•F.1.2 Adults (18-64 years) no
•F.1.2.1 Number of subjects for this age range
•F.1.3 Elderly (>=65 years) no
•F.1.3.1 Number of subjects for this age range

•Patients who meet any of the following criteria will be excluded from the study.
•1.Are <2 years of age or have reached puberty (as assessed by Tanner Stage 2; at the screening visit)
•2.Received treatment with ecallantide within previous 72 hours (at pre-dose of Parts 1, 2, and 3)
