The purpose of this study is to determine the effect of 3 doses of ADVATE rAHF-PFM on initial recovery (% increase [IU/dL] per IU/kg infused) and major single-infusion pharmacokinetic parameters. The 3 doses are 15, 30, and 50 IU/kg. Prior to each infusion, subjects will not have received treatment with a factor VIII concentrate for at least 3 days. Blood samples will be drawn within 30 minutes pre-infusion and at 0.25, 0.5, 1, 3, 6, 9, 24, 28, 32 and 48 hours post-infusion. A washout period of at least 3 days, but no more than 30 days between the last blood draw and the next infusion will be observed. During participation, subjects will maintain their preexisting treatment regimens with ADVATE rAHF-PFM or other factor VIII concentrate.
