New blood thinner tested for rare clotting disorder
NCT ID NCT00861692
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at how well the drug argatroban works in 20 adults with a condition called heparin-induced thrombocytopenia Type II, where the blood thinner heparin causes low platelets and raises clot risk. Participants received argatroban to prevent new or worsening blood clots. Researchers tracked deaths, new clots, amputations, and bleeding to understand the drug's safety and effectiveness.
