The official eligibility criteria
Registry text, reproduced exactly. These are the words the trial's sponsor published on ClinicalTrials.gov. They have not been edited, shortened or rewritten, and they are written for researchers rather than for patients.
Key Inclusion Criteria:
1. Must be between the ages of 2 and less than 12 years, inclusive, at the time of informed consent and, as applicable, assent.
2. Must weigh at least 9 kg at the time of informed consent and, as applicable, assent.
3. Documented diagnosis of HAE-1/HAE-2 based upon both of the following:
1. Documented clinical history consistent with HAE (SC or mucosal, non-pruritic swelling episodes without accompanying urticaria).
2. Diagnostic testing results that confirm HAE-1/HAE-2: C1-inhibitor (C1-INH) functional level \<50% normal level AND complement factor C4 level below the lower limit of normal (LLN); OR a known pathogenic mutation in the SERPING1 gene.
Key Exclusion Criteria:
1. Must not have any screening laboratory abnormalities or any other clinically significant abnormalities during screening that would render a participant unsuitable for inclusion.
2. Must not have been treated with another investigational drug, biological agent, or device within 1 month of Screening, or 5 half-lives of investigational agent, whichever is longer.
3. Concurrent diagnosis of any other type of recurrent angioedema, including idiopathic angioedema or HAE with normal C1-INH (HAE-nC1-INH or Type III).

Not medical advice.
Individual trial records are refreshed on a rolling basis rather than all at once, so a record may be up to several weeks old. Each trial page and trial card shows the date its own record was last synced. Where a record has lagged, its status, sites and enrolment can differ from the current registry state in either direction, so check the registry link on the trial page before acting on them.
