Immune Thrombocytopenic Purpura | Treatment Algorithms: Claims Data Analysis | US | 2023

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.

Questions answered

• What patient shares do key therapies and brands garner by line of therapy in newly diagnosed ITP patients? What are the quarterly trends in prescribing among recently treated and newly diagnosed ITP patients?
• How have TPO-RAs been integrated into the treatment algorithm, and what are their sources of business?
• What percentage of ITP patients receive drug therapy within one year of diagnosis, and how quickly? What percentage of patients progress to later lines of therapy within one year of diagnosis?
• What percentage of ITP patients are treated with monotherapy vs. combination therapy? What are the most commonly used combinations?
• What are the product-level compliance and persistency rates among drug-treated patients?
