Summary Background and objective: Cost control is becoming an increasingly important consideration for clinicians when planning how to provide the best treatment for anaemic cancer patients. Administration of erythropoiesis stimulating agents (epoetin alpha, epoetin beta and darbepoetin alpha) has become the standard of care for treatment of anaemia in cancer patients. However, only limited information is available on the economic comparability of epoetin alpha, epoetin beta and darbepoetin alpha, and thus this study was conducted to compare cost per patient of each of these agents for anaemic cancer patients. Methods: All prescriptions of the agents over 1 year were analysed by two Austrian regional public health insurance associations and cost per patient for each agent was calculated from invoicing data. Data from the two regions were combined to obtain total mean drug costs per patient per year. Results and discussion: Analyses showed significantly lower costs for epoetin alpha (€2743·27) than for darbepoetin alpha (€3627·98) or epoetin beta (€3292·28): epoetin alpha vs. darbepoetin alpha ( P < 0·0001); epoetin beta vs. darbepoetin alpha ( P = 0·0001); epoetin alpha vs. epoetin beta ( P = 0·0009). As costs of the three agents in Austria are identical for therapeutically equivalent doses, the higher cost of darbepoetin alpha was believed to be due mainly to longer treatment duration to target haemoglobin level. Conclusion: The finding of a cost difference favouring epoetin alpha over darbepoetin alpha suggests the need for prospective randomized studies comparing efficacy and cost effectiveness of all three agents to obtain more definitive data.
