Eligibility
Inclusion criteria
Inclusion criteria: Neonates with a prenatally (before birth) or postnatally (after birth) confirmed diagnosis of critical congenital heart disease requiring (anticipated) cardiac surgery with cardiopulmonary bypass (within the first 4 weeks of life). Are the trial subjects under 18? yes Number of subjects for this age range: 236 F.1.2 Adults (18-64 years) no F.1.2.1 Number of subjects for this age range F.1.3 Elderly (>=65 years) no F.1.3.1 Number of subjects for this age range
Exclusion criteria
Exclusion criteria: - Inability to enroll the patient before the start of delivery in case of prenatal diagnosis, or 24 hours before surgery in case of postnatal diagnosis. - Gestational age below 36 weeks and/or birth weight less than 2000 gram. - Surgery not requiring cardiopulmonary bypass. - Patient considered “moribund”. - Decision for “comfort care only”.
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: To evaluate whether in newborns with critical congenital heart disease, early postnatal (after birth) and perioperative (around cardiac surgery with cardiopulmonary bypass) allopurinol compared to placebo (mannitol) administration reduces relevant (moderate/severe) parenchymatous brain injury on postoperative MRI. ;Secondary Objective: To evaluate the effect of allopurinol on: - Brain injury severity score and volume of hypoxic-ischemic injury (MRI). - Brain function (amplitude integrated electroenchepalogram) and oxygenation (near-infrared spectroscopy). - Cardiac function (echocardiography). - Neurodevelopmental outcome (general movements, Bayley scales of infant development and executive functioning). - Quality of life. - Cost-effectiveness of allopurinol. ;Primary end point(s): Primary outcome is a composite endpoint of relevant (moderate/severe) parenchymatous brain injury on postoperative MRI or too instable for postoperative MRI or mortality ;Timepoint(s) of evaluation of this end point: Primary endpoint will be measured at postoperative MRI. The postoperative MRI takes place 5 to 10 days (and at least within 1 month) after cardiac surgery with cardiopulmonary bypass, which is usually within the neonatal period (first month of life). | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): Secondary outcome measures are: - Brain injury severity score and volume of hypoxic-ischemic brain injury (pre- and postoperative MRI) - Brain function: background pattern and seizure activity (postnatal and perioperative amplitude integrated electroenchepalogram). - Brain oxygenation (postnatal and perioperative near-infrared spectroscopy). - Cardiac function (pre- and postoperative echocardiography). - Neurodevelopmental outcome (general movements at 3 months and Bayley scales of infant development and executive functioning testing at 24 months). - Quality of Life (TNO-TAPQOL at 24 months). - Cost-effectiveness of allopurinol (questionnaires during hospital stay, at 3 and 24 months). - Pharmacokinetics of allopurinol (substudy: postnatally, perioperatively). ;Timepoint(s) of evaluation of this end point: Timepoints of each endpoint evaluation are mentioned in E.5.2. All endpoints will be expected within the neonatal period (first month of life) except neurodevelopmental outcome assessment and quality of life and cost-effectiveness questionnaires which takes place (also) at 3 and 24 months of age. | — |
