Dexrazoxane was designated by the US FDA as an orphan drug for "prevention of cardiomyopathy for children and adults 0 through 16 years of age treated with anthracyclines". This decision allows virtually all children to receive dexrazoxane starting with the first dose of anthracycline at the discretion of the treating provider. The label change by the agency announcing dexrazoxane as an approved cardio-oncology protectant has been followed by a review by the agency. Currently, the only FDA and EMA approved cardioprotective treatment for anthracycline cardioprotection is dexrazoxane, which provides effective primary cardioprotection against anthracycline-induced cardiotoxicity without reducing anthracycline activity and without enhancing secondary malignancies.
