|---|---|
| Main Objective: To determine the pharmacokinetics of human-cl rhFVIII in terms of the FVIII coagulant activity (FVIII:C) and to compare it with the licensed FVIII concentrate Kogenate/Helixate in previously treated subjects suffering from severe hemophilia A.;Secondary Objective: To calculate the incremental recovery of FVIII:C for human-cl rhFVIII. To investigate the immunogenic potential of human-cl rhFVIII. To assess clinical efficacy and safety of human-cl rhFVIII in the treatment of bleeding episodes (BE). To assess clinical efficacy and safety of human-cl rhFVIII in surgical prophylaxis.;Primary end point(s): To compare the AUC of human-cl rhFVIII and Kogenate/Helixate for FVIII:C (normalized for the administered dose) using both the chromogenic (CHR) and the one-stage (OS) assay and the actual potency of human-cl rhFVIII and Kogenate/Helixate. | — |
