The US Food and Drug Administration (FDA) has expanded the approved use of Vonvendi, a recombinant von Willebrand factor product.
Vonvendi is now approved for perioperative management of bleeding in adults (age 18 and older) with von Willebrand disease (VWD).
Vonvendi was previously FDA-approved for on-demand treatment and control of bleeding episodes in adults with VWD.
“Persons with von Willebrand disease face a heightened risk of bleeding during surgery and may require factor treatment before, during, or after surgery,” said Michael Tarantino, MD, of the Bleeding & Clotting Disorders Institute in Peoria, Illinois.
“For surgeries requiring repeated, frequent infusions with combined von Willebrand factor and factor VIII concentrates, an excessive rise in factor VIII levels may increase the risk of thromboembolic complications, such as blood clots. The expanded use for Vonvendi in surgical settings gives healthcare professionals flexibility in treating von Willebrand disease with an appropriate dose of von Willebrand factor, with or without recombinant factor VIII, based on each patient’s unique needs.”
The FDA’s approval of Vonvendi in surgical settings was based on results from a phase 3 trial. The study enrolled 15 adults with severe VWD who were undergoing elective surgical procedures (10 of them major procedures).
Patients received Vonvendi at 40 to 60 IU per kg of body weight 12 to 24 hours before surgery. Within 3 hours of surgery, each patient’s factor VIII level (FVIII:C) was assessed, with a target of 30 IU/dL for minor surgeries and 60 IU/dL for major surgeries.
Within an hour of surgery, patients received a dose of Vonvendi, with or without recombinant factor VIII, depending on the target FVIII:C levels at the 3-hour assessment.
The study’s primary endpoint was met. Vonvendi demonstrated overall hemostatic efficacy, as assessed 24 hours after the last perioperative infusion or the completion of the study visit, whichever occurred earlier.
Intra- and post-operative hemostasis was rated as “excellent” (as good as or better than expected) in 60% of patients and “good” (probably as good as expected) in 40% of patients.
One patient developed deep vein thrombosis 3 days after undergoing hip replacement surgery.
One patient tested positive for binding antibodies to von Willebrand factor. None of the patients developed binding antibodies against potential impurities such as rFurin, CHO-protein, or mouse IgG.
