Mallinckrodt Reports on FDA Joint Advisory Committee Meeting for Stannsoporfin for the Treatment of Newborns at Risk of Developing Severe Jaundice
Stannsoporfin is a heme oxygenase inhibitor under investigation for the treatment of newborns ≥35 weeks of gestational age with indicators of hemolysis who are at risk of developing severe jaundice, or hyperbilirubinemia. If approved, stannsoporfin would be a first-in-class pharmacologic treatment for severe jaundice in newborns with a novel mechanism of action that inhibits bilirubin production at its source.1 The safety and effectiveness of stannsoporfin have not yet been established by the
ABOUT NEONATAL JAUNDICE
Neonatal, or newborn, jaundice is a condition caused by the build-up of bilirubin, a yellow substance in the blood that is formed as red blood cells break down as part of the body's natural process.2 About three in five babies (60 percent) have jaundice at birth, and most often it goes away without treatment.2 However, in some cases, the newborn is not able to clear excessive levels of bilirubin resulting in an imbalance that leads to a condition called hyperbilirubinemia.2,3 If severe and left untreated, this condition may lead to neurologic complications, including irreversible brain damage.3 The current standard of care for treating severe jaundice is phototherapy, which targets the excess bilirubin that has accumulated in the baby's bloodstream and helps the body to control the bilirubin.4 However, it does not address bilirubin production.3
