Potential for Recombinant ADAMTS13 as an Effective Therapy

the life-threatening disease thrombotic thrombocytopenic purpura (TTP). The vast majority of patients have acquired TTP, where circulating anti-ADAMTS13 autoantibodies are causative for the decreased ADAMTS13 activity. Current treatment consists of plasma exchange, but improved therapies are highly warranted.

ITP stands for Immune Thrombocytopenia (also known as Immune Thrombocytopenic Purpura, and sometimes referred to by its outdated name Idiopathic Thrombocytopenic Purpura).

Thrombotic thrombocytopenic purpura is a hematologic emer-gency. Untreated, it is associated with mortality as high as 90%; with plasma exchange, mortality can be reduced to 20%.4 Once TTP is suspected, plasma exchange should be instituted promptly. Plasma exchange is a procedure in which plasma from the patient
