Brief Summary
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.

Eligibility Criteria
You may qualify if:
- Documented diagnosis of HAE (type I or II). The following must be met:
- a. Documented clinical history consistent with HAE (for example, subcutaneous or mucosal, nonpruritic swelling episodes without accompanying urticaria).
- Experienced at least 2 HAE attacks during the Run-In period, as confirmed by an investigator based on meeting the protocol-specified definition of an HAE attack.
You may not qualify if:
- Any concomitant diagnosis of another form of chronic angioedema, such as acquired C1 inhibitor deficiency, HAE with normal C1-INH (also known as HAE type III), idiopathic angioedema, or angioedema associated with urticaria.
- Use of therapies prescribed for the prevention of HAE attacks prior to Screening:
- lanadelumab within 90 days
- berotralstat within 21 days
- all other prophylactic therapies, within 7 days
- Any exposure to angiotensin-converting enzyme inhibitors or any estrogen containing medications with systemic absorption (such as hormonal contraceptives or hormone replacement therapy) within 28 days prior to Screening.
- Any exposure to androgens (for example, stanozolol, danazol, oxandrolone, methyltestosterone, testosterone) within 7 days prior to Screening.
