Dose-ranging Study of Oral PHA-022121 for Prophylaxis Against Angioedema Attacks in Patients With Hereditary Angioedema Type I or Type II

Study Purpose

This study evaluates the safety and efficacy of PHA-022121 administered orally for prophylaxis against angioedema attacks in patients with hereditary angioedema (HAE). The study consists of 2 parts, with patients completing participation in Part 1 prior to initiation of treatment in Part 2. Part 1 of the study has 3 parallel arms and approximately 30 patients will be equally randomized to one of two dose regimens of PHA-022121 or matching placebo. Patients will continue to the single open-label arm in Part 2 of the study after completion of Part 1. The screening period is up to 8 weeks and the treatment periods are 12 weeks (Part 1) and 30 months (Part 2) in duration.
