Further study details as provided by Bio Products Laboratory:

Primary Outcome Measures:
  • A subjective overall assessment by the investigator of OPTIVATE® in the control of bleeding due to surgery throughout the whole study. [ Time Frame: Throughout the whole study ]

Estimated Enrollment: 25
Study Start Date: February 2007
Study Completion Date: September 2008
Intervention Details:
    Drug: Optivate
    Plasma-derived Factor VIII

Ages Eligible for Study:   12 Years and older   (Child, Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  1. Have given written informed consent.
  2. Be aged 12 years or older.
  3. Have VWD of known type.
  4. Be due to undergo surgery, in which the investigator believes a VWF concentrate will be required.
  5. Have a known lack of, poor response to, or contraindication to, DDAVP, or require a type of surgery in which a plasma-derived product is appropriate.
  6. Have a prothrombin time (PT) of not more than 3 seconds above the upper limit of the reference range.
  7. Female patients of child-bearing potential, with the exception of pregnant patients undergoing Caesarean surgery or other modes of delivery, including normal vaginal delivery, must have a negative result on a human chorionic gonadotropin-based pregnancy test. If a female patient is or becomes sexually active, she must practice contraception by using a method of proven reliability for the duration of the study.

Exclusion Criteria:

  1. Have a history of inhibitor development to VWF or FVIII or a positive result at screening (positive screen for VWF inhibitor; positive screen and a result of >0.5 BU for FVIII inhibitor). A result at screening is not mandatory if the patient is to undergo emergency surgery and the local laboratory is unable to perform the analyses.
  2. Patients with thrombocytopenia (platelets <50 x 109/L).
  3. Patients who have clinically significant renal disease (creatinine >200 µmol/L).
  4. Patients who have clinically significant liver disease (ALT levels greater than three times the upper limit of the reference range).
  5. Presence of any other major systemic illnesses which would compromise the outcome of the study in the opinion of the investigator.
  6. Known or suspected hypersensitivity to investigational medicinal product (IMP) or its excipients.
  7. Have a recent history of alcohol or drug abuse.
  8. Administration of a new chemical entity within the 4 months preceding enrolment.
  9. Participation in any other clinical study in which investigational or marketed drugs were employed in the 30 days preceding enrolment (screening visit) into this study, with the exception of the BPL clinical study Protocol 8VWF01.
  10. Female patients who are lactating.
  11. In the opinion of the investigator, the patient is unlikely to comply with the study protocol.
