Sildenafil safety study achieves major milestone

The Pediatric Trials Network (PTN) recently enrolled the fortieth infant in the Safety of Sildenafil in Premature Infants study. This is a major study milestone, as it rounds out the first cohort (or group of study participants).

The study aims to assess the safety of sildenafil in premature infants at risk of bronchopulmonary dysplasia (BPD) and determine preliminary effectiveness and pharmacokinetics (how a drug travels through the body). The study aims to enroll a total of up to 120 participants.

BPD is a common chronic lung disease that can affect premature newborns, often leading to life-long medical problems, prolonged hospitalization, and even death. Approximately 17,500 U.S. infants develop BPD each year.

Sildenafil, which is approved for the treatment of pulmonary hypertension in adults, may help improve lung development and is increasingly being used off-label in premature infants with BPD. However, the efficacy and safety of sildenafil in premature infants at risk for BPD is currently unknown.

“Our hope is that this study benefits premature infants and their families by providing more information on the safest and most effective dose of sildenafil to treat this life-threatening condition,” said Dr. Matthew Laughon, principal investigator and neonatologist at the University of North Carolina Hospitals in Chapel Hill, N.C.
