VONVENDI® was tested in a clinical trial for on-demand treatment.1
VONVENDI, given with and without additional recombinant FVIII (rFVIII), was studied in 22 adult patients with different types of severe von Willebrand disease (VWD) to test how it would work to control a total of 192 bleeds. The first dose of VONVENDI was given with rFVIII; if further doses were necessary, rFVIII was given only when needed. Investigators rated bleed resolution according to a scale of "Excellent=1," "Good=2," "Moderate=3," or "None=4." Treatment success was defined as a mean efficacy rating score of less than 2.5 for all bleeding episodes.1,2
100% of people (18/18) had their bleeds successfully treated1b
96.9% of 192 bleeds were rated as "Excellent," with the remaining 3.1% rated as "Good"1
81.8% of 192 bleeds were cleared up after just one infusion (ranges 1-4)1a
aYour doctor will decide if you may use VONVENDI by itself, or if you also require rFVIII along with VONVENDI, based on your clinical situation.1
bThis analysis excluded 4 of a total of 22 patients who were treated with VONVENDI in the trial.1
In the clinical study, an average of one infusion of VONVENDI (with or without rFVIII) (ranges 1-4) treated mild-to-moderate bleeding episodes. People who experienced a major bleed required an average of two doses (range 1-3 doses). In two cases, as many as three doses were needed to control bleeding.1
VONVENDI can be used on-demand by adults with VWD to control major
and minor bleeds in all locations, such as1:

Leslie's storyDiagnosed with VWD in 2003
"Once I was trained on how to do my own infusion, I infused on the eve of the surgery and again right before. I also infused after surgery—this was my normal for any surgery. I was amazed at how well this treatment worked for me."

"Although I've faced many battles since I was diagnosed, the amount of support I had from all the other patients fighting the same battle gave me strength."
