This is a Phase 1b/2 single and multiple dose trial evaluating the safety, tolerability, clinical activity, pharmacokinetics, pharmacodynamics, and immunogenicity of subcutaneous administration of STAR-0215 in participants with type I or type II HAE in 3 dose cohorts. The first cohort will receive 1 dose of STAR-0215; the second and third cohorts will receive 2 sequential doses. This is the first trial of STAR-0215 in participants with HAE and the first evaluation of a multiple-dose regimen.
The goal of this clinical trial is to test the drug STAR-0215 in participants with hereditary angioedema (HAE). One group of participants will get 1 dose of STAR-0215, and two other groups will get 2 doses of STAR-0215. Researchers will study the effects of STAR-0215 in participants with HAE as this is the first time that the drug has been given to participants with HAE.
