In Brief
A Phase 3 clinical trial evaluating Recombinant Factor VIII (Kovaltry, BAY81-8973) for Haemophilia A. Completed, enrolled 94 participants across 43 sites in 17 countries.
Detailed Summary
The primary objective was to evaluate the safety and efficacy of the treatment with BAY81-8973 for prophylaxis and treatment of breakthrough bleeds in children with severe hemophilia A. The secondary objectives were * To assess the safety and efficacy of BAY81-8973 during surgeries. * To assess incremental recovery of BAY81-8973. * To assess pharmacokinetic (PK) parameters in a subset of children (Previously treated patients \[PTPs\] and previously untreated patients \[PUPs\] / minimally treated patients \[MTPs\] - participation in PK sampling was voluntary and required consent).

Interventions
Main study: 25-50 IU/kg at least 2x/week for 6 months and at least 50 EDs, IV infusion; Extension study: 25-50 IU/kg at least 2x/week for at least 100 cumulative EDs (main study - Part A and extension study), IV infusion. Exposure day (ED): An ED is a unit of time (1 day) in which replacement treatment of Hemophilia is given to a patient.
Main study: 15-50 IU/kg at least 1x/week for at least 50 EDs or until inhibitor development, IV infusion; Extension study: For participants having reached at least 50 EDs in main study - Part B: 25-50 IU/kg at least 2x/week for at least 100 cumulative EDs (main study - Part B and extension study), IV infusion. For participants who developed an inhibitor in main study - Part B: up to 200 IU/kg per day or 100 IU/kg twice a day at the discretion of the investigator and coordinating investigator until successful eradication of the inhibitor, or until failure, for up to18 months (treatment beyond 18 months required an agreement with the sponsor and coordinating investigator), IV infusion
