Prevention of OM-85 on Bronchiectasis Exacerbation

• Status: Completed
• Trial end date: 2018-11-23
• Target enrollment: 0
• Participant gender: All

Summary

Non-cystic fibrosis bronchiectasis is characterized by irreversible dilatation of the medium-sized bronchi as a result of airway injury due to recurrent or chronic inflammation and infection. Bronchiectasis airways are often colonized with bacterial species. Infections of the airways are thought to play an important role in bronchiectasis exacerbation. The non-specific prevention of recurrent airway infections by immunostimulating agents has gained growing scientific interest. OM-85, consisting extracts of eight kinds of bacteria important in respiratory infections, has shown the benefit for significantly reducing the incidence of exacerbations of chronic obstructive pulmonary disease (COPD). The purpose of this study is to investigate the PReventive effect of OM-85 on Bronchiectasis Exacerbation in Chinese patients (iPROBE).

This study is designed as a prospective randomised double-blind placebo-controlled multi-centred trial.
