What is Vonvendi, and what clinical trials has it been studied in?
Vonvendi (von Willebrand factor concentrate) is used for patients with von Willebrand disease (vWD). The key clinical evidence reported for Vonvendi comes from trials designed to evaluate how well it raises/maintains von Willebrand factor (vWF) activity and factor VIII activity, and to assess bleeding control and safety in real-world bleeding and surgery settings.
What outcomes are usually measured in Vonvendi trials?
Trials of Vonvendi typically focus on hematologic and bleeding endpoints, including:
- vWF activity and factor VIII activity levels after dosing
- treatment response during bleeding episodes
- safety outcomes such as adverse events and inhibitor-related findings (inhibitors are a major concern in some vWD therapies)
How long are the dosing and follow-up periods in Vonvendi studies?
Study duration varies by protocol. Clinical trials generally include:
- short-term dosing and monitoring around a bleeding event or procedure
- follow-up to assess whether factor levels remain controlled and to capture adverse events
Who takes part in Vonvendi clinical studies?
Enrollment typically includes patients diagnosed with von Willebrand disease who need treatment for:
- active bleeding
- perioperative management (before/during/after surgery), depending on the study design and indication being tested
Are there any important safety issues patients ask about in Vonvendi trials?
Patients and clinicians commonly look for:
- infusion-related reactions
- thrombosis risk (especially because factor VIII levels can rise)
- development of inhibitors/antibodies to vWF (less common but clinically important)
Where can I read trial-by-trial details (protocols, endpoints, publications)?

What specific Vonvendi trial are you looking for?
“Vonvendi clinical trial” can refer to different study types (bleeding management, surgery, pharmacokinetics, safety follow-up). If you share any of the following, I can narrow to the exact trial and summarize its design and results:
- the condition/setting (acute bleeding vs surgery)
- the sponsor or study ID (e.g., NCT number)
- the year or publication you saw referenced
