Title: BAX 855 (PEGylated Recombinant Factor VIII): A Phase 1, Prospective, Open Label, Cross-Over, Dose-Escalation Study in Previously Treated Patients (PTPs) With Severe (FVIII < 1%) Hemophilia A
Brief Summary: The objectives of this study are to assess the tolerability and safety after single dose treatments of BAX 855 in previously treated patients (PTPs) with severe hemophilia A, to determine the pharmacokinetic (PK) parameters of BAX 855 compared in crossover with ADVATE, and to evaluate the impact of anti-polyethylene glycol (PEG) antibodies on PK parameters.


Options:
A: 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).
B: Inclusion Criteria:

* Diagnosed with hemophilia A
* factor level less than 2%

Exclusion Criteria:

* More than 2 bleeds into the same joint
C: Key Inclusion Criteria:

* Severe hemophilia A defined as \<1 IU/dL (\<1%) endogenous FVIII
* Male \<12 years of age and weight ≥13 kg
* History of at least 50 documented prior exposure days to FVIII
* No current, or history of, inhibitor development to FVIII

Key Exclusion Criteria:

* Other coagulation disorders in addition to Hemophilia A
* History of anaphylaxis associated with any FVIII or IV immunoglobulin administration

NOTE: Other protocol-defined Inclusion/Exclusion criteria may apply.
D: Inclusion Criteria:

* The subject is male and is 18 to 65 years of age at the time of screening
* The subject has severe hemophilia A (factor VIII level \< 1%)
* The subject was previously treated with plasma-derived factor VIII (FVIII) concentrates or recombinant FVIII for at least 150 exposure days (EDs)

Exclusion Criteria:

* The subject has a detectable FVIII inhibitor at screening, with a titer \>= 0.6 BU
* The subject has a documented history of FVIII inhibitors with a titer \>= 0.4 BU at any time prior to screening
* The subject has a known hypersensitivity towards mouse or hamster proteins or to polyethylene glycol (PEG)
