Summary

This study looks at the long-term safety of an oral medication called KVD900 for treating sudden swelling attacks in people with hereditary angioedema (HAE) types I or II. About 145 adolescents and adults who previously took part in a related study will take KVD900 as needed for attacks. The goal is to see if the drug is safe over time and how well it controls symptoms.
