简要总结
This is a Phase 3, multicenter, randomized, double-blind, placebo-controlled study to evaluate the efficacy and safety of once-daily orally administered deucrictibant extended-release tablet compared to placebo for prophylaxis to prevent angioedema attacks in participants aged ≥ 12 years with hereditary angioedema.
详细描述
The study consists of a Screening Period during which eligibility is confirmed, a Treatment Period of 24 weeks, and a Follow-up Period of maximum 4 weeks or subjects may roll over into the open-label study PHA022121-C307 (CHAPTER-4). During the Treatment period participants will receive blinded study drug (deucrictibant or placebo randomized in a 2:1 ratio). Participants will undergo regular efficacy and safety assessments, complete an electronic diary daily, and also complete questionnaires at predefined timepoints during the study.
