Despite representing a breakthrough in the treatment of immune-mediated rheumatic diseases, the direct costs of biotechnological therapies represent a burden to healthcare budgets worldwide. Furthermore, several studies demonstrated that socioeconomically constrained countries have poorer access to these therapies and this has consequences on the optimal management of rheumatic patients. Experience with small peptide biosimilars like filgrastim and epoetin confirmed significant cost savings but revealed variable market uptake. In this report, we summarize the available budget impact models and discuss possible determinants of the pharmacoeconomic performance of antirheumatic biosimilar drugs.
