Rates of Myeloid Neoplasms in Patients With Unexplained Cytopenias 5.5” .25” G:.5” Patients with unexplained cytopenias may never receive a definitive diagnosis, or may eventually be classified as having myelodysplastic syndromes (MDS, a myelo- proliferative neoplasm [MPN] or, if their cytopenias persist, as having idiopathic cytopenia of undetermined significance [ICUS]). Adding mutational profiling to the evaluation of patients with unexplained cytopenias could help identify individuals who have or are at risk of developing a myeloid malignancy, according to results of a prospective cohort study published in Blood. Lead author Luca Malcovati, MD, from the Department of Molecular Medicine at the University of Pavia in Italy, and colleagues looked for somatic mu- tations in 40 genes known to be recurrently mutated S:6.75” in myeloid malignancies to determine their predic- tive value for identifying patients with, or at high risk of developing, a myeloid neoplasm. The researchers found that carrying one or more of these somatic mutations was associated with a high probability of de- veloping a myeloid neoplasm during follow-up (hazard ratio [HR] = 13.9; p<0.001). “Mutation profiling on peripheral blood cells has a high predictive value for identifying individuals at high risk of developing MPNs,” Dr. Malcovati told ASH Clinical News. “Mutation analyses may be a valuable complement BOSULIF offers proven efficacy for patients with resistance or intolerance to prior therapy 2 In 2nd-line treatment, after imatinib (n=266 evaluable) a 34 % of patients 53 % of patients achieved MCyR at 6 months achieved MCyR with a minimum follow-up of 23 months (95% CI: 28.2, 39.9) Median duration of MCyR was not reached at the time of analysis 53% of patients with MCyR maintained MCyR for at least 18 months (with a minimum follow-up of 23 months) In 3rd-line treatment, after imatinib followed by nilotinib and/or dasatinib therapy (n=108 evaluable) • 27% of patients achieved MCyR by 6 months (95% CI: 18.8, 36.2) • 32% of patients achieved MCyR with a minimum follow-up of 13 months • Median duration of MCyR was not reached at the time of analysis — 51% of patients with MCyR maintained MCyR for at least 9 months (with a minimum follow-up of 13 months) BOSULIF has a distinct safety and tolerability profile 2 Warnings and precautions include: gastrointestinal toxicity, myelosuppression, hepatic toxicity, fluid retention, renal toxicity, and embryofetal toxicity.

Women of childbearing potential should be advised of potential hazard to the fetus and to avoid becoming pregnant while receiving BOSULIF. Adverse Reactions: The most common adverse reactions observed in greater than 20% of patients in the Phase 1/2 safety population (N=546) were diarrhea, nausea, thrombocytopenia, vomiting, abdominal pain, rash, anemia, pyrexia, and fatigue.
