Summary

The objective of the trial is to demonstrate that 2-3 times per week prophylaxis therapy with BAY81-8973 is superior to on-demand therapy with BAY81-8973 in patients with severe Hemophilia A. The hypothesis is that prophylaxis will result in fewer bleeds than on-demand treatment.

BIOLOGICALrFVIII (BAY81-8973) on demandParticipants received on-demand treatment with rFVIII (BAY81-8973) assayed by CS/EP (Chromogenic Substrate Assay per European Pharmacopoeia) for 6 months and by CS/ADJ (Chromogenic Substrate Assay/label adjusted to one-stage assay) for 6 months, sequence according to randomization
BIOLOGICALrFVIII (BAY81-8973) prophylaxis low-doseParticipants received low dose prophylaxis treatment at 20, 25 or 30 IU/kg twice per week with rFVIII (BAY81-8973) assayed by CS/EP for 6 months and by CS/ADJ for 6 months, sequence according to randomization.
BIOLOGICALrFVIII (BAY81-8973) prophylaxis high-doseParticipants received high dose prophylaxis treatment at 30, 35 or 40 IU/kg 3 times per week with rFVIII (BAY81-8973) assayed by CS/EP for 6 months and by CS/ADJ for 6 months, sequence according to randomization.
