Design outcomes

Primary

MeasureTime frame
Annualized bleeding rates (ABRs) of treated bleeds estimated using nature and number of treated bleeds in the past 24 weeks prior to the emicizumab treatment, derived from participant’s files and treatment diaries from baseline until the end of the study (up to 5 years)

Secondary

MeasureTime frame
1. Percentage of participants with zero treated bleeds estimated using nature and number of treated bleeds in the past 24 weeks prior to the emicizumab treatment, derived from participant’s files and treatment diaries from baseline until the end of the study (up to 5 years) 2. ABRs of treated spontaneous bleeds, treated joint bleeds, treated target joint bleeds estimated using nature and number of treated bleeds in the past 24 weeks prior to the emicizumab treatment, derived from participant’s files and treatment diaries from baseline until the end of the study (up to 5 years) 3. Percentage of participants with zero treated spontaneous bleeds, treated joint bleeds, treated target joint bleeds estimated using nature and number of treated bleeds in the past 24 weeks prior to the emicizumab treatment, derived from participant’s files and treatment diaries from baseline until the end of the study (up to 5 years) 4. Number of doses and frequency of haemostatic medication besides emicizumab used to treat bleeding events or for other purposes, derived from participant’s files and treatment diaries from baseline until the end of the study (up to 5 years) 5. Percentage of participants with different dosing regimens of emicizumab, derived from participant’s files and treatment diaries from screening up to the end of the study (up to 5 years) 6. Number of invasive surgical procedures, derived from participant’s files and treatment diaries from day 1 up to the end of the study (up to 5 years) 7. Percentage of participants that used pain medication, derived from participant’s files and treatment diaries from day 1 up to end of study (up to 5 years) 8. Percentage of participants with occupational disability related to haemophilia A, derived from participant’s files and treatment diaries from day 1 up to the end of the study (up to 5 years) 9. Number of events of using health resources (number of contacts to the site, unscheduled visits at the site, number of emergency room (er)
