Summary

Low dose factor VIII prophylaxis is practiced around the world. Role of standard dose Emicizumab prophylaxis is well established. Emicizumab is an expensive drug. Standard dose Emicizumab prophylaxis is very expensive for hemophilia A patients and troublesome for government to ensure continuous supply. This study intends to compare low dose Factor VIII prophylaxis with low dose Emicizumab prophylaxis and compare whether low dose Emicizumab is as effective as low dose Factor VIII prophylaxis. So, it is possible to continue prophylaxis program in hemophilia A patients with a cost-effective way in our country without risking the patient health. Moreover, Emicizumab prophylaxis reduces the chance of developing inhibitor to Factor VIII and it is convenient for administration due to less frequent and subcutaneous administration. 20 severe hemophilia A patients will be selected randomly from interested patients for this study. 6 patients with inhibitor will be randomized in Low dose Emicizumab with Inhibitor group (I) and rest 14 will be randomized by block randomization in Low dose Emicizumab (without inhibitor-WI) and low dose Factor VIII group at 4:10 ratio. Initial loading dose will be given and the participants will be followed up for 6 months. At the end of the study Annualized bleeding rate (ABR), Annualized joint bleeding rate (AJBR), Annualized spontaneous bleeding rate (ASBR), APTT will be compared among the groups. Inhibitor to factor VIII will also be evaluated after six months in Factor VIII group.
