About this study

Official title: To Investigate the PRevention of OM-85 on Bronchiectasis Exacerbation (iPROBE): a Multicenter, Randomised, Double-dummy, Placebo-controlled Clinical Trial in Chinese Patients

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.

Read the detailed description

Bronchiectasis is still a common chronic respiratory disease. 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. Clinical features of bronchiectasis include chronic production of sputum often mucopurulent or purulent in nature, persistent bacterial colonization, recurrent lower respiratory tract infections. Bronchiectasis airways are often colonized with bacterial species. Infections of the airways are thought to play an important role in bronchiectasis exacerbation. Progressive lung damage in bronchiectasis results from a 'vicious cycle' of recurrent bacterial infection and a deregulated inflammatory response. 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 been known to support the respiratory tract resistance to the pathogens via activating pulmonary macrophages, increasing the ratio of CD4 to CD8 lymphocytes, and changing the level of a variety of cytokines in the lung. OM-85 has shown the benefit for significantly reducing the incidence of exacerbations of chronic obstructive pulmonary disease (COPD). Bronchiectasis exacerbations contribute substantially to rapid decline in lung function, reduced quality of life, and the medical costs. 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. A total of 244 patients with bronchiectasis, who have had at least one exacerbation of bronchiectasis in the previous year, will be included. The subjects will be randomly received two courses of 7mg of OM-85 or matching placebo to take one oral capsule per day for 10 days a month for 3 consecutive months at the beginning of the study, then 3 months later with the same schedule for 1 year.

We will investigate whether long-term therapy with an oral immunostimulant OM-85 can decrease exacerbations in patients with bronchiectasis over 1-year period. Besides, we will assess other outcomes including: the rate of event-based exacerbation, lung function parameters, the total scores on the St George's respiratory questionnaire and coughing, and inflammatory index. We hope that this study will provide novel information on the preventive effects of OM-85 treatment on bronchiectasis exacerbation and will address a knowledge gap for this poorly understood and under-studied disease.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing OM-85 BV in people with Bronchiectasis With Acute Exacerbation, run by Chinese Academy of Medical Sciences at 2 sites in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 16 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 21 Apr 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 21 Apr 2020). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Bronchiectasis Exacerbation (time frame: 1 year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01968421, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 21 Apr 2020.
