Study Description
Brief Summary:
This is a prospective, international, multi-center, non-randomized, single arm, open-label, postmarketing study to investigate the formation of inhibitory anti-C1-INH antibodies in HAE subjects treated intravenously with Berinert. Individual treatment duration per subject is 9 months, irrespective of the number of treated attacks. All subjects will receive 20 IU Berinert/kg body weight per attack.

Condition or disease Intervention/treatment Phase
Hereditary Angioedema Types I and II Biological: Berinert, lyophilizate for IV application containing 500 IU C1-INH to be reconstituted with 10 mL water for injection Phase 4

Arms and Interventions

Arm Intervention/treatment
Experimental: Berinert Biological: Berinert, lyophilizate for IV application containing 500 IU C1-INH to be reconstituted with 10 mL water for injection
Individual treatment duration per subject is 9 months, irrespective of the number of treated attacks. Each attack that occurs in this time frame will be treated with 20 IU Berinert/kg body weight.


Outcome Measures

Primary Outcome Measures :
  1. Number of Subjects With Inhibitory Anti-C1-esterase-inhibitor Antibodies [ Time Frame: Baseline to approximately 9 months ]
    Subjects with no positive baseline result and at least one positive post-baseline result for inhibitory anti-C1-INH antibodies.


Secondary Outcome Measures :
  1. Number of Subjects With Any (Inhibitory or Non-inhibitory) Anti-C1-esterase-inhibitor Antibodies [ Time Frame: Baseline to approximately 9 months ]
    Subjects with at least one positive result for inhibitory or non-inhibitory anti-C1-INH antibodies.
