BACKGROUND: In a real-world analysis (RWA) conducted in the United States (US), median international units (IUs) of extended half-life (EHL) recombinant coagulation factor VIII (rFVIII) dispensed were 10% to 45% greater than standard half-life (SHL) rFVIII. The mean IUs of each rFVIII dispensed quarterly were obtained from two databases (N = 776). METHODS: A probabilistic model in a 1-year time horizon was used in order to analyze the cost comparison of SHL and EHL rFVIII products in Spain. In this analysis, mean IUs were those of the RWA, and frequency of use and prices for each rFVIII were obtained from sales estimates based on Spanish sources (IQVIA; €, 2019). RESULTS: Data showed an average annual savings per patient of €11,227 for SHL rFVIII versus EHL rFVIII products, with a savings probability of 75.5%. The results were stable in the sensitivity analyses. Not switching treatment from SHL to EHL rFVIII resulted in greater savings per patient (€53,078), with a savings probability of 99.9%. Considering the frequency of rFVIII dispensation in the US, annual savings per patient would increase to €16,350 in Spain, with a savings probability of 79.9%. CONCLUSIONS: According to this model, use of SHL rFVIII versus EHL rFVIII products could lead to savings for the Spanish National Health System.
