About this study
This is a double-blind randomised controlled crossover study to investigate whether high frequency airflow oscillation (HFAO), delivered using Aerosure, improves sputum clearance in patients admitted to hospital with infective exacerbations of cystic fibrosis (CF). This study will test the hypothesis that the wet weight of sputum expectorated is greater following the use of Aerosure than following the use of a sham Aerosure device.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Aerosure at 15 Hz and Aerosure at 25 Hz in people with Cystic Fibrosis, run by Actegy Ltd. at 1 site in United Kingdom.
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 2 inclusion and 21 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: stopped early, as of the sponsor's last update on 3 Jun 2016. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United Kingdom. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
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 was stopped early (reason given: Unable to recruit sufficient patients within reasonable timeframe). Results are not available in the source record.
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?
Wet weight of sputum expectorated during treatment session (time frame: up to 30 minutes after treatment). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 3 Jun 2016; AzTrials last refreshed its copy on 7 Nov 2026.
