Immune thrombocytopenic purpura (ITP) is an autoimmune disorder that leads to a decrease in platelet production, thus increasing the risk of bleeding. Current therapies for ITP can be broadly divided into immunomodulators and thrombopoietin receptor agonists (TPO–RAs). Systemic glucocorticoids and TPO–RAs are the cornerstones of clinical management; however, biologics such as rituximab provide additional options for refractory patients. In 2018, two novel therapies for chronic ITP—Rigel Pharmaceuticals’ Tavalisse (fostamatinib), an oral Syk inhibitor; and Sobi’s Doptelet (avatrombopag), a second-generation TPO–RA—launched in the United States. This report offers insights from real-world claims data into prescribing trends in ITP to help new players better understand current treatment practices in ITP that may help define the market niche for their emerging product.
