FDA Expands Vonvendi Approval to Include Pediatric von Willebrand Disease Patients
- The FDA has expanded approval of recombinant von Willebrand factor (Vonvendi) to include pediatric patients with von Willebrand disease for acute bleeding treatment and surgical procedures.
- This marks the first non-plasma-derived VWF therapy available for children in the United States, offering more consistent pharmacokinetics and eliminating plasma-based therapy risks.
- The approval also extends routine prophylactic use to adults with all types of VWD, previously limited to only severe Type 3 cases.
- Clinical data showed most non-surgical bleeds in pediatric patients were effectively managed with a single infusion, with a half-life of 14.3 hours in children.
