Abstract

Introduction: Treatment options in myelodysplastic syndromes (MDS) remain limited. The introduction of novel therapies that can improve response rates and survival outcomes in MDS remains a challenge. Clofarabine is a purine nucleoside analog that works primarily via inhibition of DNA biosynthesis and the ribonucleotide reductase enzyme with recent evidence suggesting that at low doses it may affect DNA methylation. It has been successfully used in the treatment of acute myeloid leukemia (AML) and is under investigation in MDS. Areas covered: A PubMed search for articles pertaining to clofarabine was conducted and streamlined to only include data on MDS or AML that evolved from MDS. Also included were clofarabine-related response and safety data from presentations at the 52(nd) Annual American Society of Hematology Meeting in Orlando, Florida, USA. Expert opinion: Clinical trials using clofarabine in MDS and MDS/myeloproliferative neoplasms have produced overall response rates of 31 - 43% including complete responders. Although myelosuppression is an important side effect, clofarabine is generally well tolerated in MDS. Clofarabine is currently available in an intravenous form with an oral formulation presently under investigation, either as a single agent or in combination therapy in MDS. Larger studies may help clarify the viability of clofarabine in the treatment of MDS patients.
