{Abstract}: BACKGROUND: Application of vapour ablation as a novel approach to lung volume reduction has positive effects in patients with severe emphysema. The BENTO study is a randomised, controlled, open, multicentre trial, to assess the effects of bronchoscopic thermal vapour ablation (BTVA) in the German healthcare system.
METHODS: Patients with bilateral heterogeneous emphysema of the upper lobes in Global Initiative for Chronic Obstructive Lung Disease (GOLD) stage 3/4 will be enrolled in this trial and will receive either standard medical management alone (according to GOLD guidelines) or BTVA treatment with the InterVapor system together with standard medical management. Patients will be randomised in a 2:1 ratio (treatment group:control group). A total of 224 patients will be enrolled at 15 study sites. The primary endpoint is the change in patient-reported disease-specific quality of life, as measured by the St George's Respiratory Questionnaire for chronic obstructive pulmonary disease patients between randomisation and the 9-month follow-up visit. Secondary endpoints include adverse events, mortality, vital status, changes in lung function parameters, exercise capacity and other efficacy measures at 3, 9 and 12 months.The BENTO trial was commissioned by the German Federal Joint Committee, to demonstrate that this approach is an efficient and safe treatment option in the German healthcare system.
BACKGROUND: The protocol has been approved by the lead ethics committee in Germany (Ethics Committee of the Medical Faculty of Heidelberg) and until present also by the following ethics committees: Ethics Committee of the Medical Faculty of Duisburg-Essen, Ethics Committee of the Medical Faculty of Martin-Luther-University Halle-Wittenberg, Ethics Committee of the State Medical Association of Hessen, Ethics Commission of the State Office for Health and Social Affairs of the State of Berlin, Ethics Committee of the Medical Faculty of Greifswald. The results will be published in a peer-reviewed journal.
