2. The subject has severe or moderately severe hemophilia A as defined by a baseline factor VIII level less than or equal 2% of normal, as tested at screening.
3. The subject has a documented history of at least 150 exposure days to factor VIII concentrates (either plasma-derived or recombinant).
4. The subject is within 7 to 65 years of age.
5. The subject has a Karnofsky performance score > 60.
6. The subject is human immunodeficiency virus negative (HIV-) or is HIV+ with a stable CD4 count more than or equal 400 cells/mm³ (CD4 count determined at screening, if necessary).
