Clinical Trial Summary

Hypoxic-ischemic encephalopathy (HIE) due to perinatal asphyxia is common and often fatal. Therapeutic hypothermia reduces mortality and morbidity in infants with HIE. Even with the widespread use of therapeutic hypothermia, ~60% of infants with HIE die or have neurodevelopmental impairment. As a result, there is an urgent, unmet public health need to develop adjuvant therapies to improve survival and neurodevelopmental outcomes in this population. Caffeine may offer neuroprotection for infants with HIE by blocking adenosine receptors in the brain and reducing neuronal cell death. In animal models of HIE, caffeine reduces white matter brain injury. Drugs in the same class as caffeine (i.e., methylxanthines) have been shown to be protective against acute kidney injury in the setting of HIE. However, their safety and efficacy have not been studied in the setting of therapeutic hypothermia and their effect on neurological outcomes is not known. Since these drugs reduce injury to the kidney in infants with HIE, they may also reduce injury to the brain. This phase I study will evaluate the pharmacokinetics, safety, and preliminary effectiveness of caffeine as an adjuvant therapy to improve neurodevelopmental outcomes in infants with HIE.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Area Under Plasma Concentration-time at Time t (AUC0-t) for Caffeine	AUC0-t defines area under the plasma concentration-time curve (AUC) from administration to the last quantifiable concentration at time t.	7 samples will be collected with the following optimal sampling windows: 0-15 minutes, 30-60 minutes, 1-3 hours, 3-6 hours, 6-12 hours, 12-18 hours, 15 minutes prior to next dose.
Secondary	Incidence of seizures and necrotizing enterocolitis, which are potential complications of caffeine exposure	Incidence of seizure activity requiring >1 anti-epileptic medication. Necrotizing enterocolitis defined as Bell Stage II or III.	From the first dose of caffeine to 7 days following the final dose.
Secondary	Number of participants with abnormal MRI brain findings based on NICHD Neonatal Research Network score	The NICHD Neonatal Research Network developed and validated an MRI scoring system that categorizes severity of brain injury in the Trial of Hypothermia for Neonatal Hypoxic-Ischemic Encephalopathy.; Score 0: Normal T2 MRI; Score 1A: Minimal cerebral lesions only with involvement of basal ganglia, thalamus; Score 1B: Extensive cerebral lesions; Score 2A: Basal ganglia thalamic, anterior or posterior limb of internal capsule, or watershed infarction; Score 2B: 2A with cerebral lesions; Score 3: Hemispheric devastation	During initial hospitalization, approximately 7-14 postnatal days
Secondary	Number of participants with a Bayley Scales of Infant Development (BSID-III) cognitive, language, or motor composite score < 85	The BSID--III is a series of measurements to assess the motor (fine and gross), language (receptive and expressive), and cognitive development of infants and toddlers and consists of a series of developmental play tasks. The composite scores are scaled to a metric with a range of 40 to 160, a mean of 100, and a standard deviation of 15. Therefore, children with a composite score < 85 are 1 standard deviation below the mean in that area.	18-24 months of age
