Current Primary Outcome Measures ICMJE |
Change in patient-reported disease-specific quality of life [ Time Frame: 9 months ] Change in patient-reported, disease-specific quality of life based on St. George's Respiratory Questionnaire (SGRQ-C) between randomisation and 9-month visit.
The instrument has 3 domains (activity, symptoms, and impacts) and a total score. A Total and three-component scores are calculated: Symptoms; Activity; Impacts. Each questionnaire response has a unique empirically derived 'weight'. The lowest possible weight is zero and the highest is 100. Each component of the questionnaire is scored separately. Sum of maximum possible weights for each component and Total: Symptoms 566.2, Activity 982.9, Impacts 1652.8. Total (sum of maximum for all three components) 3201.9 Higher weights indicate worse outcomes. The difference in the domain scores and total score at follow-up visits relative to baseline will be calculated and reported.

Official Title ICMJE | Bronchoscopic Lung Volume Reduction in Severe Emphysema Using Thermoablation | ||||||||
Brief Summary | Prospective, 2-arm, randomised (2:1), multicentre, open-label clinical trial in patients with severe emphysema. The intervention arm will be treated with Bronchoscopic lung volume reduction in severe emphysema using thermoablation.The interventional treatment (bronchoscopic lung volume reduction) is compared with the usual conservative standard therapy (GOLD guidelines). | ||||||||
Detailed Description | Currently, there is less data on the use of bronchoscopic thermoablation (BTVA) for the treatment of patients with emphysema. However, the current studies suggest with a high degree of certainty that bronchoscopic lung volume reduction for severe emphysema using thermoablation has the potential to be a necessary treatment alternative. The trial study should therefore contribute to proving the benefit of this procedure as an effective and safe treatment option in order to guarantee emphysema patients sufficient, appropriate and economical care, taking into account evidence-based medical knowledge. | ||||||||

Study Design ICMJE | Allocation: Randomized Intervention Model: Parallel Assignment Masking: None (Open Label) Primary Purpose: Prevention |

Condition ICMJE | Emphysema or Chronic Obstructive Pulmonary Disease | ||||||||
Intervention ICMJE | Device: InterVapor®-System
The InterVapor System uses heated water vapor to ablate the airways and parenchyma within targeted regions of the lung. Lung remodeling occurs after an initial localized inflammatory response and a subsequent healing and repair. The remodeling of the tissue results in reductions in tissue and air volume in the targeted regions of the lung. The remodeled lung tissue does not re-inflate as a result of collateral ventilation. The lung volume reduction of diseased hyper-inflated lung segments after InterVapor treatment is expected to increase elastic recoil by reducing the most compliant segments of the lung, decompressing segments of healthier lung allowing for alveolar recruitment, and improving the mechanical efficiency of the respiratory muscles. These mechanical changes are anticipated to improve pulmonary function, exercise capacity and quality of life. |
