Filter by:Chronic obstructive pulmonary disease (COPD) affects 3.5 million people and is the third leading cause of death worldwide. Emphysema involves air retention in the lungs and is ultimately responsible for a major deterioration in the quality of life. Available drug treatments have moderate efficacy whereas surgical lung volume reduction can improve exercise capacity when offered to a very selected population but at the cost of significant morbidity and mortality. Endoscopic Lung Volume reduction with ZEPHYR® valves improves respiratory function at rest, exercise tolerance and quality of life in patients with little or no interlobar collateral ventilation. If this technique has therefore proven its effectiveness, it is not devoid of complications and is notably responsible for pneumothorax in 27% of cases. The management of this complication is clearly codified, ranging from patient monitoring to the removal of one or more valves. It is therefore a subject of major concern for multiple reasons: high incidence, lengthening of hospital stay, increase in the overall cost of care, potential loss of benefit for the patient in the event of permanent withdrawal. valves and above all a potentially fatal event. A new strategy for implanting ZEPHYR® valves in two stages has been developed in Limoges University Hospital. This innovative algorithm has been evaluated in several non-comparative single or multicenter studies. In those studies, pneumothorax' rate secondary to lung volume reduction with endobronchial valves is rated between 4.5 and 12%. The efficacy of the treatment appears to be comparable with the data found in the trials evaluating in which the entire lobe was treated in one procedure. Moreover, despite two procedures, there does not seem to be any increased risk of occurrence of other complications. Finally, the systematic scheduling of a thoracic computed tomography between the two procedures showed that 26.6% of patients presented a reduction in volume greater than 350mL despite incomplete treatment. These data seem promising but no direct comparison with standard one-step treatment has ever been conducted so far.
To compare the efficacy and safety of subsegmental treatment and segmental treatment with InterVapor in patients with severe emphysema
Phase 2 open label extension study to evaluate INBRX-101 in adults with AATD emphysema
Prospective, 2-arm, randomised (2:1), multicentre, open-label clinical trial in patients with severe emphysema. The intervention arm will be treated with Bronchoscopic lung volume reduction in severe emphysema using thermoablation.The interventional treatment (bronchoscopic lung volume reduction) is compared with the usual conservative standard therapy (GOLD guidelines).
Some sparse scientific data support the hypothesis that otherwise unexplained emphysema may be associated with FLNA mutation. This prospective, monocentric, cross-sectional study aimed to describe the frequency of emphysema in patients carrying an FLNA mutation. Patients with FLNA mutations who accept the study will benefit from a chest physician's clinical examination, respiratory function tests and a chest scan. The primary endpoint is to describe emphysema's frequency in patients carrying FLNA mutation. The other objectives are to describe emphysema's features in these patients and to describe their lung function abnormalities. The final goal is to confirm the association between unexplained emphysema and FLNA mutation.
This study is designed to prospectively document changes in FEV1 and health-related quality of life 12 months following sequential segmental treatment with InterVapor® in patients with heterogeneous emphysema with upper lobe predominance. For validity of the study, the results will be compared to patients that receive optimal medical therapy.
The purpose of this study is evaluating the safety of endobronchial transplantation of autologous mesenchymal stem cells derived bone marrow in patients with emphysema.
This study will test that hypothesis that endoscopic lung volume reduction therapy performed using emphysematous lung sealant treatment can be improved using smaller doses delivered to more a larger number of treatment sites.
COPD is a progressive pulmonary disease that is characterized by an inflammatory process in the airways and the lungs which leads to progressive airway obstruction. The inflammation is associated with tissue loss and remodelling. The investigators hypothesized that doxycycline reduces neutrophilic airway inflammation in patients with COPD. Therefore the investigators will conduct a randomized trial of doxycycline in 30 patients.
