Biological Investigation of Explanted Endobronchial Lung Valves Study — Bio-EXCEL  

Emphysema or COPD Clinical Trial

Official title:
Biological Investigation of Explanted Endobronchial Lung Valves Study - Investigation of the Mechanism of Action of Tissue-device Interactions

Clinical Trial Summary

Rationale: COPD is a severe, often progressive and currently incurable lung disease which affects both the upper airways (chronic bronchitis) as well as the lower airways (emphysema). In advanced stages of the disease air-trapping severely reduces the ability to breathe and subsequently the quality of life. A highly effective treatment for restoring lung mechanical functionality of these patients is the introduction of bronchoscopic lung volume reduction (BLVR), e.g. implanting small silicone/nitinol valves (EBV) inside the airways to reduce air-trapping. Although successfully investigated in a selected group of severe COPD patients, the effectiveness of the treatment can sometimes be short-lived due to fibrotic and granulation responses and tissue-material interactions. Objective: The main objective of this study is to study and understand the underlying biological principles of granulation and fibrotic responses limiting the effectiveness and longevity of BELVR treatment with EBVs, this to investigate the mechanism of action of tissue-device interactions.
