BioCryst announced that the Food and Drug Administration (FDA) has expanded the use of Rapivab (peramivir injection) to pediatric patients aged ≥2 years with acute uncomplicated influenza who have been symptomatic for no more than 2 days. 

Prior to the approval, Rapivab was indicated for use in patients aged ≥18 years. The pediatric approval was supported by interim data from an analysis of an ongoing pediatric clinical study. The findings will be presented at the upcoming IDWeek 2017 Meeting in San Diego, CA.
