Baxter reports topline results from BAX 111 Phase 3 trial for treatment of von Willebrand disease


Baxter International Inc. (NYSE:BAX) today announced topline results from a Phase 3 clinical trial evaluating the safety, efficacy and pharmacokinetics (PK) of BAX 111. BAX 111 is a recombinant von Willebrand factor (rVWF) under investigation for the treatment of bleeding episodes in patients with von Willebrand disease, the most common type of inherited bleeding disorder.

The study of BAX 111, the first recombinant treatment in clinical development for this condition, met its primary efficacy endpoint, as all patients achieved pre-specified success in the on-demand treatment of bleeding events (100%, 22 of 22 patients who experienced bleeds in the trial).

”As the first recombinant, stand-alone treatment in development, BAX 111 has the potential to offer people with von Willebrand disease a new therapeutic option that may allow for greater precision and flexibility in managing the disease,” said Bruce Ewenstein, M.D., Ph.D., vice president of clinical affairs, in Baxter BioScience. ”With these findings, we have taken another significant step forward as we continue to expand on our increasingly broad pipeline of potential treatments to improve outcomes for patients with a range of bleeding disorders.”

The Phase 3 multicenter, open-label clinical trial assessed the safety, efficacy and pharmacokinetics of BAX 111 administered together with ADVATE or as a stand-alone therapeutic agent in the on-demand treatment of 37 patients with severe von Willebrand disease at trial sites in the United States, Europe, Australia, Japan, Russia and India. The primary endpoint was the number of patients experiencing successful treatment for bleeding episodes. Secondary endpoints included additional efficacy and safety measures, pharmacokinetics and health-related quality of life (HRQoL).
