Summary

The purpose of this study is to compare the hemostatic efficacy and safety of continuous infusion versus intermittent bolus infusion in the peri- and post-operative setting, employing rAHF-PFM, a recombinant antihemophilic factor manufactured without added human or animal proteins, in previously treated patients with severe or moderately severe hemophilia A (baseline factor VIII level \<= 2% of normal) who are undergoing unilateral major orthopedic surgery that requires drain placement. The total study period per subject (from consent to study completion) will vary from approximately 9 to 26 weeks and will involve clinical and laboratory assessments.

Conditions

Interventions

DRUG

Recombinant Protein-Free Factor VIII (rAHF-PFM)

An initial loading dose will be administered intravenously over a period \<= 5 minutes (maximum of infusion rate of 10 mL/minute) within 60 minutes prior to surgery dose in order to maintain a minimum target FVIII level of at least 80% of normal. CI will start prior to surgery as soon as the loading dose has been administered, at a rate calculated according to a formula provided by the sponsor. All study product must be administered with a syringe pump running at an infusion rate according to the dosing regimen, but always \>= 0.4 mL/h.

DRUG

Recombinant Protein-Free Factor VIII (rAHF-PFM)

The treatment schedule for intermittent BI of rAHF-PFM will begin with the administration of the loading dose according to the dose recommendations provided by the sponsor. If required by the hemostatic challenge, additional boluses may be administered after a blood sample for FVIII determination has been drawn. All infusions of rAHF PFM will be given over a period \<= 5 minutes (maximum infusion rate, 10 mL/min).
