Study of Biostate® in Children With Von Willebrand Disease

2 oktober 2017 uppdaterad av: CSL Behring

A Phase III Open-label, Multi-centre Study to Assess the Pharmacokinetics, Efficacy, and Safety of Biostate® in Paediatric Subjects With Von Willebrand Disease

This is an open-label study to investigate the pharmacokinetics (PK), efficacy, and safety of a von Willebrand Factor/Factor VIII (VWF/FVIII), Biostate, in children with Von Willebrand disease (VWD) in whom treatment with a VWF product is required for prophylactic therapy, haemostatic control during surgery, or control of a non-surgical, spontaneous, or traumatic bleeding event.
