Two children with haemophilia B were managed with the use of a personalised/tailored dosing schedule of factor IX Fc fusion protein. Compared with the standard half-life factor IX, prophylaxis with factor IX Fc fusion protein was cost-effective, with much less injections, better bleeding control, improved tolerability or no inhibitor development.
