Abstract
Hemophilia A is an hereditary hemorragic disorder due to FVIII deficiency. In severe disease (FVIII< 1%), bleeding should be prevented with intravenous infusion of FVIII. One third of patients may have neutralizing antibodies that make treatment ineffective. For years, this group of patients with inhibitors
needed bypassing agents (rFVIIa or aPCC). Immunotolerance is the current recomendation to erradicate inhibitors in all patients.
Emicizumab is a biespecific antibody that mimics FVIIIa of subcutaneous use. It modifies patients´s phenotype and it has proven useful as prophylaxis in patients with and without inhibitors.
Due to a comfortable administration, stable pharmacokinetics, low immunogenicity and effective prevention of bleeding, it has a very important role in the present and future treatment for people with hemophilia A.
Due to adverse effects observed in association with aPCC in clinical trials, there are recommendations of different doses and schedules for the use of aPCC.
Use of emicizumab has to be monitored by Hemophilia Treatment Centers.
