The safety and efficacy of Vonvendi was studied in 2 trials (n=69) that enrolled adults with VWD. Data showed treatment with Vonvendi was safe and effective for on-demand treatment and control of bleeding episodes. This was tested on various sites in the body. The study reported no safety concerns during the trials. Generalized pruritus was the most commonly observed adverse reaction. 

Vonvendi was granted Orphan Product designation for these indications.
