Brief summary
A phase I study to test the feasibility and safety of treatment with metformin in infants affected by hypoxic ischemic encephalopathy (HIE) or prematurity-related brain injury
Interventions
Infants will receive 14 consecutive doses, once daily, of metformin, with two dose cohorts. Arm 1: Five infants with HIE will be enrolled on the first dose cohort of 20 mg/kg. Once complete, another five infants will be enrolled on the second dose cohort of 25 mg/kg. Arm 2: Five preterm infants will be enrolled on the first dose cohort of 15 mg/kg. Once complete, another five preterm infants will be enrolled on the second dose cohort of 20 mg/kg.
