A Trial to Compare Prophylaxis Therapy to On-demand Therapy With a New Full Length Recombinant FVIII in Patients With Severe Hemophilia A (Leopold II)
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.
