A phase I trial of caffeine to evaluate safety in infants with hypoxic-ischemic encephalopathy.

OBJECTIVE: Caffeine provides neuroprotection following hypoxic-ischemic injury in animals. We characterized the safety of escalating doses of caffeine in infants with hypoxic-ischemic encephalopathy (HIE) receiving therapeutic hypothermia. STUDY DESIGN: Phase I trial of infants undergoing therapeutic hypothermia for HIE receiving IV caffeine 20 mg/kg followed by up to two daily doses of 5 mg/kg (n = 9) or 10 mg/kg (n = 8). Safety was evaluated based on adverse events and frequency of pre-specified outcomes compared to data from the Whole-Body Hypothermia for HIE trial (Shankaran, 2005). RESULTS: Twelve of 17 (71%) infants had ≥1 adverse event during the study period. The frequency of clinical outcomes related to HIE were not statistically different from outcomes in infants receiving hypothermia in the Whole-Body Hypothermia for HIE trial. CONCLUSION: Caffeine administration was well tolerated. A larger study is required to determine the optimal dose and evaluate drug safety and efficacy. CLINICAL TRIAL: ClinicalTrials.gov Identifier: NCT03913221.
