The objective of this study is to further evaluate observations of decreased efficacy in subjects having been switched to Advate rAHF-PFM from Recombinate rAHF by comparing the pharmacokinetic parameters of the two products in previously treated patients with severe hemophilia A (factor VIII level < 1%) in whom decreased efficacy with Advate rAHF-PFM compared to Recombinate rAHF was observed. MedDRA version: 9.1 Level: LLT Classification code 10066439 Term: Hemophilia
