• Target Recruitment: 140

Inclusion Criteria

• Male; 12 to 65 years of age (or Male 18-65 years of age in countries where enrollment of minors is not permitted)
• Subjects with severe hemophilia A (baseline FVIII activity FVIII:C <1%) determined by measurement at the time of screening or from reliable prior documentation (eg, measurement in other clinical trials, result from approved clinical laboratory)
• Previously treated with FVIII concentrate(s) (plasma derived or recombinant) for a minimum of 150 ED
• Immunocompetent. If HIV positive, CD4+ lymphocyte count >200/mm3

Are the trial subjects under 18? yes
Number of subjects for this age range: 40
F.1.2 Adults (18-64 years) yes
F.1.2.1 Number of subjects for this age range 100
F.1.3 Elderly (>=65 years) no
F.1.3.1 Number of subjects for this age range

Exclusion Criteria

• Current evidence of inhibitor to FVIII with a titer = 0.6 BU/mL, measured by the Nijmegen modified Bethesda assay at the time of screening (central laboratory) (BU: Bethesda unit)
• History of inhibitor to FVIII with a titer = 0.6 BU, or clinical history suggestive of inhibitor requiring modification of treatment. Subjects with a maximum historical titer of 1.0 BU on a single measurement but with at least 3 subsequent successive negative results (< 0.6 BU) thereafter are eligible
• Any other inherited or acquired bleeding disorder in addition to Hemophilia A
• Platelet count < 100,000/mm3
• Creatinine > 2x upper limit of normal
• AST or ALT > 5x upper limit of normal (AST: aspartate aminotransferase; ALT: alanine aminotransferase)
• The subject is currently participating in another investigational drug study, or has participated in a clinical study involving an investigational drug within 30 days of study entry. Subjects who are currently participating in an investigational study in which they are treated with a currently marketed FVIII concentrate are not excluded. Subjects currently treated with BAY 81-8973, and who have received at least 100 ED with the investigational product, may continue treatment with the product up to the start of Visit 1.
• Any subject who is receiving chemotherapy, immune modulatory drugs other than anti-retroviral chemotherapy, or chronic use of oral or intravenous (IV) corticosteroids within the last 3 months. Brief courses of prednisone/methyprednisolone (< 14 days) for treatment of disorders such as synovitis, asthma, etc are allowed at the discretion of the treating physician.
