Description of intervention(s) / exposure
Other interventions - rFVIIIFc

Experimental: rFVIIIFc - Participants were to receive rFVIIIFc as follows- Prophylaxis regimen (PR): rFVIIIFc 25-80 international units per kilogram (IU/kg), at 3- to 5-day intervals until participant reached greater than or equal to (>=) 50 exposure days (ED: 24-hour period in which >=1 injection/dose of rFVIIIFc was given), or study withdrawal/end of study. Adjustments to dose/dosing interval was done as needed by investigator; Treatment with an optional ER (Episodic regimen) can be initiated before PR at investigators discretion; ITI: rFVIIIFc 200 IU/kg, daily for participants who, after exposure to rFVIIIFc, had positive high titer inhibitor (>=5.00 Bethesda Units per milliliter [BU/mL]) or positive low titer inhibitor (>=0.60 and <5.00 BU/mL) and had poorly controlled bleeding despite increased rFVIIIFc doses, or required bypassing agent to treat bleeding.

Eligibility
Key inclusion criteria
Key

and dated informed consent and authorization to use confidential health information in
accordance with national and local participant privacy regulations.

- Weight >=3.5 kg at the time of screening.

in the medical record or as tested during the Screening Period.

Key
Minimum age
No limit
Maximum age
5 Years
Sex
Males
Can healthy volunteers participate?
No
Key exclusion criteria
- Any exposure to blood components, factor VIII replacement products, including
commercially available rFVIIIFc at any time prior to or during screening.

- History of positive inhibitor testing. A prior history of inhibitors was defined based
on a patient's historical positive inhibitor test using the local laboratory Bethesda
value for a positive inhibitor test (ie, equal to or above lower level of detection).

- History of hypersensitivity reactions associated with any rFVIIIFc administration.

- Other coagulation disorder(s) in addition to hemophilia A.

- Any concurrent clinically significant major disease that, in the opinion of the
Investigator, would make the participant unsuitable for enrollment.

- Current systemic treatment with chemotherapy and/or other immunosuppressant drugs.

Note: Other protocol defined Inclusion/Exclusion criteria may apply.

Summary
Brief summary
The primary objective of the study was to evaluate the safety of rFVIIIFc (BIIB031) in
previously untreated participants (PUPs) with severe hemophilia A. The secondary objectives
were to evaluate the efficacy of rFVIIIFc in the prevention and treatment of bleeding
episodes in PUPs, to evaluate rFVIIIFc consumption for the prevention and treatment of
bleeding episodes in PUPs, and to describe experience with the use of rFVIIIFc for immune
tolerance induction (ITI) in participants with inhibitors.
