This study is monitoring the safety and effectiveness of a drug called vonicog alfa (rVWF) in children under 18 with Von Willebrand disease, a condition that causes excessive bleeding. Doctors will give the drug as usual treatment for bleeding episodes or around surgery, and researchers will track any side effects and how well it works for one year. The goal is to gather real-world information on how this drug performs in pediatric patients in Japan.
