Summary

Inhaled nitric oxide (iNO) is an effective treatment for pulmonary hypertension (PH) in term and near-term infants. Preterm infants are at risk for early PH that is associated with high risk for bronchopulmonary dysplasia or death. In multiple clinical trials, iNO treatment was not effective for BPD prevention. However, infants were not screened for PH and iNO treatment was not targeted for PH. iNO treatment for PH in preterm infants is controversial due to lack of evidence. The study team hypothesizes that early diagnosis of PH (72-96 hours of life) and iNO treatment will decrease the incidence of death and bronchopulmonary dysplasia and improve oxygenation in extremely preterm infants.

  1. To determine if iNO treatment of extremely preterm infants with early pulmonary hypertension as established with echocardiographic evidence at 72-96 hours of age will decrease incidence of death or BPD.
  2. To determine if iNO treatment of extremely preterm infants with early PH will decrease the pulmonary artery pressure and improve oxygenation within 72 hours of intervention.

Description

This is a single center, blinded, randomized control clinical trial to evaluate the effects of inhaled nitric oxide on the outcome of survival and incidence of bronchopulmonary dysplasia. This trial has a planned enrollment of 138 infants with 68 infants with delayed pulmonary transition assigned to either the treatment or placebo group. There is no enrollment restriction based on gender, ethnicity, or race. Enrollment is expected to take 36 months with an additional 12 months for data analysis.Infants with early pulmonary hypertension will be randomized to the treatment or placebo group. Treatment will continue until resolution of pulmonary hypertension or through Day 14, whichever comes first. Serial echocardiograms will be performed every 48 hours +/-12 hours until Day 14. Oxygen saturation levels will be averaged every 24 hour period following enrollment. This study will provide evidence for the beneficial effects of early diagnosis and treatment of pulmonary hypertension in preterm infants.
