Long gone are the days when patients with haemophilia had to inevitably suffer the devastating consequences of this disease , which included life-threatening bleeding , pain , and disability . With the increasing adoption of coagulation factor replacement therapies , prophylaxis outcomes have substantially improved for patients , not only clinically but also in terms of quality of life ( QoL ). However , limitations to the long-term effectiveness and ability to prevent complications still persist with conventional anti-haemophilic coagulation factors . New coagulation factor replacement therapies with extended half lives that aim to provide individualised approaches and that are , at the same time , reducing treatment burden for patients , as well as being cost-effective , are now available . Indeed , the cornerstone of treatment remains preventing and controlling bleeding , and the current treatment paradigm is evolving , broadening its scope to include a more ‘ holistic ’ perspective of the disease , where joint care , pain control and QoL play a significant role .
In the past , the most common treatment regimens for haemophilia A involve the administration of factor VIII coagulation factor 3 – 4-times a week , 1 but a 12-month retrospective study in Europe showed that many patients still presented moderate-to-severe bleeding episodes , with median annualised bleeding rates ( ARBs ) ranging from 1.0 to 8.0 for patients on prophylaxis , and from 4.5 to 18.0 for those treated on demand . 2 Similar findings can be observed in patients with haemophilia A and B ( Figure 1 ). 2 The data demonstrate that there is still an unmet need with regards to offering protection against bleeding .
Extended half-life factors can help support prolonged haemostatic protection . Recombinant human coagulation factor VIII Fc fusion protein ( rFVIIIFc ) is an extended half-life FVIII molecule ( Elocta ® ; approved in 2015 for the treatment of figure 1
