•4. Be known or expected to require a concentrate for management of VWD.
•5. Must have had at least one spontaneous bleed in the last 12 months which required treatment with a FVIII and VWF concentrate.
•6. Have a known lack of, or poor response to DDAVP, or for whom DDAVP is contraindicated.
•7. Have a prothombin time (PT) of not more than 3 seconds above the upper limit of the reference range.
•8. At the Baseline Visit (Visit 1), patients must have had at least 5 days since their last infusion of replacement factor concentrate or DDAVP (see section 9.3.10 regarding the use of other concomitant medication).
