Study summary

In this postmarketing study, the safety of Nonafact® (human coagulation factor IX) is evaluated in previous treated and untreated patients with severe, moderate or mild haemophilia B.

Read the detailed description

The clinical efficacy and safety of Nonafact® has been shown in two pre-authorisation studies. Marketing authorisation for the EU was granted 3 July 2001. The Post Marketing Study, which evaluates the clinical efficacy, immunogenicity and safety of Nonafact®, is set up according to CPMP/BPWG /198/95, rev. 1 (Final, London, 19 October 2000) 'Note for guidance on the clinical investigation of human plasma derived factor VIII and IX products'
