VONVENDI® [von Willebrand factor (Recombinant)] is approved to reduce the frequency of bleeding episodes in patients with severe Type 3 VWD receiving on-demand therapy.1

Prophylaxis clinical trial description

  • A prospective, single-arm, open-label, international multicenter study evaluated the efficacy and safety of VONVENDI in 10 adult patients with severe Type 3 VWD who were previously treated on-demand.1
    • These participants had ≥ 3 bleeding episodes (excluding menorrhagia) that required VWF treatment in the 12 months prior to enrolling in the study.2
  • Patients began treatment at 50 ± 10 IU/kg per infusion twice weekly.1
    • Most patients (9/10) received twice-weekly dosing with VONVENDI and had a median maximum dose of 55.9 IU/kg. One patient required dose adjustments for management of breakthrough bleeding.1

VONVENDI prophylaxis may provide bleed protection for severe Type 3 VWD1

In a clinical trial, routine prophylaxis with VONVENDI helped reduce the number of bleeds for adults with severe Type 3 VWD who were previously treated on-demand (N=10).1

Summary of adverse reactions in patients with VWD from the prophylaxis clinical trial1‡

This chart shows the adverse reactions from the completed prophylaxis clinical study (N=22).

These trials were conducted using VONVENDI (recombinant VWF) and, when necessary, a recombinant factor VIII.

Dosing for prophylaxis

For initiation of prophylactic treatment, administer 40 to 60 IU of VONVENDI per kg of body weight twice weekly. Adjust prophylaxis dose up to 60 IU/kg twice weekly if breakthrough bleeding occurs in joints or if severe bleeding occurs.1
