Brief Summary:

Hypoxic Ischemic Encephalopathy is also known as 'birth asphyxia related brain injury' and happens when the brain does not receive enough oxygen or blood flow around the time of birth. Birth asphyxia related brain injury is the most common cause of death and neurodisability in term babies.

Cooling therapy has substantially improved the outcomes of babies with HIE. However, unacceptably high rate of adverse outcomes are still seen in cooled babies with HIE.

The EDEN trial is a 3 arm randomised control trial and aims to examine the physiological effects of erythropoietin (Epo) and Darbepoetin alfa (Darbe) therapy on proton magnetic resonance spectroscopy thalamic N-acetylaspartate (NAA) level in babies with neonatal encephalopathy undergoing cooling therapy.

A total of 220 babies with neonatal encephalopathy will be recruited from the participating sites in UK over a 24 month period. The babies will be randomly allocated to erythropoietin, darbepoetin or usual care. MR imaging and spectroscopy will be performed at 1 to 2 weeks of age to examine the brain injury. Neurodevelopmental outcomes will be assessed at 18 months of age.

Primary Outcome Measures :
  1. Primary outcome measure (Mean (SD) of thalamic NAA level) [ Time Frame: Expected average 1 to 2 weeks after birth ]
    Mean (SD) of thalamic NAA level in babies treated with Epo and Darbe when compared with untreated infants.

Secondary Outcome Measures :
