The study objective was to describe the pharmacokinetics (PK) of one or two doses of C1 esterase inhibitor (C1INH-nf) in hereditary angioedema (HAE) subjects who were not experiencing an HAE attack.

Condition Intervention Phase
Hereditary Angioedema Drug: C1 esterase inhibitor [human] (C1INH-nf) Phase 1

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Official Title: Protocol LEVP2006-5: Pharmacokinetics of C1INH-nf in Hereditary Angioedema Subjects

Further study details as provided by Shire:

Primary Outcome Measures:
  • PK will be analyzed by means of incremental recovery, in vivo half-life, area under the curve, clearance, and mean residence time. [ Time Frame: 1 week ]
  • C1 inhibitor (functional and antigenic) and C4 antigen serum levels will be measured at a United States Clinical Laboratory Improvement Amendments-certified laboratory and the research division of Sanquin Blood Supply Foundation. [ Time Frame: 1 week ]

Secondary Outcome Measures:
  • Number and severity of adverse events. [ Time Frame: 3 months ]
  • Change in clinical laboratory safety parameters from pre- to post-infusion. [ Time Frame: 3 months ]
  • Change in vital signs from pre- to post-infusion. [ Time Frame: 30 minutes (Single Dose), 90 minutes (First Dose Followed by Second Dose) ]

Enrollment: 27
Study Start Date: October 2006
Study Completion Date: June 2007
Primary Completion Date: March 2007 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Single Dose
1,000 Units (U) of C1INH-nf administered intravenously (IV).
Drug: C1 esterase inhibitor [human] (C1INH-nf)
Experimental: First Dose Followed by Second Dose
1,000 U of C1INH-nf administered IV, followed by a second 1,000 U dose 60 minutes later.
Drug: C1 esterase inhibitor [human] (C1INH-nf)
