About this study
Official title: A Multi-Center, Prospective, Clinical Trial Designed to Study the Efficacy of One-Way Valve Implantation Based on a New Treatment Algorithm in Patients With Heterogeneous Emphysema
The purpose of this study is to assess the efficacy of a new treatment algorithm for bronchoscopic lung volume reduction (BLVR) in patients with emphysema based on the information of emphysema heterogeneity, destruction score, and fissure analysis.
Read the detailed description
Emphysema is a progressive pulmonary disease characterized by abnormal and permanent enlargement of air spaces distal to terminal bronchioles accompanied by the destruction of pulmonary parenchyma. Treatment includes inhaled bronchodilator therapy, rehabilitation and/or oxygen treatment. In addition to the above, patients with severe emphysema may benefit from surgical lung volume reduction and/or lung transplantation. The rationale for lung volume reduction surgery is that reducing lung size would restore elastic recoil of the lung and improve chest wall and diaphragm mechanics. It has previously been shown that particularly patients with heterogeneous emphysema seem to benefit most from surgical lung volume reduction.
Bronchoscopic lung volume reduction (BLVR) has recently been introduced as a less invasive potential alternative to surgical lung volume reduction. BLVR attempts to achieve the effects of surgery, by placing bronchial prostheses using a fibreoptic bronchoscope to selectively occlude the airways supplying the most affected hyperinflated regions of the emphysematous lung, while permitting exhaled gas to escape. This attempts to achieve segmental or lobar volume reduction, simulating the effects of surgical LVR. Recent trials of BLVR using endobronchial one-way valves demonstrated significant improvements in lung function parameters, exercise capacity and quality of life in patients with end-stage emphysema. The treatment algorithm for valve implantations to achieve BLVR, however, varied considerably in these reports as well as clinical and functional response rates. Subset analysis of these studies revealed that particularly, but not exclusively, patients with radiological signs of lung volume reduction treated unilaterally showed significant clinical improvements, whereas most patients without signs of lung volume reduction did not experience these benefits. The present study investigates the response to BLVR based on a new treatment algorithm including lung function criteria and computed tomography of the thorax.

The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 13 inclusion and 19 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 8 Aug 2008. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 3 sites in Belgium, Austria. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

How can a doctor refer a patient or contact the research team?
Contact Arschang Valipour, MD (+43-1-91060-41833, arschang.valipour@wienkav.at), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Mean % change in lung function (FEV1) (time frame: 90 days post index bronchoscopic lung volume reduction). 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 8 Aug 2008; AzTrials last refreshed its copy on 8 Nov 2026.
