A decision framework for treating chronic immune thrombocytopenia with thrombopoietin receptor agonists.

Aim: Eltrombopag and romiplostim are comparable second-line therapies in chronic immune thrombocytopenia. Treatment decisions are made in different contexts. A framework was created to outline decision pathways for physicians and payers. Materials & methods: The costs of drugs, administration, routine care, bleeding, other adverse events and mortality were included in the year-long calculation of total costs from a US private payer perspective. Treatment parameters and outcome data were obtained from relevant clinical trials. Results: The total cost per year, per patient of eltrombopag was US$51,000 versus US$76,000 for romiplostim. Drug costs and costs associated with bleeding-related events were the main drivers of cost difference. Conclusion: This framework facilitates decision-making in the management of chronic immune thrombocytopenia with eltrombopag and romiplostim.
