The purpose of the study is to evaluate the effect of prophylactic treatment on the number of joint bleeds and quality of life in severe hemophilia A subjects compared to on-demand treatment in a one-group two-treatment schedule design.

In addition, the effect of prophylactic treatment on the joint function, the number of all bleeds, and on the quality of life compared to on-demand treatment and health-economic data will be assessed.

Further study details as provided by Bayer:

Primary Outcome Measures:
  • Number of Joint Bleeds [ Time Frame: Months 1-6 (on-demand treatment) and 8-13 (prophylactic treatment) ]
    Number of joint bleeds during Months 8-13 compared to number of joint bleeds during Months 1-6

Secondary Outcome Measures:
  • Number of All Bleeds [ Time Frame: Months 1-6 (on-demand treatment) and 8-13 (prophylactic treatment) ]
    Mean number of all bleeds during Months 8-13 (prophylactic) compared to mean number of all bleeds during Months 1-6 (on-demand)

  • Physical Assessment Compared to On-demand Treatment as Determined by the Gilbert Score [ Time Frame: Month 13 (end of prophylactic treatment) and Month 6 (end of on-demand treatment) ]
    Total score with a range of 0-100, evaluating ankle, knee and elbow, 0 indicates normal function, higher values indicate joint damage

  • Quality of Life Compared to On-demand Treatment as Measured by the Haemo-QoL A Questionnaire [ Time Frame: Month 13 (end of prophylactic treatment) and Month 6 (end of on-demand treatment) ]
    Total transformed score with a range of 0-100, higher values indicate better outcome. 41 items in 6 domains: physical functioning; role functioning; worry; consequences; positive affect; treatment concern.

Enrollment: 20
