The study will consist of two parts: a safety and efficacy period in which all subjects will participate and a pharmacokinetic analysis period, in which 30 eligible subjects will participate to compare ReFacto AF and Advate bioequivalency and safety and efficacy of ReFacto AF in patients with Hemophilia A.
