Study of Vonicog Alfa for Severe Von Willebrand Disease in Children

This study is looking at how well a medicine called Vonicog Alfa (rVWF) works to prevent bleeding in children with severe Von Willebrand Disease (VWD). VWD is a condition where your blood doesn't clot properly. To join, you must be 17 years old or younger, have severe VWD, and have needed VWF concentrate treatment before. The study will treat participants with Vonicog Alfa for 12 months. Doctors will measure how many bleeding episodes you have during this time to see if the treatment is effective. The study is currently enrolling 24 participants.
