title: Kiovig for primary immunodeficiency: reduced infusion and decreased costs per infusion.
abstract: Kiovig is a ready-to-use 10% liquid immunoglobulin preparation that is medically indicated for the treatment of primary immunodeficiency. This study aims to conduct an economic evaluation which compares the intravenous immunoglobulin (IVIg) preparations Kiovig, Multigam, and Sandoglobulin from the Belgian societal perspective. As three prospective studies have observed no difference in outcomes, a cost-minimization analysis is considered appropriate to evaluate differences in treatment costs that can arise from IVIgs. A decision-analytic model simulated treatment costs attributed to one infusion. Resource use data were derived from a Dutch costing study. Cost items included immunoglobulin costs, pharmacy administration and nursing costs, mini-forfait for hospital infusion, costs of adverse events, and lost productivity with 2009 as base year. Cost data were identified from published sources and Belgian hospital administrators. A probabilistic sensitivity analysis explored the impact of parameter uncertainty on cost results. Costs per infusion cycle in adult primary immunodeficiency patients were €1,046 (95% confidence interval: €1,006-1,093) with Kiovig; €1,102 (€1,064-1,147) with Multigam; and €1,147 (€1,108-1,193) with Sandoglobulin. The average cost savings per infusion with Kiovig as compared to Multigam and Sandoglobulin amounted to €56 and €101 per infusion. In conclusion, treatment costs with Kiovig were shown to be lower as compared to other IVIgs in Belgium. Reduced costs per infusion were attributed to lower costs associated with treating adverse events and the opportunity cost of nursing time and time off work for working adults.
