About this study
Official title: A Phase III Multicenter, Randomised, Parallel, Placebo-Controlled, Double-Blind Study to Investigate the Safety and Efficacy of Treatment With Bronchitol (Dry Powder Mannitol) in the Symptomatic Treatment of Bronchiectasis.
Study will assess the safety and effectiveness of 12 week treatment with the study medication, Bronchitol, in subjects with bronchiectasis (a lung disease where patients have trapped, and often infected, thick, sticky mucus). Past studies have shown Bronchitol inhalation may help to facilitate the clearance of mucus by altering its rheology (making it less thick and sticky), thereby enhancing the shift of stagnant mucus from the lungs. On completion of the double blind phase, subjects will have the opportunity to participate in a 52 week open label phase.

A Phase 3 study testing Mannitol in people with Bronchiectasis, run by Syntara at 22 sites in 3 countries.
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 2 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 29 Aug 2008. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 22 sites in Australia, United Kingdom, New Zealand. 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. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
24 hour sputum clearance (time frame: 24 hours / 12 weeks). The study lists 2 primary outcomes in all. 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 NCT00277537, 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 29 Aug 2008; AzTrials last refreshed its copy on 7 Nov 2026.
