Summary
The objectives of the study are to:
1. Evaluate the safety and tolerability of CINRYZE administered by subcutaneous injection in subjects with hereditary angioedema
2. Characterize the pharmacokinetics and pharmacodynamics of CINRYZE administered by subcutaneous injection
3. Assess the immunogenicity of CINRYZE following subcutaneous administration
