Ages Eligible for Study:   up to 6 Years   (Child)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Subject is less than 6 years of age
  • Severe or moderately-severe hemophilia A as defined by a baseline factor VIII level <= 2%, documented at screening or on the basis of historical data (e.g., at hemophilia diagnosis)
  • Documented medical history of at least 50 exposure days for treatment with all other factor VIII products
  • Subject's parent or legally authorized representative has provided informed consent

Exclusion Criteria:

  • Detectable inhibitor to factor VIII measured in the screening sample by the local or central hemostasis laboratory
  • History of inhibitor to factor VIII at any time prior to screening
  • Subject has any one of the following laboratory abnormalities at the time of screening:

    1. platelet count < 100,000/mm3
    2. hemoglobin concentration < 10 g/dL (100 g/L)
    3. serum creatinine > 1.5 times the ULN for age
    4. total bilirubin > 2 times the ULN for age
  • Subject has an inherited or acquired hemostatic defect other than hemophilia A (e.g., platelet dysfunction secondary to uremia, liver failure, von Willebrand's Disease)
  • Subject has known hypersensitivity to RECOMBINATE rAHF
  • Subject is currently participating in another investigational drug study or has participated in any clinical study involving an investigational drug within 30 days of study entry
  • Subject is identified by the investigator as being unable or unwilling to cooperate with study procedures
