A Randomized, Double-blind, Placebo-controlled, Dose-ranging, Study to Evaluate the Efficacy, Safety and Tolerability of Single Doses of BCX7353 as an Acute Attack Treatment in Subjects With Hereditary Angioedema
In Brief
A Phase 2 clinical trial evaluating BCX7353 and Placebo for Hereditary Angioedema (HAE). Completed, enrolled 58 participants across 24 sites in 12 countries.
Detailed Summary
This 3-part study will evaluate the efficacy and safety of an oral kallikrein inhibitor, BCX7353, in the treatment angioedema attacks in subjects with Type I or II hereditary angioedema (HAE). In each study part, subjects will treat 3 attacks with BCX7353 (2 attacks) or placebo (1 attack), in a randomly allocated order. In Part 1, the dose of 750mg will be assessed relative to placebo in up to 36 patients. If this is shown to be effective, then a further 12 patients will be enrolled at a 500mg dose (Part 1), followed by a further 12 (if efficacy still shown) at a dose of 250mg (Part 3) to determine the minimum effective dose of BCX7353 compared to placebo for treating HAE attacks. Efficacy will be determined by subject diary entries completed at pre-defined times post-dose.
