Could a clotting booster cut blood loss in ICU patients?
NCT ID NCT04555785
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether adding a drug called Wilate (a von Willebrand factor concentrate) to standard platelet transfusions can reduce bleeding and the need for more blood products in intensive care patients. About 120 adults who need platelets during or after surgery will be randomly assigned to get Wilate or a placebo. The goal is to see if this combination leads to less blood loss and better outcomes.
