Leukemia and Clofarabine

Available by prescription only, clofarabine (Clolar^®) is a chemotherapy medication that is reserved for use in children and young adults who have a type of blood and bone marrow cancer called acute lymphoblastic leukemia (ALL). Clofarabine comes in the form of an injection that is given into a vein (an intravenous, or IV, infusion) daily for five days every two to six weeks.

Specifically, clofarabine is approved for use in those who have not responded adequately to at least two other treatment regimens. It is approved for use in children age 1 to 21 years old. The medicine works by interfering with cell division, which helps prevent cancer cells from growing and multiplying.
