Primary outcomePrimary: HAE Attacks/Week — 0.9; 0.4 attacks/week
Summary
Hereditary angioedema ("HAE") is a disease characterized by recurrent tissue swelling affecting various body locations. Recent literature shows that patients with frequent attacks may benefit from long-term prophylaxis. This study aims to evaluate the safety and prophylactic effect of weekly administrations of 50 IU/kg recombinant C1 Inhibitor ("rhC1INH").
