First causal treatment option for Friedreich's Ataxia via Erythropoietin (EPO)

Technology collaboration OFFER
Abstract
An Austrian university offers the first treatment option for Friedreich´s Ataxia (FRDA), an inherited neurodegenerative disease. It causally targets FRDA
using Erythropoietin (EPO) to increase the level of Frataxin, decreased levels of which are reportedly responsible for the development of FRDA. So far
no other effective treatment is available which is at an advanced development stage. Industrial partners for further developing & commercialising
EPO for the treatment of FRDA are sought.

ArmaGen® Re-engineers Erythropoietin For Brain Penetration

Medical News Today, Article Date: 17 Jul 2010

"EPO drug development for the brain is limited, because EPO does not cross the blood-brain barrier (BBB)"

"EPO-driven neuroprotection in human brain disorders is now possible with systemic administration of the HIRMAb-EPO fusion protein at doses that have minimal effects on erythropoiesis."
