SAN DIEGO – Induction therapy with the investigational drug CPX-351 (Vyxeos), a liposomal formulation of cytarabine and daunorubicin, allowed more older patients with newly diagnosed secondary AML to bridge successfully to transplant than did standard 7+3 cytarabine and daunorubicin, based on data reported by Jeffrey E. Lancet, MD, at the annual meeting of the American Society of Hematology.
The data come from a subgroup analysis of a phase III study in 60- to 75-year-old patients with secondary AML. Initial survival data from that randomized open-label study, reported last June at the annual meeting of the American Society of Clinical Oncology, indicated CPX-351 significantly improved overall survival, event-free survival, and treatment response without an increase in 60-day mortality or in the frequency and severity of adverse events, compared with the standard 7+3 regimen of cytarabine and daunorubicin.
Dr. Lancet of the H. Lee Moffitt Cancer Center and Research Institute, Tampa, Fla., credited the better results to the higher level of complete responses and complete responses with incomplete platelet or neutrophil recovery with the liposomal formulation.
In a video interview, Dr. Lancet discussed how better disease control allowed more patients to be transplanted and next steps for expanded study in this patient population as well as in younger patients with AML.
