Octapharma's FVIII concentrates have been tested in clinical trials and registered for treatment of haemophilia A; however, as haemophilia A is a rare disease, the numbers of patients treated in studies so far are limited. For previously untreated patients (PUPs), who are typically young children, and for minimally treated patients (MTPs), who have been exposed to only minimal FVIII dosages, there is a general interest to increase the body of data on treatment effectiveness and safety, particularly related to inhibitor development. Also, specifically for PUPs, treatment algorithms are not standardized, e.g. with respect to utilisation, dosage, frequency or optimal start age of FVIII prophylaxis. Real world evidence derived from a non-interventional study (NIS) can describe product utilisation and demonstrate value over a product's life cycle and facilitate benefit-risk assessments. The purpose of this study is thus to evaluate product utilisation, effectiveness and safety, including inhibitor development information, in severe haemophilia A PUPs and MTPs, who have been prescribed Octapharma's FVIII concentrates.
