Safety and Efficacy Study of CINRYZE for Prevention of Angioedema Attacks in Children Ages 6-11 With Hereditary Angioedema
A Phase 3, Multicenter, Randomized, Single-Blind, Dose-Ranging, Crossover Study to Evaluate the Safety and Efficacy of Intravenous Administration of CINRYZE® (C1 Esterase Inhibitor [Human]) for the Prevention of Angioedema Attacks in Children 6 to 11 Years of Age With Hereditary Angioedema

Brief Summary
Primary Objective - To assess the relative efficacy of two dose levels of CINRYZE (500 Units and 1000 Units) administered by intravenous (IV) injection every 3 or 4 days to prevent angioedema attacks in children 6 to 11 years of age with hereditary angioedema (HAE). Secondary Objectives - To assess the safety and tolerability, characterize the pharmacokinetics (PK) and pharmacodynamics (PD), and assess the immunogenicity of two dose levels of CINRYZE administered by IV injection in children 6 to 11 years of age with HAE.

Outcome Measures
Primary Outcomes (1)
Normalized Number of Angioedema Attacks Per Month in a Treatment Period
Angioedema attack was defined as the participant-reported indication of symptoms or signs such as swelling or pain at any location following a report of no swelling or pain on the previous day. Manifestations of an attack that progress from one site to another, prior to complete resolution, was considered a single attack. Attacks that began to regress and then worsened before complete resolution was also considered one attack. Attacks that began then appeared to resolve and then reappeared without a symptom-free calendar day reported after the appearance of resolution were considered 1 attack. Any events of swelling due to trauma or symmetrical nonpainful swelling of the lower extremities were not considered an angioedema attack. The number of attacks was normalized for the number of days participants participated in a given period and expressed as the monthly frequency.
From start of treatment up to 12 weeks during each treatment period
