Trial Summary
This non-randomized, multicenter, open-label, Phase III clinical study will evaluate the efficacy, safety, and pharmacokinetics of emicizumab administered subcutaneously initially once weekly (QW) in pediatric participants with hemophilia A with FVIII inhibitors. This study will open two additional non-randomized cohorts to investigate once every 2 weeks (Q2W) and once every 4 weeks (Q4W) regimens in pediatric participants.
