Could a Pulsed-Air device revolutionize mucus clearance for bronchiectasis?
NCT ID NCT06237348
First seen Aug 20, 2026 · Last updated Aug 21, 2026 · Updated 1 time
Summary
This trial tests whether a device called Simeox, which uses pulsed air to help loosen and clear mucus from the airways, can improve lung function and quality of life in people with bronchiectasis who produce excess mucus. About 50 adults with the condition will use either Simeox or standard chest physiotherapy at home for two months. Researchers will track how often participants use the device, their symptoms, and any side effects to see if this technology is a practical and beneficial option.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Simeox, a device that uses pulsed air to help clear mucus from the airways, compared with usual chest physiotherapy
- What this could lead to
- If it works, Simeox could offer a more effective and convenient way for people with bronchiectasis to clear mucus at home, potentially improving breathing and quality of life.
- What could go wrong
- This is a small pilot study, so results may not be conclusive. The device may not prove more effective than standard physiotherapy, and individual responses can vary.

Inclusion Criteria: * Patient with confirmed diagnosis of bronchiectasis confirmed by High Resolution Computed Tomography (HRCT): idiopathic, post-infective, systemic disease, ABPA, asthma, COPD, PCD * Overproduction of mucus (ie: estimated bronchorrhea \>10mL/day). * Pulmonary exacerbation (in- or outpatients) * Age \> 18 years old * Patient able to understand the study and to perform the 2-month follow up visit Exclusion Criteria: * Pneumothorax/pneumo-mediastinum in the six months prior hospitalization * Recent episode of severe haemoptysis * Unstable severe cardiac disease or hemodynamic instability * Cystic fibrosis or COPD as dominant diagnosis * Patient on lung transplant list * Severe lung injuries * Recent lung surgery * Inhalation support (continuous ventilatory support) * Tracheostomy * Uncontrolled GERD * Any contraindication to an instrumental bronchial clearance technique (up to the investigator) * Inability to perform PFT or 6MWT * Patient not available or wishing to move to a different region within 2 months of inclusion * Patient considered by the investigator to be physically or mentally inapt to use the device and/or to perform the study procedures. * Patient currently participating or having participated within one month prior to inclusion in a clinical intervention research trial that may impact the study, the impact of which is up to the investigator
