinib as initial therapy in patients with chronic myeloid leukemia (CML) may yield positive outcomes, including increased overall survival to ≥5 years, according to a study published in the New England Journal of Medicine (NEJM). The follow-up study of the International Randomized Study of Interferon and ST1571 (IRIS), a multicenter, international, randomized, phase 3 trial, included patients aged 18 to 70 years diagnosed with Ph-positive CML in chronic phase within 6 months before the start of the study.
