What this trial studies

This clinical trial investigates the use of lanadelumab, a monoclonal antibody, for the long-term prevention of recurrent attacks in patients diagnosed with acquired angioedema (AAE). Participants will receive a dose of 300 mg of lanadelumab to assess its efficacy in reducing the frequency of angioedema episodes. The study focuses on patients with specific diagnostic criteria, including decreased C1INH levels and the presence of anti-C1INH antibodies. The goal is to provide a new therapeutic option for managing this condition.

Who should consider this trial

Good fit: Ideal candidates for this study are individuals diagnosed with acquired angioedema who experience recurrent attacks and meet specific laboratory criteria.

Not a fit: Patients with hereditary angioedema types 1 or 2 or those with well-controlled major systemic diseases may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly reduce the frequency and severity of angioedema attacks for patients suffering from AAE.

How similar studies have performed: While this approach is focused on acquired angioedema, similar studies using monoclonal antibodies for other types of angioedema have shown promising results.
