Steady state volume of distribution (Vss) is the apparent volume of distribution at steady-state which is estimated by (D/AUC[0-infinity])*(AUMC[0-infinity])/AUC[0-infinity]) where D is the dose of study drug, AUMC(0-infinity) is the area under the first moment curve extrapolated to infinity and AUC(0-infinity) is the area under the plasma concentration-time curve from time zero to infinite time. Results were summarized overall for 15K rFVIIIFc 1000 IU/vial and 6000 IU/Vial (PK2).

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.

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.

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.

Summary
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.
