A Study Following Males With Haemophilia B on Prophylaxis With Refixia/REBINYN

Conditions
Haemophilia B
Interventions
Registration Number
NCT03745924
Lead Sponsor
Novo Nordisk A/S
Brief Summary

This study will collect information on side effects and how well Refixia/REBINYN works during long-term treatment (prophylaxis) in males with haemophilia B. While taking part in this study, participants will receive the same treatment as given to them by their study doctor. All visits at the clinic are done in the same way as the participants are used to. During visits at the clinic, participants might be asked for some relevant tests if considered useful by their study doctor. During the visits, the participants study doctor might ask if the participants had any side effects since their last study visit. The participants will be asked to note down the number of bleeds and the treatment of their bleeds as well as their regular prophylaxis. During the visits to the clinic, the participants will be asked to answer some questionnaires about their quality of life and their ability to be physically active. The participant's participation in the study will last for 4-9 years, depending on when they join the study. Participants are free to leave the study at any time and for any reason. This will not affect their current and future medical care.

Count of events

Secondary Outcome Measures
NameTimeMethod
Number of bleeding episodes during long-term routine use of N9-GP (prophylaxis) as assessed by annualised bleeding rate (ABR)From start of study period (week 0) to up to 9 years

Count of episodes

Haemostatic effect of N9-GP when used for treatment of bleeding episodesFrom start of study period (week 0) to up to 9 years

Count of bleeding episodes. Haemostatic effect is assessed as success/failure based on a four-point scale for haemostatic response (excellent, good, moderate and poor) by counting excellent and good as success and moderate and poor as failure
