Hereditary Angioedema Clinical Trial
Official title:
A Phase II, Double-blind, Placebo-controlled, Randomized, Cross-over, Dose-ranging Study of Oral PHA-022121 for Acute Treatment of Angioedema Attacks in Patients With Hereditary Angioedema Due to C1-inhibitor Deficiency Type I and II
This study evaluates the efficacy of orally administered deucrictibant for the acute treatment of attacks in patients with hereditary angioedema (HAE). Eligible subjects are randomized to one of three single doses of deucrictibant and placebo. The study will compare symptom relief (skin pain, skin swelling, abdominal pain) during HAE attacks and safety of each dose of deucrictibant with placebo.
In Part I of the study, patients in non-attack state receive the assigned active single dose of deucrictibant at the study center to assess pharmacokinetics (the way the body absorbs, distributes, and gets rid of the drug) and safety. In Part II of the study, patients self-administer blinded study drug at home to treat three HAE attacks with deucrictibant or placebo (cross-over). ;
