Brief Summary
To assess the efficacy of recombinant human C1-esterase inhibitor in the management of HAE prodrome for preventing the progression from prodrome to an acute angioedema attacks. Subjects will either receive Ruconest after the first 2 prodromes or during the last 2 prodromes. 5 clinic visits will occur within 24 hours of a prodrome. Subjects will complete prodrome severity and angioedema attack diaries

Outcome Measures
Primary Outcomes (1)
The primary endpoint was the difference in response rates in preventing HAE attacks between Conestat Alfa®-treated vs. untreated HAE prodrome events.
A mixed model for repeated measures was used to determine the statistical significance of Conestat Alfa®'s clinical efficacy for treating the HAE prodrome versus the acute attack.
