CHI25243, a novel potent inhaled inhibitor of neutrophil elastase for the treatment of bronchiectasis and other chronic inflammatory lung disease

Investigational inhaled therapies for non-CF bronchiectasis

INTRODUCTION

Bronchiectasis not related to cystic fibrosis (non-CF bronchiectasis) are associated with a high unmet therapeutic need due to the lack of specifically authorized medications, especially via the inhalation route. In non-CF bronchiectasis chronic infection with Pseudomonas aeruginosa is common and favored by the persistent local inflammation and viscid sputum production. Therefore inhaled antibiotics, mucolytics or anti-inflammatory agents could represent appropriate therapeutic interventions in this setting.

AREAS COVERED

This review herein discusses the inhaled therapies currently under investigation for non-CF bronchiectasis and their potential therapeutic positioning in exacerbation versus stable state.

EXPERT OPINION

Inhaled antipseudomonal antibiotics are of promising efficacy, but further efforts should also be made to detect bactericidal approaches against Burkholderia cepacia complex, and to interfere chronic inflammation topically.
