22 March 2017 - Shire today announced that the United States FDA has granted fast track designation for recombinant ADAMTS13 (SHP655 - historically known as BAX930) for treatment of acute episodes of hereditary thrombotic thrombocytopenic purpura (hTTP) in patients with a constitutional deficiency of the von Willebrand factor-cleaving (VWF) protease ADAMTS13.
Hereditary thrombotic thrombocytopenic purpura is a life-threatening congenital disease caused by a deficiency in the enzyme ADAMTS13 which can cause clotting in the microvasculature with associated organ morbidities.
