  • Research summary

    The study is for children with severe von Willebrand disease (VWD), who have had treatment for this disease. These children have bleeding that happens suddenly and has no known cause, such as a nosebleed. They can also have bleeding that may happen because of a trauma, such as an accident. Most treatments for these children involve treating and slowing down bleeds that already happened. This is known as “on-demand” treatment.
    For this study, the study drug is used to stop a bleed before it happens (to prevent a bleed or the medical term is known as “prophylactic”). Instead of treating a bleed that happened, it is hoped that the study drug will help prevent bleeding before it starts.
    This study is going to look at how well the study drug (recombinant von Willebrand factor (rVWF), works to prevent and control bleeding.
