Brief Summary:

The purpose of this study in pediatric participants (<18 years of age) with severe hereditary von Willebrand disease (VWD) is:

  1. To assess the efficacy, safety, and tolerability of recombinant von Willebrand Factor (rVWF), with or without ADVATE, in the treatment and control of nonsurgical bleeding events
  2. To assess the efficacy and safety of rVWF with ADVATE during elective or emergency surgery
  3. To determine the pharmacokinetic (PK) profile of rVWF

Condition or disease Intervention/treatment Phase
Von Willebrand Disease Biological: von Willebrand factor (Recombinant) Biological: Antihemophilic Factor (Recombinant) Phase 3

Detailed Description:

18 JUN 2020: The temporary enrollment stop of new patients into this study due to the COVID-10 pandemic has been lifted in one or more countries/sites, and the study is now again enrolling new patients. However, some countries/sites may still have paused the enrollment of new patients due to the pandemic.

23 APRIL 2020: Enrollment of new patients into this study has been paused due to the COVID-19 situation. The duration of this pause is dependent on the leveling and control of the COVID-19 pandemic.
