Clofarabine (Clolar) is an infusion for children and young adults whose acute lymphoblastic leukaemia has come back after at least two other treatments.
Clofarabine is a second-generation purine nucleoside analogue combining features of fludarabine and cladribine. The FDA granted accelerated approval in December 2004 for patients aged 1 to 21 with relapsed or refractory acute lymphoblastic leukaemia after at least two prior regimens, based on a single-arm study in which about 20% of heavily pretreated children achieved complete remission; the EU authorised Evoltra in 2006 for the same paediatric population. It is now used mainly as a bridge to transplant and in combination regimens for relapsed ALL, and off label in adult AML. Capillary leak and systemic inflammatory response syndrome, hepatotoxicity and prolonged cytopenias are the key risks.
Phosphorylated by deoxycytidine kinase to clofarabine triphosphate, which inhibits ribonucleotide reductase and DNA polymerase and disrupts mitochondrial membranes, triggering apoptosis.
