About this study

Official title: Comparative Study of Bronchoscopic Lung Volume Reduction to Evaluate Relative Efficacy in Patients With Non-Upper Lobe Emphysema

Hypothesis: Patients with advanced emphysema with predominance of the disease in areas other than the upper lobes, as determined by high resolution computed tomography (HRCT), could have a positive response to valve treatment.

Being tested
Intra-bronchial valve (Spiration IBV)
Keywords
intrabronchial valve, heterogeneous emphysema, non-upper lobe

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Intra-bronchial valve (Spiration IBV)Device

    Also called Spiration IBV

    Device: Intra-bronchial valve (Spiration IBV) The IBV is comprised of a Nitnol frame and a polymer membrane, which is held against the airway mucosa by six elastic struts and will expand and contract with airway movement during breathing. The valve is designed to conform to the size and shape of the airways. The frame has 5 flexible anchors that gently secure to the mucosal wall at a controlled depth. Valves are available in 5, 6 and 7mm diameters appropriate for different airways. During a minimally invasive procedure, a catheter is passed through a bronchoscope (a flexible tube passed into the airways through the mouth) to deploy the umbrella-shaped valves into the airways. Only flexible bronchoscopy equipment is required. The valves are designed to be removed if indicated.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Intra-bronchial valve (Spiration IBV) in people with Heterogeneous Emphysema, run by Royal Brompton & Harefield NHS Foundation Trust at 1 site in United Kingdom.

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 9 inclusion and 20 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: finished, as of the sponsor's last update on 6 Feb 2012. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United Kingdom. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

To estimate the difference between study arms in volume changes of the treated lobe(s) by CT scan (time frame: 6 months). 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 6 Feb 2012.
