PK80- Ratio of Intra-participant PK of VWF:RCo, VWF:Ag and VWF:CB at Baseline and After 6 Months

Area under the plasma concentration curve (AUC) from time 0 to infinity per dose (AUC0-∞/dose) for von Willebrand Factor Ristocetin cofactor (VWF:RCo), von Willebrand Factor Antigen (VWF:Ag) and von Willebrand Factor Collagen Binding (VWF:CB). Each parameter was compared between the two PK assessments after infusion of 80 IU/kg recombinant von Willebrand Factor:von Willebrand Factor Ristocetin cofactor (VWF:RCo rVWF) \[rVWF\] for participants in the PK80 arm (participants from Arm 3 with PK80 data only). PK assessment conducted at first infusion of 80 IU/kg rWVF \[PK1\] and the second infusion of 80 IU/kg rVWF after participants were treated on demand for bleeding episodes for at least 6 months since their first infusion of study product \[PK2\]. 13 participants had data available for this endpoint i.e. data for PK1 and PK2.

Time frame: PK evaluations at pre-infusion, then at 15, 30 and 60 mins, and 3, 6, 12, 24, 30, 48, 72 and 96 hrs post-infusion. PK evaluation timeframe for 28 ± 3 days after first infusion of study product which includes PK evaluation for both infusions and washout.
