- BACKGROUND: Medical therapeutic options for the treatment of emphysema remain limited. Lung volume reduction surgery is infrequently used because of its high morbi-mortality. Endobronchial lung volume reduction coil (LVRC(®), PneumRx, Mountain View, CA) treatment has been recently developed and has been shown to be feasible and associated with an acceptable safety profile, while resulting in improvements in dyspnea, exercise capacity and lung function. The objective of this study is to analyze the cost effectiveness of LVRC treatment in severe emphysema.
- METHODS:This prospective, multicenter study, randomized with a 1:1 ratio (LVRC vs conventional treatment) will include 100 patients who will be followed up for 1year. The primary outcome measure is the 6-month improvement of the 6-minute walk test: the percentage of patients showing an improvement of at least 54m will be compared between groups. A cost-effectiveness study will estimate the cost of LVRC treatment, the global cost of this therapeutic option and will compare the cost between patients treated by LVRC and by medical treatment alone.
- EXPECTED RESULTS:This study should allow validating the clinical efficacy of LVRC in severe emphysema. The cost-effectiveness study will assess the medical-economic impact of the LVRC therapeutic option.

- 6-month improvement of the 6-minute walk test [ Time Frame: 6 months ]6-month improvement of the 6-minute walk test : the percentage of patients showing an improvement of at least 54m will be compared between groups.
- Cost-effectiveness [ Time Frame: 6 and 12 months ]Cost utility (incremental cost effectiveness ratio) of each therapeutic option according to the EuroQol-5 dimensions (EQ-5D) utility scores.
- Dyspnea [ Time Frame: 6 and 12 months ]Comparison of dyspnea assessed by the mMRC scale, BDI/TDI scale and the Borg scale
- Pulmonary function assessment [ Time Frame: 6 and 12 months ]Pulmonary function tests including FEV1, FVC, RV, TLC, RV/TLC.
- Quality of life [ Time Frame: 6 and 12 months ]Comparison of the St georges questionnaire score and the EuroQoL 5D (European Quality of Life 5 dimensions)
- Morbidity-mortality [ Time Frame: 6 and 12 months ]Comparison of mortality and severe adverse events using a composite score (death, haemoptysis > 150 cc, pneumonia requiring hospitalization, pneumothorax requiring chest tube drainage > 7 days, mechanical ventilation > 24 hours, lung transplantation).
- Exercise testing [ Time Frame: 6 and 12 months months ]Comparison of the 6-min walking test between groups (using the > 25 meters change from baseline as cut-off for clinically significant change).
- Exercise testing [ Time Frame: 12 months ]Comparison of the 6-min walking distance at 12 months using 54 meters as cut-off for clinically significant change.
