Turoctocog alfa pegol (N8-GP) provides the benefit of extending the duration of protection from bleeding and reducing the number of injections, which is expected to impact HRQoL and treatment satisfaction (TS). Aim: To investigate the HRQoL and TS of patients with severe hemophilia A from two phase III trials evaluating the safety and efficacy of N8-GP. Methods: HRQoL was assessed using the Haemo-QoL (reported by children and their parents) and Haem-A-QoL (reported by adults). TS was assessed using Hemo-Sat. Domain and total scores for all questionnaires ranged from 0 to 100, with lower scores indicating a better HRQoL or TS. A negative change in score indicates an improvement in HRQoL/TS. Results: Mean changes in HRQoL scores were reported for 14 children aged 4–7 years, 21 children aged 8–11 years, 10 adolescents aged 13–16 years, and 163 adults (17 years and above). Mean changes in children/adolescents-reported Haemo-QoL total score were -14.0 for ages 4–7 years, -3.6 for ages 8–11 years, and -0.1 for ages 13–16 years. Mean changes in parent-reported Haemo-QoL total scores were -11.5 for 4–7 years, -8.6 for ages 8–11 years, and -4.0 for 13–16 years. Adults’ mean change in Haem-A-QoL total score was -3.1 for those receiving on-demand treatment and -2.3 for those receiving prophylaxis treatment. High levels of TS with N8-GP were reported by parents of children/adolescents and the adults at the end of the trial. Conclusion: While most patients reported a relatively good baseline HRQoL when entering the respective trials, the HRQoL of patients was either maintained or further improved when treated with N8-GP. Adults and parents of children and adolescents reported a high level of treatment satisfaction with N8-GP.
