Reported results are baseline (month 0) and change from baseline (at month 6) of end of disease and age specific HRQOL. HRQOL was collected through use of the patient reported outcome (PRO) instruments, HAEMO-QOL (for children (8-12 years)/adolescents (13-16 years)) and HAEM-A-QOL (for adults (>=17 years)). HAEMO-QOL assessment included questions on physical health, feeling, view of yourself, family, friends, perceived support, other persons, sports and school, dealing with haemophilia, treatment, future, and relationships. HAEM-A-QOL assessment included questions on physical health, feeling, view of yourself, sports and leisure, work and school, dealing with haemophilia, treatment, future, family planning, and partnership and sexuality. Scores range for each question was 0-100, with a lower score indicating better quality of life related to haemophilia. Observed mean of the means of all the questions for HAEMO-QOL and HAEM-A-QOL, respectively are presented.

Blood samples for the evaluation of incremental recovery of FVIII were taken during a period of 48 hours post-dosing for participants 12 years and older and 24 hours post-dosing for participants below the age of 12 years. The incremental recovery was calculated as (FVIII: coagulant (C) activity measured in plasma 30 minutes after dosing - FVIII:C activity measured in plasma immediately before dosing)/(dose injected at time 0 minute), where the dose was expressed as IU FVIII product per kg body weight. The results are based on the chromogenic assay.

Blood samples for the evaluation of AUC0-inf were taken during a period of 48 hours post-dosing for participants 12 years and older and 24 hours post-dosing for participants below the age of 12 years. AUC0-inf was defined as the area under the concentration versus time from time curve zero to infinity. The results are based on the chromogenic assay.
