Overview

CPX-351 (Vyxeos) is a liposomal formulation containing a fixed 5:1 molar ratio of cytarabine and daunorubicin. Developed by Celator Pharmaceuticals (later acquired by Jazz Pharmaceuticals), it is specifically indicated for the treatment of adults and pediatric patients (1 year and older) with newly-diagnosed therapy-related acute myeloid leukemia (t-AML) or AML with myelodysplasia-related changes (AML-MRC). The liposomal delivery system maintains the synergistic ratio of the two drugs in the plasma and preferentially delivers them to the bone marrow, where they are taken up by leukemia cells. Cytarabine acts as a nucleoside metabolic inhibitor that interferes with DNA synthesis, while daunorubicin acts as an anthracycline that intercalates DNA and inhibits topoisomerase II.
