 Friedreich ataxia FRDA is an inherited recessive disorder characterized by progressive neurological disability. FRDA is the consequence of frataxin deficiency. Although several drugs have been proposed for FRDA, there is no available treatment. Recently it was shown that recombinant human erythropoietin rhu-EPO administration increases frataxin expression in cultured human lymphocytes of FRDA patients. It is therefore of primary importance to test extensively rhu-EPOs ability in increasing frataxin levels in-vitro and in-vivo. In addition rhu-EPO is an already available and commercialized drug approved for the treatment of anaemia associated with chronic renal disease, heart failure and cancer. Towards this overall purpose, we will perform an acute clinical trial in FRDA patients with rhu-EPO and will assess its effect in-vivo on frataxin expression. In addition, rhu-EPOs safety in FRDA patients based on laboratory parameters and neurological indexes will be tested. The results will be useful to gain new insight in the role of rhu-EPO in FRDA, and in the future, it may be useful to plan further clinical trials.
