Long-Term, Open-label Study of Oral Deucrictibant Extended-Release Tablet for Prophylaxis Against Angioedema Attacks in Adolescents and Adults With HAE

170 patients around the world

Available in Argentina, United States, Brazil

The study consists of a Screening Period during which eligibility is confirmed (only for participants not rolling over within 28 days from a previous deucrictibant prophylactic study), a Treatment Period in which participants will receive open-label deucrictibant extended-release tablet once daily for approximately 130 weeks, followed by an End of Study visit after maximum 4 weeks. Participants will undergo regular safety (e.g. lab draws) and efficacy assessments, will complete an electronic diary daily, and also complete questionnaires at predefined timepoints during the study.
