- All sexes
- No healthy volunteers
- Child, Adult, Older adult
Who may be able to join
- Have given written informed consent.
- Be aged 12 years or older.
- Have VWD of known type.
- Be due to undergo surgery, in which the investigator believes a VWF concentrate will be required.
- 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.
- Have a prothrombin time (PT) of not more than 3 seconds above the upper limit of the reference range.
- 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.
Who cannot join
- 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.
- Patients with thrombocytopenia (platelets <50 x 109/L).
- Patients who have clinically significant renal disease (creatinine >200 µmol/L).
- Patients who have clinically significant liver disease (ALT levels greater than three times the upper limit of the reference range).
- Presence of any other major systemic illnesses which would compromise the outcome of the study in the opinion of the investigator.
- Known or suspected hypersensitivity to investigational medicinal product (IMP) or its excipients.

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study was stopped early (reason given: Due to slow recruitment and a delay in reaching the recruitment target.). Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
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). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Mar 2010.
