Study summary

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

Read the detailed description

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.

Study arms

  • Experimental
    Erythropoietin

    There are evidences of neuroprotecting therapeutic alternatives in such substances as erythropoietin (EPO) which is a well-known cytokine as a hematopoietic growth factor, so, it is therefore important to control tissular oxygenation. It is considered that EPO protects the neurons by a combination of several mechanisms. EPOrh is used with high effectiveness in the treatment of anemias with deficiency of erythropoietin.

    Drug: Erythropoietin human recombinant (EPOrh)

Interventions

  • DrugErythropoietin human recombinant (EPOrh)

    Administration scheme by subcutaneous via, of an EPOrh solution up to a weekly doses of 60 UI/kg for five weeks

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Oct 1, 2019, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
