Chronic Obstructive Pulmonary Disease (COPD)
Conditions
Brief summary
The aim of this study is to determine the feasibility of combining a lung sealant with endobronchial valves EBV in managing patients with COPD who are collateral ventilation (CV) positive. This study has two arms; arm 1 is for CV positive participants who will receive the lung sealant and EBV; arm 2 is the CV negative group who will only receive EBV as the standard management.
Interventions
The Aeriseal System uses a polymer foam to block or seal fissures, peripheral airways, alveoli, and collateral channels to achieve lung volume reduction.
The Zephyr EBV System are one way valves inserted into the airways to reduce lung hyperinflation.

Intervention model description
Participants diagnosed as either Collateral Ventilation (CV) Negative or CV Positive. CV Negative participants will only receive the endobronchial valves (EBV). CV Positive participants will receive both the lung sealant and the EBV.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Number of Participants converted from Collateral Ventilation positive (CV+) to Collateral Ventilation negative (CV-) | 4 weeks post lung sealant application | Collateral ventilation status will be functionally assessed and confirmed via CHARTIS® System. Examination of left upper lobe to determine percentage of participants converted from collateral ventilation positive to a collateral ventilation negative state |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Changes Lung volume | 12weeks and 52 weeks post valve implant | Changes in lung volume will be assessed using high resolution computed tomography (HRCT) and target lobe volume reduction (TLVR) |
| Number of participants with improved lung functioning as measured by lung function tests | 12weeks and 52 weeks post valve implant | Lung function will be assessed by spirometry, plethysmography, lung diffusion capacity and capillary blood test |
