VONVENDI® and surgery

In a clinical trial, 100% of adult VWD patients had their surgical bleeding successfully managed with VONVENDI.

Study description

VONVENDI, given with or without additional recombinant factor VIII (rFVIII), was studied in a clinical trial to test how it would work to prevent excessive bleeding during and after surgery. The clinical trial included 15 adult patients who underwent a total of 15 surgeries.

In this trial, patients received VONVENDI before and after surgery as determined by the care team. rFVIII was given as needed.* Investigators rated bleed control on a 4-point scale where “Excellent”=1, “Good”=2, “Moderate”=3, and “None”=4. A rating of “Excellent” or “Good” was required to declare the outcome a success.

100% of adult surgeries (15 of 15) were managed successfully, with 9/15 rated as “Excellent” and 6/15 rated as “Good”
The amount of blood loss experienced by people in the study was comparable to that of a person without VWD
Number 1.
Most people (10/15) needed only VONVENDI to manage their surgical bleeding

Study safety

Six patients reported 12 adverse events after starting treatment. One case of a blood clot in a deep vein, also known as deep vein thrombosis (DVT), was considered possibly related to VONVENDI.

*Your doctor will decide if you may use VONVENDI by itself, or if you also require rFVIII along with VONVENDI, based on your clinical situation.

Bleed control for a range of procedures

VONVENDI can be used to prevent excessive bleeding during and after major and minor surgeries and procedures in various locations, including:

Mouth
(eg, dental extraction)
Nose/throat
(eg, nasopharyngoscopy)
Female reproductive system
(eg, cyst removal)
GI tract
(eg, colonoscopy)
Joint
(eg, joint replacement)

Leslie’s Story

Diagnosed 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."
