Randomized Clinical Trial of Inhaled PGE1 (IPGE1) in Neonatal Hypoxemic Respiratory Failure. A Protocol for the NICHD Neonatal Research Network
This pilot study was a randomized, placebo-controlled, clinical trial to test the safety of
using the intravenous form of Prostaglandin E1 (PGE1) in an inhaled form for treatment of
hypoxemic respiratory failure in term newborns. The study planned to enroll 50 infants
diagnosed with hypoxemic respiratory failure at nine NICHD Neonatal Research Network sites,
and randomly assign them to receive one dose over a 72-hour period of either high
concentration PGE1 (300 ng/kg/min), low concentration PGE1 (150 ng/kg/min), or placebo
(normal saline, the diluent for the drug). In addition to determining the safety, optimal
dose, and duration of the therapy, this pilot trial planned to evaluate the feasibility of
conducting a larger, multi-center randomized, blinded placebo-controlled trial.

Hypoxemic respiratory failure (HRF), frequently associated with persistent pulmonary
hypertension of the newborn (PPHN), is a rare, but life-threatening condition affecting
approximately 2 to 9 percent of infants admitted to neonatal intensive care units and results
in significant morbidity and mortality. It occurs more often in full- or post-term babies
whose circulatory systems do not adapt well to breathing outside the womb. HRF may result
from congenital hernia of the diaphragm, group B streptococcal infection, inhaling meconium
in the womb, or respiratory distress syndrome.
Medical treatments, such as high frequency ventilation, inhaled nitric oxide, and
Extracorporeal Membrane Oxygenation (ECMO, a heart and lung support machine), have
significantly increased survival of children with HRF. These therapies, while successful,
however, have a variety of side effects and potential long-term disabilities.
This feasibility trial was designed to test the safety of using the intravenous form of
Prostaglandin E1 in an inhaled form (iPGE1) on infants born at 34 0/7ths weeks gestational
age or greater diagnosed with hypoxemic respiratory failure and on assisted ventilation. The
intravenous form of PGE1 was to be aerosolized and administered via a nebulizer attached to
the infant's ventilator. The goal was to enroll 50 subjects within 6-9 months, in preparation
for a larger, multi-center randomized control trial; however, the study was withdrawn for
lack of recruitment.
