Acquired thrombotic thrombocytopenic purpura is a rare blood disorder with a high early mortality rate, if untreated. Standard of care plasma exchange and glucocorticoids have dramatically improved survival. However, additional advancements are necessary to further decrease mortality. Caplacizumab-yhdp (Cablivi®) is the first Food and Drug Administration-approved treatment indicated for adult patients with acquired thrombotic thrombocytopenic purpura, in combination with plasma exchange and immunosuppressive therapy. However, there are considerable risks associated with the use of caplacizumab and they must be weighed against the benefits of the medication.
