Caffeine for Hypoxic Ischemic Encephalopathy

CHIME is a randomized, parallel-arm, double-blind, placebo-controlled trial focused on infants with hypoxic ischemic encephalopathy (HIE). The trial will recruit neonates who are diagnosed with HIE within six hours after birth based on physiologic criteria (acidosis noted on an umbilical cord or early \[\<1 hour\] postnatal blood sample) and neurologic criteria (modified Sarnat exam consistent with encephalopathy). Following informed consent, and by six hours after birth, neonates with HIE will be randomized to one of two treatment arms and subsequently receive one 20 mg/kg dose of oral caffeine followed by two additional 10 mg/kg doses at 24-hour intervals or placebo of the same regimen (three total doses). The goal of this clinical trial is to compare the incidence of all-cause mortality OR moderate to severe neurodevelopmental impairment (NDI) at 18-22 months between neonates with HIE who are randomized to oral caffeine or placebo. Our hypothesis is that neonates with HIE who receive oral caffeine will have 10% lower incidence of all-cause mortality or moderate to severe NDI at 18-22 months compared to placebo.
