BioCryst to explore oral liquid formulation of BCX7353 for use in Acute HAE attacks
Biocryst announced that it has received approvals from Europe’s initial regulatory to explore a new Oral liquid formulation of BCX7353 for the treatment of Acute attacks in patients with HAE (Hereditary angioedema).
The Company will initiate the ZENITH-1 exploratory clinical trial this summer.
The purpose is to explore whether single oral doses of a liquid formulation of BCX7353 could have utility in the treatment of acute angioedema attacks in patients with HAE. It is designed as a randomized, double-blind, placebo controlled, dose-ranging trial with BCX7353 self-administered at home to treat attacks. Additional information and clinical trial design will be provided upon completion of the regulatory process and trial initiation.
Jon Stonehouse, CEo said that to complement the attractive profile of their prophylactic treatment program, as evidenced by the interim results from our APeX-1 trial, they made a decision to explore an additional indication for the treatment of acute attacks with a new oral liquid formulation. The rapid absorption and long half-life of BCX7353 observed after single oral doses in healthy volunteers, and the strong encouragement from disease experts and patient advocates have motivated us to explore ‘7353 as an acute treatment. They believe this new formulation can fill an unmet need for patients with less frequent attacks who are looking for better ways to manage their illness. This initiative has the potential to provide patients with a more convenient option for the treatment of acute attacks, and if successful, the first oral acute therapy for HAE.

Discovered by BioCryst, selective inhibitor of plasma kallikrein currently in development for the prevention of angioedema attacks in patients diagnosed with HAE. With the initiation of the ZENITH-1 clinical trial, the oral liquid formulation of BCX7353 will be evaluated for treating acute angioedema attacks. BCX7353 has been generally safe and well tolerated in the ongoing Phase 2 ApeX-1 clinical trial and in clinical pharmacology studies in healthy volunteers.
