Participant is <6 years old at the time of screening.
Must not have
Participant has detectable FVIII inhibitory antibodies (>=0.6 BU using the Nijmegen modification of the Bethesda assay) as confirmed by central laboratory at screening.
Spontaneous disappearance of the inhibitor prior to ITI.

Summary

This trial is for young children with severe hemophilia A who have not been treated with BAX855 or other FVIII concentrates. The goal is to check for side effects and learn how well BAX855 controls bleeding.

Who is the study for?
This trial is for children under 6 with severe hemophilia A who haven't been treated with BAX855 or similar treatments. They must have had less than three exposures to certain medications and no history of severe allergic reactions to specific proteins, PEG, or Tween 80. Their liver and kidney functions should be normal, and they shouldn't be on other PEGylated drugs or certain immune-modifying drugs.Check my eligibility
What is being tested?
The study tests BAX855 in young children with hemophilia A for side effects, including the development of antibodies that may reduce its effectiveness. The drug can be used as a regular preventive treatment or given when bleeding occurs. If antibodies develop, additional treatment will be provided within the study.See study design
What are the potential side effects?
Possible side effects include allergic reactions to ingredients in BAX855 like mouse or hamster proteins, PEG, or Tween 80. There's also a risk of developing inhibitors (antibodies) against Factor VIII which could make the treatment less effective.

Experimental Treatment
Group I: Previously untreated patients (PUPs)Experimental Treatment2 Interventions
Part A (Main Study): Participants age <3 years and not experienced two joint bleeds will receive on- demand treatment of 10-80 international unit per kilogram (IU/kg) of BAX 855 intravenously depending on the severity of the bleeding episode and age <3 years or after a maximum of two joint bleeds will receive prophylaxis treatment with dose of 25-80 IU/kg of BAX855 IV (based on investigator discretion) once weekly for up to 100 EDs. Part A (Surgery): In participants, the administration of BAX 855 will be individualized based on the participants IR and half-life. For major surgery to achieve the target level of 80-100% FVIII in plasma of normal FVIII level and for minor surgery >=30-60% FVIII levels for dental or other invasive surgery. Part B (Immune tolerance induction [ITI]): Participants will receive prophylaxis treatment of 100-200 IU/kg BAX 855 IV daily or 50 IU/kg three time in a week and will be reduced to twice weekly to maintain FVIII trough level of 1% for further 3 months.
