Erythropoietin for the Repair of Cerebral Injury in Very Preterm Infants

Phase 3

• Conditions: Intraventricular Hemorrhage of Prematurity
• Interventions: Drug: recombinant human Erythropoietin; Drug: Placebo

• Registration Number: NCT02076373
• Lead Sponsor: University of Zurich

Brief Summary

The purpose of this randomized and placebo-controlled EpoRepair trial is to evaluate the effect of intravenously administered recombinant human erythropoietin (Epo) as compared to placebo in preterm infants with brain damage on neurological development until five years od age.

Detailed Description

Worldwide, 1% of all infants are born very preterm with less than 32 weeks of gestation, which is more than 2 months before expected date of delivery. If these smallest infants suffer in addition to prematurity a second hit, such as intraventricular hemorrhage or parenchymal infarction, they are at high risk for learning disabilities, mental retardation, and cerebral palsy in later life.

Intraventricular hemorrhage and parenchymal infarction occur in about 12% of very preterm infants, mostly in the very smallest and within the first few days after birth, and can be recorded by cranial ultrasound. Except for shunt insertion to divert cerebrospinal fluid in infants with posthemorrhagic hydrocephalus and possibly the removal of blood clots, there is no treatment for established intracerebral bleeding, and no medical therapies exist to ameliorate the neurodevelopmental sequelae.

Apart from stimulating production of red blood cells in the bone marrow, recombinant human erythropoietin (Epo) has been shown to exert neuroprotective action in a variety of animal models and in clinical studies. Epo administration has been found to be beneficial and safe in randomized controlled trials (RCT) involving adult and infant patients.

Observational data suggest that Epo administered to very preterm infants in order to prevent from anemia improves long-term cognitive outcomes until school-age especially in those infants who had suffered intracerebral bleeding. These data, however, are observational and therefore do not allow for any firm conclusions or recommendations. The hypothesis generated by these data calls for confirmation or refutation by an RCT designed to address this question.

Arm && Interventions

Group	Intervention	Description
recombinant human Erythropoietin (Epo)	recombinant human Erythropoietin	Epo 2000 U in normal saline per ml/kg of body weight 5 times intravenously, total dosage 10000 U per 5ml/kg. In detail: For loading 3 times beginning at day 5 of life (± 2 days), followed at 24 hours and 48 hours later. For maintenance 2 times, at day 10 and day 17 after the first study medication.
Control	Placebo	Placebo 1 ml normal saline/kg of body weight 5 times intravenously, total dosage 5 ml/kg. In detail: For loading 3 times beginning at day 5 of life (± 2 days), followed at 24 hours and 48 hours later. For maintenance 2 times, at day 10 and day 17 after the first study medication.

Primary Outcome Measures

Name	Time	Method
Neurodevelopmental outcome	5 years	With 5 years of age, composite intelligence quotient to be assessed by standardized IQ tests.

Secondary Outcome Measures

Name	Time	Method
Biomarker serial cranial ultrasound	Infants will be followed for the duration of hospital stay, an expected average of 14 weeks	Cranial ultrasound is a useful point of care method to detect, confirm and monitor brain damage including intracerebral bleeding. It is part of clinical routine for the duration of hospital stay.
Safety	Infants will be followed for the duration of hospital stay, an expected average of 14 weeks	Analysis will be performed to get insight about the distributions of adverse events and other safety relevant outcomes between groups.
Overall developmental outcome	5 years	Neurological and formal psychological examination. Normal Overall developmental outcome is classified as normal if IQ \>84 and without one or more of the following: motor impairment, cognitive impairment, behavior problems, poor general health, severe hearing loss, or bilateral blindness.
Biomarker cranial MRI	40 weeks postmenstrual age	Brain injury score assessed on cranial MRI, including brain maturation score and white matter and gray matter injury scores, as biomarker for long-term neurodevelopmental outcome.
Neurodevelopmental outcome	2 years	Bayley Scales of Infant Development (BSID-III) and the presence or absence of impairment of motor function (cerebral palsy) and neurosensory function (blindness or deafness) will be assessed with 18 to 24 months.
