Description
Inclusion Criteria:
- History of at least 1 HAE attack per month or any history of laryngeal edema
In addition, this study was open to all subjects who:
- Completed participation in LEVP2005-1/B (NCT01005888) any time after the final prophylactic therapy in Part B
- Were enrolled but not randomized in LEVP2005-1/A (NCT00289211) after Part A was closed
- Were enrolled and randomized in LEVP2005-1/A after LEVP2005-1/B was closed to enrollment, any time after the 3-day telephone follow-up
Were excluded from LEVP2005-1 for any of the following reasons:
- Pregnancy or lactation
- Age less than 6 years
- Narcotic addiction
- Presence of anti-C1 inhibitor (C1INH) autoantibodies
Were not enrolled in LEVP2005-1 after enrollment in LEVP2005-1 was closed, under the following circumstances:
- Had a diagnosis of HAE: evidence of a low C4 level plus either a low C1INH antigenic level or a low C1INH functional level, or
- Had a known HAE-causing C1INH mutation, or
- Had a diagnosis of HAE based on a strong family history of HAE as determined by the principal investigator
Exclusion Criteria:
- History of allergic reaction to C1INH or other blood products
- Participated in any other investigational drug study within the past 30 days other than those sponsored by Lev Pharmaceuticals
- Received blood or a blood product in the past 60 days other than C1INH-nf

Other Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
|---|---|---|
|
Antigenic C1 Inhibitor (C1INH) Serum Levels
Time Frame: Pre-infusion to 1 hour post-infusion
|
Change from pre-infusion to 1 hour post-infusion in antigenic C1INH serum levels.
|
Pre-infusion to 1 hour post-infusion
|
|
Functional C1INH Serum Levels
Time Frame: Pre-infusion to 1 hour post-infusion
|
Change from pre-infusion to 1 hour post-infusion in functional C1INH serum levels.
Functional C1INH serum levels are expressed as a percent of total detectable C1INH (i.e., functional C1INH/total detectable C1INH).
|
Pre-infusion to 1 hour post-infusion
|
|
Complement C4 Serum Levels
Time Frame: Pre-infusion to 1 hour post-infusion
|
Change from pre-infusion to 1 hour post-infusion in complement C4 serum levels.
