Could a common heart drug protect newborn brains? small trial launches
NCT ID NCT06810284
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This phase 2 study will test how the drug sildenafil (Revatio) is processed in the bodies of 24 full-term newborns who experienced oxygen deprivation at birth and are already receiving standard cooling therapy. The goal is to measure drug levels and prepare for a larger trial that would check if adding sildenafil to cooling helps babies survive without brain damage. The study is not yet recruiting.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- sildenafil citrate (Revatio)
- What this could lead to
- If successful, this could pave the way for a larger study testing whether combining sildenafil with cooling therapy helps newborns survive without brain damage after oxygen deprivation at birth.
- What could go wrong
- This is a very early, small study (24 babies) focused only on drug levels, not on whether the treatment actually works. The drug may not improve outcomes or could cause side effects in fragile newborns.

Inclusion Criteria: * 1/Neonates born at or after 36 weeks' gestation, treated by therapeutic servo-controlled hypothermia for neonatal hypoxic ischemic encephalopathy. Therapeutic hypothermia should be decided according to French national guidelines. * 2/ Social security coverage * 3/ Informed consent of one of the two holders of parental authority. Exclusion Criteria: * 1/ Chromosomal aberrations and major malformations evidenced after birth * 2/ Decision for "comfort care only" before study drug administration, * 3/ Uncontrolled hemorrhagic syndrome, * 4/ Severe hemodynamic failure at initiation, requiring at least two therapies (including either volume expansion, hydrocortisone or inotropes) * 5/ Known hypersensitivity to the active substance or to any of the excipients * 6/ Concomitant administration of nitrates or nitric oxide donors, Inhaled Nitric Oxide, other PDE5 inhibitors, inhibitors of CYP3A4 * 7/ Participation in another interventional study
