This study will test the safety and efficacy of an infusion of a baby's own (autologous) umbilical cord blood as compared with placebo in babies born with history and signs of hypoxic-ischemic brain injury.
The purpose of this phase II study is to assess the safety and efficacy of up to two intravenous infusions of autologous volume and red blood cell reduced nucleated umbilical cord blood cells as compared with placebo in neonates with neonatal encephalopathy undergoing hypothermia treatment. Efficacy will be estimated by one year survival and score on Bayley III scores in all three domains equal to or greater than 85. This will be a randomized, double-blind, placebo controlled multi-site trial of up to 160 infants who qualify for cooling.

Biological Infusion of autologous cord blood

Infants who meet study enrollment criteria will receive up to 2 infusions of their own volume reduced cord blood cells. The number of doses will be determined by the amount of available cord blood cells.

Biological Placebo

Infants who meet study enrollment criteria will receive up to 2 placebo infusions composed of an equivalent volume (volume of product that would have been administered if the infant randomized to the intervention arm) of packed red blood cells (PRBCs) from the red cell compartment of the separated cord blood unit.

Intervention cell recipients Experimental

Experimental: infusions: infants with moderate to severe hypoxic ischemic encephalopathy, begin cooling, and have autologous nucleated cord blood cells available for infusion will receive up to two infusions. Outcomes will be measured at 22-26 months by neurodevelopment assessment

Placebo recipients Placebo Comparator

Control: infants with moderate to severe hypoxic ischemic encephalopathy, begin cooling, and have cord blood available for infusion will receive placebo (a mix of autologous cord blood red blood cells and plasma) infusions. Outcomes will be measured at 22-26 months by neurodevelopment assessment

Criteria

Inclusion Criteria:

NICHD Neonatal Research Network Hypothermia Trial inclusion criteria
Mothers must have consented or given verbal assent for cord blood collection at delivery, and cord blood must be available for volume and red blood cell reduction before 45 hours of age
The infant must be able to receive at least one dose of autologous cord blood before 48 hours of age
All infants must have signs of encephalopathy within 6 hours of age

Exclusion Criteria:

Major congenital or chromosomal abnormalities
Severe growth restriction (birth weight <1800 g)
Opinion by attending neonatologist that the study may interfere with treatment or safety of subject
Moribund neonates for whom no further treatment is planned
Infants born to mothers are known to be HIV, Hepatitis B, Hepatitis C or who have active syphilis or CMV infection in pregnancy
Infants suspected of overwhelming sepsis
ECMO initiated or likely in the first 48 hours of life

The Bayley is a standardized, norm-referenced measure that assesses development in Cognitive, Language and Motor domains. Composite standard scores can be derived that have a mean of 100 and a standard deviation of 15.
