Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Primary Objective:

To evaluate the efficacy of recombinant human C1 inhibitor (rhC1INH) in the prophylaxis of angioedema attacks in patients with HAE

Secondary Objective:

To evaluate the safety and immunogenicity of recombinant human C1 inhibitor (rhC1INH) in the prophylaxis of angioedema attacks in patients with HAE

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Study Design:

This is a multi-center, randomized, double-blind, placebo-controlled, 3-period crossover study of rhC1INH in prophylaxis of angioedema attacks in patients with HAE.

Medical screening (clinical and laboratory parameters) will be performed and patient medical history specific to HAE attacks will be collected to assess eligibility. Each patient will receive three 4 week periods of treatment twice weekly.
