Cost analysis of prophylaxis with activated prothrombin complex concentrate vs. on-demand therapy with activated factor VII in severe haemophilia A patients with inhibitors, in Spain.

Objective: A cost analysis model was developed to compare annual cost of prophylaxis with activated prothrombin complex concentrate (aPCC) vs. on-demand therapy with activated recombinant factor VII (rFVIIa) in severe haemophilia A patients with inhibitors for the Spanish National Health System (NHS).

Methods: Model inputs were drug cost for prophylaxis (aPCC) and for on-demand treatment (rFVIIa or aPCC); bleeding episodes management (excluding bypassing agent cost); surgical costs and disease management (excluding bleeding episodes).
