Brief Summary:
The study objective was to evaluate the safety and efficacy of prophylactic use of C1INH-nf for the prevention of acute HAE attacks.

Condition or disease Intervention/treatment Phase
Hereditary Angioedema Biological: C1 esterase inhibitor [human] (C1INH-nf) Phase 3

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 146 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Prevention
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

Arm Intervention/treatment
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)

Primary Outcome Measures :
  1. 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.

Other Outcome Measures:
  1. 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.

  2. 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).

  3. 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.

Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

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
