A Study Following People With Haemophilia A and B, With or Without Inhibitors, When on Usual Treatment (Explorer™6)
Completed
Conditions studied: Haemophilia A, Haemophilia A With Inhibitors, Haemophilia B, Haemophilia B With Inhibitors
In brief
This study will collect data on bleeds and data related to quality of life in people with severe congenital (a disease existing from birth) haemophilia A and B, with or without inhibitors. The aim for the study is to look at the number of bleeds when on usual treatment for haemophilia. Participants will be asked to keep an electronic diary to track the number of bleeds and the treatment of their bleeds. Participants will be asked to wear an activity tracker on their wrist to capture their level of activity every day for up to 12 weeks. While taking part in this study, participants will keep getting their usual treatment as given to them by their doctor. All study visits at the clinic are done in the same way as the participants are used to. In the time between the participants' visits to the clinic, the study staff at the clinic may call or email the participant. The study will last for about 2½ years.
