The multicenter prospective non-interventional AHEAD study was initiated to obtain
long-term outcome data on joint health, HR-QoL, haemophilia-related co-morbidities,
and the effectiveness and safety of ADVATE (recombinant anti-hemophilic factor VIII,
plasma-free method [octocog alfa]) in routine clinical practice.
The German AHEAD study arm aims to enroll up to 500 patients in up to 35 haemo - philia
treatment centers (HTCs); patient recruitment started in June 2010. The study arm
conducted in other European countries is expected to enroll 350 patients from more
than 50 HTCs; recruitment started in June 2011. In both study arms, recruitment will
continue through the end of 2015, and each enrolled patient will be followed for a
total of four years.
