Sebetralstat (KVD900) for Hereditary Angioedema Prophylaxis

This study is testing a drug called sebetralstat (KVD900) to see how safe and effective it is at preventing swelling attacks in people with Hereditary Angioedema (HAE) before they have medical procedures. HAE is a rare genetic condition that causes episodes of severe swelling. The study aims to see how many procedures don't lead to an HAE attack within 24 hours after the procedure starts when sebetralstat is used. You may be able to join if you are 12 years or older, have a confirmed diagnosis of HAE Type I or II, and have a procedure scheduled soon. The study is currently recruiting about 100 participants, but its overall status is unclear.

Study design
This is a Phase 4, open-label study, meaning both you and your doctors will know you are receiving sebetralstat. It plans to enroll about 100 participants.
