Abstract

Methods Patients included in this post hoc analysis of prospectively collected data were between 10 and 18 yr old with type I or II HAE and a documented history of abdominal or facial attacks. Patients received a single injection of pdC1‐INH concentrate (Berinert®, CSL Behring, Marburg, Germany) 20 U/kg. Efficacy end‐points were time from the administration of study drug to onset of symptom relief and time to complete relief of all symptoms. Results Seven pediatric patients were included in I.M.P.A.C.T.1 with only 1 attack analyzed per patient. Median time to onset of relief was 0.42 h and to complete resolution was 8.08 h.
