Summary
Brief summary
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.
