Bronchopulmonary Dysplasia Clinical Trial
Official title:
Phase 1 Intravenous Citrulline for the Prevention of Bronchopulmonary Dysplasia in Preterm Infants
Premature infants are at risk for developing bronchopulmonary dysplasia (BPD). L-citrulline may decrease that risk, but we do not know the safety or dose of this drug for use in premature babies. The purpose of this study is to determine the safety and optimal dose of intravenous L-citrulline in premature infants.
This is a prospective phase I study of the safety, pharmacokinetics, and optimal dose of intravenously administered L-citrulline in premature infants born at 24 to 29 weeks estimated gestational age (EGA) and who are at risk for bronchopulmonary dysplasia (BPD). This is a classic dose escalation using initial doses of 10 mg/kg of intravenous citrulline and advancing the dose by 10 mg/kg every 3 patients for a target peak plasma citrulline concentration of 100 umol/L. These infants will undergo intense hemodynamic monitoring and have intermittent blood sampling to determine levels of amino acids and nitric oxide metabolites. From this, we will determine citrulline pharmacokinetics including half life, clearance, and volume of distribution. Intravenous L-citrulline will be provided by Asklepion Pharmaceuticals and mixed by the Investigational Drug Service of the Vanderbilt Hospital Clinical Pharmacy. The study will be monitored closely by a data safety monitoring board (DSMB) consisting of clinicians not involved with this study. ;
