About this study

Official title: Effect of ALlopurinol in Addition to Hypothermia for Hypoxic-ischemic Brain Injury on Neurocognitive Outcome - a Blinded Randomized Placebo-controlled Parallel Group Multicenter Trial for Superiority (Phase III)

Neonatal hypoxic-ischemic encephalopathy (HIE) is a major cause of death or long-term disability in infants born at term in the western world, affecting about 1-4 per 1.000 life births and consequently about 5-20.000 infants per year in Europe.

Hypothermic treatment became the only established therapy to improve outcome after perinatal hypoxic-ischemic insults. Despite hypothermia and neonatal intensive care, 45-50% of affected children die or suffer from long-term neurodevelopmental impairment. Additional neuroprotective interventions, beside hypothermia, are warranted to further improve their outcome.

Allopurinol is a xanthine oxidase inhibitor and reduces the production of oxygen radicals and brain damage in experimental, animal, and early human studies of ischemia and reperfusion.

This project aims to evaluate the efficacy and safety of allopurinol administered immediately after birth to near-term infants with HIE in addition to hypothermic treatment.

Read the detailed description

During labour and childbirth various events (such as placental abruption, uterine rupture, umbilical cord complications etc.) may result in impaired oxygenation and/or perfusion of the newborn brain which may result in brain injury termed "hypoxic-ischemic encephalopathy" (HIE). HIE is associated with development of long-term motor, cognitive, and neurosensory and memory disability and is one of the fundamental problems in perinatal medicine affecting about 5,000-20,000 infants/year in Europe (or 1-4/1000 live births in western societies) and approximately 1 million infants/year worldwide.

In term infants with perinatal asphyxia and postnatal HIE, brain injury predominantly originates in the immediate perinatal period (in contrast to a more distant prenatally acquired brain injury) as indicated by the lack of already established brain injury on early postnatal MRI. Consequently, brain injury in this population may potentially be ameliorated by postnatal pharmacological interventions.

The most common motor disability resulting from HIE is "cerebral palsy", the other major adverse outcome is cognitive disability, which prevents affected patients to lead their lives independently (without assistance and/or financial support).

The single major cause of HIE is a perinatal hypoxic/ischemic event (perinatal asphyxia). This hypoxic insult can cause immediate (necrosis) and delayed death (apoptosis) of (especially neuronal) cells, the latter responsible for a substantial amount of HIE-associated permanent brain damage. Whereas no intervention is known to prevent necrosis, the delayed cell death by apoptosis can be reduced by therapeutic interventions: Apoptosis is in part caused by secondary energy failure which can be reduced by hypothermic treatment.

Apoptosis is also caused by xanthine oxidase-mediated production of cytotoxic oxygen radicals during reperfusion, and there is evidence that allopurinol, a xanthine-oxidase inhibitor, reduces delayed cell death in animal models of perinatal asphyxia and ischemia/reperfusion.

Allopurinol prevents adenosine degradation, oxygen radical formation, preserves NMDA receptor integrity, and consequently may reduce brain injury in HIE by several mechanisms of action which are independent from the proven beneficial effect of hypothermic treatment on cellular energy metabolism. An additional beneficial (or even synergistic?) effect of allopurinol in addition to hypothermia can therefore be expected.

As no safety concerns were known at the start of this study regarding administration of even high doses of Allopurinol to neonates a phase III study was planned instead of a pilot study or an adaptive design. Close follow-up of MR-imaging along with reporting of all safety relevant data to a Data Monitoring Committee (which includes experts for brain imaging not otherwise involved in the study) ensures patients' safety.

Primary objective of this study is to evaluate whether newborns with asphyxia and early clinical signs of hypoxic ischemic encephalopathy will benefit from early administered Allopurinol compared to placebo, both in addition to standard of care, regarding long-term follow-up such as severe neurodevelopmental impairment or death at two years.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • AllopurinolDrug

    Allopurinol, powder for injection (PFI), administered in two doses. First dose (20 mg/kg in 2ml/kg sterile water for injection) given as soon as intravenous access is established and no later than 30min postnatally and second dose (10mg/kg in 1ml/kg sterile water for injection) 12 hours thereafter. The second dose will only be administered to in infants on therapeutic hypothermia. Infants who recover quickly and do not qualify for and hence do not undergo hypothermia will not receive a second dose. Administration will be by continuous infusion using a syringe pump over 10min through secure venous access.

  • MannitolDrug

    Placebo (Mannitol, PFI, 20mg/kg in the same volume and at the same time intervals as the intervention group - (2nd dose 10mg/kg only if infant undergoes therapeutic hypothermia)).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. death versus severe neurodevelopmental impairment versus survival without severe neurodevelopmental impairment

    Where severe neurodevelopmental impairment is defined as any of the following: cognitive or language delay defined as a cognitive-composite-score or a language-composite-score on the Bayley Scales of Infant and Toddler Development (3rd edition) < 85 and/or cerebral palsy (CP) according to SCPE criteria [SCPE Dev Med Child Neurol 2000]. In case of missing Bayley III test results, Bayley II or other developmental test results or PARCA-R parent questionnaire results may substitute for the Bayley III test result in a predefined hierarchical order.

    Primary endpoint with three mutually exclusive responses (healthy, death, composite outcome for impairment) will be analyzed in the two treatment groups by a generalized logits model according to Bishop, Fienberg, Holland 1975 with SAS 9.4 procedure proc catmod.

    Measured: at the age of 24 months

Secondary outcomes (10)
  1. Death or neurodevelopmental impairment (NDI)

    The primary endpoint will be reconstituted as dichotomised composite secondary endpoint (survival without NDI versus Death or language-composite-score < 85 or cognitive-composite score <85 or cerebral palsy present). In case of missing Bayley III test results, Bayley II or other developmental test results or PARCA-R parent questionnaire results may substitute for the Bayley III test result in a predefined hierarchical order.

    This will be analyzed by Cochrane-Mantel-Haenszel- X²-Test.

    Measured: at 24months

  2. Incidence of Death

    Incidence of death will be analyzed by Cochrane-Mantel-Haenszel- X²-Test.

    Measured: at 24 months

  3. Incidence of CP

    Incidence of CP according to SCPE criteria [SCPE Dev Med Child Neurol 2000] will be analyzed by Cochrane-Mantel-Haenszel- X²-Test.

    Measured: at 24 months

  4. GMFCS-score

    GMFCS-Score for quantification of the effects of cerebral palsy and other motor impairments (adapted from Palisano et al. [Palisano Med Child Neurol 1997]) using the ALBINO-GMFCS-score sheet will be analysed. GMFCS-score consists of six categories. Analysis will be done by using Wilcoxon-Mann-Whitney test.

    Measured: at 24 months

  5. Motor-Composite-Score (Bayley III)

    The numerical data of the motor-composite-score will be analysed using Wilcoxon-Mann-Whitney test. The use of this test accounts for the fact that data will be cut due to lack of sensitivity below 50 points.

    Measured: at 24 months

  6. Motor-Composite-Score dichotomised (Bayley III)

    The motor-composite-score will be dichotomised at the cut-off <85 versus ≥85 and analysed by Cochrane-Mantel-Haenszel- X²-Test.

    Measured: at 24 months

  7. Cognitive-Composite-Score (cognitive subscale, Bayley III)

    The numerical data of the cognitive-composite-score will be analysed using Wilcoxon-Mann-Whitney test. The use of this test accounts for the fact that data will be cut due to lack of sensitivity below 50 points.

    Measured: at 24 months

  8. Cognitive-Composite-Score dichotomised (cognitive subscale, Bayley III)

    The cognitive-composite-score will be dichotomised at the cut-off <85 versus ≥85 and analysed by Cochrane-Mantel-Haenszel- X²-Test.

    Measured: at 24 months

  9. Language-Composite-Score (language subscale, Bayley III)

    The raw numerical data of the language-composite-score will be analysed using Wilcoxon Mann-Whitney test. The use of this test accounts for the fact that data will be cut due to lack of sensitivity below 50 points.

    Measured: at 24 months

  10. Language-Composite-Score dichotomised (language subscale, Bayley III)

    The language-composite-score will be dichotomised at the cut-off <85 versus ≥85 and analysed by Cochrane-Mantel-Haenszel- X²-Test

    Measured: at 24 months
