|Official Title:||LEVP2006-4 CHANGE 3 Trial (C1-Inhibitor in Hereditary Angioedema Nanofiltration Generation Evaluating Efficacy): Open-Label Use of C1INH-nf (Human) for the Prophylactic Treatment to Prevent HAE Attacks and as Treatment in Acute HAE Attacks|
|Study Start Date :||June 2006|
|Actual Primary Completion Date :||March 2009|
|Actual Study Completion Date :||March 2009|
Experimental: Open-label C1INH-nf
1,000 Units (U) of C1INH-nf administered intravenously (IV) every 3 to 7 days.
Biological: C1 esterase inhibitor [human] (C1INH-nf)
- Frequency of All HAE Attacks [ Time Frame: Duration of the study ]A hereditary angioedema (HAE) attack was defined as a discrete episode during which the subject progressed from no angioedema to symptoms of angioedema.
- 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.
- 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).
- 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.
