Key Inclusion Criteria:

  • Have severe hemophilia A, defined as <1 IU/dL (<1%) endogenous FVIII as determined by one-stage clotting assay from the central laboratory at Screening.
  • Previously treated subject, defined as having at least 150 documented prior exposure days (EDs) to any recombinant and/or plasma-derived FVIII and/or cryoprecipitate products at Day 1. Fresh frozen plasma treatment must not be considered in the count for documented exposure days.
  • No history of a positive inhibitor test or clinical signs of decreased response to FVIII administrations. Family history of inhibitors will not exclude the subject.
  • No measurable inhibitor activity using the Nijmegen-modified Bethesda assay (>=0.6 Bethesda Unit per milliliter [BU/mL] is considered positive) at Screening.

Key Exclusion Criteria:

  • Current enrollment in any interventional clinical study in which an investigational drug or approved therapy for investigational use is administered within 30 days prior to the Baseline Visit OR prior participation in any of the following Biogen studies: 998HA101 (NCT01027377), 997HA301 (NCT01181128), 8HA02PED (NCT01458106), 997HA307 (NCT02083965), and 8HA01EXT (NCT01454739).
  • Previous participation in this study.
  • Any concurrent clinically significant major disease that, in the opinion of the Investigator or Biogen, makes the subject unsuitable for participation in the study.

Number of Participants With Treatment Emergent Adverse Events (TEAEs) at 15K Manufacturing Scale
An AE is any untoward medical occurrence in a patient or clinical investigation participant administered a pharmaceutical product and that does not necessarily have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product. Number of Participants with TEAEs were summarized overall.
Number of Participants With Treatment Emergent Serious Adverse Events (TESAEs) at 15K Manufacturing Scale
An SAE is any untoward medical occurrence that at any dose: results in death or in the view of the Investigator, places the participant at immediate risk of death (a life-threatening event); requires inpatient hospitalization or prolongation of existing hospitalization; results in persistent or significant disability/incapacity; or results in a congenital anomaly/birth defect. All major surgeries will be reported as SAEs. An SAE may also be any other medically important event that, in the opinion of the Investigator, may jeopardize the participant or may require intervention to prevent one of the other outcomes listed in the SAE definition. Number of participants with TESAEs were summarized overall.

5. Study Description

Brief Summary
The primary objective of the study is to compare the pharmacokinetic (PK) of recombinant coagulation factor VIII Fc fusion protein (rFVIIIFc) manufactured at the current scale of 2000 L (2K) to the PK of rFVIIIFc manufactured at the 15,000 L (15K) scale in previously treated participants with severe hemophilia A. The secondary objectives are: to characterize the PK of rFVIIIFc manufactured at the 15K scale at the 15K baseline and after 13 weeks of treatment; to characterize the PK of rFVIIIFc manufactured at the 15K scale at 1000 IU/vial and 6000 IU/vial strengths; and to evaluate the safety of rFVIIIFc manufactured at the 15K scale.
Detailed Description
PK assessments are in 3 phases: Pharmacokinetic Assessment 1(PK1): PK assessments following single injection of rFVIIIFc manufactured at the 2K scale. Pharmacokinetic Assessment 2 (PK2): PK assessments are made following a single injection of rFVIIIFc manufactured at the 15K scale where participants are randomized to the 1000 IU vial or 6000 IU/vial strengths. Pharmacokinetic Assessment 3 (PK3): PK assessments are made following 13 weeks of rFVIIIFc treatment manufactured at the 15K scale where participants are randomized to the 1000 IU vial or 6000 IU/vial strengths. After study completion, in countries where rFVIIIFc is not commercially available, eligible participants will be offered enrollment into a long-term safety and efficacy extension study (8HA01EXT [NCT01454739]).

The Mean Residence Time (MRT) is the average time at which the number of absorbed molecules reside in the body, after single-dose administration, and calculated as area under the first moment curve AUMC (0-infinity)/Area Under the Plasma Concentration-Time Curve AUC (0-infinity), where AUMC (0-infinity) is area under the plasma concentration-time first moment curve from time zero to infinite time and AUC (0-infinity) is the area under the plasma concentration-time curve from time zero to infinite time.

Development of Inhibitors as Measured by the Nijmegen-modified Bethesda Assay
Description
An inhibitor test result greater than or equal to (>=)0.6 Bethesda units [BU]/mL, confirmed on 2 separate samples drawn 2 to 4 weeks apart, was considered positive. The test was performed by the central laboratory using the Nijmegen-modified Bethesda Assay. An exact 95% confidence interval (CI) for the percentage of participants with a confirmed inhibitor was calculated using the Clopper-Pearson method for a binomial proportion. Percentage of participants with confirmed inhibitor development was summarized overall.
Time Frame

Number of Participants With Treatment Emergent Adverse Events (TEAEs) at 15K Manufacturing Scale
Description
An AE is any untoward medical occurrence in a patient or clinical investigation participant administered a pharmaceutical product and that does not necessarily have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product. Number of Participants with TEAEs were summarized overall.
Time Frame
Approximately 43 weeks
Title
Number of Participants With Treatment Emergent Serious Adverse Events (TESAEs) at 15K Manufacturing Scale
Description
An SAE is any untoward medical occurrence that at any dose: results in death or in the view of the Investigator, places the participant at immediate risk of death (a life-threatening event); requires inpatient hospitalization or prolongation of existing hospitalization; results in persistent or significant disability/incapacity; or results in a congenital anomaly/birth defect. All major surgeries will be reported as SAEs. An SAE may also be any other medically important event that, in the opinion of the Investigator, may jeopardize the participant or may require intervention to prevent one of the other outcomes listed in the SAE definition. Number of participants with TESAEs were summarized overall.
Time Frame
Approximately 43 weeks

Fresh frozen plasma treatment must not be considered in the count for documented exposure days. No history of a positive inhibitor test or clinical signs of decreased response to FVIII administrations. Family history of inhibitors will not exclude the subject. No measurable inhibitor activity using the Nijmegen-modified Bethesda assay (>=0.6 Bethesda Unit per milliliter [BU/mL] is considered positive) at Screening.

Previous participation in this study. Any concurrent clinically significant major disease that, in the opinion of the Investigator or Biogen, makes the subject unsuitable for participation in the study. Other coagulation disorder(s) in addition to hemophilia A. History of hypersensitivity or anaphylaxis associated with FVIII or intravenous (IV) immunoglobulin administration. NOTE: Other protocol-defined inclusion/exclusion criteria may apply.
