DescriptionClofarabine is a purine nucleoside antimetabolite that is being studied in the treatment of cancer. It is marketed as Clolar in the U.S. and Canada, or Evoltra in Europe, Australia, and New Zealand. Clofarabine is used in paediatrics to treat a type of leukaemia called relapsed or refractory acute lymphoblastic leukaemia (ALL), only after at least two other types of treatment have failed. It is not known if the drug extends life expectancy. Its potential use in acute myeloid leukaemia (AML) and juvenile myelomonocytic leukaemia (JMML) has been investigated.
