Jeffrey Lancet, MD, Moffitt Cancer Center, Tampa, FL, discusses the analysis of genetic characteristics and outcomes by mutation status in the phase 3 study of CPX-351 (liposomal daunorubicin and cytarabine for injection) vs 7+3 chemotherapy in newly diagnosed high-risk or secondary acute myeloid leukemia (AML). TP53 mutations were associated with a poor prognosis, irrespective of treatment arm, whereas median overall survival was longer with CPX-351 compared with 7+3 among patients with two of the most common mutations, DNMT3A and TET2. This interview took place at the American Society of Hematology (ASH) 2019 Annual Meeting and Exposition in Orlando, FL.
