Trial design

Randomised, intervention: allopurinol (acepurin / allopurinol sodium) administered intravenously; dosing described as 20 mg/kg body weight per dose (formulation adapted to 100 mg per vial for neonates), given early postnatally and perioperatively around cardiac surgery. comparator arm: placebo mannitol 100mg pfi, administered intravenously (placebo control). Phase III trial across 3 sites in Netherlands.

Eligibility

Recruits 236 paediatric patients.

Vulnerable Population
The trial population consists of neonates (a vulnerable population). Subject information and informed consent forms are provided for prenatal and postnatal diagnosis (documents: L1_SIS ICF prenatale diagnose nl UMCU_CLEAN; L1_SIS ICF postnatale diagnose nl UMCU_CLEAN; L1_SIS ICF prenatale diagnose nl UMCG_CLEAN; L1_SIS ICF postnatale diagnose nl UMCG_CLEAN; L1_SIS ICF postnatale diagnose nl EMC_CLEAN; L1_SIS ICF prenatale diagnose nl EMC_CLEAN), indicating parental consent procedures for enrollment (no separate assent process for participants is described in the available materials).

Inclusion criteria

  • {"criterion_text":"-Neonates with a prenatally (before birth) or postnatally (after birth) confirmed diagnosis of critical congenital heart disease requiring neonatal cardiac surgery with cardiopulmonary bypass within the first 4 weeks of life"}

Exclusion criteria

  • {"criterion_text":"-Inability to enroll the patient before the start of delivery, in case of prenatal diagnosis or 24h before surgery in case op postnatal diagnosis."}
  • {"criterion_text":"-Doubt whether the aortic arch anomaly before birth requires cardiac surgery with CPB in the neonatal period."}
  • {"criterion_text":"-Gestational age below 36 weeks and /or birth weight less than 2000 gram."}
  • {"criterion_text":"-Patient considered \"moribund\"."}
  • {"criterion_text":"-Decision for \"comfort care only\""}
  • {"criterion_text":"-Surgery not requiring cardiopulmonary bypass."}

Endpoints

Primary endpoints

  • {"endpoint_text":"-Primary outcome is a composite endpoint of relevant (moderate / severe) parenchymatous brain injury on postoperative MRI or too instable for postoperative MRI or mortality.","definition_or_measurement_approach":"Composite measured by postoperative brain MRI assessing moderate/severe parenchymatous brain injury; or classification if the patient is clinically too unstable to undergo postoperative MRI; or all-cause mortality."}

Secondary endpoints

  • {"endpoint_text":"-Brain injury severity score and volume of hypoxic-ischemic brain injury (pre- and postoperative MRI)","definition_or_measurement_approach":"Pre- and postoperative MRI to assess brain injury severity score and quantify volume of hypoxic-ischemic injury."}
  • {"endpoint_text":"-Brain function: background pattern and seizure activity (postnatal and perioperative amplitude integrated electroencephalogram).","definition_or_measurement_approach":"Amplitude-integrated electroencephalogram recordings postnatally and perioperatively to evaluate background pattern and seizure activity."}
  • {"endpoint_text":"-Cerebral oxygenation (postnatal and perioperative near-infrared spectroscopy).","definition_or_measurement_approach":"Near-infrared spectroscopy measurements postnatally and perioperatively to assess cerebral oxygenation."}
  • {"endpoint_text":"-Cardiac function (pre- and postoperative echocardiography).","definition_or_measurement_approach":"Echocardiography performed pre- and postoperatively to evaluate cardiac function."}
  • {"endpoint_text":"-Neurodevelopmental outcome (general movements at 3 months and Bayley scales of infant development and executive functioning testing at 24 months).","definition_or_measurement_approach":"General movements assessment at 3 months; Bayley Scales of Infant Development and executive functioning tests at 24 months to assess neurodevelopment."}
  • {"endpoint_text":"-Quality of life (TNO-TAPQOL at 24 months)","definition_or_measurement_approach":"TNO-TAPQOL questionnaire administered at 24 months to assess quality of life."}
  • {"endpoint_text":"-Cost effectiveness of allopurinol (questionnaires during hospital stay at 3 and 24 months)","definition_or_measurement_approach":"Health economics questionnaires administered during hospital stay and at 3 and 24 months to evaluate cost-effectiveness."}

Consent Approach
Informed consent is handled via subject information and informed consent forms for prenatal and postnatal diagnosis (site-specific ICF documents available for UMCU, UMCG, EMC). These documents indicate parental consent is required for enrollment of neonates. ICF document filenames include 'nl', indicating Dutch language documents are provided. No participant assent process is described in the available materials.
