BTVA Treatment for Severe Emphysema Study
Part of Lungs & breathing clinical trials.
This study tests a new bronchoscopic treatment called BTVA for people with severe emphysema. It uses heat to shrink damaged parts of the lung to improve breathing.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are at least 18 years old.
- You have severe emphysema, and your doctor has confirmed that one lung has at least two small areas (subsegments) and one larger area (segment) that can be treated.
- You have not smoked for at least 2 months and agree not to smoke during the study.
- Your lung function tests show: FEV1 between 15% and 50% of predicted, total lung capacity ≥100% predicted, and residual volume ≥150% predicted.
- You can walk at least 140 meters (about 1.5 football fields) without stopping, unless you have a leg condition that prevents walking.
- You feel short of breath with everyday activities (mMRC score of 2 or higher).

Other trials that look related to this one.
This trial studies a bronchoscopy procedure that uses heat (thermoablation) to reduce over-inflated lung tissue in people with severe emphysema. If you qualify, it aims to improve breathing and walking ability after trying standard treatments first.
This trial tests a treatment that uses heated water vapor to shrink damaged parts of the lungs in people with severe emphysema. The goal is to improve breathing and quality of life.
This study tests a procedure called bronchial thermoplasty for adults with severe asthma that is not controlled with standard treatments. It aims to see if this can help reduce asthma attacks in people who have already tried or cannot use biologic therapies.
This trial tests a procedure called Endobronchial Thermal Liquid Ablation (ETLA) that uses heated liquid to treat severe emphysema. It is for people with COPD who have very low lung function and shortness of breath, and who have not been able to get relief from other treatments.
This study compares two ways to reduce lung “overinflation” in people with severe emphysema: surgery (LVRS) or a bronchoscopy procedure (BLVR). It aims to see which approach works best and is safest for eligible patients.
This trial tests a cell-based treatment placed into the lung using an airway valve, to help people with severe emphysema breathe easier. You may be eligible if your emphysema is uneven in the lungs and testing suggests your “collateral ventilation” is low, meaning the treatment area may benefit more from blocking airflow.
