Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Written informed consent or, if less than 18 years of age written assent (where possible) and their parent/guardian's written informed consent.
  • Severe haemophilia A (< 1%# FVIII:C).
  • Previously Treated Patients (PTPs) with > 150 exposure days on prior Factor VIII therapy (of which at least the last 50 EDs or 2 years treatment can be confirmed by way of subject records).
  • Immunocompetent with CD4 count > 200 / µl.
  • HIV negative or a viral load < 200 particles / µl.

    • subjects suffering from severe haemophilia A (<2%) may be enrolled, but only after approval by BPL. Subjects with a Factor VIII of <2% may not constitute more than 50% of the total patient population. A separate statistical evaluation will be conducted for the <1% and <2% populations.

Exclusion Criteria:

  • • History of inhibitor development to FVIII or a positive result on the Nijmegen Bethesda at screening (quantitative result of > 0.6 BU) prior to the administration of Optivate®.

    • Known or suspected hypersensitivity to the investigational medicinal product or its excipients.
    • Clinically significant liver disease, renal disease, or coagulopathy other than haemophilia A.
    • History of unreliability or non cooperation (including not being able to complete the study diary).
    • Participating in, or have taken part in another trial within the last 30 days.
