VWF Replacement Therapy for Von Willebrand Disease
(VIP Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial explores the best management of delivery for pregnant women with von Willebrand disease, a bleeding disorder, by using Wilate. This treatment helps maintain certain blood factor levels to reduce bleeding during and after childbirth. The main goal is to assess how effectively this approach prevents primary postpartum hemorrhage, or heavy bleeding after giving birth. Women with von Willebrand disease who struggle to maintain specific blood factor levels in late pregnancy might be suitable candidates for this study. As a Phase 2 trial, this research measures the treatment's effectiveness in an initial, smaller group, offering participants a chance to contribute to important medical advancements.
Do I need to stop my current medications for this trial?
The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your healthcare provider.
Is there any evidence suggesting that this trial's treatment is likely to be safe?
Research has shown that Wilate is safe and effective for treating bleeding in people with von Willebrand disease (VWD). In studies, both children and adults with VWD tolerated Wilate well. Importantly, no reports of blood clots or harmful antibodies, which are proteins that might attack the body’s own cells, were found. This suggests that Wilate generally does not cause serious side effects. The FDA reviewed the treatment and found no major safety concerns. Overall, evidence indicates that Wilate is a reliable option for managing bleeding in people with VWD.12345
Why are researchers excited about this trial?
Wilate is unique because it is a plasma-derived treatment specifically designed for von Willebrand disease (VWD), which aims to provide a more tailored approach to managing the condition during pregnancy. Unlike other treatments that may not offer the same precision, Wilate contains both von Willebrand factor and Factor VIII, crucial components for blood clotting, potentially offering better control over bleeding episodes. Researchers are excited because Wilate's dual-action mechanism could offer more effective and consistent management of VWD in pregnant women, potentially reducing complications for both the mother and the baby.
What evidence suggests that Wilate might be an effective treatment for von Willebrand disease during delivery?
Research has shown that Wilate effectively treats von Willebrand disease (VWD). Studies indicate that regular use of Wilate reduced bleeding episodes by 87% compared to treating them as they occurred. Approximately 84% of bleeding treatments with Wilate succeeded across all ages, with an 88% success rate in children and a 93% success rate overall. Wilate also reduces heavy menstrual bleeding in girls and women with VWD. It has proven safe and well-tolerated in both children and adults.
In this trial, participants will be categorized into two groups: "Correctors" and "Non-Correctors," based on their von Willebrand factor parameter levels.13678Who Is on the Research Team?

Treatment groups
Experimental Treatment
Patients with gestational week 34-38 von Willebrand factor activity, or von Willebrand factor ristocetin cofactor, or Factor VIII procoagulant activity less than 100 percent will be termed non-correctors. When laboratory monitoring can be performed, patients with an isolated von Willebrand factor collagen binding type 2 defect, von Willebrand factor collagen binding less than 100 percent can also be enrolled and determined as a non-corrector.
Patients with von Willebrand factor parameter levels greater than or equal to 100 percent self-corrected at gestational weeks 34-38 will be termed correctors.
