NCT ID: NCT02022683 Completed - COPD Clinical Trials

To Improve Lung Function and Symptoms for Emphysema Patients Using Zephyr Valves

TRANSFORM
Start date: January 28, 2014
Phase: N/A
Study type: Interventional

To compare the clinical outcomes of Endoscopic Lung Volume Reduction (ELVR) using Pulmonx Zephyr Valves vs. Standard of Care (SoC) in the treatment of heterogeneous emphysema subjects in a controlled trial design setting.

NCT ID: NCT01902732 Recruiting - Clinical trials for Heterogeneous Emphysema

Endoscopic Lung Volume Reduction After Catheter-based CV Measurement in Patients With Heterogeneous Emphysema and Complete Interlobar Fissures

Start date: June 2013
Phase: Phase 2/Phase 3
Study type: Interventional

This clinical trial evaluates the impact of catheter-based measurement of interloabr collateral ventilation prior to endoscopic lung volume reduction in patients with hetereogeneous emphysema and complete interlobar fissures in high resolution computed tomography.

NCT ID: NCT00825578 Completed - Clinical trials for Heterogeneous Emphysema

Use of Endobronchial Valves in Non-Upper Lobe Heterogeneous Emphysema

Start date: January 2009
Phase: Phase 3
Study type: Interventional

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.

NCT ID: NCT00684892 Completed - Clinical trials for Heterogeneous Emphysema

Safety and Feasibility Study of the Chartis System With Heterogeneous Emphysema Prior to Endobronchial Lung Volume Reduction (ELVR)

Start date: May 2008
Phase: Phase 1/Phase 2
Study type: Interventional

The purpose of this study is to evaluate the safety and feasibility of the Chartis System in measuring air flow and pressures in isolated lung compartments in emphysema patients prior to endobronchial lung volume reduction (ELVR).
