Inclusion criteria

  • Age >= 5 years
  • The subject has severe or moderately severe hemophilia A defined by a baseline factor VIII level <= 2% of normal documented at screening or historically (e.g., at hemophilia diagnosis)
  • Subjects may enroll regardless of their serologic status for human immunodeficiency virus (HIV-1) and hepatitis C virus (HCV)
  • The subject requires a surgical, dental or other invasive procedure--either elective or emergency
  • The subject has a history of at least 150 exposure days for all other factor VIII products (as estimated by the study site investigator) prior to study entry
  • The subject has a life expectancy of at least 28 days from the day of surgery
  • The subject has been informed of the nature of the study, agreed to its provisions, and signed and dated the informed consent form approved by the appropriate IRB/IEC and Baxter BioScience

Exclusion criteria

  • The subject has a detectable inhibitor to factor VIII in the local hemostasis laboratory at the investigative site at the time of enrollment
  • The subject has a history of inhibitor to factor VIII > 1.0 BU. Note: If the subject has a history of an inhibitor titer > 1.0 BU at any time prior to enrollment but demonstrated expected clinical responses to conventional doses of factor VIII therapy, the subject may enroll
  • The subject has known hypersensitivity to Recombinate
  • The subject is currently participating in another investigational drug study, or has participated in any clinical trial involving an investigational drug within 30 days of study entry
  • The subject has clinical and/or laboratory evidence of abnormal hemostasis from causes other than hemophilia A (e.g., late-stage chronic liver disease, immune thrombocytopenic purpura, disseminated intravascular coagulation)
  • The subject is identified by the investigator as being unable or unwilling to cooperate with study procedures.
