Chronic Obstructive Pulmonary Disease (COPD)NCT02246569
Lung Volume Reduction Via Coils in Patients With COPD
An observational study of Chronic Obstructive Pulmonary Disease (COPD), run by RWTH Aachen University at 1 site in Germany.
Trial summary
For patients with emphysema lung volume reduction (ELVR) could be an expedient approach for the reduction of distension of the lung. ELVR may be performed using RePneu® Coils. After the insertion of the coils distended lung sections shrink so that healthy parts can expand. Read more about this study

About this study
Official title: Impact of Endoscopic Lung Volume Reduction Via Coils on Inspiratory Muscle Strength in Patients With COPD
For patients with emphysema lung volume reduction (ELVR) could be an expedient approach for the reduction of distension of the lung. ELVR may be performed using RePneu® Coils. After the insertion of the coils distended lung sections shrink so that healthy parts can expand.
In the present study investigators intend to examine, whether the insertion of the coils improves diaphragm function and force of the breathing muscles. Investigators hypothesize that reduction of lung volume eliminates or reduces flattening of the diaphragm and relieves breathing muscles, respectively respiratory pump, which aims to reduce dyspnea.
Read the detailed description
In line with routine explorations it is necessary to clarify whether a patient is suitable for the endoscopic lung volume reduction. To address this question lung function diagnostics, 6-minutes-walk-test, blood withdrawal, CT of the thorax, lung perfusion scintigraphy and transthoracic echocardiography have to be performed.
After confirmation of the suitability for the endoscopic lung volume reduction patients who fulfill all other eligibility criteria will be educated about the aim and performance of the study by an investigator. After reading the patient information patient may submit his informed written consent. After that information on the risks will be given by a treating physician.
Following examination will be performed additional due to the study: determination of the strength of breathing muscles, determination of the life quality index via St.-George-questionary and determination of the depression score via SF-8-questionary (short form-8).
After that coils will be implanted and a permanent post-operative examination will be performed for 24 hours.
Three, respectively nine month after the implanting follow up exploration will be performed on the study patients.

breathing strength (time frame: Change of breathing strength 3 (respectively 9) months after the bronchoscopy). 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 20 Nov 2015.
