AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion criteria
. Provision of written informed consent.
. Male or female, aged ≥18 at the time of provision of informed consent.
. Diagnosis of bradykinin-mediated angioedema based upon all of the following:

. Reliable access and experience to use standard of care medication to effectively manage acute angioedema attacks.
Exclusion criteria
. Any diagnosis of angioedema other than BK-AE-nC1INH.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Part-1: Incidence and quality of HAE attacks comparing active versus placebo arms.
Timeframe: 24 weeks
2
Part-2: Efficacy of active on-demand treatment versus placebo in achieving angioedema symptom relief during acute attacks
. Participation in a clinical study with any other investigational drug within the previous 30 days or within 5 half-lives of the investigational drug at Screening (whichever was longer).
. Exposure to angiotensin-converting enzyme (ACE) inhibitors or any estrogen-containing medications with systemic absorption (such as oral contraceptives or hormonal replacement therapy) within 4 weeks of Screening.
. Receiving prophylactic treatment for BK-AE-nC1INH. Participants who have previously received prophylactic therapy but have stopped can participate in this study provided a sufficiently long washout period (≥5 half-life) is observed before the participant is screened. Exclusion includes use of:
. Any females who are pregnant, plan to become pregnant, or are currently breast-feeding.
. Abnormal hepatic function (aspartate aminotransferase \>2× upper limit of normal, alanine aminotransferase \>2× ULN, or total bilirubin \>1.5× upper limit of normal). Participants with Gilbert's syndrome, defined as isolated increase of total bilirubin ≤3× upper limit of normal and aspartate aminotransferase and alanine aminotransferase within the normal range, are not excluded.
. Any clinically significant history of angina, myocardial infarction, syncope, stroke, left ventricular hypertrophy or cardiomyopathy, uncontrolled hypertension, bradycardia, or any other clinically significant cardiovascular abnormality within the previous year that, in the opinion of the Investigator, would interfere with the participant's safety or ability to participate in the study.
