Brief Summary:
International, post-authorisation non-interventional study to evaluate real-life effectiveness, safety and utilisation patterns of Octapharma's FVIII concentrates Nuwiq, Octanate, and Wilate in previously untreated and minimally treated severe haemophilia A patients in routine clinical practice.

Condition or disease
Haemophilia A

Detailed Description:
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.

All patients receiving Nuwiq (recombinant FVIII)
All patients receiving Octanate (plasma derived FVIII)
All patients receiving Wilate (plasma derived FVIII/von Willebrand factor [VWF])

Primary Outcome Measures :
  1. Annualised rate of breakthrough bleeds to assess efficacy in prophylactic treatment [ Time Frame: 100 exposure days ]
    Annualised rate of all bleeding events (BEs), including all spontaneous, traumatic and joint BEs

  2. Incidence of Adverse Drug Reactions (ADRs) [ Time Frame: 100 exposure days ]
    Adverse drug reactions (ADRs) including hypersensitivity reactions will be recorded in by patients in treatment diaries, which will be reviewed at each Follow-up Visit.

Secondary Outcome Measures :
  1. Dosage of FVIII concentrates [ Time Frame: 100 exposure days ]
    For each individual FVIII injection the dose will be recorded.

  2. Overall assessment of the effectiveness of surgical prophylaxis by the treating physicians [ Time Frame: 100 exposure days ]
    At the end of the postoperative period, treating physicians will assess the effectiveness of surgical prophylaxis using a scale including the four items: 'excellent,' 'good,' moderate,' and 'none'.
