Safety Study of Erythropoietin (EPO) in Parkinson's Disease

The purpose of this study is to determine whether recombinant human Erythropoietin (EPOrh) is safe in the treatment of patients with Parkinson's Disease.

After onset of Parkinson's Disease (PD)- in spite of the use of medications that constitute the symptomatic treatment- the disease is worsens with an inevitable progression, thus causing complications that lead to the loss of patient´s manual skills and independent gait. At present, the treatment of PD with the use of medications is based on dopamine precursors and dopaminergic agonists but as the disease advances, other symptoms that do not respond to dopaminergic stimulation do appear. For this reason, it is a priority to find a way to focus on neuroprotection during the course of the disease. There are evidences of neuroprotecting therapeutic alternatives in such substances as erythropoietin (EPO). Positive results on the neuroprotective/neurotrophic efficacy of EPO in neurological and psychiatric diseases have been obtained from treatment trials, but nevertheless, it is indispensable demonstrate that with the proposed medication doses it's well tolerated by PD patients.
