| Main Objective: To assess clinical efficacy of Human-cl rhFVIII in terms of prevention and treatment of (breakthrough) bleeding episodes;Secondary Objective: • to determine pharmacokinetics (in 50% of the subjects included) of Human-cl rhFVIII in terms of the AUC, the in-vivo half-life (T1/2), in-vivo recovery, Cmax, Tmax, MRT, Vss, and CL; the results are compared with those obtained from a PK determination with the previously used FVIII concentrate; • to determine the incremental recovery of Human-cl rhFVIII – also over time; • to investigate the immunogenic potential of Human-cl rhFVIII by assessing the inhibitor titre; • to assess efficacy of Human-cl rhFVIII in surgeries; • to assess safety of Human-cl rhFVIII in terms of adverse event monitoring. ;Primary end point(s): Primary Endpoints: 1.) Efficacy of Prophylactic Treatment: Subjects are all treated prophylactically. The frequency of breakthrough bleeds under prophylactic treatment will be calculated. Study drug consumption data (FVIII IU/kg, extrapolated to monthly and yearly usage) both per subject and in total will be evaluated. The following parameters will be documented: • Dates and times of study product injections. • Details of dose(s) used for prophylactic treatment (in IU FVIII). 2.) Efficacy of On-Demand Treatment of Breakthrough Bleeding Episodes For all BEs occurring in the course of the study period the following parameters will be documented: • Details of the respective BE (see Section 6.1.4). • Efficacy assessment at the end of the BE (see Section 6.1.4.1). • Details of date, time, dose and batch number used to treat BE (in IU FVIII) (see Section 6.1.4.1 of the protocol) | — |
