Brief Summary
The study is to investigate the safety, tolerability, and pharmacokinetics (the determination of the concentration of the administered drug in blood over time) of recombinant Factor VIII Fc fusion protein (rFVIIIFc) in previously-treated subjects with severe hemophilia A.

Outcome Measures
Primary Outcomes (1)
Safety will be assessed by physical examination, vital signs, laboratory changes overtime, adverse events, and assessment of inhibitor (Bethesda) and antibody development against rFVIIIFc.
78 weeks
Secondary Outcomes (3)
Pharmacokinetic parameters will be measured such as, but not limited to Tmax, Cmax, t1/2, CL, Vd, AUC, MRT, and incremental recovery.
78 weeks
To determine the pharmacokinetics parameters after single administration of 25 and 65 IU/kg of rFVIIFc compared to advate
78 weeks
To determine the pharmacodynamic activity of FVIII over time for both doses of rFVIIIFc
78 weeks
Study Arms (2)
A

B
EXPERIMENTALCohort to receive a single high dose intravenous injection of commercially available rFVIII with safety and PK assessments followed by a single high dose intravenous injection of rFVIIIFc with safety and PK assessments
