Intermittent Hypoxia and Caffeine in Infants Born Preterm (ICAF)

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Intermittent Hypoxia and Caffeine in Infants Born Preterm (ICAF) Our proposal will address the critical question: is persisting intermittent hypoxia (IH) in preterm infants associated with biochemical, structural, or functional injury, and is this injury attenuated with extended caffeine treatment? The investigators will study the effects of caffeine on IH in 220 preterm infants born at ≤30 weeks + 6 days gestation. Infants who are currently being treated with routine caffeine, and who meet eligibility criteria, will be enrolled between 32 weeks + 0 days and 36 weeks + 6 days PMA. At enrollment, infants will be started on continuous pulse oximeter recording of O2 saturation and heart rate. If, based on standard clinical criteria, the last dose of routine caffeine is given on or before the day the infant is 36 weeks + 5 days PMA, then on the day following their last dose of routine caffeine treatment, infants will be randomized (110/group) to extended caffeine treatment or placebo. Randomized infants should begin receiving study drug (i.e. 5 mg/kg/of caffeine base, or equal volume of placebo) on the day of randomization, but no later than the third calendar day following the last dose of routine caffeine. Prior to 36 weeks + 0 days PMA, study drug will be given once daily (i.e. 5mg/kg/day) and beginning at 36 weeks + 0 days PMA, study drug will be given twice daily (i.e. 10 mg/kg/day). The last dose of study drug will be given at 42 weeks + 6 days PMA. Pulse oximeter recordings will continue 1 additional week after discontinuing study drug. Two caffeine levels will be obtained, the 1st at one week after beginning study drug, and the 2nd at a target date of 40 weeks + 0 days PMA, but no later than the last day of study drug, whether in hospital or at home. Inflammatory biomarkers will be measured at study enrollment and again at 38 weeks + 0 days PMA, or within 2 calendar days prior to hospital discharge, whichever comes first. Quantitative MRI/MRS should be obtained between study enrollment and 3 calendar days after starting study drug and again at a target date of 43 weeks + 0 days, but no later than 46 weeks + 6 days PMA.
