Clinical Trial Summary

This is a phase Ib, open-label, dose-validating and safety study of caffeine in neonates with hypoxic-ischemic encephalopathy (HIE) undergoing therapeutic hypothermia.

Description:

In a previous phase I trial (NCT03913221), the investigators characterized the pharmacokinetics (PK) of caffeine in the setting of HIE and therapeutic hypothermia using a population PK model. This is an open-label study of caffeine citrate in neonates with HIE to validate the population PK model and determine optimal dosing for HIE.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Apparent Caffeine Clearance	Clearance is a measure of the rate at which a drug is metabolized or eliminated by normal biological processes. Caffeine concentrations will be used to calculate population estimates of caffeine clearance, with inter-individual variabilty and residual variabilty .	7 samples will be collected after the first dose of study drug and up to 72 hours after final dose of study drug
Primary	Volume of Distribution of Caffeine	Caffeine concentrations will be used to calculate population estimates of volume of distribution with inter-individual variability and residual variability.	7 samples will be collected after the first dose of study drug and up to 72 hours after final dose of study drug
Secondary	Number of Participants with Pre-Specified Adverse Events	Safety will be determined by the number of participants with the following: seizures requiring > 1 anti-epileptic drug, necrotizing enterocolitis defined as Bell Stage II or higher, hypoglycemia defined as point-of-care blood glucose < 30 mg/dL, and hyperglycemia defined as point-of-care blood glucose >200 mg/dL.	From the first dose of caffeine to 7 days following the final dose.
Secondary	Number of Participants with Abnormal MRI Brain Finding Score	Preliminary effectiveness assessed using the NICHD Neonatal Research Network MRI scoring system that categorizes severity of brain injury in the Trial of Hypothermia for Neonatal Hypoxic-Ischemic Encephalopathy. Abnormal MRI is defined as any score >0.; Score 0: Normal 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, typically 3-5 postnatal days
Secondary	Number of Participants with Death or Neurodevelopmental Impairment	Preliminary effectiveness assessed based on death or neurodevelopmental impairment defined as: diagnosis of cerebral palsy, hearing impairment requiring hearing aids, blindness, or cognitive, language, or motor score < 85 on the Bayley Scales of Infant and Toddler Development- Fourth Edition.	18-24 months of age
