What this trial studies

This trial aims to gather information on the long-term safety and clinical effectiveness of STAR-0215 in individuals with hereditary angioedema (HAE). Participants will receive repeated doses of STAR-0215 over a period of up to five years. The study is designed to include both participants who have previously been part of another related trial and those who are new to STAR-0215 but have a documented diagnosis of HAE. The focus is on monitoring the safety and clinical activity of the treatment throughout the study duration.

Who should consider this trial

Good fit: Ideal candidates include individuals with a documented diagnosis of hereditary angioedema, either previously treated with STAR-0215 or new participants.

Not a fit: Patients who do not have a diagnosis of hereditary angioedema or those who have contraindications to STAR-0215 may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly improve the management of hereditary angioedema for patients.

How similar studies have performed: Other studies involving long-term treatments for hereditary angioedema have shown promise, indicating that this approach may be beneficial.

Eligibility criteria

Inclusion Criteria:

* Open to participants from STAR-0215-201 (NCT05695248) who have met one of the following conditions:

  * Completed STAR-0215-201 (follow up through 6 months after their last dose);
  * Eligible for STAR-0215-201 and entered the Run-In period but did not qualify for the Treatment Period because they did not meet the criterion for the minimum number of HAE attacks;
  * Eligible for STAR-0215-201 and entered the Run-In period but did not complete it for reasons other than not meeting the criterion for the minimum number of HAE attacks (eligibility requires consultation with the Medical Monitor); or
  * Discontinued STAR-0215-201 (for reasons other than safety) after having completed at least 84 days of trial follow-up since their last dose of STAR-0215 (eligibility requires consultation with the Medical Monitor).
* Open to participants who are STAR-0215 naïve and were not enrolled in STAR-0215-201 (NCT05695248), have a documented diagnosis of HAE (Type 1 or Type 2).

Exclusion Criteria:

* Any concomitant diagnosis of another form of chronic angioedema, such as acquired C1 inhibitor deficiency, HAE with normal C1-esterase inhibitor protein (also known as HAE Type III), idiopathic angioedema, or angioedema associated with urticaria.
* 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.
