Summary
Brief summary
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 1½
years.
