NCT ID NCT05469789
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 2 times
Summary
This study follows 50 people in the UK with hereditary angioedema (HAE) types I or II who are taking lanadelumab. Researchers will compare the number of HAE attacks in the year before starting the drug to up to two years after. The goal is to see how well the drug works outside of clinical trials, using patient diaries and medical records.
