A Phase 2/3, Multi-Center, Open Label Study of Efficacy, Safety, and Pharmacokinetics of PEGylated Recombinant Factor VIII (BAX 855) Administered for Prophylaxis and Treatment of Bleeding in Previously Treated Patients With Severe Hemophilia A

To assess efficacy and safety, including immunogenicity of BAX 855 administered as
prophylaxis and as on-demand therapy in adult and adolescent (12-65 years) previously treated
patients (PTPs) with severe hemophilia A To determine the pharmacokinetic (PK) parameters of
BAX 855.


Main Inclusion Criteria:

- Participant and/or legal representative has/have voluntarily provided signed informed
consent

- Participant is 12 to 65 years old at the time of screening

- Participant is male with severe hemophilia A (Factor VIII (FVIII) clotting activity <
1%) as confirmed by central laboratory at screening after the appropriate washout
period or a documented FVIII clotting activity <1%

- Participant has been previously treated with plasma-derived FVIII concentrates or
recombinant FVIII for ≥150 documented exposure days (EDs)

- Participant is currently receiving prophylaxis or on-demand therapy with FVIII

- Participant is willing and able to comply with the requirements of the protocol

Main Exclusion Criteria:

- Participant has detectable FVIII inhibitory antibodies (≥ 0.6 Bethesda Units (BU)
using the Nijmegen modification of the Bethesda assay) as confirmed by central
laboratory at screening

- Participant has history of FVIII inhibitory antibodies (≥ 0.4 BU using the Nijmegen
modification of the Bethesda assay or ≥ 0.6 BU using the Bethesda assay) at any time
prior to screening

- Participant has been diagnosed with an inherited or acquired hemostatic defect other
than hemophilia A (eg, qualitative platelet defect or von Willebrand's disease).
