NCT ID NCT06467084

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tested a drug called sebetralstat in 36 children aged 2 to 11 with hereditary angioedema (HAE) types I or II, a condition that causes sudden, painful swelling. The goal was to see if the drug is safe and how well it works to relieve attacks. The trial was open-label, meaning everyone knew they were getting the drug, and it has already been completed.
