An interventional study of SIMEOX and Remote Physiotherapy in Non-cystic Fibrosis Bronchiectasis, sponsored by Physio-Assist. Recruiting at 57 sites in 6 countries. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-11-02.
Sponsored by Physio-Assist · Not applicable, Interventional, and Treatment
Bronchiectasis is a chronic lung disease of multiple aetiologies characterised by permanent dilatation of the calibre of a territory of the bronchial tree with impaired mucociliary clearance. This alteration causes mucus retention, leading to infections and chronic bronchial inflammation. Respiratory physiotherapy is one of the cornerstones of the management of these patients, in particular to facilitate bronchial drainage. In patients with abundant bronchial secretions, it is recommended that bronchial drainage sessions be carried out on a daily or more frequent basis, which represents a very substantial burden in terms of care. In addition, access to respiratory physiotherapy is not always easy for patients due to geographical or time constraints or the availability of professionals. Moreover, few professionals are trained in this specific care for chronic lung diseases.
SIMEOX (Physio-Assist, France) is an innovative medical device (CE medical mark) for draining the bronchial tree. By means of a mouthpiece, this device generates a succession of very short intermittent negative air pressure pulses which disseminate a pneumatic vibratory signal in the patient's bronchial tree, modifying the rheological properties of the mucus, facilitating the mobilisation of secretions and assisting their transport towards the upper airways.
A recent pilot study demonstrated that the use of SIMEOX independently by the patient at home for 3 months, combined with remote Physiotherapy (1 session/2 weeks), provided a very satisfactory bronchial drainage solution for patients (satisfaction assessed at 9/10 by visual analogue scale), with an improvement in their quality of life and very good compliance with the device (median of 4.7 sessions/week).
This bronchial drainage strategy requires a long-term assessment.
Hypothesis: the use of SIMEOX independently by the patient at home could improve long-term quality of life and reduce the rate of pulmonary exacerbations in non-cystic fibrosis (non-CF) patients with bronchiectasis (bronchial dilatation) in comparison to Standard of Care (SoC).
Two main objectives will be assessed sequentially:
404 studies on the registry are indexed under Bronchiectasis; 125 are open to participants now.
This study's planned enrollment of 468 is above the median of 60 across 263 interventional studies indexed under Bronchiectasis.

Clinically stable at inclusion
Or Having had at least one pulmonary exacerbation in the 12 months prior to inclusion requiring hospitalisation.
Exclusion Criteria:
Patients using one of the following motorised mechanical bronchial drainage devices at home at the time of inclusion:
Patients who have been using a powered mechanical cough aid at home for less than a year at the time of inclusion:
However, patients with COPD or asthma and concomitant bronchiectasis may be eligible if they present symptoms of bronchiectasis (e. g. persistent cough, excessive mucus production, fatigue, shortness of breath, chest pain, etc.) and meet the following conditions:
For patients with asthma: documented evidence of bronchiectasis exacerbations (e.g., increased sputum production, sputum purulence, or infective exacerbation) requiring treatment with antibiotics, rather than exacerbation predominantly caused by bronchospasm or loss of asthma control
Vulnerable people:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Chronic obstructive pulmonary disease: long-term lung disease that makes it hard to breathe out, including emphysema and chronic bronchitis.
A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.
Read whether the line is about a condition or about medicines, and which medicines and doses it means.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
