Brief Summary
This pilot study is a randomized, placebo-controlled, clinical trial to measure changes in blood and urine levels of inositol in premature infants at high risk for retinopathy of prematurity (ROP) following repeated doses of inositol. Based on previous studies, the premise is that maintaining inositol concentrations similar to those occurring naturally in utero will reduce the rates of ROP and bronchopulmonary dysplasia in premature infants. The objective is to evaluate pharmacokinetics, safety, and clinical outcomes of multiple doses of three different dose amounts of myo-inositol (provided by Abbott Laboratories) in very low birth weight premature infants. This study will enroll an estimated 96 infants at 17 NICHD Neonatal Research Network sites. Infants will be randomly assigned to receive either 10 mg/kg of 5% inositol, 40 mg/kg of 5% inositol, 80 mg/kg of 5% inositol, or 5% glucose given in the same volumes and timings as the inositol dosage to maintain masking. Enrollees will receive their assigned dose or placebo daily, starting within 72 hours of birth, and continuing until they reach 34 weeks post-menstrual age, 10 weeks chronologic age, or until the time of hospital discharge, whichever occurs first. The study drug will be administered first intravenously; as the infants progress to full feeding, the drug will be given enterally (orally or via feeding tube). Enrollees will be seen for a follow-up examination at 18-22 months corrected age. This pilot study is in preparation for a future Phase III multi-center randomized controlled trial.
