Elacytarabine (CP-4055 or araC-5'elaidic acid ester) is a lipid-conjugated derivative of the nucleoside analog cytarabine. Elacytarabine blocks cell division and may kill cancer cells. It is a type of antimetabolite. It was studied in clinical trials for the treatment of solid tumors. In preclinical and clinical studies, elacytarabine has demonstrated both safety and efficacy in acute myeloid leukemia (AML), with noteworthy activity among the cytarabine-refractory AML population. Elacytarabine was granted orphan drug designation status from the European Commission in 2007 and from the US FDA in 2008, with a fast-track approval designation from the FDA in 2010. Elacytarabine development has been discontinued.
