FDA Approves Baxalta's von Willebrand Disease Drug

Dec 09, 2015

The U.S. Food and Drug Administration approved Vonvendi, von Willebrand factor (Recombinant), for use in adults 18 years of age and older who have von Willebrand disease (VWD). Vonvendi is the first FDA-approved recombinant von Willebrand factor, and is approved for the on-demand (as needed) treatment and control of bleeding episodes in adults diagnosed with VWD.

VWD is the most common inherited bleeding disorder, affecting approximately 1 percent of the U.S. population. Men and women are equally affected by VWD, which is caused by a deficiency or defect in von Willebrand factor, a protein that is critical for normal blood clotting.

The safety and efficacy of Vonvendi were evaluated in two clinical trials of 69 adult participants with VWD. These trials demonstrated that Vonvendi was safe and effective for the on-demand treatment and control of bleeding episodes from a variety of different sites in the body. No safety concerns were identified in the trials.
